To all whom fit'fmaq/ concern:

Be it known that I, HOWARD a citizen .of the United States, residing lat Rockford, in the county of Winnebago and State of Illinois, have invented certain 'new andfuseful Improvements in Warp-Han' dling Apparatus, of which a specification.

the following is lThis invention relates to `apparatus for handling warps preparatory to the tying-in or twisting-in operation, andl .refers par# tieularly to a beam truck for serving .the

lwarp-tying machine shown and described chine. While the warptying machine is operating upon the war in one truck the" operator removes from tie other truck the tied-in Warp and puts in its place a new loom beam, arrangmg'the new warp in position to be placed in the .warp-tying machine as soon as the warpin the'other truck has been tied in.

which is secured a bed d. Clamps e and f for the new warp are supported above said bed, said clamps being provided with iiisertionbars g and 7L respectively. The old Warpv that is to be .tied tothe newwarp is supported in a` Warp-carriage c', said ca rriage ,being removable from the machine for convenience in securingl the old warp in said carriage and the new warp in clamps c and f. The 'warp carriage z' is supported abovethebed in any suitable manner 'and is provided with clampsyl and 7c, which clamps,.like those upon the bed d, are rprovided with insertion barsvZ and mv. The insertion bar of the clamp c is withdrawn, for convenience, by means of arms nl fixed upon a rock shaft 0 supported at the rear side of the bed Z and rotated by means of a crank -A12-.the upper end of eacliott1 the arms nv p. -is a spring clamp for receivingsaid insertion bar m. i y

I

As the beam trucks .a and o are identical, a description of one of themiwill suiiice.

The truck base in thisinstance comprises two end pieces 1 and 2 rigidly secured together by means of tubular longitudinal bars 3,4.and 5. A shaft G extends longitudinally ofthe frame a little rearward of .the bars i and 5, and is rotatably supported in suitable bearings in the end pieces l and 2. Atl opposite ends'of'the frame, bars 7 and S'extend upwardly, said bars being secured to the end pieces l and 2 at their lower ends and to A10 lying. within suitable'openings in said cap pieces and secured rigidly thereto extends across and constitutes the'upper'transverse` heads.

bar of the truck frame. Upon the inner side of-the bars 7 and 8 a piece of channel iron 11 is secured, the rear ends of said channel irons being supported by upwardlyoutside of the end piece 2 is rigidly fixed a rearwardly extending pedal 15, and tothe middle portion of said shaft is secured a forwardly extending pedal 16'. A coiled spring 1 7 attached at its opposite ends to the end piece 2 and the pedal 15 tends to rock the shaft 6 inthe direction to throw the dog 14 in engagement with the gear teeth e on the adjacent head of the loom beam t. The oscillatory movement of the shaft is limited by fingers 18 fixed by collars near the opposite ends of said shaft, said fingers engaging the tubular bar 4.

The beam truck is supported upon caster wheels 19 rotatably mounted in brackets 20, which brackets are secured at three corners of the truck frame. The brackets 2O are made adjustable in height by providing elongated openings 21 in said brackets, through which openings the attaching setscre'ws 22 extend. The remaining corner of the beam truck is supported by an arm 23 extending sidewise and slightly forward from one end of the truck, which arm has a pivotal connection with an upwardly extending stud 24 fixed in a bracket 25 secured to the floor near one end of the warp-tying machine. It will thus be seen that the truck moves in a curved path concentric with said stud 24, the caster wheels 19 running upon rails 26 secured to the Hoor.

The loom beam t. is supported in the truck upon two arms 27, the upper ends of said arms being forked to receive the ends of the shaft 'u of said beam. Each ofthe arms 27 is adjustably secured to the tubular bars 4 and 5 of the truck frame by means of a clamping screw 28 and a clamp block 29. The

position of the arms 27 may be changed, to

adapt them to support beams of various lengths, by loosening the clamping vscrews 28 and sliding said arms ,to the desired points upon the bars 4 and 5. While the truck is in reserve, the clamp containing the end of the new warp is supported upon the notchedy outer ends of the arms 30, said arms being slidably mounted upon the bar 10 of the truck frame, 'in order that their position maybe adjusted to correspond with the width of the warp being handled.

The means for securing the new warp in the clamp c of the warp-tying machine o will next be described.

