SPECIFICATION forming part of Letters Patent No. 600,490, dated March 8, 1898. Application filed August 2, 1897. $erial N0. 646,743. (No model.)

To all whom, it may concern.-

Be it known that we, RANDOLPH OROMPTON and HORACE \VYMAN, of Worcester, county of Worcester, and State of Massachusetts, have invented an Improvement in Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention has for its object the production of a novel loom by which when the filling is broken or at fault in the shuttle used that the absence of the filling in the shed will immediately call into operation the devices which will supply upon the race of the lay a spare shuttle. This spare shuttle in this our present invention while the loom is running properly is supported upon a suitable feeding device held in its inoperative position near the breast-beam, and as soon as the filling fails and the failed shuttle gets back into its running shuttle-box the latter is lifted into its inoperative or abnormal position, so that the failed shuttle may be discharged through the open side of said running shuttle-box; but prior to the lifting of the said running shuttle-box into its inoperative position the shuttle-feeding device has been moved forward toward the advancing lay and has entered, preferably, a feeding-cell connected with the under side of the running shuttleboX, so that said shuttle-feeding device is raised positively with the running shuttleboX until the spare shuttle carried by it is put at the level of the race of the lay, when the spare shuttle is immediately picked or shot from the shuttle-feeding device onto the race of the lay. Before, however, the spare shuttle so put upon the race of the lay returns the running shuttle-box, its failed shuttle having been discharged from it, drops into its operative position to receive on its return stroke the spare shuttle just put upon the race of the lay, that shuttle continuing to run and weave so long as the filling is intact. The running shuttle-box in this instance of our invention has attached to it a box-rod, and said box-rod is raised and lowered by suitable box-rod or shuttle-box shifting or moving devices. The time of operation. of the box-rodshifting device may be determined wholly by or through the action of the filling-fork, it being operated only after the failure of the filling in the shed.

The particular features in which our invention consists will be hereinafter more fully described, and designated in the claims at the end of this specification.

Figure 1 is a left-hand end View of a sufficient portion of a loom with our improvements added to enable our invention to be understood, the shuttle-box guideway and the runningshuttle-box being in section.

Fig. Sis a detail showing part of thelay and its attached slotted mouthpiece; Fig. 9, a detail to the right of the dotted line m Fig. 1, showingthe shuttle-boX-shiftingmechanism. Fig. 10 shows a top viewof the shuttle-box guideway and part of the lay and reed, the latter being in horizontal section; Fig. 11, a detail showing the inner side of the shuttleway A the lay rock-shaft D the crank-shaft B, "the links B, connecting it with and to vibrate the lay; the gears B and B (represented only by dotted lines,) the gear B being fast on the crank-shaft and the gear B fast on the cam-shaft B the mutilated gear G, fast,

' crank-pin 6 which is adjustably connected by a link e with one end of a lever 6 pivoted at e and having at its other end a link e pivoted on a stud b extended from a col lar on the box-rod D the levere pivoted at e and adapted to be moved at proper times by a lever f pivoted at 6 to thus slide the said sliding toothed gear f 3 in order that the said crank-shaft a may be moved intermittingly for a half-rotation and be then stopped, and again moved for a half-rotation and stopped, such movement of said shaft eifecting the raising of the running shuttle-box and then its lowering, and the picker guide-rod A the picker A, it being adapted to slide in the ,slot A of the shuttle-box guideway, are and may be all substantially as shown in our application, Serial No. 646,742, filed August 2, 1897, so need not herein be further described. Herein the running shuttle-box a (see Fig. 2) has ears a, which enter .and slide in grooves of said guideway, and said running shuttlebox has abinder a acted upon by a spring a The running shuttle-box herein shown has 7 added to its under side a cross-bar a leaving between it and the under side a of the running shuttle-box what we have denomithrough which the spare .shuttle to be supplied to the race of the lay is passed at the proper times onto the said lay.

The picker may be actuated in any usual or suitable manner by any usual or suitable picker-stick (l -such, for instance, as common in the application referred to.

Ashuttle is supplied to the race of the lay through the open-end passage a of the feeding-cell when the running shuttle-box is in its inoperative or abnormal position, (shown in Fig. 4,) and in such position it will be understood that the bottom a of the running shutv tle-box has been lifted flush with the top bar a of the shuttle-box guideway, said bar forming the top of the picker-slot A and in such position of the running shuttle-box its open side a is fully exposed and uncovered to, thereby permit the discharge through said open side of the shuttle in which the filling has failed,said shuttle being discharged therefrom onto a suitable failed-shuttle receptacle m, located at the loom side.

