Patented June 6, 1933 UNITED STATES PATENT OFFICE -FREDRIG E. DOUGLAS, 01: HOPEDALE, MASSACHUSETTS, ASSIGNOR TO DRAPER COR- PORATION, OF HOPEDALE, MASSACHUSETTS, A CORPORATION OFMAINE LOOM TEMPLE Application filed June 10,
The present invention relates to thread cutting temples for looms.
It is now common practice to provide automatic filling replenishing looms with mechanism for trimming the out-going and incoming filling ends adjacent the selvage, in order that the cloth may not have such ends projecting from the selvage at each place where the filling replenishing operation occurred. Such mechanism is customarily mounted in the temple on the magazine side of the loom and usually includes a ledger blade with which co-operates a rocking and sliding cutter blade operated by the lay.
Since the movable cutter blade is moved forwardly by the lay, it is necessary that it be rocked bodily to hook its depending cutting edge behind the filling before beginning the forward movement. Probably the most 217i satisfactory of the movable cutter blades heretofore devised is comprised of a body, or carrier, a depending tail piece and a cutting tip, all cast integrally in one piece, the device being positioned in a comparatively large slot T in the temple. Whilesuch device is reasonably eflicient from the standpoint of initial and maintenance costs itis, nevertheless, inherently more or less haphazard in operation, due to the fact that it is not positively guided 301 in all its movements.
It is accordingly, the principal object of my invention to provide a thread cutting temple wherein the movable cutting member is comprised of a rockable and slidable cutting i tip and a rectilinearly slidable carrier having means for positively controlling the cutting tip during all its movements.
A further object of my invention is to pro vide, in a thread cutting temple, a rockable and slidable cutting tip and a slidable carrier operating to first rock the tip to hook it behind the filling and then slide it forwardly past the ledger blade.
H Other objects of my invention will, in part,
431 be hereinafter more specifically enumerated and will, in part, become obvious as the description proceeds.
Referring to the accompanying drawing, which illustrates the preferred embodiment of my invention:
1932. Serial No. 616,513.
Fig. 1 is a front elevation of a thread cutting temple embodying my invention;
Fig. 2 is a sectional elevation, taken substantially on line 22 of Fig. 1; and
Figs. 3 and 4 are views similar to Fig. 2 but showing different relative positions which the parts assume during the cutting operation.
The temple to which my invention has been applied, as illustrated on the drawing, is of standard construction except for the thread cutting mechanism. Such temple includes a bar 1 adapted to be yieldingly mounted in a guideway on the breast beam (not shown) and carrying a head 2 which includes a cap 3 and pod l housing suitable means such as rollers 5 for gripping the cloth adjacent its selvage, a guide 6 being provided for abutting the selvage should it tend to creep too far toward the left in Fig. '1. The temple head is provided with a depending heel 7, adapted to be struck by the lay, or a hunter thereon, for reciprocating the temple in the usual manner.
The thread cutting mechanism is, in the particular construction shown. on the draw ing, comprised of a ledger blade 8 positioned at the rearward entrance to the guideway 9 in the temple head, rockable and slidablecutting tip 10, and a carrier for the tip, comprised in the present instance of a bar 11 and a yieldable stop 12.
The cutting tip is provided at its rearward end with a depending head 14 having its forward edge sharpened to co-operate with ledger blade 8 in cutting the filling. At the forward end of the cutting tip are diverging prongs 15 and 16. The upper prong, 15, is provided with a substantially cylindrical surface engaging in a correspondingly shaped recess in stop 12, this providing a pivotal connection between the tip and the stop. The lower prong, 16, engages in an upwardly opening recess 17 in the bar 11.
The bar 11 is shown as being rectangular in cross-section, and is confined in the bottom half of the guideway 8 so as to be movable rectilinearly in the direction of its length. The bar is provided at its rearward end with a downwardly and rearwardly inclined surface 18 adapted to limit the angular movement of the cutting tip in one direction. The forward end of the bar is formed integrally with the depending heel 19 which is adapted to be struck by the lay, not shown, to move the carrier forwardly.
The stop 12 is, in the present instance, likewise movable only rectilinearly, in the upper half of the guideway S. The stop is provided with an upwardly and rearwardly inclined surface 20 complementary to surface 18 on the bar, and is also provided with a laterally extending lug 21 adapted to engage the temple head to limit rearward movement of the stop.
The parts normally occupy the positions shown in Fig. 2. hen the lay first strikes heel 19 the entire carrier does not move forward, but only the bar 11, stop 12 remaining stationary under the influence of arm 25 of the spring. Thus, the initial movement causes the tip 10 to rock about its pivotal connection 15 with the stop, to hook behind the filling, the parts then assuming the positions shown in Fig. 3.
hen the cutting tip, in its rocking movement, encounters surface 18 further angular movement is prevented. The prongs 15, 16 then form a'rigid connection between bar 11 and stop 12, and the entire carrier moves bodily forward, carrying the cutting tip with it to draw the cutting edge of the latter past the ledger blade 8, as shown in Fig. 4.
Attention is particularly directed to the fact that in the present construction, while the cutting tip has both rocking and sliding movements imparted to it in the requisite sequence, the carrier proper is movable only forwardly and rearwardly, preferably in a straight line, and the sequence of the move ments of the cutting tip is positively controlled. The particular manner in which this and other desirable results are obtained may, of course, be varied within the scope of the appended claims without departing from the spirit of my invention.
Having fully disclosed the preferred embodiment of my invention, I claim:

A thread cutting temple for looms, comprising a temple head having means for gripping the cloth adjacent its selvage, and a thread cutting mechanism immediately adjacent the said gripping means for trimming the filling ends projecting from the selvage, said thread cutting mechanism including a stationary ledger blade, a rockable and slidable cutting tip cooperating with the ledger blade, and a slidable carrier mounted in a guideway in the temple head and confined thereby to rectilinear movement only, said carrier having means for first rocking the said tip to cause it to hook behind the filling and then sliding the tip to draw it past the said ledger blade.
