A pplication filed. January 15, 1924.- Serial No. 686,521.
To all whom it may concern:
Be it known that I, ALoNzo E. Rnonnns, a citizen ofv the United States, resid ng at Hopedale, in the county of Worcester and 1 State of hiiassachusettahave invented air in Lay-Rock-Shaft Bearings, following description, in connection with the accompanying drawings, is a specification, like characters on the draw: ings representing like parts. V
This invention relates to looms and more particularly to the lay rock-shaft bearings.
The constant rocking movement of the lay rock-shaft during weaving produces lli'nprovement wear upon the bearing and'l'ost motion be tween the operating parts which in time causes the path of the lay to assume a position different from its originally intended path and subjects the parts to play resulting in imperfect weaving.
l-leretofore various expedientshave been suggested for relieving the rock-shaft from wear, and the present invention relates to a construction in which the shaft supporting bearings do not come in actual contact with. the rocking shaft so that the shaft itself is not subjected to wear. 4 v
The present invention is directed to a simple bearing construction which is'inexpensive to'i'nanufactinfe and which may be readily adjusted from time to time to take up wear between the parts.
The invention will best be understood from the following description and accompanying drawings of one good practical form thereof. 7 I V In the drawings a Fig. 1 isa perspective view ofthe lower portion of the loom frame showing a lay rock-shaft provided with the bearing ofthe present invention. I Fig. 2 is a sectional view through the lay rock-shaft and looking toward the bearing of Fig. 1.
Fig. 3 is a sectional. view taken on the line 7 3-3 of Fig. 2. V
Fig. 4 is a sectional view taken on the line a e. of Fig. 3; and
Fig. 5 is a vertical sectional view through the bearing.
The loom frame 1 may be of usual construction and comprises the usual side memhers having a web 2 provided with an enlarged opening 3 adapted to receive the bearing hub to be described, and the rockthe bushing sired position of adjustment. To this end shaft 4 is provided with the lay swords .5 which may are rigi lly secured to the shaft 4.
j t is obvious that should the lay rockshaft 4 become badly'worn it cannot be replaced readily, and the present invention thereroreconten'iplates a bearing construction consisting of inexpensive parts that relieve the shaft from wear, and which may be readily adjusted to take up wear, or may i be easily renewed without disassemblingthe loom.
in the construction shown the bearing consists of a hub 6 that projects into the opening 3 formed in the 100m frame and the hub 6 preferably is provided with opposite ly extending side or wing portions 7 and 8 which may be rigidly secured to the web 2 by bolts 9 passing through the wing portions vand web, and the hub may be further secured in place by the pins 10. vThe hub 6 has a tapered bore adapted to receive a bushing 11 mounted upon the shaft 4: and having, its outer surface tapered to fitthe tapered bore of the hub. The bushing 11 is rigidly secured to the rock-shaft 4 by means to be described so that asthe lay rocks back and forth the bushing 11 will rotate in the hub 6 and as the parts become worn the tapered bushing may be moved further into the hub to take up wear, or it may be rotated angularly to bringa different portion of the bushing below the shaft where the greatestwear occurs.
It is desirable to provide means for preventing the rock-shaft from moving in the direction of its length and also to secure 11 to the rock-shaft in the dein the construction shown a collar 12 is provided mounted upon a protruding portion of the bushing 11 in position to abut against the outer end of the hub 6, and the collar 12 is rigidly secured to the shaft 4: in the desired position by a setscrew 13 which extends through a clearance slot 14 in the bushing and engages the rock-shaft. The collar 12 is also preferably provided with a set screw 15 that rigidly secures the collar to the bushing.
As a result of this construction the bushing 11 may .be'moved to the desired position of adjustment within the hub 6, and then the collar 12 may be adjusted lengthwise of the rock-shaft 4 until its inner face rests be of usual construction and III against the endof the hub 6. The parts may then be secured rigidly'in this position by 5, due to the weight of the parts and the rocking movement of the lay .shaft," and when it is desirable to make adjustment to' may be readily 'i' loosening. theset screw 13 so 7 that the bushing 11 with the collar l2 thereto by the set-screw 1b compensate for wear, this done by simply rigidly secured 4 may be rotated to bring a different portionof the bushing to the lowermost position. Or. if desired both setsorews 13and 15 may be backed off moved further into the hub 6 .to take up the play. In this manner the bearings may adjusted to take up wear without which is rigidly secured upon the projecting end; ofthe rock-shaift by a set screw 19, and the inner end of the sleeve 18 may enter the recess 20 formed within thexcollarl Oil may be suppliedto the bearing.
