FILLING- STOP-MOTION.

Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed August 9, 1907. Serial No. 387,750.

zen of the United States, residing in Lewiston, in the county of Androscoggin and State of Maine, have invented an Improvement in Filling Stop-Motions, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

This invention in filling stop motion for looms is illustrated as applied to a lay having a center feeler.

In my invention I have devised a novel dagger it being mounted on a horizontal pivot carried by the lay and standing at right angles to the length of the raceway so that the dagger in operation moves in a vertical plane substantially parallel with the side of the lay, the dagger having a foot that when not supported descends by its own gravity.

In looms as now commonly constructed the shuttle as it is traversing the raceway of the lay frequently strikes the feeler fingers or wires, and to obviate this I have embodied in my invention means whereby the feeler fin- -gers or wires are raised as the lay is being moved backwardly from the breast beam and while the shed is opened, and preparatory to picking the shuttle across the raceway to lay a filling in the 0 en shed.

When the filling fails in a shed the loom is stopped automatically and it is customary to run the lay over without throwing the shuttle until the shed is opened in which the mispick occurred.

In my invention I am enabled to run the loom by power while finding the right shed to correct a mispick. By at such time manipulatingthe shipper handle to turn the main shaft a little at a time, I have combined with my filling stop motion means whereby the dagger that moves the knock-off slide to stop the loom when the filling fails is rendered inoperative while the loom is being actuated to find the shed in which the mispick was made, or in other words I have provided means for lifting the dagger through the shipper handle" when the same is being moved to actuate the loom step-by-step while opening the shed to find a mispick, said means bein rendered inoperative after returning the slipper handle into its holding notch.

Figure 1, in plan view, shows part ofna breast beam and lay, the latter being at its back stroke, the shipper handle being held in itsoperativeposition,the loombeing supposed to be running regularly; Fig. 2 is a section in the line ob, Flg. 1, looking at the inner side of the lay, chiefi to show the novel dagger; Fig. 3 is a view 0 the parts shown in F ig. 1 looking toward the left; Fig. {I is a view looking toward the right, Fig. 1, showing the daggerreleaser lifted as when the loom is being moved to find a mispick; Fig. 5 is a like view showing the lay as having completed its forward stroke, the parts beingin the condition occupied'by them when the 100111 is running regularly.

Referring to the drawing A represents part of any usual breast-beam; A part of the lay provided with a reed A the lay in practice being pivoted in usual manner at its lower end on a cross-shaft. To the underside of the breast-beam L connect by lag screws A, see Fig. l, a stand A having adjusta'bly connected with it by bolts (1. the slotted upper end a of a forwardly extended bar B having at its underside a lug B, said bar having at its left hand side two horizontally-extended lugs a, a

The lug B receives a bolt B that is extended through a slot B of the foot of an adjustable arm B having a guiding lip B, said arm being adjustable to place its beveled part B at just the proper distance from the breast-beam to be struck sooner or later by the heel a of a dagger-releasing device B pivoted at a on the knock-off slide The knock-01f slide is slotted at a near its end next the breast-beam to fit over the lag a and its inner or opposite end is rounded at a to fit a hole in car a.

The slide B has a stop shoulder a that normally contacts with the ear a, and at its upper .side said slide has a notch b.

The loom side at one end of the breastbeam has a connected spring-controlled shipper handle b that is movable in the handleguiding slot b of the usual handle guide plate b having a side notch to be entered by the shipper handle that the latter may be held in locked position, as shown in Fig. 1, when the loom is running regularly and the usual driving means of the loom isclutched or in operative position.

The plate I) has a stud b" on which is pivoted a knock-off lever I) the inner end of which occupies such a position, see Fig. 1, that the side of the shipper handle when in its notch will contact with the inner end of said lever. The outer end of the lever I) has a hole to receive the downturned end of a link 6 connected at its other end with the outer end Z) of an elbow lever having its hub mounted loosely on, a vertical stud b at the lower side of the breast-beam, the i downturned end 6 of said lever acting' against the outer end of the knock-off slide due to the spring (Z, said lever under the normal action of said spring maintaining the knockoff lever Z) in the position shown in Fig. l, and keeping the end a of the knock off slide in contact with the ear a The lay has connected with it by bolts C, a stand C having ears C between which on a stud a is mounted a filling fork head 0 having connected with it by screws 2 a series of fingers 3.

