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.

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.
