SPECIFICATION forming part of Letters Patent No. 529,940, dated November 27, 1894.

Application filed December l2, 1891- -Serial No. 414.831- (No model.)

To aZZ whom ama/y concern.-

Be it known that I, JAMES H. NOETHROP, a subject of the Queen of Great Britain, but at present residing at Hopedale, county of Worcester, 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 to improve and simplify that class of loom shown in United States Patent No. 454,810, granted to me June23, 1891.

In the loom described in that patent the bobbins to be supplied automatically to the shuttle in the shuttle-box of the lay Were i placed in a hopper down which they slidfby gravity, the end most bobbinlying just below the pusher when the latter was in its normal or elevated position.

In looms wherein the bobbin or bobbins in shuttle-cases are placed in a hopper one against another, the bobbins or the bobbincases depending for their movement upon gravity and sliding in a case, difficulty is experienced in bringing the bobbin directly into proper position with relation to the pusher used to put the bobbin into the shuttle. I have for the first devised an apparatus for positively bringing each bobbin into position under the pusher, my lsaid apparatus comvprehending an intermittingly operating bobbin-feeder devised to receive and support independently the bobbins to be carried by the feeder, the latter being preferably so constructed as to positively hold both ends of the bobbinin the movement of the feeder to put the bobbin under or Within the range of movement of the pusher.

With my improved bobbin feeder I have combined a guard or retainer, which prevents the escape of a bobbin except at the proper point.. The feeder has co-operating with ita stop, against which rests the head of the bobbin next to be acted upon by the pusher. The vdisk which serves to hold the tips of the bobbins has a series of spring-like or yielding catches. l

In the patent referred to the weft threads were connected with a stud, located outside the hopper, and as the bobbins descended in the hopper, the weft was unwound therefrom, and means had to be provided by which to take up and care for the slack weft thread, and prevent'the same from becoming entan` gled; but herein, in order to obviate this difficulty, I have combined With the bobbinfeeder a weft-end-support which is moved with the bobbin-feeder, and by which the formation of slack thread is avoided.

. In the patent referred to, the bobbin to be transferred from the hopper into the shuttle- Wbox, was acted upon at its head end by a pusher, and sometimes in the rapid running of the loom difficulty has been experienced because ofthe failure of the point end of the `bobbin to get into the shuttle at the proper time.

To overcome this difficulty I have devised a pusher having a finger extended laterally therefrom, so as to occupy a position just over and near the tip end of the bobbin,

the said finger having its acting face located in a higher plane than the acting face of that 4part of the pusher which contacts with the tion the finger acts upon and positively dislodges the tip of the bobbin from the device holding it. I

The bobbin-feeder is herein represented as composed of two disks having a series of notches or pockets, the disks being attached to ay sleeve mounted upon a fixed stud, one disk or the sleeve having a ratchet adapted to be engaged by a pawl pivoted or mounted upon a spring-actuated paWl-carrier deriving its motion,'in this present instance of my invention, from a projection carried by the lay. This ratchet has co-operating with it a detent which prevents retrograde motion thereof. I have also combined with the said bobbinfeeder a stop against Which is carried the head of the bobbin next to be acted upon by the pusher, and when the bobbin contacts with this stop, the end of the pawl, by its engagement with a tooth of the ratchet Wheel, acts to keep up the end of the paWl-carrier nearest the lay, so that the said pawl-carrier IOO cannot be vibrated to move the bobbin-feeder until the pusher has acted to push the bobbin from the bobbin-feeder. Thepusher having acted, the spring which moves the pawl- 'carrier immediately acts and moves the carrier and the pawl, causing the feeder to be rotated or moved in a circular direction, sufficiently far to bring the next bobbin in the shuttle against the said stop.

In United States Patent No. 454,810 heretofore granted to me, I have shown What I have therein designated as a positioning device, it acting at proper times upon the innermost tip of the shuttle to position the same correctly in the shuttle-box and with relation to the pusher, to receive a bobbin.

