FILLING, CLAMPING, AND PARTING MEANS FOR LOOMS.

Application filed August 23, 1921. Serial No. 494,527.

To all whom it may concern:.

Be it known that I, ALoNzo E. RHoADEs, a citizen of the United States, resident of Hopedale, county of Worcester, Stateof Massachusetts, have invented an Improvement in Filling, Clamping, and Parting Means for Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to the means for actuating the filling clamping and parting means of an automatic filling replenishing loom.

The object of the invention is to provide an adjustable bunter on the lay for actuating the filling clamping and parting means.

The object of the invention is further to provide a hunter of this type which may be accurately adjusted and securely locked in adjusted position so as not to be disturbed from its adjusted position notwithstanding the heavy shocks and jars to which it is subjected in the operation of the loom.

The nature and object of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

In the drawings:

Fig. l is a View in vertical cross section looking toward the inside of the transfer end of the loom.

Fig. 2 is a detail in plan and partially in horizontal cross section of that portion of the lay in which the hunter is mounted.

Fig. 3 is a front elevation of the construction shown in Fig. 2.

The invention in its preferred form. is shown in connection with an automatic filling replenishing loom of the well known Northrop type and as that type of loom is well known and familiar to those skilled in the art, no detailed illustration or description, except of those parts immediately concerned with the present invention, is necessary.

In this type of loom the frame, one side of which is shown at 1, supports the breast beam 2 upon which is mounted at the transfer end or side of the loom the stand 3 of the magazine 4 carrying the supply of fresh filling carriers, one of which, in this case a bobbin, 5 is indicated in position ready for transfer.

The lay, which in the operation of the loom is swung toward and from the breast beam, comprises the vertically arranged swords, one of which is shown at 6, and the cross bar or lay proper 7. The shuttle 8 is picked back and forth on the top surface of the lay and at the end portions of the lay rides on a race plate or extension 9 of the shuttle box.

In this type of loom when the filling in the running shuttle is substantially exhausted, that fact is indicated by mechanism of a suitable and familiar type which thereupon acts to initiate the filling replenishment or the transfer of a fresh filling carrier from the magazine to the lay and the discharge of the substantially exhausted filling carrier from the lay. When such transfer takes place, it is necessary to sever the filling extending from the selvage to the filling carrier to be abandoned. Such severance is commonly effected in two places, first, adjacent the end of the shuttle at the transfer end of the loom and second, adjacent the selvage of the cloth. For the former purpose is provided a mechanism known as the filling clamping and parting mechanism, because it both clamps the filling and parts it close to the shuttle and then carries it forward so as to bring it into the field of action of the usual temple thread cutter which is the mechanism provided for the second purpose.

This filling clamping and parting mechanism is illustrated as of a familiar form and comprises relatively fixed blades 10 and an intermediate relatively movable or pivoted blade 11. These blades are mounted on a suitable support movable toward and from the lay and here, as is usual, the shuttle feeler 12 pivotally mounted on the frame at 13 is utilized for that purpose. The. movable blade 11 is provided with a laterally extending pin 14 and a forwardly depending tail 15. It is also limited in its closing movement by a pin 16 mounted in the support or shuttle feeler co-operating with an aperture 17 in the blade. In normal position the parts stand as illustrated in Fig. 1 with the blades of the filling clamping and parting mechanism closed.

\Vhen in the course of the operation of the loom the running filling has become substantially exhausted and the mechanism for initiating the filling replenishment has been set into operation, the shaft 18 extending across the front of the loom is rocked to raise the rearwardly projecting arm 19; This arm, being connected to the shuttle feeler 12, swings the shuttle feeler rearwardly carrying with it the filling clamping and parting means. As the shuttle feeler swings rearwardly, the pin 14 extend ing from the movable blade 11 rides against the lower cam face of the switch cam 20 pivoted at 21 on the bracket 22 and thus moves the movable blade to open position.

If now the shuttle is properly boxed at the transfer end of the loom, the nose of the shuttle feeler passes in front of the shuttle and the dog 23 which is pivoted to the downwardly projecting arm 24 of the transferrcr 25 pivoted in the magazine at 26 is swung up so as to stand in the path of the transferrer hunter 2? on the lay. As the lay heats up this transferrer bunter 27 striking the dog 23 causes the transferrer 25 to swing downwardly and drive the fresh filling carrier 5 in position for transfer into the shuttle 8 on the lay therebeneath and discharge from the shuttle the substantially exhausted filling carrier. At the same time a hunter 28 on the lay engages the depend ing tail 15 of the movable blade 11 and swings it into closing position, thus clamping and parting the filling end close to the nose of the shuttle. At the conclusion of the transferring operation the shuttle feeler swings forwardly and the pin 14 swings the switch cam 20 forwardly and passes beneath it. The filling end is therefore carried forwardly and thus the filling is brought into the path of the usual temple thread cutter atthe selvage where it is again severed.

The parts thus described, that is, the shuttle feeler, the transferrer, the filling clamping and parting means, the switch cam, etc., all have to be assembled and adjusted into proper relation with each other and into position so that they will all operate and function to secure the results stated. This assembling and adjustment is not an easy matter to secure,but by the provision of the adjustable bunter involved in this invention these desired results are readily secured, because after the parts are assembled and adjusted the final adjustment may readily be made by means of the hunter and if. for any reason. readjustment of the parts becomes necessary the hunter may be readily readjusted to secure the proper cooperative relation of all the parts. The hunter. however, must be capable of functioning in its adjusted position and without danger of being disturbed therefrom notwithstanding the heav shocks and jars to which it is subjected uring the beat-up and in the operatlon of the loom.

This bunter 28 in the preferred form is constituted as a metal plate mounted to slide in and transversely of the lay and to project forwardly from the lay in the path of the tail 15. It is preferably of substantial width and, if necessary, may be recessed at 29 so as to fit under the transverse groove 30, usually found in the race plate 9, to provide for the shuttle-feeler. In the preferred form illustrated this bunter is mounted in the lay beneath but in upper contact with the metal race plate 9. A set screw 31 is mounted in the lay, as in the flanged portion of the lay sword 6, and is adjustable therein transversely of the lay and abuts the rear end of the bunter 28. This set screw 31 is threaded into the lay sword and is provided with a suitable lock nut 32. Near its front end the hunter 28 is slotted transversely of the lay at 33. A set screw 34 is countersunk in the race plate 9 and projects therefrom and through the slot 33 in the bunter and is threaded into a nut 35 seated in the body of the lay.

It will thus be seen that by loosening up the screw 34 and the lock nut 32 and by turning the set screw 31 a very accurate adjustment of the hunter 28 transversely of the lay, so as to vary the extent of projection of its forward end, may be secured. Then upon tightening up the lock nut 32 and setting up the screw 34 the hunter will be firmly locked to the lay. In this case when the set screw 34 is set up the hunter is firmly clamped between the race plate 9 and the nut 35 and thus firmly locked to the metal race plate. Not only, therefore, is accuracy of adjustment secured but the hunter, being abutted by the set screw 31 and locked by the screw 34, is prevented from moving out of its adjusted position or being disturbed therefrom notwithstanding the shocks and jars to which it is subjected.

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