This invention relates to looms and has for its principal object the provision of a simple device for checking the shuttle at the end of its travel so that it comes to rest in exact position and is discharged from such position by a trigger operated spring mechanism the latter cooperating with the binder to release this member just prior to the driving forward of the shuttle.

A further object of the invention lies in the provision of mechanism which constitutes a unit readily attached to the lay beam and adjustable thereon without alteration of such of the mechanism as is retained. By having the mechanism a unit an entirely new mechanism can be applied in about ve minutes as against the period of nearly a half hour where a picker stick must be replaced.

A further object of the present invention lies in the provision of a spring driven picker in which the picker has an elongated guide in order that the blow against the shuttle may be given exactly in the axis of the shuttle and in which the adjustment of the spring, the adjustment of the trigger, the adjustment of the timing, the adjustment of the position of the picker spring housing, the positioning of the bumper and the positioning of the link that holds the free end of the binder are each and every one independently adjustable whereby an alteration of relative arrangement of any one or more of the parts will not affect the adjustment of the other parts thereby saving a very appreciable time.

An important feature of the present invention lies in the provision of a spring pressed picker in which the spring is fully expanded at the time the shuttle enters the shuttle box and is compressed while the shuttle is at rest.

A still further object of the invention lies in the provision of a discharge and checking device which is little aifected by humidity and which is substantially, if not entirely, free of the fault of knocking off. This knocking off or jarring of the clutch so as to stop the machine is the result of accumulative action which is avoided in the present mechanism by having the binding action directly dependent upon the speed of the shuttle.

A particular object of the present invention is to lengthen the life of the various parts and to cut down by an appreciable percent the amount of power requir-ed to drive the loom. These objects are achieved by the elimination of the picker stick and the cam7 the latter causing excessive wear on three of the teeth of the counter shaft gear, that is, the three teeth which are in engagement at the time of the sharp jar when the cam is in discharge position.

Other objects of the present invention will be ascertained by a consideration of the following specification and are particularly set forth in the appended claims.

In practically all previous looms the shuttle is driven by a picker stick which in turn is cam operated. Many attempts have been made, it is true, to drive the shuttle back and forth by magnetic or spring action but as far as I know these devices have not gone into commercial production due in many cases to some very obvious and outstanding disadvantage, for example, in most of the spring discharge shuttle mechanisms either the shuttle will not come to rest in precise position so as to discharge the old bobbin and receive a new one but in fact some of the proposed devices are so arranged that the bobbin must enter and leave at the side of the shuttle and there is no mechanism on the market that can have this action. It is old to use a leather faced binder to check the motion of the shuttle and to hold the shuttle rmly in desired position until it comes to rest and then later to release the pressure on the binder but in none of these devices is such action associated with a spring discharge mechanism. In the present device I have a reciprocating cam to the follower of which a trigger is attached and to the trigger in turn is connected the binder link so that these parts are associated together in correct relationship altho I preserve independent adjustment of all the several parts. The cost of the new mechanisms described herein is appreciably less than half of the cost of the parts which are dispensed with but this is not the principal advantage for the saving in time, which is much more important, is very marked as the same mechanism can be adjusted to discharge and receive light or heavy shuttles and can operate with a shuttle of any of the lengths ordinarily used.

In the drawings:

Figures 11 to 15 are sections taken on lines shown in Fig. 6 bearing similar numerals.

Figures 16 and 17 are details illustrating the modified form of toggle.

My device is intended for application to already existing looms as no change is required in the modern loom save the replacement of the usual picker stick mechanism by my present gun which forms with the ordinary binder and the bottom of the lay beam together with the optional cover, not shown in any of the figures, a shuttle box. Inasmuch as the loom itself 'has nothing to do with the present invention the drawings illustrate the loom in a diagrammatic manner only, Il) being the frame, l l the crank shaft which, of course, is the usualmain drive shaft receiving its power thru a pulley from the line shaft if such be used or from the individual electric motor as is becoming very common. The cranks I are pivotally connected to the pitman i5 .which is joined as at Il to the so-called sword I8 pivoted on the transverse rock shaft 26. At their upper ends the two lay swords IB carry the lay beam 23 which may be entirely of wood but more frequently has metal ends. My device will work equally well with either. At the rear of the lay beam 23 is the reed 25 and the binder 26. 'Ihe dagger rod mechanism indicated generally by the numeral 21 is of ordinary form and serves to throw out the clutch when the lay beam reaches one end of its stroke Without the shuttle being in place in the shuttle box. All of the portions so far are old and well known and I make no claim whatsoever to them save in combination with the new elements which will now be described.