The head 0 has connected'to it at L the upper end of a link 0 jointed at its lower end at 5 with the inner heavier end of a novel dagger C having a long foot 7, and made as a lever mounted on a horizontal stud C projected from an ear C of stand 0. The stand C has connected to it at its lower end at one side by a screw o a daggerlocking device 0 to be described.

Referring now to the right hand side of bar 13, see Figs. 1 and 2, said bar has two like lugs D that receive the slotted parts cl of a dagger-actuating slide-bar D having at its outer side two like projections d, (Z

said bar having at its upper edge a dagger cam D provided with an inclined edge 6. The slide-bar D is provided at its inner side with a roller or other stud 7 that enters a cam slot 8 in an auxiliary dagger controller E the ends of which are guided in the ver tical movement of said controller due to the stud 7 traveling in the slot 8 by vertical shoulders 9 crossing the bar B vertically. The upper edge of the controller E is inclined at 10 near one end.

The stand C, see Fig. 3 has a depending striker D that strikes first one and then the other projection cl or (Z of the slide bar D and slides the same horizontally over the lugs D of the bar B, the striker as the lay is moved away from the breast beam into the full line position striking the projection d and moving the slide bar with it, and at such time the stud 7 in slot 8 lowers the dagger-controller E, as shown in Fig. 3, and as the lay is moved toward the breast-beam said striker meets "the projection d and moves the slide-bar D with it in the same direction and at such time the stud 7 in slot 8 raises the dagger-controller into the posisary when finding the shed in which the mispick occurred that weaving may be resumed in the shed when the fault in filling occurred thus providing for weaving perfect cloth.

It will be understood that the shuttle is not thrown to leave filling while the shed in which the mispick occurred is being found, and it will also be understood that if a filling is not laid in each shed as the lay is moved forwardly the loom would be stopped at every forward beat of the lay so I have provided the dagger-lifter and its actuator that the dagger may be held up and not move the knock-off bar.

The actuator has its end 6 next the lay turned up to meet and lift the dagger-releaser, and its opposite end has an upturned portion 6 provided with a horizontal extension 6* provided at its underside with a looking notch e that may be engaged by a stud a extended from a locking member 6 made as a lever pivoted on a stud 6 carried by an arm 6 connected by a screw 6 with a rod 6 attached at one end to an ear f of the shipper-handle b, the opposite end of said rod at the opposite end of the lay being connected with a short auxiliary shipper handle, not shown, substantially as provided for in United States Patent No. 77361 dated April as, 1868.

The arm 6 that'it may be kept steady in it's movements has a second hole to receive a guide rod f parallel with the underside of the breast-beam. Vhen the shipper handle occupies its position Fig. 1 in its holding the stud 6, see Fig. 1, occupies a position under the extension 6 of the actuator, and at suchtime, the loom running regularly, the said stud enters the notch e and locks the actuator e.- in the position Fig. 5 where it remains so long as the filling is laid regularly in the shed. A final movement is given to the locking member e by the contact with its lower end of a rod 0 suitably connected with a portion of the stand C carried by the lay, the free end of said rod meeting the lower end of the locking member and turning it slightly to place the stud e in the notch e at the first full forward stroke of the lay after the shed in which a mispick was madehas been found and the shipper lever has been put in its holding notch that the'loom may be runby. power and weaving be done. I

The top of the raceway of the lay has a series of cross-slots in which may enter the wires 3 of the feeler whenever said wires,v

the lay being moved forwardly after the flight of a shuttle thrown across the lay, has not left a shot of filling in the shed, said wires entering said notches whenever the descending wires are not arrested by a shot of filling in the shed.

