Composite Cylinders for Presses.
I, ALBRO JARED MORSE, a citizen of the United States, residing in the City of
Harborton and State of Virginia, U.S.A., Engineer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:
i
This invention relates to a novel construction of casing for presses designed
for expressing juices, water, or oil as the case may be, from any desired material.
The object of the invention is to provide a press casing of composite construction
as hereinafter described.
One form of the invention is illustrated in the drawing in which,
Figure 1, is an elevation of the press casing, showing part of it in longitudinal
section, and exposing the three shells of which it is composed.
Figure 2, is a cross section of same.
Figure 3, is a perspective view of a portion of one form of the exterior shell.
Figure 4, is a perspective view of a portion of the interior or lining shell.
Figure 5, is a section on a large scale of a portion of the interior shell, showing
the slot with end beveled away from the woven wire.
My invention is preferably circular in cross section; it may be cylindric in
some cases, or it may be tapered as shown in the present instance.
Essentially the casing is composed of an exterior perforated shell, thick enough
to give the strength required, an interior perforated shell or lining, and a woven
wire shell interposed tightly between the other two shells, the whole forming
a compact composite casing.
Referring now to the drawing, the letter, A, designates the exterior tapered
shell, which in this instance consists of longitudinal tapered bars or slats, b, with
open slits or spaces c, between them. I prefer when making a tapered exterior
shell of slats to employ straight slats, b, and tapered bars, b¹, arranging several,
say three or four, straight slats parallel with each other, and then placing one
tapered bar, &, in position, as shown in Figures 1 and 3. These slats and bars
are exteriorly held in position by bands or hoops, d. Thus constructed the
exterior shell may be made heavy enough to have the required strength to with-
stand the pressure to which the press may be subjected.
It will be understood the exterior shell of the composite press-case may be
made of metal-plate perforated instead of slotted.
Within the exterior perforated shell, A, is a woven wire shell, c, which is in
close contact with and fits the inner surface of said exterior shell.
A thin per-
forated shell F, form the lining and is in close contact with the woven wire shell.
The other shells fits closely together, one within the other, and together make a
composite case. The interior or lining shell, F, is preferably of emooth surfaced
sheet metal, having short slots, g, extending lengthwise and arranged in lines
and so placed that the slots of one line will have position coincident with the
spaces between the slots of the next adjoining lines on either side, in other words,
so that the slots of the several lines will "break joint" as it were. A special
feature of importance in these slots that each slot has a terminal end that

page_text: inclines or bevels inwards as at, gl, that is the bevel or incline is in the direction
from the woven wire toward the interior of the case whereby the material that
is being pressed, passing through the case toward its end, will move along over
the slot and slide up the said bevel or incline, g¹, and not lodge or choke in the
slot. This construction also avoids friction by the passage of the material.
At the large end of the composite press is a receiving chamber, A¹, on which
a funnel or feed hopper, h, is fixed; this chamber may be entirely free from per-
forations or outlets.
To cooperate with the tapered form of case, an internal tapered compressing
screw, s, is employed. This screw is mounted on a shaft, t, extending longi-
tudinally of the case. So far as the composite feature of the case is concerned,
this shaft may be either soild or tubular. If made tubular, the shaft would have
holes along its length fo admit oil, juices or water as shown in Letters Patent
granted to Josephus F. Bussells & A. J. Morse, No. 18379, dated 26 August, 1898.
It is obvious also that my arrangement of three shells as applied to the composite
case, may be applied to the tubular shaft.
the case.
However the shaft may be constructed at the feeding-in or entrance end of
It will turn in a hole, v, in the head which closes the receiving cham-
ber and in a bearing, ¹, at the discharge end.
The shaft, t, projects from one end of the case and may project from both ends,
and on the projecting end a drive wheel, 7, by which revoluble motion may be
imparted to it.
In the operation of a press having a case of this improved construction, each
revolution of the tapered compressing screw, s, forces forward the matter that is
being pressed into a smaller part of the case and there compacts it and expresses
the juices, water or oil, as the case may be, contained in said matter. The con-
struction of the composite case reduces the friction in the case on the inner lining
caused by the matter being forced forward, and the woven wire strains the liquids
without loss of the solid matter.
This invention may be used for pressing any matter from which it is desired
to extract the liquid components. It may be used in connection with the
apparatus patented to Bussells & Morse and already referred to, in which case it
would be a substitute for the compressor case shown in said patent.
Having thus described my invention what I claim as new and desire to secure
by Letters Patent is:―
1. A composite casing for presses designed for expressing any kind of liquid
from matter, comprising an exterior perforated shell, a smooth-surfaced interior
peforated shell, and a woven-wire shell interposed tightly between the other two
shells.
2. A. composite casing for presses comprising an exterior perforated shell, a
woven-shell within said exterior shell and fitting in close contact with the exterior
surface thereof, and a third or inner shell of metal in close contact with the said
woven-wire shell and provided with holes or slots having ends that are inclined
or beveled in a direction from the woven-wire.
3. A composite casing for presses comprising an exterior tapered shell having
longitudinal slats or bars with open spaces or slits between them, a woven-wire
shell resting in the interior of said slats or bars, and a perforated inner lining
or shell in close contact with said woven-wire.
