To all @nimm z't may concern Be it known that l, WILLIAM S. WELLS,

a citizen of the United States, resid-ing at- South Bethlehem, in the county of Lehigh and State of Pennsylvania, have invented vcertain. new and useful Improvements lin Looms, of which the following is 4a specilication.

rlhis invention relates to looms, and it cons-ists in certain improvements vdesigned especially for the weaving of more or less tightly woven and heavy material,z-such as bel'ting, where the shuttle vor equivalent is best carried, and not merely thrown, through the shed 'and the :beating-up 1action best involves quite Ia sharp blow to'lay the filling properly up to the )fell of the clot-h. Besides including novel means, :answering these requirements, for passing -the filling into the shed and Athen beating it up, my invention comprehend-s lcertain other .novel features, among which may 'be mentioned .a iilling replenishing means and a :harness motion. f

The lines A-., iB-,C-A-,in lFigs .Land 2 fdenote the elevations assumed fby the points Zfand Z at ethe highest, lowest .and either midway positions of the wrist pins j j', respectively, in one cycle of rotation. The point Z (or Z) obviously performs its downward-and-back movement, between C and D, faster-l than it does its upwardand back movement, between y-C and A, thei'flrst or downward half of the former movement.

being further an appreciably accelerating one-up to a point near'the limit of such movement. The means described are therefore well adapted to produce, in effectalai.

roller m is j ournaled at the front of the side standards a a and a guide roller n' is journaled above it; Abracket 0 is fulcrumed in said side standards between the rollers m and n, and in it are journaled the rollers p, Q, the latter of which bears on the former; a spring 7' normally presses the bracket upwardly. The cloth extends over roller n, around the sand roller m, and then between rollers p and q; in coaction with the let-olf mechanism, thesand roller preserves the desired tension, roller g, by being held by spring r pressing yieldingly against the cloth between m and n, permitting-the giveand-take incident to the opening and closing of the shed. The sand roller shafts carries at Vone end a worm wheel t which engages with a worm wheel u on ashaft o, journaled in the frame', which carries a ratchet wheel w' and on which is fulcrumed a lever m connected with lever le by a link y and equipped with a pick awl z engaging the ratchet wheel.

` 2 is the warp beam and 3 the whip roll journaled at the back of the loom, the warp beam being provided with some suitable rotation resisting medium, preferably a strap f1 which engages its periphery and has the end thereof corresponding to the.

direction in which the beam rotates connected to thev frame by the spring 5 and the other lend wound around and suitably secured to the pulley 6 having a weighted arm 7 Y yBeating-uy? merma-The lay or hatten struct-ure, as herein shown, includes a singlelay-sword 8 fulcrumed on a cross shaft 9 connecting the standards a.. Its head or lay proper has the reed 10 suitably secured thereto, as by bolts or screws 11 (Fig. 2). The lay-sword is connected with a'lever 12 by the pitman 13,` said lever beingY fulcrulned on a cross-shaft 14, connecting the side frames a, and being connected with the stud Z by the link'l; adjustment. of the throw of the lay-sword may be effected by shifting the connections between 12 and held depressed by a spring 23, and these levers are respectively connected with the harness frames 18 by the pitmen 251-24. To obtain the alternate rise of the harness frames I employ the following mechanism:

' Suspended by a universal joint 25 from the lever /c is a lifting hook 26 arranged between the levers 21-21 andY having a hook or stirrup 27 on each side thereof so that it is adapted to lift either lever on being swung sidewise. The lifting hook is normally pressed to the left by a spring 27 attached to a horizontal plate 28 in an opening in which the lifting hook plays sidewise (Figs. 2, 3 and l), and may be pulled to the right by a cam 29 on the cam shaft against which bears a lever 30, suitably fulcrumed in' the frame and connected with a bellcrank lever 31 by the pitman 32, the bellcrank lever being connected with the lifting hook by the spiral spring 33. The shafts (l and rotating at a speed ratio of 2 to l,

'it will be seen that upon every other lifting movement of the lifting hook (there being vone such movement following each beatingup movement of the lay) the lifting hook will be shifted by spring 27 into position to lift the left-hand jack 21 and upon the remaining movements will be shifted from (ram 29 into position to lift the right-hand jack 21. Thus the harnesses rise and fall alternately, the weave produced in the present case being a plain tabby.

