SPECIFICATION forming part ef Lettere Patent No. 791,615, dated June 6, 1905.

Application filed February 27 To @ZZ whom t may concern:

Be it known that I, Tnnononn PnnNTIou FARMER, a citizen of the United States, residing at Southwest Harbor, in the town of Tremont, county of Hancock, State of Maine, have invented an Improvement in Rings for Spinning and Twisting, of whiohthe following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production ofa novel ring for spinning or twisting yarn.

My novel ring presents an annular groove open at its inner side for the reception of a thread-receiver or traveler, the raceway being maintained in operative position with relation to a spinning-rail or other thing for carrying the same by a suitable inclosing case, (herein represented as composed of multiparts and separable.) In practice for the best results the raceway will be composed of a nonmetallic substantially frictionless material, so that as the thread-receiver is made to travel rapidly in the raceway-groove the raceway will not become unduly heated or wear the thread-receiver, it being essential, it will bel understood, to avoid undue friction between therapidly-moving thread-receiver and the raceway, especially when, as hereincontemplated, the thread-receiver is to be revolved by the yarn at an 'excessivelyrapid rate of speed. One of the best frictionless materialsl known to me at the present time is wood prepared to resist friction. The thread-receiver or traveler, as it might be called, comprises a body that enters the groove of the raceway, the body having an arm that is extended from the raceway at its inner side, said arm being bent to enable the thread to be engaged therewith, so that the thread in the rotation of the spindle may drag the thread-receiver in a cir- `cular path in the raceway. The outer extremity of the arm referred to is represented as extended over the top of the inclosing case a section through one-half of the prising part of the raceway.

employed to confine the raceway containing the thread-receiver in its working position on a ring-rail of the spinning-frame.

Figure 1 shows part of a spinning or twisting frame with my novel ring sustainedl on 5o the ring-rail. Fig. 2 is an enlarged plan view of the ring resting on a ring-rail. Fig. Sis a section in the line w, Fig. 2. Fig. L shows the thread-receiver detached, and Fig. 5 shows block oom- Referring to the drawings, A represents a suiicient portion of astep-rail havinga bearing a, which may be of any usual or suitable construction,to receive the pintle or'lower end 60 of a spindle, it being my intention to use any of the modern bolsters or bearings to sustain high-speed spindles. The spindle O (partially shown) is of the class known as sleeve-whirl spindles, the blade of the spindle carrying a bobbin O. The ring-rail about each spindleopening therein sustains an inclosing case Yor raceway-holder` shown as made in two parts bb, the part t having 'an inturned iange'2 and an outturned foot 3, while the part b has two upright lips b* 115, the lip 65 being the shorter. l

The raceway of the ring (designated by D) comprises a block having an upright annular wall Z2 lips OZ d', one wider than the other, and a ring-` shaped part d3, of less height than theupright lip Z2 and a little higher, preferably, than the lip 55, said ring-shaped part constituting the inner wall of the raceway. .The 8O space Z4 between the upright lip d2 and the 4ring da constitutes the raceway-space, which is in communication with an annular groove d5, open toward the bobbin. A

The space Z4 receives the body e of the 85 thread-receiver E, (see Fig. 4,) said body having an arm e extended outwardly through Ithe groove d5, where it has an eye'e2 for the reception of the thread t, led from the usual guide-eye t to thebobb and two horizontal inwardly-directed in. The free end of 490y the arm e' is bent outwardly and is made to overlie but not touch the top fiange b2 of the outer member of the inclosing case.

The inclosing case will be connected with the ring-rail in any usual way, springs la being herein shown as standing in notches in the foot b3 and entering the ring-rail.

The thread in the eye e2 of the thread-receiver and being spun or twisted by the rotation of the spindle and bobbin and being wound on the bobbin drags the thread-receiver at a very rapid rate in the space of the raceway, and as the raceway is composed of substantially frictionless material, as stated, there is no possibility of said thread-receiver sticking or binding in the raceway due to friction, and consequently the raceway and the threadreceiver may be run for a very long time and at an excessively rapid rate without undue wear. The. parts of the raceway may be removed when desired and said parts be substituted by others.

