32 F.2d 673 | 2d Cir. | 1929
These appeals are from final decrees dismissing bills in equity for infringement of patents No. 1,-507,826 and No. 1,588,354. A separate bill was Bled against each appellee, and separate answers were interposed hy them. Claims 1, 2, 11, 12, 33,14, and 15 are claimed to he infringed by the appellees’ Up-to-Date devices, and claims 2,11, and 12 by the appellees’ so-called German devices of the first patent.
Prior to these suits, in adjusting a previous litigation, the appellees each agreed in writing to admit the validity of the first patent and all the claims thereof, and agreed that they would not infringe the same, nor contest the validity or scope thereof, directly or indirectly. The devices are installed in dolls for simulating the crying sound of a baby — its pronouncing of ma-ma — and comprises a flexible bellows, a short tubular casing in which the bellows is inclosed, and which serves both to operatively support the bellows and prevent foreign matters, such as the stuffing of tho doll, from interfering with the proper function of the bellows. One end of the bellows is anchored, while its other end is free to move, and the anchored end of! the bellows is closed hy an anchoring disc, while the free end is closed by the weighted ■disc. Either disc, weighted or anchored, is provided with an opening, in which is placed a sounding reed. When in an upright position, the weight will act, upon the influence of gravity, to fully expand the bellows, whereby a volume of air will be entrapped, and, when the device is inflated, the weight will collapse the bellows, forcing the entrapped air through the rood, producing the sound.
The prior art reveals the Lloyd patent, No. 1,277,229, which had a cylindrical bellows, necessitating that the bellows be separated from the easing with a wide circular space. Lloyd closed his bellows by oné dise, and then closed the circular space between the bellows and the casing by a separate dise, to prevent foreign matter entering the same and blocking the operation of the bellows. The inventor, in the patent in suit, distinguishes his invention from Lloyd’s by providing a common closure member for the bellows and the casings; that is, the common member closed the easing, so that foreign matter could not enter the chamber, and in this the bellows works, and it also closed the end of the bellows: He used a common closure member, because of his conception of a conical bellows of sufficient diameter at one end to abut the inner surface of the casing.
In claim 14, it is provided that one end edge of the flexible wall is inwardly turned over the margin of the head and secured thereto, and the other end edge of the flexible wall is outwardly turned over an end edge of the easing wall, and means are provided for closing the latter end of the easing and fixing the edge of the bellows wall thereto. In claim 15 frictional, clamping means for effecting -an air-tight seal between the closure member and the flexible body wall of the bellows is provided; also a gravity movable head for the other end of the bellows, and frictional clamping means connecting the latter end of the flexible body wall of the bellows to the head is provided with a sound reed, through which the air is expelled from the bellows in the gravity movement of the head. Thus the inventor advances the idea of the frictional clamping means for effecting an air-tight seal. Other claims, 1,. 2,11,12, and 13, are in substantial accord.
The second patent in suit, No. 1,588,354, is directed to the bellows head or weighted end of the bellows, and provides a frictional clamp holding the movable or the weighted end of the bellows to the weight. Claim 5 calls for a bellows structure which has a tubular flexible wall, a head for one end of the bellows, and a clamping member adapted to engage the bellows wall and frietionally clamp it against the head.
The nearest patent of the prior art was Lloyd’s No. 1,277,229. There the inventor used a tubular easing and a flexible bellows, which was formed of a cylindrical tube of the same diameter throughout. The bellows was closed at one end by a small disc. In applying the closure 'disc, the bellows was first placed in a mandrel, one of the closure discs was there inserted in the end of the bellows, and then the ^protruding edges of the bellows at that end were turned over and folded or pleated against the outer face of the disc and glued together. The mandrel was then withdrawn, and the closure dise was inserted in the opposite end of the bellows, after which the protruding edges of the bellows at that énd were turned over the disc and glued together. The closure dise of the bellows was then glued to a dise of considerably larger diameter, by which the bellows was anchored to the casing; the larger dise was of a size to pass freely into and from the casing, and was attached to the easing solely by means of glue. The larger disc served to close the relatively wide circular gap between the bellows and easing, so that foreign matter, which might interfere with the operation of the bellows, could not enter into the chamber in which the bellows moved.
