Improvements in Machines or Appliances for Shearing or Clipping
Wool, Hair, or other like Material or Substance.
We, WILLIAM Bowx, of 308 Summer Lane, Birmingham in the County of
Warwick, Manufacturer and GEORGE CAPEWELL, of 114, Upper Thomas Street,
Aston juxta Birmingham aforesaid, Machinist, do hereby declare the nature of this
invention to be as follows:-
This invention relates to machines or appliances for clipping or shearing wool,
hair or other like material or substance which are usually driven by motive, com-
pressed air or other power, the objects of which are to provide improved means for
actuating the top cutting plate or plates in their to and fro motion across the
bottom comb or plates and for putting the necessary pressure upon the parts
employed for that purpose..
Our improvements consist in pivoting or jointing a short arın or lever to the
frame or body of the machine, the said arm or lever being actuated by link, swivel,
crank or other suitable means, but by preference we recess or slot one end of the
said arm or lever and secure therein a small swivelled piece the other end of the
said small swivelled piece being formed with a hole or recess which said hole or
recess is made to work upon a sinal loose roller or ball or other suitably shaped
piece connected eccentrically to the spindle or other part which gives motion to the
machine, or when desired we may dispense with the small swivelled piece and use
the recessed or slotted arm or lever in combination with the loose roller or ball or
other suitably shaped piece which is connected eccentrically to the spindle of the
machine. On the other end of the said arm or lever is formed a clip, peg or peg
and roller combined or other suitable connection which takes into or is attached to
a forked or other shaped pressure bar or cutter carrier or vice versa, the said
pressure bar or cutter carrier being so formed as to allow one end to bear upon the
cutting plate or plates, whilst the other end bears upon a ball or other suitably
shaped piece or its equivalent connected to the body or frame of the machine or
vice versa, or it may be so formed as to take into or upon the inside or outside of the
top or bottom part of the pivot which the said arm or lever works upon or any part
connected therewith; or the end of the said pressure bar or cutter carrier may be
so formed as to take into or upon the said arm or lever or upon any other bearing
piece or pieces which may be inserted or hinged or pivoted or jointed to the said
arm or lever for that purpose and which will give to the said pressure bar or cutter
carrier a free bearing axis. The end of the pressure bar or cutter carrier which
presses upon the plate or plates is preferably formed with three bearing parts any
one of which may be made with sufficient flexibility to ensure perfect contact with
the cutting plate or plates when pressed upon. The said arm or lever may have
small rollers or steel balls or other antifrictional means applied to the wearing
parts if desired.
In applying our improved means for putting the necessary pressure upon the
cutting plate or plates we use by preference one or more of our oscillators (for
which Letters Patent were granted to us on the 26th day of January A.D. 1885
No. 1107) which are held in position by the usual adjusting screw, to which we
apply an adjustable lock-nut or collar for preventing the same from working loose.
The said oscillators are either in direct contact with the said pressure bar or cutter
carrier or in combination with a flexible spring bearing piece or pieces or their
equivalent, one end of the said flexible bearing piece resting upon the pressure bar
or cutter carrier whilst the other end is formed so as to take into or upon the top
part of the centre pivot of the arm or lever or other suitable bearing part formed

page_text: for that purpose, or the pressure bar or cutter carrier may be made flexible, or a
flexible part attached thereto, by this means we lessen the amount of pressure and
obtain a more even working of the cutting plate or plates when in action. Instead
of using oscillators for putting pressure on the necessary parts we may when desired
use an adjustable clamping piece or pieces preferably attached to the body or
frame of the machine and in direct line with the centre of the arm or lever pivot.
When using this method we attach to any convenient part of the machine but
preferably to the centre pivot inside or outside a small crank lever or other shaped
swivel or swing piece for the purpose of supporting one end of the pressure bar or
cutter carrier or flexible spring bearing piece or pieces or their equivalent, whilst
the said adjustable clamping piece or pieces are so formed for putting the necessary
pressure on the parts and also as an axis for the pressure bar or cutter carrier to
work upon, or we may support the end of the cutter carrier or pressure bar or
flexible spring bearing piece or pieces or their equivalent by means of the centre
pivot as before and use the said small crank lever or other shaped swivel or swing
piece which is attached to the centre pivot or to the body or frame of the machine
for carrying an adjustable clamp or screw or we may dispense with the said small
crank lever or other shaped swivel or swing piece and secure the clamp or screw to
the short arm or lever, the said clamp or screw passing through the pressure bar or
cutter carrier or flexible spring bearing piece or pieces or their equivalent or the
said clamp or screw may be attached to the pressure bar or cutter carrier or flexible
spring bearing piece or pieces or their equivalent and pass through the short arm
or lever, the necessary pressure being obtained by means of a thumb screw or lock
The centre pivot of the short arm or lever may be formed with a loose collar
so that it can easily be replaced when worn out. .

