THREAD-CUTTING TEKVIPLE FOR LOOMZSJ Application filed October-9, 192 0. Serial no. 415,743.

a specification, like characters on the drawing representing like parts.

This invention relates to improvements in thread cutting temples for looms and the object of the invention is to provide a con struction in which the journal pin for the temple roll does not extend across the path of the cutter, and in which the selvage end of the temple roll is closely adjacent to the cutter, thus to enable the cutter to operate close to the selvage of the cloth.

The objectof the invention is secured by providing a thin separating wall integral with the temple head between the cutter recess and the roll recess, which shall be sufficient to support and steady the selvage end of the roll pin and still permit the selvage end of the roll to be closely adjacent to the cutter, and by supporting and securing the other end 0 the roll pin, preferably by a threaded section, in the end wall of the head.

It the roll pin extends across the cutter recess it is a simple matter to support and secure the roll pin in position, but as the moving parts wear the movable cutter blade not infrequently comes into contact with the roll pin projecting across its path causing injury and damage to both, and interfering with the accuracy of the operation of the device. If the separating wall between the cutter recess and the roll recess is provided of a character sufficient to secure in position the roll pin it is necessarily of such thickness as to remove the selvage end of the roll a substantial distance from the cutter, which is undesirable because it interfere with the accurate cutting of the filling ends adjacent to the selvage of the cloth. In the present invention the roll pin is both supported and secured in position by the threaded connection in the end of the temple head, while the selvage end of the roll pin is supported and steadied by a thin separating wall which still allows the selvage end of the roll to be closely adjacent to the temple cutter.

These and other objects of the invention will appear more fully from the accom panying description and drawings and will beparticularly pointed out in the claims, In the drawings: 1 v l Figure l is a plan view of a temple em bodying a preferred form of the invention.

Figure 2 is an elevation of the construction shown in Fig. l. i t I Figure 3 is a vertical sectional view taken on line 3-3 of Fig.2. I

The general construction and purpose'of a temple and temple thread cutter for looms is so well known to those familiar with the weaving art that it is unnecessary to set the same forth in anything more than a general way, t j I I These temples are mounted, usually on the breast beam of the loom, one at each edge. of the cloth and act to stretch the cloth to and maintain it at the proper width while the temple thread cutters, associated therewith, act to sever close to the selvages the filling ends extending therefrom.

The general construction of temple "and temple thread cutter illustrated in the drawings is of a familiar type, a temple for the ri ht hand side of-the loom being shown.

The temple stand 1 which is bolted to the breast beam is shown partially broken away. The temple head2is carried bythe usual bar or shank 3 slidable in the temple stand. This head 2 comprises a laterally projecting hollow cap l, and beneath a laterally projecting pod 5, the space between the cap and the pod opening toward the center of the loom. The temple roll thus is journalled inithe recess 7 provided by the hollow cap, and is provided with some form of projections or teeth 8 usually arranged in helical series about the periphery of the roll so that as the cloth is fed during the weaving operation through the temple, this roll acts to stretch the cloth toward the side of the loom upon which the temple is mounted.

The temple thread cutter is also shown as of a familiar type. As illustrated it, comprises a fixed blade 9 mounted vertically in the recess 10, and a pair of movable blades 11 movable in the recess 10 and projecting from a shank 12. The shank 12 is provided with the usual depending heel 13, and is projected rearwardly by the usual spring 14. As the lay beats'up it strikes the heel 13 the head of the temple. This separating wall is only of sufficient width and strength to support the selvage end of the roll pin 15, and consequently it enables the selvage end of the roll to be brought up closely adjacent to the cutter. This roll pin upon which the temple roll is journalled is supported at its inner end in the end wall 16 of the head and it is entirely secured'in position in this end wall. There is no objection to making the end wall of any desired thickness, and consequently a threaded section 17 or substantial length may be provided on the roll pin 15 and a corresponding threaded socket provided in the head end wall 16. It will be seen therefore that when the roll pin 15 is in place it is securely held by the threaded engagement of the section 17 in the end wall 16, and that it is suiliciently supported and steadied atits selvage end by the thin separating wall 14.

This temple roll is suitably journalled without the roll pin crossing the path of the cutter, and at the same time the selvage end of the roll is closely adjacent to the cutter.

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

1. A thread cutting temple comprising a head having laterally adjacent cutter and roll recesses, the wall separating the said recesses and the end Wall of the roll recess both being integral with the head, a thread cutter mounted in the cutter recess, a temple roll mounted in the roll recess, a roll pin extending through and journalling the temple roll, the said roll pin being terminally supported but not secured at its selyage end in the supporting wall and the said Wall being of sufficient thickness only to serve as such support, the said roll pin at its opposite end being supported and also se-' cured and held in position in the end wall and the said end wall being of sufficient thickness to provide the sole means for se curing and holding the roll pin in position, whereby the integral separating wall is relatively so thin as to allow the selvage end of the temple roll to be closely adjacent to the cutter.

2. A thread cutting temple having the construction defined in claim 1 in which the inner end of the roll pin is threaded and the end wall of the temple head is correspondingly threaded removably to secure in position the roll pin.

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

ERNEST A. GAGNON.
