Application filed May 18, 1925. SerialNo. 31,000.

To all whom it may concern:

Be it known that 1, JOHN C. Bnoons, a citizen ofthe United States, residing in Paterson, in the county of Passaicand State of New Jersey, have invented an Improvement in Feeler Mechanisms for Looms, of which the following description, in connection with the accompanying drawings, isa specification, like characters on the drawings repre senting like parts.

This invention relates to feeler mechanisms for looms whereby the operative condition of the loom is changed from time to time, and more particularly to feeler mechanisms of the magnetic type.

Heretofore, magnetic feeler mechanisms have been devised, but their operation in practice has not been satisfactory owing to conditions attending their operation, and one of the purposes of the present invention is to provide a feelermechanism of the magnetic type which shall be simple in construction and effective and satisfactory in operation.

In accordance with the present invention, the feeler itself is mounted to be drawn rearwardly upon detection of substantial exhaustion of the filling, to thereby position parts relative to each other for effecting a change in the loom operation,- such as replenishment of filling, on the following detecting beat of the lay. In carrying this feature of the invention into effect, the feeler itself is mounted for movement towards and from the front of the loom in bearings which permit the feeler a bodily movement transversely to its rearward movement when it is drawn rearwardly on detection of substantial exhaustion of filling, to thereby relatively position the feeler and ashouldered member for effecting replenishment of filling when the feeler is again moved frontwardly on the next detecting beat of the lay.

The feeler mechanism of the present invention is applicable to either the'replenishing or opposite side of the lay, and the parts are so arranged that on the frontward movement of the feeler when engaged with the shouldered member, it will itself be withdrawn frontwaidly out of the shuttle box, to thereby permit a change of filling carriers in the shuttle should the feeler be employed at the replenishing side of the loom.

parts of a loom at the shipper side, containing the present invention, the parts being shown in their normal position;

Fig. 2 is an enlarged sectional side elevation of the feeler mechanism of the-present invention, showing the feeler as having been drawn rearwardly on detection of substantial exhaustion offilling; v

Fig. 3 is a similar sectional side elevation showing the relation of parts initially positioned for effecting replenishment of filling; and

Fig. 4 is an enlarged detail showing a filling carrier or bobbin which may be advantageously employed in connection with the feeler mechanism of the present invention.

The feeler mechanism is shown associated with loom replenishing devices, but thelatter are not illustrated because the details thereof form no part of the present invention and are now well understood in the art.

The loom frame 1 has mounted on the breast beam 2 thereof the bearings 3, one at each side of the loom, in which is supported the transverse or rock shaft 4 from which rises the arm 5 connected at 6-to a rearward- 1y extending arm or actuator 7. The rear portion of the actuator 7 is provided with'a finger 8 adapted to be engaged at times by an operating member 9 which may be the cam follower or a part associated therewith.

Underlying the actuator 7 is the arm 10 pivotally mounted on the loom frame at 11' and having the usual cam portion 12 above which extends an arm 13 pivotally supported at 14 and normally pressed rearward by a spring 15. This train of devices between the feeler mechanism andthe transverse or rock shaft 4 is, or may be, of usual type, or be varied, if desired, the essential being that on detection of substantial exhaustion of filling and call for replenishment, the actuator shall be placed inoperative relation with the operating member 9. p

The lay 16 may be of usual construction and has the shuttle box 17, the front wall of which has an opening 18 which registers with a similar opening 19 in the front wall of the shuttle 20 when the latter is in the shuttle box. These parts may be of usual construction.

Adjustably mounted on the shipper stand 21 is the feeler support or stand which, as shown, comprises a base 22, Fig. 2, having slots through which pass the bolts 23 for securing the shipper stand in place.

The feeler stand has a front and a rear bearing for the feeler, and as shown the front bearing comprises an opening 24 in the upwardly extending member 25 of the feeler stand, the lower wall of the bearing 24 being chamfered or cut away from its center towards its edge portions, as indicated at 26. The rear bearing for the feeler is formed in the upstanding member 27 and is also chamfered on its lower wall by a downward inclination thereof, as indicated at 28, the construction being such that the feeler 29 may not only have a movement towards and from the front of the loom in such bearings, but also a movement transversely to its frontward and rearward movement, or, as in the present instance, in a downward direction, as will presently apear.

