IMPROVEMENT IN MACHINES FOR TWISTING, STRETCHING, CLEANING, AND REELING SILK AND OTHER l THREADS.

Specification forming part of Letters Patent No. 58,434, dated October 2, 1866.

To all 'whom t'tmay concern: i

Be it known that I, ToBIAs KUHN, of the city and county of Hartford, and State of Connecticut, have invented certain new and useful Improvements in Machinery for Twisting, Stretching, Cleaning, and Reeling Silk and such like Threads; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a plan, and Fig. 2 a longitudinal vertical section.

The same letters indicate like parts in all the gures.

The object of my said invention is to per form successively and in continuation by machinery the severa-l operations of twistin g, maceratin g, stretching, cleansing, and windin g into skeins silk and other threads that require to be so treated; and instead of placing the spools in the macerating liquid, as heretofore practiced, and which is an objectignable method, by the mode of operation of the machinery as combined and organized by me the threads are twisted directly from the spools and macerated in passing from the mechanism which gives the twist to the mechanism which stretches them, and they are cleaned while under tension and on their way to be reeled into skeins.

In the accompanying drawings, a represents the frame, and b the main shaft, which is to be driven in any appropriate manner.

A drum, c, receiving motion from the main shaft by a band, d, drives a seriesof spindles, e, by bandsf in the usual manner. The spindles e carry the spools g of silk or other fibers, and by friction carry and rotate the fliers h for giving the twist, the silk passing from each spool t'o the outer wing of the flier and thence through a guide on the other wing above the top of the spindle and in line with it. From the fliers the twisted silk passes over a smooth rod, t', made preferably of metal, then down under a like rod, j, in a pan, 7c, containing the usual maeerating liquid and then up over another rod, l. From the'third rod each twisted thread is wrapped around a pin, m, which I prefer to make of metal, and which I denominate the frictionpinsj and the amount of tension required to be given to the threads to stretch them is determined by the number of turns of each thread around its appropriate friction-pin m.

From the pins m the threads are carried around cleaning-rollers n n n, there being one seriesotl three (more or less) such rollers for cach thread. Each thread is passed once or more around the first, the second, and the` third roller of each series. These rollers are made in the form of spools with flanged ends, or, what is equivalent, of smaller diameter in the middle, to prevent the threads from running oif; and the said rollers are mounted so as to turn freely on stud-pins projecting up ward from a frame, o, which is adapted to slide longitudinally in the upper part of the main frame a; and this frame oreceives a reciprocating motion from and toward the friction-pins m from a crank, p, on the main shaft b by a rod, q, connected with a rocking frame, r, which is in turn connected with the sliding frame o by two rods, s s. The required motion may be given by equivalent means. From the cleaning-rollers the threads pass under a guide-roller, t, to a reel, u, on which they are wound into skeins. Thel required slow winding motion is communicated tothe reel from a pulley, fu, on the shaft of the drum c by a band passing around a wheel, w. From a pulley, a', on the hub of the wheel w a band extends to a wheel, y, on the shaft of which there is a pinion, z, which engages a cog-wheel, a on the shaft of the reel. The required motion may be imparted to the reel by other and equivalent means. By the combination above described the threads are twisted, then macerated to be in a suitable condition to be stretched, held back with any desired degree of resistance, depending upon thenumber of times they are wound around the friction-pins, and as they are being reeled up they are held under tension and stretched by the pull of the reel between the reel and the friction-pins, and there rubbed down and cleaned by the back-and-forward motion of the cleaning-rollers; and these series of operations are performed automatically and in succession on the threads instead of being performed separately.

What I claim as my invention, land desire to secure by Letters Patent, is

1. The combination of the mechanism for twisting with the means for stretching and the mechanism Jfor cleaning, substantially as described.

2. The combination of the mechanism for twisting with the means for stretching, the mechanism for cleaning, and the mechanism for reeling, substantially as described.

3. The combination 0f the mechanism for twisting with the apparatus for macerating,

the means for stretching7 the mechanism forv cleaning, and the mechanism for reeling, snbstantially as described.
