SHUTTLE-ACTION Fonl Looms.
To all whom t may concern: l
:Be 1t known that we, 'JOZEF yVVoJTI'AsI'E- wrczandJoHN ZAJAC., citizens of Austria,
residing at ,Chadwicks in the county of Oneida fand State of yNew York,.ha\`fe vinvented Certain new andusefulImprovements .in Shuttle-Actions -for Looms, ofv which the `following is a specication,jreference being yhad therein to the accompanying drawing.
Our inventionrelatesfto a shuttle. action for looms and we declare the lfollowingto be .a full, clear, f concise and Iexact description .thereof sufficient to enable kanyone skilled .in theart to which it appertainsto .make vand use the same referencebeinghad Vtov-the accompanayingdrawings in which likereference characters refer to, like parts` throughlout the vspeciiication.
The object oftheeinvention is to provide a durable device for throwing` theshuttle .across the loom in the usual manner of A weaving. 'Inthe construction of looms, heretofore, the mechanism for throwing the .shuttle across the loo-rn was under so'. great a strain thatfrthe parts in lconnection therewith .wore out 4very A quickly, .i thereby necessitatingvnew ones. y'This invention is designed to overcome that serious defect by .transferring .the strain to levers o that l are moved alternately, whereby to `eilect. the .lac-
tuation of the shuttle. y
The object will- Albe understood by reierring to the drawings in which:
Figure 1 is a perspective view of .the

l V.The end'ofthemember. 15 opposite the end l-is'redu'ced at 23 to allow for the vertical. movement `of the Lshuttle boxes24 holdwhich carries adifthey do notmove horizontally; Each of the 4boxes 24is formed' with a slot 45fin one side, through which proj ects: the picker endY 46 of -an 'arm A47 that Ais adapted to move forward to throw the shuttle 20 across the loom in the well'knownfmanner.
The opposite end of the armv 47 lis sleeved at 49 tofride along the guiderod 50 having bearings atone end in thesword 4 and at the other in the plate 51 -attachedlby a bolt'to the member'l. A
`Each of the boxes 24 hasan openingat 48 adj acentthe rear end, `whereby.thepicker 46 of the arm 47 lmay pass fromthe slot 45 of "-the one box 24 to theother, when said boxesy 1 24-are shifted in a vertical manner.
" The'arm `47Yis provided witha reces'sfup f through which projects a vpost*v 54 `fixed to themovable slide 55. lA cleat 56 having `anelongated slot 57 is attached to the side of ythe member 15 and is secured at one end to the plate51 and at the-other to the enlarged part' 58 of the sword 4. The slot 57 is formedfor the horizontal movementof the post 54.V The movable slide is shouldered v and fits into a Vcorrespondingly formedrecess v'in the lower portion of the member 15 and fof the cleat 56,-similar tothe construction'pf the end `16 of the member V15. The slidef55 has a bolt 60 to which boltis attached a cordV 28a to connect said slide v551to a lever 29a fulcrumed to a bracket 31a mounted to across bar 32a of the frame 1 -f. Y The cord' 28a passes over thegrooved guide pulleys 61, `62
yand'irv adapted to revolve upon the axles .-having bearings lin the brackets 64, 65 and 66, respectively.V yThe bracketV 64 is fixed to,
the member 15 of the andthe brackets with' a nub 40a againstv which impinges a roller 41a that revolves on an axle carried by an arm` 42a. The armv 42a Vis fixed to turn Y withthe rock` shaft 13; On each revolution its fulcrum and Yagainst the tension of the; coiled'spring 43 thatV is disposed between 'the u lower surface ofthejlev'er 29 and the upper L ofthe arm "42a, the roller 41a impinges against the nub`4()a tomove thelever 29a' againstthe tension ofa spring 43,t` whereby to exert apull on-,the cord 28 to actuate the arm 47 and the shuttle 20 vacrossthe loom in the well known-.mannen.v
Y' lnbperation, thel crank shaft 7 i reckshaft 13 are revolved by means ofthe meshinggears 11 and-#12rand-theV pulley-14 which is turnedV by any well known motive power, not shown here.
The. crank: shaft 7 will revolve faster than the shaftlfbecausefof thefratio ofv gear 1 1 to gear 12, gear l11 being smaller than-gearV 12. As
the crank shaft 7 revolves, the lay v2 which is-connected thereto by thek arms 1 0 will rock back and forth.` Furthermore, .there-VV volving of -Ith'e shaf-tlSf-will. cause the 'rollers 41`- and-41a-on the arms 42 andr42to Valternately. strike `the nubs-40 'andf'f402L of the nlevers r'j29--and 29a and thereby depress said levers'29 and 29a against the tension-of the springs 43 and 43a, wherebyfto'elfect a pull 1in each instanceupon the respective cords 28 Ysupply the woof thread to the fabric.'v The shuttle boxes 24 will be shifted vertically at the proper times to furnish a diiferent'shuttle 20V carrying a given coloredthread,`