At that time the only bellows known to the art was formed of a cylindrical tube, and to insure efficient operation it was necessary to provide a casing of considerably larger diameter than the bellows, in order to provide a wide circular clearance between the bellows and the easing, or otherwise the dise at the free or weighted end of the bellows would impinge upon the inner wall of the easing, rendering the bellows inoperative. There were objections to this device. The inventor of the patent in suit conceived that by using a frustro-eonieal bellows, having the end anchored to the casing, of sufficient diameter to abut the inner face of the casing, that end of the bellows could be anchored directly to the end of the casing by a single dise, which additionally served as a common closure member, both for the end of the bellows and the end of the casing, thus dispensing with two discs of different diameters, one to close the bellows and the other to close the casing, and the difficult folding and gluing steps which were required with the use of the cylindrical bellows of the prior art. This was found by the art to effect economy in time, labor, and materials, and provided a more simple, compact, durable, and efficient construction. It was more than an agroupment
The Up-to-Date devices are of two types, one having a easing, a conical bellows having its end edge passing over the end of the casing, and a closure member in the form of a cup pressing the bellows against the casing, and the lip of the cup pressing against an end edge of the easing, and also against the bellows, whereby the conical bellows is held against the easing, and the end of the bellows is closed by the cup, and the eup at the same time closes that end of the casing. ' The other typo is practically the same. The cup in each type closes the other end of the bellows; the open end of the casing presses the bellows against the easing and provides an air-tight seal. The eup is a common closure member.
In the German devices, the juncture of the casing wall, bellows, and closure disc is at an end edge of the easing wall. The bellows is pressed by the disc against the inside of the easing wall, and the disc is to some extent by its own pressure affixed against the inside wall of the casing. The disc is of slightly larger diameter than the inside of the casing bore, and pressure must be applied to force the disc into the easing which holds the bellows tight. The departure thus resulting in the interior wall of a casing forces a new end edge, over which the bellows passes and against which it is pressed by the disc; the disc seating itself upon this newly formed end edge. The shoulder so formed acts to prevent movement of the disc into the easing, and serves to grip the disc to the easing. Glue is used, but this does not avoid infringement. It is largely an additional air-sealing means, to make more perfect that which is carried out by the co-operation of the parts. These devices embody the essential features of the invention of the first patent. The Up-to-Date devices have one edge of the flexible bellows wall turned inwardly over a margin of the bellows head, and clamped thereto by the metal eup, while the other end edge of the flexible bellows wall is turned outwardly around an end edge of the casing wall, and is secured thereto by the eup by frictional pressure, and constitutes a common closure for this end of the easing and bellows chamber. The cup used is the equivalent of the closure plate shown in the patent in suit. This cup embodies the preferred form of the patent, the outwardly flaring lip, which, by reason of its coaetion with an end edge of the easing wall, prevents the possibility of the cup being forced into the casing.
The Up-to-Date devices have the advantage of having the flexible bellows wall turned in reversed direction over the edge,of the air-expelling head and the easing end, respectively, and thereby facilitate the ease and rapid assemblage of parts of the bellows structure in connection with the casing wherein the bellows is housed or inclosed. In the double cylinder form of the Up-to-Date device, the bellows is folded over an end edge and outer side of the smaller or inner easing. In both forms, the disc or eup presses against the inside of the casing. The Up-to-Date device describes the Lloyd way, and follows the patent in suit, in that the junction of bellows walls and easing wall is a.t an end edge of the easing. When the Up-to-Date cup is placed in a position to frietionally press the bellows against the casing wall, the bellows is held in position and the end of the casing is closed for all purposes to provide an operative structure wherein the bellows can expand and contract and thereby creates a sound. This insures the inventive operativeness.
Another cover is provided by the Up-to-Date device, a cap, but this is surplusage from the invention viewpoint. The cup disc closes the bellows and easing. This addition of a part does not avoid infringement. Stafford, Inc., v. Thaddeus Davids Ink Co., 264 F. 111 (2d C. C. A.); Auto Vacuum Freezer Co. v. Sexton Co., 239 F. 898 (2d C. C. A.); Bossert Elec. Const. Co. v. Pratt Chuck Co., 179 F. 385 (2d C. C. A.). In appropriating the common closure member, the German device has taken the substance of the invention, and it is immaterial whether they apply a coating of glue as an additional means of holding the common closure member. The appellee’s devices have all the elements of the claims in suit, and the mere fact of an additional cap does not avoid infringement.
The second patent in suit is also infringed. This patent provides means where
Decrees reversed, with costs.
