PROVISIONAL SPECIFICATION,
An Improved Machine for Clipping or Shearing Hair and other
Materials.
We THOMAS WARSOP of Coniston viá Ambleside, Engineer, and GEORGE WIGLEY
of Marlborough House, Elm Avenue, Nottingham, Silk Merchant, do hereby declare
the nature of this invention to be as follows:-
-
This Invention has for its object, the application of the motive power of either
Compressed Air, Steam, Gas, or Water, to the Knife or Knives of Clipping and
Shearing Machines; which are now usually worked by two Hands.
For this purpose, we make the Machine preferably with one hollow Stem or Handle;
carrying at its upper end a fixed serrated Knife; and, in this Handle we enclose a
small Cylinder, fitted with a Piston; which is rapidly reciprocated therein by
compressed Air, Steam, Gas, or Water; supplied and controlled by the usual means.
This Piston is connected in a suitable manner-at its upper end-with a second Knife,
serrated on its upper side, and sliding in suitable Guides across the face of the fixed
Knife.
The rapid reciprocating action of the Piston is transmitted to the movable
Knife; in such a manner, that the serrations in the movable Knife pass rapidly to
and fro alongside and across the serrations in the fixed Knife; and by this means
clip off or shear all Hairs or other materials that enter these serrations.
The Compressed Air or other motive fluid, is conveyed to the Cylinder in the
Handle, by a Flexible Hose attached to the Handle of the Machine.
In some cases, we use two or more Cylinders and Pistons to work one or more
movable Knives."

COMPLETE SPECIFICATION.
An Improved Machine for Clipping or Shearing Hair and other
Materials.
We, THOMAS WARSOP of Coniston vid Ambleside, Engineer, and GEORGE WIGLEY,
of Marlborough House Elm Avenue, Nottingham, Silk Merchant, 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:
This Invention has for its object the application of the motive power of either
Compressed Air, Steam, Gas or Water to the Knife or Knives of Clipping and
Shearing Machines; which are now usually worked by two Hands.
For this purpose we make the Machine preferably with one hollow Stem or
Handle; carrying at its upper end a fixed serrated Knife; and in this Handle we
enclose a small Cylinder, fitted with a Piston; which is rapidly reciprocated therein
by compressed Air, Steam, Gas or Water; supplied and controlled by the usual
means. This Piston is connected in a suitable manner at its upper end, with a
second Knife, serrated on its upper side, and sliding in suitable Guides across the face
of the fixed Knife.
The rapid reciprocating action of the Piston is transmitted to the movable Knife, in
such a manner, that the serrations in the movable Knife pass rapidly to and fro
alongside and across the serrations in the fixed Knife; and by this means clip off or
shear all Hairs or other materials that enter these serrations.