In my efforts to leave the raceway of the loom as free as possible, I have devised a positioning device, which, at the proper time is made to engage a notch at the rear side of the shuttle which is about to receive a bobbin, said device act-ing to push the said shuttle backwardly into its correct position in the shuttle-box provided the said shuttle is not in its proper position to receive the bobbin from the feeder.

The positioning device is herein represented as deriving its initial motion from an arm or projection upon a rock-shaft actuated by the filling fork-Slide.

In order to enable the positioning device to reach the shuttle, the rear side of the shuttle box has been provided with a slot. y

To avoid any possibility of the picker-stick striking the bobbin when the loom is running at high speed, I have provided the lay at the under side thereof and near the end of the slot in which the picker-stick Works, with an arresting device, which arrests the head of the bobbin after the same has been ejected from the shuttle and passed through the slot in the shuttle-box.

Arresting the head os the bobbin enables the tip thereof to be turned down so that its point may be directed toward the bobbin receptacle, and, to prevent the tip of the bobbin from getting into the path of the pickerstick, I have combined with the arresting device a lump or projection Which deflects the bobbin laterally.

The lay, immediately below the arresting device, is provided with a chute which receives upon it the ejected bobbin, on its way into the bobbin receptacle. Herein I have combined with the pusher a locking device for the bobbin-feeder, so that the pusher, as

it is moved to take a bobbin from the bobb in- 1 feeder and put it into the shuttle, Will enable the locking device, actuated by a suitable spring, to engage the said bobbin-feeder, so that said feeder cannot be moved While the pusher is in operation, or While it is acting to put a bobbin into the shuttle, the upward movement of the pusher into its normal position causing the locking device to release the bobbin-feeder.

In the class of looms made the subject of this invention and claim, the object is to entraen) able the same to be run at high speed, and to dispense with as much attendance as possible. In doing this, numerous difficulties arise which do not occur in ordinary looms.

In that class of loom represented in United States Patent bla-154,810, dated June 23, 1891, wherein provision is made for automatically supplying a shuttle with a bobbin to replace a bobbin when the thread with which the bobbin is threaded has been broken or exhausted, and wherein the threadmof the newly supplied bobbin is automaticallythreaded into the delivery eye ofthe shuttle, it sometimes happens that the thread of the bobbin last inserted in the shuttle, fails to be threaded into the delivery eye thereof at the first shot of the shuttle through the shed, and in such event, the weft fork mechanism acts and causes the full bobbin just put into the shuttle to be ejected before its thread has been at all used, and the loom will continue to run, and will, at every other pick, move the pusher, take a bobbin from the hopper or other source of supply for bobbins and put it into the shuttle, this operation being continued until the thread from the bobbin has been left in the shed in suitable position to tip the filling fork, and if the filling fork is not tipped by the weft the op- .eration will continue until all the bobbins have been taken from the hopper or other source of supply for bobbins, and during such operation no cloth will be woven.

The loom referred to Will continue to run even after the bobbins have been taken from the hopper, for the weft fork mechanism instead of acting as in ordinary looms to effect the stopping of the loom when the weft fails in the shed, is made instrumental only to determine the time at which the pusher shall be actuated to put a bobbin into the shuttle.

In ordinary looms for Weaving cotton cloth, Whenever the weft fails, the weft fork is not tilted, and consequently the tail piece of the weft fork is caught by the usual weft hammer and the weft fork slide is moved outward toward the front of the breast-beam to eect the stopping of the loom through a knock-off lever and usual Vcontrolling mechanism, not shown, of which there are many variations in use, all of which operate in substantially the same manner, but as above stated it will be remembered that the weft fork mechanism in said patent performs a very dilerent duty.

