permit a certain amount'of yielding on the part' of the ring under operating conditions and at the same time act as a dampener to reduce vibration and noise. A further object is to provide 6 Claims. (01. 51-122) reception of each such ring 2 the rail is formed with a circular opening 4 of somewhat larger Gil a mounting which will permit of the ready placement of a ring in the supporting member without requiring the use of any tool, while at the same time a firm and secure mounting is provided for said ring under operative conditions.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully describd and particularly pointed out in the claims;

The annexed drawing and the following de scription set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the, principle of the invention may be used.

In said annexed drawing:

Fig. 1 is a plan view of a typical spinning ring shown as supported by our present improved mounting in a ring rail; I

Fig. 2 is a transverse section of the foregoing, the plane of the section being indicated by the line 22, Fig. 1; V

Fig. 3 is a sectional view on a larger scale of ring and the mounting therefor; and.

Fig. 4 is a sectional view similar to Fig. 3 but showing a modification in construction.

The ring rail i, as shown in Figs. 1 and 2, is

of usual construction, consisting of a channelform member. pressed from sheet metal and of diameter than the exterior diameter of the ring body although the latter may have a radially projecting flange I of the same or slightly larger diameter than such opening. In addition, the body of said ring is formed with an encircling groove 6 located in spaced relation below suc For the purpose of mounting the ring in the opening in the ring rail a grommet or gasket 1 of special cross-sectional form, as will now be described, is provided, such grommet being composed of resilient material, e. g. ofrubber, either natural or synthetic, vulcanized to the desired degree, or of equivalent resilient, compressible,

material. This grommet is interposed between the outer face of the ring body and the edge of the opening l in the ring rail and constitutes the sole connecting means between the two parts in question. As best shown in Fig. 3, said grommet is formed with an inwardly directed rib 8 that is adapted to seat in the recess 6 in the ring body and with a peripheral groove 9 that is adapted to engage the. edge of the opening 4 in the ring rail. While such groove is formed so as to em brace such edge more or less closely, the rib l I on the grommet in the construction under con-;

sideration is of less depth, or cross-sectional area, than recess-i. The latter, it will be noted, is

placed andthe corresponding edge of the recess in the grommet may be slightly rounded as shown in Fig. 3.

ways 3 whereon the spinning or twisting device (not illustrated) is rotatably supported. For the In the assembled condition of the parts the rib or flange I on the body of the ring rests on the upper face of the grommet and such ring is additionally held in place relative to the grommet by the'engagement between recess 6 therein with the inwardly directed rib I on the grommet.

' Finally, the latter is secured in place by engage-- ment of the peripheral groove in its'outer face with the edge. of the opening in the ring rail; However, due to the resilient, compressible, characterof said grommet, upon forceful movement of'the ring in a downward direction axially of such opening a portion of the grommet adjacent rib l'tliereon will be squeezed into the space normally remaining between such' rib and the bottom of groove tin the ring. This space will be 'sufllcient'to accommodate the volume of such displaced material and the. latter will be'sufflcient to permit the grommet to slide past the radially outwardly sufilciently to disengage it from the ring, if desired.

In the modified construction illustrated in Fig.

4 the ring rail i and ring 2 are of substantially the same construction as that described above,

the only difference being that the peripheral groove iii in the body oi the ring is curved at its bottom instead of being of rectangular cross-sec in such an opening. Thus said ring, and the opening wherein it is mounted, may be of other than circular form and be designed for other use than to support a spinning or twisting device.

tion. Likewise, the grommet ii is of substantially the same construction as gasket 1 except that the rib l2 thereon, which is designed to engage such groove I0, is of substantially the same conformation so as to completely fill the latter. -'Also the outer face of the grommet in which is formed a groove I! designed to engage the edge of the opening 4 in the ring rail more closely engages both sides of the latter adiacent such opening than in the case of grommet I. Finally, said grommet is iormed on its inner face immediately below rib I! with an inwardly directed encircling groove M.

In the assembled condition of the parts the grommet ii obviously will function in identically the same way as grommet I to support the ring 1 in the opening in the ring rail. when it is desired to remove the ring, pressure is' applied thereto as before. and the portion oI the grommet adjacent such last-mentioned groove ll will be compressed and displaced to a suiiicient extent to permit the groove 13 in such grommet to be dis engaged from the edge of opening 4 in the ring rail. and displacement of such portion of the grommet the latter may be forced downwardly through such opening until the groove in question is again ..rought into engagement with such edge.

It will be understood that in the operation both of removing and thus inserting the ring in place in its mounting the grommet will remain attached thereto by engagement of rib II on the grommet with groove iii in the ring. It will also be noted that the lower outer face of said grommet is beveled or inclined outwardly, which serves to facilitate placement oi the ring, with the grommet carried thereby, in the opening in the supporting member. u

As previously stated, in both of the two illustrative forms of our improved spinning ring mounting the grommet constitutes the sole connecting means between the ring rail or equivalent supporting member, i. e. there is nowhere any metal-to-metal contact between the parts in question. At the sametime. owing to the unique form and construction of the grommet. removal and replacement of the ring may be readily accompllshed without detracting from the security with which it is held in place in the assembled condition of parts.

A} likewise previously remarked, the ring rail i is merely illustrative of a similar supporting member, in an opening in which it is desired to mount a ring. Similarly the term "ring" as used herein is to be understood as eonnoting any equiv- Conversely. by corresponding compression Finally, it should be noted that depending on therelative extent axiallyof the (edge of the opening in the supporting member" and of the juxtaposed outer face of the ring the disposition of grooves and ribs on the grommetmay be reversed.

- Other modes of applying the principle of our invention may be employed instead oi the one explained. change being made as regards the mechanism herein disclosed, provided the means stated by'any, of 'the followingclaims or the equivalent of such stated means be employed.

We therefore particularly point out and distinctly claim as our invention;

1. In mechanism of the character described, the combination with a support having an opening and a ring adapted to be mounted in such opening; of a grommet of resilient material interposed between said ring and the edge of such opening, said ring being formed with an encircling recess and said grommet with an inwardly directed rib adapted to seat in such recess .and with a peripheral groove adapted to engage such edge.

2. In mechanism of the character described, the combination with a support having an opening and a ring adapted to be mounted in such opening, of a grommet of resilient material interposed between said ring and the edge of such openings, said ring being formed with an encircling recess and said grommet with an inwardly directed rib adapted to seat in such recess and with a peripheral groove substantially opposite said rib adapted to engage such edge.

3. In mechanism of the character described, the combination with a support having an opening and a ring adapted to be mounted in such opening, of a grommet of resilient material interposed between said ring and the edge of such opening, an encircling groove being formed in one of the juxtaposed faces of such opening and ring and said grommet being formed with a radially projecting rib adapted to'seat in such recess and with an oppositely-directed groove adapted to engage the other such juxtaposed face.

4. In mechanism of the character described, the combination with a support having an opening and a ring adapted to'be mounted in such opening, of a grommet of resilient material inter posed between said ring and the edge of such opening and constituting the sole connecting means between said parts. said ring being formed with an encircling recess and said grommet with an inwardly directed rib adapted to seat in such recess, the outer face of said grommet below such rib being beveled and such rib not entirely illiing such recess to' permit forcible insertion of said ring and grommet in such opening by deformation or said grommet.
