after making the foregoing statement* delivered the opinion of the court.
There being no dispute here about infringement, the sole inquiry is whether the patent is invalid for lack of novelty. The claims, not differing essentially one from the other, are for a combination, but concerning the elements which compose it counsel and the experts seem not to be agreed. According to the testimony of the expert examined in behalf of the complainant the combination “includes an air pump and its hose, and a pneumatic tire and nipple, and mechanism for compressing the hose upon the nipple.” This is manifestly erroneous. Two elements only are designated in the claims, namely* *413ike hose described and the means described for compressing the hose, the several parts of the compressing device being named as elements of the second claim. The hose is called “an air-pump hose,” “wherein a pneumatic tire nipple may be inserted,” but the pump and tire and nipple are not on that account to be read into the claims. This misconception pervades the testimony of the expert for the complainant, and especially bis comparisons of the patent sued on with earlier patents. The hose couplings of the Clark and Thum patents, the lathe dogs of Phillips and of North and Norton, the pipe-vise of Bradshaw, and the snath holders of Clow and Simpson and Harvey, he seemed to think conclusively excluded from consideration, because they did not “show,” “suggest,” “mention, or hint at an air pump, hose, bicycle tire, or nipple.” When asked what novelty there is in the device considered by itself, he answered “the shape of the follower, which enables it to compress the hose upon the nipple,” — a capacity, he added, “which is not found in the British patent or the ‘choker’ model, the nearest approaches to this clamping device.”
When a combination is claimed, there arises an implied concession that the elements are old, and not separately patentable; and in ibis instance' it is evident that the patentee did not understand that the novelty of his combination was to be found in the clamping mechanism, lie asserts no such novelty in the specification, but, distinctly to the contrary, says: “The compressing device may be of various constructions, but that which I prefer, as least costly and most convenient, is shown to consist in an elongated loop,” etc. Indeed, it is too plain to admit of discussion that the device shown, composed of a loop, a follower, or gib, and means, such as a thumb screw, for moving the follower, considered by itself, in the light of Hie prior art, contains no novelty even of form. In its physical parts, their order of arrangement and law of operation, it is completely anticipated by the various and familiar devices already mentioned. It is objected to the Clark hose clamp that it is heavy and unwieldy, but it is not invention to convert such a device into “a light, quick-acting, easily applied temporary fastening,” capable of “being used in the confined space among the spokes of a bicycle wheel,” without the aid of “wrench or screw-driver.” The criticisms of the witness upon the hose clamp of the Thum patent are of the same character, and fail to touch the question of the mechanical identify of one device with the other. Of the lathe dogs or lathe-work holders of Phillips and of North and Norton it is said that they are intended to bite on opposite sides of the article to be held ¡.herein, and that, if used to compress a hose on a nipple, the joint between the opposite points of compression would leak; but, again, it obviously involves no invention to employ in such a device concave jaws, capable of compressing the hose equally at all points around the nipple, like the concave jaws of monkey wrenches which are used to grip and hold or turn the metallic pipes in common use as conduits of gas or water.
But still more striking and complete, even in appearance and in details of construction, is the anticipation found in the device shown *414in the British patent of Hillman. It consists of a loop, a D-shaped 'follower fitted to the loop on the inside, and a thumb screw, by the turn of which the follower is moved one way or the other; and, like the device in question, it is used for the purpose of compressing a hose inserted within the loop. The sole difference is that the side of the follower next to the hose is convex, instead of concave, the design being to so compress the tube by turning the screw as to prevent any escape of the air or gas. The essential nature of this contrivance — its mechanical identity with thé device of the patent — is not affected by the suggestion that it takes the place and performs the office of a valve. It is not a valve, and does not operate like one. It is a screw clamp, designed to compress a rubber tube, not about a nipple or inner tube, it is true, but so as to close the passage; and in ,the mode of adjustment, construction, and operation of its parts, except that the convex side of the follower impinges on the tube, it is identical with the device under consideration. It is a choker, and, as the opinion below states, “the choker devices are constructed and intended for use with the nipples of bicycle tires, and are used for the purpose of choking the nipple after- the tire has been inflated, and thus preventing the escape of gas”; but while the opinion concedes the manifest truth, that, by changing the form of the follower, this device could be used in the combination of the patent in suit, it is added as a matter to be borne in mind “that the complainant is not claiming the clamping device alone, but is claiming it in connection with other elements, the entire combination producing a single unitary result, namely, the inflation of any bicycle tire.” 67 Fed. 246, 250. If this proposition were conceded, the result accomplished, it is to be observed, was not new. The successful inflation of any and all bicycle tires had already been accomplished, and the means employed had been the same and in the same combination, excepting solely the difference between the earlier couplings and this clamping device. The passage quoted and other expressions in the opinion show that, in the judgment of the court, the combination of the claims included, besides the clamp and hose, the air pump, and perhaps the tire and nipple, as asserted by the expert and by counsel.. If that were so, the unitary result of inflating any bicycle tire might be said to have been made possible; but actual inflation, it is evident, could only be produced in single successive instances, and in each instance the particular tire operated upon would constitute, for the time being, an essential part of the combination. In other words, the invention consists of a combination of elements or parts, say five, four of which were contrived and are employed to produce a stated effect upon the fifth, which plays no part in the operation except passively to receive the effect. The pump, hose, clamp, and nipple are employed to inflate the tire, which upon completion of the operation is detached, and the combination thereby dissolved, to be reconstructed only by the incorporation of another tire or a reincorporation of the one detached. Only when in use can the combination be complete, and every use involves a reconstruction and dissolution of the combination. If there has ever been granted a. patent for such a combination of mechanical elements, designed to expend their force *415among themsel ves, and to effect or affect nothing hevond, it has not come to our knowledge; hut whether, if granted, it could be upheld, need not now he considered.
