Improvements in or relating to Mules and Twiners.
I, ROBERT WOOD, Secretary to the Firm of Emmott & Co. Limited of 2 New
Bridge Street Manchester, in the County of Lancaster, Printers and Publishers
(a communication from abroad by Arthur Henry Bellringer of Almelo, Holland,
Mill Manager) 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 improvements in the carriage bearers or arms of self-
acting mules or twiners, the object being to so construct these bearers that the
carriage or slide which they support may be drawn out and in with greater case and
uniformity than has hitherto been the case.
Hitherto the bearers referred to have been constructed with necks or bearings at
each end of an inverted U-shape into which the axles of the carriage which have
been placed. Owing to this construction a great amount of friction was set up
between the axles and the bearings, which frequently caused the carriage or slide
This
to have an
uneven or jerky motion during its traverse to and fro.
uneven motion was especially felt at the commencement of the "draw" in both
directions.
In order to obviate these defects I have constructed the bearers or arms with
what I might term elongated bearings so arranged that the bearers have a
sliding or rolling action on the axes of the carriage wheels.
My invention will be fully described with reference to the accompanying
drawings in which
Fig. 1 is an elevation of a carriage bearer constructed according to my invention,
whilst Figs. 2 and 3 show modifications in points of detail.
In carrying out my invention I make the arms A much longer than usual or at
any rate so alter their construction that long bearings a can be formed on their
underside. I prefer also to make the axles of the carriage wheels B much smaller
in diameter than those at present in use and of steel instead of cast iron. The axles
are shown occupying a position about midway of the elongated bearings, a position
which they would occupy when the carriage was about the middle of the draw. It
must, however, be understood that when the carriage is say at the end of the inward
run the axle of the back wheel would be against the inner end of the bearing whilst
the axle of the front wheel would be against the outer end of the front bearing.
These positions would be reversed when the carriage was at the end of the outward
stretch.
It will be seen from the drawings that the axles of the wheels are continually
changing their position during the traverse of the carriage in both directions, and
that little or no friction can occur between the moving surfaces, consequently the
carriage is moved much easier and with greater regularity than is possible under the
old construction of bearer. The length of the bearings will bear a certain relation to
the length of the stretch of the carriage and to the diameter of the carriage wheels
and axles thereof.
In some cases it may be advisable to insert small rollers a pulleys or the like at
each end of the bearings, as shown in Fig. 2 in order to reduce any friction which
may be set up at these points. Then again the length of the bearings may be
arranged to be alterable at one or both ends by the use of an adjustable collar Cas
shown in Fig. 3.
I would also have it understood that to prevent any possibility of the carriage
wheels twisting out of line the underside of the bearings may be made convex or
concave, or be provided with a strip projecting from the main body of the bearing

page_text: surface, corresponding concave, convex or grooved portions being formed on the
carriage wheel axles. Or in place of such arrangements the carriage bearer
may be so formed at the inner ends of the fork that the rims of the wheels can be
kept within proper limits.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed (as communicated to me
by my foreign correspondent) I declare that what I claim is :-
1. A bearer for the carriage or slide of a mule or twiner constructed with
elongated bearings substantially as and for the purposes described.
2. A bearer for the carriage or slide of a mule or twiner constructed and arranged
substantially in the manner shown by either Figs. 1, 2 or 3 of the accompanying
drawings.
