SUPPORT FOR BOBBIN HGLDEBS.

Application filed October 14, 1924. -Serial No. 743,604.

To all whom it may concern:

Be it known that I, ALFRED DELERUE, a citizen of the Republic of France, and residing at Roubaix, Nord Department, No. Rue Pellart, in the Republic of France, engineer, have invented certain new and in Supports for Bobbin Holders, of which the following is a specification.

The present invention has for its object improvements in supports for bobbin holders 'which are intended to improve the operation of the'same while providing in a reliable and durable manner for the entire freedom of rotation of the bobbin holders in I their supports.

Devices of this kind have been proposed in which the bobbin-holder is disposed between two balls which are mounted loosely within casings carried upon springs in such a manner that the said balls are caused to bear in an elastic manner upon the ends of the bobbin holder and serve as pivots for the rotation.

In the known devices of this kind the bobbin might leave the U-shaped support when the formation of the bobbin requires a considerable pressure between the actuating element and the bobbin holder; but this could not happen with the use of a spindle traversing the bobbin.

The device according to the present invention serves to provide for the arrangement of the bobbin holder between the balls of the bearing, the same safety in maintenance as is afforded by a spindle travers ing the bobbin, while eliminating all axial play, which is impossible to obtain bythe use of a spindle so arranged.

For this purpose the ball-bearings of the bobbin holder are secured to flexible strips mounted upon a rigid frame which is suitably recessed in order to allow the elastic ilexion of said strips in the direction of the axis of the bobbin holder; the position of one of the said strips is secured by means of a locking member mounted on the support, such as preferably a set screw, wnilst the other strip may be secured in position by a suitable locking member mounted on the support so as to be capable of being moved away at will.

In these conditions, the bobbin holder is rigidly maintained in the lengthwise direction between the said locking members when rotating, but can at the same time be removed with facility after releasing the said locking member.

The appended drawing shows by way of example a constructional formof the device according to the presentinvention. Figs. 1 and 2 are respectively a side and a front elevation.

Figs. 3 and 4t are like views showing the mounting and dismounting of the bobbin holder. I

1 is the bobbin holder tl-shaped support in which are provided the two recesses 3 and 4c. The bobbin holder 2 is mounted upon two ball-bearings 3 and 4:,which are respectively secured to the flexible strips 6 and 8. The strip 6 is pierced with" apertures 15 and 16, and the strip 8 with the apertures 17 and 18. The apertures 15 and 16 have therein the respective screws 5 and 7 maintaining the strip 6 upon the support 1; the aperture 17 has disposed therein. the screw 9 connecting the strip 8 to the support 1. Theaperture 8 has disposed therein with easy friction the jour nal 10 which is secured to the support 1;

In these conditions, the bearings 3 and a can move solely on the centre line of the bobbin holder 2 A maintaining member 11 is mounted upon the journal 10 and is loosely movable on the axis of the said journal so as to engage its extension '19 at will between the rear face of the hearing 4 and the inner face of the recess 13. The end ofthe extension 19 is preferably narrowed to some extent for its easy entrance between the bearing and the support. A screw which is mounted in the support 1 cooperates with the inner end of the bearing 3 and provides for the accurate adjustment of the spacing of the balls in the bearings 53 and a.

. It is observed that when the said bobbin holder is placed between the balls oft-he bearings 3 and a and the said maintaining member 11 when occupying its proper position, it will be impossible for the said bobbin holder to assume, relative to the sup port 1, any other movement than a movement of rotation about its axis.

The rigidity of the said support is preferably made complete by the addition of corner pieces a0 and 41. It is observed in Figs. 8 and at that the recess 13 allows the bearing t to recede by a sutiicient amount in order that the bobbin holder 2 may be released with facility. The thickness of the extension 19 of the member 11 is such that when said member is engaged between the end of the bearing 4 and the inner face of the recess 13, the device is suitably pressed together, the screw 12 being employed for the pre liminary adjustment. The apertures in the strips 6 and 8 have a suflicient length in order that by unscrewing the screws 5, 7 and 90ne mayregulate the position of the axis of the bobbin with respect to the pivoting axis of the support.

In the said device, the bobbin holder mounted on ball bearings can be held with as great rigidity as can be obtained by the use of a traversing spindle. The insertion and removal of the bobbin are facilitated and all pressure of the bearing balls upon the spindle can be eliminated at will, as well as all lengthwise motion of the bobbin holder, thus preventing all crossing upon the bobbin such as isoccasioned by such motion. It enables the combination in the same device of the advantages due to the rotation of the bobbin holder upon thrust ball bearings and those due to the, use of the transverse spindle; on the other hand, when a bobbin holder is again inserted it will oc cupy exactly its original position. It is now feasible to wind up an unfinished bobbin or a new bobbin with new layers of yarn without any inconvenience.

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

1. In a support'for bobbin-holders, the combination of an axially bored bobbinholder, a ball adapted to engage the opening of the bore of the bobbin holder at each of its ends, two ball bearings adapted to receive each the said ball respectively, flexible strips adapted to support the said ball bearings, and two locking members mounted on the support, adapted to stop the said ball bearings against the axial thrusts towards the exterior, one of these locking members being movable transversely so as to allow one of the said ball bearings to move away from the bobbin holder when the latter is to be removed from the support.

- 2. In asupport for bobbin holders, the combination of an axially bored bobbinholder, a ball adapted to engage the opening of the bore of the bobbin holder at each of its ends, two ball bearings adapted to receiveieach the said ball respectively, flexible strips adapted tosupport'the said ball bearings, and two locking members mounted on the support, adapted to stop the said ball bearings against the axial thrusts towards the exterior, one of these locking members being pivoted upon the said support so as to be able to be introduced into the interval between the support and the respective bearing so as to rigidly stabilize the latter and so as to be able to be removed at will from the said interval so as to liberate the said bearing in order to allow the removal of the bobbin holder.

3. Ina support for bobbin holders, the combination of an axially bored bobbin holder, a ball adapted to engage the opening of the bore of the bobbin holder at each of its ends, two ball bearings adapted to re ceive each the said ball respectively, fiexible strips adapted to support the said ball bearings and two locking members on the support, adapted to stop the said bearings against the axial thrusts towards theexterior, one of these locking members being movable transversely so as to allow one of the said ball hearings to move away'froin the said bobbin holder when the latter is to be removed locking member being adjustable in the direction of the axis of the bobbin holder so as to adjust the clamping of the balls of the bearings against the bobbin holder.

4. In a support for bobbin holders, the combination of an axially bored bobbin holder, a ball adapted to engage the opening of the bore of the bobbin holder ateach of its ends, a ball bearing adapted to receive said ball, flexible strips adapted to support said strips,a journal upon said support and adapted to engage said opening, a screwadapted to adjust the position of one of the strips, a locking member adapted to rotate freely around the axis of the said journal, said locking member being provided with an extension adapted to be engaged between the baclr side of the ball bearing placed at this end of the bobbin holder and the inside of the said support.

In testimony that I claim the foregoing as my invention, I have signed my name.
