denum, or of a mixture of these substances, heating it, or
its cutting-portion, to a temperature of or over 1,725° Fahr.,
then cooling the tool rapidly to a temperature below 1,550°
Fahr., and afterwards maintaining the tool at temperatures
between 1,350° Fahr. and 450° Fahr. for several minutes.
(11.) The method of producing a metal-cutting tool adapted
to retain its efficiency at high temperatures which consists
in forming the tool of air hardening tool steel containing not
less than one-half of 1 per cent. of chromium and not less
than 1 per cent. of tungsten or molybdenum, or of a mix-
ture of these substances, heating it, or its cutting-portion, to
a temperature of or over 1,725° Fahr., then cooling the tool
rapidly to a temperature below 1,550° Fahr., and afterwards
maintaining the tool at temperatures between 1,240° Fahr.
and 700° Fahr. for several minutes. (12.) The method of
producing a metal-cutting tool adapted to retain its effi-
ciency at high temperatures which consists in forming
the tool of air hardening tool steel containing not less
than one-half of 1 per cent. of chromium and not less
than 1 per cent. of tungsten or molybdenum, or of a mix-
ture of these substances, coating the portion of the tool to
be treated with a fusible slag, and then heating the tool
to a temperature over 1,725° Fahr., and sufficient to melt
the slag coating. (13.) The method of producing a metal-
cutting tool adapted to retain its efficiency at high tempera-
tures which consists in forming the tool of air hardening
tool steel containing not less than 1 per cent. of chromium
and not less than 4 per cent. of tungsten or its equivalent,
as specified, and heating it, or its cutting-portion, to a tem-
perature of or over 1,725° Fahr.

No. 13335.—28th January, 1901.—FREDERICK FARGO
CHURCH, of Rochester, New York, United States of America,
Lawyer (assignee of Alfred J. Gillespie, of Rochester afore-
said, Inventor). Improvements in voting-machines.

Extract from Specification.—My present invention has for
its object to provide an improved voting-machine, by means
of which the voter may indicate in secret the ballots he
desires to cast, whether what is known as a straight ballot,
involved all the candidates of a party, or a split ballot, in-
volving votes for candidates nominated or indorsed by differ-
ent parties, and then may simultaneously register all of the
votes or ballots indicated by him, when or after leaving the
proximity of the indicating-devices; and it further consists in
the embodiment in the machine of suitable interlocking de-
vices, whereby the voter is permitted to indicate and cast
ballots for only a predetermined number of candidates for an
office. It further consists in devices whereby he may be
permitted to cast or indicate ballots for persons not nomi-
nated by any of the regular parties, or whose names do not
appear upon the ballot-sheet or ticket; and, further, in de-
vices by which he may indicate his will with regard to ques-
tions for and against which a popular vote is desired. It
further consists in certain improvements relating to balloting-
devices for candidates nominated or indorsed by two or more
parties, whereby a vote for such candidate is registered but
once, although the voter may indicate a ballot in several
places where the candidate’s name appears. It further con-
sists in the provision of means for preventing tampering with
the machine and insuring the proper operation of some or
all of the ballot indicators to voted position, although the
voter may retract or withdraw any votes thus indicated, and
may alter and arrange the ticket he desires to vote, to his
satisfaction, before leaving the proximity of the indicating-
devices, all as will be hereinafter fully described, the novel
features being pointed out in the claims at the end of this
specification.

[NOTE.—The number and length of the claims in this case
prevent them from being printed, and the foregoing extract from
the descriptive part of the specification is inserted instead.]

No. 13337.—28th January, 1901.—WILLIAM MEDHURST, of
Pahiatua, New Zealand, Saddler. Improved means for
securing covers to horses and other animals.

Claim.—(1.) In means for securing covers to horses and
other animals, a pair of straps secured to the rear end of the
cover, and fastened together so as to form a double loop, to
which a spring hook is affixed, in combination with another
pair of straps secured to the inside of the cover, about mid-
way between its ends, the free ends of such straps being pro-
vided with links adapted to fit into the spring hook upon the
rear pair of straps, as specified, and as illustrated in the
sheet of drawings.
(Specification, 2s.; drawings, 1s.)

No. 13345.—24th January, 1901.—JOHN ERNEST LELLIOTT
CULL, of Dunedin, New Zealand, Engineer. Improved
apparatus for separating magnetic from non-magnetic
materials.

Claims.—(1.) In the separation of magnetic from non-
magnetic substances, the combination of a belt C with a
pulley A, A¹, the said pulley being magnetized by a current
of electricity passing through insulated wires wound round
the bosses of the parts forming the pulley, for the purpose of
separating magnetic from non-magnetic substances, the
latter falling away by gravitation, and the former being held
to the pulley till the belt leaves it, substantially as described
and explained, and as illustrated in the drawing. (2.) In
combination, pulleys A and A¹, having coils for carrying a
current of electricity wound round the bosses, with a belt on
which the substances to be separated are delivered, and the
arrangement by which the pulleys are separated by insulating-
substance F, F, for more evenly distributing the magnetic
force over the pulley, all substantially as described and
shown, and for the purposes as set forth.

No. 13347.—29th January, 1901.—THOMAS COOK BAYLDON,
of Thames, Auckland, New Zealand, Master Mariner and
Harbourmaster. An invention for preventing the teredo
worm and other marine insects destroying wharf- and bridge-
piles, and other timber used in wharf- or bridge-construction;
or timber used generally for marine purposes of any de-
scription.

Claim.—The coating of the surface of wharf- and bridge-
piles and other timber used in erecting such structures, im-
merged or partially immersed in water, with a composition
consisting of ground glass or glassy sand mixed with coal-tar
or other suitable paint or oil, and then covering the piles or
other timber in such a manner as to prevent the composition
getting rubbed off while the piles are being driven or placed
in position, and so preserving the piles and other timber from
being destroyed by the attacks of the teredo worm and other
marine insects, and thus preventing the teredo and other
marine insects from boring and otherwise destroying the
piles and other timber used in building wharves, bridges,
and other structures erected for the use of shipping, roads,
and other purposes where the teredo worm and other in-
sects exist.

No. 13352.—19th January, 1901.—ROBERT COCKERELL, of
Dunedin, New Zealand, Blacksmith. Improved horizontal
centrifugal puddling and amalgamating screens and tables
for dredges and batteries.

Claims.—(1.) In gold-saving tables, the combination of the
circular, reciprocating, and up-and-down twisting motion for
forcing the heavier particles to the outer rims by centrifugal
motion, whilst the tailings are forced to the centre, sub-
stantially as described and as shown in the drawings. (2.) In
combination, tables formed of endless races on sleeves D,
rising and falling by a twisting motion by being hung on
chains F, the wash being broken by the spikes on the upper
screen D³, and being delivered at the outer part of the outer
race over the mercury, when the heaviest portions work to
the outer parts and the tailings are forced to the centre and
discharged, all substantially as shown and described, and as
illustrated in the drawings.

No. 13353.—28th January, 1901.—JAMES TROUP, of 147,
Salisbury Street, Christchurch, New Zealand, Engineer,
Improved spouting-bracket.

Description.—The bracket consists of two pieces of metal.
One piece is bent to support spouting at foot, and, after being
carried up between the spouting and the wall, is turned over
the top of the former, projecting nearly to its edge. The
other piece has one end curved to catch the edge of the
spouting, and the other end is provided with a slot cor-
responding with a slot in the end of the first-mentioned
piece. A bolt fastened by a nut passes through the slots.

Claim.—A bracket for securing spouting over the top of
same by means of adjustable pieces, substantially as men-
tioned and described.
