MACHINE FOR TURF'ING FABRICS.

SPECIFICATION forming part of Letters Patent No. 337.306, dated March 2, 1886.

Application filed November 5, 1885. Serial No. 181,937. (No model.)

.To all whom it may concern:

Be it known that I, MATTHEW F. CONNETT, Jr., of Springfield, in the county of Sangamon, and in the State of Illinois, have invented certain new and useful Improvements in Machines for Turfing Fabrics; and 1 do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the ac ompanying drawings, in which-- Figure 1 shows a perspective View of my improved turfing-machine with the needle-bar and needle raised; Fig. 2, a similar view of the lower portion of the machine with the needle-bar and needle down; Fig. 3, a side elevation of the machine with portions of the sheath and needle-bar broken away to show the parts more clearly; Fig. 4, adetail perspective view of the needle removed, and Fig. 5 a detail perspective view showing the means for regulat- 2Q ing the upward throw of the needle-bar.

Letters of like name and kind refer to like parts in each of the figures.

The object of my invention is to provide an improved machine or apparatus for turfing 2 5 fabrics,- and to this end my invention consists in the machine and in the parts thereof arranged, constructed, and combined as hereinalter specified. In the drawings, A designates the sheath of 3 the machine, within which fits and reciprooates the needle-bar B.

Both the sheath and the needle-bar, which is hollow, are preferably made, as shown, rectangular or square in cross-section, and are 3 5 open at their rear sides. At the sides of the lower end of the sheath are the parallel feet A A, adapted to rest upon the fabric to be turfed,and to allow said fabric to be fed along rearward past the sheath end as the machine is used, as hereinafter set forth. I prefer to make these feet both of one piece of wire, as shown. To do this one end of the wire at one side is fastened in a socket, a, on the side of the sheath end. The wire is from this socket 5 bent downward, then forward, the substantially horizontal portion thus formed being curved slightly, so as to ride easily over the fabric, then upward, then across through sockets a a, formed on the front side of the sheath,

then downward, then rearward with a slight 5o curve, as on the other side, then upward, and finally forward in the socket a on the sheath side.

The sockets a, a a, and (dare preferably made, as shown in the drawings, of port ons of the material of the sheath bent upward and inward. With this construction the feet can be most cheaply and strongly made and attached to the sheath. Near the lower end of the latter a portion, (5', of one of the sides of the sheath is turned inward to form 9. lug to engage and guide the rear edge 01 the needlebar side. If desired, a similar guidlng lug can be formed on the other side of the sheath. Near its upper end the sheath is provided with 6 notches a* a" in its sides, which receive and hold the sides of plate 0 which spans the open rear side of the sheath, and has attached to it the upper end of the narrow spring D, which extends downward within the sheath to or about to the plane of the lower sides of feet A A. Near its lower end this spring bends slightly toward the rear, and its lower end is formed with the sharp teeth at d. The plate 0 is held firmly down in place by the sleeve E,which fits around, and is capable of being slid along the sheath A. Send plate then, besides supporting sprlng D, acts as a guide for the needle -bar In its movements Within the sheath, engaging the rear edges of 8c the sides of the needle-bar. The upper end of the sleeve E is provided with a lug, E, projecting forward into the needle bar, as shown in the drawings. This lug serves to limit the upward stroke of the needle-bar by 8 5 engaging a stop F, fixed within the bar.

To make the sleeve adj ustable,so that It can be moved and fixed at any desired ad ustment with reference to the sheath, 1 provide the front side of the sheath with a longitudinal series of holes, f f, adapted to be engaged by the end of the spring-catch f. The latter is attached to the sleeve so that its engaging end projects through an opening, f, in the sleeve in position to engage any of the holesff m 5 the sheath. With this construction,upon disengaging the catch or latch f from the sheath the sleeve can be slid-up or down the desired distance,and then locked by letting the catch engage one of the holes ff. This adjustment of the sleeve obviously adjusts the height or position of the lug E with reference to the sheath, and soregulates the possible upward throw of the needle-bar in the latter. The

length of stroke, and so the size of the'loop made, is thus regulated as desired. The handle or head G of the needlebar is preferably attached to the upper end thereof, as shown, by means of a shank or stem, extending down into the upper portion of the bar, and held in place by pins passing through such shank and the sides of the bar. Near the lower end of the needle-bar and within the same is fastened the staple or hasp-shaped piece H, whose cross or transverse portion It extends across the bar beyond the rear side thereof. The needle I is hollow, and preferably made rectangular in cross-section, its lower end being beveled or cut away on its rear side to make a penetrating-point on the front side. On the front side of the needle is a plate, II, which, fitting within the sheath, serves to steady the needle from swinging to one side or the other, and also .as a bearing plate resting against the front side of the sheath as the needle is moved up and down. Attached to the upper portion of the needle, and extending beyond the rear side thereof, are the notched plates L L, provided with notches Z Z, adapted to engage the cross-bar Jr on the needlebar.

