hflACHlNE FOR TURFING FABRlCS.

SPEGIFICTIN forming part of Letters Patent No. 313,710, dated March l0, 1885.

Application filed October 1G, 1884.

To all whom it may concern,.-

Beit known that I, MATTHEW F. CONNETT, Jr., of Springfield, in the county of Sangamon and in the State of Illinois, have invented eertain new and useful Improvements in Machines for Turfing Fabrics; and I do hereby declare that the following isa full, clear, and exact description thereof, reference being had i to the accompanying drawings, in which- Figure l shows a perspective view of my machine as in operation; Fig. 2, a sectional view in side elevation, showing the parts as in position before the needle has been thrust through the fabric; Fig. 3, a view in side elevation of the machine with the parts as in position after the needle has been thrust down through the fabric; Fig. 4, a detail View of the needle bar removed; Fig. 5, a similar View of the needle, and Fig. 6 a similar view of the needle-throw regulating-sleeve.

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 apparatus or 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 fabric to be turfed, which is stretched over a suitable frame, B, in the ordinary and wellfknown way.

C designates a tube, within which slides the tubular needle-bar D. Where the machine is to be operated by hand, this tube forms a handle. Vhere the machine is to be driven by power, this tube is to be attached to a supporting-arm in the same way as the needleguide and presser-foot of-a sewing-machine, and the needle-bar is to be connected in any suitable way with a vibrating needle-arm.

The tube, as shown in the drawings, has a longitudinal slot, E, in its rear side, open at its lower end, and extending well up thetube. The lower end of the tube C is provided at its sides with downwardly-extending ears or lugs F F, which extend parallel with each other, `and are rounded on-their forward and rear ends, so as to permit the free passage of the fabric under them while they rest in contact with it. Upon the tube, just above these ears, is a sleeve, G, capable of being rotated ward, as shown.

(No model about the tube as desired. This sleeve is at one point slotted from end to end, the slot H being of a width corresponding with slot Ein the tube. NVhen, then, the sleeve is rotated so that thetwo slots are in coincidence, there is a clear passage throughout the extent of slot E. The upper end of the sleeve is cnt away to different depths, so to leave portions g g g2, of different heights, forming steps. The sleeve is so formed fora purpose hereinafter to be described. The tubular needle-barD is provided near its lower end with a lug. I, projecting through and moving in the slot E as the bar is reciprocated within tube C. The upper end of this lug is made abrupt, so as to act in connection with the upper end ofthe slot as a stop, to limit the upward movement ofthe bar. The outer force of the lug is, as shown, inclined inward and downward from its upper to its lower end. Just below this lug a portion of the rear side of the tube of the needle-bar is cut away, and a slot, K, is cut in the remaining portion at right angles to the axis of the tube. The needle L istubular, and at its lower end is brought to a pcnctratingpoint by being eut away obliquely or at an angle on its rear side. The upper end ofthe needle is formed with a flange, L', adapted to fit in the slot K in the end ofthe necdlebar. This flange is made of such shape as to just slide and fit within the tube C when the needlebar is drawn upward within such tube. It is also made slightly thinner toward its rear side than at its front, so that the needle, while attached to and carried by the tubular bar, as described above, is capable of being vibrated slightly to carry its point to the rear. For the purpose of giving the needle this motion, so as to form a needle-feed, on the rear side of the needle is the fixed lug or ear M, projecting out through and guided in the slot Ein tube G. The lower end of the lug is on its inner side cut away to leave a downwardly-proj ecting portion, M, having its inner face inclined upward and inbar is thrust downward within its tube, rides up on the sleeve G, so that the needle is swung rearward to make the feed. The main portion of the lug M, coming in cont-act with the upper edge of that portion of the sleeve which is This portion, as the needle- 9 turned across slot E, limits the downward l the same direction with the needle, adapted movement of the needle-bar and needle. By turning the sleeve so that dierent portions of it shall be brought across the slot E the .throw of the needle can obviously be regulated as desired.

Attached .to the rear side of tubular needle L, and extending parallel with it, is the needle'N, whose point stands in rear of and just above the lower end of the needle L.

To swing the needle forward again into position after the inclined projection M on its lug has passed up out of engagement with the sleeve, l provide the spring P, attachedat one end to the lug on the needle, and at the other bearing against the inclined outer face of the stoplug on the needle-bar. The edges of the pobliquely cutaway end or point of the tubular needle are not left sharp, but are rounded, as shown, to prevent cutting the fabric.

If desired, the hollow needle can be provided with a solid point, an opening being made near the point for the passage of the yarn from the inside of the needle.

The operation of my machine is as follows: rlhe fabric to be turfed is stretched on the frame B, and the needle is supplied with yarn or similar material, which is passed down through the needle-'bar and needle and out at the point of the latter. The bar and needle being pulled back, the tube G is held with its bottom ears or lugs against the fabric. rlhe needle-bar is then thrust down, so that the needle carrying the yarn is forced through the fabric until the lug on the needle strikes the sleeve on tube C. Just before this, as the end of the stroke of the needle is neared, the riding of the inclined inner face of the projection on this lug swings the needle to the rear. As the needle is conned in the goods or fabric this movement of it. causes the machine to move forward. The needle being now withdrawn, a loop is formed of the yarn on the opposite side of the goods operated upon.

As the needle is thrust down again through the fabric the sharp supplemental needle impales the yarn in the rear of the needle, and so prevents the loop just made from being pulled out by the movement of main needle As this latter moves downward the yarn is compelled to feed down through the needlebar and tubular needle. The length of stroke ofthe needle, and consequently the size of the loops made, can be regulated, as described, by turning the sleeve on the tube to bring higher or lower portions of it over theslot. rlhe spring P keeps the needle in its normal position, as shown in Figs. l and 2, and returns it to such position after it has been' swung rearward to make the feed by the means already described.

Having thus fully set forth the nature of my invention, what l claim is- 1. In a machine or apparatus for turiing fabrics, in combination with the needle for carrying the yarn down through the fabric, means, substantially as described, moving in 3. In combination with the tubular needle for turting fabrics,having the yarn fed through it, the supplementalneedle carried with the tubular one, and adapted to impale the yarn between the loop last formed and such tubular needle, substantially as and for the purpose described.

4. In a machine or `apparatus. for turting fabrics, a needle for carrying the yarn through the fabric, in combination with the impalingneedle, arranged parallel to the other and traveling in the same direction with it, substantially as shown and described. v

5. In combination with the hollow needlebar adapted to allow of the passage and feed of the yarn or thread down through it, the hollow needle attached to the bar, having its bore connecting with or forming a continuation of the bore of the needle-bar, and at its lower end cut away atan angle to form a penetrating-point, substantially Aas and for the purpose described.

6. rIhe hollow needlebar provided at its lower end with a slot substantially at right angles to its axis, in combination with the hollow needle provided with the flange adapted to tit the slot in the needle-bar, substantially as shown and described.
