IMPROVEMENT IN MACHINES FR T ISTING AND PLAITING CORUS.

Specification forming part of Letters Patent No. 42,613, dated May 3, 1864.

To all whom it may concern:

Be it known that I, J. T. VILLIAMS, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Machinery for Twisting and .Plaiting Cords; and I do hereby declare that the following is a full, clear, and exact description of the saine, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l represents a planor top view of my invention. Fig. 2 is a longitudinal vertical section of the same.

Similar letters of reference in both views indicate corresponding parts.

In covering or plaiting cords the quality of the work with ordinary machines depends entirely upon the skill of the workman. The cord to be covered is secured to two hooks, and while a quick rotary motion is imparted to the same the plaitin g material is applied by hand. The distribution of the covering or plaiting depends entirely upon the relative speed with which the plaiting-threads, whether in the hands of a workman or attached to machinery, move along. If they move quick the covering becomes thin. 1f they move slow a large quantity of the same accumulates in one spot, and the covering becomes thick. An even distribution of the plaiting-threads therefore can be insured only by insuring a uniform speed as the same are carried along eon the strand or cord to be covered.

To effect this purpose by simple and reliable means is the principal object of this invention, which consists in the employment or use of an endless belt, arranged alongside the twisting-hooks in such a manner that the speed of the plaiting-thread as it moves along .on the strand or cord is regulated by the speed of said belt, which derives its motion from the same shaft which also transmits mo tion to the cord.

This invention also relates to the use of an endless belt for pulling out and laying the required length of strand previous to the twisting operation and to the arrangement of hooks on said belt for the purpose of holding the inished cord while the same is being wound upon the spool.

To enable those skilled in the art to make and use my invention, I will proceed to describe it.

A represents a frame, made of wood or any other suitable material, of vsuliicient strength to form the bearings for the driving shalt B. This shaft bears a large pulley, C, from which a belt extends round a series of pulleys, D, on the inner ends ofthe twisting-hooks E, one only being shown in the drawings. The speed of the twisting-hooks therefore depends directly upon the speed of the driving-shaft. F is a cone-pulley secured to the driving-shaft B, and a belt extending from this cone-pulley over a similar pulley, G, serves to impart motion to a shaft, H, which has its bearings in the upper part of the frame A. The shaft H extends beyond said frame, and mounted on its end is the cone-drum I, from which an endless belt, J, extends over a pulley, 7c, the shaft of which has its bearings in a frame, L, capable of sliding backward and forward in suitable ways in such a manner that the tension of the said endless belt can be regulated at pleasure. The ways L', which form the guides for the frame L, are situated at the opposite end of the room or at such a distance from the frame A as the length of the cords require.

The speed of the endless belt J therefore depends upon the speed of the driving-shaft, and it will increase or decrease in the same ratio as that of the twisting-hooks.

The cord to be plaited is attached to the twisting-hooks in the usual manner, and the plait-ing-threads are applied by hand. In order to insure an even distribution, the little finger of the hand is hooked over the belt, as shown in Fig. 2 of the drawings, and as the hand is thus carried along by the belt with a uniform speed the plaitingthreads are evenly distributed over the surface of the cord. By varying the speed of the endless belt J the quality of the work can be regulated.

The plaiting-threads may, however, be attached to a carrier fastened to the belt J, and the whole work can thus be accomplished automatically.

The main or driving shaft is also connected by a belt or in any other suitable manner with a shaft, M, which has a pulley on it carrying an endless belt, N, on which are one or more frames, O, to which are fastened the ends of the strand-threads. When the strand is drawn out the required length, the threads are detached from the frame 0 by means of a hook, a. The belt N extends over two pulleys, b c, the axles of which have their bearings in a suitable frame, l), at the opposite end of the room or at the required distance from the frame A. In order to facilitate the operation of detaehing the strand-threads from the hook a, said hook is attaehed to a block, d,Whieh is provided with trunnions d', so that it can be turned back.

One or more hooks, e, are fastened to the belt N, and When a iinished cord is removed from the twisting-hooks one end is fastened to the Windingspool and the other to one of the hooks e, which holds it as it is being wound.

The belt N is intended to run alongside the oord to be plaited, and a skillful Workman may gage the speed with which he applies the planting-threads by observing; and following the speed of the belt N.

tion of the Covering or plaiting material.

2. The use of an endless belt, N, with frames 0, or their equivalents, as described, for the vpurpose of pulling out and laying the required length of strand previous to the twisting operation.

3. The application of hooks e, or their equivalents, to the laying-belt N, as and for the purpose set forth.
