KNOW ALL MEN BY THESE PRESEIVIS:l

That I, JOSEPH CHASE, of the city and county oi' Worcester, and Commonwealth 'of Massachusetts, have invented certain new and useful Improvements in Machines for Making Clouded Yarn and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure I represents a side view oi my improved machine, and

Figure 2 represents a longitudinal central section.

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

In the drawings, A A represent the main frame of the machine; B the main driving-shaft or cylinder, from which motion is communicated, by means of bands C, to the spindles D, which are arranged in proper bea-'rings at thc front of the frameA Only one spindle, whirl, ring, and traveller are shown in the drawings, as they are sufficient to illustrate my invention, which relates to a diiierent part ofthe machine. In proper bearings upon the top of the machine, and near the front thereof, are arranged the feed-rolls F F', and `just back of them another set of feed-rolls G G. Above thc feed-rolls, and about midway between the two sets of rolls, is arranged the thread-guide II, as indicated in the drawings. I is a spool oi' wool roving or roping, and J a spool of double woollen yarn ready to be twisted. Both ofv these spools turn in proper bearings. The feedrolls F F have a continuous motion imparted to them by means of a belt, K, which runs from a pulley on the end of the cylindersliaft B to the pulley Ii, fast on the bottom roll F, while the feed-rolls G G have an intermittent motion imparted to them by means of the pulley M acting upon the pulley N, fast upon the journal or" the lower feed-roll G. Pulley M has an enlargement, a, on a part of its periphery, which runs in line with the periphery of `pulley N, so that at cach revolution of pulley M the part a will come in contact with the periphery of pulley N, when, as the result of the friction of the two surfaces, motion will be imparted to pulley N, and consequently to the feed-rolls G G, so long,r as the enlarged or projecting part a remains in contact with the periphery of pulley N. In this instance the pulley N is covered with a rubber band, b, and the projecting part a is also rubber, but any other desirable mode of giving an intermittent motion to the feed-rolls G G may be employed.

The operation is as follows: Motion being imparted to the cylinder B in any well-known manner, the feedrolls F F are set in motion, when the thread or threads from the spool J will be drawn through guide H by the feed-rolls F F', and delivered to the windingr and twisting device, which in this instance consists of the spindle D, whirl E, ring c, and the traveller d, which are put in motion by the band G, as before described. The yarn is wound upon the bobbin O as fast as it is delivered by feed-rolls F and F. The ring c is attached to rail I), which is to have a traverse motion imparted to it in the ordinary manner. lhe twisting and winding device, above described, is well known in the art of spinning cotton yarn, as ring spinning, and therefore does not require any further description. While, however, the thread or threads e are passing forward, as above described, from spool and through `eed-rolls F and F', to the bobbin O, the rovingf is fed forwardat regular intervals by the feed-rolls G G, and being on n line with the threads e it passes through feed-rolls F F', and is twisted in with the threads e, giving to the thread, after it has been twisted, thc clouded appearance shown at g g, iig. 2 of the drawings. As soon as the Feed-rolls G G stop the rovingfisdrawn apart between the two sets of feedrolls, and the end ofthe roving remains extended, as represented at it, in close proximity to the threads e and rolls F F, so that it is always sure to enter between the latter, with the former, whenever the feed-rolls G G Feed it forward.` 'l'he roving may bc of any desired color, and two or more different-colored strands of roving may be fed in at the same time to be combined together in the same thread I have shown one mode in which my invention may be carried out, but it is evident that the mechanism cnn be varied in a great many ways. Fluted feed-rolls may be used, and'one or both sets may be driven by gearing, if preferred. 'lhe machine, too, maybe built so as to cloud any desired number of threads at the saine timeA l Having described my improved machine for elondin` yarn', what I claim therein new and oi' my invention, and desire to secure by Letters Patent, is-

1. The combination, in a machine as described, with `the yarn-feed rolls of the roving-feed rolls, or their equivalents, in such manner that while the yarn or main thread is fecl forward, with a continuous motion, the feed of the roving, to the said thread shall be intermittent, as and for the purposes specified.

I 2. .The combination of the yarn-feed rolls with the rolls for producing the intermittent feed of the roving, arranged and mounted in the machine relatively to the said yarn-feed rolls, as and for the purposes herein described. i

3. The combination, with the feed-rolls G G and F F7 of tho yarn-guide H, whereby the.yarn is fed down upon the back of the roll F, while the end of the roving is left in close proximity tothe latter, as shown and described.

4. The combination, with a machine for winding and twisting threads of yarn, of an intermittent roving feeding mechanism for clouding the yarn, substantially as set forth.

JOSEPH CHASE.
