FILLING STOP MoTIoN ron LOOMS.
Application filed November 2, 1925. Serial No. 66,132.
This inventionrelates to filling stop motions for looms and it is the general object of the invention "to providefsuch tIIIOlZlOIl located approximately at the center of the loom and connected'by a minimum number ofparts tothe shipp ng mechanism of the floom." p When center stop motions haveheretofore been applied to the Knowles type of loom to which'my "invention more particularly relates it has been customary to'provide an upright rod normally lockedin down position but, releasedby the stop motion to move upwardly underactionof-a spring to effect ll i'stopping of the loom. The releasing of this rod is etfectedby giving it a slight lateral movement by mechanism controlled by the fillingffork motion and itis a more particular object of, my invention to simplify and strengthen this intermediate mechanism to the end that the same may be more dependable and require less attention.
It is'a further objectof my invention to alter one of thepartsfofthe commonly used stop motion so that the control lever will be moved by dire'ctengagement with the actuated lever to move in a plane parallel to the force which must be exerted to, release the aforesaid upright rod. I
It is a stillfurther object of invention v toprovide a motion so constructedthat: by
I a very slight adjustment the same parts may either a right ora left hand be employed for 1 loom.
V With these and other objects View "which will appear as the description. proceeds my invention resides in the combiner.
'tionand arrangement of parts hereinafter described and set forth inIthe claimsp In the accompanying drawings wherein I Q have shown a convenient embodiment of my invention,
Fig. 1 is a vertical section taken through a portion. of a loom and showing my improved stop motion applied thereto, 1 Fig. 2 isja vertical section on line 2 2 of 1 showing the parts in normal running 7 Position, Fig.3 is aview similar to Fig.2 showing the parts in knocking off positlon. I
Fig. 4is a top plan view looking inthe I direction of arrow 4, Fig. 2,.showing the knocking otl mechanism, and. p,
Fig. 5' is a fragmentary side elevation looking in the direction of arrow 5, Fig. 4, parts being broken away for the sake of clearness.
- Referring to the drawings it will-be seen I that I have provided a breast beam 10 to the rear face of which is secured a bracket tially horizontal run 17 and an inclined cam face 18. A stud 19 secured in finger- 14 has pivotally mounted thereon an actuating lever 20 the upper end of which extends above the top of the arm 13 and is positioned as to its rearward' movement by a laterally pro-- jecting lug 21 integral with said arm 13.
The lay 22 has secured to the under side thereof a stand 23 on which is pivotally mounted a dagger support 24 from the forward end of which extends a dagger 25. The lower end of a rod 26 is pivotally connected .to the dagger support 2 1 and the upper end thereof is connected to an arm 27 rigid with a tine frame 28 which supports tines 29 forming the detecting element of the stop motion. The lay is provided with a transverse slot 30 which is positioned to receive the tines when weft is. absent.
Aslthe lay advances the dagger 25 moves first along the run 17 and then down the incline'18. This descent of the dagger is accomplished by a lowering of the tines and ifwill' be held against moving intothe'slot 30, thus holding the'dagger 25 above the rear end of actuating lever 20 and as the lay continues to move forwardly said dagger will leave lever 20 unmoved. ,Should the shuttle Sfail to lay'filling, however, the dagger 25 will move all the. way'down incline 18 and as the lay'continues to advance said dagger will engage the lever 20 and swing the same about stud'19. The lever 20 is limited in its downward motion by a stop 31 'wefthas been laid by the shuttle S the tines Y cast'integral' with fingerl i. Thisportion of theflmechanism is substantially. the same as that shown in patent to Hutohins, No. 560,036, granted May-12, 18 96. v
may be made therein by those skilled in the art without departing from the spirit and scope of the invention, and I do not wish to be limited to the details herein disclosed but what I claim is:
1. In a filling stop motion for a loom having a bar normally locked when the loom is ing a fixed bracket. and a bar normally locked when the loom is running, an actuating lever pivoted to the bracket, a cam carried by the actuating lever. and having a face extendmg obliquely with respect to the plane in which the actuating lever moves, a control leverpivoted to the bracket and movable by direct contact with the cam when the latter moves, and connections between said control lever and the normally locked bar to move the latter to unlocking position when the actuating lever is moved. 7
3. In a filling stop motion for a loom having a fixed bracket and a bar normally locked when the loom is running, an actuating lever pivoted to the bracket and having a cam face extending obliquely with respect to the plane in which said actuating lever moves, a control leverpivoted to the bracket and having direct operative connection with one end of the cam face when the actuating lever is in normal position, and connections between the control lever and the normally locked bar to move the latter to unlocking position when said actuating lever moves to cause relative motion of the cam face and control lever. I
4. In a filling stop motion for a loom having a bar. normally'locked when the loom is running, an actuating lever movable about a fixed pivot, a cam face on said actuating lever extending obliquely with respect to the plane in which the said lever moves, a control lever movable about a fixed pivot I and having direct engagement with the cam face, connections extending between the control lever and the normally locked bar to move the latter to unlocking position when the'actuating lever is moved to cause oscillation of the control lever by means of the cam face, and yielding means acting through the connections to hold said control lever against the cam face to hold said actuating lever in normal position.
5. In a filling stop motion for looms, an actuating lever movable about a fixed center, a pair of oppositely disposed cam'faces on said lever lying on opposite sides of a plane passing between them and parallel to the plane in which the actuating lever moves, a control lever, and a support for said control lever to mount the same in either of said lever, a control lever and a support for said control lever to mount the same in either of two positions, said control lever having operative engagement with one cam face in one position and having operative engagement with the other camface in the other postopping movement when in either position when the actuating lever is moved.
7. An actuating lever for a loom filling sition, said control lever receiving a loom stop motion having a control lever to be oscillated and a bracket for supporting said actuating lever in two positions, said actuat-ing lever having a pair of oppositely disposed cam faces extending obliquely with respect to the plane in which the actuating lever moves when in position, either of said faces being effective to cooperate with the control lever to, give thesame a loom stopping motion.
In testimony whereof I have hereunto aflixed my signature. r
