WHIP-ROLL FOR LOOMS.

Specification of Letters Patent.

Patented Nov. 9,1920.

. Application filed March 19, 1920. Serial No. 367,069.

porting-arms may be readily repaired afterv their bearings have become so worn as to be more or less useless, as more fully hereinafter set forth.

In the drawings Figure 1 is a side elevation of a whip-roll supporting-arm provided with my repairbearing;. i I

Fig. 2 is a plan view thereof;

Fig. 3 is a side elevation of a common form of supporting-arm,as it appears before the bearings are worn.

The whip-roll is shown at a, one of its supporting-arms at b and its oscillating supporting-shaft at 0, these being constructed as usual. One of the arms for supporting the shaft 0 is shown atd, this arm blein of the usual construction except that t e made in accordance with my invention. The usual construction of. this arm at before it is worn is shown in Fig. 3. It will be observed that. it is rovided with two bearing-notches e, e. 11 use, the outer bearing 6 wears away, as shown by dotted line f, thus destroying the utility of the entire arm and requiringthat it be taken off the loom and "discarded and replaced by 'a' new arm. With my invention, I can utilize this arm notwithstanding the fact that the bearing is worn to the extent of becoming useless as a support for the rock-shaft c. In utilizing this worn arm, I mill away the transverse rig g upstanding between the two bearing-notches, this being milled down to the dotted line 71,. I then fit into this widened notch a wooden block i and fas-' arm bored for the s ecial purpose of receiving this. bolt. This locki is provided with a rounded notch k which forms a new bearingffor the rock-shaft c. Inthis rounded caring for supporting the shaft 0 is for receiving a lubricant, and a notch is formed a depression Z which is adapted to be filled with tallow orx some other material which will not onlylubricate the bearing but will wo'rk'into the body of the block and thus render the same virtually selfdubricating. Of course, the tallow deposit is r'enewed from time to time, but,as the wood becomes more and more impreg nated with the tallow', a lesser quantity is re uired for proper lubrication.

ith my invention, it will be obvious that I save the waste heretofore ,involved in junking the worn arms at. As the bearings in these arms wear quite rapidly, this is a very material saving, and particularly because of a fact which I have found from experience, namely, that the new or repair bearing lasts much longer than the original bearing and also results in li hter running of the whip-roll mechanism. The whip-rollshaft 0 of course also becomes worn at the points of impingement against thebearingroll mechanism and also prevent the worndown surfaces of the shaft 0 from cutting the wooden blocks.

The nature and scope of the invention having been thus indicated and its preferred embodiment, having been specifically described, what is claimed as new is:

1. In a whip-roll mechanism for looms. a supporting-arm for the whip-roll-shaft having a widened notch in its upper side a wooden block fitted into this notch, said block being provided with a bearing-notch for receiving the shaft of the whip-roll and said notch being provided with a de ression olt for attaching the block to the arm.

2. In a loom,- a whip-roll-arm provided with a'notch, a wooden block fitted snugly in said notch and provided with a bearingnotch, and means for fastening this'block A in its seat. I

In testimony whereof I hereunto afiix my signature.