Shuttles-The type of shuttle used includes a cylindrical shell 34, closed at both ends exceptas hereinafter noted, having approximately half of Yits cylindrical wall vforming -a hinged cover and having a bow 35 on the other half provided with superposed eyelets 3G; projecting inwardly from one Side of the 'bow is a novel tension device in the form `of a helical spring 37 fitted at one end over a stud 33 on the bow and having at its free end a guilding eyelet 39. The thread extends from the filling package through one eyeletl 36 then through the eyelet 39 and then through the other eyelet 36, the spring 37 obviously yielding to preserve the tension uniform. Adjoining the bow the shell 3l has an opening 34 through which the thread extends. At its right-hand end the shell has a headed stud 3S, its head being formed conical or rounded; at 'the `other end the shell has 'a hole y38. The. core of the filling package is a tube 41 longitudinally slotted andk containing athrustpin or detector 42 which a spiral spring 43, also contained in the tube, tends to cause to protrude from a suitable hole 43 in. the left-hand endv of the tube and (when the tube is housed in the shell, with its ends resting in sockets 44 provided therefor therein) from'the hole 38 of the shell. The detector has a beveled iin 45 protruding from the slot of thetube. When the tu'beis wou-nd with filling' the detector is held retracted (Fig. 17) thereby, it being allowed to protrude fr0-m the shell only when the filling has been so far used up that it no longer can resist the pressure of the spring 43.

Picking motion and ZZz'f/ig replenishzng-f-At the left ofthe loom, opposite the front standard is a magazine consisting of two uprights 46 `upstanding` .from a bracket 47 bolted to the frame, the same having vertical ways 48 in their adjoining faces and the front one having slits 49 (Fig. 11) entering to its way. The magazine is open at the top and bottom, and into i-t from the top is adapted to be entered a stack of receivers .each carrying a shuttle and constructed as follows: The base of each receiver is a flat rectangular block 50 which engages at its vertical edges in the ways 48, preferably having itsl two forward corners beveled, as shown in Fig. 11. Projecting from the inner face of the block is a socket 511 of a diameter to reecive, more or less snugly, the left-hand end of a shuttle. The socketr has a spring-pressed shoe 52 to bear against said end of the shuttle and holdA the latter by slip-.friction therein. lThe block has a hole- 53 through which the shuttle detector 42 may protrude.

The shuttle-carrier comprises a horizontal y transverse rod 54 adapted to reciprocate in brackets 55 on the front standard b and a cylindrical socket. 56 secured to the lefthand end yof said rodland slotted at the front to accommodate the bow of the Shuttle. The right-hand end of the rod is suitably connected to the picking stick 57 which is connected with stud Z by the link l58. There is always one receiver (the Vlowest in the stack) directly opposite the shuttlecarrier. Fullcrumed in the socket 56 and in anY arm 59 carried by the rod 54 (Figs. 7 to 10) is a locking rod 60, the end of which Awithin the socket forms a crank 61 to-interlock with the head of stud 38 on the shuttle; the locking rod also carries a forked crank 62 which embraces rod 54 (so that Ithe rocking movement of the locking rod is limited) and which is connected b-y the spring 63 .with arm 59 so that crank 61 is normally held in position to interlock Vwith stud 38. Back of the shuttle carrier there is fulcrumed on front standard ak cam-shoe 64 ing of the shed the shuttle-carrier performs a thrust to the left and (locking-rod 60 being then uninflu-enced by the shoe) receives the waiting shuttle in itsI socket and, the interlock or coupling being effected by crank 61 ridingy over the conical end of the stud 38 and engaging back of it, carries it Y to the right. Beating up again occurring upon the shuttle having cleared the shed at the right, on the next opening of the shed the shuttle-carrier performs another thrust to the left and back, at its left-hand limit leaving the shuttle deposited in the receiver due to shoe 64 this time rocking the lockingrod and holding it so that its crank 61'can` not interlock with the shuttle stud. n other words, on itsv alternate thrusts the .shuttlecarrier picks up and carries, the shuttleto the right andfback, and on the remaining thrusts leaves it deposited in the' receiver.

The stack of receivers isl supported by one or the other of a pair of thrust checksf?Y 1 sliding in the slits 49 ofthe magazine and pivoted at the oppositel ends of arocker 72 which is fulcrumedin a bracket 73 project.- i

ing from the magazine (Fig 3) andv has a ynotched arm 74; a spring 75 coiled about the upper check between a collar thereon and the magazine holds the partis 71 7 2 normally in the position shown in Figi 11, where the lower check protrudes into the magazine and supports the receiver-stack. 1f the arm 74 be depressed 'the' 'withdrawal of the lower and introduction'Y of theupper check will obviously result in the lowest receiver beingV allowed to fall Vfromjthe magazine (76, Fig. 2, being adho'ppe'r to re? ceive it) while the remainder of the stack stands supported by the; upper check; on the return movement of the rocker, the remainder of the stack will fall into engagement withand be supported by the lower check. The first of these movements of the rocker is effected by a hook 77 having a universal connection 78 with a crank 79 on a rock-shaft 80 journaled in suitable bearings at the left ofthe frame, said hook being normally pressed back, so as not to catch the arm, 'by a light spring 81. The

