248 F. 693 | 7th Cir. | 1918
(after stating the facts as above).
United States patent to Way, No. 858,931, July, 1907, shows a coin-operated device where the towels hang suspended by rings or eyelets in the towel on a horizontal rod near the top of a box. On depositing the coin the nearest towel so suspended is moved slightly forward on the rod and slides down and downwardly and forwardly inclined continuation of the rod, falling on the bottom of the box. The user .reaches into an opening in front of the box, grasps the towel, brings it out, and having used drops it, and it continues its course down the rod and rearwardly into a receptacle into which the rod guides it.
Rousso in his specification points out that his device may also be coin-operated, though he does not specify the mechanism whereby this may be done. Rousso differs from these others in that his towel-retaining member — -the rod — rises from the shelf on which the towels rest, passes through the grommets in the forward part of the towels as they lie on the shelf, and above the stack of towels, and then forward and downward below the shelf as described, so that the user grasps and raises up the upper towel, brings it forward, and then downward.
It is insisted that one Straub conceived a towel rack which shows features of Rousso, and for which United States patent No. 1,038,984, was granted him September 17, 1912. This device shows, secured to a wall of the room a pair of brackets oh which is' fastened a plate or board a convenient distance from the wall, and on each end of the plate within the inside line of the brackets there is a bail which when locked in position is of inverted U-shape. The bails may be opened and closed very much as they are in letter or bill files in common use. The towels are strung onto these bails hanging over the plate between it and the wall, and the user may take a towel thus suspended, raise it and make use of it, and then drop it down on the front side of t;he bail where it hangs suspended over the forward edge of the plate, and there remains until removed, unless indeed a user takes one of the soiled forward hanging towels and makes use of it, returning it either to the front, or swinging it over the bails to the rear; the towels after their use begins hanging on both sides of the plate, and the forward towel being in truth the more convenient for the user to grasp. But assuming that the user of the Straub device takes the towel from the rear side, -he lifts it upward and forward and drops it down; but he leaves it suspended over the forward edge of the same plate in precisely the same manner as are the towels on the other side. There is in fact no shelf in Straub’s in the sense that there is a shelf in Rousso’s device, for it is only the edge of his towel which rests on the plate; the toweis themselves hanging down both before and after their use. These differences are substantial and eliminate Straub’s structure from the prior art. The District Court rightly held the claims valid.
There is evidently advantage and utility in such a chain system, but it may not with impunity be incorporated in a device which infringes the patent of another. While Rousso’s patent contemplates a rod as the towel-retaining member, it is apparent that a rope or chain or the like may be so disposed as to be the «mechanical equivalent of the rod. 'Where, as here, the chain is positively held so that it comes up from the level of the shelf through the towels, and is by means of the door held higher than the towels and by means of the rod carried forward, we find that the chain has been so employed as to be the equivalent of the upward, forward and downward bend of Rousso’s gooseneck rod, and performs its identical function in substantially the same manner.
But it is claimed that one Fetherolf, prior to Rousso’s invention date, designed and used a device showing this chain method for securing and serving individual towels, and that, if appellant’s device infringes Rousso; Rousso’s patent is in turn thus anticipated in this prior use. Without undertaking to review the evidence on this subject, we are satisfied that the District Court which heard the witnesses properly concluded that the Fetherolf prior use was not sufficiently shown to overcome the validity of Rousso’s patent.
We are not required to determine, and we do not decide, that the •employment of a chain or similar device for stringing and locking the towels necessarily infringes on Rousso’s gooseneck-rod combination; but we do find that, employed as it is in the particular device of appellant, held while in use upward and forward, it is the equivalent of Rousso’s gooseneck rod, and presents in appellant’s device the full combination of certain of Rousso’s claims, thereby infringing.
We find that the infringement is predicable on claims 1, 2, 3, and 5, but not on claims 4 and 6. These last include the element of an extension rearward of the guiding rod, after passing below the level of the shelf. We find nothing in appellant’s chain as if hangs over the rod and into the chute, which is the equivalent of the rearward
The decree will be modified in accordance with the views here expressed, and as so modified affirmed, with costs.
