AUTOMATIC FILLING-REPLENISHING LOOlVL Specification of Letters Patent.

Patented Mar. 6, 1917.

To all whom it may concern:

Be it known that I, UBALD HEBERT, a citizen of the United States, and resident of Manchester, county of Hillsborough, State of New Hampshire, have invented an Improvement in Automatic Filling-Replenishing Looms, of which the following description, in connectionwith the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to improvements in filling replenishing looms in which a supply of filling carriers is maintained in a hopper from which the filling carriers are transferred successively to the running shuttle by a suitable transferrer, and one object of the invention is to provide means to secure the proper position of the filling carrier during transfer in order that it may be directed into the shuttle in proper position.

The invention in its more specific form relates to a filling replenishing loom of the well known Northrop type in which an intermittently rotatable hopper is employed carrying a series of filling carriers about its periphery.

More particularly the invention relates to filling replenishing looms making use of filling carriers having feeling slots in the barrel thereof such as are illustrated for example in the patents to WVilliam Parker Straw No. 906,718 granted December 15, 1908, No. 1,053,673, granted February 18,1913, and No. 1,092,959 granted April 1 1, 1914. When this type of filling carrier is employed it is necessary that the slot therein shall be positioned in a definite relation to the feeler in order that the latter may work properly. Consequently the butts of the filling carriers are provided with suitable positioning 7 means, usually slabbed or flattened surfaces generally in planes at right angles to the longitudinal planes of the slot, and these surfaces are engaged by suitable jaws within the shuttle to retain the'filling carriers in position. The filling carriers are carried improper position. As a result the feeler fails to operate or a smash is caused.

Heretofore it has been proposed as in the patent to Alonzo E. Rhoades No. 1,167,863 granted January 4, 1916 to provide a vertically movable device which shall seize the positioning faces of the filling carrier and move down with the filling carriermaintaining it in position until it is forced into theshuttle.

In, my application 107 ,247 filed concurrently herewith .I have disclosed an invention subordinate to that of my prior application wherein as one of the chief features of the invention the guiding means is pivotally mounted and wherein also in the preferred form the guiding surfaces or elements are inclined to cooperate with inclined filling carrier seats in the hopper.

The present invention is in its main fea tures subordinate to my prior application herewith. In the present invention the gu1d1ng means moves rearwardly and for-.

wardly in a rectilinear direction as in my first mentioned application and is provided with inclinedguiding surfaces as in my second aforesaid application. In this invention the guiding means instead of being moved rearwardly by a connection to the transferrer is moved rearwardly by the action of the filling carrier as it is thrust by the transferrer from the hopper into the shuttle, the forward movement taking place under the action of a spring.

Other features of the invention will more fully appear from the following description and the accompanying drawings and will be pointed out in the annexed claims.

In the drawings,

Fig. 2 is a sectional view of the hopper stand showing in plan the guiding means forming the subject matter of this invention.

. The general construction of the loom may be and is that of the well known Northrop type of filling replenishing loom and needs no extended description. It includes a r0- tatable battery feeder or hopper comprising parallel disks between which filling carriers such as bobbins are mounted in a circular series.

One of these disks 1 is illustrated herein as having a peripheral series 2 of bobbin seats provided with parallel walls 3 adapted to engage the slabbed positioning faces upon the butts of the bobbins. The hopper is rotatably mounted upon a shaft or stud 4 rigidly secured to a hopper stand 5 having a laterally extending bracket 6 by which it is secured to the loom frame. Said bracket has an extension 6* to which is secured an abutment 7 having grooves adapted to engage the rings upon the bobbin and to direct the bobbin in its transfer from the hopper to the shuttle.

A circular flange 8 on the hopper stand surrounding the disk 1 serves to protect the butts of the bobbins until they reach substantially transfer position at which point the flange is interrupted and a pivoted bobbin support 9 provided which holds yieldably the bobbin against the abutment 7 during its transfer.

The mechanism for effecting transfer is of a well known type comprising a transfer arm 10 pivotally mounted upon a stud 11 extending from the hopper stand and provided with a downwardly extending arm 12 through which it is actuated upon a. call for filling replenishment. The opposite or free end of the transfer arm is provided with a curved head or hammer 18 adapted to engage the base of the bobbin and thrust it from the hopper into the shuttle. The transferrer is normally retained in elevated position by a spring 14 anchored to the stud 11 and extending beneath the arm 10.

The hopper is rotated to bring the bobbins successively into a transferring position by means of a dog 15 pivotally mounted upon a stud on the transfer arm 10, the dog 15 having a tooth 16 in operative engagement with teeth 17 upon a circular ratchet secured to or integral with the disk 1. Reverse rotation of the hopper is prevented by a eounterweighted pawl 18 adapted to engage the teeth 17 of the ratchet.

In the operation of the device the transfer arm 10 is forced downwardly by the usual bunter mechanism on the lay causing the head 13 to strike the base of the bobbin and thrust it forcibly from the hopper into the shuttle. During the downward movement of the transfer arm the tooth 16 of the dog 15 falls beneath the next succeeding tooth upon the ratchet 17 and upon the elevation of the transfer arm 10 causes, through the ratchet 17, the rotation of the hopper one step to place the next bobbin in transfer position By reason. of the fact that the butt of the bobbin is held by the bobbin support 9 in rolling contact with the abutment 7 as transfertakes place the force applied by the transferrer to the butt of the bobbin has a tendency to rotate it so that during its passage from the hopper to the shuttle it may become improperly positioned.

The present invention comprises the introduction between the hopper and shuttle of a guide or conveyer normally held in communicative relation to the bobbin seat of the hopper which is in transferring position but adapted upon transfer to be moved rearwardly into registry with the shuttle by the movement of the filling carrier under the influence of the thrust of the transferrer.

The bobbin 20, for the transfer of which the present invention is designed, is provided with a feeling slot in its barrel a short distance from its base. The butt of the bobbin is slabbed to form parallel positioning faces 22 adapted to be engaged by guides in the shuttle to retain the feeling slot in proper position to receive the feeler upon substantial exhaustion of filling.

The walls of the peripheral bobbin seats in the hopper engage the positioning faces on the bobbins and retain them in substantially proper position for transfer to the shuttle. The bobbin seats preferably are inclined to the radii of the hopper so that when a bobbin reaches transferring position, the positioning faces of its butt are slightly inclined to the vertical and any rotative movement of the bobbin caused by engagement with a guide in the shuttle will tend to position the bobbin in the shuttle Jaws.

The guiding means for retaining the rotative position of the bobbin unchanged as it is being transferred from the hopper to the shuttle comprises a conveyer or chute 23 having walls 24 adapted to form continuations of the walls of the bobbin seat which is in transferring position.

The conveyer has an extension 25 which is slidably mounted upon the extension 6 of the bracket stand and is held down upon said extension by a plate 26 which may be secured to the bracket, stand by the same rivets or bolts 27 which secure the abutment 7 thereto. The end of the conveyer extension 25 is flanged upwardly to form a seat for a helical spring 2 8 which rests its oppo site end against a post 29 secured to or formed integral with the hopper stand bracket 6. It will be noted that the hopper construction and hopper bracket construction illustrated herein are substantially the same as those illustrated in my prior Patent No. 1,185,094 and that the only modification of the patented structure which is necessary to permit the embodiment of the improve ment herein is to cut away the portion of the lateral extension of the hopper stand bracket from the points a to 7) preferably leaving a supporting ledge c therebetween' for the extension 25 of the conveyer.

In the operation of the device the actuation of the transfer arm forces the bobbin from the hopper into the inclined guideway of the conveyer or chute 23. The force of the transfer arm first causes a rotation of the hopper as the bobbin is maintained against the abutment 7 by the bobbin support 9. As the bobbin passes from the hopper into the conveyer the latter is moved rearwardly against the action of the spring 28. This movement of the conveyer is in consonance with the movement of the lay as it approaches transferring position so that the action of the reciprocating conveyer has the double function of maintaining the bobbin against rotative movement during transfer and also of providing a longer period in which the conveyer and shuttle are in registry or communication. This insures the proper positioning of the slabbed positioning faces of the bobbin butts between the guiding means on the shuttle jaws.

It is to be understood that various modifications of construction may be made within the scope of the invention defined by the following claims and also that while the guiding means interposed between the hopper and shuttle have been described with particular reference to the use'of bobbins having feeling slots in the barrels thereof it is adapted to be used with bobbins of the usual type for the purpose of more effectively insuring transfer.

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

1. A filling replenishing loom comprising a hopper adapted to contain a plurality of filling carriers, a transferrer and means to actuate the same to thrust a filling carrier into the shuttle, a slidably mounted conveyer intermediate of said hopper and shuttle provided with guiding instrumentalities adapted to engage and position the filling carrier being transferred and so disposed as to cause said conveyer to be moved rearwardly into registry with the shuttle by the movement of the filling carrier under the influence of the thrust of the transferrer.

2. A filling replenishing loom comprising a rotatable hopper having a peripheral series of filling carrier seats inclined to the radii of the hopper, a transferrer and means for actuating the same to thrust a filling carrier into the shuttle and a slidably mounted conveyer intermediate of the hopper and shuttle having guiding instrumentalities adapted to receive a positioned filling carrier from the hopper and to maintain the filling carrier in the same rotative position during transfer, said conveyer being movable into registry with the shuttle by the movement of the filling carrier under the influence of the thrust of the transferrer.
