Opinion

Shipman, D. J.

These two cases are each founded upon reissued letters patent to George H. Holmes, dated Juno 25, 1878, for an improvement in “take-ups” for looms. The original patent was granted August 10, 1869. The plaintiffs are the owners of the patents. The defences are the invalidity of the reissue, because it contains “new matter” and non-infringement, if the patent is construed by the court to be restricted to the invention as originally claimed. The original patent was for an improved “take-up” in looms for [758]*758weaving cloth. A “take-up” is a device for taking up or rolling the completed fabric upon an intermittingly-moving roller or cloth-beam. The improvement consisted in the arrangement of mechanism for regulating the tension of the cloth. The patented mechanism is described as follows: A ratchet-wheel is so connected with the cloth-beam that a movement of the wheel necessitates a revolution of the beam. This revolution imparts tension to the fabric. Mounted on the axis of this wheel there is an oscillating pawl-carrier, upon which is pivoted a pawl which engages with the teeth of the ratchet-wheel. Motion is imparted to the pawl and its carrier by means of a rod, one end of which is secured to the pawl-carrier. The other end rests loosely in a sliding collar. Motion is imparted to the collar by the crank which turns the “lay,” or “the wooden frame beam which forces up the weft.” The intermediate mechanism between the crank and the collar is the leg of the lay and a pitman.

“ Upon the rod and surrounding it there is a spiral spring, one end of which bears against the reciprocating sliding collar, and the other end of which bears against an-adjustable collar on the rod, which collar is termed a stop-nut in the patent. This collar or stop-nut can be adjusted longitudinally on the rod, so'as to compress the spring more or less, and increase or diminish its tension as may be desired.”

The operation of the mechanism is thus described in the specification of the reissue:

“ It is obvious that when a reciprocating motion is given to the sliding collar, to, the degree of compression of the spring, and the consequent extent of motion of the pawl and the ratchet-wheel, will depend upon the resistance ox-tension of the fabric. Thus, if the cloth is slack, the spring will be but slightly, if at all, affected by the m ovement of the sliding collar, to, the strength of the spring being sufficient to move the pawl, and revolve the ratchet-wheel and take up the fabric, in which case the collar, to, will move with the rod, L, and not slide on it; but when there is sufficient tension on the cloth to overcome the power of the spring, the collar will slide on the rod and expend'its blow or pressure in compressing the sprixxg, and will not throw the pawl or move the ratchet.”'

In the language of the pláintiff’s expert—

“The collar reciprocates positively over a given distance; while the movemexxt of the rod, the pawl-carrier, the ratchet-wheel, and the cloth-beam will vary from time to time, according to the tension of the fabric and the resistance which is offered thereby to the motion of the beam which takes up the fabric.”

The original claim was in these words:

[759]*759"The slotted lever, J, pawl, 7c, ratchet-wheel, I, gear-wheel, G, the rod, L, spring, O, nut, p, and arm, m, the ' lay,’ B, and cloth-beam, F, of the loom, when arranged with reference to each other, substantially as herein shown and described, for the purpose specified.”

On May 16,1876, letters patent were granted to Ira Tompkins and Albert Tompkins for improved take-up rollers for knitting-machines, and thereafter the plaintiffs’ reissue was granted. The reissue was designed to extend the patent to machines for knitting as well as for weaving. The claims are as follows:

“(1) In a take-up device for looms, the combination of the ratchet-wheel,T, through which motion is imparted to the beam which takes up the fabric, the oscillating pawl-carrier, J, provided with pawl, 7c, the rod, L, spring, O, stop-nut, p, and reciprocating sliding collar, m, and operating mechanism, whereby the positive reciprocating motion imparted to the sliding collar is made to turn the ratchet-wheel a greater or less distance, according to the tension of the fabric, substantially as described. (2) In a tako-up device for looms, the combination of the stop-nut, p, the rod, L, spring, O, sliding collar, m, the crank, 31, and suitable intermediate mechanism, substantially as described, whereby the rotary motion of the crank is transferred into the compensatory reciprocating motion of the rod, L, for the purpose set forth.”

A knitting-machine has nothing in common with a loom, for weaving, except that each has a roller upon which the completed fabric is rolled, and a take-up. The office of the take-up, in each machine, is to regulate the tension of the cloth. In a loom, it is necessary that the warp should bo kept taut between the yard-beam and the cloth-beam. A knitting-machine produces a fabric made by a succession of loops, and as the necessities of the manufacture do not require that the yarn or threads should be kept tightly drawn, a smaller expenditure of force is necessary than in a loom take-up. The defendants’ machines are rotary. The take-up rollers, and the frame which holds the take-up, revolve with the machine. Power is communicated to the crank gearing, which actuates the take-up mechanism, by the revolution of the frame upon its spindle. The take-up mechanism proper, of the Holmes and the Tompkins devices, are the same; the differences are in the mechanism by which power is communicated. The crank of the Tompkins device “directly actuates the take-up machinery, instead of actuating the lay of the loom to move the take-up mechanism.”

The plaintiffs’ case is founded upon the position that the Holmes invention was not a take-up for weaving looms only, hut was a take-up device for any looms which require a take-up, and that the orig[760]*760inal patent, by the introduction of the “lay” of a loom as one element of the combination, unduly limited the invention. The plaintiffs a-lsoinsist that while the word “loom,” as defined in the dictionaries, or when used technically, does not include a knitting-machine; yet, as-used in the shops and in the patent-office, it does include such machine ; but that this is immaterial, for whoever uses the loom take-up and employs the same combination in a knitting-machine to take up the fabric is an infringer, and that the crank-rod of the defendant’s device, by which power is communicated to the pawl-lever, is the-obvious mechanical equivalent of the lay and pitman of the Holmes device.
