21 Claims.

This invention pertains to automatic filling replenishing looms and more particularly relates to methods of and gauges for adjusting the shuttle feeler and picker stick thereof.

As generally constructed automatic filling replenishing looms includ a reciprocating lay carrying at each end thereof, at least one shuttle box, and replenishing mechanism including a magazine at one end of the breast beam carrying a number of reserve filling carriers, and suitable actuating mechanism provided to automatically eject a filling carrier from the shuttle and to insert a fresh carrier therein upon the detection of filling absence by the filling detecting device. In looms of this type it is essential that the shuttle be properly positioned in the shuttle box relative to the magazine so that a transfer can be made. The position of the shuttle in the shuttle box is determined by the shuttle feeler and the picker. Accordingly it is essential that the shuttl feeler and picker be adjusted so that when the shuttle comes to rest in the shuttle box it will be in proper position, relative to the magazine, for transfer.

Accordingly it is a principal object of this invention to provide in an automatic filling replenishing loom including a magazine, a lay having a shuttle box thereon, a shuttle feeler, a shuttle and a picker stick, a shuttle position gauge comprising indicating means carried by the magazine and indicating means in the shuttle whereby upon alignment of the indicating means said shuttle will be properly positioned in the shuttle box, relative to the magazine for transfer.

A further object of this invention is the provision of a new and improved method of adjusting the shuttle feeler and picker stick to position the shuttle in the shuttle box in operative relation to the magazine, for transfer.

These and other objects of the invention are accomplished in the construction illustrated on the accompanying drawings, wherein;

Fig. l is a plan View of the right hand end of the lay and shuttle box showing parts thereof broken away;

2 is a rear view partly in section and with parts thereof broken away of the right hand end of the lay, shuttle box and magazine showing one modification of the gauges of this invention mounted in position for use;

Fig. 3 is a view in perspective of one modification of the shuttle positioning gauge;

Fig. i is a View similar to that of Fig. 2 but showin a second modification of the shuttle position gauge;

Fig. 5 is a view similar to that of Fig. 2 but showing a third modification of the shuttle position gauge;

Fig. 6 is a view in perspective of th gauge shown in Fig. 4; and,

. in the shuttle box.

Fig. '7 is a view in perspective of the shuttle position gauge shown in Fig. 5.

The drawings show a portion of the right hand end of the lay with the right hand shuttle box and portion of the replenishing mechanism. The

other parts and mechanisms of the loom, not

shown, may be of any suitable usual construction and form no part of the present invention.

The drawings show part of the right hand end of the lay, including a lay beam l, picker stick 2, carrying a picker 3, a shuttle feeler indicated generally at 4 and parts of the right hand shuttle box including th front box plate 5, back box plate 6 and floor plate l'. A shuttle 8 is shown The shuttle has a spur 9 on one end and a spur ill on the other end and is provided with a bobbin engaging spring I I.

It is essential to the proper operation of the filling replenishing mechanism that upon transfer the shuttle be in proper position with respect to the magazine. As the position of the shuttle in the shuttle box depends upon the position of the picker stick, the position of the picker stick must be adjusted so that each time the shuttle comes to rest with the spur of the shuttle firmly pressed against the picker, the shuttle will be properly positioned for transfer.

The picker stick 2 oscillates in a slot in the bottom of the shuttle box as the shuttl is picked into and out of the box. When the shuttle is at rest in the shuttle box as shown on Fig. 2, the picker stick is at the outer end of the slot and rests against a buiier pad in the outer end of the slot. The pad may comprise a lay end strap I2 made of leather or other suitable material. A padding l3 made of leather or other suitable material is placed beneath the strap 42. The position of the picker stick and thereby of the picker is adjusted by increasing or decreasing the thickness of the padding.

When a call for replenishment of filling has been made by the filling feeler mechanism, not shown, the shuttle feeler 4 is raised to feeling position to feel the shuttle as the lay moves forwardly to see if it is properly boxed. If the shuttle is not properly boxed, that is if th feeler contacts the shuttle and cannot push it into proper position in the box, the feeler revokes the call for transfer and no transfer takes place. When the shuttle is properly boxed the spur of the shuttle should move past the shuttle feeler with a slight clearance therebetween.

In the proper operation of the loom the shuttle feeler should clear the spur of the shuttle when.

the shuttle is properly boxed for transfer and means are provided for adjusting the position of the shuttle feeler to give this clearance.

The means for adjusting the shuttle feeler may comprise a pair of spaced fitting strips M|5 on the shuttle feeler tip H5 at the junction of the tip with the shuttle feeler arm ll.

The clearance between the shuttle feeler and the spur of the shuttle may be adjusted by filing either strip M or [5. In addition to this means of adjustment, the bracket (not shown) by which the shuttle feeler is mounted on the loom frame may be provided with fitting strips.

From the foregoing it is seen that for proper adjustment of the picker stick and shuttle feeler the shuttle must first be properly positioned in the shuttle box in relation to the magazine.

To properly position th shuttle relative to the magazine for transfer gauge means are provided. Suchgauge means may comprise a male and a female gauge member.