A bracket 31 is rigidly secured `at each end of the truck frame upon the bars 7 and 8. Upon its inner side each of the brackets 31 is provided with a Iiange 32 and a rack 33. Upon a shaft 34 and near the ends thereof, are fixed pinions 35, each adapted to run upon the rack of one of the brackets 31. rlhe ends `of said shaft 34 lie in grooves 36 formed in the brackets 3'1. A tubular shaft 37 surrounds the shaft 34, said shafts being free torotate with relation to each other. Three arms 38 are fixed to' the tubular shaft 37 and support at their upper ends the insertion bar g for placing the new warp in the clamp cof the warp-tying machine. Said insertion bar is pivotally mounted upon the middle arm 38 (Fig. 8),

its ends being free to move slightly within housings 39 fixed to the upper ends of the outer arms 38. The arms 38 are held' in position to press the insertion bar g against the sheet of warp threads extending between the loom beam t and the clamp by means of crank arms 40 xed to the tubular shaft- 37, said arms being provided with studs 41 adapted to lie in openings 42 formed in hubs 43 xedito the brackets 31. Curved springs 44 fixed to said brackets releasably hold the studs 41 in their openings 42. Upon the rear side of each of the arms 38 is rigidly fixed-a linger 45 for a purpose to appear later herein. Being movably supported upon the brackets 31, the devices carrying the insertion bar g may be pushed rearwardly in the truck frame so to be out of the way when a loom beam is to be placed in said truck. The rear ends of the brackets 31 are curved downwardly and at the lower ends of the racks 33 are placed buiers 46 for cushioning the rearward movement of the insertioirbar supporting means.

-In mounting a warp upon the truck preparatory to placing itin the warp-tyingmachine, aloom beam t is placed upon the arms 27, and the warp ends, held in the clamp 03, are suspended from the arms 30 at the upper part of the truck. To obtain the necessary length of warp threads the beam is turned slightly, and to permit of lthis movement the dog 14 is withdrawn i from .its engagement with the gear teeth n of the loom beam by raising the foot lever 16 or by depressing the lever 15. When the warp ends have been t-hus suspended the tubular shaft 37 is grasped by the' operator and the insertion bar g supported upon the arms 38 of said shaft is brought forward. By reason of the racks 33 and the interconnected pinions 35 at opposite ends of the shaft 34, said shaft and the shaft 37 are always parallel with the axis of the warp beam.` Theinsrtion bar g when in its forward position bows the .sheet of warp threads outwardly," said bar being held in this for-- ward position by. the engagement of the I'.

studs 41 with the walls of the locking notches 42. As hereinbefore stated, the carriage t' for the'old warp is removable from the warp-tying machine for conveniencein placing the old warp in said carriage and the new warp in the clamps c and f of said machine. The new warp having` been placed upon the truck as just described and the warp carriage removed from the warptying machine, the new warp is secured in said machine by swinging the truck up to the machine, said truck moving in an arc described from the stud 24 as a center, and the insertion bar '(7 pushing the sheet of warp threads into the clamp e of the warptying machine. Aswillv be remembered, the insertion bar g is pivoted at its middle: so that in swinging forward it may enter said clamp squarely. ll'hen the beamtruck is in the position described, theclamp e is closed (by `means not herein shownf) 'to clamp the insertion bar g and the new Warp therein. The operator then takes the clamp .fr and lays thevsheet of new warp vthreads over the clamp f. 4The insertion bar L is `then pressed by hand into the clamp f and said clamp closed. The new warp 1s now in position to be operated upon. Then the old warp is removed from the loom to be tied to a new warp, the reed, vharnesses and drop wires are inv position upon saidv old warp. A piece of the cloth last woven is cut ott in front of the reed to prevent the threads from pulling through the reed, the opposite end ot' the 'warp being held in a suitable clamp (not shown herein). he old ,warp is secured mthe clamps y' and 7uy of the warp carriage t', and 4when the new :warp is-in place upon the warp-tying ma- .clnne the carriage 2,.w1t-h the oldfwarp clamped therein, is placed in position iii-the vwarp-tying machine. To relieve the warp carriage 'of the weight of the harnesses and drop wires, means aspro'vided upon the beam "truck, for` supporting said harnesses and ldrop wires, said means comprising arms 47 supported in brackets 48. Each of the arms 47 is longitudinally movable inits bracket 48, the longitudinal movement of the arm being limited by ay rivet 4-9 ixed in the bracket 4S and extendingthrough an elongated opening FIO-'insaid arm. To per mit of a vertical adjustment of the arms 47 the brackets 48 are provided with stems 5l lying within socketmembers 52 and clamped in any desired positionby means` of a clamp- 4ing screw A pin 5st extending through the stru ,its ends lying `in a vertical groove i in said socket member, prevents the bracket irom falling from said socket. The socket members are slidably mounted uponthe bar ofthe truck frame, whereby the arms e7 may 'be adjusted laterally, as well as vertically and forward and back.

