Opinion

Blodgett, J.

This is a hill to restrain the alleged infringement of patent No. 226,845, issued April 22, 1880, to complainant, for a “machine for enameling or preparing mouldings for gilding,” and for.an accounting. The defenses are:

(1) That defendant does not infringe; (2) that the machine covered b.y complainant’s patent was not the solo invention of complainant, but was the invention of the defendant and complainant acting together; (3) that the machine, or the substantial and operative parts thereof, used by defendant, was invented and put in public use by him more than two years prior to the application Cor a patent by the complainant.

The machine described in the patent is a device for coating mould-ings for picture-frames, looking-glasses, and kindred uses, with an enamel mad.e of whiling- and glue, as a foundation on which to lay the gilding. The process by means of this device consists in running or pushing the moulding to be coated through a box filled with the enameling or coating composition in a plastic condition, whereby a sufficient amount of the composition to form a coat of enamel adheres to the moulding, and the coating thus taken on is smoothed and compacted by steel or iron templets or forms, which fit over the external surface of the mouldings where they leave the box; and in the patented device these templets are placed both at the place of entrance and of exit, and the machine consists of feed-rollers and pressure-rollers, by which the moulding is fed or forced endwise through the enameling box, and held in proper position for that purpose. The patent contains nine claims, all being for a combination of different members of the machine working together to produce the desired result, and the defendant Is charged with the infringement of all [392]*392but the third claim. The proof in the case shows that, as early as 1875, the defendant, Fritts, caused a machine to be made and put in use, a model or illustration of which is in evidence in the case, marked “D. H. Fritts machine;” and there can be no doubt, I think, from the proof, that this machine worked successfully in coating what was known as linings for picture-frames, which is the small or- inner frame lying next to the picture, and usually of a flat or bevel shape. This machine was so organized as to press or crowd the mould-ings endwise through the composition box, and the composition was ■smoothed and compacted upon the surface of the strip so operated upon by means of a templet of the shape of such lining or strip; 'that is, the teinplet was cut so as to fit over the upper cross-section surface of the strip, and in passing through this templet or form the «enamel, which adhered was smoothed, and made compact and firm.

There seems, from the proof, to have been two kinds of machines or devices made by Fritts for this purpose, in one of which the lining <or strip to be operated upon was forced through the composition box by what is called by the witnesses the “chain-feed,” that is, as near as I can understand from the proof, a chain actuated by power was so arranged that by friction contact with the strip it carried or thrust the strip through the composition box. In the other machine, known in the proof as the “D. H. Fritts machine,” the motion was imparted to the strip to be operated upon by friction rollors pressing against the under side of the strips, and the strips were held in place by pressure rollers bearing upon the upper side of the strip so as' to hold the strip in place and carry it steadily into and through the composition box. From a careful comparison of the “D. H. Fritts machine” of 1875, as illustrated in the model and proof, with the mechanism described in the patent, I can see no substantial difference in the mechanical organization or result of the two devices. The Fritts machine of 1875 imparted the necessary motion to carry the moulding into and through the box by friction rollers, operating upon the under side of the machine. The complainant’s machine does the same thing. The Fritts machine of 1875 held the strip to be operated upon with the requisite amount of pressure down upon the friction rollers by pressure rollers, held in place by brackets and adjusted by screws. The complainant’s patent provides for a somewhat different arrangement of the pressure rollers, because the complainant seems, at.least, to assume that, in coating moulding which had an irregular surface, the pressure rollers should bear upon the different parts of those surfaces so as to secure a steady and even motion through the composition box, while the Fritts machine, being intended to operate mainly upon only a strip having a flat or beveled surface, the pressure rollers were arranged so as to give only one bearing.

I cannot see, however, that there is any patentable difference in the two devices. The "patent shows a more complicated machine,. [393]*393and one calculated, at least, theoretically to meet more changes of surface than that specially provided for in the Fritts machine, but still, it seems to me that, when once the idea of carrying a strip, for the purpose of coating it with enamel, through a composition box, by means of friction rollers, and holding it in place by pressure rollers, was shown and illustrated by an operative machine, the number and places for the bearings of the pressure rollers was after that only a matter of mere mechanical adaptation. The moulding or strip to be operated upon forms the bottom of the composition box in both these machines, and hence the sides of the composition box must necessarily be movable to adjust them to the different widths of the strip to be coated or operated upon, and heneo I find that in the original Fritts machino of 1875, and in the complainant’s machine as described in his patent, there is a provision for setting the sides of the composition box farther apart or nearer together, as the necessity may require. Tho plaintiff provides for this necessity by wliat he terms his bracket, IT, leaving the sides of tho box movable so that they may. be held in place by the brackets as they are from time to time adjusted by set screws in a slot upon the frame of the machine; while Fritts, in his original machine, provided a frame which embraced, and, within certain limits, held, the sides of the machine in place, but they were movable in or out to accommodate the width of the strip to bo operated upon by loosening and tightening certain thumb-screws which are shown in the device. The movable sides of the composition box are therefore shown in both machines, although slightly different means are employed for securing the adjustability of the sides, and fastening and holding them in placo. It also sooms to have been found necessary in practico to make the composition box slightly adjustable vertically, so that it may tip to some extent to accommodate itself to the inequalities of the strip of lining or moulding to be operated upon; and the complainant describes in his patent the means by which that element of adjustability is secured by springs and screws. In tho Fritts machine this element of adjustability is obtained by means of certain rubber washers placed upon the bolts which held the composition box to the frame of the machine, whereby a certain amount of yielding or tipping was provided for.

The proof shows that Fritts, after tho construction of his machine in 1875, was not entirely satisfied with its working, and thought it could be improved.
