ADJUSTABLE RECEIVER FOR SPENT BOBBINS Filed April '17, 1946 INVENTOVR YRICHA 0 6. TURNER OM TW ATTORNEY Patented July 8, 1947 ADJUSTABLE RECEIVER FOR SPENT BOBBIN S Richard G. Turner, Worcester, Mass, assignor to Crompton & Knowles Loom Works, Worcester, Mass, a corporation of Massachusetts Application April 17, 1946, Serial No. 662,876

9 Claims.

This invention relates'to improvement in the collection of spent bobbins in weft replenishing looms and it is the general object of the invention to provide means by which the path of the outgoing bobbin may be altered to correspond to adjustments in the position of the bobbin collector or receiver.

In bobbin changing looms it is customary to eject the depleted bobbin downwardly from the shuttle and guide it alon a chute toward a spent bobbin receiver. Because of variations in the size and adjusted positions of different parts used on a loom which are close to the bobbin receiver the latter cannot always be kept in one fixed position. The bobbin chute is ordinarily permanently fixed to the lay and as heretofore made has caused the ejected bobbins to move along a more or less fixed path, with the result that if the receiver is moved outwardly from the loomside its mouth will not be in position to receive the descending bobbins. It is an important object of my present invention to provide the bobbin chute with an adjustable bobbin guide which can be altered depending upon the position of the receiver so that th descending bobbins will be directed into the mouth of the receiver.

Weft replenishing looms ordinarily employ some form of bobbin transfer mechanism mounted'on a horizontal stud. This stud is so located that it can conveniently support a bobbin receiver, but in certain types of looms the stud also supports other mechanisms, such as a weft detector or a thread cutter. These latter mechanisms require adjustment for their own correct operation, and the bobbin receiver must be so located as to permit these adjustments. It may therefore be that under one set of condition the bobbin receiver can be relatively close to the loomside, but under different conditions due to adjustment of one or another of the parts supported by the stud it will be necessary to move the receiver outwardly from the loomside. In order that the ejected bobbins may always be directed toward the mouth of the receiver regardless of the adjusted position of the latter it is a more particular object of my invention to provide an angularly and preferably horizontally adjustable bobbin guide located on the chute to engage the butt of the bobbin and alter the path of the bobbin to correspond to the location of the receiver.

With these and other'objects in view which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth.

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

Fig. 1 is a front elevation of part of a weft replenishing loom having my invention applied 7 thereto,

Fig. 2 is an enlarged front elevation of part of the structure set forth in Fig. 1 and indicating the manner in which the bobbinguide is adjusted on the bobbin chute when the position of the receiver is altered.

Fig. 3 is a side elevation looking in the direction of arrow 3, Fig. 2,

Fig. 4 is an enlarged section on line 4-4 of Fig. 3, the receiver being omitted, and

Fig. 5 is a side elevation of part of the structure shown in Fig. 1 looking in the direction of arrow 5, thereof.

Referring particularly to Fig. 1, I have shown a loom frame H3 and a lay ll having a shuttle box 52 to receive a shuttle S. A bobbin transferrer arm is is mounted on a horizontal stud l4 substantially parallel to the lay and held in fixed position on the lower part of the magazine designated at M. The stud I4 is in fixed position and supports the hub I5 of the transferrer arm. In addition, the stud may also support other instrumentalities, such for instance, as a weft detector D and a thread cutter C. These latter mechanisms of themselves form no part of my present invention, but for correct operation may require a certain amount of adjustment along the stud Hi.

Extending downwardly from the box I2 is a bobbin chute 20 bolted as at 2! in fixed position on the lay and inclined downwardly and forwardly. This chute is in such position that when the transferrer arm l3 expels a depleted bobbin fromthe shuttle S the bobbin will descend along the chute 20 and be guided in a generally forward direction.

The bobbin receiver designated generally at It includes a skeleton frame F which may be made of a single piece of metal bent as indicated in Fig. 1 to have right and left side members 22 and 23, respectively, and rearwardly extending arms 24, see Fig. 5. A bag 25 which may be made of cloth or other flexible material is supported by the frame F and is open at its upper end to define a mouth 25 to receive the descending bobbins.

As shown in Figs. 1 and 5 the receiver R is supported by a hanger H'having upper and lower members it! and Bi, respectively, bolted together as at 32. The lower member 3| has slotted guideways 33 which receive cross bars 34 connecting the upper parts of the side members 22 and 23 of the frame F. The upper hanger member 39 has a hub held in adjusted position angularly' and longitudinally on stud M by means of set screws 36. By changing the position of the hub 35 along stud M to accommodate adjustments of the parts C and D, the receiver R will be located at any one of several different positions arranged in front of and parallel to the lay and at varying distances from the loom frame iii. As a result of the horizontally adjusted position of the receiver the mouth of the bag will under some conditions berelatively close to the loom frame and under other conditions will be farther from the loom frame. V

In order that the descending bobbins may traverse a path corresponding to the location of the receiver I provide a bobbin butt or head guide 40 comprising a plate or flange i! having 9. lateral lug 42 lying against the chute and receiving a bolt 43 which extends through an adjusting slot 44 extending horizontally in the chute 29 and holds the guide securely to the chute. By means of the bolt 43 the angular position of the guide 40 and also its position horizontally with respect to the chute can be altered. The flange extends forwardly from the chute and is below a fixed flange 45 integral with the chute.

As shown in full lines in Fig, 2 it is assumed that the bobbin receiver R is in a relatively left hand position near the loom frame. Under these conditions the guide 40 will be disposed as shown in full lines and the descending bobbin B will be directed toward the mouth of the bag 25 along a path suggested by full line arrow at. Ifit is necessary to move the receiver to the right as viewed in Fig. 2 to some such position as indicated in dotted lines. the guide All will be given a corresponding adjustment to assume the dotted line position. When in this latter position the de- 'scending bobbins will be directed toward the mouth of the bag along a'path indicated by dotted arrow b and will not strike the side of the bag as would be the case if the guide it! had remained in theposition shown in full lines.

While only two positions have been shown for the bobbin guide in Fig. 2, it will be understood that because of the slot to it will be possible to move the guide bodily to the right of either of the positions shown in Fig. 2. 7 It is not thought necessary to illustrate these various positions.

From the foregoing it will be seen that I have provided simple means by winch the bobbin guide of the chute can be altered to accommodate changing positions of the bobbin receiver. The

guide 48 can assume any one of a number of ad- 1 justed positions both angularly and horizontally with respect to the bobbin chute, and the path traversed by the descending depleted bobbins can be adjusted to accommodate the location of the bobbin receiver. The receiver R, and hanger H are not claimed herein, since they form the subject matter of my copending application Serial No. 657,273 filed March 26, 1946.
