The wire filling units for wire looms are prepared in one oftwoy forms, depending upon the character of the filling; in one forni, where a soft wire filling ora fine wire filling is employed, said llings are ordinarily prepared inthe form of a ball, and the filling is pulled out yfrom the inside of the ball; in the other form, or the form to which my invention is particularly addressed, where a large wire filling or a hard wire filling is employed, said fillings are prepared in the form of a spool,

loom of any preferred construction designed I for positively operating the shuttle by meansV of a bar, the general framework of the loom being omitted as well' as the parts of the loom other Jthan the bar anda portion of the lay, because such mechanismV and framework are well known.

In suoli looms, the lay ordinarily em-V ployed is composed of a horizontal beam, as 1, above the path of the shuttle, and a 'second horizontal beam, as 2, below the path of the shuttle, the two beams 1 and 2 being connected by two vertical bars, 011e of said bars 3 being shown in Fig. 8, the second bar would appear at the left but is not shown since the beams are broken away. 4 represents a casting formed with vtwo vertical.

slots 5, 5. In each slot is arranged a bolt 6. A nut 7 on each bolt serves to `clamp the casting 4 at any desired vertical adjustment on the beam 2, as well as to aline said casting. 8 represents an extension of the casting 4 formed with. two bearings 9, 10. Fach of these bearings 9 and 10 is made up of a horizontal wall or bearing 9a, as shown in Fig. 10, with respect to the bearing and a vertical wall 9b. 11 represents av cap plate, see Figs. 7, i8` and 12. 4As shown, this cap plate has the general shape of an angle iron, one wall of which, 11a, is vertical and the other wall, 11", is horizontal. As shown'in Fig. 10, the walls 9a and 9b of the bearing 9 engage the bottom and one side ofthe sliding shuttle bar 18` while the walls 11b and 11a of the plate 11 engage the top and opposite side of the shuttle bar 18, the four walls constituting a bearing in which the shuttle bar 18 slides.

Referring to Figs. 10 and 1,2,the wall 11b of the cap plate 11 is provided with holes 12, 12, 12, through which cap screws 13 pass and engage complemental screw-threaded holes in the vertical wall 9b of the bearing 9 to rigidly secure the cap plate` 11 in position. The wall 11b of the cap plate 11 is further formedwith two depending ears 14, 14, terminating in a boss 15, 15, that is finished onY its outer face, while the `complemental inner face of the ears 14, 14 are also finished. As shown, each boss 15 isformed witha slot 16.

Referring to Figs. 10 and 11,17 represents anadjusting screw arranged to enter complemental screwthreaded apertures 17 in the vertical wall 9F. This screw 17 at its outer end is formed with a head 17 b adapted to engage the iinished face of the boss lo'.

17c represents a flange fast on the screw 174 adapted to engage the inner or finished face of the depending ears 14, the latter occupying the space between the flange 17c and the head 17". By this construction the Wall 11L can be adjusted to the right in Fig. 10 to secure a proper fit with the shuttle bar 18, and also to allow for wear.

YReferring to Figs. 7 and 8, the left hand end of the shuttle bar 18 is formed with a mouth-piecevsocalled, 19, to receive one end of the shuttle 20. 4 21 represents a latch le-y ver in the form ofa bell-crank, pivoted at the end of one of its armsl22 by a screw 23 to the shuttle bar 18. The end of the other arm 24 is formed with a hook 25 adapted to engage a notch 26 in either end of the shuttle 20. 27 representsa rod one end of which is pivoted at 28 to the angle of the bell-crank latch lever 21. shuttle bar 18`in Figs. 7 and 8 is provided with a lug 29, formed with a perforation The right hand end of the 31 represents a coiled spring arranged on the rod 27 between the lug 29 and a collar 32,