Having particular reference to Figure 4 the binder 26 which moves about its xed pivot 29' forms the rear side of the shuttle box the front guide portion of which is a smooth piece 30 of hardened steel which may be, if desired, and preferably is, integral with the angle bracket 3| which holds the gun on the lay beam 23. As shown in Figure 3 the downwardly projecting plate 32 of the angle bracket 3l is provided with slots V32a to accommodate the lag screws 32h' construction permits the adjustable mounting already mentioned. The shuttle 33 in Figures 4 and 6 is at the end of its travel in one direction and rests against the picker 35 which latter, as Will be seen from the sectional view, is a steel cup containing resilient material 35 preferably a ycoiled strip of leather. The buffer bumper 38 to the rear of the picker is preferably also a cup-like member also containing a filling such as 39 of leather, likewise for cushioning purposes.

The trigger 'l'is connected to the bumper 38 by a rod lll and a lever 43 pivoted to the gun housing as at 5 is also secured to the trigger 'I at one end and slidably receives at its other' end a link 46 pivoted as at 47 to the free end of the binder and passing thru a slot 48 in the centrally pivoted lever 43. Adjustment is provided by means of the lock nuts 49.

Referring now particularly to Figure 6 the barrel 56 of the gun for economic reasons is preferably manufactured from a rather high grade of tubing which can be purchased commercially so smooth as to require no grinding or polishing. This barrel or tube 50 is permanently secured to the guide 36 and/or bracket 3l as by welding or brazing and has its inner end, which is a disk 5i, permanently secured to the barrel or tube 50 but I prefer that the other end, the disk or washer 52, shall be replaceably secured in position. This I accomplish by threading the -rod 55 into the permanently secured end 5| and by binding the closure disk 52 in place as by the nut 56. The removable disk 52 is of two diameters the lesser diameter fitting very snugly Within the bore of the barrel or tube 50 as I desire that this rod 55 shall be exactly coaxial with the tube. The picker sleeve 51 fits rather snugly within the barrel 50 and has an elongated bearing surface which insures that its travel shall be in a line precisely parallel to the axis of the shuttle. The inner bore 58 of the picker sleeve 5'! extends thruout the length of the sleeve except at the ini ner end of which there is an inwardly directed lip 59 serving as a shoulder for the one or more springs 66 which drive the shuttle thru the picker.

Slidably engaging the opening in the annular. lip 59 is a spring compressor sleeve 62 permanently and preferably integrally secured to the spring compressor base 63 from which extends the bracket 64, the latter sliding in a slot 65 in the barrel 56 and also in slotr 66 in the picker sleeve 5l.

The trigger 'i6 is a flat sheetof metal carrying integrally at its forward end a vertically disposed sleeve il which pivotally receives the downturned end 13 of the link ll which is fast'to the bumper bracket l5 in which is adjustably mounted the bumper 38 the correct positioning being secured by means of the lock nuts I6. This bumper bracket has an inwardly extending guiding surface i7 which slides a short distance along theV hardened steel guide plate 3|). I also prefer that the bumper bracket be held to the gun barrel 5U by some resilient means as for example, the spring i9 having just suiicient tension to hold the bumper bracket guide against the mainguide.

