I HENRY HARRIS LAKE of the firm of Haseltine Lake & Co Patent Agents
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN APPARATUS FOR CLIPPING HORSES, SHEARING
SHEEP, AND SIMILAR PURPOSES to be as follows:-
"
This invention relates to important improvements in the mounting of apparatus
for clipping horses, shearing sheep, and similar purposes.
These improvements consist in effecting the complete mounting of the apparatus
or tool by means of two bolts only, and dispensing with screws or other fastening
devices which have been heretofore employed for this purpose.
One of the bolts connects the fixed handle, which is in one piece with the
pressing plate, to the movable handle; the other bolt unites the two combs (the
fixed and the movable) with the pressing plate.
The removal of the latter bolt separates the two combs from the handles and
from the pressing plate, and the removal of the other bolt disconnects the two
handles.
It is evident that this mode of fastening is independent of any particular
construction of the clipping or shearing tool or apparatus, and that it can be
applied to various kinds of tools of this class with the same facility.
"
In order to explain the details of the invention of which I have just given the
outline, I have represented in the accompanying drawing a pair of "Clark
clipping-shears, to which my system of mounting is applied.
Figure 1 is a front elevation of the said clipping shears.
Figure 2 is a section of the same taken through a plane perpendicular to the
combs and passing through the lino 1-2, Figure 1.
In these Figures the same letters of reference indicate corresponding parts.

arm c is connected with the arm a by a bolt & kept in place, on the one hand by a

movable arm c is composed. The bolt d serves as a pivot or point of articulation
for the two arms a and c.

COMPLETE SPECIFICATION. :
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my invention for "IMPROVEMENTS IN APPARATUS FOR CLIPPING HORSES, SHEARING
SHEEP, AND SIMILAR PURPOSES "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 improvements in apparatus for clipping horses, for
shearing sleep, and for similar purposes.
The said improvements consist in effecting the complete mounting of the
apparatus or tool or the connection of the various parts thereof by means of two
bolts, and dispensing with screws or other fastening devices which have been
heretofore employed for this purpose.
. One of the bolts connects the fixed handle, which is in one piece with the
pressing-plate, to the movable handle; the other bolt unites the fixed and the
movable combs with the pressing plate.

page_text: The removal of the latter bolt separates the two combs from the handles and
from the pressing plate, and the removal of the other bolt disconnects the two
handles.
.
It is evident that this mode of fastening is independent of any particular
construction of the clipping or shearing tool or apparatus and that it can be applied
to various kinds of tools of this class with the same facility.
In order to explain the details of the invention, of which I have just given the
outline, I will refer to the accompanying drawings in which
Figure 1 is a front elevation of a pair of "Clarke" clipping shears showing the
improvements according to this invention applied thereto.
Figure 2 is a section of the same on the line 1-2 Figure 1.
Figure 3. is an elevation of a portion of a pair of shears as seen from the side of
the pressing-plate and illustrating a modification of this invention.
Figure 4 is a side view of the same partly in section.
Figure 5 is a transverse section on the line 1-2 Figure 3.
Referring to Figures 1 and 2 a is the fixed arm of the clippers which is in one
piece with the pressing plate b. The movable arm c is connected with the arm a
by a bolt d, retained in place on the one hand by a pin e and on the other hand by
a head flet into the material of which the movable arm c is composed. The
bolt & serves as a pivot or point of articulation for the two arms a and c.
g is the fixed comb and h is the movable comb. These combs are maintained
in operative contact by the pressing plate b and the bolt i, which passes through
the two combs and the pressing plate. This bolt has a head ; which is located in
a recess in the fixed comb and has a mortise or slot k at its front end in which slot
is introduced the end of a bar held by means of a screw m, whose point bears
against the end of the bolt & which forms a bearing or support for the said screw.
This screw m not only holds the bar in position but serves also for adjusting the
pressure between the plate b and the comb h, and thus between the two combs g
and h. Two pins or screws n which pass through tho pressing plate 6 and whose
points are screwed into the fixed comb g prevent any transverse movement of the
latter.
'
As regards the remainder of the apparatus or tool it does not present any special
features; the movable comb is provided with three rectangular apertures o, p, p, to
permit and limit its play;, through the former passes the bolt i.
The lower prolongation 8 of the said hole receives the end t of the movable
arm c, which imparts alternating rectilinear movement to the movable comb; into
the other two apertures p, p pass the guides r which project from the internal face
of the fixed comb g.
In order to render the operation of the apparatus or tool extremely smooth, for
whatever purposes the latter may be used, that is to say, whether it is applied for
shearing sheep or clipping horses, or used in hair cutting saloons, the following
modification is sometimes made.
This modification is illustrated in Figures 3, 4 and 5 and is applied by way of
example, to a pair of sheep shears.
a is the fixed comb, 6 the movable comb, c the pressing plate, and d the pin
which connects these three pieces. This pin is mortised at its upper part in order
to receive the shank of a bar e which is caused by a screw to exert more or less
pressure upon the plate c, all these parts are the same as those described above, the
changes consisting in the new mode of articulating the two levers.
As shown in Figures 4 and 5, the lever (the prolongation g of which operates
the movable comb,) is recessed on each of its faces so as to present two opposite
conical depressions h, h the apices of which are adjacent to each other. One of
these depressions receives the conical point of a screw i whose head is countersunk
in the material of which the fixed comb a is composed, and the other depression
receives the conical point of a screw; which is located in a tapped hole of the
plate c which is integral with the fixed lever. The slit in the head of the screw j
receives the point of the screw of which presses the two levers upon one another

page_text: and at the same time regulates, as already stated, the pressure of the plate c upon
the comb b and consequently the pressure between the combs.
On the internal face of the plate c are two shoulders & which bear against the
fixed comb a. In this manner the two levers produce no friction upon each other,
and being pivoted upon points, their operation is excessively smooth. When there
is a little play in consequence of the wear of the points, the screw j is tightened a
little, the wear being in this manner immediately compensated for. The pressing
plate c carries on its internal face two guides 7, passing through holes in the
comb b for the purpose of guiding and limiting the motion of the latter. This
arrangement is, however optional and it is evident that the guides can form part
of the fixed comb.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent, I declare that what I claim is
First: In apparatus for clipping horses, and for similar purposes, the complete 1
mounting or connection of the various parts of the apparatus or tool by means of
two bolts only-and-their bar or pin and screw; the said screw serving to regulate
the pressure-of-the-plate-b-upon the two combs-h-as-described and illustrated with
reference to Figures 1 and 2 of the drawings.
Second: The employment of the bar l, which in combination with the screw-m-2
and the bolt i serves to regulate the pressure of the plate 6 upon the two combs h
and between the said combs, as described and represented.
Third: The operating-levers-mounted upon points in combination with the
plate-b-having_two_shoulders-k, which arrangement enables-a-smooth-and easy
operation to be obtained substantially-as-described and illustrated in the
