WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "AN IMPROVED VENTILATED CASE OR BIN
FOR THE STORAGE AND PRESERVATION OF GRAIN OR SEED." [A communication
from abroad by Eugène Jacques Wilhelm Geelen, of Rotterdam, Holland.]
This Invention relates to an improved portable ventilated case, bin, or apparatus
to be employed for the storage and preservation of grain or seed, which case is
provided with sides or walls of perforated sheet metal or wire gauze, and with a
central flue or passage whose surface is also of perforated sheet metal or wire
gauze.
→
In carrying the said Invention into practice I provide four upright posts or
standards and unite them by horizontal cross-pieces; the lower portion of the
frame thus made is provided with solid panels, in one of which there is an aperture
furnished with a sliding cover or door. The sides of the case or frame are covered
with perforated metal sheets, preferably zinc. Any suitable perforated metal may
be employed, or I may use strong wire gauze. To facilitate the taking apart and
setting up of the case I make use of long screws for uniting the uprights.
The upper part of the said case or apparatus is provided with two hinged covers,
one of which is furnished with a metal cross-bar serving to secure or fasten the
covers. This bar has at one end a long slot which receives a bent piece or hook
provided on one end of a rod which extends to the lower part of the case or
apparatus, where it is provided with a handle, by means of which the rod may be
turned or operated. When this handle is fastened to the case by means of a

page_text: padlock, for which provision is made, the aforesaid piece or hook lies in a position
at right angles to the cross-bar and the covers or lids cannot be opened, but if the
handle is released and turned the bent piece or hook is brought co-incident with
the slot on the cross-bar so that the covers may be opened; the aforesaid sliding
door is also released by turning this handle.
The bottom or lower part of the case is made with three pieces forming inclined
planes, all of which converge towards the opening covered by the sliding door, and
to ensure strength and provide at the same time for separating the parts when
required I arrange the same as follows, that is to say:-The side pieces of the part
forming the bottom of the case are supported by iron bands, which prevent their
separation when the case or apparatus is dismounted or taken apart. I further
unite the three inclined pieces forming the bottom by two solid pieces of wood
nailed underneath. In putting the case or apparatus together when the two
sides and the rear part thereof are in place, the bottom piece is inserted and slides
on two very strong wooden guides, the rear part being supported by a cross-piece
at the end of the case; there are also two supporting pieces in front.
There is a central flue or passage which rests on the bottom of the case and
extends to the top thereof. This flue is constructed of a light framework of laths
or upright pieces united and strengthened by triangular transverse stays, one
placed at the top, another about the centre, and a third at the bottom. This
frame is surrounded by perforated zinc, and I place bands, or pieces around the
zinc at the top and bottom of the flue. Those at the top are slightly below the
internal stay to serve as supports to the covers.
The flue is open both at the top and bottom thereof, but if necessary it may be
covered by wire gauze or perforated sheet metal. The said flue is secured to the
lower part of the case by means of three extensions which pass through the bottom,
the lower triangular band resting on the bottom and being fixed thereto.
The part of the cover or lid attached to the front portion of the case or apparatus,
which part is seldom opened, holds the flue or shaft at the top thereof and retains
it in a perpendicular position.
This improved case or apparatus is very advantageous in use. It is inexpensive,
clean, keeps the contents in good condition, provides perfect ventilation, and
occupies a small space.

