MENTS IN MACHINES FOR SALTING MEAT."
"IMPROVE-
This Invention relates to improvements in machines for salting meat, and espe-
cially to that class in which a pump is used to force brine into the meat through a
perforated sharp pointed nozzle, the pump being combined with a receptacle for
holding the brine.
According to my improvements I form the pump with its valve seatings, complete
in itself, of glass, porcelain, earthenware, or other suitable non-corrosive material.
I also sometimes use for this purpose cast iron rendered non-corrosive by the process
known as that of Professor Barff. The pump is formed complete in itself with the
valve seatings by either moulding or casting, according to the material of which it
is made. For the valves I prefer to use balls of glass or other suitable non-corrosive
material resting in suitable horizontal seatings.
The pump is attached to the bottom of the brine receptacle by screws, Armenian
cement, or other suitable means, and is then immersed in the brine when in use.
It is operated by a lever attached by a pin to the piston rod of the pump, and is
centred at the extremity of its short leverage to a fulcrum suitably attached to the
brine receptacle. The pump may thus be temporarily fixed for use.
The utensil
may either be covered by a lid or not, as preferred. The brine should be strained
before being allowed to pass into the pump. This may be done either by intro-
ducing the brine into the receptacle through a strainer, or by having a strainer
attached to the pump so that the brine is drawn through it into the pump. In the
[Price 6d.1

page_text: latter case provision for the strainer is made in forming the pump. In either case
make the strainer of perforated glass or of perforated or porous earthenware, porce-
lain, or other suitable non-corrosive material, and sometimes form it with the
pump.
The brine receptacle is made of wood, glass, porcelain, earthenware, or other
suitable non-corrosive material.
The piston of the pump is packed with leather, cotton, or cured india-rubber, or
other suitable non-corrosive material may be employed.

by the said Joseph Glover in the Great Seal Patent Office on the 2nd May
1878.

MENTS IN MACHINES FOR SALTING MEAT."
"IMPROVE-
This Invention relates to improvements in machines for salting meat, and
especially to that class of such machines in which a pump is used to force brine into
the meat through and by means of a perforated sharp pointed nozzle, the pump being
combined with a receptacle for holding the brine.
In such machines hitherto made it has been found that the brine corrodes the
pump, thus rendering it undurable, and causing it to leak, and also rendering it
liable to poison the meat impregnated by the brine passed through it (the pump).
According to my Invention I make the pump with its valve seatings complete in
itself, apart from the brine receptacle of earthenware, porcelain, glass, or other
suitable non-corrosible material the pump with its valve seatings being of such a
form that it may be either moulded or cast, according to the nature of the non-
corrosible material of which it is made. Sometimes I use for this purpose cast iron
rendered non-corrosible by the process known as that of Professor Barff. Foi the
valves of the pump I prefer to use balls of glass or other suitable non-corrosible
material resting in suitable horizontal seatings formed in the pump.
The complete pump is attached to the bottom of the brine receptacle, either tem-
porarily by screws, wedges, and slides, or other suitable means, or permanently by
Armenian or other cement, or by other suitable appliance. The pump being thus
immersed in the brine (as it may be in consequence of its non-corrosible nature):
acts with more effect than when placed on top, as in the machines as at present con-
structed, and any slight leakage becomes of no practical importance. There is thus
also no chance of introducing air into the meat, as with present machines such
introduction of air giving a tendency in the meat to decomposition.
The piston of the pump, which may be made of wood or other suitable non-
corrosible material, I pack with cured india-rubber, cotton, leather, or other suitable
material that the brine will not corrode.
And in order that my Invention may be clearly understood and readily carried
into effect. I will proceed to describe it with the aid of the accompanying Drawings,
reference being had to the letters and figures marked thereon and in which Figure 1

page_text: is a longitudiual sectional elevation of a meat-salting machine, constructed according
to my Invention'; Figure 2, a plan; Figures 3 and 4 front and end elevations
respectively of the pump detached, and without showing the piston ;..Figure 5 a
sectional plan taken at the line a, b, Figure 3; and Figure 6, sectional elevation and
plan of the pump piston; Figure 7 is an elevation partly in section of another
form of pump constructed according to my Invention, and Figure 8 is a plan
thereof.
A, Figures 1 to 6, is the pump, which is of the form I have had made in earthen-
ware and found to answer well both for the manufacture and use. It is moulded in.
halves, the two pieces being joined by Armenian or other suitable non-corrosible
cement. The line of the joint is shewn at c, d, Figures 4 and 5, whilst the sectional
view of the pump at Figure 1 shews the face elevation of one of the halves. B, B,
are the glass ball valves resting on seatings formed in the pump, as shewn. C is the
piston packed with cured india-rubber, cotton, leather, or other similar non-corro-
sible material. The top plate of the piston is made adjustable by a screw nut
above, so that the packing may be screwed down and so expanded and tightened.
This is shewn enlarged at Figure 6. D is a white metal non-corrosible socket
screwed into a female screw moulded in the pump, and if necessary also cemented in.
The upper end of this socket receives the. india-rubber pipe E, to the outer end of
which is attached the sharp pointed perforated nozzle F, through which pipe and
nozzle the brine is forced into the meat. G is the hand lever for operating the
pump. It is centred at g to the bracket H, and attached at g¹ to the connecting
rod I, united at its lower end to the pump piston. J is a guide for the lever G.
K is a perforated partition to act as a strainer to strain the brine, which is intro-
duced in the space k, between it and the receptacle L, which latter, as well as the
partition K, are made of earthenware, wood, glass, or other suitable non-corrosible
material. To aid this cement in retaining the two halves of the pump in union, the
upper part thereof are held together by a bolt M passing through the two, the lower
part being also held firmly together by the attachment of the pump to the bottom
of the brine receptacle L. This is effected, as shewn at Figure 4, by bevel slides on
the receptacle and corresponding bevel projections on the pump, cement being run
in between the two. The receptacle may be covered in by a lid if desired.
Figure 7 is an elevation, partly in section, of another form of pump constructed
according to my Invention, and Figure is a plan thereof. This form of pump is
to be attached to the bottom of the brine receptacle, and actuated by a hand lever
above in like manner as the form of pump before described. In this form of
pump,
and for this application there is but one valve B, which is a ball of glass, as in the
other form of pump. described, though other material may be used. The seating for
this valve is at the lower end of the intérior chamber N of the pump, which is of
conical form, as shewn. Surrounding the lower part of this interior conical chamber
is an outer chamber O, perforated to admit the brine to the valve B, such perforated
chamber acting also as the strainer. Communicating with the inner chamber N is
the outlet D, to which the india-rubber tube E and nozzle F are attached, and the
said inner chamber N is covered at the top by a diaphragm P of cured india-rubber,
leather, or other similar pliable material, but I prefer the india-rubber, as it may be
used without bagging. To this diaphragm P is attached the connecting rod I, and
the operation of the pump is as follows:-As the connecting rod and diaphragm are
raised by the action of the hand lever G, the valve B is raised, and the brine is
drawn into the inner chamber N; and on the connecting rod and diaphragm being
depressed the valve B is forced to its seating, and the brine through the outlet D.
and pipe E and nozzle F. This pump may be used for other purposes than with
my salting machine, and in cases where the valve is not surrounded with liquid, as
described, two valves will generally be found necessary.
I do not confine myself to the precise details described and illustrated.
I claim as my Invention, to be secured to me by the herein-before in part recited
Letters Patent,-
Firstly. The improvements in machinery for salting meat substantially as.

page_text: herein-before set forth and described, and illustrated in the accompanying
Drawings.

hundred and seventy-eight.
