PROVISIONAL SPECIFICATION.
Improvements in or relating to Clutch Gear.
We, NORMAN KNOWLES and WILLIAM PHILIPSON trading under the style or
firm of The Mersey Rubber Company, Bank Quay, Warrington in the County of.
Lancaster, India-rubber Manufacturers, do hereby declare the nature of our
said invention to be as follows:-
:-
This invention refers to improvements in or relating to clutch gear for driving
india-rubber and other machinery and is designed to facilitate the disengaging of
the clutch in case of accident, also for means for locking the same when in gear.
The clutch is made in halves, one being mounted on a shaft and the other slides on
a key or feather on the driving shaft. Each half of the clutch is provided with
claws fitting between each other when put together; the driving surfaces of the
same being tapered so that as soon as the engaging gear is unlocked the sliding
portion will instantly slide out of gear automatically. For the purpose of locking
the clutch in gear the operating handle or its equivalent is provided with a rod or
link having a lip or catch engaging with a semi-circular or other like portion of a
shaft mounted in suitable fixings. When it is necessary to disengage the clutch it
is effected by simply turning the shaft so as to displace the lip or catch on the rod
or link. The shaft may be operated by a hand lever, quick threaded screw, or
other suitable mechanical means. Apparatus for actuating the operating lever or
its equivalent from the front of the machine or otherwise may be employed
consisting of wheels, chains, shafts, or other mechanical means to suit the position.
The operating handle or lever for engaging the clutch may also be locked by a
quick threaded screw, and actuated by wheels, chains, shafts, or other means from
the front of the machine or otherwise to allow of the same being thrown out of
gear in case of accident and the like.

DESCRIPTION OF DRAWINGS.
Fig. 1 is a longitudinal elevation of our improved clutch gear-Fig. 2 a plan,
and Fig. 3 an end view.
The clutch is made in halves consisting of the parts A and B; the part A being
attached to the wheel C and mounted on the shaft D. The part B is disposed on
the driving shaft E so as to slide on the key or feather G. Each half of the
clutch is provided with the claws H and I respectively, arranged to fit between
each other when put together as shown in Figs. 1 and 2. The driving surfaces J
and K are tapered so that as soon as the engaging gear is unlocked the sliding
portion B of the clutch will automatically slide out of gear on the shaft E and
the key or feather G by the action of the part A. The driving portion B of the
clutch is provided with the annular slot L in which fits the segments M fitted
with the pins N in the side levers (). The latter are mounted on the shaft or
centre P in the bearings Q secured to the floor or otherwise. On the shaft or
centre P is fixed the handle or lever R to which is attached the rod or link S by
the pin T. The rod or link S is provided with the lip or catch U which engages
with the semi-circular shaft V mounted in the fixings or bearings W. When it
is necessary to disengage the part B from the part A it is effected by turning the
semi-circular shaft V by the handle or lever X, by which action the lip or catch U
is released and the rod or link S and the handle R assume the position shown in
dotted lines in Fig. 1, this being effected by the part B of the clutch being forced
out of gear by the action of the tapered surfaces J and K.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In combination with clutch gear the use and employment of the tapered
driving surfaces J and K, substantially as described for the purpose specified.
2. In combination with clutch gear with tapered driving surfaces the use of
the lever R, rod or link S with a lip or catch working in conjunction with a semi-
circular shaft to hold the clutch in gear and to release the same when the said
shaft is rotated, substantially as described and shown in the annexed drawings.
