y latch.

rlhe usual multicolor magazine has provision for storing several parallel vertical A stacks of bobbins each of which is controlled by a vertical slide. When the weft detector vindicates, weft exhaustion the Vslide corresponding to the active shuttle is raised, and

when the same shuttle is again under the magazine on a later pick the raised slide is depressed. In its downward movement the slide rocks a device which moves the shuttle feeler into shuttle detecting position and also raisesv the transferrer latch so that the latter is in the path of a bunter on the lay. In previous constructions the latch lifting device has been made in several parts and has included a knuckle joint having in its construction a lever the effect of which is to raise the transferrer latch by an upward movement. It is an important obj ect of my present invention to simplify the aforesaid device and to eliminate the reversing lever so that the Y latch may be raised by fewer parts.

It is a furtherobject of my present invention to place the knuckle joint in a more convenient position where it mayfact centrally with respect to the vertical slides7 the shelf or portion of thedevice which cooperates with the slides beingdivided to make room for the knuckle joint. It is a more specific object of the invention to form the magazine frame so that it will cooperate with the simplified joint so as to limit the latter in both directions and aord a seat for a portion of .the joint. n

It is a further object of ymy present invention to place the spring which acts to yieldingly lock the rockinP device at a point intermediate-the bearings of the latter so thatin `case of wearinguniform clearance will exist between vthe Shelves yof the rocking member and the vertical slides.`

With theser and other objects in view which will appear as the description proceeds; my

-invention"resides in the combinationV and arrangement of partshereinafter described and set forth in the claims.

In the accompanying drawings wherein a convenient embodiment of my invention is set forth,

Fig. 1 is a side elevation taken from the interior of the' loom showing the multicolor magazine having my invention applied thereto,

F ig. Qais a horizontal section looking down along the line 2 2 of Fig. 17

Fig. 3is a detailed vertical section on line 3 3 of F ig. 2 showing the knuckle joint in two different positions, and

Fig. 4 is a vert-ical section on line 4 4 of Fig.2.

Referring particularly to Fig. 1, l have shown the loom vframe 10 supporting a foot 11 of the magazine M. A transferrer lever 12Vis` pivoted as at 13to the foot and has a depending arm 14 to which is pivoted a. latch carrier 15. The latter may be secured in any approved manner to the holder and is adapted for cooperation'with the bunter 17 on the la L.

lll shuttle feeler 18 yis pivotally mounted to move about a stud'19 in a vertical direction and is depressed byy means of an upright rod 20 whenever transfer is about to take place. lNhen in lowposition the shuttle feeler detects for the correct boxing of the shuttle S and if the shuttle is misplaced it will raise the feelery and through mechanism to be described will effectlowering of the latch 16 to prevent transfer.

The color slide designated herein as at 21v has longitudinal and angular movements and is proportioned to cooperate with thevertical slides 22, 23, '24 and 25'which entend,

respectively, from the front to the rear of the magazine. The color slide is under con fill The matter thus far described is of common construction and forms no part of my presentinvention. For a more complete understanding of the construction in operation, however, reference may be had to prior patent to Ryon No. 1,030,748.

In carrying my invention into effect I provide improved connections between the rod 2O and the latch 16, said connections including an improved rocking member for cooperation with one or another of the vertical slides. The magazine frame has extended therefrom toward the center of the loom a pair of horizontal arms 30 through which extends a pin or shaft 31 substantially parallel to the color slide 21. A set screw 32 may be employed to hold the shaft in position in the arms. The rocking member 33 has spaced hubs 34 and 35 which lie, respectively, behind and in front of the arms 30. Extending from the hub 34 and lying between the pin 31 and the magazine is a linger 36 operatively connected to the upper end of the rod 20. A short shelf 37 is also cast integral with the linger 36 and is adapted for cooperation with the rear slides 24 and 25.

The front hub in like manner has extending therefrom a somewhat longer linger 3S which is pivotally connected to the upper end of a depending rod 39 the lower end of which is operatively connected as at 40 to the latch holder 15. second shelf 41 similar to shelf 37 extends from the finger 38 to cooperate with one or another of the vertical slides 22 and 23. The shelves 37 and 41 have upper surfaces 42 to cooperate with the dogs 27 pivotally connected to the vertical slides.

In operation it is necessary that the rocking member move from one to another predetermined angular position, and in order to elliect this movement I cast on the rocking member an auxiliary bearing 44 through which the pin 31 extends. This bearing eX- tends toward the magazine and is forked as at 45 to receive a pin 46. A plunger 47 has a reduced end 48 lying between the forked end of the bearing 44 and pivotally connected thereto by the pin` 46. A shoulder 49 on the plunger receives the thrust of a compression spring 50 the other end of which bears against a washer 51.

As shown in Fig. 3 the washer is restrained as to movement to the right by means of a web 52 extending between flanges 53 and 54, respectively. These ianges are of the usual form except for the bridge 52 and assist in delining two of the four bobbin compartments C shown. The bridge may have a convex surface 55 over which the washer 51 slides and is perforated as at 56 to permitpassage therethrough of the plunger 47. Cast integral with the frame of the magazine and extending above and below the rod 47 are stop lugs 57 and 58, respectively.

These lugs are positioned to engage the auxiliary bearing to limit angular movement of the rocking member.

Under normal conditions the rocking member will be in the position shown in full lines in Fig. 3, the spring 50 holding the bearing against the upper stop lug 57. Then a previously lifted vertical slide moves down preparatory to transfer it will engage one or the other of the shelves 37 or 41, rocking the member 33 in a clockwise direction as viewed in Fig. 3 around the pin 31 so that said member and the rod 37 will assume the dotted line position shown in Fig. 3. rlhis movement causes a depression of rod 20 to move the shuttle feeler 18 to a shuttle feeling position and also causes a lowering of rod 39 which eliects lifting of the rear or left hand end of the latch 16 as viewed in 1* 1 into the path of the bunter 17. During the latter part of the forward movement of the lay the shuttle feeler will be moved upwardly by the box back B, thereby restoring the rocking member to its normal position.

From the foregoing it will be seen that I have provided a very simple construction wherein the shelves 37 and 41 are spaced to provide room for the knuckle joint, thereby using space which has heretofore been unused in magazines of the multicolor type. It will further be seen that the spring` 50 bears against a small web which extends between the flanges 53 and 54 and it will also be noted that the stop lugs above and below the knuckle joint are of simple form and elfectively limit angular movement of the rocking member. The action of the spring 50 is distributed equally between the hubs 34 and and an wearing which may result in the turning o the member 33 on the pin 31 will be uniform, the spring holding the shelves at equally spaced distances from their corresponding vertical slides. It will also be seen that the construction is such that a single set screw 32 is suflicient to hold all the devices in proper longitudinal position. Furthermore, it will be noted that the reversing lever of previous constructions has been eliminated, the control of the latch being more direct in the present instance.

Having thus described my invention it will be seen that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention and I d-o not Wish to be limited to the details herein disclosed, but what-I claim is:
