Improvements in or relating to Fire Grates for Water Gas Generators
and other Purposes.

A communication from J. EDUARD GOLDSCHMID, Banker, of 7, Friedenstrasse,
Frankfort-on-Main, Germany.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent do hereby declare the nature of this invention to be
as follows:-
In grates such as are used in water-gas generators, the whole of the coke or
coal material is often placed on a single, flat grate, extending over the full cross
sectional area of the lower part of the furnace.
Such an arrangement requires very long grate bars, and renders the working of
the fire very difficult, especially in cases where the grate can be worked from
two sides only.
.
t
In order to meet these draw-backs a special arrangement or construction of
grate is adopted according to the present invention, the grate being divided into
say four quadrants in which the grate bars are fixed parallel to each other in such
a manner that the ends of the bars are supported by a ring or frame extending
all round the furnace, while the inner ends are supported on a cross device or
plate of arms.
In such a construction the grate bars of course vary as to length, but such fur-
naces offer the great advantage that you can work them from four sides, having
to attend to only comparatively short lengths of bars, owing to which the working
of the grate is greatly facilitated. The ring or outer support round the furnace
is provided with the necessary recesses for the reception of the grate bars. In the
centre is a cross bar arrangement in connection with a hollow column arranged for
the purpose of admitting air. The outer ends of the cross bars are also supported
by the ring and the cross bar is also provided with the recesses necessary for the
reception of the inner ends of the grate bars.

Chartered Patent Agent, do hereby declare the nature of this invention and in

page_text: what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
In grates such as are used in water-gas generators, the whole of the coke or
coal material is often placed on a single, flat grate, extending over the full cross
sectional area of the lower part of the furnace.
Such an arrangement requires very long grate bars, and renders the working of
the fire very difficult, especially in cases where the grate can be worked from
two sides only.
In order to meet these drawbacks a special arrangement or construction of grate
is adopted according to the present invention, the grate being divided into say
four quadrants in which the grate bars are secured in parallel lines, the outer
ends of the bars being supported by a ring or frame extending all round the side
of the furnace, while their inner ends are supported on a cross device or plate or
arms radiating from the centre.
In such a construction the grate bars of course vary in length, but such furnaces
offer the great advantage that they can be worked from four sides, only compara-
tively short lengths of bars having to be attended to, owing to which the working
of the grate is greatly facilitated. The new construction of grate is represented in
the accompanying drawing in which a represents the ring or outer support round
the furnace, which ring is provided with the necessary recesses for the reception
of the grate bars b. In the centre is a cross bar arrangement ceec in connection
with a hollow column, through which air can be admitted. The outer ends of the
cross bars are also supported by the ring a and the cross bar is also provided with
the recesses for the reception of the inner ends of the grate bars.
Having now particularly described and ascertained the nature of the said
invention, as communicated to me by my foreign correspondent, and in what
manner the same is to be performed, I declare that what I claim is:-
1. A grate intended especially for gas generators, characterised by the grate
bars being arranged in parallel sets, the outer ends of the bars being supported
on a ring plate, and the inner ends on a cross, the arms of which radiate from
the centre of the furnace, substantially as described.
2. The complete grate for gas generators and other purposes substantially as
described or illustrated in the accompanying drawings.