`For this my present invention I have invented appliances whereby the weft fork not only controls the movements of the pusher, but also effects, by its movements, the stopping of the loom under circumstances to be hereinafter more fully described. To effect this desirable result I have invented a novel weft fork mechanism which has been so devised that it is not made fully effective to stop the loom or operate the knock-0E lever thereof until after more than one action of the lay, the rst failure of the weft fork to be tilted by the presence of the weft against it, being utilized to effect a primary movement IOO IZO

. the movement of the pusher.

of the weft fork, sufcient, however, to put into position the parts upon which depend In case, however, the weft should fail at one shed and a bobbin should be inserted into the shuttle, and the weft from said bobbin when the shuttle is thrown across the shed should fail to be left opposite the weft fork, then in such case the weft fork for a second time will not be tilted, and the slide-bar carrying it will be given an additional or secondary movement' sufficient to knock off or stop the loom; but in case the weft from the new bobbin last in-l serted in the shuttle should be presented in position to tilt the weft fork, then the movement ofthe weft-ham mer will restore the weft fork mechanism into its normal condition and enable the loom to be run. f To effect this desired result I have provided the weft-fork slide with what I term a trigger, said trigger being adapted to be set at that outward movementv of the weft fork slide which is effected by the absence of weft at the tilling fork, and which movement is used to indicate that the pusher must act to put another bobbin into the shuttle, and if the shuttle, it having received another bobbin, fails at the next shot to leave weft in front of the wet' t fork,

then said trigger effects the knocking off of the loom to stop the same, butA if the shuttle, it having received a fresh bobbin, leaves a weft to meet the weft-fork, then the said trigger will be restored automatically into its normal position. In the embodiment of my invention as herein illustrated, the weft hammer is employed to restore the weft-fork slide. This trigger, through suitable appliances, such asa knock-off lever between it and the shipper handle, is made at the proper time to effect the release of the shipper handle, and through the usual means, stop the loom. y

I have combined with a binder-operating rock-shaft an arm which engages one part of a weft-parter, connected to and moving with the lay, the said arm, actuated by the movement of the rock-shaft, in turn moved by the shuttle-binder in usual manner, serving to close the weft-partei' at all times while the shuttle is in the shuttle-box of the lay.y

In the accompanying drawingsz-Figure 1 is a partial front elevation of a sufficient portion of a loom containing my improvements to enable my invention, to be understood, the breast-beam and some of the shafts being broken out centrally to save space upon the drawings, the lay being entirely omitted because it is shown in other gures to be referred to. Fig. 2 is a longitudinal sectional detail of the bobbin-feeder and weft-end support and holder, the gure showing one bobbin in position. Fig. 3 is a partial right-hand side elevation of my improved loom, the weftend support and holder and theout'er disk of the bobbin-t'eeder being both partially broken out to show the head-holding disk of -the feeder and two bobbins therein, the gure also showing the notches which receive the heads ot'the bobbins. Figs. 3a and 31 are details of the pusher. Fig. 4 is a detail of the stand for the bobbin-feeder said figure showing the ratchet for rotating the same. Fig. 5 is an opposite side view of the said stand. Fig. 6 is a sectional detail showing the breast beam, the weft-fork, its actuating hammer, and the lay. Fig. 7 is a top or plan view of one end ot' the breast beam, the weft-fork, and some ot' its co-operating parts. Fig. 8, shows details of the devices employed in actuating the positioning device; Fig. 9, a detail View of the weft-partei'. Fig. 10 is a front elevation of that end of the lay and shuttleboX which is hidden by the bobbin-feeder in Fig. 1. Fig. 1l is a top orv plan view of that end of the loom at whichis situated the shuttlc-box which is to be supplied with bobbins automatically, the said figure showing but part of the lay and the breast-beam together with the stand or support for-the bobbinfeeder, the bobbin-teeder being however removed, the stud on which it rotates being broken off. Fig. 12 shows a portion of the shuttle to illustrate the notch in its rear side which is engaged by the pusher. Fig. 13 shows a portion of the head-holding disk of the bobbin-feeder, stand, and locking device for the feeder. Fig. 13a is a detail of the feeder locking device; Fig. 14, details of the trigger and the end of the releasing lever; Fig. 14', a View of the trigger and plate, Fig. 14, looking in the direction of the arrow; Fig. 15, aside elevation and section of the end of the releasing device next the trigger. Figs. 16, 17, and 18, are respectively a side elevation, plan view, and section in the line y-y (Fig. 16), of the shuttle-arresting and delecting plate at the under side of the shuttlc-box, and Fig. 19 is a section across the take-up' detentf7 in the line 9312, Fig. 3.

