THREAD-PLACER.

Application filed August 18, 1916.

To all whom it may concern:

Be it known that I, ALFRED I MORELL, a

In this type of looms, after the operation of the transfer mechanism, a portion of weft extends from the selvage toward the shuttle box, and it is necessary that this portion of weft should. be immediately severed and removed before it can be woven into the cloth. F or this purpose, a temple thread cutter is used and it is the object of my present invention to provide a device which shall cooperate with this thread cutter to insure the positive cutting of this outgoing weft. Q

With this object in view, one feature of my invention consists in the provision of a thread placer carried by the lay and adapted to be advanced relatively to the reed after the weft transfer, such movement positively presenting the outgoing weft to the action of the temple thread cutter. In the preferred form of my invention the thread placer is actuated indirectly from the transferrer arm, said arm beingetfective to move an actuator to operative position. Provision is also made for withdrawing said actuator after the operation of the thread placer. ihis latter mechanism is herein shown as under the control of the feeler mechanism and as adapted to withdraw the actuator after the secon'd operation of the thread placer. 1 also provide for the retraction of the thread placer as the shuttle and lay reach their extreme forward position, thereby avoiding engagement with the temple or temple thread cutter. I

My invention further 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 my invention is shown in the drawings in which Figure 1 is a side elevation of my im- Specification of Letters Patent.

Serial No. 115,609.

proved thread placer and the operating mechanism therefor, certain parts of the loom being shown in section;

Fig. 2 is a top plan view of parts of the mechanism shown in Fig. 1, taken along the line '2-2 in said figure;

Fig. 3 is a top plan view of additional. mechanism shown in Fig. 1, taken along the line 3+3 in that figure;

Fig. 4: is a detail sectional View taken along the line 1 l in Fig. 3, and

Fig. 5 is a longitudinal sectional view of the spring plunger which positions the actuator.

Referring to the drawings, 1 have shown a temple of the usual form mounted upon the breast-beam 11 and provided with a movable thread cutting element 12. The lay is indicated at 13 supported upon the usual sword 1 1 and provided with the usual reed 15 and hand rail 16. The shuttle 17 is indicated in its position on the lay.

The thread placer comprises an arm 20 secured to a shaft 21 in position to swing between two adjacent dents of the reed 15. The shaft 21 is mounted in bearings 22 and 23 formed on a bracket 2 1 secured to the sword 1 1. A coil spring 25 is fixed at one end to the bearing 22 and at the opposite end the shaft may be adjusted. Stops 27 and 28 cooperate to limit the backward movement of the thread placer 20. V A cam arm 30 is fixed to the opposite end of the shaft 21, and supports a double-faced cam 31 through which the thread placer is actuated.

I will now described the mechanism for moving the cam 31 and actuating the thread placer. A portion of a stationary weft magazine 35 is shown in the drawings, said magazine being provided with a rock shaft 36 mounted in fixed bearings on the magazine and connected to mechanism not shown from which the rock shaft receives motion on any alternate beat of the lay if the-feeler mechanism calls for a change in filling. For further illustration and a more complete description of thismagazine mechanism reference is made to the patent to Ryon, No. 1,030,748 issued June 25, 1912, the shaft 36 of this application corresponding to the shaft 36 of the patent.

An actuator 40 is mounted upon a fixed Patented Mar. 19, 1918. I

pivot ll carried by themagazine 35, and is provided with an extension 42" having notches i3 and 4% adapted to cooperatewith.

a spring plunger 45 by which means the actuator may be retained in either operative or inoperative position. The details of the spring plunger are clearly shown in Fig. 5,

the plunger being mounted in a fixed sleeve 46 carried by the magazine.

A stud 47 is carried by the actuator 40 and is movable with the actuator into the path of travel of the cam 31. For moving the actuator from its normal inoperative position to its operative position I provide a lug 50 upon the outer face of the 7 regular transferrer arm 51. As this trans ferrer arm moves downward to eject a substantially exhausted weft carrier, the.

. actuator is also moved downward until the stud 47 occupies the position shown in dotted lines in Fig. 1, in which position it is retained by the spring plunger 45.

As the lay continues its forward movement, the stud 47 engages the cam 31 and swings the thread placer forward to carry the outgoing weft into the path of the temple thread cutter 12. As the lay continues to move forward, the cam 31 passes beyond the stud 47 and the thread placer is retracted by the spring before it engages the temple 10 or its'thread cutter 12.

This operation of the thread placer is once repeated after which the actuator 40 is removed to its inoperative position. The devices for thus removing the actuator comprise a rod 52 threaded into a head 53 pivoted at 54: to a member 55, said member being loosely mounted on the shaft 36 and'be- 'ing actuated by a rod 56 preferably formed integral with the usual rocker 58 carried by the shaft 36. The rod 56 is freely slidable longitudinally through an opening in themember. 55. The threaded rod 52 at its lower end is offset to form a shoulder and engages a lug 60 upon the back side of the actuator A0.

The rock shaft 36 and the rocker 58 re-v ceive movement before the operation'of the transferrer arm 51, and the rod 52 is thus lowered to permit movement of the actuator A0 by the transferrer arm. The actuator re mains in operative position until the shaft 36 and rocker 58 are'restored to their inoperative positions, at which time the actuator 40 is also restored to its inoperative osition. I have thus provided a thread placer which is positively actuated by the transferrer mechanism and which is controlled 0091:: of this patent may be obtained for in its actuation by the weft detecting mechanism of the loom. The placer is arranged; to present thethread positively to the temple thread cutter while at the same time it is itself withdrawn beforeengagementtherewith can occur.

Having thus described my invention it will be evident that other changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope thereof as set forth in the claims, and I do not'wish to be otherwise limited to the details herein disclosed.

What I claim is 1. In aloom, a lay havinga reed, a temple thread cutter,'a-thread placer movable 3. In a loom, a lay having a reed, a thread placer mounted on the'lay and movable relatively to said reed, a transferrer arm, and connections between said placer and said transferrer arm whereby said transferrer arm controls the actuation of said placer.

4. In a loom, a lay, a' thread placer mounted thereon, a cam movable therewith, an actuator effective through said cam to give said placer an operative movement, means to move. said actuator to operative position relativelyto said cam,'means to thereafter return said actuator to inoperative position, and a spring effective to move said cam and placer 1n the reverse d1- rectlon, saldcam permitting such reverse movement of said placer during the continned forward movement of the lay.

5.111 a loom, a thread placer,- an arm secured thereto having a double-faced cam thereon, a cam stud to actuate said cam, an

arm supporting said stud, a spring plunger.

to hold said arm in a selected position, and feeler-controlled mechanism for moving said arm to operative and inoperative p0 sitions.

In testimony, whereof I have hereunto affixed my signature; r A
