in the Empire of Germany, Merchant.
I, WILLIAM PHILLIPS THOMPSON F.C.S. M.I.M.E. of The Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool and 6 Bank Street Manchester, both
in the County of Lancaster, 118 New Street, Birmingham, in the County of
Warwick and 322, High Holborn, in the County of Middlesex, Civil Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention has for its object to combine the advantages of furnaces having
trough-shaped receptacles for the combustible of the pattern of basket grates, with
those of the movable rocking grates (over the whole grate surface). This object
is attained according to the present invention by the furnace being formed of a
number of bowed or trough-shaped grate bars lying side by side which however
are not fixed but are suspended so as to be adapted to be rocked or oscillated to both
sides. The bowed or trough-shraped grate bars are pivotally mounted in suitably
recessed lugs by means of pins or trunnions attached to the upper ends of the bars
at both sides, and may therefore be rocked to and fro on the points of suspension.
The rocking movement is produced by means of a common rod having notches in
which engage projecting ridges or feathers formed on the under face of the grate
bars so that by moving the rod the various grate bars will be simultaneously
moved in the same direction.
The effect of the shaking or rocking is such that even large pieces of scoria or
clinker which otherwise could not fall through the interstices of the grate, are
suitably disintegrated and thus pass through the interstices into the ash pan.
This improved arrangement is of particular advantage in the case of caking-
coals which frequently form a cake of clinker, covering the whole bottom surface
of the grate, this cake is broken up by the grate bars resting stepwise one against
the other when rocked, and may then be easily removed.

Warwick and 322, High Holborn, in the County of Middlesex, Civil Engineer,
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 has for its object to combine the advantages of furnaces having
trough-shaped receptacles for the combustible of the pattern of basket grates, with
those of the movable rocking grates (over the whole grate surface). This object
is attained according to the present invention by the furnace being formed of a
number of bowed or trough-shaped grate bars lying side by side which however
are not fixed but are suspended so as to be adapted to be rocked or oscillated to both
sides. A furnace arranged in this manner is shown in the accompanying drawings
in which Figures 1 and 2 are vertical sections taken at right angles to each other.
The bowed or trough-shaped grate bars a, as may be seen therefrom, are
pivotally mounted in suitably recessed lugs e by means of pins or trunnions
attached to the upper ends of the bars at both sides, and may therefore be rocked
to and fro on the points of suspension. The rocking movement is produced
by means of a common rode having notches e' in which engage projecting ridges
or feathers a' formed on the under face of the grate bars so that by moving the rod
the various grate bars will be simultaneously moved in the same direction.

The effect of the shaking or rocking is such that even large pieces of scoria or
clinker which otherwise could not fall through the interstices of the grate, are
suitably disintegrated and thus pass through the interstices into the ash pan.
This improved arrangement is of particular advantage in the case of caking-
coals which frequently form a cake of clinker, covering the whole bottom surface
of the grate, this cake is broken up in the interstices formed by the grate bars
resting stepwise one against the other when rocked, and may then be easily
removed.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
ine by my foreign correspondent, I declare that what I claim is
A rocking grate having suspended oscillating grate-bars of bowed or trough
shape adapted to be simultaneously reciprocated or rocked to and fro on their axis
of rotation by means of a common rocking device (e) substantially as described,
and shown.
