LOQM-TEMPLE.

SPECIFICATION forming part of Letters Patent No. 284,120, dated August 28, 1883,

v Application filed August 15, 1882. Renewed June 27. 1883. (No model.)

To aZZ whom it may concern.-

Be it known that we, GEORGE GRoMPToN and HORACE WYMAN, of Worcester, county of Worcester, State of Massachusetts, have invented an Improvement in Loom-Temples, of which the following description, in connection with the accompanying drawings, is a specification.

Our invention has for its object the production of a-teniple to engage and keep the selvage of woolen or worsted goods properly distended in a fancy loom.

Our invention is composed of a hook to engage the fabric at the selva'ge thereof, a'strap connected with said hook, a spiral spring with which the strap is connected, a stud to hold the opposite end of the spring, a plate or arm to hold the stud, and a drum to surround the spring and stud and receive upon it the strap as the drum is turned by the spring.

Figure 1 represents in top View a portion of a loom and a web of fabric therein with our temples added; Fig. 2, a partial vertical section taken through the drum, spring, stud, and plate; Fig. 3, a detail looking at one side of the drum; Fig. 4, a section of Fig. 3 on the dotted line mm; Fig. 5, a section of Fig. 3 on the line a Fig. 6, a top View of Fig. 3, and Fig. 7 a sectional detail of the hook and strap.

The loom-frame A and breast-beam B may be as usual. Extended from the frame are arms or plates a. Upon each arm, by a screw,

a, is secured a stud, b, notched at its lower end to receive and hold the bent end of the spring 0, as in Figs. 2 and 4.. The opposite end of spring 0, provided with a hook, 0 is extended outward through a slot, 2, in the drum d, (see Figs. 3 and 5,) where it has hooked upon it one end of the strap 0, the latter having at its other end the hook f, provided with several sharp or pin-pointed prongs, f to enter the fabric 9 near its selvage edge, as shown in Fig. 1. The drum (1 has a hub, 61*, which. surrounds a reduced circular portion, N, of the stud b, and turns thereon easily. The spring 0 is so wound and held that it always acts by its upper free end to turn the drum (1 about the stud as the spring unwinds, and during such movement the strap 6 is wound about the loose drum (1, as shown in the drawings. The power of the spring and the extent of its movement to turn the drum and wind the strap may be regulated by loosening the stud b, turning it, and again fastening it in position by the screw a. The drum is kept from leaving the stud by the pin 1).

We claim- A temple composed of the arm or plate a, stud b thereon, a spring surrounding the said stud, a drum, (1, slotted at one side and placed loosely upon the said stud, a strap connected with the said spring, and a hook attached to the outer end of the said strap, substantially as shown and described.

In testimony whereof we have signed our names to this specification. in the presence of two subscribing witnesses.