The box-rod D is passed through a suitable hole in a box-rod guide 1), fast upon the rock-shaft D of the lay, by a suitable setscrew a, and at or near its lower end the said box-rod is provided with two suitable studs 1) and b said studs being in this present instance of our invention extended from a knuckle or sleeve 1), held in place between two nuts 2 3.

The stud b has connected to it the link e which is joined to the front end of the boxlever e before referred to, this latter lever and its operative parts before described, including the link 6 crank-shaft e and means to rotate the same intermittingly, constituting box-rod or shuttle-box shifting mechanism to raise and lower the shuttle-boxes and spare-shuttle feeder, to be described, and instead of the peculiar shifting mechanism herein referred to we may use any other wellknown shifting mechanism capable of operating the lever e or other usual connection attached to the box-rod to impart movement to said box-rod up and then down and leave the same at rest until the filling again fails in'the running shuttle-box.

The stud b is used to connect the spareshuttle-feeding device with the box-rod, so that it may be raised and lowered with it, said spare-shuttle feeding device as represented in this present invention being composed of a lever 5 having at its upper end a shelf or carrier b which may have at one edge one or more lips I)". At the rear side of said shelf we have mounted a pusher 12 to be described, it also acting at times as a binder. This lever 12 has at one side a roller or other .stud b and said lever may have connected with it below said stud a wedge-shaped block 9 said lever being free to play back and forth in a slot 12 of a guide 19 said guide being adjustably attached by suitable bolts 19 to a stand I), connected with the loom side.

In Fig. 1 the spare-shuttle feeding device is represented in its inoperative position, and it will be seen that the lever 79 is held back in the slot of the said guideway with the wedge-shaped projection 17* below the under side of said guide by a spring 12 connected 7 with a part of the 100111 side and with a pin on the said lever, said spring holding said lever and spare-shuttle feeder in its inoperative position.

The pusher or binder b is carried by arms 0, mounted upon a suitable pivot or rock-shaft 0, located below the shelf or carrier 19 said rock-shaft having a second arm 0 to which is jointed a link 0 the lower end of said link being attached to .an arm c fixed to the lay rockshaft D The shuttle-box guideway has attached to it by a suitable bolt a downturned projection a, it cooperating with the roller or other stud b of the lever b and constituting what is herein denominated as a locking device for the shuttle-feeding device.

The filling-fork c is pivoted upon a fillingfork slide-bar or carrier 0 which may be of any usual or suitable construction, it being eoonoo a adapted to slide or move transversely on the breast-beam, it being herein shown as moved in a guideway c", secured to said beam, and when the filling-fork is not tipped by the presence of filling in the shed the said'fillingfork slide will be moved backwardly, as will be described, the backward movement of said slide-bar acting upon an arm 0 fixed to a rock-shaft 0, extended across the loom from one to its other side, turning said rock-shaft and causing an arm 0 connected therewith to be moved toward the left in Fig. 1, said arm in its movement acting through a link 0 connected to the lever f, pivoted at 6 to turn said lever, causing it to act upon and turn the lever 6 thus shifting the sliding gear referred to to put its tooth 3 on the leg f in line with the gear G to immediately start in motion said shaft e it in its rotation immediately causing the box-rod to be started upwardly. The box-rod is started in its upward movement at that forward beat of the lay next following the operation of the fillingfork due to the failure of the filling, and with it is also started thelever b of the spare-shuttle-feeding device, and in its rising movement the wedge b of said lever acts against the inner end of the slot in the guideway Z1 causing'said lever to be moved toward the forwardly-moving lay, so that the projecting shelf or carrier of the shuttle-feeding device enters the feeding-cell under the running shuttle-box and places the spare shuttle in said cell, and at the same time the roller or other stud Z1 of the lever b passes behind the locking device 0 and locks the feeding device firmly in place with the running shuttle-box, (see Fig. 4,) this all happening substantially as the lay arrives at the end of said second forward stroke. lVhile the shuttle-feeding device with its shuttle is so released that the feeding deviceenters the feeding-cell of the running shuttle-box, the lay goes back, and the box-rod is then further raised to put the running shuttle-box in its inoperative position and permit the failed shuttle therein to be discharged from the rear open side of said running shuttle-box, and at the same time the spare-shuttle-feeding device, it lying in the said feeding-cell, is put into proper position with relation to the raceway of the lay to enable the picker at its next stroke to act and throw the spare shuttle from the spare-shuttle-feeding device and the feeding-cell onto the race of the lay, it being understood that the failed shuttle, as soon as the weft-fork operated at the opposite end of the loom to start the movement of the box-rod-shifting mechanism, came back into the running shuttle-box, so that said running shuttle-box, when it was elevated into its inoperative position, as just described, contained said failed shuttle ready to be discharged. The spare shuttle having been thrown from the shuttlefeeding device and feeding-cell at the said backward movement of the lay, the said boxrod is quickly lowered, this being done as the lay goes forward, and in its downward movement the roller or other stud 19 passes out from its engagement with the locking device, and the spring Z2 immediately assumes control of the lever I)", again putting the spareshuttle-feeding device in its inoperative position, leaving the running shuttle-box at the level of the race of the lay, so that as the lay is next moved backwardly the spare shuttle just thrown upon the race may be received in said running shuttle-box.