The loom frame A has in suitable bearings a crank-shaft A', provided with a toothed gear A7, which engages a toothed gear A8 on and rotates the under shaft A9, havingacam A17, which acts upon the arm A18 of the wefthammer A12.

The breast-beam, lettered A40, has upon it IOO a guide A24 for the weft-fork slide A23, upon the forward end. of which is pivoted the weftfork A2, having, as represented in Fig. 6, at its rear end a downturned tail of usual shape.

The outer end of the weft-fork slide acts against an arm A25, fast on a rock-shaft d', extended across from one to the other side ot' the loom. As the lay comes forward for the reed to act, should the weft be absent in front of the wett-fork A2222 thenthe said fork will relnain down and its tail-piece will-be struck by the weft-hammer A111, which will cause the weft-fork slide A23 to be moved to- Ward the outer side of the breast-beam, so

IZO

to put into operation the pusher which is instrumental in transferring a bobbin into the shuttle.

The parts above referred to specifically by letter, are substantially as in the patent referred to. as are also the picker staff A15, and the self-threading shuttle S, with the exception that the shuttle has at its rear side a notch S2, t0 be described.

The bobbin-feeder herein to be described consists essentially of a disk or plate a, having a series of notches or pockets 2 (see Fig. 13) to receive the heads of the bobbins b, one of the said notches being shown in Fig. 3 in full lines and another in dot-ted lines, and a second disk or plate a', herein represented as having a series of grooves and provided with a series of springs a2, the said disk and its parts serving to hold the tip orsmall end of the bobbin.

The hub a3 of the disk a is provided with asuitable dog a4, made as an L-shaped finger, extend edthrough a slotin the hub, the said finger entering an annular groove d5, made in a stud a, lixed with relation to the stand a7 by means of a nut as, so that the said hub and disk may be rotated on the said stud intermittingly, the disk or plate a having a series'of rachet teeth a9. Shown best in Fig. 4.

The outer end of the stud ais surrounded loosely by a sleeve d which is forced tightly into the open end of the hub as, and upon sleeve d is secured by a screw 3, see Fig. l, the hub d10 of the disk or plate a which holds the tips of the bobbin, the said sleeved having also fast upon it by ascrew 4 a weft-endsupport b', the latter having in this pres` ent embodiment of my invention a wett-endholder shown as a central stud b2, to which will be secured the free ends of the weftthreads coming from the bobbins b, mounted separately or independently in suitable bearings, pockets, or notches in the bobbin-feeder, the said weftthreads, at a point between the bobbins and the weft-end-holder, resting in suitable notches, shown best in Fig. 3, in the periphery of the weft-end-support b', the weft-end-support and the said holder, one end of which is tted into'the open end of the sleeve d, rotating in unison with the bobbinfeeder.

The plate or disk a has notches or grooves 5, and opposite the said notches are spring fingers a2 attached by bolts 7 and prevented from lateral displacement in the notches by guards 8, each guard preferably forming a part of the plate a and being shaped like the three sides of a square.

The `foot of the stand a7, see Fig. 1, is attached by suitable bolts 10 to a block or plate resting upon the breast-beam A40, the said stand for a portion of its periphery, see Figs. 4 and 5, having a guard or shield c, attached by bolts 12, the said shield acting to overlap somewhat the ends of the heads of the series of bobbins supplied to the bobbin-feeder, the endmost bobbin of the series always resting against the stop 13, see Figs.`3 and 5, located at a short distance from the lower end of the guard, the bobbin when in such position, see Fig. 3, being directly under the pusherf to be described, and directly over the shuttleboX of the lay, when the latter is in its forward position toward the breast-beam. The stand a" has, see Fig. 5, a headed stud 16, see Figs. 2 and 4, which forms the fulcrum for a pawl-carrier e of somewhat peculiar shape, see Fig. 4, it being provided with a hub at one end, shown by section in Fig. 1],in which hub is mounted a pin 315, carrying a springpressed pawl e', which engages the teeth of the ratchet wheel a9, said pawl being operated by a spring 316 surrounding said pin 315 and connected at one end to the pawl-carrier and at its other end to a hollow collar 317 secured to said pin, as in Fig. 11, said pawl-carrier having a tail-piece e2, a spring e3 acting at one end on the said pawl-carrier and iixed at its other end with relation to the said stud 16 serving normally to move the pawl-carrier in a direction to rotate the bohbin -feeder and keep against the stop 13 thereof the endmost bobbin of the series of bobbins sustained in the feeder, the pawl-car rier being moved in the opposite direction at the completion of the backward stroke of the lay by means of a roller or other projection e4, see Fig. 3, carried by the lay, it acting upon said tail-piece.

