This is a suit for damages accrued to plaintiff on account of personal injuries received *150through defendant’s negligence. Plaintiff recovered and defendant prosecutes the appeal.
Defendant owns and conducts a hotel in the city of St. Louis and plaintiff was-dn its employ at the time of his injury as head ash-man and with other duties pertaining to the operation of an elevator. It appears that though plaintiff was originally employed for the purpose of cleaning up and removing ashes from the engine room of the hotel and given the title of head ash-man, he was also directed , by his superior, the engineer, to operate the employees’ passenger elevator in the absence of the regular elevator boy, and to see that such elevator was kept in operation. Plaintiff had been in the employ of defendant seven months at the time of his injury and had recently been charged with the duty of instructing one, Smith, the operator of the elevator referred to, who had been in the service but three days. The testimony for plaintiff tends to prove that as he was passing from the engine room toward the elevator he met Smith, the elevator boy, and Smith said to him, “the elevator is dead,” whereupon plaintiff, together with Smith, went into the elevator and proceeded to operate it, we believe to ascertain the fact with respect to the complaint of Smith, communicated in the word “dead.” By the word “dead,” plaintiff inferred the elevator was motionless because the power was not properly applied through pulling the line as it should be and as Smith had been in the service for only a few days he thought possibly he had pulled upon the line which communicated the power when he should have pulled it down. The elevator is one of those which operates by hydraulic power furnished by means of water pressure in a large cylinder attached. The power is communicated for the purpose of moving the car through pulling a line which passes perpendicularly through same. It is in evidence that, for the purpose of moving the elevator upward, the line is to be pulled down, and for the purpose of moving it downward, the line is to be pulled *151up, and plaintiff thought the car had refused to respond under the hand of Smith because the power was misapplied. Upon entering the car, together with Smith, plaintiff applied the power by properly pulling the line, and it proceeded properly from the basement to the third floor, where a stop was made for one of the chambermaids who came into.the car with a bundle of linen and was conveyed to the ninth floor. After the chambermaid went out, the car proceeded without any trouble to the eleventh, or topmost, floor of the building. Plaintiff then reversed the car by pulling the line upward and it proceeded down as usual to the third floor where a stop was made for an employee en route to the basement for ice. After thus stopping' at the third floor, plaintiff again applied the power and the car proceeded downward a few feet, when his attention was attracted by the rattling of the safety catches beneath, spoken of in the evidence as “dogs.” These safety appliances are affixed beneath the elevator for the purpose of catching and holding it in the event of a fall. Plaintiff was advised that these appliances were slightly out of order and that they sometimes caught in the sides of the ele-' vator shaft when they should not, but it appears no danger inhered in such defect, and he had been advised by the chief engineer how to .dislodge them by the use of a Stilson wrench when such catching occurred. Upon noticing the rattling of the safety catches as though they were scraping on the sides of the elevator shaft, he returned the car a few feet upwards to the third floor for the purpose, we presume, of permitting the safety catches to readjust themselves, as it does not appear he did anything pertaining thereto except to move the car upward a few feet and then start it again on its downward course. It appears plaintiff properly applied the power by pulling the line, to the end of lowering the car to the basement after this stop was made, and when it was a few feet below the third floor, the car suddenly dropped to a point just below the halfway landing be*152tween the first and second floors of the building, at which point it stopped and rebounded with great force. Through the sudden stoppage and rebound of the elevator, plaintiff was thrown from his position at the line upon the floor of the car with one of his feet extended so that it was caught and crushed beneath the doorstep of the elevator and the sill of the halfway landing referred to. There is no suggestion in the case that plaintiff came to his injury primarily through the defective safety catches but on the contrary it appears conclusively the sudden fall and rebound of the car were occasioned by the fact that the cylinder attachment thereto was defective, in that it permitted an intake of air through the valves which occasioned such a disturbance of the automatic arrangement as to precipitate the car forward and cause its rebound, notwithstanding all effort to control it. Such is the negligence relied upon in the petition for a recovery, and it is established by the proof beyond controversy. It appears, too, that defendant had full knowledge for some days of the defective cylinder and valves and that plaintiff was wholly unadvised Avith respect to that particular defect. Indeed, defendant’s negligence in respect to this matter is conceded, and it stands as an uncontroverted fact in the case; but it is said, though defendant was negligent as suggested, such negligence is not available to plaintiff as a cause of action against it, for the reason he was a mere volunteer, in that he was not performing a duty for defendant at the time of his injury within the scope of his employment. There can be no doubt of the general proposition that the master is not liable to respond to his servant for injuries received through his negligence, unless the servant was at the time of injury engaged in the performance of some duty pertaining to the master’s business within the scope of the employment, and of course the principle obtains as well with respect of those engaged in the operation of elevators as in other cases. [Stagg v. Edward Westen Tea, *153etc., Co., 169 Mo. 489, 69 S. W. 391; IV. Thompson’s Com. on Neg., sec. 3907.]