secured to the rod 27 at any desired point by a set screw 33. The spring 31 when conipresseol tends to throw therod 27 to the left, in Figs. 7 and 8. 34 represents a pintle in the shuttle bar 18 upon `which is `arranged the forked end 35l of a rod 35, the opposite end of which is connectedto a suitable inechanism for givin to the shuttle bar its desired reciprocation. 36 represents an extension on the right hand endl of the shuttle bar 18, in Figs. 7 and 8. This extension carries a stud 37 upon which is arranged hub 38 of a bell-crank lever, the end of one arm of which is formed with a cam surface 39. The end of the other arm4 of this bellcrank lever is formed with forked arms 4U, 40, see Fig. 7 arranged uponeither side of a screw-threaded end 271 of the rod 27, vbetween two adjustable nuts 41, 41, see Fig. 17. The movement of the bell-crank on the stud 37 causes the forks 40, 40, by engaging the nuts 41, 41, to move the rod 27- to the right, Figs. 7 and 8, by means hereinafter described. The rod is thrown in the opposite direction by the action of the spring 31 when said rod is released from control of the forks 40, 40. 42 represents a casting, the lefthand end of which is formed with horizontal slots 43, 43. 44, 44 represent two bolts carried by the extension 8 and arranged in the slots 43, 43. Nuts 45,45 on these bolts serve to clamp the casting 42I to the extension 8 in any desired position of ad` justment to the right or left in Figs. 7 and 8.

. the opposite end of the shuttle.

amazes;

The right hand endl of the casting 42 is formed with an inclined cam surface 46, terminating in a horizontal dwell surface 47.l As the shuttle bar 18 is reciprocated by means of the rod 35 to the left in Fig. 8, the cam surface39 will engage the cam surface 46, drawing the rod 27 to the right in Figs. 7 and 8, pulling the hook 25 out of the notch 26 in the shuttle, and thus releasing the shuttle from this shuttle bar. As is usual in such looms, the shuttle bar continues to push the shuttle a short distance after the latch is released and while a corresponding liook ina corresponding shuttle bar on the opposite side of the shed engages During this continued motion ofthe shuttle bar shown, the hook is maintained out of engagement with the notch 26 of the shuttle by means of the cam surface 39 engaging the dwell surface 47. The latter surface controls the cam 39 long enough for the shuttle bar on the opposite side of the shed to engage and draw the shuttle-away from the i shuttle bar under, discussion. This is a point it-is seized by the opposite shuttle bar and pulled through the ybalance of the shed. The same description applies to subsequent passa es of the shuttle through the shed.

Re erring to Figs. 5 to 15, my improved shuttle consists of a lower plate48, the material of which at each end extends up to form a short vertical wall 49, then extends inwardly to form a rib50, thus providing a groove or raceway 51, 51, upon each side of the plate. Extending from each side of the plate 48 is a tang or shuttle nose 52, 52, f

each of which is formed with a notch 26.

The top wall of the tangs 52,52is extended over. the plate 48 asa bridgepiecel 53 con,- necting thetwotangs. The main'palt of the bridge piece 53 is slightly above the top surface of the tangs 52, see Fig. 15, being formed with an incline 54 at either end.

55, 55 represent slots in the inner 'end of the tangs 52, said slots opening into the chamber formed by the plate 48 and the` bridge piece 53, and extending across atf 55L the ribs 50, 50. 56, 56 represent latches arranged in the slots 55, 55, and mounted on the pintles 57, 57. One end ofthe latch,

as at 58, can project into the chamber through the space 55a inthe rib. The op-` posite end of the latch is formed with a r 58 of the latch into the chamber, into the space 55a, across the groove 51. Theinner end of eachslot 55, 55, is formed by an inner wall 63, 63, which engages the arm 58V of the latches56, 56, and limits the inward movement of the end 58, 58, of the latches. The shuttle thus far described differs from prior shuttles used in wire looms, so far as l'. am aware, in the provision of the latches 56, the plate 48 rigidly secured to or integral with the shuttle body, the ribs 50 and the grooves 51. The tangs 52 with their notches 26 are common to shuttles used in wire looms'. v Referring to Figs. 5, 6, 13 and 14, wherei is shown my improved filling unit adapted to handle klarge wire fillings or hard wire fillings, 64 represents a plate formedwith side flanges 65, 65, adapted to lit and slide in the grooves 51, 51 of the shuttle. On its upper surface and inside the flanges 65 this plate is cut away to form an inclosed circular space, as 67, having a bounding wall 66.