The ratchet wheel ai is prevented from being moved backwardly by a suitable detent e5.

It will be understood that inasmuch as the pawl e is moved by the projection e4 on the lay to carry the pawl back over the teeth of the ratchet wheel a9, the said pawl will engage a ratchet tooth and the tail-piece e2 will remain elevated or out of range of the projection e4 as long as the endmost bobbin b rests against the stop 13; but as soon as the said bobbin has been pushed out from the bobbin-t'eederinto the shuttleS by the pusher, then the spring e3 immediately acts upon the pawl-carrier and rotates the bobbin-feeder at one stroke the distance necessary to put the endmost bobbin of the series, no matter how far distant from the said stop, against the said stop.

The operator will supplythe bobbin-feeder with bobbins as they may be needed, it being necessary to visit the loom for this purpose only when the bobbins in the hopper are nearly exhausted. To do this the operator will take a bobbin in his hand and at a point behind the end of the guard c will put the head of the bobbin in an empty pocket or notch 2, and then slip the tip end of the bobbin into a notch of the plate a. The stand a7 has also a suitable hole or opening for the reception of the headed studf, see Figs. 1 and 3, upon which is mounted the hub of the pusher f', the said pusher, shown separately in Figs. 3 and 3b, being shaped at its front end to present a portion, as 20, to act against the head of the bobbin, and a linger, as 2l, to

IOC

IIO

act against the tip of the bobbin, the'surface 20 being in a somewhat lower horizontal plane than the end of the finger 2l, so that the head lof the bobbin is tirst struck and carried to'- ward or into the open top of the shuttle S,

and thereafter the linger 21 acting against the tip of the bobbin takes it out from the tip-holding device of the disk or plate a', in case the tip does not start promptly.

The provision of shaping the pusher so that it acts on both the head and tip of the bobbin insures greater certainty of operation of the parts and accuracy of insertion of the bobbin into the shuttle, which shuttlehas in practice bobbin holding jaws or devices and a selfthreading slot, all vas provided for in said United States Patent No. 454,810.

One end f3 of the pusher 'has jointed to it atf4, a trip f5, herein represented as joined by an adjustable connection or rod f6, with the detent]7 which acts to hold the ratchet wheel f8, connected with or forming part of the take-up mechanism whichl may be of any usual construction.

The rock-shaft d has near its outer or righthand end, see Figs. 1 and 3, an arm d4 suitably shaped at its end to engage with or under a pin or projection 310, see Fig. 3, extended from one side of an arm d pivoted at e160, and on which arm slides the detent f7, and, as a result thereof, whenever the weftfork slide is pushed backward, the weft being absent, as described, the rock-shaft d will be turned andthe said nger d4 will lift the detent f7, thus releasing the take-up,and at the same time the trip f5 will be put into j the range of movement of the bunter C2, at-

tached to the lay and common to the patent referred to, the said bunter during the for ward movement of the lay meeting the said trip f5 and actuating the pusher, as provided for in the said patent.

This invention is not intended to be limited to the exact form of devices employed for insuring the placing of the trip f5 in the range of movement of the bunter when the weft is absent at the weft fork when the reed moves forward to beat the weft into the shed, and instead thereof I may employ any other usual or suitable devices which will operate said trip atl the proper time either by or through the weft-fork slide, or by suitable initial devices or by devices of the actuating train or other devices, substantially as provided for in Patent No. 462,919, dated November l0, 1891.

In Fig. 19 I have shown a section of the take-up detent in the line w12 Fig. 3. This detent is composed of a`n arm d4 which forms a track to guide the detent f7 mounted loosely on the said arm, said detent being of usual construction, a lump d423 at the free end of the said arm keeping said detent in place.

