IMPROVEMENTS IN SELFACTING MULES
Year: 1884

page_text: I JAMES MACQUEEN of Bury in the County of Lancaster Machinist do hereby
declare the nature of said invention for IMPROVEMENTS IN SELFACTING MULES
to be as follows viz:-
A new arrangement of gearing, and method of operating the cam shaft.
In my arrangement of gearing I utilize the ordinary band driven by a pully on
the counter shaft which drives the headstock for the purpose of driving the
backing-off, cam shaft, and drawing up scroll shaft, From tho said pully on the
counter shaft I drive a pully fixed on a shaft carried in a bracket which radiates
from the centre of the rim shaft, on the other end of said shaft I fix a pinion
which I gear into the large wheel on one part of the backing-off cono, which part
of cone I mount to run loose on the rim shaft, the other part of the cone is loose
on the boss of a disc which I key fast on the rim shaft, the disc has two slots to
receive two projections on the cone part which works on it in the manner which is
well known On the back of tho large wheel of the backing-off cone I cast a bevil
wheel which I gear into a pinion on the top of an upright shaft, and on the bottom
of said shaft is a friction clutch and bevil which gears into the scroll shaft in the
usual manner-The cam shaft is geared into the large wheel on the backing-off
cone in the usual manner.
The bracket which carries the shaft with band pulley and spur pinion can be
moved higher or lower round the centre of the rim shaft and theroby slacken or
tighten the baud without the intervention of a tightening pulley, and this bracket
can also be lengthened or shortened between the centres so that by changing the
pinion the speed of the backing-off, cam shaft, and up-taking, can be altered at
pleasure.
In operating the cam shaft I use any well known form of shaft either driven by
a clutch or friction cones, on this shaft I fix a can with two inclines and stops on
its periphery but not in the same plane-In front of this cam I fix an open bracket
which carries the square end of a change rod which runs from front to back of the
headstock, this square end has an adjustable projection the end of which bears
against the incline on the cam and its top side receives the stop of said cam-I fix
a stud on any convenient place on which I place a bell crank lever which is free to
move on said stud, one end of this lever takes into a groove of one part of the
clutch or cone. The other end bears against the afore-said square end of sliding

page_text: rod, a spring is attached in any convenient manner to this ond of the bell crank
lever which causes the clutch to gear when the projection on the rod end is moved
out of the way of the stop and incline on the cam, and into the path of the other
incline and stop on said cam, when this second incline comes into contact with the
projection on the rod end the rod end is driven from the centre of the shaft and
being in contact with the bell crank lover pushes it also back and the lever
withdraws the clutch and stops the cam shaft.
The rod is moved on end by the carriage or otherwise for relieving the stop and
allowing the clutch to be drawn into gear by the spring and thus giving part of a
revolution to the cam shaft,. The said rod has therefore two movements one to or
from the centre of the cam shaft which disengages the clutch and one on end by
the action of the carriage or otherwise which relieves the camshaft and engages
the clutch.

page_text: I, JAMES MACQUEEN of Bury in the County of Lancaster Machinist do hereby
declare the nature of said invention for IMPROVEMENTS IN SELPACTING MULES
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:―
My Invention consists in a new arrangement of gearing, and method of operating
the cam shaft.
In the accompanying sheet of drawings Figs. 1 and 2 represent an elevation and
end view of part of the rim shaft of a selfacting mule, and illustrates my new
arrangement of gearing. Figs. 3 and 4 are diagrams shewing my mode of operating
the cam shaft. The same letters refer to similar parts us shewn in the different
Figures.
In my arrangement of gearing I utilize the ordinary band driven by a pulloy on
the counter or top driving shaft which drives the headstock for the purpose of
driving the backing-off the cam shaft and the drawing up scroll shaft From the
said pulley a. (Figs. 1 and 2) on the top driving shaft b. I drive the pulley c. fixed
on the shaft d. carried by the bracket c. which radiates from the centre of the rim
shaft on the other end of the shaft d. I fix the pinion which I gear into the
large wheel on one part of the backing-off friction cone which part of cone runs
loose on the rim shaft f―The other part of the friction cone i (Fig. 1.) is loose on
the boss of a disc which I key fast on the rim shaft-the disc has two slots to
receive two projections on the cone part 2. which works on it in the manner which
is well known.

On the back of the large wheel h, of the backing off cone I cast the bevil
wheel j, which gears into the pinion k, on the top of the upright shaft l, on the
bottom of which is the friction clutch or cone m, and bevil n." which gears into the
bevil o. and drives the drawing up scroll shaft p, in the usual manner-The cau
shaft q is geared by the wheel into the large wheel h. in the usual manner.
The bracket c. can be moved higher or lower round the centre of the rim shaft f.
and thereby slacken or tighten the driving band without the intervention of a
tightening pulley and is held in position by bolts in the slots s¹ on the buffet 8. of
the head stock framing-The bracket is also inade in two pieces as shewn at e', so
that it can be lengthened or shortened between the centres to allow for changing
the pinion g, and thereby allowing the speed of the backing off, the cam shaft and
drawing up, to be altered at pleasure. In operating the cam shaft 1 use any well
known form of shaft either driven by a clutch box or friction cone-On the cam
shafty (Figs. 3 and 4) I fix the cam t. which has two inclines u and u', and two
stops and u³ on its periphery but not in the same plane. In front of this cam I
fix to the headstock framing the open bracket v. which carries freely the square
end w. of the change rod x. which rod runs from front to back of the heal stock.
The square end w. has an adjustable projection y. which bears against the incline u.
of the cam t. and its top side receives the stop u³ of the cain.
I fix a stud on any
convenient part of the framing on which I place the bell crank lever a¹ (Fig. 3.)
which is free to move on said stud, one end of this lever takes in the groove b' of

page_text: one part of the clutch or friction cone on the cam shaft, the other end of the lever
at a³, bears against the square piece w. of the sliding rod -I attach one end of
the spring c. in any convenient manner to the framing and the other end to the
long arm of the bell crank lever as shown in the drawing-In moving the rod x.
end ways, by action of the carriago or otherwise until the projection y. is free of the
stop us and into the path of the incline u' and stop u³-the friction cone is then
pulled into gear by the spring c¹ and the cain is allowed to make one half of a
revolution and the incline u. acting on the projection y. pushes the square piece w.
back in its support v. and carries the long end of the bell crank lever with it, thus
separating the friction cones and stopping the cam shaft-The stop u³. of the cam
is now resting on the projection y-In moving the sliding rod x. the reverse way
until the projection y. free of the stop us. and into the path of the incline u. and
stop us, the same movements as described above take place and so on every draw
of the mule.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
First-The pulley c, the lever c, the pinion g driving the backing-off wheel and
wheel on cam shaft, the beviljon back of backing off wheel for driving bevil on
the upright shaft which drives the drawing up scroll shaft-either separately or in
combination as described and set forth in the drawings.
Second-The cam t on the cam shaft with its inclines and stops in combination
with the square piece wand projection y on the end of the sliding rod x and tho
bell crank lever a' for the purpose of throwing in and out of gear the clutch or
friction cone of the cam shaft as described and set forth in the drawings.
