Road, in the Parish of Bermondsey, in the County of Surrey,
Timber Merchant, for the Invention of "IMPROVEMENTS IN THE
CONSTRUCTION OF ENCLOSED SCREENS WITH DUST BINS FOR DOMESTIC AND
OTHER PURPOSES."
Sealed the 25th March 1873, and dated the 28th September 1872.
PROVISIONAL SPECIFICATION left by the said Edward John Cain at
the Office of the Commissioners of Patents, with his Petition, on the
28th September 1872.
I, EDWARD JOHN OAIN, of No. 91, Upper Grange Road, in the Parish
of Bermondsey, in the County of Surrey, Timber Merchant, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE
CONSTRUCTION OF ENCLOSED SCREENS WITH DUST BINS FOR DOMESTIC AND OTHER
PURPOSES," to be as follows:-
-
This Invention consists in the construction of a box in wood, metal, or
any other material, which box contains a screen placed at an angle, so.
that any material placed upon it shall roll off it by its own specific
gravity. Underneath this screen is one or more divisions. forming
.

page_text: receptacles for the material passing through the screen, and at the
lower end of the screen is one or more divisions forming receptacles
for the material passing over the screen, whilst over the screen at
about the highest point from the base line of its adjustment is placed a
hopper, into which the material to be screened is passed, the portions
thereof too large to pass through the screen travel over it, and drop into
the receptacle at the lower end of the screen, and the smaller portions
passing through the screen into the receptacle underneath. This con-
struction forms an enclosed screen with dust or refuse bin applicable
to domestic and other purposes, and which may be portable or fixed.
As the nature of my said Invention is capable of various modifications
without departing from the principle thereof, I do not restrict myself to
material or the precise form or dimensions of the several parts.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward John Cain in the Great Seal Patent Office
on the 28th March 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Edward
JOHN CAIN, of No. 91, Upper Grange Road, in the Parish of Bermondsey,
in the County of Surrey, Timber Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of September, in
the year of our Lord One thousand eight hundred and seventy-two, in
the thirty-sixth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Edward John Cain, Her
special licence that I, the said Edward John Cain, my executors,
administrators, and assigns, or such others as I, the said Edward John
Cain, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF ENCLOSED SCREENS WITH DUST BINS FOR
DOMESTIC AND OTHER PURPOSES," upon the condition (amongst others) that I,
the said Edward John Cain, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and

page_text: seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Edward John Cain, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, that is to say:—
This Invention consists in the construction of a box in wood, metal,
or any other material, which box contains a screen placed at an angle,
so that any material placed upon it shall roll off it by its own specific
gravity. Underneath this screen is one or more divisions forming
receptacles for the material passing through the screen, and at the lower
end of the screen is one or more divisions forming receptacles for the
material passing over the screen, whilst over 'the screen at about the
highest point from the base line of its adjustment is placed a hopper,
into which the material to be screened is passed, the portions thereof too
large to pass through the screen travel over it, and drop into the recep-
tacle at the lower end of the screen, and the smaller portions passing
through the screen into the receptacle underneath. This construction
forms an enclosed screen with dust or refuse bin applicable to domestic
and other purposes, and which may be portable or fixed.
And in order to explain my said Invention more fully I now proceed
to describe the means by which it may be carried into practical effect,
reference being had to the illustrative Sheet of Drawings accompanying
these Presents, and to the numeral figures and letters of reference
marked thereon respectively, as follows:—
DESCRIPTION OF THE DRAWING..
Figure 1 represents a side elevation of my improved screen; Figure 2,
a top plan view of Figure 1 without the lids or covers there shewn ;
Figure 3, a vertical section through the line A, B, at Figure 2. At each
of the above mentioned Figures similar letters of reference are employed
to denote corresponding parts.

page_text: fixed to a rectangular frame of wood E which rests on inclined pieces a
fixed to opposite sides of the box or case A; G, a hopper or opening for
introducing cinders and ashes, for example; H, I, are drawers to receive
the cinders and ashes separately; K is a partition extending across the
entire width of the box or case A for separating the boxes H and I; 5
L are antifriction rollers fixed to the bottoms of the boxes H, I, to
enable them to be moved in and out freely. The operations of the above
mentioned arrangements are as follows:-Suppose cinders are required
to be sifted, the cinders and ashes are placed in the hopper G, the lid C
being first closed. The cinders will pass down the screen D, and fall 1
into the drawer H, and the dust will pass into the drawer I, and in this
manner and by these means cinders and other ingredients, matters, or
substances may be screened or separated from dust and dirt in a simple
and efficient manner.

Having now fully described and set forth the nature and object of my 1
said Invention for "Improvements in the Construction of Enclosed Screens
with Dust Bins for Domestic and other Purposes," and the means by which
may be effected in practice; I would remark in conclusion that I do
not restrict myself to the precise shape of the several parts, nor the
angle at which the screen D is placed; neither do I claim the exclusive 2
use of any of the separate parts above mentioned and referred to, except
in so far as the same may be employed in combination and for the
purposes of my said Invention; and I hereby declare my Invention to
consist in, and I claim, constructing enclosed screens with dust bins
suitable for domestic and other purposes, in the manner above described 2
with reference to the accompanying Drawing.
In witness whereof, I, the said Edward John Cain, have hereunto
set my hand and seal, this Twenty-fourth day of March, in the
year of our Lord One thousand eight hundred and seventy-three.