The pusher having been caused to push a bobbin from the bobbin-feeder into the shuttle when the latter was directly under the bobbin,-the lay being forward as provided for in said Patent No. 4`54,810,-a spring 22,

one end of which is connected with the pusher and the other with the stud f referred to, acts to quickly elevate the pusher into its normal position.

By the device described the bobbins are brought positively into a predetermined or delivery position against the stop 13, andthe weft ends are not tangled, nor is any slack formed therein, due to the movement of the bobbins from the point in which they are placed in the bobbin-feeder and their arrival at the stop. f

Referring now to Figs. 10 and 11, g represents the shuttle-binder arranged at the front side of the shuttle-box; g', its actuating spring, and g2 shows a plate attached rigidly to the lay and forming the rear side of the shuttlebox, said plate having an overhanging lip or flange, asgi, and having at its innerside a notch through its side in order that the positioning deviceyh,shown as an adjustable or two-part arm, mounted upon a stud h of a lever h2, may, at the proper time, be made to move into the shuttle-box through the said slot, and

Vengage the notch s2, or a shoulder forming a part thereof, in the rear wall of the shuttle, and push the said shuttle toward the outer end of the shuttle-box, in case the shuttle should be out of position or should have rebounded, and in this way it is made certain that the said shuttle will always be put in exactly the proper position to receive'the bobbin b as the latter is pushed out from the bobbin-feeder into the shuttle as provided for in said Patent No. 454,810, the spent bob` `bin or the bobbin which it is desired to remove and replace by another being pushed out through the shuttle-box into the receiver E, which may be a box or receptacle of any usual character.

The binder g ofy the shuttle-box is acted upon by a binder higer g4, forming part of a rock-'shaftg5, monted in bearings fixed to the lay, and said rock-shaft has, as herein represented, a linger g6 which enters the notched endk 97 of a weft-parter g8, pivoted aty in suitable manner to a collar k7, suitably secured or ixed upon the stud h3, so thatthe said spring normally acts to keep aprojection ha on the arm h2 against a projection h9 of the plate h4.

Viewing Fig. 8, it will be seen that the proj ection h8 overlaps somewhat the stop projection hg. I

It will be understood that the shuttle needs to be put into exact position with relation to IOO IOS

the pusher only as the latter is to be actuated to put a bobbin into the shuttle, then in the shuttle bemand to actuate the positioning device at this time I have provided the rock shaft d near the side of the loom where the pusher is situated with an arin d, see Figs. l and 8, which is lifted whenever the rock shaft d is turned as described by the weftfork slide to start in motion the pusher, said arm di acting on the projection hs, thus mov ing the lever h2 in the direction of the arrow shown in Fig. 11, causing the positioning device h to act quickly and put the shuttle into position.

A suitable spring, as 7112, connected with the positioning device at one end and at its other end with the lever h2, serves normally to keep the free end of the positioning device in contact with-or in proper position with relation to the slotted back-plate g2, so as to pass through said slot and engage said Vshuttle while the positioning device is being moved in the direction of the arrow near it in Fig. 11.

As has already been stated, it is of great moment to obviate bad places in the cloth caused by the failure of a newly-inserted bobbin to lay its weft properly in the shed at the rst pick of the shuttle containing the new or fresh bobbin. To overcome this trouble I have devised appliances which I will now describe and which I have combined with the lay and with the usual weft-fork slide.

' I have attached to the weft-work slide A23, by a suitable screw 30, a small stand or plate A31, upon which I have pivoted at 32 a trigger 33, shown as an elbow lever. See Figs. l, 7, and 14. I have also attached to the top of the brcast-beain by a screw 34 a trigger-mover 35, which somewhat overlaps the weft-fork stand A2, so as to be in the range of movement of the short arm of the trigger. I have pivoted upon the lay at 36 a k neck-od lever 37, it having pivoted upon it near one end at 312 a latch or dog 3S, the opposite or left-hand end of the lever, see Fig. 7, resting just above the usual notched holding-plate 38X attached to the breast-beam, and next the shipper handle 39, herein shown as pivoted at 40 and having its lower end extended into an eye or otherwise suitably connected loosely with a belt-shipper 41, of any usual or suitable construction and provided with suitable wires or arms 42 to control the belt employed to drive the loom and place it either on the fast or loose pulley, according to whether the shipper lever is in its usual notch in the plate 33 or is out of said notch.

