APPARATUS FOR CUTTING THE PlLE OF WEFT PILE FABRICS.

SPECIFICATION forming part of Letters Patent No. 597,620, dated. January 18, 1898.

- Application filed July12,1897. Serial No. 644,247. (Nomodeh) To all whom it may concern.-

Be it known that I, GEORGE ROGER, a subject of the Queen of Great Britain, residing at lVarrington, in the county of Lancaster,

England, have invented new and useful Improvements in. Apparatus used in Cutting the Pile of W'eft Pile Fabrics, of which the following is a specification.

The improvements relate to apparatus used in cutting the pile of weft pile fabrics, and have for their object to obtain increased efficiency in such cutting.

' In the cutting of weft pile fabrics, as on the hand or stationary frame, as at present for the most part employed, it is common to stretch upon such frame a length of canvas or other fabric to fol-ma support for the cloth requiring to be cut. This supporting fabric, however, tends in course of time to become depressed and slack of surface at the edges, owing to the frequent necessity the operative is under to bend and reach over the cloth at varying parts along the sides thereof in order to examine the same, in consequence whereof the pile fabric, following the depressions of the supporting material to a considerable extent, presents difiiculties to the operative at'those portions where the line of out has been thrown out of the horizontal and is liable to cause the pile to be cut out of center, or as what is known by the terms toart and frote. To remedy this evil and to carry out my improvements, I provide apparatus which I will describe with reference to the accompanying drawings, in which- Figure 1 is a longitudinal section and Fig.

2 a plan view with portions removed, of a ets 6L2, connecting the side pieces a with the cross-pieces o. of such stretcher, whereby the supporting material I) may be kept tight.

In Fig. 3 the stretcher a. d is shown laterally adjustable at one side only. The ends of this stretcher-frame a a are caused to rest upon suitable supports a of the cuttin -frame 0, while a number of intermediate supports (2 may be provided along the length of the stretcher, as desired, which intermediate supports may be provided or not with vertical adjustment in order to further insure contact of the supporting-cloth with the pile. fabric at any point requisite. One form of vertical adjustment is shown in Figs. 1 and at, wherein the cross-rail d is carried in chairs (1 which may be lifted from the trestle d by the screws d The stretcher or frame a c is shown in the drawings provided with antifriction-rollers e in order that incases where the stretcher is formed of less width than the fabric under operation, as in Fig. 2, where two overlapping fabrics f g are operated upon one cuttingframe, such stretcher maybe the more readily drawn (whether automatically or by hand) to either side of the apparatus; but these antifriction devices may be dispensed with if not required. By means of this stretcher or frame a a, together with the supporting material Z) stretched thereon, the pile fabric lying over the same is supported horizontally and firmly at every part, whereby increased efficiency and uniformity in cutting may be obtained; also, the rigidity of the stretcherframe effectually prevents the bearing down of the sides of the fabric or supporting-cloth by the operative, as before described.

Variations in detail maybe made-such as in the material, design, and construction of the stretcher and the improvements are applicable to cutting either on the long or the short run, whether by hand or mechanical devices, without departing from the peculiar characterof the invention.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim isl. The combination in a machine for cutting the pile of weft pile fabrics, of a frame for stretching the cloth to be operated upon, and an auxiliary frame covered with canvas or like material, supported at its ends upon its ends upon the first-mentioned frame, subthe first-mentioned frame, substantially as stantially as and for the purposes hereinbe- I0 and for the purposes hereinbefore set forth. fore set forth.

2. The combination in a machine for cut- 1 5 ting the pile of Weft pile fabrics, of a frame GEORGE ROGER for stretching the cloth to be operated upon, Witnesses: and an auxiliary frame covered With suitable WILLIAM GADD, material, as canvas, movably supported at GEORGE FREDERICK GADD.
