3 Claims. (Cl. 57-133) This invention relates generally to textile apparatus and is more particularly concernedwith a novel spindle assembly for use on spinning frames or the like. I

Spindle assemblies are generally utilized in various stages of the manufacture of various textile fibers into yarns. Conventional spindle assemblies are generally difficult to adjust relative to a base rail upon which they are mounted, it being necessary to have the longitudinal axis of a spindle assembly normal or in plumb relative to the upper surface of a supporting base rail. Additionally, conventional spindle assemblies due to constant rotation re quire constant replacement and repair, fail to include means for adjusting for wear of the various moving parts, and generally require daily oiling of the bearing structure. At present advised, conventional spindle assemblies have a tendency to soil the yarn, for example, being wound on said spindle assemblies by throwing excess oil means for readily adjusting the normal relationship of the longitudinal axis of the spindle assembly relative to a supporting base rail, said improved spindle assembly incorporating an integral oil reservoir utilized as the means for retaining the spindle assembly in fixed relationship on a base rail, oiling the spindle assembly during rotation obviating to a substantial degree the necessity for periodic oiling of the spindle assembly and maintaining the soiling of yarn wound upon the spindle assembly to a minimum.

Other objects of invention in conformance with that set forth reside in the specific details of the cooperating structure providing the various adjusting means for the novel spindle assembly.

And yet a still further object of invention in conformance with that set forth is to provide an improved spindle assembly of the character involved which is readily and economically manufactured, easily installed and maintained, and highly satisfactory and practical for the purpose intended.

These together with other objects and advantages which will subsequently become apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming a 'part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a perspective view of the novel spindle assembly, showing the same mounted on a horizontally disposed fragmentary portion of a base rail of a spinning frame or the like; I

Figure 2 is an enlarged section taken substantially on the plane of line 2--2 of Figure 1; and

2,835,104 Patented May 20, 1958 Figure 3 is an exploded perspective view of the improved spindle assembly.

Referring to the drawing in detail, indicated generally at 10 is a fragmentary portion of a horizontally disposed base rail of a spinning or twisting frame of textile apparatus, said base rail having extending transversely therethrough an aperture portion 12, see Figure 2, the upper surface 14 thereof being normally disposed in a horizontal position. Mounted in the aperture portion 12 of the base rail is a spindle assembly indicated generally at 16.

The spindle assembly 16 includes a mounting member or base piece indicated generally at 18, an oil reservoir 20 and a spindle indicated generally at 22.

The base piece-or mounting member 18 comprises a tubular body member 24 of any suitable material including an intermediate annular shoulder portion 26 engageable on the upper surface 14 of the base rail, the lower end of said body member 24 being externally threaded as indicated at 28, the upper end of the body member 24 terminating in a reduced diameter neck or sleeve portion 30 which has an arcuate concave outer surface 32. The body member 24 has extending longitudinally therethrough a bore portion 34 opening into its lower end, said bore portion 34 continuing as a reduced diameter bore portion 36 opening into the upper end of the body member 24. The juncture between the sleeve 30 and the body member 24 is undercut as indicated at 38. Circumposed about the sleeve 30 -is the inner race of the ring bearing indicated generally at 40.

The spindle 22 includes an elongated spindle shaft 42 having circumposed by means of a press fit, for example, a tubular steel cap 44. Circumposed in suitably secured relationship about an intermediate portion of the shaft 42 is a bushing element 46. The shaft 42 extends through the

bore portions

36 and 34 terminating within the interior'of the oil reservoir 20. Circumposed about the shaft 42 by means of a press fit, for example, on the cap 44 and bushing element 46 is an adapter sleeve or shaft 48. The sleeve 4? at bushing element 46 has a tubular sleeve portion 50 of an adapter 52, said adapter 52 including an increased diameter annular skirt portion 54. Circumposed about the skirt 54 is an annular sleeve or flange 56 of a sleeve pulley 58 about which an intermediate portion of a drive belt will be entrained. The inner periphery 60 of the pulley is disposed in spaced relationship from the outer periphery of the body member 24. The diameter of the shaft 42 is less than the diameter of the bore portion 36 through the body member 24. The bearing assembly 40 cooperating with the outer arcuate surface of sleeve 30 will permit relative angular movement of the spindle 22 about the base piece 18 for the purpose of maintaining the longitudinal axis of the spindle normal to the upper surface 14 of the base rail 10. Although specific structure has been disclosed for accomplishing for the adjustment of plumbing the longitudinal axis of the spindle relative to the base rail, the bearing assembly 40 may be constructed with sufficient loss motion between the inner and outer races thereof to permit the adjustment of the spindle 22 about a 360 degree plane as indicated by the arcuate direction arrows in Figure 2 relative to the upper end of the base piece 18, and the outer periphery of the shaft 42 relative to the inner periphery of the bore portion 36. The undercut portion 38 will permit relative movement of the bearing assembly 40 relative to the sleeve 30 of the base piece 18.

The oil reservoir 20 comprises a cylindrical hollow body member 62 including a transverse upper wall 64 having a transverse centrally located threaded aperture 66 therethrough for receiving the lower threaded end 28 of the base piece 18 therein and engaging the lower surface .6 'Of new. a l a id. s rdis lrr ta n es t zeaaiasi A assembly on saidbase rail. Suitable oil will be contained within the hollow interior 70 of the body member 62.

duced diameter externally threaded shoulder por tion .-f72. An annular cl arnping collar 74 incorporates an nternally threadedf s houlder portion 72 of the body member, said clamping collar 74 incorporating an end portion 78 having atransverse central aperture 80 therethrough. An annular inachined sealing member 82 is clampingly engaged between the inner surface 84 of the end portion 78'of collar 74 and the lower edge 86 of body mem er 62 fine 'sealing'member 82 is of a smaller diameter than theinner periphery of the collar 74 and incorporates, an annular spake 88 about its outer periphery. Member 82 includes a shoulder portion 90 having a diameter lessthanthat of ,.the diameter ofthe' hollow interior of body member 62.

j The sealing member 82 incorporates a centrally loc ated transverse internally threaded aperture portion 92 An elongated externally threaded adjusting screw 94 extends through the threaded aperture 92, incorporating in its lower end' a recess portion 96 for accommodating therein ."the end of an Allen wrench. Circumposed about the adjusting screw 94 below the sealing element 82and engageable therewith is a suitable lock nut 98 which may iibe rotated by means of any suitable wrench for maintaining the screw in a relatively fixed position of adjustment relative to the sealing element 82. v 4 I The upper end of the adjustingscrew 94 incorporates a :l ongifudinal blind bore portion 100 having extending longitudinally through opposite sides'thereof slot portions 102. Received within the bore portion 100 is a cylindrical bearing element 104 incorporating a transverse bore portion 186 therethrough, said bore portion 106 communicating with'the slot portions 102. The bearing element 104 incorporates an upwardly opening bore portion 108 in communicationwith the transverse bore portion 106 and receiving therein thelower end 110 of the spindle shaft 42. The bore portion 186 in communication with the slot Q portions 102 permit communication of oil containedwithin the reservoir to the lower end 110 of the shaft 42. I

p In operation, the spindle 22 may be aligned with or plumbed with respect to the base rail 10. One way would be to loosen the reservoir 20, this loosening enabling the body member 24 to beshifted horizontally and vertically in the aperture portion 12 in the base rail 10.
