FILLING-POSITIONING DEVICE FOR LOOMS.

Specification of Letters Patent.

Patented Dec. 29, 1914:.

Application filed December 22, 1913. Serial No. 808,113.

To all whom it may concern Be it known that I, FRANK D. HERRING, a citizen of the United States, residing at Lindale, county of Floyd, State of Georgia, have invented an Improvement in Filling- Positioning Devices for Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

It is common in automatic filling replenishing looms to provide means for parting or severing the filling close to the filling carrier containing the filling supply to be abandoned at the time a change of filling carriers is effected. Such filling parting means are frequently attached to and moved with the shuttle feeler which prevents filling transfer taking place when a shuttle has been improperly boxed at the transfer end of the loom. Such filling parting means and such specific filling parting means carried by the shuttle feeler are disclosed in the patent to Draper No. 683,423, granted September 24, 1901, in connection with the well known Northrop type of automatic filling replenishing loom. It sometimes happens that the filling trailing behind the fillingcarrier from its position at the transfer end of the loom does not get into the path or field of operation of the thread parting means, and hence is not severed. This may be due to the shuttle rebounding slightly or sufiiciently to lower the run of filling onto or adjacent to the bottom of the raceway or to other causes. When the failure to part the filling takes place an undue strain is placed upon the pick last beaten in, causing liability to injury to the cloth, and the broken filling end left after transfer takes place will not be cut by the usual temple thread cutter at the selvage, but will be liable to snap back or be worked into the shed and woven in, causing an imperfection.

It is the object of the present invention to provide a means for positively insuring the position of the filling to be parted in the field of operation of the parting means, and to insure the actuation of the filling positioning means upon the call for filling replenishment.

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

The drawings represent so much of the mechanism of an automatic weft replenishing loom of the Northrop type as is necessary to a disclosure of the present invention, together with the parts forming the preferred form of this invention applied thereto.

In the drawings: Figure 1 is a top plan view, broken out at each side and centrally, of a sufiicient portion of an automatic filling replenishing loom with the preferred embodiment of this invention applied thereto; Fig. 2 is a front elevation of a portion of the lay showing the parts directly concerned with the positioning of the filling; Fig. 3 is a view in transverse cross-section taken on the line cc-m Fig. 1.

The general construction and operation of the automatic filling replenishing loom herein illustrated with the exception of the parts required to embody the present invention is familiar and is disclosed in a number of patents, such as that to C. H. Draper No. 683,423 above referred to, or that to Rhoades No. 1,020,622 granted March 19, 1912.

The lay 1 having the shuttle boxes 2 at the feeling end, and 3 at the transfer end, the hopper or feeder 4 containing a supply of full filling carriers such as the bobbins 5, the breast beam 6, weft fork 7, the filling feeler 8, the transferrer arm 9, and the connections by which upon the indication of a predetermined degree of exhaustion of the running filling by the feeler 8 the transferrer arm 9 is operated to transfer the filling as by forcing a fresh bobbin from the hopper into the shuttle therebeneath and ejecting the spent bobbin, are all familiar and need no detailed description. It will be remembered, however, that upon the call for filling replenishment as by the indication of a predetermined degree of exhaustion in the running filling by the feeler 8 a controller rock shaft 10 is rocked to effect the operation and positioning of the parts necessary to secure the transfer, and in the preferred form of the invention herein illustrated this controlling rock shaft is made use of, preferably through an arm already connected thereto, for the support and operation of the actuating elements in the filling positioning means.

The loom is shown as provided with a suitable filling parting means and the ordinary thread, parting means carried by the ordinary shuttle feeler, such as shown in the. patents previously referred to is illustrated. The shuttle feeler shown at 11 comprises a swinging arm pivoted on the loom frame at 12, and adapted to swing into position so that as the lay beats up it will feel for the boxed shuttle immediately in the, rear of its proper position so that if the shuttle is improperly boxed the shuttle feeler will strike the shuttle and through the usual connections prevent transfer taking place. The shuttle feeler is moved into operative position by the usual slotted arm 13 engaging the lug 14: connected with the dog 15 which dog is thrown into the path of the hunter 1.6

