VIMPROVEMENT lN MACHINES FOR MANUFACTURING CHENlLLE.

Specification forming part of .Letters Patent No. 37,385, dated January 13, 1863.

To all whom t may concern.-

Be it known that we, GEORGE GoMINGs and LOUIS MENSING, both of No. 50 White street, in the city, county, and State of New York, have invented certain new and useful Improvements in Manufacturing Chenille; and we do hereby declare that the following is a full, clear, and exact description the same, reference being had to the accompanying drawings, forming part of this speciiication.

The ordinaryT process of making chenille is by rst weaving'a web with the warp-threads separated at intervals, next dividing -the said web into strips by cutting the weft-threads in the intervals of the warp, and then twisting the saidstrips. This process is necessarily very slow, owing to the unavoidable slowness of the weavin g. A more recent European -method consists in taking what is called gimp, made by winding round two or more wires,placed side by side, the silk or other fibrous substance which is to form the weft or iilling of the chenille, passing the said gimp between' the threads which are to form the warp or central core of the chenille, cutting the covering of the gimp in such manner as to divide every coil, drawing out the wires of the gimp, and twisting the warp or corethreads together. This method is attended with the serious objection that the chenille thus made is necessarily produced in short pieces or lengths, as the wires must be kept perfectly parallel, which involves the employment of short wires. Long wires cannot be employed owing to the impossibility of bending and coiling them repeatedly upon small rollers, and yet stretching them at the proper moment into a perfectly parallel position.

Unless this parallel position can be perfectly maintained the knife will fail to cut the gimp, and bad work, with waste of material, will ensue. The result is that short wires are always employed, and the chenille produced is consequently made in short pieces about four and a half feet in length.

O'ur improvement consists in certain new and useful devices for manufacturing the article in connection with flexible cords, so that chenille of the best quality unlimited in length may be rapidly and cheaply produced.

Figure l in the accompanying drawings is a vertical section of the machine employed in carrying out our process. Fig. 2 is a plan of the same, partly in'section. Fig. 3 is a perspective view, exhibiting the action of the knife which cuts the weft. Fig. 4 is a central section of the lroll upon which the cutting of the weft is performed.

Similar letters of reference indicate corresponding vparts in the several figures.

A B is the framing of the machine, intended4 when in operation to be suspended round the neck of theoperator and held with the board or end B againstl his breast. 4

AO vis a spool or drum, for carrying the gimp from whose covering of silk or other material the weft or yfillin g of the chenille is to be made, fitted to turn on a fixed spindle, c, n ear the bottom of the frame, under the ycontrol of friction-bands a, applied to its heads.

D .and E are spools, for supplying the two threads of silk or other material which are to compose the warp or central core of the chenille, arranged one at the bottom and the other at the top of the machine, parallel with the spool O, on xed spindles d and e, on which they are fitted to turn under the control of frictionbands d and e. applied to their heads.

f is the gimp, which should preferably be made with two cords arranged side by side parallel or without being twisted together. Gimp with less than two cords cannotbe used.

g is the thread supplied from the spool D, and g* is the thread supplied from the spool E. The gimp is conducted from the spool O over aroll, F, and under a second roll, G, to a larger roll, H, all of which are parallel with the spools O D E, the said rolls either being arranged to turnv on fixed spindles or made with journals to turn in xed bearings in the framing. The rolls F and Ghave square-bottomed grooves for the reception of the gimp, which rests flatwise in or upon the bottoms of the said grooves. The roll H has a fiatbottomed groove, b, in which the gimp lies flatwise, and a second and very narrow groove, i, in the center of the bottom of b for the reception of the warp-thread g, which passes from the spool D through a guide, m, secured to the framing, and enters the said groove i below where the gimp enters the groove b. The gimp and the thread g pass upward over the roller H, and the gimp meets the fixed knife L, which is held in a clamp, M, secured to the framing, and in passing the point of this knife its covering is cut in every coil on the outer side of the gimp, leaving itv intact on the side next the roll and leaving its two internal cords, 5 5, exposed. The thread g* from the spool E is conducted through a guide, j, secured to the framing and round A- into short pieces of a length equal to the cir-" cumference of the gimp, is now seized at the middle of the length of such pieces between-u the two threads g gt, which pass from the roller H, through a guide, l, to a rotating spindle or some other twisting device, while the cords 5 5 pass upward away from the roll H, through grooves in separate rolls J and K, working on spindles secured in the framing.

To produce the above-described operation, the gimpl and the threads g gi* are first conducted round the several rolls and through the guides, as described, and represented in Fig. 1, and the ends of the cords 5 5 of the gimp aremade fast to some fixed point, and the ends of the threads g rf1 fastened to a spindle or other article having a rotary motion, but so arranged as not -to wind the said threads upon it. The operator, who may be a child, then holds the machine with the board or end B of the frame against the front of his body, its weight being supported by a strap passing round the back of the neck, and walks back ward, thereby causing the gimp and threads to be drawn from their respectivev spools. The twist given during this operation to the warpthreads g-g* is merely sufficient to hold the filling or weft, and the chenille is finished by a subsequent twisting operation, which may be performed by the saine means adopted for giving the twist in the old mode of manufacture. In some cases it might be desirable to use more than two warp-threads, and in such case we would use an equal number on each side of the filling.

- We do not claim broadly, the cutting of the covering-threads of gimp and transferring it between threads in order to form chenille 5 but 2. Having the gimp arranged and carried l upon cords f, as herein set forth, so that chenille in pieces of any desirable length may be produced, as set forth.
