PROVISIONAL SPECIFICATION.
Improvements applicable to the "Mendoza" of Mules for Spinning
Cotton and other Fibrous Substances.
I SAMUEL NEWTON of 74 Kenyon Street Ashton-under-Lyne in the County of
Lancaster Machinist Manager, do hereby declare the nature of this invention to
be as follows:-
The object of this invention is to apply a safety motion to the "Mendoza" lever
of mules which shall ensure the raising of the said lever when the carriage has
run out in order to prevent damage in case the usual cam on the cam shaft fails
to act.
For this purpose I connect the "Mendoza" lever to a suitable bell crank or
equivalent lever pivotted to the frame of the headstock of the mule and I attach to
the lower end of this lever which hangs near the flooring a light rod which is
capable of sliding in suitable bearings in the direction of the movement of the
carriage and is provided with a collar boss or other projection.
Upon the carriage I fix a bracket in such a position that the above named rod
passes through an eye, slot, or fork, formed at or near the end thereof.
The collar boss or projection on this rod is so placed near the further end thereof
that as the carriage reaches the completion of its stretch the bracket which moves
along the rod comes in contact with the said collar boss or projection and carries
the rod with it for a short distance, and thus by means of the connection at its
other end with the lever attached to the "Mendoza" lever, the carriage itself will
raise the latter and ensure the stopping of the back shaft in case the ordinary cam
on the cam shaft fails, from any cause, to act.
Dated this 19th day of September 1891.

COMPLETE SPECIFICATION.
Improvements applicable to the "Mendoza" of Mules for Spinning
Cotton and other Fibrous Substances.
I SAMUEL NEWTON of 74 Kenyon Street Ashton-under-Lyne in the County of
Lancaster, Machinist 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 :-
The object of this invention is to apply a safety motion to the "Mendoza " lever
of mules which shall ensure the raising of the said lever when the carriage has
run out in order to prevent damage in case the usual cam on the cam shaft fails
to act.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the annexed sheet of drawings and the following explanation thereof.
Fig. 1 on the drawing is a side elevation and Fig. 2 a plan view of so much of
the headstock of a mule as is necessary to illustrate the application of my invention
thereto.
ais part of the framing of the headstock, b is the back shaft, c the roller shaft,
d the spur gearing for driving the back shaft and e the "Mendoza " lever.
For the purposes of my invention I connect the "Mendoza" lever e to a suitable
bell crank or equivalent lever ƒ pivotted to the frame of the headstock, and I

page_text: attach to the lower end of this lever which hangs near the flooring a light rod g
which is capable of sliding in a suitable bracket which is attached to the floor in
the direction of the movement of the spindle carriage (part of which is shown at i)
and this rod g is provided with a collar, boss or other projection k.
Upon the carriage I fix a hanging bracket in such a position that the above
named rod g passes through an eye, slot, or fork formed at or near the end
thereof.
The collar, boss, or projection k on the rod g is so placed near the further end
thereof that as the carriage i reaches the completion of its stretch the bracket /
thereon which moves along the rod y comes in contact with the said collar, boss, or
projection and carries the rod g with it for a short distance, and thus by means
of its connection at the other end with the bell crank lever fattached to the
Mendoza" lever e it will raise the same into the position shown by the dotted
lines in Fig. 1 thus throwing the spur wheels d out of gear and stopping the
revolution of the back shaft b by the motion of the carriage itself if the ordinary
cam should fail from any cause to act.

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
Connecting the "Mendoza" lever of a mule by means of a bell-crank or
equivalent to a sliding rod (mounted near the floor) and providing the latter with
a collar boss, or projection which is acted against by a bracket or projection
attached to the spindle carriage so that when the latter reaches the end of its
stretch it automatically raises the Mendoza so as to throw the back shaft
driving wheels out of gear substantially as herein before described and illustrated
by the drawings annexed.