page_text: The Compressed Air or other motive fluid is conveyed to the Cylinder in the
Handle by a Flexible Hose attached to the Handle of the Machine.
In some cases, we use two or more Cylinders and Pistons to work one or more
movable Knives.
In order that our Invention may be fully understood, and readily carried out 5
and into effect, we will proceed to describe the accompanying sheet of Drawings,
reference being had to the letters marked thereon.
Figure 1 is a Sectional Elevation of our arrangement of our Improved Machine for
Clipping Hair and other Materials.
Fig. 2 is an outside Elevation of another arrangement of our Improved Clipping
Machine.
Fig. 3 is a Sectional Elevation of a third arrangement or mode of working our
Improved Clipping and Shearing Machine.
Similar letters refer to similar parts throughout the several views.
In these views A is the hollow Stem or Handle of the Machine, carrying at its upper 1
end the fixed serrated Knife M.
In the Handle A, we form a small Cylinder B, fitted with a Piston, C; and
Piston Rod D, fitted at its upper end with the Crosshead E-which in Fig. 1-is.
connected by the Bell-Crank Lever F, working on Stud G fixed to the Knive M.
The other end F¹ of this Bell-Crank Lever, engages with the Stud Pin H, fastened
to a second serrated Knife N, which slides on the Guide Pins K and K¹ on the
Knifė M. The action of the whole arrangement is such that when the Piston C
is made to reciprocate in Cylinder B, this motion is transmitted by the Piston
Rod D, Crosshead E and Bell Crank Lever F to the Knife N-serrated on ´its
upper side and its serrations N₁ pass rapidly to and fro alongside and across
the serrations M₁ in the fixed Knife M; by which means all Hairs and other like
materials that enter these serrations are sheared or clipped off.
In some cases as shown in Fig. 2-we fix an inclined Die L to the Crosshead E,
and this Die L working in a similarly inclined Slot O in movable Knife N, transmits
the reciprocating action of the Piston Rod D directly to the movable Knife N.
In some other cases-as shown in Fig. 3-we couple a small Connecting Rod I
to Crosshead E. This Rod I at its upper end receives a Crank Pin J, in Disc O,
which revolves on Axle. P. fixed to Knife M. The Crank Pin J also works in the
Slot F of Bell Crank Lever F.; and the action of this arrangement is such that
the reciprocating action of Piston C, is transmitted by Piston Rod D, and Rod I,
to Crank Pin J and Disc O, which revolves rapidly; and, by means of the Bell-
Crank Lever F, causes the Knife N to reciprocate rapidly alongside, and across
Knife M; as and for the purposes before described.
The Piston C is caused to reciprocate rapidly in the Cylinder B by Compressed
Air, Steam, Gas or Water conveyed thereto by a Flexible Hose Pipe R', attached to
the Branch R of Handle A by a suitable coupling.
In Fig. 1, the Cylinder B has an ordinary inlet port 1, through which the
Compressed Air or Motive fluid enters space 6, and exerts a constant downward
pressure on the upper side of Piston C; it has also a long induction passage 2 with
two portways 3 and 4, and an outlet or exhaust port 5-shown by dotted lines.
The Body of the Piston C is of such a length, as to cover induction port 3 and
exhaust port 5.
The action is as follows:-the constant pressure of the motive fluid in space 6 forces
Piston C down until port 3 is uncovered and allows the motive fluid to pass down
passage 3-2-4 into space 7; where, acting on the larger area of Piston it arrests
its downwards stroke, forces the Piston upwards again, until port 3 is closed, and the
supply of the motive fluid cut off from underneath Piston C; the inertia of which,
carries it further upwards until Exhaust Port 5 is uncovered by it, and the pressure
under Piston C released. The constant pressure in 6 forces Piston 6 down again as
before.
In a second modification-shown in Fig. 3-we cause the Motive fluid to act on
the underside of Piston C to force it upwards, until in its passage it uncovers the

page_text: Exhaust Ports 5, when the pressure under the Piston is momentarily released; and
the Spring T, compressed during the upward stroke of the Piston, drives it down again
to effect the downward stroke.
Or, the action of the Motive Fluid may be controlled in the Cylinder B-to cause
the reciprocating action of Piston C therein-by any other ordinary means; and we
would cbserve, that we lay no claim to any such means-as described or not-of
controlling the Motive Fluid.
Sometimes we use two or more Cylinders and Pistons to work two or more
movable Knives; and at other times-instead of the Cylinder or Cylinders being
stationary in the Machine Handle, we make it or them to oscillate therein.
Having now particularly described and ascertained the nature of our said Invention,
and in what manner the same is to be performed, we declare that what we
claim is :-
1st. The use and application of Compressed Air, Steam, Gas, Water or other
motive fluid to actuate one or more movable Knives of Machines for Clipping and
Shearing Hair, Wool or other analogous materials; by rapidly reciprocating a
Piston or Pistons working in a Cylinder or Cylinders attached to the said Machine,
substantially as hereinbefore described.
2nd. In Clipping and Shearing Machines, such as are referred to in the preceding
claim, the combinations and arrangements of Levers, Rods, and the other parts
shown in Figures 1-2 and 3 of the accompanying Drawings, for imparting a
reciprocating motion to Knife N from Piston C, substantially as shown and described.
herein.
3rd. Clipping and Shearing Machines in which compressed Air, Gas or other
motive fluid or Gas is used to drive one or more movable Knives for clipping or
shearing Hair, Wool, or other like substances; substantially as herein described,
and shown in the Drawings herewith.
