Thepresent invention relates toshuttle chang ing looms operating with shifting shuttle boxes 52 and it is the general object of .the invention to provide-an improved magazine for the reserve shuttles.

It is another object of my invention to provide a multi.-cell magazine built up'of a plurality of substantially similar reserveshuttle units-which y can conveniently be arranged in parallel order to deliver shuttles Ito acarrier the path' of which is common to the units. In this-way I am enabled to increase the color capacity of the loom merely by' adding additional units-and increasing" the length of travel of .the carrier.

In this connection it is a further objectof the invention to provide each unit with a selector mounted on apart of the shuttle unit and arrange the-magazine so that escapement devices canbelocated between the units.

Itis a still further object of my invention to provide simpleand efiicient means to control the trailing weft ends of the reserve shuttles.

" several-.units orv stacksare so arranged that the weft endscan be led to athreadholder located to permit free movement of the shuttles of. any. stackwithout disturbing the weftends of any. other stack. The thread slotsof the several stacks: are positioned to accommodate threads extending :flOl'Il the shuttle delivery eyeswhichmay be located asin non-automatic looms, that is, with the shuttle eyes pointing-towardthe selvage when the shuttles areon the drop boxend of the v loom. Thisrelationrequires the shuttle eyes to beat the outerend of the shuttles when the lattenareat'the magazine end of the loom, and this ability to operate the automatic box loom with the shuttle eye located as on-the non-automatic 40' loom isa: novel and efficient feature of my invention.

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 claims;

The magazine forming the. subjectimatter of this invention employs: a plurality of shuttle stor-' ingiandwreleasingunits, one for each shifting 80f. shuttle box; There are-showntwo magazines 90 and 911 eachzmadexof: three sections.

The inner magazine frame 96 is'mounted" on the'end of the breast beam, while the outer-frame is suitably supported from-the floor, and *tie rods e5 rigid'andproperly spaced relation; 1 I

- the magazine.

Selector mechanism is employed to cause shuttle delivery to take place from the unit corresponding to the depleted weaving shuttle. Accordingly, each unit has a rock shaft 103 with control fingers 104 fastened thereto, see Fig. 2. The rockshafts are mounted in lugs 105 on the rearward sections 94 of the magazines, two fingers being used on each rockshaft. The fingers of each rockshaft are movable under the corresponding magazine to prevent delivery of the bottom shuttle.

The fingers are so moved that delivery can take place from but one unit at a time, namely, the one corresponding to the weaving shuttle to be ejected. This control is exercised by the box motion not shown, by means of a rod 112 which is reciprocated vertically by the shifting of the shuttle boxes, and is pivoted to an arm 113 fixed on the rear shaft 103, see Fig. 3. This last named shaft carries an arm 114 having a pin and slot connection with a similar arm 115 on the front shaft 103.

Thusthe shafts 103 are given equal but opposite angular movements each time the boxes shift and the delivery in turn is synchronously shifted from one unit to the other. By reason of the slotted connections shown, the proper amount ofmotion for the fingers 104 can be derived from the box motion. Each unit or shuttle cell is seen, therefore, to have its own rock shaft 103 and selecting fingers.

Escapement devices are provided for each magazine to release the bottom shuttle and thereby permit selection by the fingers 104. These -escapement devices also act to prevent escape of more than one shuttle at a time from the selected unit. One such device is located at each end of each unit, and each escapement comprises a short vertical rock-shaft 116 journaled in bearing 117 on brackets 118 secured to an end frame 96. Each tle to support a whole stack of shuttles the short arm will swing out of the path of descending shuttles, as shown in magazine 90, Fig. 4, but when the shafts 116 rock, the lower arm moves to release the bottom shuttle as shown at magazine 91, same figure. The lowest shuttle is thereby released so that it will be free to drop from The short arms act to prevent descent of the shuttles above the bottom one which has thus been delivered. As the arms return to their normal position,- the shuttle resting on the upper arms drops to the lower arms ready for the next operation. These escapement devices, as stated, are located one at each end of each unit and the arms of any pair are operated simultaneously, hence the shuttles are owered in perfectly horizontal relation.

In order to transport a released shuttle to the previously described conveyor, I provide a carrier 121, see. Fig. 5, having at each end a supporting portion 122. Each of said portions slides freely in a slot or track 123, Figs. Zand 3 formed on each magazine end frame. The tracks areinclin ed downwardly and rearwardly so that the path of the carrier will intercept the arc of travel of the conveyor '77. By this arrangement there will be rapid divergence of the respective paths of the carrier and conveyor, permitting the latter to pass the carrier and assume a position nearer the front of the loom, from which position the conveyor moves rearwardly to takethe shuttle from the carrier. The carrier is common to all the magazines, the tracks being long enough to permit the necessary travel of the carrier.

.From the foregoing it will be seen that I have provided a multicolor magazine built up of a plurality of similar units each of which supplies a distinctive kind of shuttle. It will also be seen that each unit serves to space and brace the end plates of the magazine, and that the rear section of a forward unit serves as a guard for the .weft ends of the unit behind it. Furthermore,

the front sections of each unit are so formed as to define a slot which is in alignment with the delivery eyes of the shuttles, and these slots and the eyes are placed so that the shuttle can op erate in the normal manner found in non-automatic box looms, that is, with-the delivery eyes pointing toward the selvage when the shuttles are in the shifting shuttle boxes. Each unit carries its own selector, while the escapement devices therefore are carried by the magazine frames which are held in spaced relation by the units so that said escapement devices are properly related to the stored shuttles.

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 do not wish to be limited to the details herein disclosed, but what I claim is:

1. In a multicolor shuttle changing loom, a pair of spaced end magazine forming plates, and a plurality of similar reserve shuttle magazine cells located between said plates, each cell being formed of a single member extending between the plates and two other members spaced from each other to define a thread slot and fixed with respect to the single member.

2. In a multicolor magazine for shuttle changing looms, a pair of spaced magazine forming end frames, a plurality of shuttle storing units between the frames, each unit including a rear section section connected to and spacing both end plates, each unit including a pair of front sections having their adjacent ends spaced to'define a thread slot for the weft ends of the stored shuttles, and a thread holder in front of the forward unit, the

weft ends of the shuttles in any unit extending over the rear section of the unit in front thereof to the thread holder. v

4. In a reserve shuttle magazine for shuttle changing looms, a plurality of units each to contain a supply of reserve shuttles the thread delivery eyes of which point away from the selvage of the cloth being woven, a pair of. front sections for each unit spaced to define a thread slot which
