PROVISIONAL SPECIFICATION.
Improvements in or relating to Mules and Twiners.
We, ROBERT HARDMAN of 132 Tonge Moor Road, Machine Foreman, and
JOSEPH TOOTELL of 237 Tonge Moor Road, Mill Manager, both of Tonge near
Bolton in the County of Lancaster, do hereby declare the nature of our said
invention to be as follows:-
This invention refers to improvements in or relating to mules and twiners and has
for its object that of improving the movement of the carriage, for the purpose of
reducing friction, power, and the strain on driving bands or their equivalents for
operating the same. This we effect by providing the carriage arms with suitable
bearings to receive one or more centres on which are mounted metallic bowls
or rollers of any convenient diameter to work in conjunction with the carriage bowl
centre. The whole may be enclosed in a metallic box or end secured to the end of
the carriage arm; each bearing being sufficiently long to prevent the same being
displaced in the to and fro movements of the carriage. This invention is so
constructed as to be applicable to existing carriage arms.
If desired each metallic
box or end may be constructed to hold a series of bowls or rollers to form what are
known as ball-bearings, the same being enclosed and secured therein in any
convenient manner. Suitable arrangements are provided to allow of the bearings
being thoroughly lubricated.

We, ROBERT HARDMAN of 132 Tonge Moor Road, Machine Foreman, and.
JOSEPH TOOTELL of 237 Tonge Moor Road, Mill Manager, both of Tonge near
Bolton in the County of Lancaster, do hereby declare the nature of our said
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 refers to improvements in or relating to mules and twiners and has
for its object that of improving the movements of the carriage, for the purpose of
reducing friction, power, and the strain on driving bands or their equivalents for
operating the same. This we effect by providing the carriage arms with suitable
bearings to receive one or more centres on which are mounted metallic bowls or
rollers of any convenient diameter to work in conjunction with the carriage bowl
centre. The whole may be enclosed in a metallic box or end secured to the end of

metallic box or end may be constructed to hold a series of bowls or rollers to form
what are known as ball bearings, the same being enclosed and secured therein in
any convenient manner. Suitable arrangements are provided to allow of the
bearings being thoroughly lubricated.

page_text: Fig. 1 is a sectional elevation of a mule carriage with our improvements
applied.
Fig. 2 is an enlarged view of end of carriage arm.
Fig. 3 is a side view of elongated bearing provided with two metallic bowls or
rollers, and
Fig. 4 is a side view showing three metallic bowls or rollers.
In all the figures the same letters are employed to indicate corresponding
parts.
A is the mule carriage; B the spindle; C the cylinder; D the driving band;
E the carriage arm, and F the carriage wheels or pulleys. The carriage arms E
are provided with the metallic boxes or ends G carrying the bearings H in which
are mounted the centres I. On the latter are secured the metallic bowls or rollers J
of any convenient diameter to work in conjunction with the carriage bowl
centres K. By thus mounting the carriage arms E on the centres K the friction of
the same is reduced to the least possible amount during the inward and outward
movements of the said carriage. The metallic boxes or ends G may be constructed
as shown in Fig. 3, wherein the bearing H of the metallic box or end G rests or sits
on the centre K of the carriage wheel or pulley F. In this case the bowls or
rollers J are mounted in the bearings H and so disposed as to allow of the elongated
bearing having a sliding or rolling action on the centres K of the carriage wheels,
thereby allowing of the to and fro movements of the carriage being effected with
greater ease and uniformity than hitherto. To reduce friction to the least possible
amount we construct the metallic boxes or ends G of the carriage arms E as shown
in Fig. 4, wherein we employ three bowls or rollers J. In this case the end G is
fitted with the upper bowl or roller J which sits on the carriage bowl centre K.
On examining Figs. 3 and 4 it will be seen that the axles K of the carriage
wheels F change their position during the traverse of the carriage A in both
directions and the friction is reduced to the least possible amount, consequently the
mule carriage A is operated much easier and with greater regularity than is possible
under present arrangements. For the purpose of lubricating the bowl or roller I
and the carriage bowl or centre K the boxes or ends G are provided with the
holes M to receive oil or other lubricant.
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:
In combination with the arms and wheels or pulleys employed for carrying the
carriages of mules and twiners the use and application of the bowls, rollers
or pulleys I operating in the bearings H, for the purpose of reducing the power to
actuate the said carriage and minimise the strain on gearing for driving same
during the inward and outward movements, applied and operating substantially as
described and as illustrated in the annexed drawings.
