LOOM.

SPECIFICATION forming part of Letters Patent No. 621,138, dated March 14, 1899.

Application filed October 20, 1898. Serial No. 694,096. (No model.)

T0 all whom, it may concer/1,:

Beit known that I, EUGENE RENZ, a citizen of the United States,residing at Stirling, in the county of Morris and State ot' New Jersey, have invented certain new and useful Improvements in Looms, of which the following is a specification.

My invention relates to looms, and vmore particularly to the lay or beating-up mechanism and the dwell-stand intermediate the lay-sword and the crank-shaft connector.

In the class of looms to which my improvements are to be applied the dwell-stand, as it is termed, is rigidly attached at its lower end to the lay-sword and pivotally attached at its upper end to the crank-connector and the lay-sword. When the lay protects to stop the loom, the crank-shaft does not stop immediately, but pushes by means of the crankconnector upon the dwell-stand in an upward direction, and the dwell-stand being rigidly attached to the lay-sword at its lower end cannot yield, and consequently the dwellstand is often broken and sometimes even the lay-sword.

The object of my invention is to provide relief for the lower end of the dwell-stand, so that the upper end of the stand may swing or move on the pivot-pin connecting it with the lay-sword when the lay protects, and thus prevent the breaking of the dwell-stand or of the lay-sword.

My invention consists in certain novel features of construction of the dwell-stand, and more particularly in providing for the yielding or moving of the lower end of the dwellstand, so that the upper end may swing or move on its pivot connection with the lay= sword when the lay protects.

Referring to the drawing, I have shown in the drawing a sectional elevation of portions of a loom of well-known construction and operation with my improvements applied thereto.

In the accompanying drawing, 1 is the loom side or end. 2 is the crank-shaft; 3,the crank connector, and 4 the crank-connector pin, connecting the crank-connector 3 with the rear upper end of the dwell-stand 5. The front upper end of the dwell-stand 5 is pivotally connected with the rear of the lay-sword 7 by the pin 6. The lay-sword 7 carries the lay S, on which is the race-plate 9, and the lay-foot 10 is mounted on the rock-shaft 11.

The protector-rod stand 12 is secured to the lay 8 and carries the protector-finger 13,which 55 is adapted to engage the bunter-lever 14 on the bunter-stand 15, secured to the breast-beam 16 when the lay protects.

All of the above parts are of the ordinary construction and operation in the class of 6o looms to which my improvements may be applied.

In the ordinary construction of the dwellstand 5 the lower end 5 is made a part of or rigidly secured to the lay-sword 7. In my improved construction the lower end 5 of the dwell-stand 5 is not rigidly secured to the lay-sword, but is connected therewith so as to have a movement independent of the laysword to allow the upper forward end of the 7o dwell-stand 5 to swing or move on its pivotpin 6 when the lay protects. In thisinstance I have yieldingly connected the lower end 5 of the dwell-stand 5 of the lay-sword 7 by means of a pin 17, which extends loosely through a hole in the lower end 5 of the dwellstand 5 and through a hole in the lay-sword and is secured to the lay-sword by a setscrew 18.

A washer 19 is loosely mounted on the pin 8o 17 and bears against the inner surface'of the vopening in the lower end 5' of the dwell-stand 5. A spiral compression-spring 2O encircles the pin 17 intermediate Athe washer 19 and the head of the pin 17.

The spring 2O acts to hold the lower end 5' of the dwell-stand 5 against the lay-sword 7 to move with said lay-sword, but also allows the lower end 5 of the dwell-stand 5 to yield and move away from the lay-sword, so that 9o the upper front end of the dwell-stand 5 can swing or move on its pivot-pin 6.

The operation of my improvements will be readily understood by those skilled in the art.

When the lay protects, the protector-finger 13 strikes the bunter-lever 14, which falls back against the stand 15 in the ordinary way. The movement of the bunter-lever 1'4, acting through a mechanism of ordinary construction and operation, (not shown,) throws reo oi the power; but the crank-shaft 2 does not stop immediately, but pushesby means of the crank-connector 3 upon the dwell-stand 5 in an upward direction, which causes the upper end of said dwell-stand to swing` or move on the pivot-pin 6 and the lower end 5 of said dwell-stand to move away from the lay-sword and compress the spring 20, thus relieving the sword and dwell-stand from the strain which might break the sword or dwellstand.

The advantages of my improvements will be readily appreciated by those skilled in the art.

It will be understood that I do not limit myself to the particular mechanism shown in the drawing for yieldingly connecting the lower end of the dwell-stand with the laysword, as other equivalent means may be used EUGENE RENZ.
