JOHN F.BLAKE, OF NEV YORK, II. Y.

FABRIC-TURFING IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 342,569, dated May 25, 1886.

Application filed December 10, 1885. Serial No. 185,250. (No model.)

To all whom it may concern:

Beit known that I, JOHN F. BLAKE, aciti- Zen of theUnited States, residing at New York, in the county and State of New York, haveinvented new and useful Improvements in Fabric-Tnrling Implements, of which the following is a specification.

My invention relates to machines for turting fabrics by forming a series of loops alongside of each other on canvas or other material; and it consists in certain novel features of construction, which aie fully pointed out in the following specification and claims, andillustrated in the accompanying drawings, in which- Figure l .is a sectional side View of my machine. Fig. 2 is a similar view of my machine with the parts in a different position. Fig. 3 is a sectional front view. Fig. 4 is an end view.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates the stock, provided with a handle, D. A double crank,having thcwrist-pins a a diametrically opposite to each other, has its bearing in this stock near the handle B, while at some distance from this bearing is the guide-plate O, from which extends a stop, D. The guideplate is provided with an opening, b, Fig. 4t, through which the worsted or other article of which the loops are to be lformed passes, while openings c l in said plate form guides and ful erums for the needle-bar E, which carries the needle F and the loop-holder G. Both the needle-bar and the loop-holder are attached to the donblc-crank-one to each wrist-pin-and, when this crank is rotated by means of the crank-handles c, both the needle and theloopholder have imparted to them fourway77 motions, but always in directions opposite to each other.

The operation of my machine is as follows: The worsted or other tnrng material is passed through the opening b in the guide-plate O, and from there to and through the eye f of the needle F. The parts are then moved to the position shown in Fig. 1, and the needle is thrust through the canvas H until the stop D rests against the same. The crank-handles c are now turned, and as the wrist-pins are earried around by the double-crank the loopholder will slide up close to the needle in such a way as to pass inside of the loop formed by the needle, while the needle will move down until the parts are in the position shown in Figs. 2 and 3. In these figures it will be observed that the loop-holder'has moved up until the bend or shoulder g touched the canvas and could go no farther, While the continued action of the wrist-pin a has caused the whole machine to recede and move the stop D away from the canvas. It must also be observed that the wrist-pin a, as it passed over the center of the double-crank, has caused the loopholder to have a tendency to move toward one side; but as this sidewise tendency does not begin until thepoint ofthe loop-holder has entered the hole made in the canvas by the needle, and is there held fast, the sideward motion is transferred tothe fulcrum of the loop-holder, which is in the guide-plate O, and, as this sideward motion continues, the point of the loop-holder being held fast, the gnide-plate, which is Afast to the stock, and also carries the stop D, is moved sideward, carrying the whole machine to make asideward motion, while it rests on the bend4 orshoulderof theloop-holder, which sideward motion is one halt of the feed-step, and will bring the needle into the position shown in said Fig. 2. As the rotation ofthe double-crank is continued,a similarsideward tendency is imparted to the point of the needle as the same enters the canvas, with a similar result, causing the machine to make the other halfof the feed-step, and again bringing the parts hack to the position shown in Fig. l.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

l. The combination of a stock, A, having at one end a guide-plate, C, provided with the opening b,for the passage of the loopingmaterial, a loop-holder, G, having ala-teral bend or shoulder, g, beyond the guide-plate, a needlebar, E, a needle, F, carried thereby, and a double crank journaled on the stock, and having the wrist-pins arranged diametrically opposite each other and extending from opposite sides of the crank and connected with the loop-holder and needle-bar, said holder and needle-bar passing through and guided by the guide-plate, substantially as described.

2. The combination ot' the stock A, having at one end a plate, O, provided with the projecting stop D, and the opening b,for the passage ol the looping material, aloop-holder, G,
