LATHAM, OF 'W'ORCESTER, MASSACHUSETTS, ASSIGNOR TO CROMPTON 8c KNOWLES LOOM WORKS, OF WORCESTER, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS CLOTH-ROLL MOUNTING Application filed ctober 25, 1928. Serial No. 315,065.

This invention relates to improvements in cloth roll mountings for looms and it is the general object of the invention to provide for locking the mounting positively when the roll is in normal or clothwinding position in such a way that the cloth roll may be read ily disconnected from its mounting to permit removal of the cloth.

As the cloth is woven in a loom-it moves forwardly to a cloth roll which is driven by constantly moving means to wind up the cloth. From time to time it becomes necessary to remove cloth from the loom and to permit this operation it iscustomary to provide quickly removable mountlngs for the cloth rolls. The rolls are provided with square openings into which may be fitted the squared end of a supporting stud. It 1s an important object of my present 1nvent1on to provide a stud which is free to rotate with the cloth roll and having in saidstud an annular groove to receive a lock which may be removed from the groove to permit endwise movement of the stud in a direction parallel to the cloth roll. 7

In certain devices heretofore used to mount the cloth rolls the lock hasbeen so formed as to be concentric with the roll and when the latter rotates there is a tendency to lift the lock out of locking position unless the lock is properly lubricated. When the lock becomes disengaged the cloth roll is likely to fall on the floor and soil the cloth. It is a further object of my PIGSGllb'lIlVEIlflOIl to provide a lock which moves about a center eccentric with respect to the axis of the cloth may be given a plurality of longitudinal positionsto compensate for varying lengths the cloth roll.

With these and other objects in view which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth in the claims.

In the accompanying drawings wherein one form of my invention is shown,

Fig. 1 is a front elevation of the lower portion of a loom having my invention applied thereto certain parts being shown in section and other parts being removed for the sake of clearness,

Fig. 2 is a vertical section on line 22 of Fig. 1,

Fig. 3 is atop plan view taken in the directlon of arrow 3, Fig. 2,

Fig. 4 is a Vertical section on line 4-4 of Fig. 2, and

Fig. 5 is an end view looking in the direction ofarrow 5,Fig. 4.

Referring to Fig. 1, the loom frame may be provided with a lower girt 11 which sup ports a pair of vertical stands 12 and 13 located respectively at the right and left hand sides of the loom. Driving gearing indicated generally at 14 is provided for rotating part of the loom. The right hand end of the cloth roll may be supported on a head 15 non-circular 1n cross section, being suggested herein as square, said head being associated with a handle wheel 16 by which the clot-h roll may be rotated and being mounted on a stud 17 operatively connected to the gearing 1 1. Said stud extends through a bearing 18 fixed on the right bracket 12. There is a sliding connection between the head 15 and the internal bore 19 'ofthe roll C which will'permit the latter to be moved to the left while the head 15 remains at rest. The matter thus far described may be of usual form and of itself forms no part of my present invention.

My invention relates to the mounting for the left hand end of the cloth roll and in carrying my improvements into eifect I provide the left stand 13 With'a bearing through which extends astud 81. The latter is free to rotate in the bearing, although it need not necessarily turn in the latter during the normal running of the loom. The stud is provided on its left end with an annular groove 32 which lies to the left of the hearing 30.

In order to determine the longitudinal position of the stud 31 relatively to the hearing I provide a locking member 33 having a rearwardly extending vertical portion 3% proportioned to enter the. groove 32. The rear end of the lock may be weighted as at 35 if desired while the forward end of the lock may have a depending handle portion 36 by means of which the lock may be raised. In order to support the member 33 1 provide a screw stud 37 which extends through an ear 38 preferably cast integral with the bearing 30. The screw stud is substantially parallel to the larger stud 31 and is held in adjusted position relatively to the ear 38 by right and left nuts 39 and L0, respectively. A shoulder 41 formed as part of the stud limits movement of the lock 33 to the right as viewed in Fig. 1 and a cotter pin 4-2 liniits movement of the lock to the left. It will thus be seen that the screw stud 3T acting through the lock 33 determines the longitudinal position of the main stud 31. Connection between the supporting stud 31 and the cloth roll C is established by a pivoted head which is journaled on a reduced end 51 of the stud 31 and is held between a shoulder 5?. on the stud 31 and a washer 53 held in place on the said stud by a screw 54;.

