62 F. 389 | 8th Cir. | 1894
This is an appeal from a decree dismissing- a bill brought by the appellant, Matthew Griswold, against the appellees, John B. Ilarker and F. M. Buttan, for infringement of the first two claims of letters patent No. 229,280 to Selden and Griswold, issued June 29, 1880, for improvements in waffle irons. The claims are:
“(1) In a waffle iron, the lunge upon which the pan opens, provided with one of the journals or pivots on which the pan Is rotated. (2) The journals or pivots on which the pan rotates, formed upon or connected, one with the hinge upon which the pan opens, and the other on the handle for rotating and opening said pan.”
In their specifications the patentees say:
“In waffle irons, as ordinarily constructed, the hinge connecting the two parts of the pan has been made separate from the pivot on which the pan rotates, and located on one side of the pan, relatively to- said pivot. Our improvement consists in a novel construction of the hinge connecting- the two parts of the divided pan, whereby one of the pivots or journals on which*390 tlie pan rotates is made to form a part of said hinge, the hinge and pivot being thus brought together, while the opposite pivot or Journal on which the pan rotates is formed on the divided handle, by means of which the pan is rotated, and by means of which, also, either portion of the pan which for the time being is uppermost is lilted for opening the pan. . It further consists in a novel construction and arrangement of the socket in the rim or supporting ring for the reception of the hinge and pivot, whereby the tilting or dumping of the pan is prevented when the cover is raised, and in a novel manner of attaching the wooden handles, as hereinafter described.”
The patentees then minutely describe all the parts of the waffle iron, — the supporting ring upon which the journals rest, and within which the pan rotates; the handle to this ring; the hinge, a part of which forms one journal for the pan; the other journal, which is formed by the divided handle, one-half of which is attached to each half of the pan opposite the journal formed with the hinge; the sockets in which th'e journals rest; the pin which limits the revolving movement of the pan; and the particular method in which they preferred to construct all the parts of the iron. They accomplish their purpose, of bringing the hinge and one of the pivots or journals on which the pan rotates together, by inserting the small end of a wedge-shaped block between the two inner lugs or ears formerly in common use to form the hinge of the pan, and running the pin of the hinge through it. They make this block project beyond the socket provided for it in the supporting ring, and provide it with a head that prevents it from slipping through the socket to the inner side of the ring.
The waffle iron made and sold by the appellees is described in letters patent No. 277,422, May 8, 1S83, to Harker and Williams. It is provided with divided handles which form one of the journals for the rotation of the pan, and the other journal is formed by the hinge which is on the side of the pan opposite the handles. Their pan opens in the same plane with its axis of rotation, and their construction remedies the same defects and accomplishes the same purposes as does the'improved construction described in the patent to Selden and G-riswold. The only variation from the construction of the improvements claimed by Selden and Griswold is that the ap-pellees do not use the block inserted between the double lugs of the hinge and the socket in which it rests to form the hinge journal, but in lieu of this they extend beyond the supporting ring a single, semicylindrical lug from each half of the pan, pin these lugs-together, and thus make the hinge itself the journal.
The court below dismissed the bill on the ground that the claims of the patent to Selden and Griswold must be restricted, in view of the prior state of the art, to the peculiar construction of the hinge t formed with the journal, and the novel construction and arrange-’ ment of the socket described in the patent, and that the appellees did not infringe these claims, when thus construed.
The title of the appellant to this patent, and the utility of the invention it describes, are not contested in this court. A glance at the claims of the patent is sufficient to show that, unless they are restricted by the prior state of the art, the appellees are infringers. It was not the mere form of the hinge described in the patent in
The general rules governing the rights of patentees and inventors are now so well settled that they present hut. little difficulty, but the multiplication of patents to improvements, great and small, upon all classes of machines and implements, constantly presents the difficult question whether or not the claims of the patentees are so much broader than the actual invention they have made that those who are claimed to be infringers are authorized by the prior state of the apt to use the machine or device they present, notwithstanding the patent. This is the question presented in this case. In other words, the question of infringement or noninfringement must be determined by the limitations placed upon this patent by the state of the art when it was issued. McCormick v. Talcott, 20 How. 402, 405.
Turning to the prior state of the art, as it is disclosed by the record before us, we find that prior to the invention of these pat-entees the two halves of the double pan of a waffle iron were hinged together by a, pin passing through two lugs or ears that projected from each half of the pan. Pinches projected from the double pan, —on the sides of it, relatively to the hinge, and at right angles to
But patents No. 24,024, dated May 17, 1859, to J. D. Harrington, for improvements in machines for roasting coffee; No. 27,176, dated February 14, 1860, to E. Webster, for improvements in revolving gridirons; No. 61,478, dated January 22, 1867, to E. J. Smith, for an improved cooking utensil; and No. 96,980, dated November 16, 1869, to Link and Curtiss, for an improvement in steak broilers,— are pressed upon our attention as anticipations of this invention, or restrictions of the scope of this patent. In our opinion they do not have this effect They do not describe waffle irons. They describe cooking utensils consisting of supporting rings and revolving parts composed of divided halves opening in the same planes of the axes of their rotation. Each half is provided with two semicyliu-drical stems on the opposite sides of the revolving parts; and these stems, when the utensils are closed, form the journals on which the revolving parts are supported, and rotated upon the rings or frames. But the sine qua non of a waffle iron is a hinge which will hold the divided halves of the pan continuously together during all the operations of opening, filling, emptying, and closing the pan, so that all these bperations can be conveniently and quickly performed. Such a hinge was a part of every waffle iron referred to in this record. Such a hinge, provided with a journal for the pan to turn upon, was an essential element of the combination claimed by Selden and G-riswold. None of the utensils described in these anticipating patents have such a hinge. Not one of .them is provided with any hinge at all. They are provided with different devices (such as a knob on the end of one of the stems, with a notch in it, into which the corresponding stem may be inserted when the utensil is closed, — patent No. 27,176, supra), by which the divided halves 'of the rotating parts are held together when they are closed; but the moment they are opened these halves become detached, and must again be attached/to each other before they can be turned or operated. A waffle iron constructed on this principle would be useless. From such crude and hingeless utensils as these, or from the old, loosely-swinging waffle iron, without handles, and with its hinge on one side relatively to the pivots on which the pan was journaled, to the hinge provided with one of the journals on which the pan rotates, and the divided handles to the pan forming the other journal, so that the pan would open in the plane of its axis, and could be completely controlled by the handles at all times,
This view is confirmed by the fads that the patent in suit was dated June 29, 1880; that one or both the patentees have ever since been continuously manufacturing and successfully selling the irons constructed under this patent; that one of the appellees was a partner for several years in a firm which purchased these irons of one or both of the patentees; and that we now find him and Ms partner manufacturing- and selling, not the hingeless utensils shown by the patents they plead, nor the old waffle iron, without handles, and with its hinge on one side of the pan relatively to its pivots, but an iron which embodies the very improvements of the patentees, with the exception of the mere colorable evasion of making the hinge itself the journal, in place of inserting the journal in the hinge. Actions often speak louder, and frequently more truthfully, than words. It is not impossible that the reason why the appellees are not using the old devices they plead is that the improvements described in this patent have made them useless and unmerchanta-ble. If this is not so, they can abandon the improvements of Selden and Griswold, and go back to the devices they plead.
In our opinion the first and second claims of the patent in suit are neither anticipated nor restricted by the prior state of the art, nor by the patents pleaded in the answer, and the appellees are infringers of them.
The decree below is reversed, with costs, and the cause remanded, with directions to enter a decree in favor of the appellant for a perpetual injunction, damages, and costs.
