I Gustave AaGeeraerLLawrencaMass- '7 H Application. Ju y is, 1943;, sen ing. 494,98?) 2 Claims. I (01. Isa-37m- I This invention relates'to a filling stop motion compeller for looms and. has for an ob-ject to provide, a circuit. closer for the warp stop: solenoid adapted to be struckby the dagger of they lay high, tostop' the loom.

when the travel of-I the dagger is abriornria .lly

A further objectis to provide a device o f this character which is. adaptable: to looms using electric' warp stop motion, and is intended to utilize the warp stop motion knock-off when the filling stop motion fails.

Bending of fork wires caused by a shuttle leaving the shuttle box in a wobbly manner, or by a weaver throwing the shuttle through by hand,

will prevent the dagger operating. the filling stop motion shipper rod for stopping the loom. The same conditions occurs when the well in the lay, and other parts, become clogged with waste. Also loose securing screws of the fork wires extending out and striking back of the race plate,

or striking the bottom of the reed, will render the filling stop motion inoperative, since because then the dagger will travel abnormally high and cannot operate the shipper rod.

With the above in mind a compeller is located in front of the center of the breast beam according to the present invention, and is wired to the sive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of confFig ure v3 is avertical sectionalvi ew o fl compeller taken on the line, 3-3 ofFigureQ Figure 4 is a bottomplan view of the; com

. peller shown in 2.,-

Referring now to the drawing in which like characters of reference designate similar parts in. the, various. views, 6 designates the breast beam of a 100m, and l-Qthe reciprocating lay which 2; swings back and forth toward and away fr'om'tlia breast beam, Secured to the breast beam, midway of said beam is a filling stop motionstand 8 having an arm 9 adjustably fastened to the arm by a bolt l0, and havinga cam H. A tumbler I2 is pivotally mounted on a pivot stud l3 carried by the arm and is normally held by a spring, not

shown,- in the position shown inFigure 1, in'

which position a lug I4 on thetumbler abuts the upper face of the free end of a shipper rod l5 which shuts off the power when the tumberis engaged and actuated by the dagger in the event of failure or breaking of a thread.

The dagger I6 is secured to a dagger socket H which is pivoted on a bracket l8 carried by the lay l. The dagger directed at the free end to project over the arm 9 andover the cam H. A spring, not shown, acts to hold the dagger upon the camand serves to cause the dagger to follow the curve of the arm as the lay oscillates, the normal travel of the dagger being such that a broken thread operation would cause the dagger to drop and strike the tumbler 12, following a line of travel indicated by the dot and dash lines and the legendYNormal in Figure 1.

Fork wires i9 are secured to the lay 1 and project above a well 20 formed inthe upper surface of the lay; The fork wires are connected to a shaft 28 which is connected'by an arm 22 to the dagger socket I1. All the above are conventional loom parts.

struction and'combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming apart of this specification:

Figure l is a side elevation of a portion of a loom, a compeller constructed in'accordance with the invention being shown attached to the filling stop motion stand of the breast beam. 7

Figure 2 is a front elevation of the compeller.

Should the fork wires become bent, for reasons heretofore mentioned, such as waste accumulating in the well, or by the wires striking the reed 4, or by reason of loose attaching screws permitting the fork wires to strike the reed 4 or race plate 23 which causes the shuttle (not shown),

the dagger 16 no longer can travel thepath indicated by the normal dot and. dash line marked with the legend Normal in case of a broken thread operation but instead will be deflected upwardly and held to travel a path materially above the, normal path and indicated by the dot and dash'line and the legend Abnormal in Figure 1.; While traveling the abnormal path it n v is impossible for the dagger to strike the tumbler t Y the breast beam 6.

U form is secured to the plate 25 by bolts'30'. A

of substantially rectangular contour formed of insulating material and provided with a longir,

'tudinal slot 26 and an opening 21 in one side communicating with the slot to permit the plate being 1 attached to the filling stop motion stand by one of the'securing bolts 28 which attach the. stand to conductor 3| is secured to one of the bolts and is connected to the warp stop solenoid, not shown.

What is claimed is: V

1. A circuit closer for looms of the type having both a filling stop motion, and an electric warp stop motion, and wherein the filling stop motion is located in the path of travel of the dagger when a thread fails or is broken, a circuit closing device connected with the solenoid of the warp stop motion and fixed to the breast beam of the loom above the filling stop motionpa'nd adapted to be engaged by the da er when the dagger by reason of abnormal conditions fails to move in a path which would actuate the filling stop motion.

,2. A circuit closer for looms of the type having both afilling stop motion and an electric warp stop motion, andwherein the filling stop motion is located in the path of travel of the dagger when 1 a thread failsor is broken, a circuit closing device A brass spring 29 of inverted,

When the daggertravels the abnormal path indicated in Figure 1 it contacts with the brass spring 29 and closes the warp stop solenoid circuit at this point to energize the solenoid and stop the loom.

From the above description it is thought that k the constructionand operation of'the invention will be fully understood Without further explanation. v V

h connected with the solenoid of the warp stop v motion and fixed to the breast beam of the loom above the filling stop motion and having an insulating base plate with a longitudinal slot v communicating'with a side opening, and an inverted U-shaped contact spring on the plate adapted to be engaged by the dagger when the dagger by reason of abnormal conditions fails to a move in a path which would actuate the filling stop motion.
