No. 19643.—24th June, 1905.—GEORGE SEATOR STEVENSON, of Gore, New Zealand, Contractor. Improvements in ratchet wrenches.*

Extract from Specification.—According to my invention
there are two ratchet discs, which have openings at one side
of the same size and are mounted in the handle of the wrench,
superimposed so that their openings may coincide. Each
disc is capable of independent circular motion, so that when
one disc is moved its closed portion eclipses or covers portion
of the opening of the other disc, and so reduces it in size.
There are several sizes of openings effected by independently
revolving one of the discs. The handle may have one pair
of discs at each end.

No. 19701.—10th July, 1905.—DUNCAN ST. CLAIR MACGREGOR, of Invercargill, Southland, New Zealand, Furniture Manufacturer. Improved means for raising and lowering curtain-poles.*

Extract from Specification.—My invention consists of a
third or guide cord in conjunction with the headboard, the
said cord leading over guide pulleys, and is connected at its
end to near the middle of the pole. The position of this
cord is such that when it is pulled it tends to draw the
pole away from the brackets referred to.

No. 19747.—13th July, 1905.—WALTER MADDISON, of Albion Hotel, Gisborne, New Zealand, Station Hand. An improved method of ear-marking live-stock.*

Claim.—For the purpose mentioned, the lines of the ear
as shown at A, together with the divisions or angles of
the ear as shown at B, forming in conjunction a series of
localities within the registration area as shown at F equal
in number to the numerals as shown within the registration
area at E, as indicated. For the mentioned purpose, any
series of three punch-marks as C placed at an angle as or
similar to that shown at B, and regulated as to their depth
as shown at A. For the purpose, any series of three
punch-marks applicable to the several angles as shown
at E. A series of three punch-marks set in various angles
and having numerical values as or similar to that shown
at D, substantially as indicated. The combination and
arrangement of the several parts specified for the purpose
of ear-marking live-stock, substantially as set forth and
indicated in the drawings.

No. 19762.—17th July, 1905.—ALBERT FIRTH JAGGER, of Stanley Point, Devonport, near Auckland, New Zealand, Ship Chandler. A metal-castings mould-dresser.*

Claim. — The dresser specified, composed of infusorial
earth or keiselguhr used as set forth and described.

(Specification, 1s.)

No. 19776.—21st July, 1905.—RALPH DUNNE, of Dunedin, New Zealand, Picture-framer. Improvements in clamps for use in making frames.*

Claims.—(1.) A clamp of the kind described provided
with two integral upright flanges thereon at an angle with
each other, with inwardly inclined inner surfaces, substantially
as described. (2.) The complete mitre-clamp, substantially
as described or illustrated in the drawing.

No. 20376.—27th November, 1905.—GARNET BOWEN HOLMES and ARTHUR DUNSCOMBE ALLEN, both of Wellington, New Zealand, Draughtsmen. Improvements in trolley-heads for overhead conductors of electric traction.*

[NOTE.—The title in this case has been altered from that set out
in the provisional specification.]

Extract from Specification.—This invention provides a
trolley-head which will not be caught in the overhead gear
of an electric tramway when the trolley-wheel accidentally
leaves the trolley-wire. This is effected by means of a petti-coat or catch on the spindle or socket which supports the
wheel worked in conjunction with some suitable lifting-device,
which device is only operative when the head has left the
tramway trolley-wire. The spring actuating the lifting-device acts partly as a cushion, with the result that the wear
on all overhead suspension work is materially reduced. A
spring clip is also used, which maintains the spindle in a vertical position until any overhead obstruction is met with, in
which case the clip is forced apart and the spindle and the
wheel fall back clear of the overhead wires. The trolley-cord is attached to the lifting-device to keep it down when
necessary; in order to prevent weight of cord being on this
mechanism a small spring is introduced. The operation of
the lifting-device is also used to give warning that the trolley-head has left the wire. In order that the trolley-wheel
may be maintained approximately in line a small rectifying-device is introduced.

No. 20436.—9th December, 1905.—HUBERT PERCY BARRY, of Waihi, Auckland, New Zealand, Engineer. Honeycomb linings for tube mills and similar grinding and crushing machines.*

Extract from Specification.—The purpose of this invention
is to provide a cheap and effective grinding-surface within
tube mills and other grinding-machines. This purpose is
attained by fitting within the tube mills or grinding-machines
shallow frames or boxes of hexagonal or rectangular form,
shaped as is stated, or in any other shape which will conveniently fit the grinding mill or machine, and fixing therein
a material composed of rough blocks of stone or other substances suitable for the purpose as described.

No. 20683.—7th February, 1906.—GARNET BOWEN HOLMES and ARTHUR DUNSCOMBE ALLEN, both of Wellington, New Zealand, Draughtsmen. Improvements relating to trolley-heads for electrical-tramway systems.*

Extract from Specification.—According to our present
invention the trolley-wheel is journalled within a jaw, which
is pivotally mounted within a bracket so as to be free to
swivel therein within certain limits, spring means being
employed to cause the wheel to normally tend to assume
a position in line with the trolley-pole. The bracket referred
to is connected to a head carried upon the end of the trolley-arm, the connection preferably consisting of pins projecting
from the head taking into slots formed in cheeks projecting
from the bracket. A pin carried by the cheeks engages,
when the trolley-wheel is in contact with the conductor
and the bracket pressed down thereby, in a slot formed
for its reception in the head. Spring means are employed
whereby when the trolley-wheel leaves the conductor the
pin referred to is drawn out of the slot and the bracket turns
upon its pivotal connection with the head, the bracket being
so placed that the action of gravity has the effect of causing
the trolley-wheel and its carrying-means to fall until it is
in such position that it will clear the overhead gear or damage
will not be caused thereto by its contact therewith. Guides
are employed for the cheeks referred to. The turning-over
of the bracket upon its pivotal connection causes contact
to be made in an electrical-bell circuit whereby indication
is given to the motorman when the trolley-wheel has left
the conductor. The conductors of the electrical circuit are
provided with plug connections whereby they may be easily
parted.