Improvements in Machines or Appliances for Shearing or Clipping
Wool, Hair, or other like Material or Substance.
We, WILLIAM Bown, 308, Summer Lane, Birmingham in the County of
Warwick, Manufacturer and GEORGE CAPEWELL, 114 Upper Thomas Street,
Aston, juxta 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 :-
This invention relates to machines or appliances for clipping or shearing wool,
hair or other like material or substance which are usually driven by motive, com-
pressed air or other power the objects of which are to provide improved means for
actuating the top cutting plate or plates in their to and fro motion across the
bottom comb or plates and for putting the necessary pressure upon the parts
employed for that purpose.
In order that our invention may be better understood we have annexed the
.tccompanying sheet of drawings.
Fig. 1 is a part longitudinal section of so much of a sheep shearing machine as is
necessary to illustrate our invention.
Fig. 2 is a part sectional plan view of same.
Fig. 3 is a similar view to Fig. 1 shewing another method of our improvements.
Fig. 4 is a part sectional plan view of same.
Fig. 5 is a similar view to Figs. 1 and 3 shewing our improvements when dis-
pensing with the oscillator, and
Fig. 6 is a part sectional plan view of same.
With reference to Figs. 1 and 2 A is a short arm or lever which is pivotted at a
to the body or frame B of the machine, the said arm or lever A is actuated by a

page_text: link, swivel, crank or other suitable means, but by preference we recess or slot one
end of the said arm or lever A and secure therein a small swivelled piece C, the
other end of the said small swivelled piece C is formed with a hole or recess which
said hole or recess works upon a ball headed stud D or roller or other suitably
shaped piece connected eccentrically to the spindle E or other part which gives
motion to the machine. On the other end of the said arm or lever A is formed a
clip F, or peg or peg and roller combined or other suitable connection, which said
clip F takes hold of or is attached to a forked arm or other shaped pressure bar or
cutter carrier G, or vice versa; the said pressure bar or cutter carrier G is so
formed as to allow one end to bear upon the cutter or cutting plate H which moves
to and fro across the comb I, whilst the other end of the said pressure bar or cutter
carrier G bears upon the pivot bor ball or other suitably shaped piece or its
equivalent connected to the short arm or lever A or vice versa, or to the body or
frame B of the inachine or vice versa. Or the end of the said pressure bar or cutter
carrier G may be so formed as to take into or upon the said arm or lever A or
upon any other bearing piece or pieces which may be inserted, hinged, pivotted or
jointed to the said arm or lever A and which form a free bearing axis for the said
pressure bar or cutter carrier G. The end of the pressure bar or cutter carrier G
which presses upon the cutter or cutting plate H is preferably formed with three
bearing parts or forks any one of which may be made with sufficient flexibility to
ensure perfect contact with the said cutter or cutting plate H when pressed upon.
Steel balls c or small rollers or other antifrictional means may be applied to the
wearing parts of the arm or lever A if desired.
In applying our improved means for putting the necessary pressure upon the
cutter or cutting plate H we use by preference one or more of our oscillators J (for
which Letters Patent were granted to us on the 26th of January 1885, No. 1107)
which are held in position by the usual adjusting screw K, an adjustable lock-nut L
or collar being provided for preventing the said adjusting screw K working loose.
The said oscillator J bears upon a spring M or bearing piece or pieces or equivalent,
one end of the said spring M rests upon the pressure bar or cutter carrier (, whilst
the other end is formed so as to swivel on the top part of the centre pivot a of the
arm or lever A or other suitable bearing part formed for that purpose; or the
spring M may be attached to or form part of the said pressure bar or cutter
carrier G; or we may form the spring M so as to use it as a pressure bar or cutter
carrier and dispense with the said pressure bar or cutter carrier G; by this means
we lessen the amount of pressure and obtain a more even working of the cutter or
cutting plate H when in action.
In Figs. 3 and 4 we have shewn another method for actuating the top cutter or
cutting plate H. In this case we dispense with the small swivelled piece C and use
the recessed or slotted arm or lever A in combination with a loose roller N or ball
or other suitably shaped piece which is connected eccentrically to the balance
crank O; the said balance crank O being connected to the spindle E or other part
which gives motion to the machine. On the other end of the said arm or lever A
is formed a peg d which takes into a hole formed in the pressure bar or cutter
carrier G or rice versa. One end of the said pressure bar or cutter carrier G bears
upon the cutter or cutting plate H as previously described, whilst the other end of
the said pressure bar or cutter carrier G oscillates or bears upon the pivot e or ball
or other suitably shaped piece or its equivalent connected to the body or frame of
the machine or vice versa, or the end of the said pressure bar or cutter carrier G
may be so formed as to oscillate or bear upon the inside or outside of the top or
bottom part of the pivot a which the arm or lever A works upon, or any part con-
nected therewith.
When applying the necessary means for putting pressure upon the cutter or -
cutting plate H we use the oscillator J which bears upon the pressure bar or cutter
carrier G, the said oscillator J is held in position by the usual adjusting screw K,
an adjustable lock-nut L being employed as previously described.

page_text: In Figs. 5 and 6 we have shewn our improvements when dispensing with the
oscillator J. In this method we attach to any convenient part of the machine but
preferably to the inside or outside of the centre pivot a on which the arm or lever A
works, a small crank lever for other suitably shaped swivel piece or its equivalent
for the purpose of supporting one end of the pressure bar or cutter carrier G, or a
spring or flexible bearing piece or pieces or equivalent, the other end of the said
pressure bar or cutter carrier G bears upon the cutter or cutting plate H as pre-
viously described. In order to put pressure on the necessary parts we place a steel
ball or roller or peg or other suitable bearing piece or pieces on the top of the
pressure bar or cutter carrier G and directly over the centre pivot a of the arm or
lever A; the usual adjusting screw K and adjustable lock-mit L being employed
for that purpose; the said steel ball or equivalent forming an axis for the pressure
bar or cutter carrier G to work upon. Or the bearing piece or its equivalent may
be attached to or form part of the adjusting screw K. The centre pivot a of the
arm or lever A. may be formed with a loose collar or its equivalent so that it can
easily be replaced when worn out.
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 exact details as herein shewn and described
but what we claim is :-
Firstly In a sheep shearing or clipping machine the use of the short arm or
lever A. in combination with the pressure bar or cutter carrier G for the purpose
substantially as herein shewn and described.