I-Ierein it will be noticed that the box-rodshifting device is not controlled as to its movements by or through a pattern mechanism, nor is it controlled as to its time of movement by or through the movement of the boxrod or device carrying the spare shuttle, but is controlled directly by or through the fillingfork and the movement of said fork after the failure of the shuttle to leave filling in the shed.

We believe we are the first to control the time of starting and stopping the movement of the box-rod-shifting gearing entirely by or through the filling-fork, and therefore this invention is not limited to the exact means herein shown for effecting such control; but instead we may employ any other usual or Well-known suitable mechanism, as it will be obvious that the connections between the filling-fork and the box-rod or shifting shuttlebox mechanism may be variously modified with only the skill of the mechanic and Without the exercise of invention.

We have attached to the end of the loom a shuttle-positioning device H, it consisting, essentially, of a bar having two extended arms it, having inclines it, upon which may rest the tips of a spare shuttle. (Shown by dotted lines in Fig. 5.) Said shuttle may be laid by hand upon the shelf or carrier 19 of the spareshuttle-feeding device when the latter is held stationary, as shown in Fig. 1, in its inoperative position, and in such position the pusher b stands between the said arms and next the spare shuttle at its side nearest the breastbeam.

When the spare-shuttle feeder is raised and moved to the left in Fig. 1 to be coupled with and moved with the lay, the change of position of the lever b causes the link 0 to turn the rock-shaft c and move the pusher,so that it acts against the said spare shuttle and pushes it in advance of it into the open space a, constituting the receiving-cell.

The filling-fork is herein shown as located at that end of the loom opposite where the spare shuttle is supplied to the shed, and this filling-fork is herein shown as operated by novel mechanism in a novel manner. For instance, we employ to reciprocate the fillingfork an operating device shown as a slide-bar d, it having an adjustable end d, provided with a heel d which enters and slides in the open inner end of the stand a, in which the filling-fork slide works, (see Fig. 6,) said heel constituting a support for the outer end of said slide-bar and preventing lateral movement thereof in the direction of the length of the breast-beam. This bar is shown as deriving its sliding movement from a cam d on the camshaft, said bar,as represented, being forked at its lower end (see dotted lines, Fig. 1) to embrace the shaft 13*, and a roller or other stud (1 carried by said bar, enters and is acted upon by said cam to move the bar. The free extremity or toe d of the said operating device is shaped to meet the downturned heel 61 of the filling-fork in case said fork is not tipped by the presence of filling in the shed The bar has a projection d, which normally stands under the breast-beam and prevents the free end of the bar rising too high. The adjustment of the end (2 on the said bar enables the position of the said operating device to be adjusted to a nicety to the tailpiece in its normal position. When the bar d acts to move the filling slide-bar outwardly in said stand, the rock-shaft (see Fig. 1) is turned, as described, to change the position of the sliding fork f 3 and so start the upward movement of the box-rod, and the shape of the said cam 01 is such as to retain the said bar in its forward position, with its end d in en gagement with the tailof the filling-fork, thus keeping the said filling-fork from returning into its normal position until after the shut tle-boX-rod-shifting mechanism has been 0perated sufficiently to lift therunni-ng shuttle- .box and put the spare-shuttle feeder under it, and about as the lay is completing its forward movement and the spare-shuttle feeder is beinglocked to the running shuttle-box the cam enables the bar to free the filling-fork slide, so that it again comes into its normal position under the action of the spring 01 (see Fig. 7) on said rock-shaft 0 (see Fig. 1) as the lay next goes back. The return of the filling-fork slide or carrier into its normal position enables said rock-shaft to efiect the turning of the lever f in the opposite direction to cause the tooth 3 of the leg f to be put out of the range of movement of gear G and cause the sliding fork f to be again changed in position to leave the shaft e at rest and the box-rod down, with the running shuttle-box in its operative position.