Whenever the filling is laid in the shed .100 notch, the rod 6 occupies such position that the feelers in their descent as the lay is being moved toward the breast beam meet the filling and consequently the foot of the dagger is not permitted to drop far enough to meet the shoulder b of the knock-off slide and the loom continues to run uniformly.

v notch b of the knock-off slide and will push said slide with it toward the breast-beam causing the end of said slide in contact with the end of the elbow-lever to turn said lever, draw on the rod 6 and move the knock-off lever b to cause it to push the shipper handle out of its holding notch, and this movement of the shipper handle will move the rod in a direction to withdraw the stud e from the notch of the arm 6" letting the heavier end of the actuator e drop. The actuator is not however released until after the knock-off slide has been moved sufficiently far to the right, Fig. 5, to cause the heel of the dagger-releaser to meet the incline 6 which will raise the dagger-releaser causing it to contact with the foot of and lift the dagger from engagement with its notch Z).

.Vhen the actuator has been unlocked its end 6 is lifted and contacts with the underside of the dagger-releaser, see Fig. 4, and thereafter said actuator retains the daggerreleaser sufficiently elevated to prevent the dagger from engaging the shoulder b of the knock-off slide during such movements of the lay required to find the mispick, the operator at such time holding the shipper-handle in his hand and moving the same sufficiently to start the loom and move the same slowly step-by-step by clutching the usual driving power, and during this operation the da 'ger cannot move the knock-off slide.

VVhiTe the operator is moving the shipperhandle to and fro in its slot and not carrying the handle into the notch and leaving it there the stud .6 may be carried again under the extension 6" of the actuator and at such time the locking member may stand, as shown in Fig. 4, but said locking member is not turned to cause its stud e to enter the notch e and lock the actuator in the position, Fig. 5, until the shed in which the mispick was made has been found and opened and the shipper handle has been left in its notch and the loom has been started at which time the end 6 of the actuator e occupies its inoperative position with relation to the dagger-releas ing means.

In looms as now commonly constructed the feeler wires at times get into the path of the shuttle being thrown along the raceway through the shed and damage is done both to the loom and to the fabric being woven. To obviate'this I have combined with a loom means whereby the feeler wires are lifted positively as the lay approaches its back stroke and prior to throwing the shuttle through the open shed. The means shown by me for doing this comprise the slide-bar D and the controller E.

In the operation of the loom weaving regularly the dagger is held up by the contact of the wires with the filling and as the lay completes its forward stroke the striker meets the projection (Z and moves the slidebar D from the position Fig. 3 into the position Fig. 5, and at the same time the controller is lifted into the position shown in said figure.

Now as the lay is being moved in its back stroke when the shed is being made and the shuttle is thrown theretln'ough, the dagger contacts with the inclined part 10 of the auxiliary-dagger controller, rides up said incline and gets onto the upper edge thereof and onto the top of the cam D of the slidebar D, and finally as the lay nears its back stroke the striker D meets the projection [P and moves the slide-bar D sufliciently to rause the stud 7 to lower the controller E and carry the top of the cam D under the foot of the dagger, as in Fig. 3, and the dagger sustained by the top of the cam part D of said bar D lifts and holds up the feeler wires, as shown in Fig. 3, and at this time the shuttle is thrown through the open shed, and as the wires are lifted they cannot be struck by the shuttle.

The dagger at the back stroke of the lay stands onthe upper edge of cam D about in the position Fig. 3, so that it may slide practically down the inclined end 6 as the feeler wires descend to feel for a shot of filling.

The dotted lines Fig. 3 show part of the lay as having been started toward the breastbeam and the dagger as having descended the incline (5 until the wires are arrested by the filling, the dagger when the wires rest on the filling not descending far enough to strike the shoulder Z) of the knock-off slide.

During the forward movement of the lay after the wires in the movement of the lav have been carried off the last shot of filling laid in the shed and the warps have been closed on the filling prior to the reed beating the filling in at the shed, the ends of the wires should not scratch over the underside of the cloth being woven, and to guard against this I have provided a detaining or locking device, shown as an arm 7' connected with the stand A by a screw i and extended toward the lay so that as the lay completes its forward stroke the end of said arm meets the underside of the short arm h of the dagger and holds the heavier or foot end thereof down as the lay completes the forward stroke and while being moved for part of its back stroke, the dagger being at such time locked with the wires 3 held so as not to injuriously scratch the fabric, said locking device releasing the dagger prior to raising the latter that the shuttle may be thrown through the open shed.