The argument for defendant is that the court should have directed a verdict for it, because as head ash-man and an elevator supply, plaintiff was not required to operate the elevator in the circumstances stated, and stepped aside from the line of his duty to volunteer to do so at the time of his injury. The argument and the principle invoked are put forward in a manner which evinces careful thought and extreme nicety, but it is clearly unsound on the facts of the case. Though it appears plaintiff was employed as head ash-man and for certain general utility purposes, it appears, too, that he was instructed by the engineer, who employed him to run this particular elevator involved at such times as the regular elevator boy had gone to lunch and to see that the elevator was kept in operation. Both plaintiff and defendant’s engineer, who employed him, recited the facts and the duties of his employment to the same effect and furthermore it appears from the testimony of these two witnesses that plaintiff was directed by the engineer to instruct or teach Smith, the new elevator boy, who had been in the service only three days, how to run it. Larkin, the engineer, said when plaintiff Avas not engaged in looking after the two men under him engaged in removing ashes, “It was his duty, by my instruction, to see that those elevators were kept in operation at all times, because we were having considerable trouble to get proficient men in the way of operators.” The same witness said, too, that plaintiff was working over Smith, the elevator boy, because “If Smith should leave the elevator, I would hold Chambee (plaintiff) partially responsible for keeping it in operation.” Indeed, it appears throughout the testimony of plaintiff and his superior, the engineer, that plaintiff was to keep the elevators in operation not only when the elevator boy was out to lunch but at all times, and especially was he charged with the duty of instructing or *154“breaking in” the new boy, Smith, and this of course implied that he should ascertain the difficulty with the elevator or run it for the purpose of demonstration on Smith’s complaint that it was “dead,” unless such word conveyed information or suggested to him that it was out of order and dangerous.' It is entirely clear that the evidence tends to prove plaintiff was acting within the scope of his employment at the time he was injured.
But, it is said, though plaintiff was in the line of his duty, it appears from his own testimony that he knew the elevator was out of order and dangerous, for the reason Smith told him it was “dead” at the time he entered upon its operation. The argument is not that plaintiff’s right of recovery should be denied on the theory of his contributory negligence as a matter of law, for it does not appear that the danger was threatening and obvious and that he acted rashly in encountering it, but the precise argument on this score is, that as plaintiff entered the elevator with the information it was “dead,” he knew it to be out of order and therefore on entering the car with the purpose of investigating the trouble or testing the fact, he assumed the risk of so doing, if the duty to test the elevator was within the scope of his employment. It may be said of this argument, first, that it predicates on a false premise, for though Smith said the elevator was “dead/’ it does not appear plaintiff knew it was out of order. • The matter is to be determined.in the circumstances of the case and in view of the fact that Smith was but a beginner, possessed of limited information' about the operation of the elevator. Plaintiff knew this and it appears, too, that he did not know of the defect which occasioned the car to misbehave and therefore presumed that Smith had made some mistake in pulling the line or attempting to apply the power. Moreover, it is proved in the case that the employees in the engine room and about the elevator understood the word .“dead” to signify, not that it was out of repair, but merely that the power was *155off. Of course, the mere fact that Smith said the elevator was “dead” would indicate no danger to one who understood from that word the power was off, but, on the contrary, it would suggest precisely what plaintiff conceived — that the inexperienced boy had made some mistake in pulling the line by which the power was communicated or discontinued. Of course, dangers that lie in defective machinery affixed for the purpose of furnishing the motive power of an elevator, which defect is discoverable by the exercise of ordinary care on the part of the master and is neither known nor obvious to the servant, is not a risk incident to the employment of one engaged to operate the elevator or instruct others in so doing. It may be that one engaged to ascertain the defect and repair it would take the risk as one incident to such employment in the circumstances of the case presented, if he should be