The feeler 29 at its front portion adjacent the front bearing is cut away or recessed at 30, and through a slot or opening 31 therein extends the arm of a lever pivoted at 33 and having the frontwardly extending flat portion 3%, on the top of which is adapted to bear the spring which, in the present instance, is shown as a leaf spring, having its front end portion 36 upturned, the construction being such that the spring acts through the pivoted lever to normally hold the feeler in its position of detection of filling, but with permissive movement both rearwardly and front-wardly, as will further appear.

The tip end portion 37 of the feeler may be formed either as a permanent magnet or it may be an electric magnet by the use of the electric wires 38, but the details of such magnet or electric magnet may be varied widely within the true scope of the invention, the essential being in this respect that the tip portion of the feeler will be magnetized to cooperate with a metal band 39, which may be secured to the filling carrier or bobbin 40, otherwise of usual type, as indicated in Fig. -l, the construction being such that when the feeler detects substan tial exhaustion of filling in the shuttle on a detecting beat, it will be drawn rearwardly, and to limit such rearward movement, a stop 41 is adjustably secured to the feeler frontward of the rear bearing 27.

\Vhen the feeler is drawn rearwardly as the lay goes back on a detecting beat and upon substantial exhaustion of filling, which uncovers the band 39, it will drop in the chamfered bearings 26, 28, as indicated in Fig. 2, and advantage is taken of this drop ping or transverse movement of the feeler on its rearward drawing movement to operatively position the parts for effecting replenishment of filling on the following detecting beat.

The feeler 29 has adjustably secured thereto a projection or tooth 42 which may be clamped in adjusting position by a bolt 43, and below the feeler is mounted a shouldered member or slide l l having a shoulder l5 adapted to be engaged by the projection 42 when, as the feeler is drawn rearwardly, it is lowered or moved transversely in its chamfered bearings.

The shouldered member or slide 14 is mounted in the front and rear upstanding members 25 and 27 and has a collar 46 wnich may appropriately limit its rearward movement.

Pivot-ally mounted in the feeler stand at 4-7 is the dog positioner, shown formed as a lever, one arm 48 of which normally rests against the front end portion 49 of the shouldered member or slide 44, and the other arm 50 of which is connected at 51 to a link 52, the lower end portion of which has a slot 53 which engages a pin M on a dog which is itself connected at 56 to the downwardly extending arm 57 of the transmitter 13, the construction being such that should the dog be moved frontwardly it will act through the transmitter to operatively relate the parts for effecting replenishment of filling.

in accordance with the present invention, the lay 16 has mounted thereon a bunter which is adapted to engage the dog when the latter is operatively positioned by the dog positioner. Adjacent the bunter 58 is a lug 59 which, when the dog positioner has been initially moved by the shouldered member or slide ia, engages the inclined end portion 60 of the dog positioner which has been initially raised, as indicated in Fi 3, and thus insures that the dog itself shall be moved to operative position with relation to the bunter 58. By this construction of the lug 59 and inclined end 60 of the dog positioner, the stress of moving the dog 'nto the path of the bunter is removed from the shouldered member or slide after the initial positioning of the parts.

The front end portion of the feeler is provided with a downturned too or foot 61, and between it and the shoulderd member or slide 44 extends the enlarged end portion of the arm 48 of the dog positioner, with the result that when the dog positioner assumes its full transferring position, the feeler itsself will be moved frontwardly or withdrawn from the shuttle box.

From the construction hereinbefore described as one good practical form of the present invention, it will appear that during normal weaving operations with a workin supply of filling in the shuttle, the fteeler will be given a frontward movement on its detecting beat and thereby swing the lever 32 frontwardly, and as the lay goes back the spring 35 acting upon the fiat portion 34: of the lever 32 will return the feeler to its initial position. When, however, the filling had become substantially exhausted and the metal band 39 on the filling carrier or bobbin is exposed, the magnet or magnetic tip 37 of the feeler will cause the ieeler to be withdrawn rearwardly as the lay goes back, thereby bringing the recessed portion 30 of the feeler rearward to permit a drop of the feeler and cause the projection 42 to engage rearward of the shoulder 45 extending from the slide 44. On the next detecting beat, the feeler will again engage the filling carrier or bobbin in the shuttle and be moved frontwardly thereby. Such trontward movement of the feeler on the second detecting beat effects frontward movement of the shouldered member or slide 14;, thereby actuating the dog positioner and operatively relating the parts to effect replenishment of filling.
