123 F. 869 | 3rd Cir. | 1903
This is an appeal from a decree entered in the United States Circuit Court for the District of New Jersey against the American Fur Refining Company, appellant, alleging infringement of the eighth claim of patent No. 383,258, granted May 22, 1888, to John W. Sutton, for a machine for plucking furs. The validity of the patent was sustained in Cimiotti Unhairing Company et al. v. Bowsky (C. C.) 95 Fed. 474, a case heard in the Second Circuit, and is not here questioned, the sole issue being alleged infringement. The invention relates to “an improved machine for plucking seal skins and other furs so as to remove the stiff water hairs therefrom without injuring the soft hair or wool of the same.” Scattered among the fur on the pelt of such animals are found stiff, resilient hairs, termed “water hairs,” which it is necessary to pluck or cut off. This, before 1881, was done by hand. Over the index finger, which it will be noted corresponds to the stretcher bar of the latter art, the operator stretched a section of the pelt. By the mouth the fur was then blown down and retained in place by the thumb and finger, a depressing and repressing effect, which corresponds to the separating and holding devices shown later. The toughness and resiliency of the water hairs caused them to stand upright. They were then cut or plucked by shears or tweezers. Hand-plucking was a laborious and expensive process, a girl taking a week to unhair a single seal pelt. The first advance in machine unhairing of such skins was made by Gustav and Ferdinand Cimiotti, who subsequently
“The Invention consists of a machine for plucking seal and other skins, which comprises a fixed stretcher bar, means for stretching and intermittently feeding the skin over the said stretcher bar, a fixed card above the stretcher bar near the edge of the same, a rotary separating brush that Is intermittently moved up- in front of the stretcher bar, a rotary cutting knife and a vertically reciprocating cutting knife working in conjunction with the rotary knife for cutting off the stiff projecting hairs, said rotary cutting knife being provided with a card supported back of the knife; all of which parts are operated from a common driving shaft, so as to produce for each rotation of the same the cutting off or plucking of the hairs projecting from that part of the skin in front of the stretcher bar. * * * The invention consists, further, of the mechanisms by which the motion is imparted from the driving shaft to the different parts comprising the machine, as will appear more fully hereinafter, and finally be pointed out in the claims.”
The eighth claim of the patent, which is here in issue, is as follows:
“The combination of a fixed stretcher bar, means for intermittently feeding the skin over the same, a stationary card above the stretcher bar, a rotary separating brush below the same, and mechanism substantially as described, whereby the rotary brush is moved upward and forward into a position in front of the stretcher bar, substantially as set forth.”
It will be noted that other claims of the patent were for combination or working machine embodying all the effective elements, and that the' eighth claim embodies only certain particular features. Analysis
“On the frame, A, is supported a fixed, transverse stretcher bar, B, which is tapered to a narrow edge, over which the skin to be plucked is stretched. The skin is applied by tapes to the rollers, B', B', which are intermittently actuated by gear wheels operated by a pawl and rachet wheel mechanism from the driving shaft, S, as customary in plucking machines of this class. By the gear wheels and pawl and rachet mechanism the skin is fed intermittently for a small portion of its length over the front edge of the stretcher bar, it being unwound from the upper and wound up on the lower feed roller.”
It thus appears not only that the stretcher bar was fixed, and therefore incapable of effecting the forward movement of the pelt, but that such forward pelt movement was effected direct from the driving shaft by means independent of the stretcher bar.
The next element of the claim is a stationary card above the stretcher bar. The function and use of this stationary card are shown in the specification:
“Immediately above the stretcher bar, B, is arranged a stationary card, E, which is attached to the ends' of the stretcher bar, B, by means of thumb screws. (Not shown in the drawings.) The points of the teeth of the card, E, are close to, but do not touch, the surface of the skin, so that the hair and skin are both straightened as the skin is fed forward. The teeth of the card, E, hold down the fine fur, but permit the stiff hairs to stand up between the teeth, owing to the slow forward movement of the skin, which gives the hairs sufficient time to so adjust themselves.”
Not only is the card’s function thus stated, but to it is attributed, in combination, the effectiveness of the device. Says the patentee:
“The operation of the machine is quick and reliable, the hair being cut off close to the skin, and without injury to the fur, which is held back so as not to be presented to the knives by the action of the stationary card above and the joint action of the separating brush and oscillating guard below the stretcher bar.”
it therefore appears that the teeth of the card effected a preparatory functional operation, and the card’s importance may be estimated by the fact that it is an element in nine of the eleven claims. The other elements of this claim are a rotary separating brush below the stretcher bar (the brush being necessarily movable), and “a mechanism, substantially as described, whereby the brush is moved upward and forward in front of the stretcher bar.”
The proofs show that Sutton’s machine had no effect on the seal unhairing art, and is practically not used therein. An exclusive license thereto was acquired by the Cimiottis, but the machine’s use was confined to some experimental work. It was never used commercially for the unhairing of seals. Gustav Cimiotti testified: “I never unhaired any seal skins commercially on the Sutton machine. Most of the skins that were unhaired on the Sutton machine were done day by day in an experimental way.” Indeed, he goes to the length of saying it was not adapted to unhairing seal skins. His testimony in a former case embodied in this record is explicit: “Q. The
The coney industry has led to the adoption by the defendants of the alleged infringing machine, which, in its movable, oscillating stretcher bar, follows the general line shown in the Lake English patent, which, as we have seen by the statements of complainants’ witness Shaw, was also not accurate or adapted to unhairing seals. Whatever may have been the defects of that machine when applied to the costly experimental work of unhairing seal skins, it is clear to us that its general principles were such that a mechanical adaptation of them so as to successfully deal with the cheap rabbit skins of the coney industry was quite as possible as the adaptation of Sutton’s unused seal unhairing machine to the later industry; and in that adaptation we are clearly of opinion the respondents have not embodied the elements designated in the eighth claim of the Sutton patent. The essential and central feature of respondents’ construction—that around which all its mechanism centers—is its movable stretcher bar. Such a reciprocating stretcher bar, actuated by the same general mechanism, was shown in the Lake patent. This reciprocating movement carried the pelt in the respondents’ machine from the brush to the shears, and it feeds the pelt forward over the stretcher edge as well. Its single reciprocating movement covers approximately a quarter revolution of the power shaft. The three separate mechanisms of Sutton for moving the brush to the stretcher bar, the shears to the same point, and feeding the pelt forward, are, so to speak, unified in the respondents’ single oscillating motion of the stretcher bar, which substantially modifies or effects all three. It is evident that this is not a mere reversal of parts or principles, mere transposition or substitution, but is, in substance, the embodiment of a single threefold effective movement in lieu of the work of three different individual mechanisms. But that is not all. The respondents have found means to unhair pelts by the total omission of the stationary card with its teeth and preparatory work, an essential element of Sutton’s eighth claim. The fur and hair are neither straightened, separated, nor subjected to any such preparatory card work in the respondents’ device. They use a repression bar of the same
We deem it proper to say that the decisions in the Second Circuit involving this patent have been carefully considered. We do not understand that a machine such as is here in question was involved in those cases, or has ever been passed upon. If, however, the construction there given this claim be so broad as to cover the respondents’ device, we cannot, in view of what we have said above, accede to such view.
Finding, as we do, that infringement has not been shown, the decree of the court is reversed, with instructions to dismiss the bill for noninfringement, with costs.
