I HARRY BURGON of the La Plata Works Malin Bridge Sheffield in the County of
York Clerk do hereby declare the nature of this invention to be as follows:-
The object of the Invention is to prevent or greatly deaden the constant clicking
and noise arising through the coming together and concussion of the ordinary stop
portions of the blades of sheep shears when being used, as well as to obviate the very
painful jarring and stunning of the muscles of the hands wrists and arms of the
shearers, objections which have been much complained of, many shearers' hands being
swollen and knocked up with a few hours working of the description of shears
heretofore in use.
According to my improvements,-in or to the inside of the shank of each shear
blade I apply, and secure by rivetting or otherwise, a brass or other suitable metal
stop which is tubular, or is recessed, to receive and securely hold a plug made of
india rubber, leather, cork. or of other suitable yielding material.
These metal stops are slotted in each side so as to facilitate the ready removal of the
plugs therefrom when required to be renewed. The stop in the shank of one blade is
inserted exactly opposite to the stop in the other shank; and the effect of using shears
having these stops attached, and the plugs therein meeting, will be to greatly deaden
or prevent the constant objectionable clicking or noise now so much complained of in
using shears as hitherto constructed.
In making shears having these stops fitted thereto, the usual stops with which the
heels of the shear blades are now formed are entirely dispensed with, that is,-
according to my invention the heels of the blades are not turned or curved up, thus
making the former kind of stops, but are made straight.

page_text: Improvements in or Connected with Sheep Shears.
I HARRY BURGON of the La Plata Works Malin Bridge Sheffield in the County of
York Clerk do hereby declare the nature of this invention and in what manner the
same is to bo performed, to be particularly described and ascertained in and by the
following statement in writing, and on-reference to the accompanying sheet of
drawings
:-
The object of and attained by my invention, is, the provention or the greatly
deadening of the constant clicking and noise arising through the coming together and
concussion of the ordinary stop portions of the blades of sheep shears when being
used, as well as to obviate the very painful jarring, and also the stunning of the
muscles of the hands wrists and arms of the shearers; many shearers' hands having
been swollen and knocked up or tired out with a fow hours using or working the
description of sheep shears heretofore generally used.
In order that the carrying of my invention into practice may be fully understood it
is illustrated on the accompanying sheet of drawings, on which Figure 1, represents a
pair of sheep shears with my improvements applied thereto, and Figure 2, is a view
of my silently acting stop, shown separately and of full size, before being fixed in its
place. The letters of reference on the drawing correspond with those in the following
description.
According to my improvements I make and apply, in or to the inside of the
shank a, of each shear, a brass or other suitable metal tubular stop b, which stop I
call a silently acting stop. This stop I fit into the shank a, and secure or fasten it
thereto either by rivetting the closed end c, of the stop (See Figure 2,) by a single
rivet to the shank, or I punch or bore a hole through the shank, then pass the closed
end through it, and I rivet or securely fix it in by pressure, or I screw it into the
shank, so as to effectually prevent the stop from moving or turning or working loose.
The stop b, which is tubular is recessed or hollowed out to receive and securely hold a
plug d, mado of indiarubber, leather, cork, or of other suitable yielding material. The
tops of the plugs protrude a little above the tops of the stops as shown in Figure 1.
The stops b, are slotted or cut in each side, one of the slots being shown at in
Figures 1, and 2; this is done in order to facilitate the ready insertion and the
removal of the plugs d, when they are required to be renewed or moved.
e,
The stop in the shank of one blade of a pair of sheep shears is inserted and fixed
exactly opposite to the stop in the other shank.
The effect of using sheep shears having these silently acting stops attached, and the
plugs therein meeting is to greatly deaden or entirely provent the constant and
objectionable clicking or noise so much complained of in using shears as hitherto
constructed with the ordinary kinds of stop portions formed on the heels of the blades
themselves.
In making sheep shears with these silently acting stops attached thereto, the usual
or old kinds of stops with which the heels of the shear blades have been formed are

page_text: entirely dispensed with, that is, according to my invention the heels of the shear blades
are not turned or curved up thus making the former kind of stops, but they are made
straight, or as shown at f, in Figure 1.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
1. The application to, and use with, sheep shears of silently acting stops preventing
the noise and jarring resulting from the use of sheep shears having the old kinds of
stops formed therein,-substantially as hereinbefore described, and as illustrated on
the accompanying drawing.-And,
2. Dispensing with the stops as hitherto made by turning or curving up the heels
of the shear blades,-as herein before described.
