Letters Patent No..7'3,9.30, dated January 28,' 1868.

IMPROVEMENT IN BRAID-llIAlKINGk MAGEINE.

TO ALL WHOM IT MAY CONCERN:

Be it known that. I, GEORGE REHFUSS, of lihiladelphia, Pennsylvania, have invented a Braid-Making Machine; and I do hereby declare the following to be afull, clear, and exact description of the same.

My invention consists of a self-acting or latch-needle, operating in combination with a plate and a lever, as fully described hereafter, so as to produce a braid from a thread carried bythe lever. 4

In order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation, reference being had to the accompanying drawing, which forms a part of this specication, and in which-` Figure 1 is aside view of my improved braid-making machine.

Figure 2, a sectional elevation and Figures 3 to 6, inclusive, views illustrating the operation of the machine.

A is the base-plate of the machine, to the .top of which are secured standards a a, and to the upper ends of the latter is fastened a circular work-plate, B. At the under side of the work-plate are two projections, 6 in which turns a shat't, O, and in the work-plate, and in a lug, c, on the projection 6, slides a vertical rod, D, to the upper end ci' which is secured. an ordinary self-acting or latchneedle, d, there'- being an opening, cc, in the work-plate, through which the needle passes. To a pin, e, at the outer. side of the plateb, is hung a lever, E, into a slot, at one end ofjvlrich projects a pin on a disk, F, secured to the shaft C, and through aslot in the inner end of the lever E, and into the rod D passes a pin or screw, m. To a' pin at the inner side 'of the projection 6 is hung a bent lever, G, which passes through slots in the plates A and B, and in the upper end of this lever, which is curved towards the needle d, is an eye, y. On the shaft C is a grooved pulley, H, at one side oi' which is a cam, 7i, and against the lutter bears the lower end of the lever G, which is maintained in contact with the cam by a spring, n. A curved spring-plate, o, is secured to one end of the upperside ofthe plate B, the opposite end ct the spring-plate bearing on the plate B', between the edge of the 'same and theislot ag, and from the top of the-plate B projects an a1m,p,in which are openings'ss. A thread, t, from an adjacent bobbin, is passed through theopenings in the arni p', through the eye y, in the lever G, i-n the form of a loop, round the shank of the needle o?, below the latch ot' the same, and beneath the spring-plates. i

The parts of the machine arenow brought to the position shown in tig. l, a rotary motion in the direction of its arrow i's imparted to its shaft C, when-the operation of the machine will be as follows: The lever G will drst move to the position shown in iig. 4, and will carry the thread t across the needle, above the latch of the same.v The needle willlthendescend, its hook seizing the thread. Asthe needle passes downward through the loop on the shank, the latter will elosc the latch, and, as the needle descends belowthe worin-plate, the loop will slip off the upper end, and on to the new loop, which is held by the hook of the needle. The lever G will now. move to its ti'rst position, and the` needle will rise to the position'shown in iig. 4, the new loop, as the needle rises through the same, opening the latch.

As the above-described operations are repeated, a succession of loops are made on and drawn from the needle, a 'braid being thus formed, which `is attened by the pressure of the spring-plate o, between which and the work-plate it passes as it is withdrawn from the machine.

The above-described apparatus is very compact, and especiallyadapted for use in connection with ordinary v .sewing-machines, to the stand :v of any of which it may be attached, as shown in tige. 1 and 2, a band passing from' the pulley Il to a similar pulleyon the driving-shaft turning inthe stand of the machine.

I claim as my invention, and desire -to secure by Letters Patent- 1. The combination ofthe plate B, lever G, rod D, and its needle d, the wholebeing constructed, arranged, and operated substantially as'and for `the purpose described.V l

2. The combination of the above and the spring-plate o, for the purpose set forth.

In testimony whereof, I have signed my name to this specification in thepreseuce of two subscribing witnesses.

GEO. REHFUSS.
