LOOM-TEMPLE.

SPECIFICATION forming part of Letters Patent No. 415,172, dated November 12, 1889.

Application filed July 13, 1887.

To all whmn it ntay concern.-

Be it known that I, CHARLES A. LITTLE- FIELD, a citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Loom-Temples; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has for its object to provide means whereby the temple-bar or the bar carrying the temple-roll may be adjusted not only horizontally, longitudinally, and vertically, but may also be turned about a line drawn centrally through the said bar from end to end in order that when the said bar becomes worn by use it may be moved or turned on or with relation to the stand which connects it to the breast-beam in such manner as to maintain the axis of the temple-roll substantially parallel to the raceway of the lay.

In this my invention the inner side of the breast-beam in practice has attached to it, near each side of the loom, a slotted plate having a concaved surface with which co-operates the conveXed face of the arm or shank of a stand made adjustable on the said plate. The stand referred to contains an adjustable guide made as a sleeve, which receives within it the temple-bar, which at its outer end carries the usual temple-roll, cover, and trough. The temple-bar within the guide referred to is surrounded by a spring, and the guide and 'bar are connected by a slot-and-pin connection, whereby the bar is free to slide longitudinally to a limited extent within the guide, but cannot move therein in any other direction independently of the guide; but the guide may be adjusted within the stand in such manner as to maintain the stud or axis upon which the temple-roll turns parallel, or substantially, so to the raceway of the loom to which the temple is to be attached.

Figurel is a top or plan view of a sufficient part of the breastbeam of a loom, near one end thereof, to show my improved temple mechanism attached thereto. Fig. 2 is an Serial No. 244,138. (No model.)

elevation of Fig. 1 looking at it in the (ll16C- tion of the arrow thereon. Fig. 3 is a righthand end elevation of Fig. 1, the said figure showing, however, the end of the breast-beam, which is supposed to be of metal; and Fig. 4 is a section of Fig. l in the dotted line Similar letters of reference refer to like parts on the drawings.

The breast-beam A, which is and may be of any usual construction, has secured to it at its inner side a supporting-plate O for each temple to be used, the said supporting-plate having its side or face toward the lay (not shown) concaved, as at c, the said plate being slotted longitudinally, as at c, and being attached to the breast-beam by suitable bolts r r, the said bolts entering slots 0 in the said plate to enable it and the parts attached to it to be adjusted vertically on the breastbeam. At its inner side the plate 0, along the edge of the slot 0', has two lips 0 which bear against the breast-beam and complete a channel for the head g of the screw g.

The stand F is composed, essentially, of a hub having a downwardly-projecting arm or shank f, the side of which next the plate 0 is convexed, as shown at Figs. 3 and 4, to fit the concaved face of the said plate, the said arm or shank being slotted at f to receive through it the adj listing-screw g, the stern of which is free to slide in the slot 0' of the plate 0, and the head of the said screw being free to move between the said plate and the inner side of the breast-beam, the said screw having applied to it a suitable nut 9*, which when turned upon the screw holds the stand or arm in adjusted position, the said stand being adjustable horizontally to acommodate the temple to the width of the cloth being woven, and also vertically, the vertical adjustment being in the are of a circle, whereby the rear part of the temple may be raised or lowered for a considerable distance to meet the varying conditions in relative height of the breast-beam and lay without materially changing the position of the temple-roll itself.

The temple-roll d, of usual construction, has as its axis or center of motion a stud or shaft 61*, supported in usual manner within a cap or cover (1 and a trough d", forming part of the said temple, an extension of the trough having secured to it in usual manner a heel-piece Z, which is struck by the lay to move the temple back with it.

The stud 61* and temple-roll d are carried by the temple-bar D, which, reduced in diameter for part of its length, is inserted in a cylindrical guide N, made as a sleeve fitted into the hub of the stand 1*, the guide being held in adjusted position in the said stand by means of suitable adjusting-screws f whereby when the screws are loosened the guide or sleeve may be turned or partially rotated within the stand to enable the axis of the roll cl to be brought into position parallel, or substantially so, with the level of the raceway of the lay, and the guide to be adjusted horizontally in the stand F.

The bar D, within the guide or sleeve N, is surrounded by a spiral or other suitable spring e, and is also slotted, as at d, to receive a pin or projection 12, the said slot and pin permitting the bar D to slide longitudinally for a limited distance within the guide N, but preventing it from turning around in the said guide.

Prior to my invention the carrier-bars inloom-temples have usuallybeen made square to enter a square or loop-like piece of metal forming part of a stand by which to operatively connect the temple to the loom; but in practice the said sliding carrier-bars soon become worn at their corners, and, not being held securely, they twist or turn in such direction as to throw the axis of the templeroll so far out of parallelism with relation to the level of the raceway of the loom as to cause the temple to injuriously strain the cloth and produce bad work. By interposing a cylindrical guide or sleeve between the bar and stand I am enabled to adjust the position of the guide or sleeve by slightly'rotating it, and thus compensate for all wear of the temple-bar due to its frequent reciprocations, this adjustment being one of the chief features of this my invention.

Prior to my invention I am not aware that such adjustment has ever been provided for in a temple, and therefore I do not desire to limit my invention to the exact construction of the guide or sleeve or to the precise devices shown by which the said guide or sleeve may be adjusted in the stand. By entirely inclosing the spring 6 within the guide or sleeve N all danger of soiling the fabric by oil applied to the temple-bar is obviated.

I claim- 1. The stand having a cylindrical opening, means to support the stand, the cylindrical guide supported in said stand, the templebar adapted to slide in the said guide, and the operating-spring e, combined with means to hold the said guide in adjusted position 011 the said stand, substantially as described.

2. The temple-bar, the temple-roll carried by it, the spring, and the guide or sleeve to receive the temple-bar, combined with the stand and with means to permit the guide or sleeve to be turned in the said stand to compensate for wear of the temple-bar, substantially as described.

3. The slotted temple-bar, the temple-roll carried thereby, the spring, and the guide or sleeve made circular externally, and a pin or projection 12., combined with the stand, means to hold it, and with means to hold the said guide in the said stand, substantially as described.

4E. The temple-bar, the temple-roller, the spring, the guide or sleeve, and the stand having the arm or shank convexed at one side, combined with the 'plate- 0, concaved at one side, and with a belt or screw to connect the said arm and plate adjustably, substantially as described.

5. The plate 0, slotted longitudinally, as at c, the stand having the slotted armor shank, means to connect the arm and plate, the guide or sleeve cylindrical externally, and means to connect the stand and guide or sleeve, combined with the temple-bar, a roll d, the baractuating spring (2-, and with a pin or projection to limit the extent of the longitudinal movement of the temple-bar, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES A. LITTLE FIELD.