Figs. 1 and 7 show the shipperlever in its usual notch.

Referring now to Fig. 7, let it be supposed that the weft-fork slide is being moved backward by the hammer, the weft being absent opposite the weft fork, and in such movement the short arm of the trigger 33 will meet the trigger-mover 35 and the said trigger will be turned thereby about its pivot 32 into the dotted line position Fig. 14, causing the long arm of the trigger to pass under the right-hand end of the knock-oft lever 37, where, acting against the beveled under side, see Fig. l5, of `the latch 38, the trigger will lift the said latch and not turn the knock-off lever about its pivot. As the weft-ham mer A1g is moved back away from the breast-beam the weftfork slide will be thrown forward toward the lay, in usual manner, but the trigger 33 will remain in the position in which it was put by contact with the trigger-mover 35, so that if the weft-fork slide should again be operated by the weft-ham mer, as when the weft-fork is not tilted by weft, then the said trigger, at the second movement of the wett-fork slide toward the front of the breast-beam will strike the side of the latch 38 of the lever 37, and turn the said lever to knock the shipper handle from its holding notch in plate 38X, allowing a suitable spring 50, see Fig. 1, connected with said lever and with the stand 5l, to move said lever in the direction to shift the belt from the fast to the loose pulley and stop the loom. Should, on the contrary, the shuttle just thrown through the shed, said shuttle containing the new bobbin, leave weft in front of the weft-fork, so that it will be tilted in usual manner, then the weft hammer in its movement, it being moved once for each beat of the lay, will strike the heel 53, see Figs. 6 and 14a, of the triggerand turn the said trigger back about its pivot 32 into the position shown in Fig. 7. In this way, whenever the first shot of a shuttle containing a new or fresh bobbin does not leave its weft in front of the weft-fork, the loom will be automatically stopped; but, in case said weft th read is left in front of the said fork, the loom will continue to run notwithstanding many changes of bobbins in the shuttle.

The end of the lay containing the shuttlebox has at its under side a casting m, see Figs. 10 and 16, having at its outer end an ear 'm' which is suitably bolted to an ear m2 forming part of the shuttle-box bottom, the opposite end of the said casting'or deflecting plate having a suitable threaded hole to receive a bolt ma, extended into or over a depending ear of the bottom of the shuttle-box. This plate has, near the side of the loom, a cup-shaped or socket-like bobbin-headarresting device m4, and at a short distance therefrom to the right is a projecting rib m5, the said bobbin-headarresting device being directly under the slot in the bottom of the shuttle-box through which IIO the bobbin ejected from the shuttle by an incoming bobbin passes, the head of the bobbin contacting directly with the said bobbin-headarresting device, while the bobbin at a short distance therefrom acts against the rib m5, so that the said bobbin has its head arrested and its body thrown to one side away from the path of movement of the picker stick, which is located at the rear side of the plate m, and consequently the bobbin cannot possibly get in the way of the picker stick so as to be struck thereby. This plate m and its y attached parts are shown enlarged in Figs. 16

to 18, both in side elevation, in top view, and in section in the line y-y. In these views it will be seen that the plate has a recess in which is placed a buffer n, which may be of sole leather or other suitable non-metallic material, against which the picker stick may strike at the end of its inward motion.

Referring to Fig. 13,11 represents a locking device for the bobbin-feeder, the said locking device, shown best in Fig. 13, consistingof a plate having a notch 80, see Fig. 13 and a iinger 81 said plate being connected to a short shaft 82, see Figs. 4 and 1l, extended through a hole in the stand 0,7 and having applied to it a collar 83, to which is attached one end of a suitable spring 83X the other end of the spring being attached to the stand a7, so that the spring acts to keep the notch 8O of the locking device in engagement with one of the projections between two notches 2 of the plate or disk a, especially as shown by full Yline Fig. 13, it so engaging said plate to lock the bobbin-feeder when the pusher is being moved to transfer a bobbin therefrom into the shuttle.

