of the Commissioners of Patents, with his Petition, on the 7th
January 1873.
I, WILLIAM ANYON, Yarn Agent, of No. 82, Waterloo Road,
Manchester, do hereby declare the nature of the said Invention for
" IMPROVEMENTS IN CONSTRUCTION AND FIXING OF FIRE-GRATES FOR DOMESTIC
AND HEATING PURPOSES IN DWELLING HOUSES," to be as follows:-
:-
Fire-grates as at present constructed in dwelling houses are for the
most part composed of fixed or rigid bars, which in front run laterally
from side to side of the fire-place, and which front bars are sufficiently
wide apart to allow of cinders or unconsumed fuel of considerable size to
fall through, thereby causing a large amount of waste in available fuel.
Also from the fixed and rigid construction of sucli grates the fire cannot
be roused or broken up except by the use of a poker or other analogous
means, which often drive out large pieces of unconsumed fuel that
would otherwise be more perfectly brought into combustion. To
remedy this and to effect my improvements, I construct a fire-grate of a
series of parallel bars running from back to front on the bottom of the
grate, and extended vertically or in a vertical direction in the front
thereof. These bars are fixed or rigid and may be constructed separately
or connectedly, or a portion thereof, as occasion may require, and at
such distances apart as may be found most suitable. I then fix on a

page_text: hinge at the back of the grate another set of bars or grid, which grid is
capable of being moved up and down with its several bars passing
intermittently between the bars of the fixed or rigid portion of the grate.
This moveable grid can terminate in front of the fire-grate, either in
the form of a stand or platform for domestic purposes, or in the form
of a handle or other ornament, whereby the desired up-and-down
movement of the grid can be obtained. By which means the fire is, to
to speak, riddled as well as broken up, and no portion of fuel larger
than the size of the aperture or interstices between the bars of the
moveable and fixed grids can pass through the bottom of the grate into
the waste pan. A more complete combustion of the fuel thereby takes
place, resulting in considerable economy thercof. A much clearer fire
can be obtained in consequence of the "riddling
process before
mentioned, whereby the bottom of the grate is prevented from choking
with dirt or ashes, and a free passage is provided for a proper supply of
fresh air entering the grate, thus preventing a large amount of smoke,
and securing other advantages, such as cleanliness and unobstructed
radiation of the heat.
"
The second part of these improvements is a modification of the
foregoing, and consists in adapting a moveable or rocking grid to the
bottom of existing fire-grates, irrespective of the shape of the front bars
thereof. In carrying out this part of my improvements, I construct the
bottom of fixed or rigid bars running parallel to each other, and at
suitable distances apart from side to side of the fire-place. Underneath
these fixed bars hinges are formed, upon which turn the rocking grid in
such a manner that the same is capable of receiving a rocking motion,
the bars thereof passing intermittently between the fixed or rigid
portions of the grate bottom.
To keep the moveable grid in a horizontal position when at rest, a
weighted lever is formed in a pendant or other suitable position upon
one end of the rocking shaft or hinge, the other end of which terminates
in a handle or other ornament by which the requisite motion may be
given to the moveable gird or bars.
