PROVISIONAL SPECIFICATION.
Improvements in Spinning and Doubling Spindles.
We, EDMUND TWEEDALE, SAMUEL TWEEDALE, and JOSEPH SMALLEY,
Machinists Castleton, near Manchester do hereby declare the nature of this invention
to be as follows:-
This improvement relates to the arrangement of the brake part of self contained
spindles used in spinning & doubling machines for cotton and other fibrous materials,
and consists in the method of hinging the brake to the front part of the bolster
carrier or the tilting lever described in Specification No. 2799 for the year 1882.
In carrying out our invention we form ears or projections on the bolster carrier
or on the tilting lever above mentioned & also on the brake part. Holes_are
formed in these projections for the reception of a pin to act as fulcrum. This
fulcrum for the brake is so arranged that when the pressure is relieved after
stopping a spindle, the weight of the brake tends to cause it to fall away from the
wharve. To prevent it falling too far away from the wharve we provide a stop
so as to limit its movement. That portion of the brake that comes in contact with
the wharve we prefer to cover with leather or some such material & we shape it to
fit the curve of the wharve. To secure this material to the brake we form a vee
or dovetailed groove for its reception and into which it is driven. The flange of
the wharve is made wider than usual to present extra surface to the brake.

ninety-three.

Improvements in Spinning and Doubling Spindles.
We, EDMUND TWEEDALE, SAMUEL TWEEDALE, and JOSEPH SMALLEY,
Machinists, Castleton, near Manchester, 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:-
This improvement relates to the arrangement of the brake-part, of self contained
spindles used in spinning and doubling machines for cotton and other fibrous materials,
and consists in the method of hinging the brake to the front part of the bolster
carrier or the tilting lever described in Specification No. 2799 for the year 1882.
In order that our improvements may be more clearly understood we will make
reference to the accompanying sheet of drawings, wherein Figs. 1 and 2 are
elevations of self contained spindles to which our improvements are applied, and in
this case we have shewn the application of a brake A to the ordinary tilting lever B.
This tilting lever is provided with a projection or lug C and it fits between two
projections or ears D on the lower part of the brake, the two parts being connected
together by a pin a which forms a fulcrum for the brake to work upon. When it
is required to apply the brake to the wharle E, it is forced against the said wharle
as shewn in dotted lines in Fig. 2, but when pressure is removed off the brake, the
latter falls away from the wharle by its own gravity, the fulcrum a being so
centered as to permit the brake to leave the wharle self actingly, but to prevent
[line 71

page_text: the said brake falling too far away from the wharle, a stop piece b formed by the
end of the projection C is employed after the manner of a knife joint. The brake
is provided with a piece of leather or other suitable material F which is shaped to
fit the curve of the wharle as shewn in plan view Fig. 3. Fig. 4 is a sectional
elevation of the brake, together with its adjoining part C to which it is hinged
projecting from the tilting lever.
Figs. 5 and 6 are also elevations of a self contained spindle, in this case the
application of a brake A is not shewn attached to the tilting lever, but to the base G
of the bolster. This brake is provided with crank pins c which are inserted into
ears or recesses formed in the underside of the base plate G, and these cranked
pins are inserted into their recesses before the base plate is secured to the spindle
rail H; as soon however as the cranked pins are inserted into the recesses they form
a fulcrum upon which the brake can work. This brake, like the preceding one,
falls away from the wharle by gravitation and it is prevented falling too far away
by the spindle rail upon which the lower part of the brake rests. Leather or other
material F is also driven into a recess formed in the brake as seen in Fig. 6 and
plan view Fig. 7.
We make the flange of the wharle deeper than formerly so as to present extra
surface to the action of the brake.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
Firstly. In self contained spindles having a tilting lever B, the connection
thereto of a hinged brake, constructed and operated substantially as described and
shewn in the drawings.
Secondly. In self contained spindles, the combination therewith of a brake,
-connected to the base of the bolster, constructed and operating in manner
substantially as shewn and described.
Deted this 5th day of June 1894.