The male gauge member may comprise a spindie It! of the same fength as that of the filling.

thereon. The rings '20 may be metallic rings mounted on the head or projecting ribs formed,

a The spindle is is provided with indicating means located at a predetermined distance. from the head It. The indicating means may comprise a laterally extending projection or abutment 2|. The projection 2| may be formed integral with the spindle IE or as a separate member fixedly attached thereto. The projection 2! has a rounded free end 22 provided with flat parallel machined sides for a purpose later to be described.

The female gauge member may comprise a spindle 23 made of wood or metal or any other suitable material. The spindle 23 has at one end an enlarged cylindrical head or butt '24. The head 24 is of the same size as the head of the filling carriers used in the loom and is provided with a plurality of raised spaced ribs or rings 25. The head 24 maybe formed integral with the spindle 23 or may be a separate member fixedly mountedthereon. The rings 25 may be metallicrings mounted on the head or projecting ribs formed integral therewith. The spindle 23 is providedwith indicating means located at a predetermined distance from the head 24. The indicating means may comprise a laterally ex tending projection 'or abutment 26. The projection 26 maybe formed integral with the spindle 23' or as a separate member fixedly attached thereto. 'The' outer end o'f the projection 25 is integral therewith.

provided with a recess 21, having parallel machined side walls, for the reception of the free end'2; of projection 2|.

The shuttle position gauge of my invention is adapted to be used with any type of magazine in'which a reserve supply of filling carriers are maintained and'in which each carrier is successively brought into a position over' the shuttle for transfer by a transferrer. The particular magazine shown on the drawing is of the rotary battery type and includes a transferrer 28, a disc 29 provided with spaced circumferential pockets tllfor reception ofthe bobbin butts, and a disc 3! provided with spaced circumferential pockets 32 for the reception of the bobbin tips. The pockets 3?. may be mounted on disc 3i and spring I 33 may be employed to permit resilient movement between the disc, and the pockets.

As shown on Fig. 2 the male member is placed in the battery in the position ordinarily occupied by a bobbin when in transfer position. The female member is placed in the shuttle in the position ordinarily occupied by the bobbin with the head engaged by the bobbin gripping spring, then by moving the shuttle in the shuttle boX until the male projection 22 fits into the recess 21. of the female projection 26 the shuttle is brought into proper position relative to the battery and transferrer for transfer.

A new and successful method of adjusting the position of the picker stick and the shuttle feeler may be followed by using the shuttle positioning gauges of this invention.

Such method may comprise the steps of first positioning the shuttle in proper operative relation to the magazine by moving the lay to the front center, then mounting the male gauge in the magazine and the female gauge in the shuttle and then aligning the projections of the two between the shuttle spur and shuttle feeler and when the shuttle is stopped for transfer it will be properly positioned relative to the magazine for transfer.

Another modification of the gauge member is shown in Figs. 4 and 6. The gauge as shown in this modification may comprise a spindle 34 made of wood or metal or any other suitable material. The spindle 35 has at one end an enlarged cylindrical head or butt 35. The head 35 is of the same size as the heads of the filling carriers used in the loom and is provided with a plurality of raised spaced ribs or rings 36. The head 35 may be formed integral with the spindle 34 or may be a separate member fixedly mounted thereon. The rings 36 may be metallic rings mounted on the head or projecting ribs formed integral therewith. The other end of spindle 34 extends upwardly and forwardly over the head 35 as seen on Fig. 6. The extreme end 31 being in substantially the same vertical plane as the head 35.

As shown on Fig. 4 the gauge is placed in the shuttle with the head 35 engaged by the bobbin engaging spring ll. Then the shuttle is moved in the shuttle box until the end 31 abuts the rear wall of the pocket 38. When in this position the shuttle is properly positioned relative to the magazine for transfer and is locked against longitudinal motion inwardly of the lay.

The modification of the gauge as shown on Figs. 5 and '7 may comprise a spindle 38 made of wood or metal or any other suitable material. The spindle 38 has at one end an enlarged cylindrical head or butt 39. The head 39 is of the same size as the head of the filling carriers used in the loom. The head 39 may be formed integral with the spindle 38 or may be a separate laterally extending projection 40. The projection 40 may be formed integral with the spindle 38 or as a separate member fixedly mounted thereon. Projection 40 extends laterally from spindle 38 then extends substantially parallel therewith in a direction towards the head 39. The free end of the projection 40 forms an abutment 4| lying in substantially the same vertical plane as the head 39.

As shown on Fig. 5 spindle 38 is mounted in the battery in the position ordinarily occupied by a bobbin when in transfer position. When in this position the projection 40 will extend into the shuttle in the opening therein ordinarily occupied by a bobbin. By moving the shuttle in the shuttle box until the free end or abutment iii of the projection 40 engages the cover 22 of the spring II in the shuttle, the shuttle is brought into proper operative position relative to the magazine for transfer. With the shuttle properly positioned relative to the magazine, the picker stick and shuttle feeler may be adjusted in the manner previously described.

When using the modifications shown in Figs. 6 and 7 the method of adjusting the picker stick and shuttle feeler as set forth above may be followed. However the gauges shown in Figs. 6 and 7 provide for locking the shuttle against longitudinal movement in one direction only. In the modification shown in Fig. 7, however, the projection 40 may be provided with a head adapted to engage the bobbin engaging spring in the shuttle and thereby positively lock the shuttle.
