or in claim 2, in which the block of high-resistance material
is surrounded laterally by relatively incombustible material¹,
e.g., asbestos, substantially as and for the purpose herein-
before described. (4.) A constructional form of the elec-
trode claimed in claim 3, in which the incombustible
material is adapted to be removed in annular sections,
substantially as described. (5.) The combination with an
electrode, such as that claimed in claim 1, of a cooling means
for the holder for the block of high-resistance material, sub-
stantially as described. (6.) An electrode such as that
claimed in claim 1, in which the holder for the block of high-
resistance material is provided with heat-radiating flanges,
substantially as described. (7.) A constructional form of the
apparatus claimed in claims 5 and 6, in which means are
provided for directing a blast of air on to the heat-radiating
flanges, substantially as described. (8.) A constructional
form of the electrode claimed in claim 1 or in claim 6, in
which the holder for the high-resistance material is made with
a relatively enlarged terminal portion, substantially as
described. (9.) The several forms of electrode constructed
substantially as described with reference to the drawings, for
the purposes specified.

No. 24667.—14th July, 1908.—ROBERT JAMES SMITH, of
57 Church Street, Masterton, New Zealand. Improvements
in mortise-locks.*

Extract from Specification.—According to my invention,
the cylindrical bolt fitting this casing is normally projected
by a coiled spring, and is operated inwardly by a cam pro-
jecting from a tubular rocking-spindle. A spring-operated
locking-lever, pivoted within the casing, is located in a
recess in the bolt, and can be operated to cause its end to
engage a shoulder in the bolt and lock it in its projected
position. The lever is operated by a pin passing through
the cam and into the tubular rocking-spindle referred to,
within which is a tumbler operable by a key passed into
the rocking-spindle, said tumbler having a cam adapted to
engage the end of said pin.

[NOTE.—The above extract from the specification is inserted in
place of the claims.]

No. 24712.—9th April, 1908.—FREDERICK SAMUEL GREER,
of No. 7 Market Street, Sydney, New South Wales, Aus-
tralia, Manufacturer. An improved fumigator.

[NOTE.—This is an application under section 106 of the Act, the date
given being the official date of the application in Australia.]

Claims.—(1.) Improved fumigating or spraying ap-
paratus, comprising a double-action pump, a container
or generating or mixing chamber, a pipe-connection
between the two and a diaphragm cock or valve, and
extension-pipes therefrom, substantially as described and
explained. (2.) In apparatus of the class set forth
the combination with cylinder such as 7, having double-
ended piston such as 8, of inlet-valves 16 and 27, and
discharge-valves such as 19 and 31, and a chamber such as
24, and discharge-cone such as 21, substantially as described
and explained and as illustrated in the drawings. (3.) In
apparatus of the class set forth the combination with a con-
tainer or generating or mixing chamber such as 38, having
pipes 43 and 44 therein, of a cock such as 36 connecting to
said pipes, and having a diaphragm such as 40, substantially
as described and explained and as illustrated in the drawings.
(4.) The combination and arrangement altogether of the
mechanical parts or integers comprising an improved fumi-
gator or spraying apparatus, substantially as described and
explained and as illustrated in the drawings.

Improvements in machines for the manufacture of earthen-
ware pipes.

Claim.—A machine for making earthenware pipes, the
same being characterised by (a) cores so mounted that they
may be withdrawn to cut off the clay; (b) moulds which
will divide to allow the socket part of the pipe to be
removed; and (c) a table affording balance-weighted resist-

No. 24866.—1st September, 1908. — HARRY WILLIAMS
HARDINGE, of 43 Exchange Place, Manhattan, New York,
United States of America, Engineer. Improvements in
method of and apparatus for disintegrating ores and other
materials.

Extract from Specification.—In carrying out my invention
the lumps or pieces of ore or other material are subjected to
tumbling action (either with or without the addition of
non-friable crushing or grinding bodies, such as metal balls,
flint pebbles, &c.), whereby the lumps or pieces are broken
up by impact and attrition in a succession of reducing or
grinding zones of gradually diminishing reducing action,
and maintaining a substantial vertical stratification of the
material according to the size of its pieces or particles.
Stated a little differently, the material is passed through a
succession of reducing zones of successively less reducing
action, according as, or as fast as, the lumps or masses of
the material are broken up or disintegrated. In this way
the pieces of material are subjected to reducing actions
which are substantially proportionate respectively to the
sizes of the pieces, and hence, in general, to the work required
to break them up. In other words, the reducing action
