I, JOHN GARRETT of 97 Barmston Street, Kingston upon Hull, in the County of York,
Shipwright and Joiner, do hereby declare the nature of my invention for "IMPROVE-
MENTS IN WRAPPERS OR APPARATUS FOR MAKING OIL CAKES to be as follows:-
This invention relates to improvements in wrappers or apparatus to be employed in
the making of "cakes" from oil seeds and other like fatty substances, and is designed
to dispense with the "bags "heretofore employed and to expedite the operations of
crushing" and manufacture of such cakes generally.
Apparatus for purpose aforesaid according to this my invention comprises a
corrugated plate mounted in side frames attached to the under side of each of the plates
of the press, the corrugated plate is free to slide a short distance for purposes herein-
after described.
Between the corrugated plate and its frame is a space which forms a groove. The
corresponding half of the wrapper which is detachable from the press consists of a
corrugated plate of metal having a wood or other foundation enclosed in an iron frame
or backing, and at each of its ends are cross pieces, having uprights through which
screws or bolts are passed and support the sides of the wrapper; the sides consist of
upright or angle irons, the screws or bolts admit of the sides being moved outwards
for purpose hereinafter explained.
The operation is as follows
The oil seed or other matter is placed in the detached half wrapper just described,
whereon it is then slided into the press, its upright sides are recessed in the grooves
formed between the upper half of the wrapper and its framing, the grooves hold the

page_text: said upright sides close and firmly to the bottom half of the wrapper when slided into
the press, and the pressure has been applied, the oil is extracted and the cake formed.
Soon as the pressure is taken off, a handle attached to the lower and detachable half
of the wrapper is pulled, whereon the upper corrugated half of the wrapper will slide a
short distance on a slot and holding screw, the under half likewise moving forward,
and by reason of the halves being taper, the lower half is then free to drop loose from
the upper half, and is removed from the press to a table whereon its sides are next
expanded or turned outwards on their studs, and so as to release the edges of the cake
which is then free to be removed from the plate.

page_text: Fig. 1 shews a plan of my wrapper or apparatus for making oil cakes and the like.
Fig. 2 shews an elevation of Fig. 1.
Fig. 3 is an end view of Figs. I and 2.
Fig. 4 is a plan of top half of wrapper or corrugated plate.
Fig. 5 shews plan of bottom half of wrapper with the adjustable sides.
Figs. 6 and 7 are plans of bottom half of wrappers shewing modified adjustable sides.
Apparatus for purpose aforesaid; according to this my invention, the upper half of
the wrapper comprises a corrugated plate A (mounted in side frames B B) attached to
the undersides of each of the plates of the press; the corrugated plate A is free to slide
backwards or forwards a short distance by being attached to the press by means of
studs CD, and plates E, F, with slots or holes G.
Between the corrugated plate A and the side frames B, is a space which forms a
groove H. The corresponding half of the wrapper which is detachable from the press,
consists of a corrugated plate J of metal, having a wood or other foundation K,
enclosed in an iron frame or backing L, and at each of its ends are cross pieces
or uprights M, through which screws, bolts or rivets N are passed, and support the
loose sides P, of the wrapper; these sides consist of upright sides P or angle irons, the
screws, bolts, or rivets, are made so as to admit of the sides P, being moved outwards,
for purpose hereinafter described.
The operation is as follows: The oil seed or other matter is placed in the detached
or lower half of the wrapper, which is then placed in the press, when pressure is
applied the upright sides are pushed into the grooves H formed between the upper
half of the wrapper A and its framing B, the grooves hold the said upright sides close
and firmly to the bottoin half of the wrapper when in the press, and when the pressure
has been fully applied the oil is extracted and the cake formed without the use of bags
as heretofore.
As soon as the pressure is taken off, the handle R attached to the lower and detachable
half of the wrapper is pulled forwards whereon the upper corrugated half of the wrapper
will also slide a short distance forwards on the slots, studs, and plates, and by reason

page_text: of the halves being taper, the lower half is then free to drop loose from the upper half,
and is removed from the press to a table whereon its sides are next expanded or turned
outwards on their studs, so as to release the edges of the cake which is then free to
be removed from the plate.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is :-
1. The use and employment of apparatus for making oblong oil cakes, corn cakes,
and the like, so as to dispense with the use of bags, substantially as and for the purposes
shewn and described.
2. The use of wrappers in halves, one half being attached to the press, and the other
half detached substantially as and for the purposes shewn and described.
3. Constructing one half of the wrapper with adjustable relieving sides substantially
as and for the purposes shewn and described.
4. The general arrangement and construction of the wrappers substantially as and
for the purposes shown and described.
