Year: 1877

page_text: LETTERS PATENT to Thomas McDonald, Oil Mill Foreman, and Joe William
Lawrence, Millwright, both of Hull, in the County of York, for the Invention
of "IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN THE Manu-
FACTURE OF OIL SEED AND COMPOSITION CAKES."
PROVISIONAL SPECIFICATION left by the said Thomas McDonald and Joe
William Lawrence at the Office of the Commissioners of Patents on the oth
December 1877.
THOMAS MCDONALD, Oil Mill Foreman, and JOE WILLIAM LAWRENCE, Millwright,
both of Hull, in the County of York. "IMPROVEMENTS IN MACHINERY OR
APPARATUS EMPLOYED IN THE MANUFACTURE OF OIL SEED AND COMPOSITION
CAKES."
This Invention relates to improved appliances for measuring and preparing the
quantity of seeds or composition from which a "cake" is to be made; also to
improved appliances for the reception of the seeds or composition (so measured and
prepared) in the oil or finishing press.
The "kettle" or hopper containing the seeds or composition is mounted upon a
supporting frame having a passage or exit way for contents of the kettle or hopper.
Under the supporting frame is a hinged and counterbalanced measuring box similar
in action to a printer's " tympanum," and a platform or damper which shuts off the
supply from the kettle or hopper. The measuring box and damper are carried upon
a sliding platform; there is also a bed piece, false bottom plate for measuring box,
and folding rods for purposes herein-after referred to.
The action of the apparatus is as follows:-The plate or false bottom of the
measuring box is placed upon the bed piece, and covered by a cloth. The measuring
box is lowered upon the cloth and bed piece, and the platform slided" to and fro
under the kettle or hopper whereon the box is accurately filled; the edge of the
hopper support acts as a strickle, and the damper platform shuts off supply. The
box is raised and the folding rods moved or brought together upon their hinges or
D31

page_text: centres folding the cloth over the seeds or composition which are then in the cloth,
and upon the plate or false bottom removed to another machine to be partly com-
pressed preparitory to the finishing operation performed in the main or oil press.
In the main or finishing (oil) press, in lieu of the ordinary envelopes or wrappers
we employ a receptacle for the seeds or composition, consisting of a frame (of
required shape of cake) having a longitudinal movable division plate corrugated on
both sides or faces Within this frame seeds or composition are (when previously
prepared) placed on each side or face of the division plate, so that two cakes will
be made in each of such frames.
SPECIFICATION in pursuance of the conditions of the Lotters Patent filed by
the said Thomas McDonald and Joo William Lawrence in the Great Seal Patent
Office on the 6th June 1878.

The "kettle or hopper containing the seeds or composition is mounted upon a
supporting frame, having a passage or exit way for contents of the kettle or hopper
Under the supporting frame is a hinged and counterbalanced measuring box similar
in action to a printer's " tympanum," and a platform or damper, which shuts off the
supply from the kettle or hopper. The measuring box and damper are carried
upon a sliding platform; there is also a bed piece, false bottom plate for measuring
box.
"
The action of the apparatus is as follows:-The plate or false bottom of the
measuring box is placed upon the bed piece, and covered by a cloth. The measuring
box is lowered upon the cloth and bed piece, and the platform slided" to and fro
under the kettle or hopper whereon the box is accurately filled; the edge of the
hopper, kettle, or trough support acts as a strickle, and the damper that form sheets
of supply. The box is raised, and the cloth is folded over the seeds or composition
which are then in the cloth, and upon the plate or false bottom removed to another
machine to be partly compressed preparatory to the finishing operation performed in
the main or oil press.
In the main or finishing (oil) press, in lieu of the ordinary envelopes or wrappers,
we employ a receptacle for the seeds or composition, consisting of a frame or box
(of required shape of cake) having a longitudinal moveable division plate corrugated
on both sides or faces. Within this frame seeds or composition are (when previously

page_text: prepared) placed on each side or face of the division plate, so that two cakes will be
made in each of such frames.
The nature and particulars of this our Invention will be clearly understood on
reference to the accompanying description, aided by the Drawings annexed, of
which Fig. 1 is an elevation of measuring box, kettle and parts connected therewith;
Fig. 2 is a longitudinal vertical section of the same; Fig. 3 is a plan view.
At Figs. 4, 5, and 6, is shewn the frame and division plate for moulding two
cakes.
At A is the kettle, or hopper (containing the seed or composition carried by sup-
porting frame. The exit way for seed from the kettle A may be by way of the
spout B, or through an aperture formed through the bottom of the kettle; C is the
hinged measury box, counterbalanced by weights D, the movement of the said
box being similar to a printer's tympanum. At E is the platform or damper, which
shuts off the seod when the measuring box C is not under aperture; the measuring
box C and damper E are carried by the wheels G upon the platform H. J is a bed
plate, on which the false bottom plate K is placed. Soon as the plate K is in
position, and on being covered by a cloth or wrapper, the counterbalanced measuring
box and its carriage is run under the kettle A, the seed or composition flowing
therefrom fills the measuring box (after the manner of clay filling the moulds of a
brick making machine), and when the latter is drawn from under the kettle the
dampor platform E seals the exit way from the kettle. The measuring box C is
raised, as shewn by dotted lines, Fig. 1, and the other portion of the cloth or
wrapper is folded over the top of the seed in order that the measured sced or com-
position may be removed on the plate K to another machine to be pressed.
In the main or finishing (oil) press, in lieu of the ordinary envelopes or wrappers,
we employ a receptacle for the seeds or composition, consisting of a frame or box L
(of required shape of cake) having a longitudinal moveable division plate M cor-
rugated on both sides or faces. Within this frame seeds or composition are (when
previously prepared) in bags or cloths are placed one on each side or face of the
division plate M, so that two cakes will be made in each of such frames or boxes.
The plate M may be attached to the box, as shewn at Fig. 4, or it may be
unattached, but being in all cases interposed between two bags of seed or compo-
sition to be pressed.
Having thus fully described the nature and object of this our said Invention,
together with the manner in which the same is to be or may be performed or carried
into practical effect, we would have it understood that what we claim as our Inven-
tion is,―
The use and employment of the counterbalanced hinged measuring box C, and for
the purposo as described and illustrated.
We claim the use of the corrugated divisional plate M, as and for the purpose
above described and illustrated.
In witness whereof, I, the said Joe William Lawrence, have for and on behalf
of myself and tho said Thomas McDonald, hereunto set my hand and seal, this
Twenty-seventh day of May, in the year of our Lord One thousand eight
hundred and seventy-eight.