In our other application the sliding fork had two legs, each leg having a tooth, but herein we have dispensed with one of said legs, and we put the. tooth 4, (see Fig. 1,) which in our other application was on one of said legs, di-

. rectly onto the gear f and as a result of'such change the said gear f 3 is rotated a half-rotation, and the tooth 4. enters the space between the two series of the teeth of the gear G, and the gear f and shaft e remain at rest for an instant until the second series of teeth of the gear G meet the tooth 4, when the gear f 3 and shaft 6 are again given a semirotation', the tooth 3 having been put into its inoperative position, Fig. 9, letting the second series of teeth of gear G run out of mesh with the teeth of the gear f at the space left by dis placing the tooth 3, and then the said gear f remains at rest until the filling-fork is again moved by the failure of the filling.

The mouthpiece g at that end of the lay nearest the running shuttle-box is slotted, as at 9 (see Fig. 8,) for the passage of the filling-thread 25, connected with the bobbin in the spare shuttle, the outer end of said fillingthread being caught (see Fig. 12) on a suitable stud or post 9 fixed to the loom-frame or to the breast-beam and extended over the cloth between the usual temples. The filling between the spare shuttle and the said stud is extended over a rest 9 which rises from one of the arms of the spare-shuttle-positioning device, (see Figs. 5 and 5%) said rest supporting said filling at a proper height to aid it in its entrance into the slot g of the mouthpiece. When the spare shuttle is thrown from the spare-shuttle feeder onto the race of the lay, the filling between the said shuttle and its held outer end passes through the opening a? of the receiving-cell and the slot g of the mouthpiece, and the shuttle enters the shed, leaving, however, the end of the filling yet connected to said stud and extended therefrom to the selvage of the fabric being Woven, and said filling is thus laid or presented on the top side of the cloth being woven, as shown at g, so as to pass readily through the usual temple T (only partially shown in Fig. 12) along with the cloth, said projecting end being thereafter broken off by hand or otherwise. The lips 12 at the inner edge of the shelf or carrier b of the spareshuttle feeder, as the latter is put under the running shuttle-box to enable its spare shuttle to be thrown onto the race of the lay, enter spaces 9 at the inner face of the shuttle box guideway at each side of the ali ningplate 9 fixed to the inner side of said guideway and adapted to receive against it the rear side of the shuttle to be thrown onto the raceway, the face of said plate being substantially in the same vertical plane as the faces of the dents of the reed i and alining any shuttle going onto the race of the lay. This alining-plate is necessary, because the running shuttle-box has not, as heretofore, any vertical side wall against which the side of the shuttle may be put in alinement with the face of the reed-dents before the said shuttle is struck by the picker to throw it across through the shed.

The shelf or carrier U (see Figs. 1 and 5) is considerably wider than the spare shuttle in cross-section, and the spare shuttle rests on the outer portion of said shelf, as in said figures, when the spare-shuttle feeder is in its inoperative position, and at such time the pusher stands at an inclination, the lower edge of the shuttle resting against said pusher; but when the spare-shuttle feeder is started upwardly with the box-rod after the failure of the filling in the running shuttle-box the link 0 held down at its lower end by the lay rocker-shaft, causes the pusher to be turned to act against the shuttle, and the said pusher is put into substantially upright position, and the lips 1), extended from said shelf, enter the spaces g at the end of the alining-plate g and the pusher then acts on the said shuttle as a binder to put said shuttle closely against the said alining-plate, so that it maybe directed properly onto the lay for a proper straight flight.

The invention herein shown and described is not in all cases limited to the particular construction shown for the operative parts, and while we have herein described substantially all the parts of a fully operative .loom it will be understood that the use of less than all the parts shown and described is within the scope of our invention as designated in the claims covering operative combinations of only a part of said devices, and our invention in all the minor details includes the use of any well-known mechanical equivalents.

The shuttle-box at the opposite end of the lay, but not shown, may be of any usual or known character.