injured while attempting to ascertain the difficulty. But if such be true, it is because of the implied assent to a risk which he must know inhered in the very task he undertook to perform and because of the mode and manner adopted by him in performing it. The principle is without influence on the facts in judgment, however, for the reason plaintiff was not engaged in the precise task suggested; for his duty of keeping the elevator in operation and instructing Smith neither forewarned him of a dangerous defect nor implied that he should make more than a casual examination in the usual way to ascertain why the car was “dead.” In these circumstances, plaintiff’s rights are not to be summarily determined as if he had undertaken by his contract of employment to perform the particular task of ascertaining and repairing the defect, which, of course, implies both knowledge and assent. The defective cylinder and valves, it appears, were well known to defendant and were wholly unknown to plaintiff and nothing in the case suggests that he might have ascertained the fact with respect to them, by a casual inspection, if he were required to make one. *156Plaintiff’s knowledge of the defective safety catches is beside the case entirely, for they in no manner contributed to his injury, and the precise question for decision arises .on the argument that plaintiff assumed the risk of injury from the defective cylinder and valves, of which defect he had no knowledge. We believe in every case the doctrine of assumed risk proceeds on the theory of assent, and of course one may not assent to a risk of which he had no knowledge, unless it be in those cases where the danger is so open and obvious that every ordinarily circumspect person must know it. [Lee v. Railroad, 112 Mo. App. 372, 87 S. W. 12; Garaci v. Hill O’Meara Const. Co., 124 Mo. App. 709, 102 S. W. 594.] But, be this as it may, the rule of decision obtains in this state to the effect that, except in cases where the injury results from the particular mode or manner in which the servant uses the appliance (Harris v. R. Co., 146 Mo. App. 524, 124 S. W. 576), the servant will not be declared to have assumed a risk which arises from the master’s negligence. Under this rule, the servant is said to assume only such risks as are ordinarily incident to the employment, and the matter of his knowledge about abnormal conditions pertaining to the place or appliances is to be determined under the law of contributory negligence by reference to the usual standard of what an ordinarily prudent person might do under like circumstances. [See Wendler v. People’s House Furn. Co., 165 Mo. 527, 65 S. W. 737; Dakan v. Chase, etc., Merc. Co., 197 Mo. 238, 94 S. W. 944; Curtis v. McNair, 173 Mo. 270, 73 S. W. 167; Blundell v. Elevator Mfg. Co., 189 Mo. 552, 88 S. W. 103.] It is obvious plaintiff did not assume the risk.
Another argument advanced is to the effect plaintiff is not entitled to recover on the allegations of his petition for the reason he does not aver therein that it was any part of his duty to perform the service in which he was engaged at the time of his injury. It is true the proof shows the scope of plaintiff’s duties to *157be somewhat broader than the petition avers. It is averred in the petition that plaintiff was employed by defendant as a common laborer for the performance of sundry service, a part of which was the occasional operation of the elevator, and that defendant negligently directed him to use the elevator when it knew of its defective condition. The allegation with respect to what plaintiff was doing at the time he was injured is to the effect that he was engaged in the discharge of the duty of his employment in operating the elevator for the ordinary and usual purpose of carrying employees from one floor of the hotel to another. The argument is, that the petition does not aver plaintiff was engaged in any duty pertaining to the instruction of Smith, the elevator boy, or pertaining to his supervision in endeavoring to ascertain the cause of the elevator being “dead.” In so far as the petition avers plaintiff was engaged in carrying employees from one floor of the hotel to another, the allegation, is proved, for the evidence discloses such to be the fact. So this averment is not unproved. But, true enough, the evidence goes quite beyond it and shows plaintiff was engaged as well in the duty pertaining to his supervision of Smith through demonstrating that the elevator would operate under his management after Smith said it was “dead.” This evidence was received without either objection or exception on the part of defendant. It certainly does not disprove the cause of action relied upon, for the cause of action asserted is plaintiff’s primary right to the exercise of ordinary care on the part of defendant for his safety and defendant’s violation of that right by omitting to perform the obligation which the law laid