VAN BERKEL, of 54 Boezemsingel, Rotterdam, Holland, Engi-
neer. Improvements in meat-slicing machines.

Claims.-—(l.) A meat-slicing machine having a table upon
which the meat is secured and carried backwards and forwards
in front of a rotating circular knife adapted to cut the meat

lated from the table-driving mechanism, the said feed-lever
being connected to and operating the feed pawl and ratchet
gear, the table being also provided with means for automatic-
ally lubricating said rails or bars as it moves back and for-
ward thereon, substantially as described.

No. 25455.—16th January, 1909.—OLIVER-ROCHE COM-
PANY, a corporation organized under the laws of the State of
New York, having its principal place of business at l Madison
Avenue, New York, United States of America (assignees of
John Roche, of l Madison Avenue, New York, aforesaid,
Engineer, and Albert Oliver, of 1296 Pacific Street, Brooklyn,
New York aforesaid, Builder). Improvements in water-
filters.

Claims.-(1.) A water-purifier having a settling-tank for
holding impounded water, and a filtering-tank arranged to
float in such impounded water, and having a bottom consist-
ing of a filtration-bed. (2.) Apparatus under claim l having
air-chambers in the filtering-tank, and means for automatic-
ally introducing ballast into said chambers to compensate
for the increased frictional resistance in the filtration-bed.
(3.) Apparatus under claims 1 and 2 having a by-pass pipe
leading from the inlet-pipe to said air-chambers, and a float
controlling a valve in said by-pass pipe, and actuated by
variations in the volume of discharge of water from the
filtering-tank, and serving to open the valve in said by-pass
pipe to conduct water into said chambers when the flow of
purified water from said tank falls below normal.

No. 25456.—16th January, 1909.—OLIVER-ROCHE COM-
PANY, a corporation organized under the laws of the State

(assignees of John Roche, of l Madison Avenue, New York,
aforesaid, Engineer, and Albert Oliver, of 1296 Pacific Street,
Brooklyn, New York aforesaid, Builder). Improvements
in water-purifiers.

Claims.-(1.) The method of purifying water consisting in
first impounding the water to permit the heavier matters to
be precipitated by sedimentation, and then completing the
purification by upward filtration under static pressure.
(2.) In carrying out the process in claim l, the method of
automatically increasing the static pressure to overcome the
increasing frictional resistance in the filtering-medium.
... (5.) Apparatus for carrying out the method of
the foregoing claims, comprising a settling-tank, and a sus-
pended filtering-tank therein having a filtration-bed in its
bottom.

No. 25462.—16th January, 1909.—KILLINGWORTH WILLIAM
HEDGES, of 10, Cranley Place, South Kensington, London,
England, Civil Engineer. Improvements relating to gas-
heating stoves.

Extract from Specification.—According to my invention I
interpose a chamber or box between the stove-outlet and the
heating-pipes and main flue, in the diagonal wall of which
box a suitable valve is provided to cut out the heating-pipes
or the like and connect the outlet direct to the flue, means
being provided whereby the position of such valve is indi-
cated, and in some cases arranged to govern the position or
operation of the gas-regulating valve.

of the claims.]

No. 25491.—27th January, 1909.—DAVID HONEYWOOD, of
120A Queen's Road, Battersea, Surrey, England, Engineer,
and GARRATT PAYNE, of 6 Homefield Road, Chiswick, Middle-
sex, England, Engineer. Improvements in machinery for
crushing or grinding ore, rock, cement, and the like.

Extract from Specification.—This invention consists in pro-
viding the compression-cylinder and stamp-cylinder with such
an arrangement of ports, valves, and passages as to effect
the holding of the stamp-head in suspension or raised during
part of the period of compression in the compression-cylinder,
and to then allow the cumulative pressure above the stamp-
piston to give a strong and swift impulse to the stamp-
piston, owing to a sudden release of the pressure below the
stamp-piston. This action is principally brought about
according to these improvements by providing the compres-
sion-cylinder with an inlet-port a little below the middle of
its length, adapted to be uncovered and covered by the
piston (the cylinder being also provided, if desired, with a
relief-valve at or near one or both its ends, as common prac-
tice may show to be necessary or advantageous). The lower
end of the stamp-cylinder is connected to the compression-
cylinder by two ports or passages formed more or less in the
form of a Y, one port or passage opening into the compres-
sion-cylinder at about the level of the inlet-port referred to,
and the other port or passage opening into valved chamber
in the lower end of the compression-cylinder. In connection
with these primary improvements, certain accessory devices
working on known principles may be provided, as, for instance,
a valve for relieving the compression in any particular stamp
of a battery for the purpose of putting such stamp out of
action, also a gear for rotating or oscillating the stamps or
the mortars. The piston of the stamp-chamber may be
provided at its upper end with an annular valved chamber.

No. 25495.—27th January, 1909.—ALFRED GODING, of
Pembroke Street, Surrey Hills, Victoria, Australia, Farmer.
Improved steam-generator for motor-cars and other purposes.

Claims.-(l.) A steam-generator wherein the temperature
is regulated or governed by the expansion and contraction of
a vertical cylinder operating, through the medium of a down-
wardly depending rod and levers, a valve controlling the
vaporised-fuel supply, the said cylinder receiving the water
in the first instance and delivering such fluid in the form of
moist steam or vapour to the generator-tubes, substantially
as and for the purposes set forth. (2.) A steam-generator
comprising an outer shell, a water-valve set in a distributing-
box, an expanding cylinder, an outlet-pipe from the cylinder,
a series of coils surrounding the cylinder, a burner beneath the
coils, and means through which the vaporised-fuel supply is
controlled by the operation of the expanding cylinder, sub-
stantially as described. (3.) In steam-generators, means for
controlling the vaporised-fuel supply comprising an ex-
panding cylinder which receives water and delivers steam, a
needle-valve 60, a spring 61, an adjusting-screw 62, and
levers and connections between the expanding cylinder and
the needle-valve, substantially as and for the purposes set
forth. (4.) In steam-generators, means for controlling the
vaporised-fuel supply, comprising an expanding cylinder
