LODM.

SPECIFICATION forming part of Letters Patent No. '77 5,895, dated November 22, 1904.

Application filed July 14, 1904. Serial No. 216,473. (No model.)

T 0 ztZZ whom it may concern.-

Be it known that I, J AMES H. COBB, a citizen of the United States, and a resident of Belton, county of Anderson, State of South Carolina, have invented an Improvement in Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates more particularly to broad looms, wherein the cloth is woven in a web of from sixty to ninety inches or more in width, such a loom manifestly being of several feet additional width from one to the other side.

The shipper of aloom is located at one side thereof and is released automatically upon the occurrence of various faults of warp or filling, and the shipper is set or moved into running position by the weaver when ready to start up the loom after a stoppage, the weaver grasping the handle of the shipper and moving it over into the usual notch of the holding-plate of well-known construction.

It is sometimes not only desirable but necessary for the weaver to start the loom while with one hand he manipulates or controls I some part of the warpas, for instance, when a warp-thread has been pieced up. This can be done on the loom of normal or average width, for the weaver can readily throw the shipper into running position with one hand and with the other hand attend to something at a point some distance away.

With a broad loom, however, the conditions are entirely different, as, owing to the width of the loom, it is absolutely impossible for the weaver to control much of the width of the cloth when setting the shipper. Not only this, but a trip of from eight to ten feet from one end of the loom to the other, repeated possibly many times in a day, adds much to the already arduous duties of the weaver.

My present invention has for its object the production of simple and effective means to set or move the shipper of a loom into running position from a point at a distance therefrom, whereby in a broad loom particularly many steps are saved, and the weaver can control portions of the loom or the cloth at a distance from the shipper.

' In the present embodiment of my inventionthe shipper-setting means is adapted to be actuated by the foot of the weaver, thereby leaving both hands free.

- The novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 represents in front elevation and centrally broken out a sufficient portion of a broad loom to be understood with one embodiment of my invention applied thereto,

and Fig. 2 is a plan view of the shipper-holding plate.

The loom sides 1, breast-beam 2, lay 3, having usual shuttle-boxes 1 thereon, the pickersticks 5 and their actuating mechanism, only a portion of which is shown, the shipper 6, fulcrumed at 7 at the left-hand side of the loom, its holding-plate 8, having the holdingnotch 9, Fig. 2, and the spring .9, helping to throw the shipper into stopping position when released, as shown in Fig. 1, and into the notch 9 when set, may be and are all of well-known construction in broad looms.

In the present embodiment of my invention .the front cross-girth 10 of the loom has fulcrumed upon it a manually-controlled actuating device to set the shipper and shown in Fig. l as a foot bar or plate 11, connected by pivoted links 12 with ears 13 on the cross-girth, so that the foot-bar can swing in a substantially horizontal condition from full to dotted line position, and vice versa.

The shipper is shown at the left-hand side of the loom, and the manually-controlled actuator 11 is located at or near the opposite side of the loom within the side frame thereof.

A long link or red 14: is pivotally connected at one end with the actuator at 15, and at its other end it is connected at 16 with a depend ing extension 17 of the shipper, the rod pass.- ing through an upright slotted guide 18 on the cross-girth.

A collar 19 is adjustably secured to the link 14, and between said collar and a washer 20, slidable against the guide 18, a spring 21 is coiled around the link, the spring normally acting to maintain the shipper and the actuator 11 in the full-line position shown and to move the shipper into such position when released from its holding-notch, either manually or automatically.

When the weaver wishes to start the loom and is not near the shipper, he places his foot upon the foot-bar 11 and bears down upon it, swinging it down into dotted-line position and moving the link 14 in the direction of the arrow 22 to throw the shipper 6 into running position.

As soon as the shipper arrives opposite the notch 9 in the holding-plate 8 the spring 8 acts in usual manner to direct the shipper into the notch.

It will be noticed by reference to Fig. 1 that when the shipper is in stopping position the swinging links or carriers 12 are somewhat off dead-center, so that the actuator can be readily depressed when desired to set the shipper, as

has been described.

The actuator can be made of sufficient length to enable the weaver to operate the same from any one of several different points, and not only will the weaver be saved many steps, but both of his hands are left free to attend to the warp, filling, or any portions of the loom mechanism.

The guide 18 prevents the link 14: from moving backward or forward in its longitudinal movement and also serves as the fixed abutment for the spring 21.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Ina loom, a shipper and its notched holding-plate, located at one side of the loom, a spring to move the shipper into stopping position when released, upturned swinging carriers located at or near the opposite side of the loom, a foot-bar supported by and pivotally connected with the carriers, to rise and fall by swinging movement of the same, and a link connecting the shipper and foot-bar, whereby descending movement of the latter will act through the link to positively move the shipper to running position.

2. In a loom, a shipper and its notched holding-plate located at one side of the loom, a foot-controlled actuator at the opposite side of the loom, rocking carriers pivotally connected with and supporting the actuator, and adapted to swing in an upright plane, a link pivotally connecting said actuator and the shipper, and a spring to move the shipper into stopping position when released and to rock the carriers and thereby move the actuator into elevated position.

3. In a loom, a shipper and its notched holding-plate located at one side of the loom, a spring to throw the shipper into the holdingnotch when set, an elongated foot-controlled depressible actuator located at a distance from and operatively connected with the shipper, rocking carriers pivotally connected with and supporting the actuator in substantially hori- Zontal position, and a spring to raise the actuator and move the shipper into stopping position when released, depression of the actuator by the foot of the attendant effecting the movement of the shipper into running position.

A. In a loom, a shipper and a device to retain it in running position, a spring to effect the engagement of the shipper with said device, a depressible foot-bar located at a distance from the shipper, upturned swinging carriers pivotally connected with and supporting the foot-bar, a positive connection between the latter and the shipper, and a spring cooperating with said connection to move the shipper into stopping position when released, and to swing the carriers and raise the footbar, depression of the latter acting through said connection to positively move the shipper to running position.

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