To @ZZ whom/- imcty coincer-'72,:

Be it knownthat I, GEORGE O. DRAPER, a citizen of the United States, and a resident of Hopedale, county of Worcester, and State of 5 Massachusetts, have `invented an Improvement in Yarn-Spinning Apparatus, of which the following description, inconnection with the accompanying drawings, is a specification, like letters on the drawings represent- 1o ing like parts. v

My invention relates to ring-spinning apparatus wherein the ring is rotatably mounted on the ring-rail of the frame, the pull of the yarn on the traveler, which latter Iis'revoluble on the ring, finally overcoming the inertia of the ring and. causing the ring itself `to rotate at Ver'y high speed, the ring at such time appearing to the eye to ioat in the air.

In my present invention I have provided zo the ring with an overhanginglint-guard, and in order to limit the upward movement ofthe ring I have provided a plurality of stops, which areextended through radial recesses in the annular ring-seat to engage the ring z5 beneath the lint-guard. The latter thus protects the limiting means, so that there is little or no opportunity forlint to collect thereupon.

Figure l is aview in side elevation and 3o section of a portion of a ring-rail witha ringspinning device embodying one form ot my invention applied thereto, the spindle and. bobbin being partly shown in dotted lines. Fig. 2 is a top or plan view ot' the ring seat or support, and Fig. 3 is a side elevation of the ring illustrated in Fig. l.

I have herein shownonly the part of a ringspinning apparatus which immediately cooperates with my invention-viz., the ring- 40 railas any well-known or usual ring-spinning frame and its appurtenances can be used in connection with myinvention.

Referring to Fig. 1, the ring-rail R, having the aperture R for the lpassage of the spindleS or bobbin B therethrough, has in the present embodiment of my invention an annular ring seat or dsupport a, attached thereto by suitable headed screws s, which pass through holes ct in the bottom ot' preferably 5o diametrically-located ears a2, extended be- 0. Serial No. 34,421. (No model.)

yond theperiphery of the seat. The ring itself comprises a top .or head b, which is laterally extended at its periphery to present an ot''erhangiug projection or liange b', which forms the top of an annular external recess b2 in the body or web b3 of the ring, the formation of the recess leaving a projection or rib b4 at or near the lower end of the web. This lower projection b4 is of less external diameter than the iiange b', as is clearly 6o shown in Figs'. l and 3, and. enters the ringseat, va slight clearance being permitted between them, so that the ring may have a limited radial movement as well as free rotative and axial movement. The ange b' 65 overhangs the ring-seat and rests upon the top thereof when thevring is at rest, as in Fig.

1, the ring having a suitable traveling race bx for a traveler pf any suitable construction, the race herein-shown being vertical. holding-screws s are herein shown as extended through fiat plates or stops d of any suit- .able material-such as ber, leather-board,

Kre-which project into the annular recess b2 ofthe ring beneath the overhanging flange b', 75 the vertical height of the recess being greater than the thickness of the stops, permitting a limited vertical movement of the ring under the stress of the yarn. The projection b4 below the stops limits the upward movement of 8o the ring, and it will be manifest that the cooperating parts of the latter and the stops d are protected from lint or dust by the overhanging flange b', which thus constitutes a lint-guard.

By the construction shown the top of the ring offers nothing to catch or collect lint or dust, and owing to the hidden or concealed locationof the operating portions of the stops access of lint thereto is practically prevented. 9o The stops are'shown as resting upon cushions or pads dx, of felt, rubber, or other preferably-yielding material to preventy shock, the cushions being held in the ears ag'o't' the ringseat, said ears being preferably vmadeboX-like 9 5 or socketed to hold'thecushion`s',the latter having a radial recess ctx'therein opposite each ear to permit the passagetheret'hrough of the stop d and below the annular top face of the seat.

The 7o IOC ble ring axially movable relatively to the seat., 15 and having an external annular groove, a limitingstop secured to each ear of the seat and extended through the annular recess of the ring, and a lint-guard on the latter overhanging the ring-recess.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.

GEORGE O. DRAPER.