on the lay upon the call for filling replenishment. The thread parting means may also be of any suitable construction and operation, and is herein illustrated as of usual form and is herein illustrated at 17 carried and supported by the shuttle feeler 11. It is shown as the same construction as illustrated in the patents above referred to, and comprises not only a filling parter but a filling clamp to seize and hold the end of the filling and carry it back into the path of the. usual temple thread cutter, not herein shown. In this type. of mechanism the controller rock shaft 10 is; usually provided with and fast upon it an arm 18 connected to one end of a strong spring 19 which at its lower end is secured to the loom frame, said spring holding the arm in the position shown in Fig. 4 upon a pin 20 on the shuttle feeler support 11 and eccentric to the fulcrum or pivot 12 thereon, thus maintaining the shuttle feeler and thread parting means carried thereby in the normal orinoperative position, shown in Fig. 4. In addition, to these familiar features of construction the form of the invention herein illustrated in connection with this form of 100m provides a vieldingly depressed lifter device mounted on the lay adjacent the shuttle-box in Whi ch transfer takes place and normally flush with or below the bottom of the raceway and a striker carried by the breast beam normally out of the path of this lifter device, but moved upon the call for filling replenishment into the path thereof, so that when the lay heats up the lifter device will be elevated to a position to hold the filling accurately in the path of the filling parting means.

A bracket 21 is fastened to the face of the lay and is provided with a vertical bearing 22 and a depending guide 23. The lifter device comprises a vertically movable standard 24 mounted to slide in the bearing 22 and provided at its lower end with an arm 25 guided in a slot in the guide 23. spring 26 between the arm 25 and the lay serves to maintain the standard in lowermost position. At its upper end the stand and is formed into orhas-eonneoted there-.

With an arm 27 projecting across the raceway immediately behind the position which the shuttle occupies when boxed. In the construction shown the standard 24 is bent to run parallel at 28 with the lay and then bent rearwardly to cross the raceway. The portion 28 is in two parts hinged or pivoted together and provided with a light spring 29 holding the parts in normal position, but

enabling the arm 27 to be swung downwardly by a slight pressure. The raceway is cut away beneath the arm 27 so that the arm lies flush with or below the level of the raceway so as not to interfere with the movement of the shuttle back and forth on the raceway. These parts occupy normally the position shown in Fig. 2 being entirely inactive and in no way interfering with the usual operation of the loom parts.

A striker is carried by the breast beam opposite the arm 25 and brought into the path thereof when it is desired to effect the operation of the positioning means. This haustion of the filling has been indicated by the feeler 8 and the controller rock shaft 10 has been revolved to elevate the arm 18, the striker30 will be carried therewith into a position so that when the laybeats up the arm 25 will ride up the cam surface 32 el'evating the arm 27 and carrying with it the filling, thus positioning and holding the filling accurately in the path of the parting means. The arm 27 is vertically adjustable as by means of the set screw 33 so that the position of the filling may be regulated in accordance with the path or field of operation of the thread parting means. Since the arm 27 is not elevated until the lay beats up into. the path of the striker 30 the shuttle has already passed over the arm 27 in its de-. pressed position and enters the box at the, transfer end. If the shuttle should slightly rebound or in any way be thrown back after passing over the arm 27 provision is madev for preventing injury to the parts by the.

spring connection of the portion 28 of the-- tion lying beneath the plane of the raceway, and when the standard is in its operative position acting to position and holdthe filling in the path of the parting means, but yielding if struck by the shuttle, and means carried by the lay for moving said standard into operative position upon the call for filling replenishment.

2. In an automatic weft replenishing loom a shuttle feeler movably mounted on the loom frame and when moved into operative position acting to feel for and detect, when the lay beats up, an improperly boxed shuttle at the transfer end of the loom, thread parting means carried by said shuttle feeler topart the filling in the rear of the shuttle when the lay heats up, filling positioning means mounted on the lay and normally below the raceway and movable upon the call for filling replenishment to raise and: position the filling in the path of said parting means.

3. In an automatic weft replenishing loom a shuttle feeler movably mounted on the Copies of this patent may be obtained for loom frame and when moved into operative position acting to feel for and detect when the lay beats up an improperly boxed shuttle at the transfer end of the loom, thread parting means carried by said shuttle feeler to part the filling in the rear of the shuttle when the lay beats up, a yieldingly depressed lifter device mounted on the lay and normally flush with or below the bottom of the raceway, a striker normally out of the path of said lifter device, and means actuated upon the call for filling replenishment to move the striker into the path of the lifter device as the lay beats up, thus to raise the lifter device to position and hold the filling in the path of the parting means.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

Rom. MCOALLEY, \VM. WALTER.
