PROVISIONAL SPECIFICATION.
Improvements in Veterinary Surgical Instruments.
CHARLES HENRY HUISHI, 8, Fisher Street, London, W.C., Surgical Instrument
Maker, do hereby declare the nature of this invention to be as follows:-
The improvements proposed have reference to an instrument of American
origin for the artificial insemination of mares cows and other animals, which
instrument has several defects one being that a certain part is made of glass and
another that it has no arrangement for preventing the mucous membrane of
the vagina being drawn into the orifice of the nozzle when sucking up the
seminal fluid. I propose to substitute celluloid for the glass tube used to show
the passage of the semen into the bulb of the syringe which together with part
of the connecting tube is made of rubber. The nozzle which may be made of
vulcanite or celluloid, glass, metal or bone or other material suitable I propose
to guard by means of a shield of wire covering the point and held in position by
a metal band at the base of the nozzle or it may be made to screw or plug on the
point only or the point so covered may be made to screw on the neck of the
nozzle so that in the case of narrow mouthed os uteri there will be no difficulty in
inserting if a plain nozzle point be screwed on the neck which carries the guarded
one. The rubber tube will be flexible, and of suitable length as will be the
nozzle which will be of hard rubber or other suitable material.

Improvements in Veterinary Surgical Instruments.
I, CHARLES HENRY HUISHI, of 8, Fisher Street, London, W.C., Surgical Instru-
ment Maker, 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 has reference to an artificial impregnator designed for the
artificial insemination of mares cows and other animals.
And in order that my invention may be thoroughly understood I now proceed
to describe the accompanying drawing thereof, reference being had to letters
and figures marked thereon.
Fig. 1, is a full length view of the impregnator.

My invention consists a rubber ball a pear shaped with a short neck b into
which the neck d of a clear celluloid cylindrical tube c fits. This tube is pro-
vided with collars d d which accurately fit into the neck and into the end of
the soft india rubber tube e which in turn fits over end f of hard india rubber tube
or nozzle y bored in its entire length terminating at the end with a hole h. Over
this nozzle is fitted a wire guard i held secure upon the shoulder by a collar
of metal split to form a spring clip at k and into which the guard wires i are
fastened..
The capacity of the ball a is about eight ounces, the celluloid tube one and a
half inches the soft india rubber tube seventeen inches, and the hard india rubber
twelve inches but I do not confine myself to exact measurements, shape of ball
nor to celluloid or hard india rubber for the parts of the instrument as other
material may be more suitable.
As the report of the Royal Commission upon horse breeding shows that from
malformation or natural causes forty per cent. of mares are barren in this country
and eminent scientists and veterinarians are of opinion that to counteract this
great loss of stock artificial means should be resorted to.
The operation of artificial insemination is conducted as follows:-The sire
having dismounted from the animal covered the ball of the inseminator is grasped
by the left hand and the air is expelled from it. The nozzle is then taken in the
right hand and with it introduced through the vulva of the animal covered, its
point directed into the pool of semen deposited by the sire into the vagina of
the female; the ball is then allowed to expand and the seminal fluid will be
drawn up through the nozzle and tube and through the clear celluloid may be seen
passing into the bulb. The nozzle is now inserted through the cervix uteri for
about four inches the ball compressed and the semen expelled into the uterus
there to fertilize the ovum expelled from her ovaries by the female. Providing
another animal or animals is in aestum and it is desired to inseminate her the
semen remaining within vagina of the covered animal may be taken up by the
inseminator and placed into their uterus's with the result that they also produce
offspring and the vitality of the sire is thereby husbanded.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
:
1. The impregnator substantially as fully described in the above Specification
and illustrated in the accompanying drawing.
2. Originality of design in nozzle and wire guard as described in Specification
and in the substitution of clear celluloid for glass (which might break in use and
cause wounds) in the tube. Improvements in veterinary surgical appliances for
use in the artificial insemination of animals which by their use the percentage of
progeny produced is largely increased and the vitality of sire husbanded in a
large degree, substantially in the manner and for the purpose as herein before
described and set forth in the drawings.
