A Cinder Sifter and Dustbin Combined.
I, EDWARD ALFRED ATTWOOD of 16 Shipka Road, Balham in the County of Surrey,
Gentleman, 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 my present invention is an apparatus combined with a dustbin for
sifting cinders which is suitable for domestic use or for use in large establishments
or institutions.
The devices at present in use for the purpose possess various disadvantages to
obviate which I have designed an apparatus which will efficiently and quickly separate
the cinders from the ashes without producing dust or waste and which is capable of
being used by the most unskilled person.
The invention is illustrated in the accompanying drawings in which Fig. 1 is a
vertical cross section of my combined dustbin and cinder sifter showing the latter in
position for sifting and Fig. 2 is a like view showing the sifter and its lid in position
to discharge the cinders into a suitable scoop or receiver and Fig. 3 is a like view to
Fig. 1 showing a slight modification.
The apparatus may be constructed in various forms and sizes according to the class,
of material of which it is made and the amount of work to be done. It can also be
constructed to fit on the top of existing dustbins but for general domestic use I prefer
to construct it of iron or wood in the form of a box a either square or round or of
other shape provided with a riddle or sieve 6 let into the lid a¹ and secured by hinges c
to the upper edge of a hopper a² formed around the opening in the lid a¹.
I also provide the riddle or sieve b with a handle b¹ on the side opposite to that of
the hinge c to enable it to be lightly jerked up and down to cause the ashes to drop
through into the box a below and to retain the cinders in the riddle or sieve.
The riddle or sieve b is also fitted with a lid 62 also hinged at c so that the lid can
be placed on the top of the hopper a² over the riddle or sieve for sifting to prevent
escape of dust and be turned over and form a shoot, for the cinders to run down the
same into a coal scuttle or other receiver placed by the side of the box a to receive
them, when the sieve is raised by the handle b¹, out of the box and turned over to
discharge the cinders.
In-the modification represented at Fig. 3 the side of the hopper a² opposite to that
of the hinge c is somewhat higher than the latter in order that a longer stroke may
be given to the sieve when sifting.
The sieve or riddle has its sides as well as its bottom formed of or fitted with
perforated or reticulate material.
When it is desired to use the apparatus the lid 62 of the riddle or sieve b is raised and
the ashes and cinders placed in the latter, the lid is then closed and a few jerks
upward and downward given to the riddle or sieve will cause the ashes to fall through
into the box a below.
The riddle or sieve b and its lid 62 are then turned on the hinges c as shown in
Fig. 2 when the lid will rest on the edge of the dust bin lid and form a shoot down

which the cinders discharged from the riddle or sieve will run into any suitable
receiver.
The lid a¹ is removed from the dust bin when it is desired to discharge the ashes
from the latter.
By these means the separation of the cinders from the ashes is effected much more
quickly than heretofore and without creating so much dust and dirt as is usually the
case at present.
I would remark that the apparatus may be made of various forms and materials
and the riddle or sieve may be provided with other means to actuate the same whilst
if desired a dust bin may be provided with more than one of such cinder sifters.
I have shown the hopper with vertical sides but it will be understood that it may
be made with inclined or other sides.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The combined cinder sifter and dust bin substantially as herein set forth.
2. The combination with a dust bin of a hopper rising from the lid, a riddle or
sieve and its lid hinged to one side of said hopper, said lid being also employed as a
shoot down which the cinders are discharged and means whereby the sieve can be
manipulated substantially as herein set forth.
