IMPROVEMENTIN LOOM-TEMPLES.

Speciiication forming part of Letters Patent N o. 124,004, dated February 27, 1872.

To all whom it may concern:

Be it known that we, WILLIAM MURKLAND and JOHN W. MURKLAND, both of Lowell, in the county of Middlesex and State of Massachnsetts, have invented certain new and useful Improvements in Burr-Temples for Looms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing making part of this specification, in which- Figure l represents a plan or top view, and Fig. 2 an inner-side elevation.

This invention relates to burr-temples, which have two arms or bars, one arm carrying the burr or roll, and the other arm carrying the cover or cap, and with a clear open passage between the roll and the cover, andalong open slot between the two arms, to allow suspended filling-threads, or those not in immediate use, when there are several shuttles, to pass down the side of the web and out of the way of the filling-forks and the filling-in action, to pre-V vent enlargement.

In the said drawing, A represents the slotted plate by which the temple is fastened to the breast-beam of the loom. Ears lL and f rise from opposite ends of the plate A, and these form supports forthe slidinglshank of the forked stem, provided with the usual spiral spring B, operating to press the stem or arms forward.`

The two arms a and d, which constitute the fork, extend forward from the shank I), as shown, and these are applied to the forward-ear h, and held in position with the shank by a glut, c', iitted between the two sides of the ear and fastened by a rivet, c. One arm, a, carries the roll or burr g at its forward extremity and in a horizontal position, while the other arm, d, carries the cover 7c of the roll, suitably arranged to press and hold the passing fabric in working contact with the toothed roll. Between the two arms c and d there is a long open slot, B5, and between the roll and the cover a clear open passage leading to the long open slot.

When this burr-temple is used on a loom which carries two or more shuttles, certain of the shuttles, with theirlling, are at times suspended or out of action, atwhich times these suspended iilling-threads, or any loose ends, pass readily between the roll and the cover and back into the long open slot, Where they remain until the shuttle or shuttles carrying such suspended lillin g are again brought into action. By this means each suspended filling-thread is immediately carried by the web out of the range of theiillingforks and of the iilling from the operating shuttle or shuttles; and this prevents entanglement ofthe filling by the beat of the lay, a-nd it a-lso prevents such suspended fillingthreads or loose ends being carried into the warp by the illing-in action, thereby producing more perfect goods, and preventing the necessity of stopping the loom to withdraw or pick out the loops or ends ot' entangled lilling, or that which should not have been inserted.

This peculiar burr-temple is of great importance in looms which carry several shuttles, whether these shuttles are changed by hand or by power, as it is necessary, or at least very important, that the lling-threads out of action should pass down unobstructed in direct connection with the selvage of the woven fabric, and ready to be brought into action without liability of entanglement.

We claim as our inventionl. The two-armed burr-temple, constructed as described, having a long open slot, B5, between the arms, said slot communicating by an unobstructed passage with the opening between the roll g and the cover k.

2. A divided or two-armed burr-temple, as described, one arm carrying the burr or roll g, and the other arm carrying the cover, and having a clear passage for suspended fillingthreads from the opening between the roll and cover to the opening between the arms.