In the center of the circular space 67 is an opening 68 formed in the plate 64 to receive the end of a post 69 that is rigidly secured to the plate by upsetting or otherwise.

apiece of metal to the form shown. 7 0, see Fig. 13, represents a circular plate formed with a .central opening`71 adapted to fit loosely on the-,post 69, permitting the plate to reston the bottom wall of the circular opening 67, the said platebeing of less diameter than the circular opening 67 72 represents a vertical circular extension of the plate 70,:but offless exterior diameter than the plate 70. This construction may be `cast or turned up` or ymay be made of two plates secured together, eachliaving a uniform opening to take over the post '69,' but the plate 70 being greater 1n outside diameter than its vertical extension 72. 3, 73 represent two `pins secured inthe plate 72 and adapted to enter corresponding holes 74, 74, in thespool hereinafter described, see Fig'. 9. 75, see Figs. 5 and 6represents a coiled spring arranged in the circular chamber 67. The inner end of this spring is loosely positioned in a notch 76 of the 4The plate 64 as described may bek either cast or it may be turned down from' ico i plate 70. The outer end of said spring 77 rests against the inner face of the wall 66, but is notv attached to it, so the springv can drag along the surface of the wall of said rib. In-assembling this part of 'the `filling unit the plate 70 and its extension 72 are Q dropped over the post 69 and the spring 7 5 arranged between Vthe plate 65 and thewall 66 withy thej inner end 78 of the spring arranged in the notch 76. Then la circular plate ,7 9 formed with an opening sufficient to slide. down over the edge of the extension 72 is slid in lace, resting uponV the wall 66 and extending over the upper. wall 80 of the plate 70, but notI engaging the cirshuttle will be substantially'the same.

-. 83, having a right angle wall 84 on one side and an inclined wall 85 `on the other. .The flanges 65beyond the notches 83 are beveled, as at 86, 86. The plate 64 at its opposite end is formed with a notch 87. The bevels j86, 86, are `to facilitate the introductionof this plate and the parts carried thereby into the shuttle. Said inclines further serve to engage supplemental inclines 86a, 86CL on the latches to push the latter one side until they come opposite the notches 83 when they are snapped` into place in said notches by the action of the springs 60,60. The notch 87 is designed to engage the filling outside of the shuttle to keep the filling in place when several of these fillingy `units are stacked in a magazine. This notch has no function after the unit has been placed in the shuttle.

Referring to Fig. 9, my fillingholder or spool consists of a barrel, as 88, formedwith a central opening, as 89, to loosely fit on the post 69. 90, represent two plates of hard steel, one arranged" upon either end of the barrel 88 and secured thereto by .rivets 91. The plates 90, 90 are circular and formed` with openings corresponding to openings 89. These plates form the side walls of the.

spool, the lling 92 being wound upon the barrel 88 between the plates 90, 90. The barrel is preferably made of wood or some light material, with holes 74, 74 to receive the pins 73, 73. The spool constructed as stated with its filling is slid'down upon Vthe post 69, the pins 73 entering the holes 74. With the parts arranged as described, vthe spring 7 5 acts as a friction to yieldingly resist the unwinding motion of the spool.

When the filling in a shuttle has been exhausted from a spool at a predetermined point,another filling unit such as shown in Fig. 5 is inserted in the shuttle, pushing out the prior filling unit and at the same time the plate of the new filling unit is locked in place by the latches. rllhis can bedone by hand, but preferably automatically, as set forth in another application filed by me.

vIn Figli, the commencement of such substi# tutionlof a full unit for an exhausted unit is' in part illustrated. Prior to my invention, so far as l ain aware, the substitution of `filling units in the shuttle of a wire loom has been done by hand. lllhether such substitution be done by hand or automatically by using my improved filling unit, the action of the latter in its entry to and exit from the either case the shape and arrangement ofthe walls 84 land 85 of the notches 83, combined with the shapeof the operative face of the latches 56 carried by the shuttle is such 'that InV these latches are pushed bach o'utoffengagcment with the notch by a continued movement of the .plate in one direction, but said i hold the plate againstreverse imo latches tion.

4Referring to Figs. 7 sents a block formed with holes ateache'nd 21h. This block is arranged 'in the hollow shuttle bar 18 and secured-inplace by rivets 2lc passing through the wall ofv the shut l '7b sidev is formed witha` recess 21min which-isy tle bar and the holes 21". Thisiblocklon-one arranged the arm 22 of the latch21 and pivL otally mounted as heretofore described upon the screw 23.
