THREAD-GUIDE FOR SPINNING-MACHINES.

Specification of Letters Patent.

Patented Apr. 6, MM5,

Application ledr September 9, 1914. Serial No. 860,828.

T0 all whom it may concern Be it knownthat I, JosnrH CoLDwnLL, a citizen of the United States, residing at South Swansea, in the county of Bristoland State of Massachusetts, have invented a Thread-Guide for Spinning Machines, of which the following is a specification.

The primary object of my invention is to provide a peculiar form of thread-guide for use in spinning what is commonly known as novelty yarn, in which one of the threads -in addition to being twisted on the other is wound thereon at predetermined intervals in bunches to form on the yarn what is usually termed seeds. This particular kind of yarn is produced in the conventional type of ring-frame spinning machines by feeding one of the 'threads to the bobbin intermittently andthe other continuously, whereby the continuously-run thread will be wound about the other or ground thread during the time the latter remains stationary, and of course the size of the bunch or seed is determined by the length of time the ground thread remains stationary. In some instances the operation of bunching or forming the seed is produced by passing the ground thread through the ordinary round-wire guide-eye and leading the continuously-run thread on to the same immediately below said eye, but by this arrangement the threads are liable to become tangled, and, furthermore, the winding or bunching is not close or compact.

It is the purpose of my invention, therefore, to provide a thread-guide for machines for spinning novelty yarn in which both threads are guided separately and independently to the point where the continuouslyrun thread is twisted and wound upon the intermittently-run or ground thread to therebyv eliminate all danger of tangling; and a further purpose is to so construct and arrange the guide-eyes, in connection with a guide-member that the filling thread will be wound tightly on the ground thread to produce a compact bunch or seed.

Other objects and advantages of my invention will hereinafter appear, and what I claim as new, and desire to protect by Letters-Patent, is specifically set fort-h in the appended claims.

In the accompanying drawings. which form a part of this specification: Figure 1 is ai view illustrating the application of my invention, only those parts of a spinning machine being shown as required to indicate such application. Fig. 2 is an elevation of my improved thread-guide, and its support, looking at one side of the same. Fig. 3 is a similar view, looking at the other side of the thread-guide. Fig. t is a perspective view in detail.

Like numerals of reference indicate like parts in all the figures of the drawings.

Inasmuch as my invention relating to thread-guides is applicable to the ordinary type of ring-frame spinning-machine employed for spinning novelty yarn, it will be understood by those skilled in the art that the two threads which are twisted together between the guide-eye and the bobbin are fed from between the usual rolls (not shown), arranged in pairs, one for each thread; that pair feeding the ground thread, as 5, being run intermittently to stop or hold the thread at intervals, and the other pair of rolls which feed the other thread, as 6, run continuously; whereby .when the ground thread is running with its companion thread they will be twisted together, as indicated at 7, and when the ground thread is held stationary the other, or continuously-run thread, will wind thereon iinmediately below the eye to form a bunch or seed 8, the twisting and winding being efected by the operation of the revolving bobbin, 9.

In carrying out my invention the threadguide is constructed to form two eyes, 10 and 11, located practically side by side, and through said eyes pass the two threads 5 and 6, respectively, from the guide-bar 16 and feed-rollers, Directly below the eyes, and extending substantially on a vertical line therewith, is an arm or guide-memberl 12, disposed between the threads; that is to say, the thread 5 passes directly from the eye 10 over the front side of said arm and the thread 6 passes from the eye 11 over the rear side thereof, so that the twisting. operation of the threads takes place between this arm or guide-member and the'bobbin, and the winding of the thread 6 upon the thread 5, to form the seed, takes place at the lower edge of the said arm or guide-member'. In the present instance the arm or guide-member 12 is half-round in cross-section, so as to present a tapering lower edge, whereby the winding operation will be effected close up or directly against the edge, insuring a tight bunching or winding and consequently a more compact seed.

In order to guide the thread 5. tothe eye'.

Iy may, and preferably do, provide an y arm 13, disposed above said eye, and" for an attaching shank, as 15, extending one terminal, as 13, from the -eye 11 above the" the filling thread' to the second guide twisted 'liso the purpose of guidingthe thread. 6 to the veye 11 there isa vertical guide-member 14 at one side of said eye abovethe plane of the same an'dterminating at itsk upper endv in a loop 14a., It will be noted that the' guidemember 14, 14a,'is located beyond and slightly to ,the rear of the eye 11, so that the thread 6 will 'be `held a suiiicient distance away from the thread 5, between the guide-y 'bar' 16 and eyestoprevent them from coming together, before passing through thev thread-guides the loop. 14 preventing disengagement of the thread 6 from the vertical portion of the guide-member.

The eyes and guide-members hereinbefore described. 4may be constructed in any suitable ma-nner,but arel cheaply and conveniently 'made of wire, vas herein shown, by bending a single piece of wire upon itself,

then forming-the opposite eyes 10 yand 11..:l

at a suitable distance from the bend toleave eye 10, to form the guide-member f or the thread 5, and extending the other 'terminal from the eye 10 below theheye 11,' to form the arm 12, and on to form the guide-mem-v ber 14 with its loop 14a. Half-round Wire is' used and bent so that theiflat sides will come together in forming. the round shankA 15, and, as will be noted, will present the curved side as the surfaces over which the threads pass through the guide, with respect to the eyes 10, 11, and the guide- members 12, 13, and 14,14, vas well as provide'the desired tapered lower edge for the arm or guide-member 12.

The operation of my improved threadguide will be readily understood from the foregoing description, in connection with the drawings, and it will be apparent .that

in order to provide novelty yarn having seeds o'f different colors two or more ofl thel thread-guides would be employed and' disposed one above another so thatthe intermittently-run groundI thread would pass through the eyesl 10, and the continuouslyrun or filling threads of different colors run through the eyes, 11 separately; the filling thread to the uppermost guide being twisted and/wound upon the ground thread alone,

and wound upon the yarn formed by said first guide, and so on.
