ALONZO E. RHOADES, OE HOPEDALE, MASSACHUSETTS, ASSIGNOR TO DRAPER CORPO- RATION, GF HOPEDALE, MASSACHUSETTS, A CORPORATION OF MAINE FILLING-END-BETAINIITG MEANS FOR WEFT-RELENISHING LOOMS.

To all whom it may concern:

Be it known that I, Alonzo E. Rnoaons, a citizen of the United States, residing at Hopedalc, county of Worcester, State of Massachusetts, have invented an Improvement in Filling-End-Retaining Means for W efoBerd'enishing Looms, of which the following description, in connection with the accompanying drawing, is a specificat on, like characters on the drawing representing like parts. r

Thisinvention relates to weft replenishing looms particularly of the automatlc type and its object is to provide means for catch-- ng and thus retaining the trailing end of the vabandoned filling carrier after it is disqcharged from the shuttle in the operation -ofz'replenishment so that it Wlll' not be i ceught and carried by the shuttle or the fresh-filling carrier into the cloth upon the "succeeding pick This object is secured'in the present invention by providing means for clamping the trailing end against the usualchute which guides the filling carrier untiljit is withdrawnfrom the sh Little by the flight of the shuttle.

will appear more fully from the accompany;

ing description and drawings and will be particularl" pointed out 1n the cla ms. i

In the drawings,

box 6 and the lay and shuttle box are provided with a vertical opening 7 therethrough to permit the downward discharge of the abandoned filling carrier when the shuttle is boxed at the transfer end of the loom.

A transferrer 8 is pivotally mounted on the hopper stand on a stud or shaft 9 projecting laterally therefrom. Upon the call for filling replenishment the usual controller shaft or starter rod 10 extending across the front of the loom is rocked and through mechanism not necessary here to describe or illustrate, because well known and familiar to those skilled in the art, the transferrer 8 is swung downwardly to force a fresh filling carrier, in this case a bobbin, from the hopper 3into the shuttle 11 theh bored at the transfer end of the loom and thereby to discharge the abandoned or exhausted filling carrier or bobbin in the shuttle down through the opening 7.

The end of the filling extending-from the abandoned filling carrier throu h the eye-of the shuttle is usually, in ieeler looms, severed by suitable mechanism adjacent the nose of the shuttle and this severed end I and out through the eye of the shuttle and clear of the shuttle or it is liable to be caught by the shuttle or :by the fresh filling carrier and dragged back into the shed and woven into the cloth thus causing an imperfection. g

This invention providesa simple and effective means to catch and retainthis filling end when thc fillingcarrier is discharged from the shuttle and prevent it from being loom, by a metal plate forming. a chute.

Such a chute 12 is shown mounted on a rod 13' pro ecting laterally from a bracket 14: secured to the loom side 1. This chute is in clined: rearwardly and "when the lay beatsup to bring the shuttle box beneath the hopper the upper edge of the chute will be at the rearward edge of the openin 7 so that as the discharged filling carrier, alls it will be guided by this inclined chute into the In this invention means are vprovided which, immediately after the discharge of the abandoned filling "carrier, act to clamp secured thereto a depending tail 23.

the end trailing from. the abandoned filling carrier against the face of the chute so that as the shuttle takes its flight the trailing end is pulled out through the eye of the shuttle and clear the shuttle.

as set into the portion'lG. Preferably also the face of the chute 12 cooperating with the clamping edge of the clamping member is grooved at 18 so that when the clamping action takes place the leather strip 17 swings into the groove 18.

The clamping memberis provided with means which normally not to more itinto clamping engagement with the chute. For this purpose the arm 15 of, the clamping member is shown as journaled on the rod 1?; between two collars l9 and 20. The collar l9 is recessed and in this recess is mounted a helical spring 31. one end of which secured to the collar 19 and the other to the arm 15. A set screw 22 ciiables the tension of this spring to be adjusted by a rotary adjustment of the collar 19. Means are provided to hold the clamping member withdrawn from. the chute. For this pin pose a hook shaped latch 23 is secured to a rod jonrnaled in a laterally extending hub 26 formed on an arm 27 c0nvenienil mounted on an extended portion. of the trausferrer shaft 9. This rod 25 carries at it opposite end adjusiably The hub 26 is recessed and in this recess is mounted a helical spring 21 one end of which is secured to the hub and the opposite end to the latch 23. and this spring acts norn'ially to depress the latch. The clamping member 15 atits upper edge opposite the latch is provided with a catch 30 cooperating with the latch. lieuce when the clamping member 153 is swung forwardly the latch 23 rides over the catch 30 and holds the clamping member in forward position as shown in Fig. 52.