The pusher at itsrear side has a projection 44, see Fig. 3a, which, as the pusher rises, acts against the finger 81 of the locking device, turns it against its spring 83X, and releases the disk or plate a.

In the operation of the weft-parting device, let it be ksupposed that the .bobbin has just been put into the shuttle. Now the shuttle, acting upon the binder g, moves the latter outwardly so that it, acting against the binder finger g4, closes the weft-parter. The picker stick is moved to throw the shuttle Ythrough the shed while the lay is at its back stroke, and while the shuttle is in the shuttle-box at ing herein shown, the lay is moved forward to beat in the filling, but the presence of the shuttle in the said box, it having in practice a binderlike that already described, acted upon by a like nger connected to the shaft g3, said parts not being herein shown because a mere duplicate of the parts already shown, prevents the opening between its members of the weftparter for the the reception of the thread, at that time between the selvage and the threadsupport b. The lay, having been moved forward, is started back, and when the crankshaft is near its top center the lay is put half way back, the shed is formed in the usual manner, and the shuttle, previously thrown as stated across the loom, is thrown back into the shuttle-box from which it started and where it received the bobbin then within it. As soon, however, as the shuttle on its return, as above stated, leaves the opposite shuttle-box, the binder-rock-shaft g5 is immediately left free to turn and open the weft-parter, so that as the lay continues to move on its backward stroke away from the fell, and while the shuttle is in its flight from the opposite back box to the shuttle-box where it received a bobbin,

the then open weft-parter receives between its members the previous shot of weft, then extending between the selvage and the weftend-support and holder, and as soon as the shuttle gets into its home box the binder is actuated, as before described, to effect the closing of the weftparier upon the weftthread, so that as the lay comes forward again the said weft-parter, acting'upon the weft thread, breaks the same olf.

, Believing myself to be the first to employ a rotating or endlessly-movingbobbin-feeder to receive, contain, and positively carry forward a series of bobbins, in order that they may be properly presented between a pusher and a self-.threading shuttle in a shuttlebox, this` invention is not intended to be limited to the exact shape shown for'the bobbin-feeder, or to the exact mechanism shown for imparting movement to the feeder.

Prior to my invention I am not aware that a weft-fork forming part of a weft stop-motion has ever had combined with it means whereby the weft-fork slide-might be moved once as when the filling was absent and not knock 0E or stop the loom, but knock off or stop the loom ata second movement of the weft-fork slide'immediately following the rst movementfreferred to. Nor am I aware that a weft-fork has ever had combined with it adevice which, at one movement of the slide after the absence of ythe weft, would set a trigger, and, a weft having beencorrectly supplied to the shed, a second device to act upon the said trigger and restore it to its normal or inoperative position to thus prevent the stopping of the loom. Hence this invention is not intended to be limited to the exact form of trigger referred to, or to the means for mov-` ing it, as it will be obvious tothose skilled in the art that various forms of trigger devices, operating upon substantially the same principle, might be devised without departing from my invention; and the restoring of the trigger to its normal position, even though effected by some moving part ofthe loom other than theweft-hammer, would, I consider, be within the scope of my invention.

It will .be noticed that the bobbin-feeder and the pusher are so devised and combined that vthe bobbins are arranged in the arc of a circle, the bobbins are supported at their opposite ends, the sides of the-bobbins next the center of rotation of the bobbin-feeder are uncovered, and the pusher enters, stands, and works inside the periphery of the bobbinfeeder and within the circle corresponding with the arc of the circle in which the series of bobbins are held, the bobbins being presented in succession between the center of rotation or motion of the bobbin-feeder and the shuttle in the shuttle-box.

I am aware, prior to my invention, that looms have been provided with rotary shut- IOO IIO

tlc-boxes, which I do not claim, and I disclaim any bobbin feeder wherein bobbins or bobbin cases are arranged in a chute or guideway one against another' and adapted to be moved forward by gravity, as the lowermost bobbin or shuttle-case is removed from the bottom of the pile.