I prefer to use as the antifriction material wood treated as now commonly practiced in the manufacture therefrom of antifrictionbearings and the like. There are numerous ways of treating wood to make it durable and render the wood substantially frictionless, and any of these forms may be used in the treatment of wood for the production of raceways.

The body e of the thread-receiver in its rapid rotations contacts with the inner side of the outer wall d2 of the raceway, and said wall limits the extent of outward movement of said thread-receiver due to centrifugal action, the inner side of the ring Z3 of said raceway con. stitutingameans to restrain the inward movement of the thread-receiver toward the bobbin due to variations in tension of the thread being laid or wound on the bobbin.

My invention, comprising a raceway of nonmetallic or frictionless material having an open groove at its inner side in which the threa'd-receiver may be run rapidly, is not limited to the particular shape shown for the different parts of the raceway, and while I prefer to makethe top flange d', the lower flange d, and the connecting portion Z2 integral or in one piece, yet this invention is not limited to making the same in one piece, and the raceway might be composed of separate rings secured one to the other. So, also, my invention is not limited to the exact shape shown in cross-section of the body of the thread-receiver or traveler nor to the exact shape shown for the arm connected with said body and with which the thread to be spun or wound on the bobbin is connected, and it will be obvious that variations in shape may be made in said body and arm and yet be within the scope of my invention herein set forth in the specification and embodied in the claims at the end thereof.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A spinning-ring comprising a raceway having' an annular groove presenting a slot at its inner side, a thread-receiver embraced by said raceway and having a thread-receiving arm extended outwardly through said slot, and an inclosing case for said raceway.

2. A spinning-ring comprising a raceway having an annular groove, a thread-receiver movable therein, and a multipart holder embracing the raceway and adapted to conine the raceway in operative position.

3. A spinning-ring comprising a raceway having an annular groove open at its inner side next the spindle, a thread-receiver having an arm extended through the said open inner side through said groove at the inner side of said raceway and provided with an eye to receive the thread, and an inclosing case for the raceway.

4. A spinning-ring comprising a non-metallic raceway having an annular groove open at its inner side, a thread-receiver free to travel in said groove and having an arm extended through the opening at the inner side of said raceway, said arm being bent to form a threadreceiving eye, and means to confine the raceway in its operative position.

5. In a spinning-ring, a raceway presenting outside, bottom and top walls, and a separate ring constituting the inner wall of the raceway.

6. In a spinning-ring, a raceway presenting outside, bottom and top walls, a separate ring constituting the inner wall of the raceway, a thread-receiver movable between said walls, and means to confine the raceway in working position.

7. A spinning-ring comprising a raceway, presenting an annular box having at its interior an annular groove and presenting three integral walls surrounding said groove, and a ring itted to the inner circular edge of said raceway and constituting an inner wall, said ring being of a height to leave a space between its edge and the upper side of the under wall referred to, and a thread-receiver movable in said raceway, and means for confining said raceway in working position.

8. A spinning-ring comprising a multipart raceway presenting an annular groove, a thread-receiver retained loosely therein, and restrained as to its outward movement under centrifugal action by the outer wall of the raceway and as to the extent of its movement toward the spindle by the inner wall of the raceway.

9. A spinning-ring presenting a metallic inclosing case, a non-metallic raceway therein having an annular groove open at its side next the spindle, and a revoluble thread-receiver therein comprising a body having an arm pro- IIO vided With an eye, the nonmetallic Walls of the raceway preventingan;T part of the threadreceiver from contacting With said inclosing v CaSe.

l0. The combination With a multipart inclosing case, and an inner non-metallierace- Way presenting an open' groove toward the spindle, of a thread-receiver guided by said raceway and presenting an arm between said raceway and spindle for the'reception of the I0 thread being spun and wound.

In testimony whereof l have signed my name t0 this specieation in the presence of twosubscribing witnesses.