In operation the parts will normally be related as shown in Fig. 1, the gear 1% serving to give a progressive forward movement to the cloth roll C to wind up the cloth as the latter is woven. When it is desired to take a cut of cloth from the roll the handle 36 may be pushed rearwardly to move the lock about a stud 37 from the full to the dotted line position shown in 2. The stud 31 may then be moved to the left away from the cloth roll to move the head 50 from the bore 19. The cloth roll C may then be moved slightly to the left to disengage the same from the head 15 after which it may be entirely removed from the loom. lVhen the roll is to be inserted into the loom it will first be fitted over the head 15 and then the stud 31 will be moved to the right and the head 50 inserted into the bore 19. The, looking member 33 will then fall into the groove 32- to hold the stud 31 against longitudinal movement in either direction and the cloth roll will be correctly positioned.

I form the head 50 with a flange which may engage the end of the roll C and said head is perfectly square so as to have proper engagement with the square bore 19, the form of the head being designated in Fig. 5.

Cloth rolls vary slightly in length and the necessary adjustments may be afforded by means of the stud 3'7. The nuts 39 and 1:0 may be loosened and the stud turned either toward or away from the cloth roll so as to place the locking member 33 at ditferent positions relatively to the axis of the stud 31. The nuts may then be tightened and the lock will serve to hold the stud 31 in proper position.

From the foregoing it will be seen that l have provided a stud which is slidable and also rotatable in a bairing fixed relatively to the loom, the stud being provided with a groove to receive a locking member which is effective to limit motion of the stud in opposite directions. By reference to Fig. 2 it will also be seen that the stud 37 is eccentric with respect to the stud 31 so that any tendency which the stud 31 when rotating might have to lift the lock 33 will be greatly reduced. I find that this feature of my invention is of particular value. I find also that when removing the cloth roll the lock 33 may be lifted and the stud 3'1. moved a slight distance to the left such as will bring that portion of the stud 31 which lies between the groove and the shoulder 52 under the locking member 33 to support the latter. The operator may then handle the cloth roll which will still be supported by heads 15 and 50 and move the cloth roll endwise t0 the left because of the fact that stud 31 is free to slide in the bearing 30.

Having thus described my invention it will be seen that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention and I do not wish to be limited to the details herein disclosed, but what I claim is:

1. In a loom having a cloth roll, a fixed stand, a bearing formed as part of said stand having an axis in substantial alignment with the axis of the cloth roll, an element rotatably and slidably mounted in the bearing and having provision for engagement with the cloth roll to support the latter, a screw stud having its axis substantially parallel to the axis of the bearing and cloth roll and movable relatively to the stand in the direction of its axis, and a lock supported by the stud and having engagement with the element to restrain longitudinal movement of the latter in the bearing.

2. In a loom having a cloth roll, a fixed stand having a slide bearing therein co-axial with the cloth roll, a supporting member slidably and rotatably mounted in the bearing and having provision for supporting one end of the cloth roll, said element having an annular groove formed therein, a lock to enter the groove to restrain longitudinal movement of the element, and a support for said lock movable in the "direction of the length of the cloth roll.

3. In a loom having a cloth roll, a fixed stand having a slide bearing co-axial with the cloth roll, a supporting stud slidable and rotatable in the bearing and having provision for supporting one end of the cloth roll, said stud having an annular groove formed therein, a screw stud mounted on the support and HARRY M.
