The defendant operated in one room in its factory three Fourdrinier machines for drying paper, known as No. 1, No. 2 and No. 3, respectively. Each machine was tended by two workmen, one called a “ machine-tender ” and the other a “ back-tender.” The plaintiff had been in the employ of the defendant as a back-tender on machine No. 3 for about twenty-two months, when, while temporarily tending machine No. 2, his hand was caught in the machinery and injured so that amputation was necessary. The plain tiff brings this action to recover of the defendant damages for his injury ; alleging in the first count that the defendant was negligent in supplying him with machinery for his work which was defective and unsafe; and in the second count that the defendant was negligent in not notifying the plaintiff of a change in the arrangement of the machine by which the danger in using it was greatly increased, and that his injury was caused by said change and failure to notify him thereof.
The facts found by the trial court do not support a judgment on the first count.
The defendant claims that the judgment on the second count is erroneous, because : “ First, the trial court required of the defendant a higher standard of duty in the conduct of its business than the law imposes. Second, the court required of the plaintiff a less degree of care than is required by law.”
As to the second claim: The finding states that the plaintiff had been employed in like capacity on similar machines for *457twenty years, -and was skilled in and thoroughly understood the operation of the same, and that at the time of his injury he exercised due care and skill. The standard of duty applied to the plaintiff by the court was the great skill and high degree of care requisite in operating a machine known to the operator to be a dangerous machine. The degree of care required by law is not greater than this. The real grievance of the defendant is that the court, in applying a correct rule of law, did not find the plaintiff guilty of contributory negligence ; and the claim is urged that negligence on the part of the plaintiff follows as a necessary conclusion from the circumstances detailed in the finding. We cannot say that an application of the rules of law to the detailed circumstances leads necessarily to the conclusion of negligence. We think the question of negligence presented to the court below clearly depends on the conduct of the plaintiff under the special circumstances of the case, involving the exercise of sound discretion in the trier, based upon his experience as to what a reasonable, prudent man would have done under such conditions; and that the “ facts and circumstances are of such a nature that honest, fair-minded, capable men might come to different conclusions.” In such ease the question of negligence is one of fact, and the conclusion of the trier, applying a correct standard of duty, is conclusive. This principle was settled in Harrell v. Waterbury Horse R. Co., 60 Conn. 239, 257, and has been repeatedly affirmed.
The main reliance, however, of the defendant is on its first claim. It appears in the finding that the plaintiff’s employment involved the duty not only of tending machine No. 3, but also, when the back-tender on either of the other machines might be temporarily absent, of supplying his place on that machine, if called upon by its machine-tender ; and that in pursuance of this duty he was working on machine No. 2 when the accident happened. The machines were dangerous to operate, and there was a risk of injury to the skilled workman using due care ; this risk the plaintiff assumed, and his employer was not responsible for an injury resulting from the ordinary operations of the ma*458chine. It is not found that there was any structural defect in the machine that might make the employer responsible. The finding describes machine No. 2 as consisting in part of an open iron frame supporting two rows of steel cjdinders and two series of rolls. Each series of rolls carries an endless band of felt, which guides the wet pulp in its course through the machine in the process of being dried. When the paper becomes broken, as it frequently does, the operator has to seize the end of the paper and place it in proper position between the felt and the cylinders. The main danger to the operator consists in the nearness of the rolls to the rapidly revolving and highly heated cylinders, and the great rapidity with which the pulp or paper passes through the machine. All the rolls are supported on iron stands set in the open iron frame, and are movable; and from time to time some of them are slightly changed in order to tighten or loosen the endless felt. It appears that a week or two before the accident, the defendant changed the position of one of the rolls, by discarding the iron stand on which it was supported in its usual place, and bolting a wooden block to the iron frame for its support in the new position; the roll was thus lowered, and the distance between the face of the roll and of the cylinders on each side of it, reduced one half. This change was not the slight change occasionally made for the purpose of loosening or tightening the felt; it was not made in the ordinary use of the machine for drying paper; it was made in order to run the paper off the machine without running it over the last cylinder of the upper tier, or under the last cylinder of the lower tier, so that these last two cylinders might be employed to dry the felt and not the pulp or paper. And this change, or some other device for drying the felt, was made necessary by the fact that the felt on this machine at the time became too wet for successful operation when the paper was carried through the entire machine. The plaintiff had never known one of the rolls between the cylinders to be thus placed, and they could not be so placed and operated while the last cylinders of the two tiers were used for the purpose of drying paper. No witness was produced on the trial who ever saw a roll so placed be*459fore. The court finds that by reason of this change, “ the space within which the paper must be caught was greatly lessened, liberty of action in the operator obstructed, and the danger and hazard attending the work which the plaintiff was called upon to perform was greatly increased.” Notice of this change was at once given to the back-tender of machine No. 2; but no notice thereof' was given to the plaintiff by the defendant, and he did not” know of the change in the position of the roll when called to work upon the machine at the time of the accident. It was in attempting to seize the paper between the cylinders above this roll that the plaintiff’s hand was caught and injured; and the plaintiff’s injury was proximately caused by the failure of the defendant to notify him of the said change, and the increase in the dangerous character of the machine caused thereby.
The rule of law applicable to these facts is plain. If the change in machine No. 2 was merely an ordinary adaptation of the machine to the purpose for which it was made, which a skilled operator must be presumed to anticipate; such, for instance, as the slight change necessary to keep the felt bands at proper tension, the risk of injury was one assumed by the plaintiff in accepting his employment. On the other hand, if the change was one unknown in the ordinary use of the machine, made to adapt it temporarily to a special and unusual purpose, calling for a difference in operation and greatly increasing the danger, then it was the duty of the defendant to notify the plaintiff before requiring him to operate the machine in its altered condition. O'Keefe v. National Folding Box Paper Co., 66 Conn. 38, 45. It is evident that the court below applied this rule, and so did not require of the defendant a higher standard of duty in the conduct of its business than the law imposes.
But the court did find as a fact that the change made in the machine was of the latter description, and the defendant urges the insufficiency of the evidential facts found, to support the decision of the court upon the real character of the change made. Apparently the evidence on this point was *460not as full as it might have been; but the court had to act on the evidence produced, and we cannot say, on the evidential facts appearing in the finding, that the conclusion reached is logically unsound, even if we could review such a conclusion.
It appears that the change was made by the machine-tender of No. 2, in obedience to the defendant’s direction, and that notice was at once given to the back-tender of that machine, although not to the plaintiff, who was back-tender of No. 3; there possibly may be a question whether the defendant discharged its full duty in notifying those in charge of machine No. 2; so that the real negligence was that of a fellow-servant, the machine-tender of No. 2, in calling the plaintiff to his assistance without advising him of the change. If such question can be considered doubtful, it does not appear that evidence necessary to fully present it was produced on the trial, and no claim of the kind was made in the court below, or in this court.
The other claims assigned in the appeal bearing on the question of contributory negligence, are claims of fact disposed of by the finding. In order to give the defendant every opportunity to urge its claims of law, the judge has detailed the evidential facts quite fully; and one or two especially relating to the plaintiff’s ignorance of the change and his care in operating the machine, are apparently inconsistent with other facts found, and this inconsistency was strongly urged by the defendant in argument. The ultimate conclusion to be drawn from incongruous evidential facts is within the province of the trier, and not reviewable; certainly not, unless the conclusion reached is necessarily inconsistent with clear and settled rules of logic.
There is no error in the judgment of the Superior Court.
In this opinion the other judges concurred.
