Improvements in Machines or Appliances for Shearing or Olipping
Wool, Hair, or other like Material or Substance.
We, WILLIAM Bown, of 308, Summer Lane, Birmingham, in the County of
Warwick, Manufacturer, and GEORGE CAPEWELL, of 114, Upper Thomas Street,
Aston, near Birmingham, aforesaid, Machinist, do hereby declare the nature of this
invention to be as follows:-
These improvements relate to that class of shearing or clipping machine or
appliance which is driven by motive or other power and having motion imparted
thereto by means of a flexible shaft, chain, band or belt or other suitable means,
which motion is transmitted from the motive or other power to the clipping machine
or appliance and has for its object the means whereby the reciprocatory or other
action by which the cutting plate or plates are worked to and fro across each other
may be started or stopped instantaneously at the will of the operator, whilst the
flexible shaft or its equivalent which transmits the motion still continues to revolve,
or work thereby dispensing with the unnecessary working of the cutting plate or
plates when not in actual use; by these means the cutting plate or plates retain their
sharp cutting edges much longer than usual and the necessity of stopping the
flexible driving shaft or other motive power for oiling the teeth of the cutters,
cleaning or other purposes is dispensed with.
In carrying our improvements into effect we take for example a shearing or
clipping machine or appliance by preference one with a spindle or shaft passing
through the body, handle or frame of the machine and working or revolving
therein. This spindle is used in combination with other parts for the purpose of
imparting motion to the cutting plate or plates. To one end of this spindle is
attached suitable gearing or universal joint for imparting motion to the said spindle
through the medium of a flexible shaft or other suitable means. Our improvements
consist in placing or attaching to any convenient part of the shearing machine or
any attachment connected to or in combination with the machine but preferably on
the top of the body or handle a small lever or levers, or stop piece or pieces, or
their equivalents in combination with a spring or springs for the purpose
of 'connecting and disconnecting the spindle with the gearing or universal joint
or other connections. In combination with this lever or stop piece is a suitable
clutch; bolt, catch or cone shaped part or parts or their equivalents whether
frictional or otherwise, which said clutch or its equivalent is formed so as to slide
upon the spindle or other parts formed on the spindle for that purpose but is
prevented from revolving thereon. Instead of having the gear wheel on the spindle,
or universal joint, fixed, as usual we fasten it to a short shaft or collar or it's
equivalent which revolves independently of the spindle passing through the body.
The other end of this short shaft or collar is so formed as to take into or against the
sliding clutch or its equivalent, or an independent' piece may be attached thereto
for that purpose.
We may place the sliding clutch or its equivalent on the short shaft or collar or its
equivalent when desired instead of on the spindle and form a corresponding
stationary clutch or its equivalent on the spindle; being vice versa to the former
method. It will thus be seen that when the operator presses or actuates the lever
or stop piece or its equivalent the spindle is connected with the gearing or universal
joint and the cutting plate or plates put in operation, or vice versa.

Improvements in Machines or Appliances for Shearing or Clipping
Wool, Hair, or other like Material or Substance.
We, WILLIAM BOWN, of 308, Summer Lane, Birmingham, in the County of
Warwick, Manufacturer, and GEORGE CAPEWELL, of 114, Upper Thomas Street,
Aston, near Birmingham, aforesaid, Machinist, 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 :-
These improvements relate to that class of shearing or clipping machine or
appliance which is driven by motive or other power and having motion imparted
thereto by means of a flexible shaft, chain, band or belt or other suitable means,
which motion is transmitted from the motive or other power to the clipping machine
or appliance and has for its object the means whereby the reciprocatory or other
action by which the cutting plate or plates are worked to and fro across the comb
or combs may be started or stopped instantaneously at the will of the operator,
whilst the flexible shaft or its equivalent which transmits the motion still continues
to revolve.
In order that our invention may be more clearly understood we have annexed
the accompanying sheet of drawings.
Fig. 1 is a plan view of a sheep shearing machine shewing part of the body or
tubular handle broken away.
Fig. 2 is a part side view of Fig. 1, and
Fig. 3 is a similar view shewing a different method of carrying our improvements
into practice.
A is the body or casing of the machine with which is formed a tubılar handle A¹
in which and in the body or casing are the bearings for supporting the main
spindle B which actuates the cutter C in its to and fro motion across the comb D.
Rotary motion is imparted to the said main spindle B by the universal gear
coupling E which receives its motion by means of a flexible shaft, chain, band or
belt or other suitable means driven from the main driving power.
In order to start or stop the machine at the will of the operator we place on any
convenient part of the main spindle B or other suitable part of the machine, but by
preference on that portion of the said main spindle B which comes underneath the
tubular handle A¹, a sliding clutch F or its equivalent which takes into a
corresponding clutch G or its equivalent revolving loosely on the main spindle B,
or the said clutch G or its equivalent may be fastened to or form part of an
independent spindle. Or instead of employing two clutches we may employ two
friction cones or a fast and loose pulley. At the other end of the said revolving
clutch G is attached one of the universal gear coupling wheels a as shewn in dotted
lines Fig. 1.
It will be seen on reference to the drawings Figs. 1 and 2 that if the operator
presses down the lever H which is hinged at bit will cause the fork or clip c to
move the sliding clutch F into gear with the corresponding clutch G as shewn in
dotted lines Fig. 2; and when the operator releases the lever H the spring J will
force it up again thus removing the clutch F out of gear with the clutch G, or the
operation may be vice versa.
In Fig. 3 we have shewn a different method for connecting and disconnecting
the two clutches F and G. Instead of forming a fork or clip c on the end of the
lever H for clipping the clutch F, we extend the said lever H slightly beyond its
axis or hinge b as shewn at d, which clips or holds a pege working loosely in a hole
or bush fixed or formed in the tubular handle A'. On the periphery of the clutch F
we form a kind of eccentric f extending half way round the circumference by means
of which the peg e forces the said clutch F out of contact with the clutch G as
shewn in the drawings. The stop piece which comes in contact with the pege
preventing the said clutch F from revolving until released. To release the clutch F

page_text: so as to gear with the clutch G the operator presses down the lever H thereby
raising the peg e out of contact with the eccentric f and stop piece g, the coil
spring h or its equivalent forcing the said clutch F into gear with the clutch G, or
the operation may be vice versa.
It will be obvious that instead of employing the lever H for connecting and
disconnecting the clutches F and G we may when desired by slightly altering the
mechanism operate the same by pressing a stud or button or its equivalent or by
any other suitable arrangement.
Our improvements are equally applicable to horse clipping machines or other
similar shearing or clipping machines which are driven by motive power.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we would have it understood
that we do not confine ourselves to the precise details as herein shewn and described
as they may be varied or modified without departing from the principle of our
invention but what we consider new and wish to claim is :-
Firstly In a sheep shearing or clipping machine the means or method or their
equivalent for starting or stopping the said machine. at the will of the operator
substantially as herein shewn and described.
Secondly-In a horse clipping or shearing machine or other similar shearing or
clipping machine the means or method or their equivalent whereby the operator
can instantaneously start or stop the said machine substantially as herein shewn and
described.
Thirdly-Starting and stopping sheep shearing machines or horse clipping or
other similar shearing or clipping machines at the will of the operator while the
flexible shaft, chain, band or belt or other motive power for driving the same
continues to revolve.
