Improvements in or connected with Calf Inflators and the like.
GEORGE HERBERT, of 6 and 7 West Smithfield London E.C. Scale Maker and
Cutler, do hereby declare the nature of my said invention to be as follows:-
My invention relates to improved means and appliances for the inflation of
calves and other animals with air and preservative materials or fluids, when being
dressed for food.
According to my invention I construct an improved combined tubular nozzle and
needle, which can be inserted under the skin of the animal. The needle end of the
apparatus is tapered and perforated, and the end is cut diagonally to facilitate the
penetration of the skin. The outer end of the apparatus is furnished with a
number of annular, elliptical, oval or otherwise shaped bosses or projections, at
equal or unequal distances apart, upon or over which the skin is stretched, for
facilitating the formation of an air-tight junction. I sometimes fit a screw washer
so that the skin may be firmly gripped between the washer and an annular surface
formed upon one of the bosses, as an additional security to that of the grip of the
hand upon the skin extended over the bosses, to render the joint air-tight. I also
fit a non-return valve to the apparatus to prevent the return of the air after the
inflation of the calf or other animal.
I also sometimes form a chamber in the nozzle for the reception of a moist or
dry preservative material the properties of which may be carried into the animal
in the form of spray, powder, or medicated air.
My invention may be used with any air-pump or inflator, but I prefer to use
the ordinary pump used in the inflation of the rubber tyres of cycles &
footballs.

COMPLETE SPECIFICATION.
Improvements in or connected with Calf Inflators and the like..
I, GEORGE HERBERT, of 6 and 7 West Smithfield, London E.C., Scale Maker
and Cutler, 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 :-
My invention relates to improved means and appliances for the inflation of
calves and other animals with air and preservative materials or fluids, when being
dressed for food.
According to my invention I construct an improved combined tubular nozzle and
needle, which can be inserted under the skin of the animal. The needle end of the
apparatus is tapered and perforated, and the end is cut diagonally to facilitate the
penetration of the skin.
And in order that my said invention may be particularly described and ascertained,

page_text: reference is hereby made to the accompanying drawings, in which similar figures
of reference indicate corresponding parts.
Fig. 1 is an elevation of an inflator with one of my improved detachable nozzles
attached thereto.
Figs. 2 to 7 show various other forms of nozzles adapted for use with my
invention.
Referring to Fig. 1-The butt-end 8 of the air pump 9 is fitted with a handle 10,
formed of wood, or other non-conducting material, whereby the heat arising from
the working of the pump is prevented from reaching the hand. 11 is the needle
end of the apparatus, which is tapered at 11 by a diagonal cut, as shown, to
facilitate the perforation of the skin. 12, 12, are annular projections formed upon
the nozzle 11, for facilitating the formation of a practically air-tight junction.
22 are stops to prevent the piston being drawn too far.
In Fig. 2 the nozzle 11 is shown formed with diagonal flanges or projections 13,
which stretch and form air tight joints with the skin of the animal.
In Fig. 3 the nozzle 11 is shown formed with a helical projection or worm 14,
which can be inserted under the skin and screwed into the space between the skin
and the flesh, forming an air tight joint.
In Fig. 4 the nozzle is shown formed with projections 15, which engage with
and raise the skin, and assist in forming an air-tight joint, when inserted under the
skin.
In Fig. 5 the nozzle is shown formed with similar projections 15 on one side
only.
In Fig. 6 the nozzle is shown formed with a screw thread 16 of uniform pitch ;
and in Fig. 7 a conoidal nozzle is shown formed with a screw thread 17, of
increasing pitch.
18 is an opening, fitted with a screw cap, for forming a connection with a cold-
air chamber, whereby cold air may be drawn into the pump and forced into the
meat at any part desired.
19 is a non-return valve, which is fitted to the rear end of the nozzle to prevent
the return of air into the pump after being forced into the animal.
In Fig. 7 a chamber 20 is shown, fitted to the rear end of the nozzle, for the
reception of a moist or dry preservative and coloring material or fluid, the
properties of which are carried into the animal in the form of spray, powder, or
medicated air.
or
My improved nozzles are sometimes formed with small holes 21 for the passage
of air between the nozzle and the skin of the animal, in addition to the
opening at 11ª. I also sometimes fit a screw washer to the nozzle, so that the skin
may be firmly gripped between the washer and an annular surface formed upon one
of the bosses, as an additional security to that of the grip of the hand upon the
skin, extended over the bosses, to render the joint air-tight.
In using the apparatus, the nozzle is inserted under the skin of the animal,
the perforation being facilitated by the sharp tapered form of the needle at 11ª;
no previous puncture being required. After inflation the nozzle may be detached
and left under the skin until the animal is cold and the meat set.
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. In appliances for the inflation of calves and other animals the application
and use of a nozzle formed with projections 12, in combination with a tapered
needle 11 formed with a cutting end 11ª for insertion under the skin of the animal,
the perforation being facilitated by the sharp tapered form of the cutting needle,
the particular conformation of the needle and nozzle forming practically an air-tight
joint or junction, substantially as herein before described and illustrated by Fig. 1
of the drawings.

page_text: 2. In appliances for the inflation of calves and other animals, the combination
of a dead end 10 to the air-pump barrel, formed of non-conducting material, and a
passage or connection 18 for connecting the barrel 9 with a cold-air chamber,
substantially as herein before described and illustrated by Fig. 1 of the drawings.
3. In appliances for the inflation of calves and other animals, the application
and use of nozzles formed with bulb, worm like and other projections 13, 14, 15
and 16, in combination with a tapered needle 11 with a cutting end 11ª, substantially
as herein before described and illustrated by the drawings.
or
4. In appliances for the inflation of calves and other animals, the application and
use of a chamber 20, for the reception of a moist or dry preservative and coloring
material or fluid, substantially as and for the purposes herein before described and
illustrated by Fig. 7 of the drawings.
5. In appliances for the inflation of calves and other animals, consisting of a
barrel fitted with a non-conducting handle and inlet union, a nozzle having a tapered
and cutting needle-end and check valve the combination therewith of annular,
diagonal, bulb, screw, worm-like and other projections and formations, substantially
as and for the purposes herein before described and illustrated by the drawings.
