Improved Mechanism for Use in Blowing and Expanding the
Carcasses of Calves and other Animals.
We HERBERT STONE of Bracebridge Street, Manufacturer and FREDERICK
WILLIAM RUSHBROOKE of 56 Charlotte Street, Merchant both of Birmingham
in the County of Warwick do hereby declare the nature of this invention to be as
follows:-
This invention consists in the combination and arrangement of the parts herein-
after described forming and constituting improved self-contained mechanism
suitable for use in blowing and expanding carcasses of calves and other animals.
In carrying out our invention we provide an air-pump formed from a cylindrical
tube, within which is placed a piston connected to a tube or connecting rod, one
end of the pump tube would be covered permanently and the other end would be
fitted with a detachable cover through which would pass the hollow piston rod,
such parts would form an air-pump and such parts in themselves are not new and
original.
We next provide a tapered plug shaped nozzle, the transverse section of which
would by preference be round; the periphery of the tapered nozzle would be scored
so as to form a series of flanges or steps, the advantage of which will be hereinafter
set forth.
The tapered nozzle would be provided with a central passage; beyond the root
end of tapered nozzle would extend a branch of suitable length; we next provide
an elbow piece such as is used in the make up of gas-fittings and screw, braze,
solder, or otherwise connect the root end of the nozzle to one branch of the elbow,
we next connect the other branch of the elbow to the end of hollow pump connecting
rod, the nozzle would in some cases be pierced through its entire length with a
clearance hole; in other cases the passage through the nozzle would be provided
with a seat-bearing or with seat-bearings, within which would be placed a valve or
valves to prevent the air returning into pump barrel.
In addition to the peripheral steps provided on the nozzle we in some cases
groove the outer periphery of the nozzle across the steps; in other cases we in
lieu of the parallel steps we provide a worin or thread on the outer periphery
of the nozzle.
In using our improved mechanism the step nozzle would be introduced into the
flesh of a calf or other dead animal or into a vein, or secured within the flesh in
such a manner that the air forced through the nozzle by means of the pump would
expand the carcass and not escape back at the point where introduced.
We are aware that a combined air-pump and nozzle has been in use by butchers
to expand carcasses, therefore we do not claim the exclusive use of an air-pump and:
nozzle for blowing up. meat.
The combination of either modification of nozzle as hereiu described with an:
air-pump forms and constitutes a new combination and a new article of commerce,.
and such new combination constitutes our invention.

We HERBERT STONE, of Bracebridge Street, Manufacturer and FREDERICE
WILLIAM RUSHBROOKE of 56 Charlotte Street, Merchant, both of Birmingham
in the County of Warwick do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described an
ascertained in and by the following statement:-
This invention consists in the combination and arrangement of the parts herein
after described forming and constituting improved self-contained mechanism
suitable for use in blowing and expanding carcasses of calves amil other animals.
We will now proceed to describe with reference to the accompanying drawing
the manner in which our invention is constructed and used.

In carrying out our invention we provide the cylindrical pump-tube a as shew
at Figures 1 and 8, within which is placed the piston b as shewn in position
Figure 8, and as shewn in detail at Figure 16, the piston 6 is connected to piston
tube e by threading the external surface of the tube into the internal threade
neck of piston b.
One end of the pump-tube a is covered permanently by means of the cap
such cap d being compressed over, brazed over or otherwise secured to th
barrel-pump. The front end of the pump-tube or pump-barrel a is fitted wit
a detachable cover e as shewn connected at Figure 8 and as shewn in deta
at Figure 6, through which passes the hollow piston-rod or piston-tube
such parts in themselves are not new as parts of au air-pump, the novel an
inventive part consists in the specific manner in which the parts are combined fo
the purpose described: We next provide a tapered plug shaped nozzle f as shew
connected at Figures 1 and 8 and as shewn in detail at Figure 9, the transvers
section of such nozzle would by preference be round, altho' in some cases we ma
make it oval, or of any other suitable polygonal or curved shape, the periphery
the nozzle is provided with a series of flanges or steps g. The nozzle f is provide

page_text: with a central passage h, beyond the root-end may extend a branch of suitable length,
or we may dispense with the separate straight branch and provide an elbow-piece as
shewn at k Figures 1 and 8, and as shewn in detail at Figure 2. We connect the
root-end of nozzle to one branch of elbow k and next connect the other branch of
elbow to the end of pump connecting tube c, the connection may be made by means
of screw-threads as illustrated or it may be made by the process of soldering,
brazing, compressing or by other suitable means. The nozzle would in some
cases be pierced through its entire length with a clearance hole h, in other cases the
passage through the nozzle would be provided with a seat-bearing as shewn at m
Figure 13 within which would be placed a valve n governed by a spring o.
In addition to the peripheral steps g, we in some cases groove the outer surface
of nozzle as shewn at p on the detail drawing views Figures 11 and 12.
In other cases we provide a worm or thread as shewn at q on the detail view
Figure 15. The sleeve r consists of a short piece of tube slipped over the piston-
tube and secured to the end of piston-tube and to the tube c by a film of solder or
by compressing, or by other suitable means, the ends of sleeve r forms a stop to
regulate the travel of the piston 6 within the barrel a.
We provide a valve-seat-bearing t as shewn in position at Figure 8, and as shewn
in detail at Figures 18 and 19, through which is passed the air-valve u, such valve
being in some cases governed by a spiral-spring v.
In using our improved mechanism, the stepped or screwed nozzle would be
introduced into the flesh of a calf or other dead animal, or into a vein, or secured
within the flesh in such a manner that the air forced through the nozzle by means
of the pump would expand the carcass and not escape back at the point where
introduced.
In some cases we dispense with the elbow and screw the nozzle f direct onto
the end of piston-tube c. In other cases we connect the end of flexible tube to
the piston-tube c and the other end of such flexible tube to the root-end j of
nozzle.
Having now particularly described and ascertained the nature of our said inven-
tion and the manner in which the same is to be performed, we declare that what we
claim is:-
1st. The invention as illustrated and described for the purpose described.
2nd. The making of a pamp for use in blowing and expanding carcasses by the
combination of an external metal pump-tube with an internal piston and hollow
piston-rod in conjunction with an elbow-piece nozzle and valve or valves as illustrated
and described in relation to Figures 1 to 21 of accompanying drawings.
3rd. In a calf-blowing pump the use of a nozzle of the kind described in relation
to Figure 9 secured direct to the piston-tube of pump.
4th. In a calf-blowing pump the use of a nozzle of the kind described in relation
to Figure 9 in combination with a flexible tube attached to metal piston-tube of
pump.
