Meat, Fruit, and other substances.
FRED SUMMERFIELD The School House, Yorke Street St. Paul's Road,
Southsea, Machinist do hereby declare the nature of this invention to be as
follows:-
A circular cast-iron basin carrying an iron bracket through the top centre of
which passes a steel screw. On the end of this screw there is an iron plunger.
Immediately beneath this plunger is a double cylinder, finely perforated, and
attached to the iron basin by a square stud. The meat, fruit or other substance
the essence of which is required is placed in the cylinder, the plunger is worked
down upon it by means of the screw and the juices are forced out through the
perforated sides into the basin.

Improvements in Apparatus for Extracting Juices or Essences from
Meat, Fruit, and other substances.
I FRED SUMMERFIELD of School House, Yorke Street, St. Paul's Road,
Southsea, Machinist 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 :-
The invention which is designed to obtain, by means of pressure, the juices from
many edible substances, consists of the following apparatus:
A circular cast-iron glazed reservoir with lip for pouring. It carries on its
outer circumference three stops which fit into a stand to be hereafter described.
In the centre of the reservoir, which is three quarters of an inch in depth,
there is a raised circular stand designed to carry a cylinder hereafter described
this circular stand which is four inches in diameter has a triangular bearing with
a square five-eights stop in the centre. The reservoir which is eight inches in
diameter has a capacity for half a pint of liquid. The reservoir is marked A in the
accompanying plan.
Attached to the side of the raised stand in the reservoir, and separated from
each other by the diameter of the stand, are two inch and a quarter lugs into
which are screwed two five-eight turned uprights, each being ten and a quarter
inches in height with a screw at the top. These uprights, which are made of
malleable steel, carry a cross-head of the same metal varying in width from an inch
to an inch and five-eights. This cross-piece is fastened down to the uprights by
two five-eight nuts, and is bedded on two shoulders. The uprights and cross-piece
are marked B in the accompanying plan.
Through the centre of the cross-piece passes a five-eight Whitworth steel screw
ten inches in length, on the top of which is a square head for a wrench. This
wrench which is twelve inches in length, and is made of malleable steel, is turned
up at one end for the carrying of a revolving handle. At the bottom of the screw
there is a plain surface with a groove, the object of which is to permit the plunger
next to be described to be driven down without revolving the screw is marked C,
and the wrench D; on the accompanying plan.
The plunger which is attached to the bottom of the Whitworth screw by means
of two set screws, is made of malleable steel; is three inches in diameter, the
TDQ27

page_text: flange being half an inch in thickness, and the bush for the end of the running
screw an inch in depth. The flange has attached to its under surface a thin flat
layer of india-rubber which is kept in position by a thin steel plate equal in
circumference to the rubber and the flange to which it is fastened by means of
screws. The plunger is marked E upon the plan.
Upon the stand before mentioned and immediately beneath the plunger just
described, a moveable perforated cylinder is placed being kept in position by
means of the square stop on the stand which fits into a hole in the base of the
cylinder. The height of the cylinder is four and a half inches and its outside
diameter three and a half. It is made of wrought-iron and turned. This cylinder
is marked F. on the accompanying plan.
The perforations in the cylinder are three-sixteenths in diameter; but it is
provided with a number of moveable steel insets perforated in varying degrees
down to the finest gauze.
The apparatus is provided with a cast-iron stand designed for resisting pressure
and for allowing the reservoir to be emptied without unshipping the apparatus.
The stand, which is fastened down by three screws, the lugs being inside, carries
three resisting brackets into which the stops on the outside of the reservoir fit.
The stand is circular, save for a segment which has been cut off in front to allow
of the unimpeded tipping of the reservoir, and across this segment there is a band
of iron to strengthen the stand which is marked G. upon the plan.
The object of the apparatus is to extract the juices from meat, either raw or
cooked, vegetables, fruit and other substances, which it does most effectually. The
method of working is as follows:-
Place the apparatus on the stand; into the cylinder put the substance the juice
of which is desired; place the cylinder in position under the plunger and then
work the screw down. Under the great pressure thus obtained all the juice contained
in the substance is pressed out and it flows through the perforations in the cylinder
into the reservoir. No juice can escape upwards above the plunger in consequence
of the action of the india-rubber which is pressed outwards more and more as the
pressure increases. To prevent the dispersion of the juices which sometimes
escape with considerable force a thin moveable metal shield is placed around the
cylinder.
The apparatus can be made in various sizes.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same to be performed, I declare that what I
claim is :-