The foot of the dagger is long enough to cross not only the knock-off slide but also the slide-bar D and the dagger-controller E and the dagger when acting moves in a plane substantially parallel with the inner face of the lay.

Having described my invention what I claim as new and desire to secure by Letters Patent is 1. In a filling stop motion, a lay, a feeler carried thereby, a dagger connected with said feeler, a knock-off bar, a connected dagger-releaser, an actuator, and a member for holding said dagger-releaser in its inoperative position, combined with a shipperhandle, and means controlled thereby to permit said member to occupy a position to hold the dagger-releaser in its inoperative position.

2. In a filling stop motion, a feeler having a connected dagger and a slide-bar having a cam, combined with an auxiliary-feeler controller under the control of said slide-bar, the latter raising the auxiliary-feeler controller and maintaining said feeler lifted while the shuttle is being thrown across the lay, and lowering said feeler-controller after the picking of the shuttle and while the lay is on its back stroke.

3. In a filling stop motion, a shipper handle, a knock-off bar, means actuated by said bar to release the shipper handle, and a feeler carried by the lay and having a con nected dagger, combined with a slide bar having a cam, an auxiliary feeler controller under the control of said slide bar, the latter raising said feeler controller as the lay is moving toward the breast-beam to thus lift the dagger and feeler, and lowering said feeler controller as the lay is next moved backwardly the dagger at such time if the feeler is not sustained by filling on the lay dropping and meeting the knock-off bar to effect the stopping of the loom.

4:. In a filling stop motion, a lay, a feeler, a connected dagger, an arm sustained by the breast beam, a notched knock-off bar sus tained by said arm, a dagger releaser carried by said knock-off bar, and means to move said releaser while the knockoff bar is being moved by the dagger to release the latter from the notch of the knock-01f bar.

5. In a filling stop motion, a lay, a feeler a connected dagger, an arm sustained by the breast beam, a notched knock-off bar sustained by said arm, a dagger releaser carried by said knock-off bar, and an adjustable arm having a beveled portion to sustain said dagger releaser, the dagger releaser as the knock-off bar is moved by the dagger contacting with said beveled portion to raise said releaser to disengage the dagger from the notch of said knock-off bar.

6. In a filling stop motion, a guide-bar to be sustained by the breast-beam, a slide-bar loosely sustained thereby and having two projections at its side and a cam at its upper edge, a dagger-controller, a feeler having a connected dagger, combined with a striker to meet said projections and slide said bar in one and then in an opposite direction, means connecting said slide-bar and dagger-controller to lift the latter as the slide-bar is moved in one direction and insure its descent when the slide-bar is moved in an opposite direction whereby said controller and slidebar acting on the dagger during the backward movement of the lay from the breast-beam effects the raising of the feeler prior to moving the shuttle through the usual shed in the warp.

7. In a filling stop motion, a lay, a feeler and connected dagger carried thereby, and a striker also carried by the lay, combined with a slide-bar having two projections, and means to sustain said slide-bar, said striker meeting one of said projections as the lay is being moved forwardly and the other as the lay is being moved backwardly, and moving the slide-bar first in one and then in an opposite direction and means operated by said slide bar for controlling the position of the feeler.

8. In a filling stop motion for looms, a lay, a feeler pivoted thereon, a dagger made as a lever, a connection between said dagger and feeler, combined with a rod carried by the breast beam to engage the short arm of the dagger andturn the latter and depress the feeler wires and prevent them scratching under the fabric between the breast-beam and the fell of the fabric.

9. In a filling stop motion for looms, a lay, a feeler having a series of wires, a connected dagger, and means to lock said dagger in position during the last half of the movement of the lay toward the breast beam to hold the feeler wires beneath and prevent them from scratching the fabric being woven.

10. In a filling stopmotion for looms, a lay, a feeler to feel for and detect the pres ence or absence of filling in the shed, and. means to lock said feeler beneath the fabric being woven during the latter part of the movement of the lay toward the breast beam.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
