LOOIvI-STOPFING MECHANISM.
Application filed August 31, 1923. Serial No 660,451.
To all whom it may concern:
Be it known that I, ADoLrrI Srnrniuun, acitizcn of the United States, residing at Philadelphia, inthe county of Philadelphia and State of Pennsylvania, have invented a new and useful Loom-Stopping ldechanism, of which the following is a specification.
This invention relates particularly to carpet looms of the vArminster type in which yarn spools are supported on tube frames by which the yarn ends are presented between the warps of the fabric. In such looms it is desirable to provide means to stop the loom whenever a tube frame fails to be properly advanced to delivery position.
It is the object of my invention to render the operation of such a stop motion more reliable, and to prevent irregular disabling of the stop motion mechanism at times when its operation is required.
With this general object in view, my invention relates to certain arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.
A preferred form of the invention is shown in the drawings, in which Fig. 1 is a partial side elevation showing certain parts of a loom of the Axminster yp Fig. 2 is a front elevation of the parts shown in Fig. 1;
Fig. 3 is a partial front elevation of a tube frame and end support or bracket embodying my improvements;
Fig. 4 1s a partial front elevation simllar to Fig. 3 but partly in section and showing the parts in a different position;
Fig. 5 is a detail sectional plan View taken along the line 55 in Fig. 3, and
Fig. 6 is a perspective view of a chain attaching hook.
Referring particularly to Figs. 1 and 2, I have shown parts of an Axminster carpet loom including a loom side 10, one of a pair of positioning arms 11 by which a tube frame is detached from the transporting chain and is presented to the warps, a shipper lever 12 and loom stopping mechanism effective to release the shipper lever and controlled by one of the positioning arms 11.
The stopping mechanism comprises a bell crank 13 mounted upon a fixed pivot 14 and engaged by a cam plate or striker 15 at each revolution of the cam shaft 16. A rod 1'? is pivoted at 18 to the upper end of the bell crank 13 and is provided with a hook tioned to engage one arm 25 of a two-armed lever 26 which is pivoted upon a vertical stud 27 supportedby a bracket 28. The second arm 29 of the two-armed lever 26 engages a projection 30 on the side of the shipper lever 12' and when actuated by the stop motion moves the shipper lever to throw ofi the power and stop the loom.
A vertical rod 31 is pivoted at 32 to the opposite end of the rod 17 and extends upward through a bearing 33 into position for engagement by a. portion of the positioning lever 11 as it moves downward by gravity to present the tube frame to the warp. When the rod 31 is thus engaged and pressed downward, it raises the hook 19 above the ledge 20, thus disabling the stop motion and preventing the operation thereof to stop the loom.
If each tube frame is not successively de tached from the transporting chains. it is required that the stop motion operate immediately to stop the loom. It has been found, however. that the positioning arms 11 sometimes slip off of a tube frame which is held in raised position and continue their downward gravity movement, thus disabling the stop motion at a time when its operation is desired.
An important object of my invention is to provide means for preventing such irregular disabling of the stop motion mechanism. In Figs. 3, 4 and 5 I have shown a tube frame and supporting bracket which are of the-general type shown in the prior patent to Ryon, No. 1,458,312 issued June 12. 1923.
These parts comprise a rectangular tubular member 40 4) having a spool bearing 41 and a chain engaging member or guide 42 rigidly secured in the end thereof. An attaching hook extends through slot in the part 42 and is provider l with n the tube tranie w nch acts to press the hook outward to enn'ae'e the transportng chain. r-J: a the oivotal point provide a his;
For purpose and nushiwr thorn shown in Figs. 1-1
noa 'in the to the position erebv s ng i been .me should no; chains the tran o2 The operation of the stopnina mechanism is thus rendered more certain and etiective and irregular disabling; thereof is prevented.
Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what I claim is in a looni having a plurality of yarn tibe frames rzeans to present said tube 2' s *ely in yarn delivery position, means to stop the looin when by gravity to move said deposition and means to presuch mo nt of said supporting arm the tube traine supported hereby rere sed position.
echanisin e set forth in claim sail laa'ter means includes an win on each tube frame, in said supporting; arm has a releasing device movable to engage said spring arm and to disconnect the same and in which said latter 08118 also includes a projection in line with and normally below said eicasinn devie, and positioned for engagement thereby it said su iporting arln slips downward relative to said tube :l'raiiie.
A room mechanism as set forth in claim in which said latter means includes an atachinp; spring arm pivoted on each tube frame. in which said supporting arm has a releasing device movable to engage said spring" arm and to disconnect the same, and in which each spring arm has a projection adjacent its pivot normally below said releasing; device an d positioned for engagement thereby it said supporting arin slips downward relative to said tube frame.
In testimony whereof I have hereunto d ni signature,
ADOLPH STRIEMER.
