LOOM.

SPECIFICATION forming part of Letters Patent No. 251,801, dated January 3, 1882, Application filed April 4, 1881. (No modil.)

- To all whom it may concern;

Be it known that 1, CHARLES SMITH, of Belleville, in the county of Essex, State of New Jersey, have invented a new and useful .Improvement in Looms, of which the following is a specification.

My invention relates to improvements in looms, and is especially adapted to those for weaving wire-cloth, but may be used in any Wires while the filling is being driven up, as

herein set forth and claimed.

Figure l is an elevation of the back portion of the loom, mostly in section. Figs. 2 and 3 are detail sectional views, and Fig. 4 is a side elevation of portions of the loom, part being in section.

In my construction, A is the frame of a loom. B is the back beam or warp-roller, made loose on the shaft 0, and having heads provided with the flanged rims D of the heads, forming recesses, in which, fixed on the shaft 0, are received the spiders or arms E.

On the inside of therimsD arefixed notched lugs c, in each of which is placed a rubber or other spring, D, against which the arms E are made to bear.

On the end of shaft O is a spur-wheel, I connecting with a "pinion, G, mounted on the shaft H in the frame A. y

On the opposite end of the shaft H is a loose screw-wheel, I, having a flanged rim, 1', making a recess, in which, fixed on the shaft H, is received the spider or arms J, and this wheel and spider, with the interposed springs J, are arranged iuthe same manner and for the same purpose, as those before described connected withthe warpbeam. The screwwheel I engages with the screw or worm K,

which is made to slide on a feather, a, on the devices, enabling me to weave fine fabrics by reducing and regulating the tension on the warp.

O is a ratchet-wheel made fast to the shaft L, which is worked by arm P and pawl Q, connected to a treadle, R.

S is a roller on which the cloth, woven at a point directly above it, is wound.

The parts of-the loom forming directly no part of this invention are left out from the drawings.

T represents the warp as wound on the beam B and the cloth on roller S.

Now, it will be seen that when the lay is employed in striking up the filling the severe strain applied to the Warp-wire tends to stretch it; but the springs D at the ends of the beam B, lying against the end of arms E, which are fixed on the shaft 0, yield to the blow of the lay and lessen the strain on the warp, and consequently prevent the stretching of it.

In addition tothe above, the springs in screw-wheel I unite to accomplish the same result, adjusting finely the action of the lay but in some cases this last-named series of springs may be dispensed with.

The treadle and ratchet are the common devices for letting off the warp during the process of weaving.

These improvements may be applied to hand or power looms and for weaving all kinds of cloth, and other forms of working the springs in connection with the ends of the beam may be employed with the same result.

I claim- 1. The combination of the warp-beam B with the shaft 0, having the projecting arms E, and a. series of springs, D, bearing against projections on the beam and said arms E, and adapted to permit the beam to yield to lessen the strain on the warp when the lay is struck up, substantially as specified.

2. The warp-beam B, having the heads provided with the flanged rims D and stops or lugs o, in combination with the springs D, 4:. The shaft H, wheel Lspider J, andsprings [0 arms E, shaft 0, and means for operating the J, in combination with the worm K and means shaft, substantially as and for the purpose set for operating it, substantially as and for the forth. purpose specified.

3. The combination, with the shaft 0, beam B, spur-wheel F, shaft H, gear Gr, andthe spider J, of springs J, worm-wheel I, worm K, Witnesses:

shaft L, and means tor operating said shaft, HORACE HARRIS,

substantially as and for the purpose named. 1 N. O. BRISTOL.
