((11. ‘139-232) This invention relates ,to improvements in looms and it is the general object of the inven~ tion to provide a loom which 'may be readily convertible from an automatic weft replenish-I 5 ing loom operating with a plurality of weaving shuttles to a loom opera-ting pick and pick with drop boxes on both ends and capable of accom modating a‘ larger number of shuttles. The class of goods which a textile mill is called if) upon to manufacturemay vary considerablyv as to the variety of weft, the simpler fabrics calling for a comparatively small number of shuttles, in which case it is expedient to operate the loom automatically, and the fancier fabrics calling for atlarger number of shuttles which cannot con tion resides in the combination and arrangement of parts hereinafter described and set forth. I In the accompanying drawings, wherein a con venient embodiment of my invention is set forth, Fig. 1 is a front elevation of a loom having my invention applied thereto, the magazine being shown operative to effect automatic weft replen 1O ‘ Fig. 2 is a View of the right end of the struc— ture shown in Fig. 1 but with the magazine swung to idle position to accommodate a gang of shift~ ing boxes similar to the set on the opposite end, Fig. Bis an end elevation looking in the direc~ 15 ishment, veniently be replenished automatically by simple tion of arrow 3,‘Fig. 1, the lay end and shuttle‘ mechanism. box being in section, It has been necessary heretofore to maintaina section of automatic looms to weave the simpler fabrics and maintain a second sec tion of. looms having drop boxes on both ends, to weave the fancier fabrics. It is an important object of my present invention to provide a loom having the automatic weaving instrumentalities in place when weaving simple box patterns, but capable of being swung to inactive position on the loom to permit the addition of drop boxes at the magazine end of the loom. The magazine is mounted so that it can be thrown up to a position where it will not interfere with the shift , V Fig. 1i is a perspective view of the magazine end of the lay adapted for weaving pick and pick, the magazine being shown in non-operative position, Fig. 5 is a view looking in the direction of arrow 5, Fig. 2, indicating in full lines the arrangement for automaticandin dotted lines for pick and pick I weaving, Fig. 6 is a detailed vertical section on line 6-6 of Fig. 1, and ' l - Fig. '7 is a detail plan in the direction of arrow 7, Fig. 5. beam,‘ and furthermore,‘ there is usually a brace Referring to the drawings, I have shown a loom which is adapted for weaving either 4x1 or 4x4, that is, four boxes at one end and one at the other, or four boxes at each end, although the in vention is not limited to the speci?c number of between the top of the magazine and the loom arches to prevent undue vibration. It is a fur ther object of my present invention to modify shuttle boxes set forth herein. The magazine is 35 of the customary multicolor type and follows a construction which has gone into general use, be the top brace so that it ‘can be used as a pivot about which the magazine can be swung to in ing arranged to store four distinctive types of re 3 O ' ing of the shuttle boxes adjacent thereto. The magazines of weftreplenishing looms ordie 'narily include in their construction a foot to be bolted or otherwise secured to the loom breast vA10 active position when the loom is converted from automatic to non-automatic pick and pick. ' 'When the loom is weaving automatically the magazine is ‘generally located with a portion thereof nearer the center of the loom. than the adjacent ends of the arches. It is another object of my invention to provide a brace preferably so constructed as to permit an endwise sliding of the magazine away from the center of the loom so that'the arches will not interfere with the magazine as the latter is ‘pivoted to idle position. A still further object of the invention relates to connections between the brace and the magazine ‘ With. these and other objects in view which will appear as the description proceeds, my inven serve weft bobbins which are drawn when needed. for insertion into a selected depleted shuttle.

The left end of the lay is provided permanently with a set of shifting shuttle boxes it having a plurality of cells, four in number in the present instance, and indicated at l6, ll, l8 and it, re. spectively. vThese shuttle boxes may be posi tioned with respect to the shuttle race 20 of the lay by vmeans of a box lifter rod 2! moved ver tically by a chain 22 the position of which is determined by a pattern mechanism such as a which permit the latter to be adjusted both ver tically and horizontally with respect to the trans Knowles head, not shown but well understood.

The left end of the loom may be of usual construction and of itself forms no part of my present invention. The right end of the loom is modi?ed so that it can accommodate either a single shuttle box, or thereof which as shown in Fig. 5 is positioned to engage the foot 45 of the magazine and prevent forward motion thereof to the left toward the lay from the dotted line position shown in Fig. 5. u four shifting‘ boxes,_as desired.

A similar of the tie rods 42 by means of set screws 6!, see plate 89 having a groove 90 may be located per manently to the lay at the inner end of the gang Fig. 5.

When the 100m is to be reconverted for auto matic weaving the rod 95 together with the gang 80 of shuttle cells, is lifted upwardly out of the loom, the chain 98, however, remaining attached to the sleeve 96 and the rod 99 together with the spring I02 acting in normal manner. The rela tion of parts is such that even should the chain 98 move in response to pattern chain indica tions there will be no resultant interference be cause the chain and the parts operated thereby lie behind the spent bobbin can I 05, shown in' Fig. 3, and are below the bobbin chute £06 down which the expelled bobbins move from the slot 35 to the can I85. In this way a considerable part of the mechanism which operates the gang of boxes 89 can be left on the loom when the latter is operating automatically. 40 From the foregoing it will be seen that I have provided simple means whereby a loom may be used either to operate automatically with a maga zine to supply reserve bobbins, or non-automati cally to weave a more elaborate pattern calling for magazine in transferring relation with respect to the lay when the latter is in foremost posi tion, and additional support means behind the pivotal support positioned to cooperate with the pivotal supportto hold the magazine in a non transferring position with all parts of said maga zinebehind the lay when the latter is in rear most position. .

It seen that the plate 85 is readily removable when the loom is converted from pick and pick to auto matic, thereby avoiding interference with the rear part of the magazine as the lay beats for wardly. Again, it will be seen that the removal of the gang 88 together with its rod 95 per mits the retention of the chain 98 and sleeve 96 which are located behind the bobbin can H15, in which position movement of the chain 98 will cause no damage. ,Also', the support 15 is so 60 constructed that the hooked ends 16 thereof so with respect to the loom to support the magazine in a non-transferring position, said additional, support assisting in maintaining the magazine behind and clear of the lay when the latter is rearmost and when the shifting shuttle boxes are in their highest position with respect to the 55 lay. 5.
