of Dob Meadow Mill, Failsworth, in the County of Lancaster, Cotton Spinners,
do hereby declare the nature of this invention to be as follows:-
run in "
The object of this invention is to prevent the over-running of the mule carriage
and to ease the sudden shock to which the said carriage is liable, at each "
thereof, and to lessen the vibration thereof which occurs particularly at the ends
farthest from the headstock in consequence of the length of the carriage, and the
deflection to which these outward ends are liable, the sudden impact against the
rigid buffers or stops frequently causing a slight recoil of the carriage ends.
This shock affects the whole structure, and this sudden vibration has also the
effect of frequently breaking a number of the ends of the yarn and also of weaken-
ing the same at certain parts by the unequal strain or pull to which it is subjected
at each "
run in". of the carriage.
Our invention is intended to remedy these defects, and for this purpose we fix
at a convenient part of the floor near the outward end of the carriage, a rod, bar
or lever of say about five feet in length, one end being pivoted to a suitable bracket
on the floor, near the end of the stretch of the carriage and the other end is con-
nected by a coiled or other suitable spring (at about right angles to the rod) to a
bracket fixed to the floor. This rod bar or lever rests upon a bearing block at the
spring end thereof, and is held by the spring at a slight angle to the motion of the
carriage.
On the back (or other convenient part) of the carriage we fix a bracket carrying
a vertical pin on which is a loose bowl or roller, which is placed in such a position
as to be capable of coming in contact with the horizontal spring rod aforesaid.
Thus it will be seen that as the carriage commences its inward run, the bowl on the
hanging or projecting bracket comes in contact with the spring bar, or lever, and
gradually pushes it a little to one side, which thus has the effect of a steady brake to
counteract, by means of the said spring, the over-running of the carriage, and so
prevents the sudden shock or vibration to which the carriage has hitherto been
liable.
Of course it will be necessary to place this arrangement at each of the outer
ends of the carriage.

We, YOUNG DUNKERLEY, MAYALL DUNKERLEY, and GLADSTONE DUNKERLEY, all
of Dob Meadow Mill, Failsworth, in the County of Lancaster, Cotton Spinners,
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:-
The object of this invention is to prevent the over-running of the mule carriage
and to ease the sudden shock to which the said carriage is liable, at each "run in
thereof, and to lessen the vibration thereof which occurs particularly at the ends
farthest from the headstock in consequence of the length of the carriage, and the
deflection to which these outward ends are liable, the sudden impact against the
rigid buffers or stops frequently causing a slight recoil of the carriage ends.
This shock affects the whole structure, and this sudden vibration has also the
effect of frequently breaking a number of the ends of the yarn and also of weaken-
ing the same at certain parts by the unequal strain or pull to which it is subjected
at each run in" of the carriage.
Our invention is intended to remedy these defects, and the same will be readily
understood from the following description on reference to the accompanying
drawings.
Fig. 1 is a general plan view indicating the mule carriage A and our improve-
ment applicable thereto.
Figs. 2, 3, and 4 are respectively front view, side view, and plan view of detached
parts drawn to a larger scale.
On Fig. 1 B is the position of the headstock and C that of the creel of the mule.
We fix at a convenient part of the floor near the outward end or other con-
venient part of the carriage A, a rod, bar or lever a of say about five or six feet
in length, one end being pivotted to a suitable bracket a on the floor, near the
end of the stretch of the carriage; and the other end is connected by a coiled or
other suitable spring or springs 6 (at about right angles to the rod a) to a bracket b
fixed to the floor. This rod bar or lever a rests upon a bearing block 6 at the
spring end thereof, and this block may be in one piece with the bracket b¹, and
the rod or lever a is held by the spring at a slight angle to the motion of the
carriage, a stop 63 being provided on the block 2 to prevent the lever or bar a
from being pulled off the said block 2 by the spring b.
On the back (or other convenient part) of the carriage A we fix a bracket c
carrying a vertical pin c¹ on which is a loose bowl or roller d, which is placed in
such a position as to be capable of coming in contact with the horizontal spring
rod a aforesaid.
Thus it will be seen that as the carriage A commences its forward run, the
bowl d on the hanging or projecting bracket comes in contact with the spring bar
or lever a and as it travels along the path shown by the line X-X seen on Fig. 1
gradually pushes the said rod bar or lever a little to one side, which thus has the
effect of a steady brake to counteract (by means of the said spring or springs b)
the over-running of the carriage A, and so prevents the sudden shock or vibration
to which the carriage has hitherto been liable.
Of course it will be necessary to place this arrangement at or near each of the
'outer ends of the carriage.
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:-
The combination of a bracket and, bowl on the carriage and a long spring rod

page_text: bar or lever pivotted to the flooring substantially as and for the purpose herein-
before described.
