LACOMBE, Circuit Judge
(after stating the facts as above).
[1] A patentee obtains a monopoly only of what he discloses and claims.

Reference to prior art is useful to clear up obscurities, but it is in the specification (with such light as the drawings ma!y throw upon it)’that we are to find what the alleged invention is. When its language is plain and positive, its disclosure specifically set forth in unmistakeable terms, it is not to be modified by later theories of experts so as to enlarge the claims beyond their legitimate scope. Especially true is this when the art is a crowded one, and certainly this art was crowded when the patentee filed his application.
[2] .Turning now to the specifications: It is indicated that dress forms had already been made in sections, adjustably secured to each other so as to increase or decrease the size of the whole form or parts thereof. The patentee states that his objects are to provide novel and simple methods of adjusting portio'ns of the form without changing or adjusting other portions. The present controversy is concerned with the adjustment of neck and shoulder pieces. That part of his device is very clearly described in the paragraph quoted below which read in connection with Fig. 2 of the drawings, indicates precisely what his construction is and how it operates. In the drawing 5 is the neck section, 3 and I¡. are the shoulder sections. Figure 2 shows the inside of the back, half of the form. The inside of the front half of the form, with similar adjustable connections between the sections is shown in Figure 1 which need not be reproduced.
The specifications state:
“For adjustably connecting the shoulder sections to the neck section I have provided a construction which not only holds the shoulder sections properly spaced'from the neck sections, but also, serves to guide said shoulder sections as they are adjusted toward and from the neck neck sections. The device herein shown for accomplishing this comprises a slotted member 10 secured to the shoulder section and overlying a second slotted member 11 secured to the neck section. These slotted members are clamped together by means of clamping holts 90, and the slotted members .10 have studs 91 rigid therewith which play in the slots of the member 11. By this construction, the shoulder section is always maintained in its proper position relative to the neck section and may also be clamped to hold it properly spaced from the neck section. 92 are other slotted members which are secured to the neck sections both froht and rear at the lower, edge thereof, and which are adjust-ably secured to the lower corners of the shoulder sections by clamping bolts 93."
Except in abnormal cases the line of the human figure, especially the female figure, from the base of the neck to the tip of the shoulder (the so-called shoulder line) makes an angle more or less wide with the horizontal. It is apparent that if á shoulder section were moved away from the neck section horizontally the shoulder line would be
Page 343
distorted, there would be a step up between the outer tip of the neck section and the inner tip of the shoulder section, which would be most undesirable. The patentee’s device avoids this—as he says, “the shoulder section is always maintained in its proper position to the neck section.” His adjustable connection is not horizontal, but parallel to the drawing. He does not state that it is thus parallel, but it would not operate as his device does operate unless it were thus parallel, and the drawing shows it parallel. This device comprises: First, a slotted member
11 secured to the neck section by a fastening
11a. Second, a similar slotted member
10 secured to the shoulder section by a fastening
10a. The slots overlie each other; through them there passes a clamping bolt
90 (the clamp is not shown in the drawing): as the shoulder piece moves in or out the bolt plays forward or back through the slots. The slotted member
10 has a stud integral therewith which plays in the slot of member
11. It is manifest that with this means of adjustment the movement in and out of the shoulder section cannot be horizontal but must be on the line of the shoulder. However far off the shoulder section is moved, its shoulder line prolonged would exactly meet the shoulder line on the neck piece, and vice versa. In the device there are four points always in the same straight line and from that line it is impossible for the slots to depart without distortion or breaking of the device. Two of these points are the fastenings
10(i, 11a; they are permanently fixed. Whether they are clamped so tight that the parts
10 and
11 cannot move radially, or whether they are so loosely clamped that these parts could move on them as axes is immaterial. If they were loosely clamped there might be such radial play of the slotted members—provided either the clamping bolt
90 or the stud
91 were removed. But the patentee includes them both as .elements of his combination, and when both are in the slots radial play of the slotted members is impossible. The patentee very aptly expresses this in claim 4, which states that the means connecting the upper portion of each shoulder section to the neck section permits “said portion of the shoulder section to move in and out only.” With this means of connection there can be no tilting of the shoulder. up or down; to the line of the shoulder as designed by the maker of the form it must always conform. If the form is to be used for making a waist for a woman whose shoulder line is less sloping, or more sloping, it would seem that this device would not permit an adjustment to conform thereto: it could provide for broader or narrower shoulders but not for a markedly different shoulder line.
Turning again to the drawing, we see that the connection between the lower part of the shoulder section and the neck section is not parallel to the shoulder line, but horizontal. If its adjusting devices were arranged in the same way as in the upper connection the top part of the shoulder section would be moving out on one right line and the bottom part on a different fight line. Therefore the lower connection is arranged with a single slotted member 9%, and with the clamping bolt 93 only, the stud being dispensed with; thus securing a pivotal connection.
There is much testimony as to the great commercial success of the “later Ufford dress form.” If, however, the form which has thus
Page 344
commended itself is the one of which samples were submitted on the argument as complainant’s commercial dress form, increase of sales seems of little importance, because its upper connections between shoulder and neck pieces have been so modified as to admit of the very tilting of the shoulder which the device of the patent would effectually prevent. The shoulder piece has a greater range of movement than “in and out only.” Complainant’s expert admits that in these commercial forms there is, for upper connection, one slotted member instead of two so that pivotting is permitted at the top' of the shoulder section instead of the device preventing it; he also admitted that in the complainant’s forms which he had seen the shoulders could be raised slightly. How much this enlarged range of adjustment over that which the patent called for contributed to commercial success we do not know and the record does not disclose. Presumably the greater the adjustability of' a dress form, the more acceptable it would be to the user.
However it is not necessary now to pass upon the question of the validity of the patent. Defendant’s connecting device (a toggle joint both above and below) most certainly is not such an one as will restrict the movement of the shoulder section so as to permit its upper portion “to move in and out only.” On the contrary, it can be also moved horizontally and up or down, as the user may wish. Ufiord’s patent covered a connection in which the shoulder line of the original form must always be maintained; no carelessness of adjustment could disturb it. In defendant’s form whether it be maintained or not depends on the will of the user, who can not only broaden the shoulders on the given line but can also tilt them so as to secure a different line. About this there can be no dispute, complainant’s expert admits it and examination of Exhibit A Defendant’s Form demonstrates it. If the connections which complainant uses in its commercial forms were patented, Exhibit A might infringe them, but we cannot see how it infringes a patent the very object and purpose of which is absolutely to insure movement in one direction only.
The decree is reversed, with costs.