To force the upper portion ofthe needle outward, so that when any of the notches are placed in engagement with cross-bar h they will remain so, I provide the leaf-spring M within the needle bar, bearing against the necdle at a point above the level of bar 71. With this construction and arrangement, while the spring acts to force the upper end of the needle rearward to keep the notches and bar h in engagement, it also tends to keep the needle swung on the bar It as a pivot with its lower .end to the front and its shank of course in- .clined in that direction. Automatic feed is thus provided for, as will be hereinafter set forth. \Vhile the plate K and the notched plates L L can be made separate, as desired, and att-ached to the needle, they can of course also be made in one piece therewith to form a complete needle, and I'shall therefore speak of the needle herein as provided or formed with the bearing-plate and with pivotal notches. In its rear side below its pivotal port-ion the needle is provided with an opening, M, connecting with its bore,and with a lip, N, to facilitate the threading of the needle. The rear side of the needle is at its lower end notched or cut V- shaped, so as to prevent the yarn or other material used from slipping as the needle is thrust down through the fabric. If desired, the lower end of this side at the top of the angle upon which the needle-point is cut could be roughened or serrated instead of notched for the same purpose. XVhcn the needle is in place on the bar, the narrow spring D,with' its serrated end, passes down within the needle, as shown in the drawings. The downward stroke of the needle-bar is limited by the lower ends of the bar sides coming in contact with the fabric being turfcd.

Tonllow the needle to be swung by the spring I), as described hereinbefore, so as to stand at quite an angle with reference to the direction of the needle'bar, the lower end of the forward side of the latter is cut away, as shown, so as to leave the lower ends of the bar sides in the form of downwardly-projecting ears, said ears being rounded .at their lower ends.

I do not limit myself to any particular shape or construction of the sheath and needle bar, though I prefer that fully shown and (1e scribed.

The operation of my machine or apparatus is as follows: To thread the needle, the needlebar is first thrust down to its lowest limit, so as to bring the opening M below the toothed end of the spring D within the needle. The end of the yarn or material to be used is then thrust into this opening, and the needle-bar is drawn up. As the needle rises, the teeth on spring D engage the end of the yarn and hold it down, so that when the needle has been raised to its highest point the yarn end will project with the spring end beyond the needle-point. The apparatus is then held perpendicularly over the fabric to be turfed, with the feet A A. on the sheath resting thereon, and the needle-bar is moved downward to thrust the needle through the fabric. As the needle descends, the notch at its lower end engages the yarn and prevents its slipping, so that the proper amount of yarn will be drawn from the supply, and taken down through the fabric by the needle to make the loop. The needlebar is thrust down until the ears formed by the lower ends of its sides strike the fabric. As the needle stands inclined forward with reference to the needle-bar, the fabric will evidently be fed rearward by the needle as it passes down through it. When the needle-bar is raised again, the yarn is held from being drawn upward by the needle by the teeth on the lower end of spring D. As the needle rises, the spring 1) allows it to swing into vertical position as it passes up through the fabric, and, as soon as it clears the latter, swings it forward again, so that its point is in position to pierce the fabric in advance of the former point of penetration. The amount of projection of the needle below the end of the needlebar, and so the distance to which the needle point can pass below the fabric, is easily increased or lessened by causing the pivot-bar h on the needlebar to engage higher or lower notches on the needle.

In order to draw the yarn or other material used closely to the pattern on the reverse side of the fabric, I make the needle pass through the pattern a little farther than it rises above it. As the machine pays out material to form a loop both below and above the pattern, this adjusting 0f the relative amounts of movement of the needle above and below the fabric secures tightness of material on the reverse side of thepattern.

Instead of using a flat leaf-spring serrated at its lower end and projecting down into the needle, as shown and described, I contemplate using, ifdesired, a thin arm or wire roughened or serrated, so as to catch the yarn within the needle in substantially the same way and for the same purpose.

The needle is preferably made square in section, as shown, but can of course be made of any other desired shape.

Having thus described my invention, what I claim is 1. In combination with the sheath and the needle-bar, the stop on the bar,and the sleeve on the sheath provided with a lug to engage the stop on the bar, substantially as and for the purpose shown.

2. In combination with the sheath, the needlebar, the stop on the bar, and the sleeve on the sheath made adjustable along the sheath, and provided with a lug or stop to engage the stop on the needle-bar'and limit the upward movement of the latter, substantially as and for the purpose described.
