IMPROVE- MENTS IN SELF ACTING MULES FOR SPINNING
Year: 1884

page_text: I ENOCH DUNKERLEY of Navigation Inn, Hollinwood Oldham in the County
of Lancaster Spinner do hereby declare the nature of my invention for "IMPROVE-
MENTS IN SELF ACTING MULES FOR SPINNING," to be as follows:-
My invention relates to that part of a self acting mule which is termed the
winding on click and which gears into a ratchet wheel fixed on the drum shaft
near to the headstock of a self-acting mule and has for its object to provide mean
for bringing the click more suddenly in and better out of gear with the ratchet
wheel at the time of commencement and stoppage of the winding up operation
than has heretofore been the case.
Previous to my invention the arm of the click was provided with two pro-
jections which engaged the longer end of a clip spring, sprung onto the boss of a
ratchet wheel causing the click to be brought in and out of gear with the ratchet
wheel at the required times. My invention consists in forming the end of the said
click arm with two cams a certain distance apart, one being of a semicircular and
the other of a somewhat oval shape in section. The long end of the clip spring
when engaged between the said two cams will produce and increased leverage and
cause the click to drop into and lift out of gear with the ratchet wheel at the
required time more suddenly and with more clearance, which will prevent a great
deal of wear and tear of the click ratchet wheel and clip spring.

page_text: 1, ENOCH DUNKERLEY, of Navigation Inn Hollinwood, Oldham in the County of
Lancaster Spinner, do hereby declare the nature of my invention for "IMPROVE-
MENTS IN SELF-ACTING MULES FOR SPINNING," 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 that part of a self-acting mule which is termed the
winding on click and which gears into a ratchet termed click wheel fixed on the
drum shaft near to the headstock of a self-acting mule and has for its object to
provide means for bringing the click more suddenly in and better out of gear with
the ratchet or click wheel at the time of commencement and stoppage of the
winding up operation than heretofore has been the case.
And in order that my invention may be better understood I have caused to be
appended hereunto one sheet of drawings marked witli letters of reference corro-
sponding letters indicating-like-parts in the various figures. Fig 1 on the annexed
drawing is a side view of an old click wheel showing the click out of gear. Figs 2
and 3 are also side views showing the click in and out of gear with the ratchet or
click wheel respectively but in accordance with my invention.
Previous to my invention the arm of the click a sec Fig 1, was provided with
two projections a¹ which engaged the longer end of a clip spring c. sprung onto
the boss of a ratchet or click wheel d causing the said click to be brought in and
out of gear with the ratchet or click wheel c at required times.
In carrying out my invention and referring to Figs 2 and 3 I form the lower
end of the said click arm with two cams e and f'a certain distance apart one being
of a semi-circular and the other of a somewhat oval or similar shape in section, the
working surfaces being parallel to each other. The longer end of the clip
spring c I form straight instead of bent in order that it may be engaged between
the said two cams more easily and when brought into action will produce an
increased leverage and cause the click a to drop into and lift out of gear with the
ratchet wheel d at the required time more suddenly, with more clearance, and
without increasing the travel of the spring end b which will prevent a great deal
of wear and tear of the click or ratchet wheel and clip spring.
The click described may also be applied to any other ratchet wheel of a self-
acting mule where a similar movement is required.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I wish it to be under-
stood that what I claim is
The click a provided with two cam shaped projections c and ƒ the working
surfaces of which being parallel to each other for the purpose specified substantially
as described and illustrated by Figs 2 and 3 in the annexed drawing.
Dated this 16th day of January AD. 1885.
