" In Great Britain November 19, 1936 invention relates to the driving of the spindles of spinning, twisting and like textile frames for jute, flex, hemp, .cotton 'and' other fibres, and is partlcularlyapplicable to the driving of ring spinning and twisting frames.

According to; the inv'entionpfor driving the spindles of such frames'there is employed at least one "endless flexible belt or rope of any desired section, hereinafter referred to for convenience as a rop'e which'is looped in a vertical plane, at one side only'of "a row of spindles, and the upper flight of which is pressed into driving engage ment with the wharves of the spindles by means of loaded jockey rollers, while'the lower flight is passed around atensioning pulley located between ends of the row of spindles. j

The rope'may be arranged to circulate around two pulleys disposed at opposite ends of the frame, one of said pulleys being the driving pulley and a drive being taken through speed reducing gearing from the other pulley to the drawing roller shaft of the frame, provision being made in the gear train for exchangeof pinions to permit variationof the speed of rotation of the drawingroller shaft. r

The invention is illustrated in the accompanying drawings in which Fig. 1 is a front elevation and Fig. l a. plan showing a spindle driving belt and belt-tensioning means of a spinning frame. Figs. 2 and 3 are elevations at right angles to one another showing a jockey roller arrangement for the belt. Figs. 4 and 5 are elevations at right angles to one another showing reduction gearing for transmitting power from the belt to the drawing roller shaft of the frame. Figs. 6 and '7 are elevations at right angles to one another showing a modified jockey roller arr.angement.=

Fig. '8 is an elevation and Fig. 9 a plan showing a further jockey roller arrangement.

Referring to Figs. 1 and 1 a'row of bobbin spindles l of which only a few are shown are driven by an endless rope 2 of which the upper flight is engageable with the wharves 3 of the spindles. The rope is trained around apulley 5 at one end of the frame and around a driving pulley 6 at the other end'of the frame, and its lower or slack flight is looped around an inclined fixed guide pulley l and a pulley 8 which roller 4 to maintain the rope 2 'indriving engagement with the respective 'wharve 3? ffI-he pivot-I3 is carried by abra'cket l5 located on 'the underside of the spindle rail lfi and embracing thespindle journal sleeve ll. An adjustable stop screw l8 on thelever l 2 isengageable with a stop IS on the bracket l5 whereby tolimit the--move-' ment of the roller 4'in rope-pressing direction.

As shown in *Figs. 4 and 5, the pulley! constitutes a driver for a-,-worm and worm-wheel speed reduction gear unit Zil which transmits power to the drawing roller shaft 2| of the frame. A sprocket 22 on the output shaft 'of-the reduc ti'on gear is wrapped by a chain 23 which also wraps a sprocket 24 which is unitary with a spur wheel 25 meshing with apinion 26on the draw-f PATENT OFF 1 5 I v ing roller shaft 2| -The sprocket 24 and" its spur wheel 25 are journalled on a stud on theupper end of an arm 21 which is angularly adjustable about the axis of the sprocket 22, the arrangement being such that the speed of rotation of the shaft 2| may bepvaried as required by the adoption at 25 and 2B ofspur wheels with the requisite numbers of teeth. 1

Figs. 6 and 7 show a modified form of jockey roller arrangement in which the jockey roller 4 is mounted on the upper arm 29 of a two-armed pedal lever fulcrumed at 30 and presenting at the lower end of its lower arm 3! a pedal 32. The roller 4 presses on the rope 2 under the action of a weight 33 attached to a cord 34 trained over a pulley 35 and connected, through the medium of a tension spring 38, with a twin-link 36 pivotally connected at 3'! atits forward end to the arm 29, As will be understood, by actuation of the pedal 32 the roller 4 may be disengaged from the rope 2 in opposition to the action'of the weight 33, so as to interrupt the drive to therespective spindle I. When the pedal 32 is actuated, a brake member 38% is moved into engagement with the wharve 3 so as quickly to arrest rotation thereof.

Figs. 8 and 9 show a further jockey roller arrangement in which the jockey roller 4 is mounted on a slide 39 which is pulled in the direction to press the rope 2 against the wharve'3 by a weight 4ll'acting on the slide through the medium of a spring 4| For the purpose of temporarily holding the roller 4 clear of the rope 2 so as to interrupt the drive tothe spindle, there is provided a double-armed manually operable lever 42, 43 which is pivoted on the slide 39 coaxially with the roller 4 and which is rockable from the position shown in full lines into the position shown in dotted lines in Fig. 9, whereby'to hold the roller 4 clear of the rope 2. The inner arm 42 of the lever 42, 43 presents a cam-shaped part 44 and a concave part 45 so contrived that, when the lever is rocked from the full line position into the dotted line position, the cam-shaped part 44 engages the hub 46 of the wharve whereby the roller 4 is forced in the direction away from the wharve, and, when the part 45 engages the hub 46, the lever sets itself in the dotted line position and holds the roller 4 in inoperative position, until rocked in the reverse direction so as to re-establish the drive to the spindle. As will be understood, the spindle will be braked by the engagement of the lever with the hub 46.

The

tension spring

38 or 4| responds readily to vibrations set up by inequalities of the belt 2, so that these vibrations are not transmitted to the respective weights, and continuity of engagement of the jockey roller with the rope is ensured.

I claim:

1. A spinning, twisting, or like textile frame comprising a series of spindles, wharves on said spindles, an endless travelling rope looped in a vertical plane at one side of said row of spindles, a rope-driving pulley at one end of said row, a driven pulley at the opposite end of said row, said pulleys wrapped by said belt, a rope-tensioning pulley engaging the lower flight of said endless rope and located intermediate said driving and driven pulleys, jockey rollers urged in the direction to press the upper flight of said endless rope into engagement with said wharves, a drawing roller shaft, and gearing connecting said driven pulley with said shaft.

2. A spinning, twisting, or liketextile frame, comprising, in combination with a spindle rail, at least one, row of spindles journalled in said rail,

wharves on said spindles below said rail, an endless travelling rope for driving said wharves, said endless rope looped in a vertical plane at one side only of said row of spindles, a pulley at one end of said row of spindles, a driven pulley at the opposite end of said row of spindles, said pulleys wrapped by said endless rope, jockey rollers for pressing the upper flight of said endless rope into engagement with said wharves, suspended Weights for loading said jockey rollers, connections including springs between said weights and said jockey rollers, and a rope-tensioning pulley located between said first-mentioned pulleys and engaging the lower flight of said endless rope.

3. A spinning, twisting, or like textile frame, comprising, in combination with a spindle rail, at least one row of spindles journalled in said rail, wharves on said spindles below said rail, an endless travelling rope for driving said wharves, said endless rope looped in a vertical plane at one side only of said row of spindles, a pulley at one end of said row of spindles, a driven pulley at the opposite end of said row of spindles, said pulleys wrapped by said endless rope, jockey rollers for pressing the upper flight of said endless rope into engagement with said wharves, levers on which said jockey rollers are mounted, each of said levers operable manually to move the respective jockey roller in the direction away from the associated wharve, weights urging said jockey rollers in the direction to press the upper flight of said endless rope against said wharves, connections including springs between said weights and said jockey rollers, and a rope-tensioning pulley located between said first-mentioned pulleys and wrapped by the lower flight of said endless rope.
