Improvements in Cinder Sinters.
1 JAMES STRANAGHAN of 10 Eldon Street, Tatton Street Salford, in the
County of Lancaster, Weighman, do hereby declare the nature of this invention
to be as follows:-
This invention relates to cinder sifters to be placed beneath a fire grate to
separate the cinders from the ashes and dust.
The apparatus consists first of a rectangular box open at the top and having
its front end higher than the back end or otherwise so formed that a loose light
fine grid or sieve can be placed on the open top, and incline downwards from the
front to the back.
The front may be made in the form of an ordinary ash guard front or it may be
made to fit into an ash guard, or ash pan; and I also propose to provide the upper
part of each side of the box with a hinged or adjustable flap or plate so that the
box can thus be made to fit a wider grate if necessary; the front end of each of
these flaps is made to fit the front of the ashguard or ashpan, and fill up any space
between the said front and the box.
The grid or sieve may be cast, woven, netted or otherwise formed so as to
separate the cinders from the ashes and dust, but I prefer to make it in the form
of a cast metal grid with thin straight bars at suitable intervals apart running from
front to back of the box so that as it is also inclined downwards in the same
direction, the cinders can roll down over the back of the box but the ashes and
dust will fall through the grid into the box.
In conjunction with this box I also propose to use a second receptacle or box of
suitable shape to fit in the fire place below the grate and behind the first named
box, but close to the same, so that the cinders can fall over the back end of the
grid into this second receptacle or box.
The loose grid is provided with a projecting pin or pins at the front end fitted
into suitable holes or recesses in, or over the front of, the first box and with a
similar pin or pins at the back similarly fitted to the back end of the first box, or
fitting in recesses in, or over the front side of, the second receptacle or box; or the
two boxes are otherwise so connected together that they can be withdrawn from
the fire place together, a convenient handle or a knob or other device being
provided on the front of the first named box for that purpose; or other equivalent
means can be employed for fixing the grid upon the box or boxes.
The grid is or may be provided with a ring or knob to facilitate its removal
from the box or boxes when it is desired to remove the contents therefrom.
The two boxes may either be placed in the space between the hearth and the
bottom of the grate, or they may if preferred, be sunk in a pit below the fire place
so that the grid or sieve will be level with the hearthstone.
A hinged or other handle or rail is, or may be, fitted to either or both boxes to
enable it to be more readily carried when full; the handle when hinged or
pivotted will, when not required, fall out of the way into the box.
It will be evident that the box or receptacle for the cinders may be dispensed
with, but I prefer to use the entire combination hereinbefore described.
Dated this 24th day of July 1894.

Improvements in Cinder Sifters.
I JAMES STRANAGHAN of 10 Eldon Street, Tatton Street Salford in the
County of Lancaster, Weighman, 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 :—
This invention relates to cinder sifters to be placed beneath a fire grate to
separate the cinders from the ashes and dust; and the said invention will be
readily understood from the following description on reference to the accompanying
sheet of drawings of which Fig. 1 is a longitudinal section of a cinder sifter
constructed according to my invention.
Fig. 2 is a transverse section through about the line A-B on Fig. 1. Fig. 3 is a
plan view of the same.
Fig. 4 and Figs. 5 and 6 shew modified forms of my invention hereafter more
particularly referred to.
The apparatus consists first of a rectangular or other suitable box a open at the
top and having its front end higher than the back end or otherwise so formed that
a light fine grid or sieve can be placed or fixed on the open top and incline
downwards from the front to the back see Fig. 1.
The front a' may be made in the form of an ordinary ash guard front as shewn or
it may be made to fit into an ash guard or ashpan; and I also propose to provide the
upper part of each side of the box with a hinged, flexible, or otherwise adjustable
flap or plate a*, so that the box can thus be made to fit a wider grate if necessary;
the front end of each of these flaps is made to fit close to the front of the ashguard
or ashpan and fill up any space between the said front and the box.
The grid or sieve b may be cast, woven, netted or otherwise formed so as to
separate the cinders from the ashes and dust but I prefer to make it in the form of
a metal grid with thin straight wires or bars at suitable intervals apart running
from front to back of the box, as seen at Fig 3, so that as it is also inclined
downwards in the same direction the cinders can roll down over the back
of the box a but the ashes and dust will fall through the grid b into the
box a.
In conjunction with this box a I also propose to use a second receptacle or
box c of suitable shape to fit in the fire place below the grate and behind the
first named box a but close to the same, so that the cinders can fall over the
back end of the grid & into this second receptacle or box c.
The loose grid b is provided with a projecting pin or pins 6' at the front
end fitted into suitable holes or recesses a in or over the front of the first box,
and if desired with a similar pin or pins at the back, or a flange similarly fitted
to the back end of the first box b, or fitting in recesses in or over the front
side of the second receptacle or box c, or the two boxes are otherwise so con-
nected together that they can be withdrawn from the fire place together.
convenient handle or a knob c' or other device is provided on the front of the
first named box for that purpose; and other equivalent means can be employed
for fixing the grid upon the box or boxes.
A
I sometimes also bend over the edge of one of the boxes so that it covers the
joint between them and helps to connect them, and prevents ashes from falling
between the boxes, as seen by Figs. 1, 4 and 5.
The grid if loose is or may be provided with a ring or knob to facilitate
its removal from the box or boxes when it is desired to remove the contents
therefrom.
The two boxes may either be placed in the space between the hearth and the
bottom of the grate, or they may, if preferred, be sunk in a pit below the fire
place.

page_text: A hinged or other handle or rail a³, c³ is or may be fitted to either or both boxes
to enable it to be more readily carried when full, the handle when hinged or
pivotted will, when not required, fall out of the way into the box, as shewn on
Fig. 1.
It will be evident that the box or receptacle c for the cinders may be dispensed
with, but I prefer to use the entire combination hereinbefore described.
The shape of the sifters will vary according to the grates to which they are to
be applied.
In cases where the ashpit does not extend behind the fire grate we put the box c
in front of the box a, and in that case the ashguard preferably forms part of the
box cas seen at Fig. 4, and Figs. 5 and 6, which show respectively two
modifications of my invention adaptable to different forms of fire grate.
On Fig. 4 the ash guard c is shewn hinged to the back of the box c so that it
can be set in the position shown, or horizontally if it is desired to place anything
thereon in front of the fire.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. The combination with a box or receptacle for ashes having an inclined
open top provided with an inclined grid, with a second box or receptacle for
cinders, substantially as hereinbefore described and illustrated by the annexed
drawings.
2. A box or receptacle for ashes having an ash guard at the front and an
inclined open top, and provided with an inclined grid covering the said open top,
and with or without adjustable flaps at the sides substantially as described with
reference to Figs. 1, 2 and 3 of the annexed drawings.
Dated this 6th day of October 1894.