rock-shaft has a crank'82, which, Vby alink 83, is connected with a lever 84 engaging a cam 85 on shaft f. The hook moves down and back on every other pick of the loom (t. e., when the shuttle remains in its receiver) and so long as the filling lasts 1t descends without actuating the checks, thus: A two-armed lever 86-87, the arms of which are yieldingly connected by the spring 88 so that one can swing without movement of the other, is fulcrumed on the stud 89 projecting laterally from the magazine (see F ig. et). The inner arm 86 of this lever plays across the hole 53 of the lowest receiver (Fig. 11) and if the detector of the corresponding shuttle projects from said hole said arm will be prevented thereby from descending with the other arm. There is a bend forming a cam-face 90 in the hook so situated that if the hook descends while the arm 86 is thus prevented from descending the hook will be cammed over, and so carry down with it, the arm 74 of the rocker, but will remain clear of said arm 8G if the latter also descends. The lever 86--87 is rocked down and back substantially in consonance with the down and up movements of the hook through a link 91 connecting its arm 87 with a crank 92 on a sleeve 93 arranged on the rock-shaft 80, said sleeve carrying a crank 94 which is connected by a link 95 with a lever 9G engaging a cam 97 on shaft f. (Levers 8l and 96 are fulcrumed in a bracket 98 on shaft TO-Figs. 2 and -l-and they are connected with an extension 99 of said bracket-F 1 and 3-by a spring 100 holding them against their cams.)

Drive shaft c carries fast and loose pulleys 101 to receive a driving belt controlled by the belt shifter 102.

Operation-As explained, from face plate i1, the lay structure obtains a movement which produces what is in effect a whipping-up of the filling to the fell of the cloth, the 'lay structure moving at accelerated speed forward and at slowing speed backward; substantially the same kind of movement is imparted to the warp to change the shed, since the lifting hook 26 derives its motion also from the same means as the laystructure (raising and lowering in alternation the two parts of the warp to form the shed, due to the lifting hook being swung alternately to right and left on descending, so as to lift first one and then the other harness jack 21). The upper half of the warp descends to the plane of the lower half to close the shed substantially simultaneously with the reed reaching its full forward position.

The picking motion occurs in altern, tion with the closing of the shed, since face plate L obviously rotates reverselv to face plate 7L and wrist pin j is passing over while wrist pin j is passing under the center of movement. As explained, ytlieadvance part of the picking movement is accelerating and its retracting part slowing in character, the same as in the case of the beating-up motion.

As to each complete cycle of movement of the two means-beating up and pickingeach begins while the other is in progress (to wit, about half-way of the cycle), so that time is saved and the wear and tear and vibration are reduced, especially as the speed variance in each instance is gradual in character.

Every other time the shuttlecarrier reaches its left-hand limit of motion it picks up the shuttle, leaving` it in the receiver the remaining times, the cam shoe 64 alternately preventing and failing to prevent automatic interlocking 0f the shuttle and receiver on succeeding picks due to its act-ive state being established (from shaft f) intermittently on each two cycles of picking movement. y

So long as the detector of the working shuttle remains held retracted by the filling its receiver 51 remains cooperatively alined with the shuttle carrier. But whenever the filling of such shuttle fails, and the shuttle therefore is left in its receiver with its detector protruding, said shuttle and its receiver are ejected and a fresh receiver and shuttle come into action thus: Hook 77 and lever 86h87 derive their downward Yimpulses (from cam shaft every two pickswhen the shuttle is in the receiver. The detector of the spent shuttle beino' in obstructing relation to lever arm 86, wehen the hook descends it is cammed by said arm overand engages the arm 74: (which at any other time it 'would miss), so that the rocker is first moved one way and then' (under influence of spring 75) the other, the spent shuttle and its receiver being delivered into hopper 76 and a fresh shuttle and receiver' coming into cooperative relation to the shuttle carrier in the way already explained,

Each element c 7c serves as means to confine the free end 0f the pitman i (i)'to a path of oscillating movement. There is another feature of this mechanism, however, which aifects the action of the means to be actuated, and that is the fact that the path of oscillatingrmovement of the free end 0f the pitman is relatively offset at the end thereof remote from the driver L (or t) due to the path being an arc around the fulcrum of 7c (or c) as a center, being offset in the present case in the direction of the acting lthrust of the actuated means, so that the whipping motion is obviously accentuated. Y

Having thus fuly described my invention, what I claim as new and desire to securefby Letters Patent is 1.
