I NICHOLAS I. ALLEN, 0F EVERETT, MASSACHUSETTS, A SSIGNOR TO DRAPER COMPANY,

OF HOPEDALE, MASSACHUSETTS, A CORPORATION OF MAINE.

LOOlVI-TEMPLE.

Specification of Letters Patent.

Patented Nov. 23, 1909.

Application filed April 2, 1909. Serial No. 487,535.

To all whom it may concern:

Be it known that I, NICHOLAS I. ALLEN, a citizen of the United States, and resident of Everett, county of Middlesex, State of Massachusetts, have invented an Improvement in Loom-Temples, of which the folbeat-up, so that the temple takes a fresh hold on the cloth at each pick. In weaving certain kinds of fine goods it is not desirable to use temples provided with rolls having cloth-engaging pins, inasmuch as the pins tend to make slight holes adjacent the selvages.

In my present invention I provide holding jaws which engage and hold between them the cloth, and I have so arranged the temple mechanism that said jaws are opened sufliciently to release the cloth on the beat-up, so that as the cloth is taken up the jaws in closing take a fresh hold upon the cloth,- closure of the jaws being effected in a positive manner.

The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims, one practical embodiment of my invention being illustrated and described.

Figure 1 is a top plan view partly broken out, of a loom temple embodying one form of my invention, the cloth-engaging portions of the temple being in operative position; Fig. 2 is a side elevation of the temple shown in Fig. 1; Fig. 3 is a detail of a portion of the temple, in side elevation, and showing the cloth-engaging portions thereof as having released the cloth.

Referring to the drawings, the stand 1 adapted to be secured to the breast-beam of the loom in any suitable manner, has bearings 2, 3 for the temple shank 4: and its cylindrical extension 5, a coiled spring 6 coiled around said extension between the bearing 3 and the shoulder 7 of the shank normally acting to project the temple into the position shown in Figs. 1 and 2.

The shank 1 is reduced in thickness beyond the shoulder, for the greater part of its length, as shown clearly in Fig. 1, and at its extremity is provided with a laterally extended and rigidly connected pod or jaw member 8, having a depending heel 9 adapted to be struck by the lay on the beat-up.

A cap or movable jaw member 10 extends above the pod and has a rigidly attached arm 11 provided with a hub 12 to receive a fulcrum or pivot-stud 13 fixed in the shank 4, as shown, said arm lying against the adjacent upright face of the shank and having its forward or free end shaped to present a cam 141-, which normally projects slightly into the bearing 2, l

It'will be understood from the drawings that the opening in the bearing is the full width of the shouldered end of the temple shank, so that a clearance for the end of the cam 14 is provided within said bearing, adj acent the shoulder 7.

The upper convex face 15 of the cam cooperates with the cover-plate 2* of the bear ing, and the lower, concave face 16 of the cam cooperates with a transverse stud or pin 17 held fixedly in the bearing 2.

hen the temple is projected by the and the pin 17 maintains the jaw members 8 and 10 closed upon the cloth, but when the lay A, see dotted lines Fig. 8, beats up and engages the heel 9 the temple is moved forward, its shank sliding in the stand against the stress of spring 6, and the cam face 15 wipes under the cover-plate 2*. The effectthereof is illustrated in Fig. 3, the cam end 14 of the arm 11 being depressed to thereby raise the cap or jaw member 10, and as the two jaw members 8 and 10 are thus separated the hold upon the cloth is released so that the cloth can move forward freely as it is taken up. As the lay recedes the spring 6 operates to project the temple, as will be manifest, and at such time the edge or face 16 rides over the pin 17 and positively depresses the upper jaw member 10, closing the jaw mem bers upon the cloth, so that the latter is properly held.

Any suitable devices may be mounted on the jaw members to directly contact with the cloth, as for instance an annularly ribbed roll 20, Fig. 1, may be mounted in the member 10 and a correspondinglycorrugated seat 22 may be mounted in the member 8, to thereby effect a better and firmer hold upon the cloth and keep it stretched without injurin it.

Ihe particular character of these devices may be changed, however, and in themselves form no part of my present invention, it being understood that the opposed and relatively movable jaw members may be provided with any suitable form of contact devices.

Should the weaver desire to push the temple forward and retain it in that position while attending to other matters, he pushes the temple shank to the left, Figs. 1 and 2, until the transverse shoulder 48 on the shank can be made to catch against the front edge of the cover-plate 2*.

Changes in details of construction may be made by those skilled in the art without departing from the spirit and scope of my invention as set forth in the annexed claims.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a reciprocating loom temple, relativelymovable cloth engaging members adapted to be moved forward bodily by the lay on the beat-up, and positively acting de vices operating, respectively, to separate said members and release the cloth on the beatup and to thereafter positively act upon and close said members upon the cloth.

2. In a loom temple, a longitudinally mow able shank, a fixed aw member thereon and a cooperating jaw member pivotally mounted on the shank, to receive between them and hold the cloth, a cam connected with the pivotally mounted member, and having convex and. concave faces, and separate stationary means to cooperate with said cam faces and effect, respectively, separation of the jaw members on the forward stroke of the shank and positive closure of said members on the return stroke of the shank.

3. In a loom temple, a stand having bearings, a shank longitudinally movable in said bearings and provided with a rigidly connected cloth-engaging member having a heel to be engaged and moved forward by the lay, a spring to project the shank rearwardly a cloth-engaging member pivoted on the shank and having an attached arm provided with a cam, and devices on the stand one device being arranged to cooperate with the cam and rock said arm positively on each stroke of the shank, to open the cloth-engaging members on the forward stroke of the shank and the other device acting to close them positively on the return stroke.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

NICHOLAS I. ALLEN.
