PROVISIONAL SPECIFICATION.
Improvements in Ratchet Gearing.
I, JOHN ELLISON of 5 Tyson Street, Pike's Lane, Bolton in the County of
Lancaster, Cotton Spinner, do hereby declare the nature of my said invention to be
as follows:-—
This invention relates to a sliding lever catch and is designed to operate toothed
gear in a safe and certain manner to reduce slip to a minimum. The sliding lever
catch is constructed with two or more slots to allow of the same being mounted on
pins or centres secured to any convenient part of the machine in close proximity to
the gear it is intended to operate. Each slot can be provided with means for
adjusting or regulating its stroke or traverse in moving from one tooth to another.
This sliding lever catch can be provided with means for attaching a spring to
operate it in either direction according to the various requirements to which it may
be adopted. The pins or centres, on which the sliding catch is mounted, can be
secured to adjustable fixings or in slots to allow of the movements of the same being
regulated to a nicety. This invention can be applied with advantage to lathes,
drilling, and other machines, also to spinning and other machinery. In adapting it
as a winding catch for a spinning mule the supporting pins or centres, with or
without adjustments, are mounted on the winding crank or crank plate, and so
operates that when the mule carriage makes an inward run the crank or crank
plate rotates with the pins or centres, during which the sliding lever catch is
held back by a spring. The slots in this case are arranged so as to allow one
end of the catch to lift while the other end drops into the space between the
teeth in the wheel it is to operate. When the mule carriage has completed its
inward run the winding wheel will leave the catch, and when the winding crank
plate reverses its action the said catch will be thrown out of gear instantly.

Improvements in Ratchet Gearing.
1, JOHN ELLISON of 5 Tyson Street, Pike's Lane, Bolton in the County of
Lancaster, Cotton Spinner, do hereby declare the nature of my said invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-

instantly.

Fig. 4 is a part front view showing my improved sliding lever catch out of gear.
Fig. 5 is a front view of spur and ratchet gear fitted with my improved sliding
lever catch, and
Fig. 6 is a sectional elevation through line A. B. in Fig. 5.
C is the sliding lever catch; D the winding crank or crank plate of a spinning
mule E the winding spring; G the ratchet wheel, and F the cylinder shaft.
To the winding crank or crank plate D is fixed the centre H by the nut I. On
the centre H is mounted the adjustable fixing J provided with the screw .K which
passes through the centre H, and by which the fixing J can be moved in either
direction to allow of the sliding lever catch C being set to a nicety according to the
pitch of the ratchet wheel. The sliding lever catch C is constructed with the
slots L, and fits or sits on the pins M attached to the adjustable fixing J. The
sliding lever catch is secured on the pins M by the split or other pins T. If
desired one or both slots L can be provided with the screwed pin N and lock nut O
for regulating or adjusting the stroke or traverse of the sliding lever catch C in
moving from one tooth to another on the ratchet wheel G. The sliding lever
catch C may be provided with the pins R to receive the end of the winding
spring E, by which the catch C will be thrown out of gear, as shown in Fig. 4,
when the winding crank or crank plate D reverses its action. In adapting this
invention as a winding catch for a spinning mule numerous advantages accrue as it
is certain in its action, by which there will be no liability to snarled or snicked
cops as are caused by the old style of catch slipping over the ratchet wheel teeth,
which action produces slack winding and under wound cop bottoms, flussy-noses,
broken winding wheels, broken catches, and winding chains.
This invention can be applied with advantage to lathes, drilling, and other
machines, spinning and other machinery wherein ratchet gearing is employed. As
it is impossible to show all the arrangements to which this improved sliding catch
may be applied I would have it understood that the same can be mounted on levers
and other parts of machinery to which it may be applicable. For instance, on
looking at Figs. 5 and 6 it will be seen that one or more of the catches C can be
employed to operate on the ratchet wheel G to ensure of its being rotated as
long as the prime mover, to which the supporting pins M are attached for carrying
the said catch or catches C, is in motion in the direction indicated by the arrow.
In Figs. 5 and the supporting pins M are attached to the spur wheel S, by which
the catches C are placed in contact with the ratchet wheel G when rotating in
the direction indicated by the arrow. Immediately each catch C passes the hori-
zontal centre line, to the plane of the paper, it will drop out of action and remain
in that position until the vertical centre line, to the plane of the paper, is passed
when it again engages with the ratchet wheel G and so on. If by any means the
ratchet wheel G should assume a greater speed than the wheel S all the catches C
will be thrown out cf gear, by which breakages will be prevented. Although the
pins M are shown secured to the web of the wheel S they can be mounted in slots
or in adjustable fixings secured thereto as in Figs. 1, 2, and 3. In the latter case
the said fixings J will be secured to the web of the wheel S.

page_text: 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
1. In combination with ratchet gearing the use of a sliding lever catch, with or
without means of adjustment, for the purpose specified.
2. In combination with a sliding lever catch the use of the adjusting screw N for
the purpose of regulating its stroke or traverse on the pins or supports M, sub-
stantially as described.
3. In ratchet gearing the use of the fixing J with the means of adjustment and
the pins M in combination with the sliding lever catch C provided with the slots L,
substantially as described.
