PROVISIONAL SPECIFICATION.
Improvements in Spinning Mules and Twiners.
We, JOHN WAIN, Junr., and BROWN WAIN, both of 16, Duncan Street,
Longsight, Manchester, in the County of Lancaster, Mechanics, do hereby
declare the nature of this invention to be as follows:-
This invention relates to an improvement in spinning mules and twiners. The
object of this invention is to reduce friction in the bearings which support the shaft
that carries the tin rollers. In the accompanying drawing Fig. 1 is an end view
and Fig. 2 a plan of part of a mule carriage with our invention.applied. For the
purpose herein before named we mount a friction bowl or roller b on a bracket
as a that is affixed to an extended portion of the frame c upon which the bracket d
which carries the tin rollers is affixed, and in proximity to the tin roller shaft g
so that the periphery of the aforesaid bowl or roller will be in contact with said
tin roller shaft. The bearing m is adjusted in a position that the roller b will press
against the shaft g and prevent said shaft being drawn into binding contact with
the bearing by the action of the bands that communicate motion to the
spindles q. The diameter of the roller b is such as to cause the speed of rotation to
be considerably less than that of the shaft g by which said roller is actuated,
therefore the speed of the spindle t which carries said roller is also less.
The shaft g will run perfectly free in the bearings as the friction is transferred
therefrom to the slowly revolving spindle t. By these means friction is greatly
reduced and may be further diminished by the introduction of balls in a race
formed at v to form a bearing for the spindle t.

Improvements in Spinning Mules and Twiners.
We, JOHN WAIN, Junior, and BROWN WAIN, both of 16, Duncan Street,
Longsight, Manchester, in the County of Lancaster, Mechanics, 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 invention relates to an improvement in spinning mules and twiners. The
object of this invention is to reduce friction in the bearings which support the shaft
that carries the tin rollers. We attain this object by the means hereinafter described

page_text: and as shown in the accompanying three sheets of drawings in which Fig. 1 is a side
view and Fig. 2 a plan of part of a mule carriage with our invention applied. Figs. 3
and 4, and Figs. 5 and 6, are respectively side views and plans of modifications of
the same invention.
In these views similar letters refer to similar parts.
For the purpose herein before named, we mount a friction bowl or roller b on a
bracket as c that is affixed to a frame d extending between the front and back of
the mule carriage a and upon which the bracket f which carries the tin rollers e
is also affixed. The friction bowl b is placed in proximity to the tin roller shaft t so
that the periphery of said bowl or roller will be in contact therewith. The bear-
ing m is adjusted in a position that the roller b pressing against the shaft t will
prevent said shaft being drawn into binding contact with the bearing j by the
action of the bands that communicate motion to the spindles q. The diameter of
the roller b is such as to cause the speed of rotation to be considerably less than that
of the shaft by which said roller is actuated, therefore the speed of the spindle
which carries said roller is also less. The shaft will run perfectly free in the
bearings as the friction is transferred therefrom to the slowly revolving spindle g.
By these means friction is greatly reduced and may be further diminished by the
introduction of bowls v or balls as shown in the modifications represented on
Sheets 2 and 3 of the accompanying drawings. Figs. 3 and 4 represent balls v.
placed so as to form a bearing for the tin roller shaft t and Figs. 5 and 6 show a
bowl for the like purpose, with an oil trough for lubricating said bowl.
The relative positions of the tin rollers with the spindles may be regulated by the
set screw and horizontal adjustment is obtained by means of the screw .. The
top and bottom spindle boxes h h or other parts of the mules and the position
of the spindles remain unchanged.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1st. In spinning mules and twiners the use of bowls or rollers for relieving or
reducing friction in the bearings of the tin roller shaft by said bowls or rollers
being fitted so as to resist the forward pressure of the tin roller shaft caused by the
drag of the spindle cords, substantially as herein before described.
2nd. In spinning mules and twiners the use of bowls or rollers employed as
bearings for the tin roller shafts and for resisting the forward pressure in the
bearings of said shafts substantially as and for the purpose herein before described.
3rd. In spinning mules and twiners the application of a bowl or roller as 6 for
resisting the forward pressure of the tin roller shaft on the bearings and in
combination therewith the use of balls as v upon which said tin roller shaft may
rest, substantially as and for the purpose herein before described.
