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 in the County of Warwick, Machinist, do hereby declare the nature of this
invention to be as follows :-
The object of our invention is to diminish the friction in the to and fro motion of
the cutting plates and other frictional parts of shearing or clipping machines or
appliances whether for hair, wool or other like material or substance and is a further
improvement on a prior Patent granted to us on the 26th day of January 1885
No. 1107.
My improvements consist in the use of one or more oscillating flat headed pins or
studs, or cone, triangular or T shaped pieces, or their equivalents, in combination
with one or more convex, globular, segmental or circular shaped bearing surfaces (or
their equivalents) formed on or attached to the clamping part or parts, bar or bars, or
other bearing parts (whether moveable or stationary) or to the cutting plate or plates
when desired.
In carrying our invention into practice we take for example an ordinary shearing
or clipping machine with a triangular or other shaped pressure bar to which we
attach or connect one or more of the oscillating flat headed pins or studs, or cone,
triangular or T shaped pieces, or their equivalents; by preference we use two of the
above mentioned oscillators in an upright position, the points or axes of which bear
against projecting parts or pieces, or take into holes, slots or recesses on the cutting
plate or other bearing piece, whilst the top or flat part of the oscillators bears against
the convex, globular, segmental or circular bearing surfaces formed on or connected
to the triangular or other shaped pressure bar (or vice versa). When the cutting
plate is moved to and fro the parts of the oscillators bearing against the plate or other
bearing part, oscillate upon their points or axes, and the top or flat surfaces move
without the slightest friction upon the convex, globular, segmental or circular bearing
surfaces formed on or connected to the triangular or other shaped pressure bar (or
vice versa).
The top and bottom bearing surfaces may both be formed of a globular, convex,
segmental or circular shape (or their equivalent) and used in combination instead of
separate, having a suitable oscillating piece inserted between them.
We may when desired cover the headed or other shaped oscillators in such a
manner as to effectually prevent any dirt or dust entering between the bearing
surfaces.
We do not confine ourselves to any particular shaped oscillator as any convenient
form suitable for making a rocking or oscillating movement may be employed.
Dated this 17th day of February 1890.

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 CAPRWELL, of 114 Upper Thomas Street,
Aston, near Birminghain 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 :-
The object of our invention is to diminish the friction in the to and fro motion of
the cutting plate and other frictional parts of shearing or clipping machines or
appliances whether for wool, hair or other like material or substance and is a further
improvement on a prior Patent granted to us dated the 26th day of January 1885,
No. 1107. Our improvements consist in the use of one or more oscillating flat
headed pins or studs, or cone, triangular or T shaped pieces or their equivalents, in
combination with one or more convex, globular, segmental or circular shaped bearing
surfaces (or their equivalents) formed on or attached to the clamping part or parts,
bar or bars or other bearing parts (whether moveable or stationary) or to the cutting
plate or plates when desired.
In order that our invention may be better understood we have annexed the
accompanying sheet of drawings. In Fig. 1 which is part sectional side elevation
and Fig. 2 which is longitudinal section we have shewn our improvements as applied
to a horse clipping machine. A is the top cutting plate which is held in position by
the triangular or other shaped pressure bar B to which we attach or connect one or
more oscillating flat headed pins or T shaped pieces C, or cone or triangular shaped
pieces or their equivalents, but by preference we use two of the T shaped oscillators (
in an upright position as shewn at. Fig. 2, the points or axes a which are round bear
against the parts or projecting pieces or take into holes, slots or recesses formed on
or inserted in the cutting plate A or other bearing piece, while the top or flat part d
of the oscillators C bears against the convex globular, segmental or circular bearing
surface c formed on or connected to the triangular or other shaped pressure bar B or
The necessary pressure being put on the top cutting plate A by means of
the thumb screw e as usual.
vice versa.
In Figs. 3 and 4 which are part sectional elevations we have shewn our improve-
ments as applied to sheep shearing machines. D is the top cutter which is held in
position by the fork or other shaped pressure bar E, and F is the bottom plate or comb.
The other end of the said pressure bar E (see Fig. 3) is supported by means of one or
more flat headed pins or T shaped oscillators or cone or triangular shaped pieces or their
equivalents for diminishing the friction in the to and fro motion of the pressure bar E,
but by preference we use only one T shaped oscillator G as shewn, in an upright position,
the point or axis e which is round bears against the underside of the said pressure
bar E or takes into a hole, slot or recess formed on or inserted in the said pressure
bar E for that purpose, while the flat part for head of the T shaped oscillator G bears
upon the convex, globular, segmental or circular shaped bearing surface formed on or
inserted in the body or frame H of the machine. I is the centre pin or axis on which
the pressure bar E works or oscillates, the said pressure bar E being actuated by cam
or other suitable mechanism. On the top of the centre pin or axis I we place a corded
nut g for putting the necessary pressure on the pressure bar E.
In Fig. 4 we have shewn the Ṭ shaped oscillator G resting on the top of the
pressure bar E, with its point or axis e which is round bearing upon or taking into a
hole, slot or recess formed on or inserted in the said pressure bar E for that purpose,
whilst the flat part for head of the said T shaped oscillator G bears upon the convex,
globular, segmental or circular shaped bearing surface formed on or inserted in the
underside of the adjusting cap; which is screwed into the top of the body or frame H
of the machine and by which means the necessary pressure is put upon the pressure
bar E. On the rear end of the said pressure bar E we form a boss or shoulder

page_text: which rests upon the body or frame H of the machine, the said boss or shoulder /
forming a support for the rear end of the pressure bar E. The pin i which passes
through the boss or shoulder h forms the axis on which the pressure bar E works or
oscillates, the said pressure bar E being actuated by cam or other suitable mechanism.
Fig. 5 is an enlarged view of the T shaped oscillator and Fig. 6 shews a different
shaped oscillator.
The top and bottom surfaces on which the said T shaped oscillator or oscillators
bear may both be formed of a globular, convex, segmental or circular shape or their
equivalent, having a suitable oscillating piece or pieces inserted between them for the
same purpose.
We may when desired cover the ☐ shaped oscillator or oscillators or their
equivalents in such a manner as to effectually prevent any dirt or dust entering
between the bearing surfaces.
Having now particularly described and ascertained the nature of our said inven-
tion and in what inanner the same is to be performed we would have it understood
that we do not confine ourselves to any particular shaped oscillator as any convenient
form suitable for making a rocking or oscillating movement may be employed, but
what we claim is :-
Firstly-In a shearing or clipping machine the use of one or more flat headed
pins or studs or cone, triangular or T shaped pieces or their equivalents in combina-
tion with one or more convex, globular, segmental or circular shaped bearing surfaces
or their equivalents for diminishing the friction on the cutting plate or plates
substantially as herein described and shewn in Figs. 1 and 2.
Secondly-In a shearing or clipping machine the use of one or more flat headed
pins or studs or ccne, triangular or T shaped pieces or their equivalents in combination
with one or more convex, globular, segmental or circular shaped bearing surfaces or
their equivalents for diminishing the friction on the pressure bar E or its equivalent
substantially as herein described and shewn in Figs. 3 and 4.
Thirdly The means substantially as herein described and shewn for reducing
friction in shearing and clipping machines.