In the vertical bearing 'il of the trigger below the bottom of the downturned endY 13 issvveated or otherwise secured a stud shaft 80 on which is rotatably mounted the roller 8| which is the cam follower. It will be noted that this cam follower 66 is directly connected to the trigger 10 and consequently to the Vpivoted lever 43 which in turn is permanently secured to the triggerV while the link M is not permanently secured but merely has a pivotal connection the intention being that the bumper and its bracket and the link ii can readily be lifted oif of the gun barrel without disturbing any other part, the downturned 'end 'f3 Vbeing slidable in the trigger bearing.

Adjustably mounted in the bracket 64 lof the spring compressor is a short section85 of rod permanently secured to the cable 36 which extends inwardly toward the relatively large guide pulley 6i carried in a pair of depending ears 92 preferably integral with the Vgun barrel 56 and then downward, as seen in Figure 3, to the idle pulley 95 (Figure 2) loosely mounted on the rock shaft 2Q, thence upwardly and rearwardly to its oted as at Sl to the gear 68 on the countershaft :99 which is a transverse shaft parallel to the `main drive shaft which is the crank shaft.

The pinion fast on the end of the main drive or crank shaft meshes with the gear 98 and drives the countershaft 99 at half speed. The countershaft 99 at its distant end, as seen in vFigure 2, carries a crank |02 pivoted to a tube |03 exactly similar to the tube 96 and connected to the opposite shuttle mechanism.

The cam |05 is adjustably secured on rod 85 so that this cam which governs the discharge of Yshown in Figure 1G in which the toggle barrel |07 is an integral extension on the gun barrel having a smooth bore therethru in one end of which is threaded the adjusting screw |08 and in the far smooth portion of the bore a small cupped cylindrical slide |09 is held in contact vwith the connecting pin which rests in an indentation in the body of the trigger 10. Since each of the two ends of this connecting pin l Hl is in a cup-like cavity and since the plunger slide |09 is constantly urged outward by the spring ||2 it is always held in place altho not fastened. Upon first movement of the cam surface |06 against the roller or follower 8| the action is solely to release the toggle mechanism of Figure l0 in order that the binder can be free, The toggle has important action just beyond the position in which the binder is free, namely, as

the trigger starts to move forwardly by the cam action the toggle snaps it quickly into extreme release position entirely freeing the sleeve 5l of the picker. The active end of the trigger is recessed as at ||4 so as to clear at all times the sleeve of the spring compressor.

In Figures 16 and 17 is shown a modified and very satisfactory form of toggle mechanism, this being merely a single piece of wire having a central bight and passing at one end thru a hole H8 in the trigger 'lila and passing at its other end thru a hole i9 in a bracket |20 which is brazed or otherwise secured to the barrel 50 of the gun for that purpose. In spite of the extreme simplicity of this modified spring it serves the purpose remarkably well and except for the adjustment of the mechanism shown in Figure the spring i gives the same action.

The operation of the device is as follows, be-

i ginning with the lay beam in its forward position Iso and the shuttle at the right hand end of its travel. The positions of the parts are as shown in Figures 4 and 6 and the reed has just beaten the last thread against the cloth. The drive shaft is revolving in counterclockwise direction as seen in Figure 2 and the pin 91 on the half time gear 98 has just passed dead center. As the drive shaft turns, the countershaft 9S is revolving in clockwise direction and the lay beam is moving rearwardly, that is, toward the warped threads. The cable 9B is now taut and is compressing the spring 66. The cam 4&5 is consequently advancing inwardly toward the cam roller 8| but no other action is taking place. Asv the beam reaches almost its mid-position in its rearward oscillation the cam strikes the roller and causes the trigger 10 to move forward a slight amount but not enough to free the plunger. This movement, however, does accomplish an important mission, it turns the lever 43 about its pivot 45 and frees the link @6 which is secured to the free end of the binder which latter is therefore free to turn about its pivot G7 and therefore offers no appreciable friction to the shuttle.

An extremely slight further movement of the drive shaft brings the lay beam into line with the center of the shed and at this moment the cam releases the trigger 1|) which under the urge of the toggle spring ||2 or snaps the trigger rapidly to release position, freeing the picker sleeve or plunger and discharging the shuttle with a powerful throw which it will be noted is in direct line with the axis of the shuttle.

