I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
'
The object of this invention is to provide a machine which will deprive substances
of any moisture or liquid leaving it in a dry state for future use.
As is well known there are many substances such as brewers grain which are sɔ
charged with liquid that they ferment and become spoiled, yet if that liquid be removed
such waste product becomes of great value. Many methods and apparatus have been
devised to accomplish this result without approaching any certain success.
Heretofore the apparatus for accomplishing this result has been either such as to
produce it entirely by the exertion of pressure or use of heat alone, and if heat and
pressure were combined, the heat was that produced by steami entering the mass itself,
which is the use of moist heat. The object of my improved mechanism is to produce
the desiccation by the use of pressure upon, and a dry heat throughout the mass.
In the accompanying drawings,
Figure 1 represents a view of the entire apparatus with a portion of the outer
cylinder and a portion of the inner perforated cylinder removed.
Figure 2 represents a plan view of the receptacles in which the material to be
desiccated is placed.
Figure 3 represents a view of double discs with supports and divisions.
Figure 4 represents the supports and divisions between the upper and lower surfaces
of the receptacles, shown in Figure 3.

for causing compression.
Figure 7 represents a plan view of the top of the entire apparatus, showing the
gearing for operating the compressing mechanism and withdrawing the receptacles
from the cylinders.
Figure 8 represents a section of the screws and cross beam shown in Figure 1, left-
hand side.
Figure 9 is a detail view of the steam pipe, showing the means for removing the
condensed steam.
A, A, A, Figure 5, are a series of perforated discs joined together in pairs a and b,
Figure 3 by means of the supports and divisions X. These discs are shown in plan
view Figure 2, and have orifices in them through which the upright supports or
guides B pass Figure 5 and upon which supports or guides these receptacles are
strung.
The material to be desiccated is placed upon these discs one at a time adding disc
after disc, until, if desired, discs are used sufficient to cause a height equal to the
capacity of the shell E when the discs are lowered by mechanism to be hereinafter
described into the cylindrical shell E. Within this shell E is a perforated cylindrical
shell D, and between this inner and outer shell are a series of vertical channels M, M,
for the purpose of carrying off the liquid. A series of pipes C, project upward in the
interior of the apparatus through the perforated discs. These pipes terminate at their
lower ends in the steam chamber J Figure 1. The steam or hot air enters this chamber
through the orifice I and travels up through the pipes (, heating the material to be
desiccated with a dry heat throughout. If steam be the heating agent used, I construct
the pipe C, as shown in Figure 9, where within the tube C is a smaller tube c extending
to the desired height, and open at the top. The condensed steam falls into this small
tube, and returning through it falls into the condensing steam chamber j, from which
it is drawn off by the cock K.A removable cover Frests on the top of the cylinder E and
through which the screws H, H', pass at the end of these screws in the piston G, which
rests up in the uppermost receptacles A, the guide B passes also through this piston G.
The guide is locked with the lowermost receptacle by a pin g, passed through an orifice
in theguide B. The guide B may also be connected with the piston G by the pins p,
placed in orifices in the guide B, by which means, when the piston is elevated,
as will hereafter be described, the receptacles are carried up with it out of the
cylinder.
The receptacles being in the cylinder as hereinbefore described the piston G is
caused to be forced upon the receptacles, compressing the discs and the material on
them and depriving the material of its liquid. The piston is operated by means of the
bevel gear h, h¹, and spur wheels h², h³, thereby forcing the piston down and compress-
ing the material to be desiccated, and the liquid is forced up and down and falls
between the upper and lower surfaces of the discs, whence it is carried by the
vertical channels M, M, shown in figure 6, and figure 1, formed upon the inner
periphery of the outer casing E of the apparatus and runs out by the spout N,
Figure 5. When the bevel gear heretofore described is not of sufficient power to
cause the required amount of compression, I add the worm gearing 0, 0,
shown in Figure 1, operated by the wheel o. A beam P connects these two
worm gearings and through this beam the screws H, H¹ pass, and fit so as to
travel up without lifting the beam.
The hubs Z, Z', of the worm gearing O pass through the respective outer ends of
this beam and it is internally threaded, through which the screws y, y¹, pass as
shown in Figures 7 and 8, and when the worm gearing is operated, the heam is
elevated or depressed, carrying with it the screws H, H', and the piston G, and
thereby a more powerful compression may be obtained.
When the compression has been carried on to the extent, aided by the heat,
necessary to deprive the material entirely of its liquid, the bevel gear is reversed
and the screws H, H¹, elevated, carrying with them the plunger G, if, as has been

page_text: heretofore described, the guide B be connected with the piston G, then the receptacles
are drawn out of the cylinders E and the desiccated material may be readily removed,
the cover F having been removed prior to the elevation of the piston.
I do not intend to limit myself to the form of double disc receptacles described as if
desired a series of single discs may be used.