These claims, as we have seen, are for a combination of two elements, the clamp and the hose described. Whether, in a true and proper sense, there is a combination, we do not stop to consider. The result which the patentee sought to accomplish was to dispense with the metallic couplings theretofore used, and provide means of fastening (lie open end of the hose of an air pump directly upon nipples of various sizes. “It is my object,” says the specification, “to provide a universal air-pump hose and couplings, which may be employed for inhaling the tires of any machine.” But, as touching the question of patentability, it is no more to he said of this mode of coupling that it was designed for, results in, or produces the ultimate inflation of any or all tires, than it would he to say of a coupling for fire hose that it was designed for and resulted in the throwing of water or the extinguishment of tires. It is the immediate mechanical result of the device or combination which is pertinent. That result here is the making of a direct air-tight connection between the hose of an air pump and the nipples of pneumatic tires, and the question is whether there is patentable novelty in the means devised for accomplishing that result. The result itself is not novel. The clamp, considered alone, contains nothing essentially new in construction, operation, or result; and it hardly need be said that the hose is not new, though it is affirmed in the brief for the appellee that it was “absolutely new with Johnson to provide an air pump with a hose having an open end into which the nipple of a pneumatic tire may be inserted.” Besides the repetition of the assumption that the pmnp is included in ' the claims, this statement is at fault. Before the date of this patent metallic couplings, inserted in the ends of hose, and so constructed as to he screwed upon or into the nipple of the tire to be inflated, were doubtless in common use, hut open-ended hose could not have been unknown. From necessity, in the course of the manufacture or preparation of hose for any use, their ends were open before couplings could be inserted, and often afterwards, when, by accident or design, the couplings had been removed. There could be, therefore, no novelty in a hose with open end, whether connected at the oilier end with a pump or not. Even if in some way air-pump hose had alwajs come into existence attached to air pumps at one end, and supplied at the other with metallic fastenings, and never before had been seen with open ends, it could hardly he thought to require more than mechanical skill to remove a misfit: coupling, and insert the nipple directly in the hose; and, that done, it would need only the grasp of the operator’s hand, or the application of some familiar form of clasp, to make the union air-tight. Indeed, the manufacture or production of hose with metallic fastenings necessarily involved the idea and presence of hose with open or free ends into which nipples of different sizes could be inserted; so that even without proof or suggestion that such hose had been used, either with or without other clamp than the hand of the operator, it would be impossible to concede that this patentee was the first “to provide *416an air pump with a hose having an open end.” The simple truth is that metallic couplings were not adjustable, and, in order to use a single pump and hose upon a variety of nipples, Johnson rejected the metallic coupling, and, in order to compress the end of the hose about the inserted nipple, brought into use, as the preferred means of accomplishing the result, the clamp described in his patent; and, if thereby he made an invention, he was entitled to claim broadly “the combination of a piece of open ended hose with the clamp described.” The hose being described in the claims as an air-pump hose, whatever the effect upon the scope of the patent, cannot disguise or change the essential character of the combination, which is the same whether the hose is attached to or is to be used in connection with an air pump, water pump, siphon, or any other conceivable mechanism.
But, whether deemed to be broad or narrow, the combination is without patentable novelty. Like combinations, for the same or like uses, are common, and have been long practiced in the use of hose ¡for conveying water, gas, and air. For a conclusive example we need only recur to the British patent of Hillman. That device, it is conceded, was used in connection with the nipples of bicycle tires, its position in use being between the metallic part of che nipple and
the tire. The annexed illustration corresponds to figure 4 of the patent. With that device present in position on the nipple, the end of the nipple in the hose, and the necessity for tightening the joint developed, he would be a poor mechanic, indeed, who could fail to perceive that, by substituting a concave for the convex follower, he might convert the choker into the necessary clamp. It is evident that the clamp, without changing the form of the follower, could be used in lieu of the choker, and, if
so used within British territory, would be an infringement of Hill-man’s patent. Necessarily it is anticipated by what it infringes.
The decree of the circuit court should be reversed, and the bill dismissed for want of equity; and it is so ordered.
