p Claims. (Cl. 242-544) This invention concerns a device for supporting and moving the ball roll of a balling head of single or double pin-field gill boxes for combing and drawing of natural and artificial fibers.

It is an object of the present invention to provide a baller in which the ball roller or winding spool is maintained inconstant engagement with the driving roller or rollers.

It is another object of the present invention to provide a baller in which the'mechanism by means of which the ball roller is maintained in constant engagement with the driving roller or rollers is of very simple and rugged construction.

The objects of the present invention also include the provision of a baller capable of accomplishing the above objects, which baller is further adapted to be so manipulated as to make the removal of a wound ball very easy.

With the above objects in view, the present invention mainly resides in that improvement in a baller which comprises a ball roller adapted to have a sliver wound thereon, mounting means for mounting the ball roller for rotation about a first axis and for movement along a path lying in a plane containing this first axis, a driving roller mounted for rotation about a second axis parallel to the first axis, the driving roller being so positioned as to be adapted to be engaged by the sliver wound upon the ball roller, and yielding biasing means connected to the mounting means for continuously urging the ball roller for movement along the path toward the driving roller so that the same continuously engages the sliver wound upon the ball roller.

The present invention is described with reference to the enclosed sketch and both the description and the sketch are not restrictive but are merely given as an example.

The only figure of the sketch is the side elevation of the preferred embodiment of the device.

Referring now to the drawing, A shows the frame of the machine supporting the sloping rod .1 which slides axially. The sloping rod has at its end the horizontal arbor 2 carrying the ball roll 3. Rod 1, which cannot rotate because of the longitudinal key 4, has at the bottom a rack 5 meshing with a toothed wheel 6 supported by the frame A of the machine. A chain or sprocket wheel 7, supporting the chain '8 is keyed on the axle of the wheel 6. One of the ends of the chain carries the weight 9, and the other end is fastened near the loose This pedal is pivotally mounted on the frame A by a suitable joint 1-2.

In the position shown in the sketch the weight 9 tends to rotate the wheels 7 and 6 in the direction of arrow X, and this, in turn, tends to move axially rod 1 in the direction of the arrow Y. Ball roll 3 is therefore pressed against winding or driving rolls 13 and the sliver 14 is normally wound on the ball roll 3. As the diameter of the ball increases, rod 1 is automatically moved in the opposite direction of arrow Y, this movement being counteracted .by the weight 9'.'

At the end of the winding operation, or in the event posite'to the one shown by the arrow X, and this, in

turn, will cause the rod 1 to move upwardly in the di-. rection opposite to the one shown by the arrow Y. Thus, when the arbor 2 is in the raised position, the ball. roll 3 may be removed, or, in the event of breakage of the sliver, the same may readily be knotted.

- A suitable detent arrangement is provided for maintaining the pedal, whenever desired, in depressed condition. In this way, the ball roll may be held in the up position without it being necessary for the operator continuously to hold the pedal down. Such detent arrangement includes a bell crank lever having a downwardly extending arm 15 and a generally horizontallyextending .ar'm-18 which extends in the direction of the pedal I l. The lower end of the arm 15 is formed with a nose 16 adapt'ed'to engage a cross piece 17, the arrangement of thelparts being such that when the pedal 11 is depressed, the lower end of the arm 15 will first cam past the cross piece 17 and upon, release of the pedal will engage this cross piece, thereby preventing upward movement of the pedal. Release of the detent means is effected by depressing the arm .18.

It is understood, of course, that the details of the device may vary without losing the present industrial protection.

In the claims:

1. In a ballet, in combination, a ball roller adapted to have a sliver wound thereon; mounting means for mounting said ball roller for rotation about a first axis and for movement along a path lying in a plane containing said first axis, said mounting means including a movable element movabe in the direction of said path; a driving roller mounted for rotation about a second axis parallel to saidfirst axis, said driving roller being arranged in said path and adapted to be engaged by the sliver wound upon said ball roller; yielding biasing means connected to said movable element of said mounting means for continuously urging said ball roller for movement along said path toward said driving roller so that the same continuously engages the sliver wound upon said ball roller; and control means operatively connected to said movable element of said mounting means for moving, whenever desired, said movable element and said ball roller along said path away from said driving roller against the action of said biasing means.

2. In a baller, in combination, a ball roller adapted to have a sliver wound thereon; mounting means for mounting said ball roller for rotation about a first axis and for movement along a path lying in a plane containing said first axis, said mounting means including a movable element movable in the direction of said path; a driving roller mounted for rotation about a second axis parallel to said first axis, said driving roller being arranged in said path and adapted to be engaged by the sliver wound upon said ball roller; yielding weight means connected to said movable element of said mounting means for continuously urging said ball roller for movement along said path toward said driving roller so that the same continuously engages the sliver wound upon said ball roller; and control means operatively connected to said movable element of said mounting means A taining said first axis, said mounting means including an elongated mounting element extending in the direction of said path; a driving roller mounted for rotation about a second axis parallel to said first axis, said driving roller being arranged in said path and adapted to be engaged by'the sliver Wound upon said ball roller; yielding weight means connected to said mounting means for continuously urging said ball roller for movement along said path toward said driving roller so that the same con-l tinuously engages the sliver wound upon said ball roller, said weight means including a toothed rack on said mounting element and extending in the direction of its, length, a gear mounted for rotation about a third axis and meshing with said toothed rack, a pulley also mounted for rotation about said third axis and rotatable with said gear, a cable power-transmittingly engaging said pulley, and a weight connected to said cable at one end thereof, said cable and weight being so arranged as to cause said pulley and consequently said gear to rotate about said third axis in such a sense as will cause said gear to move said rack and consequently said mounting element in that direction as will bring about movement of said ball roller along said path toward said driving roller; and moving means for moving, whenever desired, said ball roller along said path away from said driving roller against the action of said weight means, said moving means including control means connected to the opposite end of said cable for moving the same in a direction opposite to the direction in which said weight tends to move said cable, whereby a force may be applied to said cable in opposition to the force exerted by said weight, thereby causing said pulley together with said gear to rotate about said third axis in the opposite sense thus causing said gear to move said rack and consequently said mounting element in that direction as will bring about movement of said ball roller along said path away from said driving roller.

4. The combination defined in'claim 3 wherein said control means include a foot pedal and foot pedal mounting means for mounting said foot pedal in such a manner that said cable is moved in opposition to the force exerted by said weight'when said foot pedal is depressed.

5. The combination defined in claim 4, and detent means operativelvassociated with said foot pedal for maintaining the same, whenever desired, in depressed condition, whereby said ball roller may, without foot depression of said foot pedal, be maintained insuch a position wherein the sliver wound upon said ball rolleli is out of engagement with said driving roller.
