/t l This invention relates to improvements in spinning and twisting rings employed in the textile industry to support and/or guide a travelerv for revolving movement thereabout.

As is well known, the traveler moves around the'spinner or twister at a relatively high speed and the contacting surfaces, particularly those of the traveler, will readily wear away unless properly lubricated. Lubricant supplied to the ring should be uniformly distributed to the surfaces thereof engaged by the traveler and should be confined to the ring.

An object ofi thesinvention is the provision of a spinner or twister ring in which lubricant is uniformly supplied to all surfaces thereof engaged by the traveler; and to provide an assembly wherein such ring is so isolated from its support that lubricant supplied to the ring is effectively confined thereto and cannot gain access to other portions of the assembly including the sup-` port.

,In carrying out the lubricant by capillary actionand to exude the same at the surfaces of the ring; and there is provided a seal between the ring and support which prevents the transmission of lubricant therebetweenand serves as a means for mounting the ring on its support. The combined seal and mounting is impervious to lubricant, will not appreciably deteriorate in the presence thereof, and preferably should have an inherent resiliency which will facilitate sealing engagement in response to a compressive force. More specically, the same may be formed from a material having the characteristics of rubber.

A.further object of the invention is the provision of a seal between the spinner or twister ring and its support which prevents the movement of lubricant therebetween and which also functions in conjunction with the ring to provide an open reservoir with a part of the ring at the bottom of the latter adapted to receive lubricant.-

for transmission by capillary action'to those surfaces of the ring engaged by the traveler.

Other objects and advantages of the invention will be more apparent from the following description taken in connection with the accompanying drawings, in which:

Fig. 1 is a diammetrical section of a ring and rail assembly embodying the invention. f

. Fig. 2 is a top plan view of the ring shown in Fig. l. f

Referring to the drawings, a ring rail of a spinning or twisting frame as employed in the foregoing the spinner orV twister ring has a porosity sumcien't to transmit 6 Claims. (Cl. 57-120) textile industry is indicated -by the numeral 6,

such rail having one or more openings therein for the reception of a ring 6. The invention is appli- `cable to veither spinning or twisting rings and the s ame are hereinafter referred to in a generic sense as a spinner ring orrrings.

Each opening in the ring rail '5 includes a radially ,inwardly extending flange 'I` and lis bounded by an annular axially extending wall 8, an annular radially extending wall 9 and a second annular axially extending wail I0 at the free end of the flange 'I. The ring 6 includes a main body part I I and an annular'radially outwardly ex,-

.tending flange I2 disposed in overlapping relationship with the flange 'I. While I have shownl the ring 6 mount d directly in the opening of the rail 5, nevertheessJ if desired the ring may be mounted in an adaptor or holder in the same manner as shown for the'direct mounting and such holder or adaptor may be bolted or otherwise secured to the rail. The ring is thus supported directly from the rail or indirectly therefrom when either adaptoror holder is used.

The ring `li guides a traveler I3 for relatively high speed revolving movement thereabout, the traveler being of the type which hooks over and engages the upper and lower edges of the ring 5.

.When employed as particularly illustrated the ring, serves to impart a twist to a plurality of strands I4, the twisted strands i5 being wound onto a' rotating spool i6. It is desirable to minimize the friction between the traveler i3 and the surfaces of the ring 6 engaged thereby and for this purpose lubricant should be supplied to such surfaces in quantity sufficient to prevent frictional wear, especially'of the traveler.

With the foregoing in mind, the ring 6 is preferably formed from a mass of sintered metallic particles and has a degree of porosity sufficient to absorb lubricant and to transmit the same by capillary action. In general, the metallic particles are briquetted under relatively high pressure to produce a ring of substantially the desired shape and dimensions and the briquette is then sintered in a non-oxidizing atmosphere to cause the particles to adhere together and thus provide a relatively high strength porous body. The porosity may be varied by varying the size and shape of the particles and by varying the briquetting pressure. The ring may be hardened.

particularly at those surfaces thereof engaged by the traveler, by any well known method or process, for example by nitriting.

While I prefer to-use ferrous metal particles. either alone or in combination with copper or tin particles, nevertheless other metals or combinations thereof, such as copper and tin may be used. For example, a mixture of 90 parts iron and parts copper or tin by weight is suitable for the purpose intended or a mixture of 90 parts copper and 10 parts tin by weight may be employed.

With the ring 6 as shown, lubricant may be supplied to the flange I2 and transmitted therefrom by capillary action to the main body II, and particularly the surfaces at the upper and lower edges thereof which are engaged by the traveler I3. In order to isolate the ring 6 and its lubricant content from the support, there is provided a seal, generally indicated by the numeral Il, having a radial flange I8 extending between the ring ilange I2 and the rail flange Il, and an axial flange I8 extending between the outer peripheral edge of the ring flange I2 and the rail wall 8. As shown the end face of the flange 1 is radially spaced from the main body II of the ring 6 to permit the traveler to move therebetween and the seal flange I8 bridges such space and abuts the outer periphery of the body Il above that portion of the latter which Is engaged by the traveler.

The flange I9 cooperates with that part of the main body II of the ring to form an annular lubricant reservoir, the bottom wall of which is provided in part by the ring flange, A plurality of retainers '20, each secured to the ring rail 5 by a screw -2I, extend into this reservoir and engage the ring flange I2 to-press the latter flrmly against the seal flange I8. Lubricant can be dropped into this reservoir during operation of the mechanism and the seal will prevent leakage or drippage of the lubricant from the reservoir to the mechanism therebelow. Oil applied at ,the flange I2 will be exuded at a relatively low rate to the peripheral surface of the main body of the ring,

In addition to functioning as a lubricant seal, the seal Il serves as a means for resiliently mounting the ring 6 on its support and will minimize the transmission of vibrations therebetween which may be developed by revolving movement of the traveler about the ring 6 and vertical reciprocal movement of the latter and the ring rail support 5.

Although but one specific embodiment of the invention has herein been shown and described,

' it will be understood that various changes in the size, shape, and arrangement of parts may be made without departing from the spirit of the invention.