The clamping member .1 is swung forwardly into \i-iigagenieut with the latch through means operated by the lay and thus the clamping member moved away from the chute prior to the discharge of the filling carrier upon the beat up of the lay to bring the shuttle beneath the hopper when replenishment is to take place. For this purpose the clamping member 15 is preferably pro.- vided with a hunter 51 projecting rearass-tees wa'rdly therefrom and preferably made in two-parts and longitudinally adjustable by means of the clamping screw This hunter extends into the path of the lay so as ing mechanism upon the cal-l for weft replenishment or 'prior to weft replenishment taklng place. This may conveniently he done by the construction illustrated in which an arm 33 is adjustably mounted on the end of the controller shaft or starter rod 10. and PIOJBCtS rearwardlybeneath the tail'28 of the latch.

The downward increment of the latch may be limited by an abutment 34 thereon contacting with a stop 35 on the arm 27.

The, operation of the mechanism will now be apparent. The parts during the normal operation of the loom are in the position indicated in Fig. 2. hen the filling in the running shuttle'has become substantially exhausted and weft replenishmnet is to take place the starter rod 10 is rocked through the operation of any of the well known mechanisms provided for that purpose.

This operation raises the arm- 33 which strikes the tail "2S and raises and holds the latch 9.3 elevated thus releasing the clamping member 15 which at once swings rearwardly into clamping engagement with the chute 12, bringing the clamping member into The lay 5 now heats up to bring the shuttle into position beneath the transferrcr. As the lay heats up it strikes the hunter 31 swinging the clamping member forwardly, the operation of transfer takes place during which the fresh filling carrier is pushed into the shuttle and in turn pushes the substantially exhausted filling carrier down through the opening 7 and the abandoned filling carrier falls down the chute 12 and behind the clamping member now in its forward position leaving its end trailing from the shuttle eye down over the face of the chute. The lay now starts on its rearward movement and as it does so the clamping member swings rearwardly and comes into clamping engagementwith the chute thus pinching or clamp- 4 ing the end trailing from the abandoned filling carrier between the edge, in thiscasef, the leather strip 17 of the clamping member, and the chute, in this case the groove 18, of the chute. The shuttle now takes itsfiight and as it does so the trailing end of the abandoned filling carrier being held pinched 'the position shown in dotted lines in Fig 2.

by the clamping member and the chute is drawn out through the eye of the shuttle and thus all danger of the trailing end being caught by the shuttle or by the fresh filling carrier and carried or thrown back into the shed is removed.

Upon the next succeeding beat up of the lay the arm 33 has dropped to its lower position and the lay striking the hunter 31 will swing the clamping member 15 forwardly until it is caught by the latch. --Hence the clamping member will again resume and remain in its locked position until replenish-' ment is again to take place.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a weft replenishing loom, a lay pr'ovidcd with a shuttle box and having an openiag therethrough to permit the discharge of the abandoned filling carrier, a chute mounted on the loom frame and acting to guide the filling carrier in its discharge, a movable clamping member cooperating with the chute, and means acting to cause the said clamping member to clamp the filling end, extending from the filling carrier discharged down said chute, against the chute and to hold said end until withdrawn from the shuttle by its flight.

, 2.111 a weft replenishing 100m the construction defined in claim 1 in which the chute is provided with a groove and the clamping member with an edgefitting in the said groove when the clamping action takes place.

3. In a weft replenishing loom the construction defined in claim 1 in which the chute is provided with a groove and the clamping member with a strip of leather fitting into said groove when the clamping action takes place.

'l. In a weft replenishing loom-the coir struetion defined in claim 1 together with means for preventing the operation of the clamping member during the normal oper atirn of the loom.

5. In a weft replenishing loom, a lay provided with a shuttle box and having an opening therethrough to permit the discharge of the abandoned filling carrier, a

discharge of the filling carrier, whereby upon the backward movement of the lay the clamping member moves into engagement with the chute clamping the filling end extending from the discharged filling carrier and causing said end to be withdrawn from the shuttle in its flight.

6. In a weft replenishing loom, a lay provided with a shuttle bO'X and having an opening therethrough to permit the discharge. of the abandoned filling carrier, a chute mounted on the loom frame and acting to guide the filling carrier in'its discharge, a clamping member, means acting normally to move said clamping member into clamping engagement with said chute, a pivotally mounted latch acting to swing into engagement with and hold said clamping member withdrawn fromsaid chute, means operated. by or through the weft replenishing mechanism to release said latch -prior to weft replenis lnnent taking place,

and maintain said latch released during weft replenishment, and a hunter projecting from said clamping member into the path of the lay whereby upon the beat up of the lay prior to replenishment the clamping member is moved and held away from the 'chu'te during the discharge of the abandoned filling carrier and whereby upon the suct-eedmg backward movement of the'lay the clamping member moves into engagement with the chute clamping the fillingend extending from the discharged filling carrier and causing said end to be withdrawn from the shuttle in its flight.

In testimony whereof, I have signed my name to this specification.
