STOPPING DEVICE FOR LOOMS.

Specification of Letters Patent.

Application filed July 23, 1908.

Serial No. 444,901.

To all whom it may concern:

Be it known that I, DESIDERIUS SoHATz, director, a subject of the King of Hungary, and resident of Zittau, Kingdom of Saxony, German Empire, have invented a new and useful Improvement in Stopping Devices for Looms, of which the following is a specification.

The present invention has for its object an improvement in stopping devices for looms on slipping thread and consists of the arrangement of a falling-lever pivoted to the lever for disconnecting the loom.

A stopping device arranged according to the present invention is shown in Figure 1 in longitudinal elevation and in Fig. 2 in plan, whereas Fig. 3 shows a detail of some parts of this stopping device in an intermediate position.

a is the falling-lever pivoted at a on the shipper-lever 6 which during the operation of the loom engages a rest not shown in the drawing. The forward end of the lever a tapering on one side rests on the lower hook-shaped projection c of a lever c which is pivotally suspended at c on a plate d fastened at any suitable position to the frame of the loom or its breast-beam. The lever 0 can be moved by a treadle (not shown) or in any other convenient manner, such treadle being connected with a cord 0 running over a roller (2 fastened to the plate d. On pulling down the cord 0 by actuating the treadle, the lever c is moved from its position shown in Fig. 1 in full lines into the position shown in dotted lines. By the swinging movement of the lever c the forward end of the lever a is disengaged from the projection 0 and the lever on will swing in a downward direction around its pivot a and its notch f of angular shape will meet with a bent wire support 6 pro truding from the plate 03. Thus the downward movement of the lever a is limited by the bent wire support 6, as clearly shown in Fig. 1. In this position the front end of the lever a will be situated in the path of a rod or element 9 of flat or circular section and protruding sidewise of the lathe not shown in the drawings, and on the beating of such lathe the lever a and thereby also the ship per-lever b are actuated in such a way that this lever b will be displaced from its rest (not shown) and moved into its rear-position causing the stopping of the loom. Such position of the parts mentioned is shown in Fig. 1 in dotted lines. During the movement of the shipper lever 6 into the position of disengaging the loom the lever a will by its wedge-shaped notch f be simultaneously raised by the bent wire support 6 into a position suitable for the rengagement of the loom.

The lever a is of such a length that its pointed end will still rest on the bent wire support 6, when the shipper-lever b is in its disengaged position. By this means the bent wire support 6 holds the front end of the lever a, while the loom is again in operation, in such a position that its point has already passed the hook-shaped end 0 of the lever c which in the mean time is returned to its position of rest, before the notch f of the lever a comes in contact with the bent wire support 6, so that the bent wire support 6 raises and holds the falling lever a in a raised position during the lateral movement of the shipper-lever.

By so arranging the support 6 and the notch f of the lever a as described it is possible to make the stopping device ready for work again, without necessitating a new or special handling or operating movement.

As the slightest pull of the lever 0-will be sufficient to move the falling-lever a away from its operative and horizontal position, the device described is very delicate and may be used for various purposes.

It will be readily understood that the swinging movement of the lever a may be effected by any suitable means, and therefore I do not wish to limit myself to the employment of the roller (Z1 .and cord 0 for such purpose.

I claim as my invention 1. In a stopping device for looms, the combination with a shipper lever, of a falling-lever pivoted thereon, the said fallinglever being provided with a notch in one edge thereof, a bent wire support for engaging and supporting the falling-lever during the lateral movement of the said shipperlever, and a swinging lever for supporting the end of the said falling-lever, the said parts being so arranged that the reengagement between the end of the falling-lever and the swinging lever takes place before the bent wire support has returned beneath the notch of the falling-lever.

movement of the saidshipper-lever, in which movement the said falling-lever is moved by the said shipper-lever with the lower edge of the former resting upon the said bent wire support, a swinging lever and a projection on the said swinging lever for its normal position.

3. In a stopping device for looms, the my invention I have signed my name in combination with a shipper-lever, of a falling-lever pivoted thereon, the said fallinglever being provided with a notch in its,

lower edge, a plate fixed on the loom frame,

a bent wire support fastened sidewise to the said plate and adapted to engage and support said falling-lever during the lateral movement of the said shipper-lever, in which movement the said falling-lever is moved by the said shipper-lever with the lower edge of the former resting upon the said bent wire support, a swinging lever, a projection on the said swinging lever for supporting the end of the falling-lever in its normal position and means for actuating the said swinging lever to remove the said projection thereof from beneath the end of supporting'the end of the falling-lever in,

the said falling-lever.

In testimony that I claim the foregoing as presence of two witnesses, this eleventh day of July, 1908.
