Complete Specification Left, 2nd Sept., 1889-Accepted, 12th Oct., 1889
PROVISIONAL SPECIFICATION.
Apparatus for Blowing Calves.
I HENRY HEALE Hareston Ash Hill Road Torquay Devon Coachman do hereby
declare the nature of this invention to be as follows:-
An instrument for blowing air into the carcasses of Calves (before skinning) which
can in this way be done far quicker, more easily, and in a more wholesome manner, than
with the mouth, which is the Butcher's practice at present; also without skewering,
and veal blown by this Invention is whiter and will keep longer.
The Instrument consists of an Air Pump A (see Drawing) Handle of Piston
(or sucker). B. Piston with holes for admitting and expelling air, and Valve for
preventing escape of air.
C. Cover, which screws on cylinder D.
D. Cylinder with E. hole for admitting air.
Next portion is a pipe (with F. G. H. 1. K.) to be detached from Cylinder D.
as soon as the Calf is blown, and left in the skin till the carcass is opened.
F. Tap, to keep the air in when the blowing is finished.
G. Valve inside to keep air from returning while blowing.
H. Is for screwing I. tight to K.
I. Plate with leather, which fits down to K, when in use, outside the skin.
K. Plate to go (through a small slit) under the calf's skin, with I pressed tight
over it by means of H.
This Portion F. G. H. I. K. without the air Pump can be fastened to Bellows
and used in the same manner.
COMPLETE SPECIFICATION.
Apparatus for Blowing Calves.
I, HENRY HEALE Hareston Ash Hill Road Torquay Devonshire Coachman 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 is for blowing air into the carcasses of Calves before skinning,
which can in this way be done far quicker, more easily, and in a more wholesome
manner than with the mouth, which is the Butcher's practice at present, also without
skewering, and the veal blown with this Instrument is whiter, and will keep longer.
As shewn in the Drawings left with the Provisional Specification No. 12984,
Dated 17th day of August 1889 (which I desire to adopt for my complete Specifica-
tion) this Instrument consists, firstly, of an Air Pump, described in Provisional
Specification, as A. Handle of Piston (or Sucker). B. Piston with Holes for admitting
and expelling air, and valve for preventing escape of air.
C. Cover which screws on Cylinder D.
D. Cylinder with E. Hole for admitting air.
Secondly. A Pipe, screwing onto Air Pump Cylinder, with a Tap, which when
turned prevents the air escaping from the Carcass when blown, and a valve inside to
keep air from returning while blowing. At the end of the Pipe there is a Plate to be
passed through a small slit in the Calf's skin, and have another Plate (with washer)
screwed above it by means of a nut, so as to be air tight.

page_text: The Pipe is to be detached from Cylinder of Air Pump as soon as the blowing of
the Calf is finished, the air shut in by means of the Tap, and the Pipe left attached to
the skin till the carcass is opened and cut up.
This Portion (that is the Pipe with Tap &c.) can be attached to Bellows instead of
the Air Pump, and used in same manner, the air being supplied by the Bellows
instead of the Pump.
Explanation of Drawings left with Provisional Specification.
F. Tap to keep the air in when the blowing is finished.
G. Valve inside to keep air from returning while blowing.
H. For screwing I. tight to K.
I. Plate, with leather inside, which fits down to K., when in use, outside the
skin.
K. Plate to go, through a small slit, under the calf's skin with I. pressed tight
over it by means H.
The Veal is by this Invention blown with pure, and cool air instead of with the
warm, and not always pure, breath of a man.
Further, this Instrument can be used by any person, whereas the present custom
of blowing with the mouth can only be managed by a man with strong lungs, the
exertion being very great.
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 that the chief features of novelty are,—
1. Plate on end of Pipe with Hole through it, and movable Plate above with
washer, and Nut to screw down to fix the Calf's skin on bottom Plate.
2. Tap, and Valve inside Pipe and screw for Nut above Plate.
3. Holes in the Piston of Air Pump and Valve, Hole at the bottom of Cylinder to
screw the end of Pipe into, and hole near Top of Cylinder.
Dated this 30th day of August 1880

Of Hareston, Ash Hill Road, Torquay, Devonshire.