upon it. [Rice v. C. B. & Q. R. R. Co., 153, Mo. App. 35, 131 S. W. 374; Pomeroy’s Code Remedies (4 Ed.), p. 459, sec. 346, et seq.; Litton v. C. B. & Q. R. Co., 111 Mo. App. 140, 149, 85 S. W. 978.] It is true a party cannot sue on one cause of action and recover on another. [Chitty v. R. Co., 148 Mo. 64, 75, 49 S. W. 868.] And, of course, if a cause of *158action to which the proof is directed is unproved in its entire scope and meaning, the court should direct a ver: diet for defendant but not so, however, when the proof is deficient or does not precisely conform to the. averments in some particular or particulars only. [R. S. 1909, sec. 2021; Litton v. C. B. & Q. R. Co., 111 Mo. App. 140, 85 S. W. 978; Hensler v. Stix, 113 Mo. App. 162, 88 S. W. 108.] Here it appears, instead of there being a failure of proof or the case being one where the facts in evidence disprove the allegation of the petition, all averred were proved and even more. And this, too, without objection or exception on the part of defendant. The evidence tending to show plaintiff went into the elevator at a time when it was in charge of the elevator boy and that in so doing he was within the scope of his duties which pertained to the supervision of Smith, though going somewhat beyond the averment of the petition, pertains to nothing more than a detail relating to his cause of action and at most could present nothing more than a question of variance. The statute commands in respect to variances that—
“No variance between the allegation in the pleading and the proof shall be deemed material, unless it has actually misled the adverse party, to his prejudice, in maintaining his action or defense upon the merits; when it shall be alleged that a party has been so misled, that fact shall be proved to the satisfaction of the court, by affidavit showing in what respect he has been misled, and thereupon the court may order the pleading to be amended upon such terms as shall be just.” (Sec. 1846, E. S. 1909); and further—
“When the variance between the allegation in the pleading and the proof is not material, the court may direct the facts to be found according to the evidence, or may order an immediate amendment without costs.” (Sec. 1847, E. S. 1909.)
Though a slight but unimportant variance appears *159in the proof made from the averment of the petition with respect to the duty plaintiff was performing at the time of his injury, it is obvious defendant was not misled thereby, for it appears he was within the scope of his employment. Even if it were more important, it should be disregarded on appeal, for besides omitting to make the affidavit as required by the statute, defendant omitted to object or except to the testimony when received. By the express statutory provision above quoted, it was the duty of the court to direct the facts to be found in accordance with: the evidence so received, and defendant waived its right to complain on that score through omitting to object or except to such testimony as went beyond the averment. [Hensler v. Stix, 113 Mo. App. 162, 88 S. W. 108; Litton v. C. B. & Q. R. Co., 111 Mo. App. 140, 85 S. W. 978; Mellor v. Mo. Pac. R. Co., 105 Mo. 455, 16 S. W. 849; Chouquette v. So. Elec. R. Co., 152 Mo. 257, 53 S. W. 897.]
Defendant levels an argument against the instructions given by the court at plaintiff’s instance, but it may not be considered, for the reason that though defendant excepted to the giving of these instructions, it does not appear it objected to the action of the court as well in. so doing. The proposition has been recently decided by our Supreme Court in the case of Sheets v. Ins. Co., 226 Mo. 613, 126 S. W. 413, and under the Constitution it is the duty of this court to conform its rulings in all respects on any question of law or equity to the last decision of the Supreme Court on the subject. It is no doubt true that before that decision the profession generally understood an instruction given would be reviewed on appeal if an exception thereto appeared, even though an objection were not otherwise exemplified in the bill of exceptions. Be this as it may, and whatever may be our views on the subject, this -court is without authority to overrule the proposition announced in the authority referred to but on the contrary is in duty *160bound to conform its ruling to the same effect. We have heretofore considered the question and declined to examine the sufficiency of instructions given when no objection thereto appeared in the bill of exceptions though it did appear an exception was saved. These rulings were likewise based on the ruling of the Supreme Court in Sheets v. Ins. Co., supra, see Monroe v. United Rys., etc., 154 Mo. App. 39, 133 S. W. 645; Stevens v. Knights of Modern Maccabees, 153 Mo. App. 96, 132 S. W. 767. When the superior court of the state recedés from the proposition, we will do likewise, but until then the rule is to be enforced.
