FILLING-CARRIER RECEIVER REPLENTISHJING-LQOMS.

. Application fi1ed.Febrnary 12, 1926. Serial No. 87,779.

This invention relates to. filling carrier receivers for catching thefilling carriers as they are ejected from the. loom upon replenishment of filling.

It is now the common practice to provide filling replenishing looms with a receiver or can into which the filling carriers. are thrown upon replenishment of filling. It sometimes happens. that a'filling carrier is. ejected from a shuttle while still. containing a working supply of filling, and inv such case the filling carrier may be returned to the hopper to be again used in the loom.

In weaving fabrics with certain kinds of filling, the impact of the ejected filling carrier against other-filling carriers already in the can or receiver, frequently injures. the filling on the ejected filling carrier tosuch an extent that even if the carrier contains. a working supply of filling, it may not be practical to return the filling carrier to the hopper and weave in the injured filling.

This is particularly observable in connection with fine filling, such, for instance, as

silk, artificial silk and the like, and one of; the objects of the present invention is to provide a filling carrier receiver which will avoid injury to the filling on a filling carrier when it is ejected from the loom, so that should the filling carrier contain a working supply of filling, it may be returned to the hopper and the filling thereon be subsequently, woven into the cloth.

The invention and novel featuresand new con'ibination of parts will best be made clear from the following description and the ac-:

companying drawings of one good form thereof.

In the drawings Fig; l is a, perspective View at the replenishing side of a filling replenishing loom, showing a; filling carrier receiver 01" can into which the ejected filling carriers are thrown from timeto time; 7

Fig. 2 is an enlarged detail perspective View showing the filling carrier receiver provided with the present invention: and,

Fig. 3 is a vertical. section of a filling carrier receiver containing the present invention.

The loom frame- 1 may be of usual construction and have mounted thereon a, hopper 2 containing filling carriers 3 containing filling for use. in a shuttle, and such hopper and. its associated parts may be of any usual character.

,The lay 4 is pr0vided, wit,h the usual shuttle box at the filling replenishing. Side of theloom for the reception, of. the shuttle 5, and mounted on the loom frame or a bracket secured thereto isthe usual transferring mechanism for transferring the filling carrier. from, the hopper to the shuttle,

and simultaneously ejecting the fillingcarrie* previously in the shuttle. The transferring mechanism may comprise the usual transferrer' 6 having the downwardly ex tending arm 7 to which is pivotally mounted the dog; 8 adapted to be engaged by a hunter 9 on the; lay to effect the transfer] These parts may be as usual. 7 V

The shuttle '5 may also be of the usual filling replenishing type, and it, as well as the bottom. of the shuttle box, may also, as:

usual, he provided with. an opening through which the ejected filling carrier may pass downwardly into the filling carrier receiver bcneath.,1t may be desirable at times to employ a chute 10 down which the ejected filling carrier may be guided. on its way to the receiver, i

The present invention. is more especially directed to: thefilling carrier receiver, which is located at the replenishing sidepf the loom in position to. receive thefilling carriers.

as they are ejected fromthe shuttle.;.

The carrier receiver comprises. a

receptacle 11, the frontwall 12 of which is.

higher than "the backwall 13,.- and'. the two walls are connected by the sideplates-lt and by the bottom plate, 15. The front wall 12 is carried upwardly'beyond. the. top of the side walls to provide a hand-grip 16, and such receptacle or receiver as thus far describedmay beef usual construction.

When a. filling carrier, is ejected from. the shuttle during replenishment of filling, it is thrown. forcefully in a downward direction through the chute 10 into the receiver or can beneath, and should at such times the filling carrier contain ajworkingsupply of filling; such filling is liable to. be injured by impact,

against other filling carriers already in the Eeceiver, or, indeed, against any hard surace.

In accordance with the present invention, the filling carrier receiver is provided with a flexible apron preferably located near the lower part and within the receiver to divide it into an upper and lower compartment and the apron is so mounted in the receiver that upon impact of a filling carrier upon the apron, it will flex and ofier a yielding surface contact with the filling on the filling carrier or bobbin. i

The flexible receiving apron 17 may be formed of a suitable fabric, such, for instance, as canvas or the like, and the front end portion of the apron 17 is secured in the receiver adjacent the front wall thereof, while the rear end portion of the receiving apron is yieldingly held in the receiver nearer the back Wall thereof.

