The roller 4 presses on the rope 2 under the action 30. 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 pivot gearing for transmitting power from the belt to ally connected‘ at 3'! at‘its forward end to the the drawing roller shaft of the frame.

The rope is trained around apulley 5 rangement in which the jockey roller 4 is mounted at one end ‘of the frame and around‘ a driving on a slide 39 which is pulled in the direction to 45 ; pulley 6 at the other end'of the frame, and its press the rope 2 against the wharve'3 by a weight lower or “slack” flight is looped around an in 4ll'acting on the slide through the medium of a ‘ at right angles to one another showing reduction . clined ?xed guide pulley ‘l and a pulley 8 which is pulled in rope-tensioning ‘direction by a weight 50 10 connected thereto by a rope ll. As shown in Figs. 2 and 3; the rope 2 is pressed spring 4|}. For the purpose of temporarily hold ing the roller 4 clear of the rope 2 so as to inter rupt the drive to‘the spindle, there is provided 50 a double-armed manually operable lever 42, 43 into driving engagement with each wharve 3 by which is pivoted on the slide 39 coaxially with ‘ means of a jockey roller 4 carried by a yoke lever the roller 4 and which is rockable from the posi tion shown in full lines’ into the position shown l2 depending from a pivot l3 and in?uenced by tension springs l4 in the direction to cause the in dotted lines in ‘Fig. 9, whereby'to hold the 2,, roller 4 clear of the rope 2. 2,131,896 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 posi 10 tion and holds the roller 4 in inoperative posi tion, 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. 15 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 engage 20 ment 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, 25 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 ?ight of said endless rope and located intermediate said driving and 30 driven pulleys, jockey rollers urged in the direc tion to press the upper ?ight of said endless rope into engagement with said wharves, a drawing roller shaft, and gearing connecting said driven 35 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, m wharves on said spindles below said rail, an end less 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 in 10 cluding springs between said weights and said jockey rollers, and a rope-tensioning pulley lo cated between said ?rst-mentioned pulleys and engaging the lower ?ight of said endless rope. 3. A spinning, twisting, or like textile frame, 15 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 end less travelling rope for driving said wharves, said endless rope looped in a vertical plane at one side 20 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 ?ight 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 includ ing springs between said weights and said jockey rollers, and a rope-tensioning pulley located be tween said first-mentioned pulleys and wrapped 35 by the lower ?ight of said endless rope. _ O.