Instantly after the shuttle has been discharged the parts are in the positions shown in Figures 5 and 8. No bumper at this end is needed for the plunger and the picker which is carried thereby because the plunger spring is secured relatively permanently to the two sleeves, that is, the plunger sleeve and the spring compressor sleeve. The picker is consequently spring held against forward and backward movement. At this time the bumper bracket which adjustably carries the bumper has slid along the smooth face of the shuttle guide 33 to the inward end of its movement which, however, is very slight. The relatively light spring SS is acting at this time to keep the slack out of the cable and the bumper bracket spring 'i9 holds the bumper bracket firmly against the face of the guide. It might be remarked here that the principal function of this spring is to prevent noise and to obviate backlash. The spring is so constructed as to render convenient the lifting off of the unit consisting of the trigger di), the lever 43 and the link 4|, the latter carrying the bumper and its bracket.

Still further movement of the drive shaft carries the lay beam to its extreme rear position without any change in the mechanism of the shuttle actuating device. Upon forward movement of the lay beam the spring 68 causes the return of the shuttle compressor sleeve 62 and this latter carries with it the plunger or picker sleeve 51 because the spring 6|) is so much stronger than the spring 68. The cam |05 is also moving outwardly or toward the end of the lay beam under the urge of the spring 68 and this movement of the parts within the barrel 50 continues until the lay beam is again at its extreme forward position. At this time the lay beam starts its return or rearward movement, the shuttle box at the right being still empty. At such time as the lay beam is approaching central position the pulling on the cable is entirely reieased and the spring 68 has returned all of the parts almost to initial position.

The binder, however, is still loose and the bumper while in engagement with the picker rear is not at the outward limit of its travel nor is the trigger in holding position, on the contrary being held outward to the full limit of the trigger travel by the toggle link lill. The parts are in exactly this position as the shuttle moves from the free end toward the end Linder consideration. The shuttle enters the shuttle box being guided, if necessary, by the somewhat beveled inner end |2| of the shuttle guide plate 3E) and passes freely into the shuttle box until the flat side of the shuttle engages the leather face of the binder, this engagement being possible by the presence of the usual spring between the rear face of the binder and the dagger rod clip. A slight friction is therefore exerted on the shuttle as it moves toward the end of its stroke.

As the pointed end of the shuttle strikes the counter-sunk leather 35 in the pocker 34 it causes a rearward movement of the picker and the bumper 38 which at this time is in contact with it. This engagement moves the plunger 57 outward just sufciently to clear the trigger l!) which because of the rearward movement of the bumper bracket l5 and the pivotal engagement of the link di with the trigger, turns the lever 43 sharply about its pivot under the snap action of the toggle, snapping the trigger into closed or retaining position and simultaneously snapping the binder against the shuttle with a pressure dependent upon the speed of the shuttle. The shuttle therefore is held in a viselike grip and remains stationary at the end of its travel without rebound. This completes the cycle which is repeated as before.

It will be noted that the entire gun device is a single unit which may be secured to the lay beam by the usual two guide screws 32h shown in Fig. 3 and upon removal of these two screws the entire device can be released as a unit since the downturned end el of the link i6 is loosely received in the leather loop 23 which lies between the dagger rod clip and the free end of the binder. For extreme convenience of dismantling the unit I prefer to unasten the connection between the cable and the crank tube 9&5 or m3 on the countershait 99 but where time is not so important I prefer to retain the cable on the loom and to disconnect the cam and the lock nuts which secure the cable to the spring compressor bracket 6ft. These lock nuts just mentioned provide for the proper tension on the spring and provide a heavier or lighter throw. It will be noted that this adjustment is entirely independent of the adjustment of the cam on the cable and consequently a tightening or a loosening of the spring tension will not alter the timing which is controlled by the position of the cam alone because the crank pin 97 is arranged on the half time gear in correct position and is not sensitive as to time as is the cam of the usual picker stick action. The wear on the teeth is substantially uniform because of the smooth action of the device whereas in the cam operated picker stick the wear is concentrated on three of the teeth.