In the present instance of the invention, the filling carrier receiver has extending between the sides 14 thereof a bar or rod-18 which serves as a means for securing the of the receiver. Extending between the sides 14 of the receiver is another support which may be conveniently constituted as a bar or red 19 over which the body portion of the flexible receiving apron 17 passes and upon which it rests. The free end of the flexible receiving apron is under the influence of means for yieldingly maintaining the apron in its carrier receiving position such that upon impact of a filling carrier thereon, the apron may flex, as indicated by dotted lines in Fig. 3. As means for thus maintaining the apron in the position de scribed for the performance of its flexing function, a down-hanging portion 20 of the apron may be connected to a weight 21 secured to the lower end of the apron, the construction being such that when the filling carrier strikes the apron 17, the weight 21 or other yielding holding means, will permit the apron to flex by drawing over the supporting rod or bar 19, substantially into the dotted'line position indicated in Fig. 3, and

where a weight is used for this purpose, the.

weight will be adapted to yield upwardly on the impact of a filling carrier against the flexible apron, to thereby permit the flexible apron to draw or move over the supporting bar or rod 19. V

The supportingbar 18 for securing one end of the apron in the receiver is preferably located higher up in the receiver than the supporting bar or rod 19, with the re sult that after a filling carrier has been received by the apron, and it. has flexed, the filling carrier, which may still contain a working supply of filling, will roll down carrier from'injury' at such times, the pres-;

ent invention contemplates the provision of a curtain or apron extending upwardly in the receiver from a point ad acent the fiex ible receiving apron against which the ejected filling carrier may strike with non-injurious contact of the filling.

The curtain or apron extending from the receiving apron'may be constituted as a piece of fabric, such as canvas or the like, and may be attached to the receiver at the upper front portion thereof. In. the present instance, the curtain or apron 22 is secured at its upper end upon a bar 23, which extends between the sides 14 of the receiver, flexible receiving apron near the front wall and its lower .end may, in some instances, be secured .to the bar 18 with sufficient looseness, as by a loop asshown to permit the curtain to bend, the construction being such that should a filling carrier strike the curtain or apron 22 when it is ejected from the shuttle, it will cause the curtain or apron to flex, as indicated by dotted lines in Fig. 3, and the filling carrier will then drop upon the receiving apron 17.

The receiving apron 17 and the curtain or apron 22 thus afford a yielding or flexing contact surface against which a filling car rier may impact when it is forcefully ejected. from the shuttle, thereby avoiding any injury to the delicate filling on the carrier and fitting it for use subsequently in the loom should it contain a working supply.

In the particular form of the invention shown, the curtain or apron 22 and the flexible receiving apron 17 are formed of a single piece of fabric, and the upper end of the curtain or apron 22 is provided with a loop 2a through which the upper support-- ing or securing bar 23 may pass to hold the upper end of the curtain or apron at the upper end of the receiver. In order to maintain the flexible receiving apron 17 secured to the support 18,-when the two aprons are formed in a single piece as indicated, the combined aprons may have secured thereto adjacent the support or bar 18, a loop forming piece 25 through which the support or bar 18 may be passed.

The particular construction herein shown and described as an embodiment of the present invention isfound to be practical and effective in preserving from injury the deliwardly 01f from the apron into the lower rate filling remaining on the filling carrier part of the can beneath, and at such times,

or bobbin when it is forcefully ejected from the shuttle, but it isto. be understood that variations may be made in the; arrangement and disposition of the twoaprons, the essentials in these respects being thatthe flexible receiving apron may be secured at one end. within. the receiver and have its otherend. under" the influence of means to yieldin'gly' hold the apron in its carrier receiving position and to flex under impact of th incoming carrier, and that the curtain or apron 22 may be so secured or held within the receiver as to cushion the impact and flex when a filling carrier is forcefully thrown irontwa-rdly against it.

In order to conveniently remove the filling carriers from the lower compartment or" the receiver, a door 26 may be made in the front wall of the receiver.
