Complete Specification Left, 23rd Jan., 1890-Accepted, 1st Mar., 1890
PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Driving the
Spindles and Regulating the Drag of Bobbins on Roving and
Drawing Frames, also Applicable to Spinning and other
Machinery.
We EDWIN JAMES OATES, ARTHUR DONALD OATES, Worsted Spinners, and
WILLIAM EARNSHAW, Manager, all of Ryburne Mills, Halifax in the county of
York, do hereby declare the nature of this Invention to be as follows :-
--
We drive each two spindles with a band from their wharles, to the underside of a
self adjustable tension pulley, and over the top of the driving pulley on the driving
shaft. The tension pulleys are carried on studs upon which they have considerable
play laterally, the said stud is carried in the slot of a pivotted lever, in which they
are each adjustablo, the boss of the brackets aro bored at such an angle that the levers
are not at right angles to the rod upon which they are carried, or the levers may be
cast not at right angles to their bosses.
By the above arrangement there is no slipping of the bands, there being no slack
or too tight bands, also the frames require comparatively little power to drive them.
Under the roving or other bobbins, to regulate the drag, upon the lifter rail is
placed one or more cloth washers, and above the said washers, and under the bobbin
bottom I place a metallic dished washer, with its dished edges working against the
bobbin bottom, and its face upon the cloth washer, by this means I obtain an uniform
drag, and the dished plates are very durable and cleanly, and are not liable to stick to
the bobbin bottoms when doffed, and so do not become lost or damaged.

COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Driving the
Spindles and Regulating the Drag of Bobbins on Roving and
Drawing Frames, also Applicable to Spinning and other
Machinery.
We EDWIN JAMES OATES, ARTHUR DONALD OATES, Worsted Spinners, and
WILLIAM EARNSHAW, Manager, all of Ryburn Mills Halifax in the County of York,
do hereby declare the nature of this Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
Fig. 1. is a front elevation of our driving arrangement.
Fig. 2. is a plan of Fig. 1. showing four spindles.
Fig. 3. shows our arrangement for regulating the drag upor ving and drawing
frames and the like.
Fig. 4 is a plan of metallic washer N.
We drive each two spindles A A, with a band B, from their wharles C, to the
underside of. a self-adjustable tension pulley 1), and over the top of the driving
pulley E, on the driving shaft F.
The tension pulleys D are carried on studs G, upon which they have considerable
play laterally, each of the said studs G, is carried in the slot H of a pivotted lever J,
in which they are each adjustable.

page_text: The bosses of the brackets or levers J, are preferably bored at such an angle that
the levers are not at right angles to the rod F upon which they are carried or the
levers may be cast not at right angles to their bosses: the tightness of the bands B is
regulated by the weights K, upon the lever J:
Or the tension pulley instead of being fixed upon a lever, may be fixed upon a
forked bracket suspended or attached to any convenient part of the machine.
By the above arrangement there is no slipping of the bands,, there being no slack,
or too tight bands, also the frames require comparatively little power to drive them.
Under each of the roving or other bobbins K, to regulate the drag upon the lifter
rail L, is placed one or more cloth wasliers M, and above the said washers, and under
the bottom of the bobbins, we place a metallic dished washer N with its dished edges
working against the bobbin bottom, and its bottom face, upon the cloth washers M.
By this means we obtain a uniform drag, and the dished plates are very durable
and cleanly, and are not liable to stick to the bobbin bottoms when doffed, and so do
not become lost or damaged, besides keeping the cloth washers clean, and therefore
making the same more durable.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that. what we
claim is :-
1. Driving two spindles with one band, from the wharles C, to the underside of the
regulating tension pulley D (upon the studs G, adjustable in slots H) then over the
driving pulley E, substantially as shown and described.
2. Regulating the tension or drag upon the roving thread and yarn, by means of
the metallic washers N, and cloth washers M, substantially as shown and described.
