Original application led April 2, 1923, Serial No.

' 1924; 'sefia1No.724,597.

This invention 'relates to looms and in particular to sof-called box-looms, `that is, looms inv which a plurality of shuttlesv are used and they are vselectively brought to position vfor flight across the lay by shifting a container or'boxv structure therefor into proper relation tothe lay or hatten for such flight of the selected shuttle. In the present adaptation of the improved box-loom two shuttles are employed and they are'de signed tobe calledV alternately at regular intervals; in short, the loom is of the twoby-one type, i. e., wherein there is asingle or fixed box at one endof theflay Vand/a f shifting box structure'having two cells for the two shuttles Vat the other end.` These detailshowever, are to be regarded asl immaterial. `'The present application is rnyuapplication, Serial No. April'Q, 1923.V

The improvements contemplate movement Vof the boxes transversely of thebatten and a division of 629,274, ned

means for effecting release of" each shuttle when it is vabout to be thrown across the batten or lay. Y

In the drawings- Fig. 1 is a 'side elevation of a loom embodying the invention; l Y Fig, 2 is a plan of the shuttle-boxes5 Fig. 3 is a front elevation thereof; and Fig. Ziis a4 sectional view on line lL- 4, Fig,`2, one check-lever having been moved to releasing position.

The loom shown i Fig. 1- is the type 'set `forth for example, in my application YSerial No, 615,988, Patent Nol1,564,386, in which each picking member 1 is impelled so as to throw the shuttle by first cooking it subject to thetension of a spring, as 2, and then releasing it,-as through the medium of a lever 3 for effecting the cooking which 'is oscillated from a rotary means 4 in gear with the crank-shaft 5 of the loom which, through pitman 6, reciprocates the batten 7 anda lever 8 for effecting the release, also I oscillated from means 4. This, however, is

immaterial in reference to the present invention. y y

` The battens 7 has the picking member 1 movable in a slot 9 (Fig. 4) therein in the way usual in plain looms. That is to say in stead of thewooden beam forming the batten terminating in substantial coincidence 629,274..v nividea and this appueationniea July 7,

with one side ofthe loom and being equipped with an extension frame in which the box-structure is to slide, according to the usual construction of box looms, 'it is left extending and provided with the' slotV 9 for the picking member, asin plain looms. 11 (Fig. 3) is the shuttle race-board, which in the present case 'is made' totermina-te near the `side frame loflthe loom.

A plate 13 (Fig. 3)v is fixed on -the projecting end of the battenfand forms'the bed on which the boxestructure is to slide.

Near its inner end it has atransverse groove 111 formed in its top surface; it'sjouter end portion is thickened up and has an overhang 15. The plate yalso has a'slot 1G which registers withthe vslot 9of the hatten. At its inner end and at front and back it has the upstanding ears 18. At the back two bearing arms 19 project from the plate,`the purpose of which will be explained hereinafter. f

n this plate slides transversely ofV the batteri "andr horizontally a box structure which mayvbe'described asffollowsIt has a, longitudinal central cross-sectionally I- shaped partition V2O whose basal portion 21 forms with the strips 22 the floors of two shuttle boxes, one on each side ofthe partition, Veach slot left at23 being adapted to register with the "slot 16 whenthe box structure is shifted.l YIt has an underneath guiding rib'27 torun in groove 14:, and to retain it in place thereisa fin 28 engaged under f overhang 15 and a plate29 bridges the upstanding ears v18.V There isv a transverse housing30 at the outer end of partition 2O and fixed thereto, being divided by the partition. It 'will be 'understood that aV shuttle s'paceis formed at each side of the partition. On vertical studs 31 in the housing are fulcrumed the outer ends of stiff inflexible check levers 32,ea'ch of which is held by a plate spring 33 pressed inwardly against a thin steel strip 34 forming the outer wall of the box (the inner groovedwall of which ico is formed by the partition 20); eachplate spring is supported at loneend by the end of housing 30 andby a pin 35 at the other. The spring, acting through the lever, normally exerts pressureY on the strip 34: which coacts normally with .the partition `to grip v a shuttle if present in the' box.

,as in my mentioned appleaten Serial VNo. 615,983, the pressure exerted on each shuttle when entering a box is relieved at the moment it is imp elled. effecting `this includes a pair of bellcrank levers 36 which are ulcrumed on pms 37 on the shuttle box structure so that the horizontal arm of each projects toward the other lever and the other arm projects down relatively inward of the free end of .the check 1the shuttle then alined with the hatten is to be shot Jfrom its box the lever 38 is caused Vto depress the lever '36'it thenroverlies to porting lstructure having a shuttle race, a

, move'outward the corresponding check lever 44'onn thebox structure by links 45.

and so relieve the pressure on the shuttle.

VThis may be accomplished by the push-rod 39 moving vertically kin suitable guiding means 40 on the lay-swords supporting the bat-ten and actuated ingany Way (as by lever 8)'on every other pick of the loom;

A picker 12L slides on bed-plate 13 over slot V16, being penetrated by the stick l in the'usual Way. .t thev outer end of lthe bed-plate is a suitable housing'41 for the picker. f

- In the arms 19 is ulcrumed a rock-shaft y 42 carrying levers 43 connectedWith ears A lever 46 on shaft 42 is connected by an adjustable pitman 47 With a lever 48 fulcrumed in the side of the loomy frame. By a suitable oon nection 49 .thislever'is connected With any suitable dwell-motion mechanism 50 driven by gear' 4. Y Y

Having thus fully described my invention, what I claim as new" and desire to secure'by Letters Patent is c l l.l In combination, a hatten-including supporting structure havinga shuttle race, Va

setr of shuttle boxes movable transversely of the race and having means acting to hold each boxedrshuttle in its box, means to move the set offrboxes'to place one and Vthen-anoth- The means for er box in alinement With the race, means to eject from the box so alined with the race the shuttle present therein, and means to move the first-named means into releasing relation to *suchv shuttle prior to such ejection thereof from the box.

2. In combination, a hatten-including supporting structure having ashuttle, race, a sei'I of shuttle boxes movable transversely of the race, separate means, one for each box, acting to hold the shuttle 'boxed therein, means to move the set of boxes to place one and then another box in alinement with the race, means to eject from the'box so alined With the race the shuttle present therein, and means tocause the corresponding one of the lirst-named means to release such shuttle prior to such ejection thereof from the box. Y y 1 3. In combination, a hatten-including supset otshuttle boxes movable transversely of the race and having means actingv to hold each boxed shuttle in its box, devices, one for each box, to' cause said means to release the shuttles, means to move the set of boxes to place one and then another box in aline-` for and movable transversely With each box,

to cause said meansto release thje shuttles,

means to .move the set of boxes to place one and then another box in alinement with the race, and means, on each such movement and With reference tok whichV said devices are movable With the boxes," to cause the device kcorresponding to the shuttle so alined with the race to cause the first-named means to release such shuttle-` In testimony whereof I affix my signature VVILLIAM S.
