STOP MECHANISM FOR LOOMS.
Specification of Letters Patent.
v Patented June 2, 1908.
Application filed January 22, 1907. Serial N 0. 353,453.
To all whom itmay concern:
Be it known that I, ADAM A. WENDT, citizen of the United States, residing at South Euclid, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Stop Mechanisms for Looms, of which the following is a specification.
This invention is an automatic stop mech anism for power looms, and has for its object to provide improved means for stopping the machine when the shuttle fails to carry from one shuttle box to the other, or, in short, to avoid a smash when the shuttle is not properly boxed. The purpose of the swinging members is. to increase the motion imparted to the protector shaft.
The invention is illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the parts of the invention as applied to a loom, other parts of the loom being omitted as unnecessary to illustrate. Fig. 2 is a vertical sectional elevation. Fig. 3 is a plan view. Fig. 4 is a rear elevation of the batten. Fig. 5 is a lan or top view of the slay.
Re 'erring specifically to the drawings, the main parts of the machine are indicated as follows: A is the frame, B is the guide roll, C is the cloth beam or roll, D is a warp beam, and I is the batten. These parts are all driven or operated in a manner which is immaterial to the present invention and need not be described here, except to say that H is the main shaft of the loom. This shaft is driven by means of a friction clutch K the a the forwardly-projecting arm of which is held in position by means of a weight 25 suspended at the-rear end thereof. Directly behind the rear u right arm of the bent lever is a guide a ho ding a sliding bolt 0. to which is fixed a block 0. The bolt (1 is held in retracted position by means of a spring 11 coiled between a small fixed bracket 19 and a pin 20; and the front end of the bolt (1 is in proper position to strike the upright arm of the bent lever a when said bolt is advanced. On the batten I is a stationary Shaft i extending across between the lay standards or swords i, and su ported in hangers under the slay V. This sliaft has an arm or dagger i projecting downwardly and forwardly, and arms i which lap or project, at the upper end, over or behind swin' ing leaves or members 13 which are hinge to fixtures 2' fastened to the lay cap 1'.
Pivotally mounted to swing in a slot in the rear wall of each shuttle box is a binder or friction piece i and normally held in or forwardly by a spring 11 as it enters the shuttle box 71 and is there by forced out or back against the tension of the spring 2'.
The shifter pole a extends across. at the front of the machine, in convenient position to be manipulated, and it has at one end a shoulder a, which engages against the bent lever a heretofore referred to, thereby holding said shifter pole against movement. The said pole is connected to the shifter arm h which is rigidly fixed to the front end of the rock shaft h, and at the rear end said shaft has a yoke armh as heretofore referred to, for throwing the clutch K into or out of engagement'. A spring h connected between the shifter arm h and part of the frame, tends to pull the movable clutch member 7L5 away from the opposite member, to disengage the clutch.
As long as the bent or latch lever a, is engaged behind the shoulder. a the clutch remains in engagement and the machine is operated. When the shuttle carries well across from one box to the other it forces back the binder or pivot piece i causing said piece to strike the swinging plate 1' which in turn contacts against the arm i and rocks the shaft so that the dagger i is lifted, as indicated in dotted lines in Fig. 2, and on the forward swing of the batten, ,it will pass over and miss the block (L25. But when the shuttle fails to carry across the shed or to be This friction piece or binder receives the impact of the shuttle properlyboxed the pivot piece i will not be carried by the lay and having arms located behind and in the path of said plates and also having a dagger, a shifter to start or stop the machine, and latch devices controlling the shifter and actuated by the dagger.
2. In a stop mechanism for looms, in combination, a shuttle box, a pivoted binder located in the rear' wall of each shuttle box and arranged to be pushed back by the shuttle when it enters the box, a rock shaft extending across under the lay and having a projecting arm behind each shuttle box and also having a forwardly-extending dagger, a swinging plate carried by the lay and located behind each shuttle box and arranged to be struck by the binder when it is pushed back and to strike the arm and rock the shaft to lift the dagger, a sliding bolt mounted on the frame of the machine in front of the lay and having a projection extending into the ath of the dagger and arranged to be struck thereby when the dagger is depressed and to be missed when the dagger is ifted, a bent latch lever pivoted on the frame and having an upright arm at the rear end which is struck by the bolt when the latter is advanced, a shifter pole extending horizontally across the front of the machine and having a projection engaged by the latch lever, and means connected to the shifter pole to start and stop the main shaft of the machine, said means including a spring arranged to operate the same to stop the machine when the latch is released.
In testimony whereof I have affixed my signature, in presence of two witnesses.
