PROVISIONAL SPECIFICATION.
Improvements in and relating to Riddles or Sieves.
I, GEORGE COTTON of Middlewich, Cheshire, Draper, do hereby declare the nature.
of my said invention to be as follows:-
The object of my invention is to construct a loose riddle or automatic cinder sifter
of suitable shape so as to fit into the mouth and partake of the configuration of the
upper part of a coal scoop, scuttle, house bucket or other similar receptacle. In this
manner and by simply introducing the cinders I am enabled to sift the same in a neat
and cleanly manner and to allow the dust to fall into the lower part of the receptacle
this operation taking place in the same apartment as the fire place and without
the necessity of removing the cinders to another part of the premises as heretofore
thus saving considerable time and labour. As applied to a coal scoop or scuttle the
shape of this riddle facilitates the pouring out of the contents say cinders on to a
fire place.
For the better class of cinder sifters I cover the top of the riddle casing either
partially or entirely with a cover and in this case the riddle portion may be formed
as a false bottom and so capable of being lifted and shaken independently by a rod
passing through the cover.
These improvements are equally applicable to ordinary riddles or riddles employed
for agricultural purposes say for instance in riddles for sorting potatoes, grain or
other edibles the shape of the casing facilitating the pouring of the contents into
sacks or other receptacles.

COMPLETE SPECIFICATION.
Improvements in and relating to Riddles or Sieves.
I GEORGE COTTON of Middlewich Cheshire Draper 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 :-
The object of my invention is to construct a loose riddle or automatic cinder
sifter applicable to the upper part of a coal scoop, coal scuttle or other similar
receptacle as hereinafter described and illustrated on the accompanying drawing.
Fig. 1. represents a side and front sectional view of an ordinary coal box or scuttle
with the simplest form of my improved riddle applied.
a is my improved cinder sifter or riddle shewn raised out of the receptacle b to
illustrate that it fits into the mouth and partakes of the configuration of the upper
part of such receptacle. The sifter a is constructed of sheet metal wood or other
suitable material and of a suitable depth to receive the cinders and with a wire work
grating or bottom c.
Being placed in position in the coal box b by simply introducing the cinders and
ashes into the riddle a I am enabled to sift the same in a neat and cleanly manner
and to allow the dust to fall into the lower part of the receptacle 6 this operation
taking place in the same apartment as the fire place and without the necessity of
removing the cinders to another part of the premises as heretofore thus saving
considerable time and labour. As thus applied to a coal scoop or scuttle it will be
obvious that the shape of this riddle or sifter a facilitates the pouring out of the
contents say cinders on to a fire or into any receptacle.

page_text: For the better class of cinder sifters I cover the top of the riddle casing with a
cover d as illustrated in sectional views Fig. 2.-the end e or other part of this cover
being hinged and arranged to open as indicated by dotted lines for the introduction
of the cinders and other fire refuse and either to use with a shovel or ash pan-the
size of opening varying accordingly.
In Fig. 3. I illustrate a similar arrangement to that in Fig. 2. but in this case the
riddle portion a is formed with a loose or false bottom c (constructed of wire work)
and so capable of being lifted and shaken independently by a rod f passing through
the cover to effect the sifting operation.
In sectional views Fig. 4. I represent another modification of my invention in
which the cover g is formed in one piece with or permanently secured to receptacle b
hinged in the middle as illustrated and instead of the riddle or grating c being
affixed to the bottom of the casing of the cover as in Fig. 2. it is formed upon a
separate casing (as indicated partly removed by dotted lines) and hence is capable
of removal through the hinged cover i.
In my provisional specification I mentioned my improvements as applicable to
household buckets but I have since learned that a combined cinder sifter and bucket
had been introduced into the market and hence I disclaim this part of my
application.
Having thus particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1st. The improvements in riddles applicable also to coal scoops and other similar
articles substantially as hereinbefore described and illustrated on the accompanying
drawing.
2nd. The combination and arrangement of cinder sifters and coal scoops and with
or without covers substantially as hereinbefore described and illustrated on the
accompanying drawing.