59, being rigidly secured to the curved lower ends of said levers. The levers 59 are pivotally mounted upon studs 60 extending from slide bars Gl, said slide barsbeing slidably mounted within the channel irons l1. To exert a rearward pull upon the pin bar 5G l provide weights 62 connected to the studs G0 upon theslide bars 6l by mens of cords- G3, said cords running over sheaves G-fl rotatably supported in brackets' upon the rear ends ot' the channel irons'll. T he pin bar 56 is arranged to be held from movement by the weights G2, by means of a pawl 66 pivoted to each of the slide barsv 61, one end of said pawl being adapted to engage inclinedA locking teeth 67 upon .the channel iron 1l' and the vother end of 'said pawl lying in position to be engaged by' a pro- .je'ction G8 uponthe hand lever 5S). Then the hand lever is rocked rearwardly, the' projection G8 engages the forward end ot' the pawl 6G and raises the rear end ot said ,pawl out ot engagement with the locking teeth 67. To hold the pawl G6 in `such eleby the engagement of a stop pin 72 on the slide bar with thetail 73 of said dctent.

*The .pawl 66 is disengagedfrom the detent 69 by rocking the h and lever59 forward, the impingement of the lower end of said lever up'on the forwardV end of the pawl GG forcing vthe iear end of said pawl into the position shown in Fig. 4f, against the force exerted by the spring 70.

The operationof mounting a new warp upon the truck and of securing said warp in the clamps of the warp-tying machine has already been explained. The next step in. the operation of the apparatus herein described is to place the warp carriage i', with an old warp secu red thereto, in operative position in the warp-tying machine. The harnesses 1" are suspended from the arms 47, and. the warp-tying machine set in operation.. When the tying-in operation is completed the ends of the united warps .are held wit-hin the clamps e' and The warps are .then freed 'from said 'clamps by opening the To facilitate the handling of the united l clamps, and the insertionbarl is taken 'from the clamp 7' by rotatingl the insertioirbar remover-arms a upwardly to grasp said insertion bar, whereupon said bar is lowered onto the fingers ll5 at the rear sides of the arms 3S. The strip otl cloth attached to the old warp having been engaged with the pins 57 of the pin bar 56, the hand levers 59 are moved sharply rearward upon their pivots, the integral projections (S8 of said levers depressing the forward ends ot the pivoted pawls G6, and thus raising said pawls Yfrom enga gement with the locking teeth 6T. The pin bar 56 is thereby released to the action ot the weights Gir, which weights draw said bar rearwardly, its slide bars (Si being guided in the channel bars 11. The slack formed in the warps by the opening of the clamps c and y' is thus taken up and the warp drawninto a horizontal plane between the insertion bar g and the pin bar 5G, the transverse row of knots lying just in iront of the harnesses r. The action of the weights 62 in thus drawing the warp into a plane jerks the threads into substantial parallelism and helps to separate any knots that may have ber-omc tangled. The truck is now swun(r rearwardly into its reserve position, and the reserve truck containing another new warp is moved up to the tying-in machine. The new warp thus presented is clamped in the clamps c and f, an old Warp secured in the warp carriage i, said carriage put into its place in the warp-tying machine, and said machine again started in operation. When the machine has been started the operator is at liberty to draw the harness eyes and the reed over the knots in the warp just tied in (and which is held in the reserve beam truck.) 'hen this has been done, the arms 3S supporting the insertion bar g are pushed rearwardly in the truck, the ends of the warp secured in a suitable cla-mp, said clamp with the reed and the harnesses fastened to the beam in the usual manner, and the beam removed from the truck.- Another new warp may now be mounted upon the reserve truck in readiness to be tied in.

The foregoing detailed description has been given for the sake or clearness only, and is not intended as a definition or limitation ot the invention, the embodiment selected 'for illustration being susceptible of considerable modieation.
