Improvements in Self-acting Mules.
SAMUEL BOWDEN 21 Morris Street Oldham Lancashire England Mule Over-
looker do hereby declare the nature of this invention to be as follows:
A bracket into which is inserted a travelling screw which screw is actuated by a
wheel and pinion the pinion being driven by the faller coming in contact with a
ratchet wheel and catch wich depresses the catch one tooth of the ratchet wheel.
When the faller releases catch a spring which is attached draws the catch to its
old position and the ratchet wheel is worked one tooth. This gives motion to the
pinion and from pinion to wheel and the screw being keyed to wheel receives motion
at the same time. By this action the screw is forced back and the depressing takes
place later every draw the mule takes.
The original stud which in the old arrangment is bolted to the headstock side
and against which the faller finger pressed is taken out and the travelling screw
substituted in place of same but the faller finger is the same as in the old motion.
Dated this 4th day of July 1893.

Improvements in Self-acting Mules.
•
I, SAMUEL BOWDEN, of 21 Morris Street, Oldham, in the County of Lancaster,
Mule Overlooker, 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 motion at present commonly in use for depressing the counter faller of
mules at the termination of the inward run of the carriage consists of a fixed stud
or stop against which a depending arm or lever on the counter faller shaft comes in
contact as the carriage moves inwards.
This invention is designed to provide a depressing motion which will be auto-
matically altered or moved back at each draw of the carriage so as to depress the
counter faller a little later each run than the preceding one, and it consists in the
application to the headstock framing of a travelling stud or pin mounted in a
suitable bracket and caused to travel by a screw thereon actuated by a ratchet
wheel and pinion the ratchet of which is moved the required distance by the faller
shaft coming in contact with the arms which carry it.
It will be fully described with reference to the accompanying drawings in which
the position of the appliance on the headstock and in relation to the faller shaft is
illustrated.

which fits into an internal screw in the bush b of the bracket B, and on the extremity
of the screwed end d' is placed a pinion H or other gear wheel. The pinion H is
driven by a second pinion or wheel I on a loose stud J on the other end of which is
placed the ratchet wheel K by which it is rotated.
The ratchet wheel K is actuated by a pawl L on a pivoted arm or lever M which
is pivoted on the stud J. The arm or lever is provided with an inclined face m
with which the faller shaft G comes in contact each time the carriage runs back.
The lever M is moved in one direction by contact of the faller shaft G and is drawn
back in the opposite direction by the spring N. A set screw n regulating the
distance to be travelled.
When in operation the travelling stud D is set extending out from the bracket B
towards the carriage when the carriage runs in the arm or lever E on the counter
faller shaft F comes in contact with the end d and the faller is depressed thereby
to the desired extent. The faller shaft G comes in contact with the inclined face m
of the arm or lever M and moves back the pawl L over one or more teeth on the
ratchet wheel K, as the carriage moves away and the faller releases the lever M
the spring N draws the arm M and pawl L back again rotating the wheel K the
stud J and the pinion I. The pinion H with which the pinion I gears is thus
rotated and with it the travelling stud D which at each movement is drawn in by
the screw d¹ thereon so that at each succeeding inward run of the carriage it travels
further than the previous time before the faller is depressed.
By this arrangement I find that better or more even work is produced in the
building up of the cop a harder nose being formed and of better or more
gradual taper.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The combination with a mule of a faller depressing motion capable of being
automatically moved or altered by the carriage so as to allow of a longer travel of
the carriage at each succeeding inward run before depressing the counter faller
substantially as described.
2. In a mule the combination with the headstock framing A and bracket B of
the travelling stud D with a screw thread on one end, the ratchet wheel K, the
stud J, pinions H and I, and the pivoted arm M substantially as and for the
purpose described.
3. An automatic faller depressing motion for mules having the several parts
constructed and arranged in combination substantially as described.
