PROVISIONAL SPECIFICATION.
Improvements in Self Acting Mules and Twiners.
I, JOHN CLEGG, of the firm of Asa Lees and Company Limited, of Soho Iron
Works, Oldham, in the County of Lancaster, Manager of Mule Department, do
hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in the strap shifting motion of self acting
mules and twiners and the chief object of my improvements is to enable the bowl
mounted on the mule carriage, and which actuates the depressing lever, to be
adjusted and set without the use of a screw key.
In carrying my improvements into effect I combine a stop motion operated by
hand or foot but preferably by hand with the inclined lever and rod of the ordinary
automatic strap relieving motion substantially in the manner specified in the
invention for which Letters Patent numbered 8172 and dated May 13th 1891 were
granted to me. I mount on the mule carriage a slotted bracket or frame which
receives the squared end of the stud which carries the bowl or small roller which
actuates the depressing lever. The squared portion of the stud is tapped and forms
a nut through which passes a screw supported at each end in the bracket or frame
and provided with a handle by turning which the position of the bowl can be
adjusted to any point desired.
When the bowl acts upon the depressing lever the strap relieving rod jointed to
said lever is moved and transmits its movement to the strap fork lever and so shifts
the driving belt (or belts) from the fast to the loose pulley.
Although I have described and prefer to use the combined hand or treadle stop
motion and automatic strap relieving motion, yet I wish it to be understood that
my improved mode of mounting and adjusting the depressing bowl may be applied
to an ordinary inclined or other form of depressing lever.
Dated this 19th day of April 1892.

COMPLETE SPECIFICATION.
Improvements in Self Acting Mules and Twiners.
1, JOHN CLEGG, of the firm of Asa Lees and Company Limited, of Soho Iron
Works, Oldham, in the County of Lancaster, Manager of Mule Department, 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:-
My invention relates to improvements in the strap shifting motion of self acting
mules and twiners and the chief object of my improvements is to enable the bowl
mounted on the mule carriage, and which actuates the depressing lever, to be
adjusted and set without the use of a screw key.
In carrying my improvements into effect I combine a stop motion operated by
hand or foot but preferably by hand with the inclined lever and rod of the ordinary
automatic strap relieving motion substantially in the manner specified in the
invention for which Letters Patent numbered 8172 and dated May 13th 1891 were
granted to me. I mount on the mule carriage a slotted bracket or frame which
receives the squared end of the stud which carries the bowl or small roller which
actuates the depressing lever. The squared portion of the stud is tapped and forms
a nut through which passes a screw supported at each end in the bracket or frame

page_text: and provided with a handle by turning which the position of the bowl can be
adjusted to any point desired.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Figure 1 is a side elevation and Fig. 2 a plan illustrating my improvements as
applied to the strap shifting motion of a self acting mule.
In these views, a designates the frame side, & the rim shaft, c c¹ the fast and
loose pulleys thereon, d d the pair of driving belts, e the strap fork lever and f the
strap relieving rod which is connected to the strap fork lever e by the link f',
arm and shaft f³; g is the depressing lever which is fulcrumed at on a bracket i
secured to the frame side and is jointed at j to the strap relieving rod f; k is the
latch which is pivoted at A¹ to the bracket i and is so weighted and its movement
so limited by stop pieces that it always tends to remain in one of the two positions
indicated respectively by dotted and full lines in the drawings.
When in the position shown in full lines the latch k is ready to engage a
projection glon the depressing lever g; but when in the other position indicated the
fever
can be depressed without its being locked by the latch k.
The above parts constitute the combined hand stop motion and automatic strap
relieving motion before mentioned.
On the mule carriage m I fix the bracket or frame n in which is fitted the
squared end of the stud o which carries the depressing bowl p; is the screw
which is supported in each end of the bracket n and passes through the tapped
squared portion of the stud o; on the screw q is fixed a handle y' by turning which
the position of the stud o and depressing bowl p can be adjusted as required.
When the bowl p acts upon the depressing lever g the strap relieving rod f
jointed to said lever is moved and through its connections tranmits this movement
to the strap fork lever e and so shifts the pair of driving belts d d (or a single belt
as the case may be) from the fast pulley c to the loose pulley c¹.
When depressed by the bowl p, or by hand as the case may be, with the latch k
in the position shown in full lines the lever g is caught by the latch and the belts
are retained in their position on the loose pulley until the depressing lever is again
unlatched.
Although I have described and prefer to use the combined hand or treadle stop
motion, and automatic strap relieving motion, yet I wish it to be understood that
my improved mode of mounting and adjusting the depressing bowl p may be applied
to an ordinary inclined or other form of depressing lever.
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 :-
1. Mounting the stud of the depressing bowl upon a screw substantially in the
manner herein set forth in order that said bowl may be adjusted and set when
required without the use of a screw key.
2. The combination with a combined hand or treadle stop motion and automatic
strap relieving motion, of a depressing bowl mounted upon a stud which is fitted in
a bracket and arranged to be adjusted by a screw substantially as and for the
purposes herein set forth.
