THREAD CUTTING TEMPLE FOR LOOMS.

Application filed August 21, 1915.

To all whom it may concern Be it known that I, lVILLIAii R. \V moor, a citizen of the United States, and resident of Spartanburg, county of S artanburg, State of South Carolina, have invented an Improvement in Thread-Cutting Temples for Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to thread cutting temples for looms and the principal objects thereof are to provide means to more certainly sever the thread upon the first for- Ward'movement of the lay after transfer and also to sever the thread more closely to the selvage or edge of the web of cloth. The loom temple forming part of the present invention is of the-type forming the subject matter of Patent No. 585,465 granted. June 29, 1897 in which the temple-head is provided with means to out the filling end extending from the automatic nism after the latter has been operated to supply the shuttle with fresh filling. The temple-head disclosed in the patent aforesaid is slotted transversely at its outer end to receive cooperating fixed and movable blades which are arranged to engage and cut the filling end. These blades comprise a single stationary blade fixed to the templehead and an oscillating and sliding movable cutter, the end of which is hook shaped and is bifurcated to receive and to cotiperate with both sides of the stationary blade. Looms employing this'type of thread cutter are usually provided with filling parting and holding devices which sever the end of the filling leading to the carrier upon replenishment at the same time grasping the filling and, carrying the end laterally so that it is brought into the field of action of the tempie thread cutter where it is again severed in proximity to the selvagc. In the prior blade lies intermediate of the blades of the movable cutter. in my improved device another stationary blade is located closely adjacent to the end of the temple roller so that one side of the blade acts as a guide for the selvage while the edge of the othe of said blade forms a cutter, thus h read is severed closely to the me making a neater cut of cloth and also p venting the-possibility of Specification of Letters Patent.

the severed end being whipped into the fell of the cloth by the suction of the shuttle as it passes across the loom.

In temple thread cutters of the usual construction above described the wear of the parts due to the constant vibration of the lay in time renders the coiiperation of the blades ineffective so that the cutter will not operate properly upon the first beating up of the lay after transfer, the cutters instead of severing the end merely grasping the same so that the subsequent movement of the temple serves to place thread which will cause it to break between the temple thread cutter and the holding device thereby leaving a loose end which is whipped into the loom, thus damaging the appearance of the goods. By providing a plurality of stationary cutters, adapted to cooperate with a corresponding number of movable cutting blades the severance of the end of the filling is assured, first, because the cutters are steadied in their movement by increased lateral bearing surfaces and second by reason of the fact that a larger number of cutting blades engage the thread.

The nature and objects of the invention will more fully appear from the following description and the accompanying drawings and will be pointed out in the annexed claims.

The drawings illustrate a temple thread cutter of shown in Patent No.

which my improvement has been embodied.

be of the usual constructlon comprising a head 1 having a rearwardly extending arm or slide bar 2 adapted to be supported in the usual stand upon the breast beam of the loom. The temple head comprises the pod 3 and cap 4 which are secured together by a screw 6 provided with a locking nut 7 in the usual manner a toothed roll 8 being mounted upon a shaft 9 journaled in brackets in the ends of the cap.

Adjacent the outer end of the roller the pod is preferably provided with a vertical slot 10 in which is seated a plurality or group of stationary cutting blades 11 which desirably are separated by a plate or shim 12 corresponding in thickness to the thickness of the movable cutter blade, one of these blades being located adjacent to the edge of the toothed roller 8 and forming a guide for the selvage of the cloth. The blades and shim may conveniently be clamped in position by a screw 13 in the usual manner.

\Vhile I have illustrated in the drawing two stationary blades cooperating with corresponding movable cutting blades it will be understood that a greater number of stationary blades and a correspondingly greater number of movable blades may be utilized within the spirit and scope of my invention.

The movable cutter it may be of the general form illustrated in Patent No. 585.465 aforesaid which comprises a body portion l-t slidably mounted in a slot 15 in the cap, the rear end of the blade 15 resting upon a portion of the base of the pod upon which it is adapted to have rocking and sliding movement. The forward end of the cutter may be bifurcated but preferably is provided with a plurality of attached steel blades 16. These blades are hook shaped as in the construction disclosed in the patent above 1'0 ferredto. The rear end of the cutter is provided with a downwardly extending heel 17 having a laterally extending stud l8, and a spring 19 connected to the stud 18 and a stud 2O upon'thc slide bar 2 serves to maintain the cutter normally in extended position. The temple is provided with the usual heel 21 adapted to be engaged by the lay as it heats up the fillin In operation the cutter stands normally with its hooked end or cutters 16 in elevated position andremoved a distance from the front of the blades ll. As the lay comes forward at each beat, after the filling has been thrown into the shed, the lay firs-t strikes the heel 17 of the cutter, causing the hooked end to move first downwardly so as to engage any filling which may have been trought into the field of the temple thread cutter by the cutting and holding devices which operate at transfer. Upon every movement of the lay the cutters lb are withdrawn into cooperative relation with the stationary blades 11 thus severing the filling end; By reason of the fact that an added stationary blade 11 is elosely adjacent to the end of the temple roll the severance of the thread will take plaee at a. point as near the salvage as is possible and by reason of the fact that there are a plurality of stationary blades coiiperating with a plurality of movable blades the severance of the filling upon the first beat up ol. the lay is assured so that not only a neater web of cloth is produced but the likelihood of a broken end of filling being drawn into the web of cloth by reason of the improper operation of cutters is avoided.

It is of course understood that this operation of the temple thread cutter occurs justprior to the time the lay engages the heel 31 of the temple and just before the regular running filling thread is beaten in so that the temple thread cutter cannot catch the thread but is always in position to sever upon the first pick after transfer, the filling end which extends from the selvage to the filling holder.

It is to be understood that this invention is not limited to the particular construction herein shown but may be applied to any other suitable form of loom temple.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A temple-heiul provided with a toothed roll and having a plurality of stationary blades one of which lies closely adjacent to the end of said temple roll, and forms a guide for the edge of the selvage of the cloth, a coiiperating movable cutter having a plurality of cutter blades alternating with said stationary blades and means for actuating said movable cutter whereby certain of the mo 'able blades will pass between said stationary blades in cooperation with the adjacent edges of the successive stationary blades.

A temple-head provided with a toothed roll and having a transverse slot at its outer end. a plurality of stationary cutters fixedly secured in said slot, one of said cutters being closely adjacent to the end of said toothed roll, and forming a guide for the edge of the selvage ot' the cloth. an oscillating and reciprocating cutter having a plurality of hooked blades disposed in alternating relation to said stationary blades, the edges 'of said movable blades cooperating with adjacent edges of said stationary blades and means for actuating said movable cutter.

In testimony whereof, I have signed my name to this specification.

WILLIAM R. W IDDUP.