by the said William Robert Lake in the Great Seal Patent Office on the
6th November 1880.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "AN IMPROVED VENTILATED CASE OR BIN
FOR THE STORAGE AND PRESERVATION OF GRAIN OR SEED." A communication
from abroad by Eugène Jacques Wilhelm Geelen, of Rotterdam, Holland.
This Invention relates to an improved portable ventilated case, bin, or apparatus
to be employed for the storage and preservation of grain or seed, which case is
provided with sides or walls of perforated sheet metal or wire gauze, and with a
central flue or passage whose surface is also of perforated sheet metal.
The said Invention is illustrated in the accompanying Drawing, in which,-
Figure 1 is a front view.
Figure 2, a. plan.
Figure 3, a vertical section on the line M, N, Figure 2, and
Figure 4, a similar section on the line P, Q, Figure 1, of a case or apparatus
embodying my improvements.
The said case, bin, or apparatus has four upright posts or standards A united by
horizontal cross-pieces B, and the lower portion of the frame thus made is provided
with solid panels C, in one of which there is an aperture furnished with a sliding
cover or door D. The sides or panels of the case or frame are covered with
perforated metal sheets E, preferably made of zinc. Any suitable perforated metal
may however be employed, or I may use strong wire gauze. To facilitate the
taking apart and setting up of the case or apparatus and its transportation, I make
use of long screws for uniting the uprights.
The upper part of the said case or apparatus is provided with two hinged
covers F, F, one of which is furnished with a cross-bar G of iron or other metal
serving to secure or fasten the covers. This bar has at one end a long slot a, which
receives a bent piece or hook b provided on one end of a rod c which extends to the
lower part of the case. This rod or apparatus is provided with a crank or handle d,
by means of which the rod may be turned or operated. When this crank or handle
is placed against the side of the apparatus, and is fastened to the same by means of
a padlock or otherwise, for which provision is made, the aforesaid bent piece or
hook lies in a position at right angles to the cross-bar G, and the covers or lids
cannot then be opened, but if the handle d is released and turned, the bent piece or
hook b is brought in a line with the slot a in the cross bar, so that the covers may
be opened; the aforesaid sliding door D is also released by turning this handle.
The bottom or lower part of the case is formed by three sloping boards M, N, P,
forming inclined planes, all of which converge towards the opening covered by the
sliding door. To ensure strength and to provide at the same time for readily
separating the parts when required, I arrange the same as follows, that is to say :-
The lateral pieces of the part forming the bottom of the case are supported by
iron bands ff, which prevent their separation when the case or apparatus is
dismounted or taken apart. I further unite the three inclined pieces forming the
bottom by two solid pieces of wood nailed underneath the same. In putting the
case or apparatus together when the two sides and the rear part thereof have been
set up, the bottom piece is inserted and slides on two laths or guides e, e, of wood of
sufficient strength, and the rear part is supported by a cross-piece or lath g at the
end of the case. There are also two supporting laths or pieces in front.
Within the said apparatus there is a central flue or passage which rests on the
bottom of the case and extends to the top thereof. This flue is constructed of a
light framework made of three laths or upright pieces h, h, h, united and strengthened

page_text: by triangular transverse stays i, i, i, one placed at the top, another at about the
centre, and the third at the bottom. These uprights h, h, h, are surrounded by
perforated zinc j, and I place bands or pieces k, k, l, outside and around the zinc at
the top and bottom of the flue. Those at the top are slightly below the internal
stay to serve as supports to the covers. .
The flue is open both at the top and bottom thereof, but if necessary the
openings may be covered by wire gauze or perforated sheet metal. The said flue is
secured to the lower part of the case by means of three lower points or extensions
1, 1, 1, which pass through the bottom, the outer triangular band k, k, resting on
the bottom and being fixed thereto.
The part of the cover or lid attached to the front portion of the case or apparatus,
which part is ordinarily kept closed, holds the flue or shaft at the top thereof, and
retains it in a perpendicular position.
This improved case or apparatus, which may be of any size or capacity, is very
advantageous in use. It is inexpensive to construct, ensures cleanliness, keeps the
contents in good condition, provides perfect ventilation, and occupies a small
space.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim,
A ventilated case, bin, or apparatus comprising an interior flue or shaft with
perforated sheet metal walls; also perforated sheet metal or wire gauze side panels,
and a bottom formed with three inclined planes converging towards a door, the
whole being constructed and arranged substantially as above described and as
shewn in the Drawing, for the purpose set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Sixth day of November, in the year of our Lord One
thousand eight hundred and eighty.
WM. ROBT. LAKE. (L.S.)