The court permitted the engineer and others employed about the elevator in the Planter^ Hotel to give testimony as to the meaning of the word “dead,” employed with respect to the elevators there. It is said the word signified the power by which the elevator was operated had been discontinued or detached. It is argued this was error, for the reason that, whatever meaning the word signified when thus employed, dt appeared from plaintiff’s evidence he knew the elevator was out of order at the time he entered the same with Smith. Plaintiff said that when he was informed by Smith the elevator was “dead,” he thought the hand line had been misapplied and went into the elevator to see whether Smith “had worked, the hand line wrong, whether it was dead or not; to see whether it was out of order.” Though plaintiff did say, among other things, that he went upon it to ascertain whether the elevator was “dead” by the misuse of the hand line or if it were out of order, we believe it is obvious that he and all others understood the word “dead” to mean no more than that the power was disconnected and the mere fact he said he intended to see whether it was “dead” in the sense suggested, or out of order, does not show that he understood the elevator was out of order. We see no error in the ruling of the court pertaining to this matter.
*161Plaintiff introduced defendant’s abandoned answer, in which it admitted the elevator was out of repair at the time and that it knew of the fact but pleaded as well that plaintiff had full knowledge to the same effect and was therefore negligent in attempting to operate it in its knoAvn condition. This answer further averred'that plaintiff went into the elevator as a volunteer when it was not part of his duties to do so, etc. On this feature of the case, defendant requested and the court refused, to instruct as follows:
“The court instructs the jury that the abandoned answer of the defendant, which has been introduced in evidence by the plaintiff, must be considered as a whole, and that the admissions which defendant has made in it, if any, are binding on the defendant only as made, and no further. And you are further instructed that such parts in said answer as are- against the plaintiff, if any, are to be considered by the jury equally with such other parts.”
It is argued the court should have given this instruction, for the reason defendant’s abandoned answer, if introduced by plaintiff in evidence, was adopted by him cu-m on ere. There can be no doubt of the general proposition that the answer so introduced in evidence should be considered by the jury as a whole, but nevertheless the court properly refused defendant’s instruction to that effect for the reason it was misleading in that it employed the word “equally” in the concluding line thereof. Furthermore, the instruction, to have been entirely fair, should have told the jury the admissions contained in the ansAver against defendant were presumed to be true. But the real error in the instruction lies in the concluding portion thereof which goes to the effect that such parts of the answer as were against the interests of plaintiff, if any, are to be- considered by the jury equally with those parts which contained - admissions against the interests of defendant. While it was for *162the jury to consider the whole answer and all of its parts, it is not true that the portions thereof which averred plaintiff had full knowledge of the condition of the elevator and that he was a volunteer in the performance of the task at the time of his injury outside of his line of duty were to be considered of equal probative force against plaintiff’s interest as were the admissions therein made by defendant pertaining to the negligence charged. The instruction tended to so direct the jury and was properly refused. [Kersting v. White, 107 Mo. App. 265, 266, 281, 282, 80 S. W. 730.] it would be a harsh rule, indeed, which would operate to bind plaintiff through statements made about his conduct by another equally with admissions made by the same party about his own conduct on any given question.
It appears plaintiff is a young man, bright, active and intelligent, of fair earning capacity and that his injury is not only permanent but severe. He lost the use of his foot through having it crushed by the elevator and was confined to the hospital for many months; suffered great pain of body and distress of mind. His earning capacity is essentially diminished by the permanency of the injury and he is furthermore disfigured and crippled for life. It appears that he will continue to suffer pain, etc. The verdict of $6000, in these circumstances, is not, in our judgment, excessive and it should be approved. .The judgment should be affirmed. It is so ordered.
