MACHINE FOR TURFING FABRICS.

SPECIFICATION forming part of Letters Patent No. 332,639, dated December 15, 1885.

Application filed March 11,1885. Serial No. 158,459. (ModeL) To all whom it may concern:

Be it known that I, MATTHEW F. CONNETT, Jr., of Springfield, in the county of Saugamon and in the State of Illinois, haveinvented certain new and useful Improvements in Mation of the outside tube being broken away;

Fig. 2, a similar view of the machine with the needle-bar and needle thrust down; Fig. 3, a longitudinal sectional view of the machine with the needle-bar and needle in a position between that shown in Figs. 1 and 2; Fig. 4, a view in side elevation of the needle-bar and needle; Fig. 5, a detail view of the spring and attached needle-retaining pin removed from the outside tube or sheath; Fig. 6, a detail perspective View of the impaling-foot; Fig. 7, a detail View of the needle; Fig. 8, a similar view showing the parts in position as where the ends of the fork on the needle-bar end engage the arms of the revolving part or carrier of the impaling-foot, and Fig. 9 a detail view of the needle-threading device which I use with my machine.

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 for turfing fabrics; and to this end it consists in the construction, arrangement, and combination of parts, as hereinafter specified.

In the drawings, A designates the sheath or tubular handle of the machine. This sheath is, as shown, provided at its lower end with the parallel lugs or ears B B, which are intended to rest upon the fabric 0 to be turfed,

and are rounded at their ends, so that the fabric can be fed or passed freely under them without catching. The opening between the lower ends of these lugs is, as shown, closed at its rear end by the plate D, forming abrace between the lugs. The rear of the tube above such lugs is provided with a slot or opening, D, and thelugs B B are continued upward alongside such slot or opening. In

the upper portions of the lugs, to the rear of the passage through the tube A,are journaled the pivots e e of the rotary carrier E for the impaling-foot F, to be described more fully hereinafter. The lower end of the tube A, just above the lngs B B, is provided within on its forward side with the shoulder or cam G, whose upper end is beveled or inclined, as shown best in Fig. 3. Fitting and sliding within the sheath or tube A is the tubular needle-bar H, at its upper end provided with a head or handle, H, and near such end having the opening HZthrough which the yarn or other material used is introduced and fed down through the bar. The needle-bar is at its lower-end provided with the longitudinal slot h, extending through it from front to rear, and from its lower end up to a point about midway of its length. The arms h h of the fork, thus formed, are provided with series of corresponding holes, h h, in which can be journaled the opposite ends of the pivot i on the upper end of needle I. This needle, which, as shown, is tubular, is at its lower end cut away at an angle to form a point, the edges thus formed being rounded, so that they will not out the fabric through which the point is thrust. At its upper end the needle has attached to it, and extending down along its front side, the longitudinal rib or lug 1, the lower end of which is beveled or inclined from its outer side inward to the needle. This lug or rib projects above the upper end of the needle, and such projecting portion 'i has its upper end squared or formed with its top at right angles to the needle, as shown best in Fig. 7. 'At the top of the needle, in a line to the front of the needle-bore, are the pivots it, adapted to be journaled in either of the pairs of opposite holes in the fork-arms h h on the needle-bar. About midway between the plane of the lower end of the lug I and the needle-point said needle is notched on its rear side, so as to form the shoulder K at the upper end of the notch. The lower side of said notch is not abrupt, but sloping, as shown in the drawings.

To limit the play of the needlebar and needle within the sheath A a pin, L, is provided, extending across the sheath and through the slot in the needle-bar. The downward throw of the bar will then be limited by the striking of the upper end of the slot against the pin, and the upward throw by the contact of the upper end of the lug I therewith. Obviously, then, by journaling the pivots ofthe needle in higher or lower pairs of the journal-openings h h in the bar the amount of play of the bar and needle can be adjusted. By the same means the extent to which the point of the needle will project beyond the lower end or foot of the sheath-tube when the bar is thrust down can also be regulated or adjusted. Upon the outer side of the tube A, below the pin L, is a fixed collar, M, which, in line with said pin, is notched or cut away at M. Attached tothe end of the pin and adapted to extend down along the tubewhcn the pin is inserted in place is the spring N, which is bent so as to tend to stand outward from the tube, except at its lower end, N, which is bent inward, so as to bear against the outer side of the impaling-foot F at the point at which it is pivoted upon the crossbar E of the rotary carrier E. The spring then tends to keep the cross-bar, and, consequently, the impaling-foot pivoted thereon, pressed inward toward the center of the sheathtube A.

To keep the spring in place with its operative end bearing strongly inward, asleeve, O, is placed on the tube-and adapted to be slid down over the spring and the collar M, so to force and hold the spring downin the notch of the collar. This sleeve is formed within with a flange, 0, cut away at 0' to admit the passage of the spring. This flange comes in contact with the upper edge of the collar M when the sleeve has been slid down in place over such collar.

As shown in Fig. 6, the rotary carrier E is in general form U-shaped, the cross-bar E forming the bottom of the U. The pivots c e extend outward from the arms E E of the carrier on a line near the cross-bar E, and in a plane below that of the cross-bar where the carrier stands with the bar at theinmost point of itstravel.

