THOMAS FENN 10 Brasenose Road Kirkdale Liverpool Foreman of Oil and
Chemical Works do hereby declare the nature of the above invention for AN
AUTOMATIC MACHINE FOR PARING LINSEED COTTON AND OTHER CAKES to be as
follows:-
This machine standing on legs, has a horizontal top in the shape of a T. The
cake is laid horizontally on the machine, & drawn by a chain creeper between two
knives which pare parallel sides. It is then deposited on a frame, where a creeper,
travelling at right angles to the first, draws it between two other knives similarly
fixed, which pare the ends. The rests which carry the knives are made to slide, so
that the cake may be pared to the required size.
The machine is driven by a belt with fast & loose pulleys.

page_text: I, THOMAS FENN of 10, Brasenose Road Kirkdale, Liverpool, Foreman of oil and
chemical works do hereby declare the nature of my said invention for "AN AUTOMATIC
MACHINE FOR PARING LINSEED, COTTON, AND OTHER CAKES," and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
This invention has for its object the cutting or trimming of the jagged edges of
oil cakes as they are delivered from the press. The cakes are trimmed by being
laid horizontally on a bed slide or gantree and drawn between two knives which
trim their ends. They are then drawn in the same horizontal plane, but at right
angles to their former travel between two or more knives which trim their ends.
The machine is best explained by aid of the accompanying drawings, in which
Figure 1 is an isometrical view of machine, and Figure 2 a vertical elevation of the
fence H and actuating mechanism as designed for parallel cakes, but I will describe
further on how the same apparatus can be slightly modified so as to to cut taper
cakes also.
A A is the frame work of the machine, made of wood, metal or other suitable
material. B B two parallel bars upon which the cake is laid. B' B¹ side fences or
guides for cake. Cendless belt or chain creeper passing over pulleys F F at each
end strained tight and carrying the abutment D fixed thereto. This abutment is
preferably hooked or hangs forward at about an angle of seventy degrees as shown,
and stands above the surface of bars B, while the belt lies below them. E E¹ mitre
gear driving the shaft F¹. G adjustable stationary knives between which the cake
is forced by abutment D when said cake is placed in front of the latter, when in
the position shown in the drawings. Only one of these knives G is depicted, the
slide or bed upon which the knife is clamped or bolted when in right position, but
in which it is free to slide when not so bolted, being shown at G₁ instead of the
knife. If it be desired to cut taper cakes, in place of a stationary knife, a knife
pressed forward by a spring, but guided by a tem plate on the belt C is used instead.
The knife in such case has a stem or runner abutting against the tem-plate on C.
The stem follows the template, and so cuts the cake to the contour of the tem plate
as in an ordinary copying machine. H (see also Figure 2) are two fingers or other
fence at the end of a rocking lever I pivotted at its end, and connected by link
to lever 12, which latter curving, stands up above the level of bars B and in the
path of the cake, but to one side of the path of the abutment. So long as there is
no cake therefore on the machine, the lever H remains free, but the moment the
cake is put on, it is brought against the lever, and sends the fence into the position
shown in dots. The cake passes on, and the fence strikes the guard raising it in
time to prevent the cake from springing back from fence J which stops its onward
course. Other arrangements for working these fingers can be adopted. An inclined
plane ending with a sudden fall might even be used, or one held up by a weak
spring that the weight of the cake will depress. Arriving between H and J, the
cake falls on the cross bar K, and here a similar mechanism to that described
already is used to shear the ends, for the cake is propelled along by abutment L
travelling on the bands M' M. It is kept in place by fences H and J, and is pressed
between knives R R one of which R is shown, but the other is omitted to show the
bed R¹ upon which it is bolted. There can be two or more pairs of these knives if

page_text: desirable, so that each shall have its share of the work. The finished cake falls off
at N. The bands M M travel tightly over pulleys N N on axis O upon which is
the driving pulley P and the mitre wheel E. The cuttings fall down below
(where, not shown in the drawing) there is a collecting hopper, and an archimedean
conveyor like those used under bolting reels and other milling machinery, or a
travelling band. Or the cuttings can run down inclined planes to the floor outside
of the frame, and be shovelled away at intervals.
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 :-
1st. The manufacture and use of automatic machines for paring linseed, cotton
seed, and other like cakes, in which the cake is passed between two knives or cutters
in one direction, and then caused to travel at right angles to its previous travel, and
pass between two or more other cutters or knives, cutting the two other sides or
ends.
2nd. The mechanism for guiding and passing the cakes against and between the
knives, substantially as described and illustrated.
