IMPROVEMENT IN' TEMPLE POR LOOM.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, JOSEPH SIMPSON, of Millbury, Worcester county, Massachusetts, have invented a new and improved Loom-Temple; and I do hereby declare that thc following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to certain improvements in i cloth-holding devicesfor looms, and consists in certain details of construction, which will be more fully described hereinafter.

In the drawings- Figure l is a plan view of my invention, and

Figure 2, a side elevation of the same.

To enable others skilled in the art to 'make and use thesame, I will proceed to describe fully its construction and operation.

A represents the shank o' the lower jaw, to which is pivoted the upper shank B, both of which are bent at right angles at their outer ends, and are provided with diagonal teeth, which form the griping part of the Jaws.

rlhe upper shank is pivoted near its centre, and its rear end slants upward, so aS to admit of a sufiyicient depression thereof', to raise the forward end and open the jaws, which are kept closed by the spiral 'spring U, the ends of' which rest in recesses in the upper and lower shanks, near the rear ends ofthe same.

c represents aguide or strip, which is pivoted to the under side of' the shank B, and passesthrongh an elonggrated slot in the shank A, terminating in the transverse circular piece c.

On the under side of the shank A is a projection, D, having an orifice, through which passes a circular boit o r bumper, el, rigidly attached to ridge-shaped piece, d.

This latter is slotted vertically nearly its whole length, and through this slot passes the strip c, the

point of the wedge d being between the piece o and the shank A. v r

E represents a continuation ofthe shank A, which is hinged to the rear end of the same, and secured by means of the slot e and set-screw e', to the slotted plate F, and has a free longitudinal-sliding.motion thereon, the latter being attached to the breast-beam of the loom.

f represents a spring, one end of which is attached to the plate F, and the other presses against the end of the piece E. The device is operated by means ofthe lay beating up and striking the bolt d, and driving it with the wedge d backward, thereby drawing down the piece c', and with it the guide c, and opening the jaws sufficiently far to release the cloth.

When the lay recedes, the wedge follows it and the jaws close. p

When the harnesses open lthe shed, the hinged 'shank yields sufficientlyY to relieve the strain on warp and selvages.V

The spring f serves to keep the templein its proper position.

Having thus fully described my invention,

What I claim, and desire to secure by Letters vPatv I 1. The wedge-shaped piece d and bolt d, in combination vwith the guide c, piece e', spring O, and shank B, arranged and operated substantially as and for the purpose set forthf 2. Thev combination, with a temple, constructed as described, of the hinged shank E, with its slotted porL tion e, in .combination with the plate F and spring j,

las and for the purpose described.

This specification signed and witnessed, the 27 th day of February, 1869.

Witnesses: JOSEPH SIMPSON.
