IMPROVEMENTS IN APPARATUS FOR CLIPPING HORSES AND OTHER ANIMALS
Year: 1875

page_text: LETTERS PATENT to Patrick Adie, of Pall Mall, in the County of
Middlesex, Mathematical Instrument Maker, for the Invention of
"IMPROVEMENTS IN APPARATUS FOR CLIPPING HORSES AND OTHER ANIMALS.”
These improvements are as follows:-

page_text: flat or nearly so, in order to form an oil reservoir between the plates,
portions being left on at the sides to prevent the oil from running out,
and a feeding hole may be provided to fill the rescrvoirs, if necessary
The bearing parts of the two plates are to be flat when pressed
together, and the back bearing of the top plate is to be continuous
throughout its length for the purpose of giving greater precision in
preserving the sui faces of these bearings. The plates aro held or pressed
together by means of 3 or more screws, or studs and nuts, in place of
two of such studs or nuts as at present, by which means I obtain tho
power of regulating and preserving the adjustment of the cut more
effectually, and the surfaces are flatter longitudinally.
By means of a series of notches or indentations on the bearing parts
of one or both of the plates, and similar notches or indentations in the
centre of each or both of the top or bottom teeth, the oil is brought more
freely into the rubbing parts.
The three studs may have separate washers, but I prefer to employ
one continuous washer of hard steel or other metal, which continuous
washer is to be hollowed or indented, as above described, with reference
to the plate. The under sides or side of this washer are or is to be
filled with cross cuts or notches, so as to distribute the supply of oil, and
if a further supply is required a small reservoir for oil may be added.
The teeth are to be cut in the same manner as in the Specification of
my said Patent of 30 October 1866, No 2796, that is, tapered in two
directions towards their points and towards their faces, the projecting
points of the under plate being worked in parallel or nearly parallel
portions to act as comb points, with this one difference that I make the
teeth travel over two or more of cach other, having a spare tooth always
on the top plate, so that in cach passage of one tooth to another in any
such movement every under space shall in all cases be crossed by a top
tooth. I also sometimes insert a check stud to take the side strain off
my studs; this may be sold or have a springing tendency.
The fixed handle I form with its end at right angles to its stem, this
and portion being fixed along the back or uncovered portion of the
lower plate, it is screwed or pinned at one end, and fixed by the fulcrum
stud passing through the other end, the other or moveable handle having
its fulcrum on the said stud passing through the end of the short part of
the fixed lever. The driving cam I make solid with the lever. 1 recess

page_text: the top plate slightly at the driving point, so as to keep the fulcrum and
driving point in linc, and also by being solid I get rid of the pin working
loose, as it is otherwise apt to do
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Patrick Adio in the Great Scal Patent Office on
the 19th January 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PATRICK
ADIE, of Pall Mall, in the County of Middlesex, Mathematical Instru-
ment Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of July, in the
year of our Lord One thousand cight hundred and seventy-five, in
the 39th year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Patrick Adie, Her special
license, that I, the said Patrick Adic, my exccutors, administrators, and
assigns, or such others as I, the said Patrick Adic, my executors,
administrators, or assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, usc, excrcise, and
vend, within the United Kingdom of Great Britain and Ircland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
APPARATUS FOR CLIPPING HORSES AND OTHER ANIMALS," upon the condition
(amongst others) that I, the said Patrick Adic, my executors or
administrators, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office withın sıx calendar
months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Patrick Adie, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the accompanying

page_text: plate, as shown in Figure 2, or the

upper plate, as shown in Figure 3.
it presents on its under side the appearance shown in Figure 4,
having its concavity O bounded by a flat margin a, a, at each end by a
flat lip on one side, with cross cuts, notches, or chases 6 for the passage
of the oil from the concavity C to lubricate the rubbing faces, and on
the other side by the flat faces of the cutting teeth. in cach of which is
formed a chase or notch c for the passage of oil from the concavity C to
lubricate the teeth.
When the reservoir is formed in the under plate B, in lieu of in the
upper plate A, the latter is made with a flat face, the oil passages b and c
being in that case formed in the plate B. Oil passages c may however
be formed in both the upper plate and the under plate, if desired, and
both of the plates may be hollowed out, providing that the edges a, a, of
both are left flat.
The plates are held or pressed together by means of three or more, but
preferably by three screws or studs and nuts D in lieu of by two only of
such studs and nuts, as in the usual manner. By these means I am
enabled to more effectually regulate and preserve the adjustment of the
cut, and maintain a flatter and more equal bearing of the one plate or
the other throughout their length.
The three studs may have separate washers, but I prefer to employ
one continuous washer E, the under side of which is by preference like-
wise made concave, or with a longitudinal chase D (as shewn in the
detail under plan, Figure 5) so as to form an oil cavity with transverso
chases e, e, through its side margins for the passage of the lubricant to
the rubbing surface. Od may be supplied through a hole f in the
washer, which hole faces the slot g in the plate A when the handles F, G,
are opened apart, but when these handles are closed together, as in the
position shewn in the Drawing, the washer E serves as a cover to the
slot g, and prevents the escape of the oil. The fixed handle F is formed
with an arm or projection / arranged at right angles to it, and which is
secured to the plate B by a rivet or screw, and by the stud H, which
forms the fulcrum for the other handle G.

Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used
or carried into effect, I would observe in conclusion that what I

page_text: consider to be novel and original, and therefore claim as the Inven-
tion secured to me by the herein-before in part recited Letters Patent
is,―
First. Forming either or both of the plates of such apparatus with a
concavity or recess surrounded by a flat margin, for the purpose of 5
holding between the plates a supply of oil to lubricate the rubbing
surfaces, substantially as herein-before described.
Second. Forming in the teeth of cither or both of the plates and in
the margin of the hollowed plate grooves or chases for the passage of oil
from the concavity or recess above referred to, substantially in the 1
manner and for the purpose herein-before described.
In witness whereof, I, the said Patrick Adic, have to this my
Specification set my hand and scal, the Fourteenth day of
January One thousand eight hundred and seventy-six
