Improvements in Plates and Boxes for Oil Presses and the like.
I, HERBERT ALEXANDER, of Water Lane, Leeds, in the County of York, Engineer,
do hereby declare the nature of this invention, (a communication to me from abroad
by Antoine Emile Kiderlen, of Amsterdam, Engineer) to be as follows:-
-
Much difficulty has been experienced in expressing the oil from the centre of
oil cakes, owing to the large amount of consolidated material through which the
said oil has to pass in its passage from the centre of the cake to the outer edge of
same. Difficulty has also been experienced in applying the lining to the interior
of boxes, and as at present made the countersunk rivets form an insufficiently
smooth surface, and cause marks and ridges to be made in the sides of the cakes
on the same being forced out of the box.
According to my invention, I form the plates in compound form, being composed
of a perforated plate, resting on a back or main portion, which latter is provided
with grooves running to the outer edge of the plate. The main portion of the
plate may be formed of a number of parallel bars firmly connected together, or it
may be formed in a corrugated or wave section. The perforated nature of the
upper portion of the compound plate, enables the oil to pass through same and to
be taken off by the grooves on the back portion, thus obviating the necessity of the
oil passing through a large portion of consolidated material in order to escape at the
sides of the cake. The box for containing the cake to be pressed, is divided longi-
tudinally into two parts, and is provided with flanges situated at the divisions for
the purpose of connecting the said halves together by means of bolts or other
clamping devices. The lining which is composed of sheet metal, is bent or other-
wise formed to the shape of the interior of the two halves, overlapping portions
being provided at the places where the box is divided. On the two halves of the
box being placed together with their linings in position, bolts are passed through
the flanges on the box, thus nipping the overlapping portions between the flanges
and keeping the lining firmly in position. It will be readily seen that the attach-
ment of the lining in the manner above described, leaves same with its interior
surface perfectly smooth, which is not the case where rivets are employed.

Improvements in Plates and Boxes for Oil Presses and the like.
I, HERBERT ALEXANDER, of Water Lane, Leeds, in the County of York, Engineer,
do hereby declare the nature of this invention, (a communication to me from abroad
by Antoine Emile Kiderlen, of Amsterdam, Engineer) and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
Much difficulty has been experienced in expressing the oil from the centre of oil
cakes, owing to the large amount of consolidated material through which the said
oil has to pass in its passage from the centre of the cake to the outer edge of same.
Difficulty has also been experienced in applying the lining to the interior of boxes,
and as at present made the countersunk rivets form an insufficiently smooth
surface, and cause marks and ridges to be made on the sides of the cakes on the
same being forced out of the box.
In order that my invention may be clearly understood, I will proceed to describe
same with reference to the accompanying drawings, in which similar letters refer
to like parts in all the figures.
Figure 1 is a plan of a plate shewing my invention applied thereto a portion of
the said plate being broken away for the purpose of clearness, and Figure 2 is a
longitudinal section of the same plate. Figure 3 is a transverse section of similar
plate built up in a modified form, and Figure 4 is a part plan of the same with a
portion of the plate broken away for the purpose of illustrating it clearly.
Figures 5 and 6 are respectively front elevation and sectional plan of a box fitted
with a lining constructed according to my invention.
Referring particularly to Figures 1 and 2, A is a perforated plate having holes B
in same, and C is a back plate which is provided with a number of grooves D
running to the outer edge of the said back plate C, thus leaving projecting parts E.
for supporting the perforated plate A. The perforated nature of the plate A allows
the oil to pass through and be taken off by the grooves D, thus obviating the
necessity of the oil passing through a large portion of consolidated material in order
to escape at the sides of the cake.
In the modified form of plate shewn at Figures 3 and 4, the perforated plate A
is supported on a number of parallel bars F which are carried on a back plate C,
a ring H being employed for the purpose of keeping the bars F in the required
positions. In this form the grooves D are formed by the spaces between the bars F.
Referring particularly to Figures 5 and 6, K is the box for containing the cakes
to be pressed which is divided longitudinally into two parts, and L are flanges
situated at the divisions for the purpose of connecting the said halves together
by means of bolts M. N is the lining which is composed of sheet metal bent or
otherwise formed to the shape of the interior of the box K, overlapping portions P
being provided at the places where the box K is divided. On the two halves being
placed together with their lining N in position, the bolts M are passed through the
flanges L, thus nipping the overlapping portions P firmly together, and securing
the lining in position. It will be readily seen that the attachment of the lining N
in the manner above described, leaves the box K with its interior surface perfectly
smooth.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The plate A having holes B in same in combination with a back plate C

page_text: 2. The plate A having holes Ẻ in same, in combination with the plate C, bars F
and ring H, substantially as and for the purposes set forth.
3. The divided box K having flanges L on same, in combination with the lining N
having overlapping portions P, substantially as and for the purposes set forth."