The impaling-foot proper consists of the bar F,-pivoted upon the cross-bar Eof the carrier, and provided at its lower end'with a series of needle-points, f f f. Its upper end above the pivoted point is on its inner side formed with the shoulder f, adapted to be engaged by the shoulder or abrupt end of the notch on the needle when the latter descends. The action of the spring end when the needle is up keeps the foot normally swung inward and bearing against the needle, so that the shoulder on the foot is in position to besurely engaged by that on the needle as the needle-bar and needle are moved down in the tube A. By the continued downward movement of the needle after the two shoulders are in engagement the foot is carried downward and then outward, revolving the carrier until the cross-bar thereon carrying the foot is nearly in a vertical plane through the pivots of the carrier.

The inout, swinging the cross-bar end of the carrier outward and rearward until the ends of the arms E E of the carrier are swunginward and forward into the track of the lower ends of the fork-arms h h on the needle-bar.

then carries the ends of the arms E E downward and outward until the other end of the carrier, upon which the foot F is carried,- is above the line between the point of pressure of the spring on the foot and the axis of rotation of the carrier. The pressure of therspring will then carry the foot quickly inward, completing the revolution of the carrier and bring ing the foot again against the side of the needle. As the needle now rises and the lug or ribon it passes up off of the shoulder withinthetube A, the action of the spring forcing the foot F forward against the needle causes the latter to swingforward on its pivot into its original position. With this construction, the one spring serves to assist in properly actuating and movingthe carrier and foot, and to keep. the needle normally pressed forward.v

The operation of my turfing-machine is as follows: The yarn or other material to be used is threaded through the needle-bar and needle by the threadingwire R, which at one end is hooked or barbed, as shown in Fig. 9. The end of the wire is passed through the needle and needle'bar and out through theopening in the side of the upper end of the bar. The yarn is then hooked or engaged by the barb, and the wire is then pulled down and out, drawing the yarn with it. is to be turfed is, as usual, to be stretched on a frame. The needle-bar and needlebeing retracted, the sheath-tube A is placed with its lugs B B resting on the fabric. needle-point and the impaling-points on the impaling-foot are now raised above and out of contact with the fabric. The end of the yarn extending beyond the needlep0int rests upon the fabric below the impaling-foot. The needle-bar is now thrust down, piercing the fabric and carrying the yarn down through it. After the needle has descended ashort distance the shoulder on it strikes the shoulder on the impaling-foot, and-thus causes the foot The continued downward motion of the needle-bar" Both the The fabric which IIO to move down until its impalingpointsff impale the yarn end lying on the fabric. This yarn end is thus held from being pulled down through the fabric by the continued downward movementof the needle. Thelug on the needle now comes in contact withthe shoulder within the front of the sheath-tube, and the needle is thus swung back to feed the fabric along for another stroke. As the needle is swung back the impaling-foonas described, moves back with it, thus keeping the 'impaling-points at the'sam'e distance from the needle as at first. By the continued rearward swing of the needle as the latter moves farther downward the impaling-foot is carried backward and outward, and the carrier is rotated until the ends of its arms are swung inward under the desceudingfork-arms h h on the end of the needle-bar. These carrier-arms are then struck and forced downimpaling-points are withdrawn from the yarn on the fabric. carrier rises above the line between the point As soon as the cross-bar on the ofcontact on the spring and the pivotal axis of the carrier, the spring will force the foot and bar inward and upward, causing the carrier to complete its revolution quickly. The needle-bar and needle are then raised, leaving a loop of yarn on the under side of the fabric. As soon as the needle clears the fabric,which,

as described above, has been moved or fed rearward by the swing of the needle,the spring N causes it to swing quickly forward in posit-ion for another stroke to form another loop. As the needle descends each successive time, the impaling-foot impales with its points the yarn between the last loop formed and the needle, so that the passage of the needle downward will not pull out such preceding loop,

'but the yarn will be compelled to feed down through the bar and needle enough for the new loop.

As indicated hereinbefore, the extent to which the needle will project through the fabric can be regulated by journaling the needle-pivots higher or lower in the needlebar fork. The size of the loop can. thus be regulated as desired.

Instead of making the needle-point by cutting away the lower end of the needle at an angle, I contemplate using a hollow needle with solid point, an opening being provided in the side of the needle near its point for the passage of the yarn.

In the drawings the carrier is shown as being formed of a small metal rod or wire having its main portion bent into a U shap e,with the bottom of the U made straight, to form the crossbar pivot for the impaling-foot. The outer ends of the U are bent backward parallel with the arms, and then outward at right angles to form the pivots for the carrier. I- do not limit myself to such construction, as the carrier can obviously be made in other ways, as by bending a bar of metal into U shape and fixing or attaching the pivots to its arms in any desired way. a

The brace D, as the carrier rotates with the impalingfoot, serves the purpose of restraining the outward swing of the lower portion of the foot, so as to keep such portion substantially parallel to the needle. As the foot rises it slides up along the inner side of this brace.

Instead of making both arms of the U shaped rotary carrier long enough to be engaged, as described, by the ends of the fork-arms of the needle-bar, one only of the arms of it can be made long enough to be struck by the bar end.
