Application filed Novexnher 24, 1923. Serial n1 576 522,

To all whomit'may conoema t i Be it'known that I, OsoARfW.j RIoH RD- soN, a citizen of the United States, residing atwWorcester in the county of Worcester and State of @assachusetts, have invented a new anduseful Transfer Controller 5 for Weft-Replenishing Loom's of which the followi'ngis a specification. v This invention relates to weft replenish- 'ing looms and 1 9 1 ,,pgrtioularlyito the. control" forthe transfer mechanism by means of whicha; fresln bobbin is inserted in ,the active shuttle, I

In the typ eiof loom illustrated in United States patent to Rvon No, 9335492, the. replenis'h'ing I'nechanismj comprises a transfer arm to the lower end" of "which is pivotally connected; a transfer-latch, When a change is indicated thella tch' is raised into the path v of "a hunter on the lay by, means 'of,!connectomove it toa saferposition.

tions from the top shaft of th'e weftzreplenishing; mechanism; The connector between the top shaft and therlatchj is similar to that shown inBatent No. I,O 2 2",108", the lower end of the connector being guided bya stud j 'fi'x ecl' to some stationary party of the loom above the transfer latch. The connector and its cooperative studfare so idesignedjthat' th'eformer has a verticalmovement and is as near the shuttle .boxiinits lower as in lts upper position.

of the magazine, the bobbin which should be transferred 1 becomes 7 misplacedf andflies' between the lay andg the aforesaid connector.

The connector is so close; to the'lay that under such conditions either the bobbin" or somepart of the replenishing mechanism is likely to be broken.

latter assumes normal, position after transfer the latch moves downwardly and; also forwardly, The latch controller at. this time has a downward motion only. and does not have a corresponding 'forwardmotion With, a view to, overcoming these tions Ihave provided means whereby the guide for, the controller i's looated below the latch and in sueh a osi'tionthat it is not likely to be strnckhyg hone: n s .f r most'po itiqn;

gaging a part of the replenishing mechanism to m ovem n he p rt 'latch 25 isbolted to; the holder L6 and-1s in operative relation with the lower end of a l latch controller 26 v the upper end. of which is pivoted tothe lever 21 as at 27. l/Vhen weft replenishment is to occur, shaft 17 is turned in a clockwise direction as viewed in Fig. 2, connector 26' is raised and the latch 25 is moved to the dotted lineposition shown in Fig. 1. As the lay advances, the bunter 28 formed thereon engages the latch to dewith. oppositely extending fingers 32 which areso placed as to lift the latch when the controller. israised. Extending fromthe head 31 is a cam projection 33 having. a

steep and substantially vertical cam portion 34 near the end thereof and a shallower cam portion: 35 located between the, face 34 and the fingers 32; A'fixed guide block 36 has a bolt and slot connection. with some'sta tionary part'of the loom by means of which it may be adjusted. V

Innoperation the parts normally assume the fullline position shown in Fig. 1, but when transferyis called for the partsmove as previously described to raise the latch to the dotted line position, this raising of thelatch being effectedby means of fingers 32 engaging the under side of latch 25. As-the lay advances, the hunter 28 engages the latch 25 and moves the latter forwardly, the.

' latch controllerbeing in theposition shown in Fig. 3 with the steep cam face 34 in contact with the guide 36. As the lay advances the curved under face 37 of the late-hengages the fingers 32 to depress the controller and the substantially vertical face 34 cooperates with the block 36 to effect a rapid lowering of the controller.

' he knuckle o1nt connectors shown in 2and the upper end of face 34 are so arranged that as the face 34 is about to leave guide 36 the spring 23 will act to lower the controller and move the latter to the position shown in Fig. 4. The cam face 35' is. much shallower than the face'34 and as the controller descends, it is permittedto I move forwardly toward the guide 36 by reason of the fact that the pivotal connection.

27 between the controller 26 and the lever 21 is forward of the head 31 when the latter is in its foremost position. 7

When the lay moves back and hunter 28 releases latch 25, the latter. falls to the position shown in Fig. 1, the fingers 32 being engaged by the faces 37 to force the head 31 forwardly under the weight of the controller. Itwill be noted from an inspection of Figs. 1'- and 3 that the front end of slot 30 in the latch is farther forward 'When' the latch is'down as in Fig. 1 (full lines) than it is when raised-as in Fig. 3, thus permitting the controller head 31 which passes through the latch to remain in forward position when the latch isrestored to normal position from the position-shown in Fig. 4. Also itwill be seen that the controller moves to its foremost positionon the transferring pick because of the fact that thelatch has been moved forwardly at that time. I

From the'foregoing it will be seen that I have provided a fixed guide below the latchfor cooperating with the latch controller, 1

that the controller has a combined forward and downward movement, that the latch ,is slotted to receive the latch controller sothat the latter is restrained against undesirable lateral motion, and that when the latch is in lower inoperative position vit serves to hold the controller in forward position.

Having described one' form 'of my'invention, it will be apparent that changes and modifications may be made therein by those skilledin the art and I do not wish to be limited to the specific structure illustrated, but what I do claim is:

1. In a weft replenishing mechanism for a loom having a lay, a transfer, a latch V pivotally connected thereto, a controller for said latch normally in forward position away from the lay, and means to give sa d controller an upward and. rearward movement prior-totransfer to raise the latclr and:

a downward and forward movement during transfer to restore said controller to forward position away, from the lay.

2. In a weft replenishlng loom,'a transfer arm, a. latch pivotallyv connected thereto, a

controller for'said latch operatively .con-

controller during transfer, and means to give said controller a rearward movement as it is raised and a forward'and downward mot1on to restore the same to normal position as-the replenishing mechanism is reset.

4. In ,a Weft replenishing mechanism, a transfer .arm','.a latch pivotally connected thereto, a cont-roller .for said latch, fixed means cooperating the said'controller, said controller having cam portions to engage the fixed means to cause said controller to have an initial rapid downward motion followed by a forward motion: 7

5. In a weft replenishing loom, a transfer arm, a transfer latch pivotally connected to the arm and having a slot therein, a latch controller 'operatively connected to the re plenishing mechanism and having a portion thereof extending through. the slot in the latch to restrain lateral displacement of said controller, said controller to lift the latch at the time of transfer.

6. In a replenishing loom having a lay with a hunter thereon, a transfer arm, a

-' member pivotally connected to the transfer arm to engage the hunter on the lay, and a control member for said first named member,

controller for said latch operatively conv nected to the replenishing mechanism, a

guide for said controller, and means on the controller for giving the latter a forward and downward motion during replenishment, said latch engaging said con- 7 troller to hold the latter in foremost position when the latch is in operative position,

In testimony whereof I have hereunto affixed my signature.

OSCAR W. RICHARDSON.
