No. 11594.—1st May, 1899.—THOMAS HODGKINSON, of 53,
Esk Street, Invercargill, New Zealand, Brickmaker. Im-
provements in kilns for burning bricks and general clay-
ware.

Claim.—(1.) In a kiln for burning bricks or general clay-
ware, the combination of a kiln (having no underground
flues), of small flue-ends, such as G, G, G, for starting the
flues from, such as H, H, which are formed out of the
materials to be burnt, with the stacks, such as E, and with
spy-holes for observing the state of the burning, such as
L, L, substantially as described and explained, and as illus-
trated in the drawing. (2.) A plain kiln formed with a flat
floor, fire-holes, and a number of small short flues in the
end wall or walls communicating direct to the stacks, such
as B, B, D, D, G, G, E, E, so that the contents to be burnt
form the chief part of the flues, the said kiln containing a
number of spy-holes, such as L, L, all substantially as de-
scribed and explained, and as illustrated in the drawing.

No. 11600.—5th May, 1899.—PERCY ADOLPHUS VAILE,
Solicitor, and ERNEST BERTHOLD VAILE, Estate Agent, both

Claim.—In a tap, the stopper C, which, upon the lever F

No. 11605.—11th May, 1899.—ARCHIBALD ANDERSON
DICKSON, of Spadina Road, Toronto, Canada, Manufacturer.
Improvements in the manufacture of peat-fuel.

Claims.—(1.) The art, method, or process of manufacturing
peat into blocks, which consists essentially in the following
sequence of operations: viz., first, drying the raw peat
sufficiently to deprive it of all but approximately the atmo-
spheric degree of moisture; second, breaking or separating it
into fragments which retain the natural fibre practically un-
broken; third, disposing such dry and broken material in
even successively-gravitating charges, and subjecting each of
such charges to pressure—one compression to each charge—
against a yielding resistance, whereby the initial pressure
upon each charge forms same into a block, and whereby
such formative pressure upon a succession of such blocks
shall always be the same, irrespective of varying density in
the charges, and whereby the formation—one upon the
other—of evenly hard separate blocks may be con-
tinuously carried on contemporaneously with the feed
of raw material, substantially as set forth. (2.) In a
press, the combination with a main frame, for carrying the
deadweight and staying the parts, of a main shaft
having a crank and fly-wheel, journals therefor inde-
pendent of the main frame, a connecting-rod and cross-
head in operative connection with the crank, a steam-cylin-
der having its piston-rod projecting therefrom at both ends,
one end of said piston-rod being connected to the cross-head,
and the other end of said piston-rod left free to act as former
or male die, a die-block having a forming-tube or female die
therein, and tie-rods connecting the crank-shaft bearings
and the die-block in such manner that each may afford
support to the other in the line of working-strain, substan-
tially as and for the purpose set forth. (3.) In a press, the
combination with a main frame, for carrying the deadweight
and staying the parts, of a crank-shaft provided with two
cranks mounted at right angles to each other, journals there-
for independent of the main frame, connecting-rods and
cross-heads in operative connection with said cranks, guides
for said cross-heads, steam-cylinders having their piston-rods
projecting therefrom at both ends, said piston-rods forming
connection with the cross-heads at one end and terminating
in formers or male dies at the other end, a die-block having
forming-tubes or female dies therein, and tie-rods connect-
ing the crank-shaft bearings and the die-block so that each
may afford support to the other in the line of working-strain,
said tie-rods also intermediately supporting the steam-cylin-
ders and cross-head guides, substantially as and for the
purpose set forth. (4.) In a press adapted to form a succes-
sion of blocks against a yielding resistance, the combination
with a suitably journalled main shaft, and means for im-
pacting motion and power thereto, of formers or male dies
in operative connection with said main shaft, a die-block
having forming-tubes or female dies therein, registering
with said formers or male dies, tie-rods between the main-
shaft journals and the die-block arranged so that each
shall support the other in the line of working-strain, and
means whereby the length of stroke between male- and
female-die members may be regulated, substantially as and
for the purpose set forth. (5.) The combination with driving
mechanism and supports of the formers or male dies, the
