Application led April l, 1904'. Serial No. 201,031. (Nc model.; y

T 0 all whom/.it may concern:

Be it known thatI,EDMoND GU'ILBERT. a citizen of the United States, residing at Woonsocket, in the county of Providence and State of Rhode Island, have invented an Improvement in Loom-Temples, of which the follow.

ing description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

If in the operation of a loom the temple- Y head is improperly positioned, so as to hit the reed-as, for instance, if the heel of the temple loosens-the intermitting and rapid engagement of the reed-dents with the templehead will very quickly damage the dents.

My present invention has for its object the production of means which will prevent damage to the reed if the temple-head is so positioned as to be likely to strike the same as the lay beats up. To this endthe temple-head is provided with a normally inoperative fillingparte'r-a sharpened cutting-blade in the present embodiment of my invention-a spring acting to maintain the iilling-parter inactive unless for some reason the temple-head is liable to strike the reed. When such liability occurs, the reed acts to move the parter against its spring and between adjacent reeddents, cutting the running filling, the yielding of the spring preventing immediate damage tothe reed, while the cutting of the running filling will, through the usual lling-fork, cause'the stoppage of a common loom. If the loom is provided with automatic lling-replenishing mechanism, such mechanism would be operated a predetermined number of times, each new running filling being cut,;an'd then the loom would be automatically stopped or the continual cutting of the filling would cause the weaver to notice the effect on the selvage and he would know that the temple had become misplaced and stop the loom.

The various novel features of my invention will be fully described in the following specification and particularly pointed out in the claims appended thereto. Y

vFigure l is a side elevation of a portion of a temple embodying one formof my invention with a lay in section and showing the reed. Fig. 2 is a greatly-enlarged elevation of the temple-head as viewed from thc back of the loom. Fig. 3 is a transverse section on the line 3 3, Fig. 2, the thread-parter and its spring being shown in elevation and in normal position; and Fig. 4 is a side elevation of the temple-head, showing the thread-parter as in operative position to sever the running shuttle.

The temple, comprising the shank A, slidably mounted in the stand A', adapted to be secured to the breastbeam of the loom, the temple-head, comprising a pod B, cap B', and toothed roll B2, and the heel B3,`adjustably connectedwith the pod by screws bx, Fig. 1, may be and are all of welll-known construction, the

temple being set so that the lay A3 will engage Y the heel and push the temple toward the breastbeam as the lay beats up. At such time the dents R of thc reed will not strike the templehead; but if the heel should become loose and cause the temple to be misplaced ythe reed would strike the temple-headon each forward beat 'and very quickly bend or breakthe reeddents. My present invention isdevised to prevent damage due to displacement of the temple.

Referring more particularly to Figs. 2 to 4, the temple-head is provided with a transverse upright slot 1 at its outer end beyond the adjacent end of the roll B? to receive a parting-blade 2, fulcrumed in the slot on a pin 3, driven into a hole Li in the end of the cap and crossing the slot. The bladeis fulcrumed near its upper end, as shown, said end being enlarged. to form a head 5, provided on its outer face with a lateral enlargement 6, constituting a bunter. Behind the head `5 the cap Bl has a socket 7, (see Fig. 3,) in which is seated a coiled spring 8, the outer end of said spring bearing against the head 5 of the parting-blade, the expansive action of the spring projecting the bunter 6 beyond the face of the temple-head and retracting the greater portion of the blade'Q into the slot 1.. This normal position of the blade is clearly shown in Figs. l and 3, and it will be observed that the slot serves to house the blade, so that it cannot engage the running filling as the lay beats up. At such time the reed-dents cannot engage the bunter, provided the temple is properly positioned and acted upon by the lay. lf the temple is displaced, however, the reed-dents will engage the bunter 6 and press it in against thespring 8, rocking the blade and projecting it in front of' the temple-head, the blade passing in between adjacent reeddents, as shown in Fig. 4. Such swinging;

movement of the blade carries its cutting edge 9 across the path of and severs the running filling, (indicated at Fig. 4,) the spring 8 also serving to cushion the blow of' the reeddents and preventing immediate damage thereto. If the apparatus is on a common loom, the severing of' the filling will act through the usual filling-fork to stop the loom, and the weaver can at once remedy the fault.

The invention is equally applicable to looms provided with automatic filling-replenishing mechanism, as such looms are usually so constructed as to be stopped automatically upon breakage of the running filling or to be stopped after a predetermined number of successive filling replenishments.

My invention is not restricted-to the construction shown and described, for, so far as I am aware, it is broadly-new to provide a loom-temple with means to part thc running filling, and accordingly various changes or modifications may be made by those skilled in art without departing from the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A loom-temple, and means carried thereby to part automatically the running filling' when the temple becomes misplaced.

2. A loom-temple, means carried thereby to part automatically the running filling' when the temple becomes misplaced, and aspring to normally maintain said means inoperative.

3. Aloom-temple, means' carried thereby to part automatically the running filling when the temple becomes misplaced, said means including a bunter adapted to be engaged by the reed, and a spring to normally maintain said means inoperative and to cushion the bunter when struck by the reed.

4. A loom-temple having a head, a fillingparting blade movably mounted thereon and provided with a bunter, and a spring to nor- 5. A loom-temple having a head, provided with a transverse slot at its outer end, aparting-blade fulcrunned in said slot and having a bunter, and a spring to normally retract the l'blade within the slot and to position the bunter to be struck by the reed if the temple is misplaced, to project the blade between the reeddents and sever the running filling.

6. A loom-temple havingahead containing a roll and provided with a transverse slot beyond the outer endA of the roll, an upright parting-blade fulcrumed to ,move in and out of theslot, a laterally-enlarged bunter carried by the blade above its fulcrum, and a spring to normally project the bunter and maintain the blade housed within the slot. V

7. In a loom, a lay provided. with a reed,l a temple having a transversely-slotted head, an upright parting blade fulcrumed thereon within the slot, a projecting and laterally-enlarged bunter on the blade above its Jfulcrum, and a spring to normally maintain said blade housed and the bunter extended beyond the head, misplacement of the temple permitting thereed to strike the bunter as the lay beats up, to .swing the blade across the path of the running filling and between adjacent reeddents, to sever the -filling. 1

8. In a loom, a lay provided with a reed,.a temple having a head provided with a heel adapted to be engaged and. retracted by the lay on its forward beat, an upright partingblade fulcrumed on the temple-head, an attached bunter on the blade, and a spring to normally maintain the bunter projected beyondy the head and the blade retracteden gagement of the bunter by the reed upon misplacement of the temple compressing the spring and swinging the blade between adjacent reed-dents across the path of and to sever the running filling.-

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

-EDMoND GUILBERT.
