Year: 1872

page_text: LETTERS PATENT to Bristow Hunt, of No. 1, Serle Street, Lincoln's
Inn, in the County of Middlesex, Gentleman, for the Invention of
"IMPROVEMENTS IN APPARATUS FOR SHEARING OR CLIPPING SHEEP, HORSES,
AND OTHER ANIMALS."-A communication from abroad by Edouard
Wehrlin, of Mulhouse, in Alsatia.
COMPLETE SPECIFICATION filed by the said Bristow Hunt at the Office
of the Commissioners of Patents, with his Petition and Declaration,
on the 24th June 1872, pursuant to the 9th Section of the Patent
Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BRISTOW
HUNT, of No. 1, Serle Street, Lincoln's Inn, in the County of Middlesex,
Gentleman, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
APPARATUS FOR SHEARING OR CLIPPING SHEEP, HORSES, AND OTHER ANIMALS,"
and have petitioned Her Majesty to grant unto me, my executors,

page_text: administrators, and assigns, Her Royal Letters Patent for the same,
and have made solemn Declaration that it is a communication from
Edouard Wehrlin, of Mulhouse, ‘in Alsatia.
NOW KNOW YE, that I, the said Bristow Hunt, do hereby declare
that the following Complete Specification, under my hand and seal, fully
describes and ascertains the nature of the said Invention, and in what
manner the same is to be performed, in and by the following state-
ment, reference being had to the Figures of the accompanying Drawing
and to the letters marked thereon, that is to say :-
The main object of these improvements is to facilitate the single
handed working of shearing or clipping instruments, and to provide for
a more uniform and efficient action of the cutting blades than in
apparatus of this description at present in use.
Figures 1, 2, of the annexed Drawing represent in plan and section
one of the forms of my improved clipper.
A is the ordinary toothed plate secured to the upper end of the
branch B; which is terminated by a spring bend C, prolonged on the
'opposite side by the second branch B'. On the branch B is set the
screw D, on which work the double blade holders E, E³. Each of these
blade holders is slotted at its extremity to give passage to the pressure
levers F, F¹. Each of these levers is terminated at one end by a
projection which bears in a cavity formed in each of the blades L, L',
the other end being traversed by the screw G, G¹, provided with milled
heads and bearing on the blade holders. By means of these screws I
raise or lower the levers F, F', which bearing by their flat ends on the
terminal forks of the blade holders cause the blades to press more or
less closely against the under plate. The blades L, LA, are each provided
with a small catch h, which corresponding with a square hole i maintains
the blades in position. The blade holders are connected with thic
branch B' by means of the bar or arm H, jointed at one end to the
latter by the pivot a, and at the other to the blade holder by the
´screw b:
Figures 3, 4, 5, represent a modification of the arrangement aborc
described, especially designed for small sized instruments to be used in
limb, head, or corner clipping or in finishing off rough work. In this
apparatus the under plate and moveable blade are jointed together by
'means of the square bolt M, and are terminated by finger rings as in

page_text: ordinary scissors. The moveable branch N is provided at its junction
with the under plate with a barrel c traversed by the bolt M, to which is
secured the inner end of a spiral spring R, the outer end being fixed to
the barrel so as to coil when the fingers are brought together, and to
separate the branches by its expansion when the pressure is removed.
The blade holder P making part of the branch N, is of a U section, as
seen in Figure 5, and forms a longitudinal groove (as in Figure 4) in
which is set the tail q of the spring Q. The end of this tail is slotted to
correspond with a circular gorge cut in the adjusting screw T. The
pressure is borne by the screw S, which also serves to press down the
cutting blade.
r is a small spring set in the groove of the blade holder
and tending to separate the blade therefrom causing it to bear on the
lower plate.
I lay no claim to the cutting mechanism of the apparatus shown in
the Drawing, the employment of one or more moveable blades or edges
in combination with a lower dentilated plate being already well known;
but what I claim is,—
1stly. The application to single band clipping or shearing instruments
of spring branches B, in combination with the jointed arm H and the
holders E of ordinary cutting blades and plates L and A, substantially
as herein set forth and shown in Figures 1, 2.
2dly. The application to such instruments of the pressure levers F
and their accessories, substantially as herein set forth and shown in the.
same Figures.
3dly. The construction of such clipping instruments with scissor
branches in combination with a central spring, substantially as herein
set forth and shown in Figures 3, 4, 5, of the annexed Drawing.
In witness whereof, I, the said Bristow Hunt, have hereto set my
hand and seal, this Twenty-fourth day of June One thousand
eight hundred and seventy-two.
BRISTOW HUNT. (L.S.)
