THOMAS H. GREENE, OF WOONSOCKET, RHODE ISLAND.

CLOTH -SHEARING MACHINE.

SPECIFICATION forming part of Letters Patent No. 664,040, dated December 18, 1900.

Application filed April 23, 1898.

To all whom it may concern:

Be it known that I, 'IHoMAs H. GREENE, a citizen ofthe United States, residing at Woonsocket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Cloth-Shearing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

The aim or object of the invention is to facilitate the employment of automatic selvageprotector devices or list-savers, as they commonly are termed in the art, in connection with cloth-shearin g machineshaving elastic or yielding cushions applied to the clothbeds or cloth-rests thereof.

The invention consists in a novel and improved combination and arrangement of parts, all as is shown clearly in the accompanying drawings and as first will be described fully with reference to such drawin gs and afterward will be particularly poin ted out and distinctly defined in the claims at the close of this specification. The said drawings illustrate the best form in which I have thus far embodied the invention.

Figure 1 of the drawings shows certain of the parts of a cloth-shearing machine in vertical sect-ion on the dotted line 1 1 of Fig. 2 with my invention applied, the parts being viewed in the direction that is indicated by the arrows at the ends of such line in Fig. 2. Fig. 2is a View in plan of the parts which are represented in section in Fig; 1.

I have shown in the drawings only those portions of a cloth-shearing machine which are most immediately concerned in my inven tion and certain of the parts which are adjacent thereto. v

1 designates the fixed cross bar or support for the cloth-bed or cloth-rest, 2 designates the said cloth-bed or cloth-rest, and 3 designates the elastic or yielding cushion which is applied to the working edge of the said clothbed or cloth-rest. I

4 designates a cover of silesia or other suitable fabric or material which is employed for the purpose of protecting the cushion 3 from wear and injury. The said cushion ordinarily is composed of india-ru bber (caoutchouc) and the cover 4 intervenes between the said cushion and the traveling web of cloth that Serial No. 678,603. (No model.)

is in process of being sheared. In practice the shearing devices (not necessary to be shown) are located in proximity to the clothbed or cloth-rest and operate immediately adjacent thereto at the place where the cloth is upheld by the cushion 3.

5, b, 7, and 8 designate tension and guide rolls over, under, and around which the cloth 9 is led on its way past the shearing devices, the cloth advancing in the direction which is indicated by the arrow in Fig. 1.

1O 10 are the feelers of the selvage-protector devices or list-savers, the said feelers cooperating with the selvage portions of the cloth in customary manner. As usual, these feelers are arranged in pairs at the opposite sides of the machine, each pair cooperating with the detent-disk 11 and the latter in turn engagingin well-known manner with the teeth of the reciprocating rack-bar 12, the said rackbar being in practice actuated by well-known means not necessary to be shown.

13 13 are the respective brackets which serve as supports for the respective pairs of feelers and for the detent-disk which cooperates with the feelers of each pair. 14 14 are the cam-bars on which the said brackets 13 13 are mounted, the said cam-bars engaging and operating in usual manner the vertically-movable teeth or sections 15 15, constituting the end portions of the cloth-bed or cloth-rest 2.

Heretofore it has not been found practicable to employ selvage-protector devices or list-savers in connection with yielding cushions, such as that herein designated 3, applied to the cloth-bed or cloth-rest of a shearing-machine, inasmuch as the cover 4, which it is customary to employin connection with the said cushion, has been so arranged as to interfere with the convenient application of the said selvage-protector devices or listsavers. The cover 4 must be supported and secured in a manner to cause it to be retained in proper position with relation to the cusha support for the said cover 4, which is located entirely above the parts of the selvageprotector devices or listsavers and from which the cover extends across the cushion 3 without any portion of the cover or the said support therefor extending down into theway of the said selvage-protector devices or listsavers. This guards against all interference by the cover with the working of the selvageprotector devices or list-savers and obviates all necessity for modification of the construction of the parts of the latter for the purpose of clearing the said cover. Preferably I extend cover 4, in the manner which is shown most clearlyin Fig. 1 of the drawings,from the deliveryside ofthe cushion,over the said cushion,under and around the roll '7,and back over the cushion, the opposite ends of the cover being wound upon the rolls 15' 15, which are mounted in bearingsin stands 16. By thus returning the cover 4 upon itself two thicknesses of the same overlie the cushion 3 in this preferred embodiment of the invention,although in itself this is not indispensable. As wear takes place of the exposed surface of the cover overlying the cushion 3 the cover may be shifted to bring a fresh place into working position by unwinding the cover from one end of the rolls 15 and winding it onto the other.

I claim as my invention 1. The combination with the cloth-bed or cloth-rest having adjustable end sections and also having selvage-proteetor devices or listsavers combined therewith, substantially as described, of an elastic cushion applied to said cloth-bed or cloth-rest, a cover-support located on the side of the said cushion from which the cloth advances to the latter and a cover extending from the opposite side of the cushion, around said support, and returning upon itself over the cushion.

2. The combination with the cloth-bed or cloth-rest having adjustable end sections and also having selvage-protector devices or listsavers combined therewith, substantially as described, of an elastic cushion applied to the said cloth-bed or cloth-rest, the support 7 at one side of the said cushion, entirely above the said selvageprotector devices or listsavers, and a cover 4 overlying the cushion passing around the said support and returning upon itself over the cushion.

In testimony whereof I afiix my signature in presence of two witnesses.

THOMAS H. GREENE.
