To @ZZ whom, t may concern- Be it known that I, JOHN C. EDWARDS, a citizen of theUnited States, and a resident of Brookline, county of Norfolk, State of Massachusetts, have invented an Improvementin Yarn-Spinning Apparatus, of which the following description, in connection with the accompanying drawings, is a speciiicatiou,

Vlike'letters on the drawings representing like parts. Y

My invention relates to that type of yarnspinning apparatus wherein the .ring is revolubly mounted on the ring-rail, the ring being rotated with the traveler after the spinbe hereinafter fully described, and particu-A -larly pointed out in the following claims.

Figure l is a diametral sectional view of a portion of a spinning apparatus embodying one form of my invention, the ring-rail being shown in section. Fig. la is a perspective detail of a part of the buier. shown in Fig. l. Fig. 2 is a. sectional view of another embodiment of my invention, the bader being made apart of the ring. A l Fig. 3 is a sectionaldetail of another modification to be described. Fig. 4 is a top or plan view of a part of the construction shown in Fig. 3. Fig. 5 is a sectional detail similar to Fig. l, but with a different form of buffer; and Fig. 6 is a perspective detail of a part of the bader shown Referring first to Fig. l, the ring-rail A, of sheet metal, is provided with the usual cir- I.cular spindle-aperture A, andthe ring B, co- 45 operating therewith, is shown as having a flanged head b for the traveler t, of usual construction. The .web of the ring is shown as `provided with a depending base b, which extends ,freely into the spindle-aperture, said base being bent to present an external annular recess or seat b2. i A yielding annular buffer c is mounted in the seat between thering-base and the edge of the aperture A in the rail, and in vFigs'. l and la theibuffer is shown as a spring-coil convex on its inner circumference to rest in the seat b2 and havingr the turns of thespiral bent in or concaved along the outer circumference to present two series of projecting portions c' c?, which straddle the edge of the aperture A. The curvature ofthe seat b2 is slightly greater than the curvar ure of the adjacent part of the buffer (see Fig. l) to permit a limited vertical or axial play of the ring and also to permit some radial movement thereof. When the spindle is speeded up, the pull ofthe yarn on the traveler will rotate the ring, and its axial and radial movements are limited in a yieldingmanner by the butter, which latter also maintains the ring in operative position relative to the rail.

In assembling the parts the huler is inverted in the spindle-aperture of the rail, and the base ofthe ring is then pushed into place within lthe buer, the latter yielding to permit it.

Referring to Fig. 5, the base d of the ring D is.,provided with an annular recess d to receive the buffer d2, which is in this instance made as a band ofl corrugated spring metal, alternate bends being punched, as atds, to leave projections d4 d5, which extend above and below the rail, respectively. Aclearance 4 is left between the loweredge of the buffer andthe external lip or liange 5 pf the ringbase, which forms the bottom of the external recess d', permitting limited axial movement of the ring under the strain of the yarn.

In Fig. 2 I have shown the buier formed as a part ot' the ring itself, and for this pur. pose the web f of the ring has a depending portion f', concave-convex in cross-section and made thin and having several slits or notches fx extended thereinto upward from its lower outturned edge f2. I prefer to provide an external rib or annular projection f3 .at the to p of the notched portion f', of greater diameter than that of the spindle-aperture A' of thering-rail, land normally the edge f2 is of greater diameter than the aperture A. To assemble the ring and rail, the buler` portion f' of the former is compressed sufficiently to permit the edge j2 to pass through the spin'- xoo l spinning@ when the ringis revolving, the edge f2 limits its vert-ical or axial movement, while the clearance between the edge of the spindleaperture and the conca-ved portion of lthe buffer perinits radial movement of the ring.

Referring to Figs. 3 and 4, theV ring` B is of I, substantially the construction-shown in Fig.

1, its external annular recess or seat b2. re-

spring or c'oil fm; but theoutercircumference of the butler isv shown as seated in an annu- Alar concaved holder-7L, having atl its top a laterally-extended flange h', which is secured to the rail A by lsuitable screws hx, the buffer beingr located below the upper surface of' the rail'. -By this' arrangement small vrings can be used with :rails having large spindlejaperture's, and as the curvature ot' .the'recess .portions of the buti'er and ring.

bfi is greater than that of the buer provision is made foraxial and'radial movement of the ring under the `stress of the yarn, .while such movements are limited by the cooperating The lower lip h2 of the holder extends beneath the buffer far enough to support the latter in an effective manner.

IMy invention' is not restricted to the prev'oise construction and arrangement. shown, as

the same may be modified or rearranged without departing from the spirit and scope of .my invent ion. y

'aperture and means to cooperateA edge-ofthe aperture and limit the radial and Having described my invention, -what I `claim as new, and desire to secure by Letters Patent, isd Y l. The combination with the ring-rail having a circular spindle-aperture, of a revoluble ring movable radially and axially under the stress of the yarn and extendedinto said aperture, and ayielding means to retain the ring `.i operative position.

2. The oombinationwith the ring-rail heving: a circular Spindle-aperture, of a revoluble lring vfreely movable under unbalanced strains' and having its base extended into the with the axial movements of the rinof.

' 3. The combination with the ring-rail having a circular spindle-aperture, and a revoluble ring having a traveler-race and a base depending below the top of the. rail, ot yielding means'interposed between the ring and the rail to limit movement. of the ring u nder un balanced strains of the yarn.

4. The combination withthe ring-rail hav'- ing a circular spindle-apertore, of a ring having an external annular recess in its lower portion, and yielding means cooperating with the rail and the recessed` portion of the ring to retain the latter in operative position.

5. A'l'sheetme'tal ring-rail havin;T acircular spindleapcrl u re, a revoluble ring: capable of radial movement, and au annular yielding` buffer interposed between the ringand the edge of the aperture'in-the rail to limit radial movements of the ring.

"6. Asheet-meta-l ring-rail haringaoireular spindle-aperture, a revoluble ring capable of 'yielding buler interposed between the ring axial movement of the ring.

7. A sheetmetal ring-rail having` a-c'irc-ular spindle-aperture, a reroluble ring capable of radial movement and having an annular seat, and a spring mounted iu said seat and in en gagement with the edge of the spindle-aperture.

8. A sheet-metal ri 11g-rail having a circular spindle-aperture, a revoluble ring capable of axial and radial movement and havingan annular, external recess", and a spring,r seated in said recess and havingr peripheral projections extended above and below the edge of the spindle-apertureto limit the axial movement of the ring. y

9. A sheetxnetal ring-rail having a circular spindle-aperture, a revoluble ring, and yielding annularmeans coperati of the spindleaperture*and connecting the ring operatively with the rail.

In testimony whereof I have signed my two subscribing witnesses.
