contact, means for opening and closing the levers upon their
axis, and a recess formed on the internal face of each shear-
plate and extending inwards from the front edge thereof,
such recess having a straight cutting-edge adapted to lie in
a parallel line with the corresponding edge of the other
shear-plate when the levers are closed, substantially as
specified. (2.) In means for splitting and splaying metal
bars, the combination with the appliances as set forth in
claim 1, of a power-shaft, a pair of eccentrics secured
thereon, and a pair of straps surrounding the respective
eccentrics, to which straps the free ends of the respective
levers are articulated, substantially as specified.

No. 20435.—7th December, 1905.—Tom Taylor, of Cam-
bria Road, Devonport, New Zealand, Torpedoman. An
improved non-refillable bottle.*

Extract from Specification.—This invention is intended to
provide a bottle-neck so made that on its being opened it
will be shattered, whereby it will be rendered useless for re-
filling with the same kind of spirits, wine, or other liquid
which it contained before it was opened. This shattering is
caused by a screw-stopper threaded to reciprocally screw into
or around the threaded neck of the bottle, with a pawl fitted
into the stopper in such a manner that the stopper cannot
be unscrewed or screwed off without breaking and shattering
the neck.

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

No. 20458.—15th December, 1905.—Archibald Burrell
Robertson, Engineer, and Robert William Bond, Builder,
both of New Plymouth, New Zealand. Improved cow-
bailing appliances.*

Claims.—(1.) In cow-bailing appliances, the combination
with a bail-frame, comprising vertical members, of a yoke
formed of a length of metal bent into inverted U-shape sus-
pended between such vertical members, and the lower ends of
which are bent outwards and fit within guides in the vertical
members, substantially as specified. (2.) The improved cow-
bailing appliance, substantially as described and explained,
and illustrated in the drawings.

No. 20545.—9th January, 1906.—Percy Wright, of Clark
Road, Berea, Durban, Natal, Engineer. Improved gold,
precious stone, and base metal extractor.*

Claims.—(1.) An improved device for separating metals
and precious stones from their gangues, consisting of a
parallel series of three or more semi-circular troughs, each
provided with a horizontal shaft carrying a series of blades,
so constructed and arranged that the central shaft revolves
in a direction opposite to that of the other two, for the
purpose of accelerating or arresting the flow of the material,
substantially as described and illustrated in the drawings.
(2.) In an improved device for separating metals and precious
stones from their gangues, a series of three or more trans-
verse horizontal, semi-circular, continuous basins or troughs
with their inclined bottoms, catchment grooves, and central
outlets, in combination with a corresponding series of
revolving shafts and blades, for the purpose set forth, and
substantially as described and illustrated in the drawings.

No. 20555.—10th January, 1906.—James Harris Booth,
of Great South Road, Jumbunna, Victoria, Australia, Black-
smith. Improved turn-coupling for the fore-carriage of
vehicles.*

Extract from Specification.—My improved turn-coupling
is constructed of two metal rings, one fitting neatly within
the other, the upper one being secured to the vehicle-frame,
and the under one to the axle or fore-carriage; and said
coupling-rings are provided with ears or lugs, to allow of
their being secured in position by clamps, and hence without
the aid of screws or rivets. Said coupling-rings are held
together by a peculiar sliding lock-bar, which, with the other
parts, will be fully described, aided by a reference to the
sheet of drawings.

No. 20610.—20th January, 1906.—Thomas Bassett, of
Christchurch, New Zealand, Merchant (nominee of Cyrus
H. McCormick, of Chicago, United States of America,
Manufacturer). Improvements connected with the draft of
binders, reapers, and grass-cutters.*

Extract from Specification.—The construction consists of
a stump tongue or pole, upon the forward end of which I
mount a pair of small carrying wheels, which form a truck
to bear the forward weight of the machine. The stalk of
the truck is rotatably mounted in a socket-piece in the end
of the pole, and the draft pole proper is attached to the
stalk with a hinge, to permit of motion of the draft pole in a
vertical plane.

No. 20915.—29th March, 1906.—Thomas Walters, of
Bowen Terrace, Brisbane, Queensland, Australia, Plumber
(nominee of John Ballentyne Henderson, of Mary Street,
Brisbane, aforesaid, Coppersmith, and himself). Improve-
ments in bottle and other container devices to enable
opening and prevent fraudulent refilling.*

Extract from Specification.—The bottle-neck A is shaped
inside in any manner suitable for the receipt of a cork or
stopper B, but with the addition of a groove C near the top
or rim D, the internal diameter E above the groove being
greater than that, F, below it. The cork is driven in below
groove C, or below part of it. As shown, its top is a slight
distance above the groove lower edge. The seal is then
placed in the bottle-neck over the cork. Usually there is
inserted a metal disc or seal of tin-plate, steel, or suitable
material, so arranged that it is expansible in diameter under
pressure.

No. 20979.—10th April, 1906.—George Claydon, of
Buffon Street, Waltham, Christchurch, New Zealand, En-
gineer. Improved building construction.*

Claims.—(1.) In the construction of a wall wherein hollow
blocks are employed, uprights consisting of studs and plates
secured upon each side of the studs for retaining the blocks
in position, substantially as set forth. (2.) In the construc-
tion of a wall in which hollow blocks are employed, iron
uprights of H section for retaining the blocks in position,
substantially as set forth. (3.) In the construction of a wall
in which hollow blocks are employed, iron uprights of a cross-
section, substantially as set forth. (4.) The combination and
arrangement of parts comprising the improved building
construction, substantially as and for the purposes set forth,

No. 20982.—11th April, 1906.—David Anderson, of Cots-
wold Cottage, Cotswold Road, Westcliff-on-Sea, Essex, Eng-
land, Engineer. Improvements in or relating to incandescent
mantles and burners therefor.

Extract from Specification.—According to this invention
the mantle is constructed in the form of a tubular or channel-
shaped annulus, preferably contiguous. It may also be in
the form of a hollow disc, saucer-shaped, or more or less
curved or flattened, and with a central hole. In other forms
it may generally be considered to be somewhat in the form
of a pneumatic tire around a hub or wheel-like support,
the hub constituting the gas supply. All these forms will
be referred to as an annular saucer-like mantle, this term
being employed for simplicity, and also for the reason that
it more nearly describes the form which is shown in the
preferred constructions. Some of the modified forms are,
however, illustrated. The plane in which the mantle is dis-
posed may be either vertical, horizontal, or at any suitable
angle. The supply of gas and air may be directed into the
annular saucer-like mantle at a suitable point or points,
or by a continuous opening or series of openings, and such
supply is situated on the smaller circumference of the
annulus or intermediate between same and the larger cir-
cumference, and in such manner that the flame is directed
downwardly and outwardly or in a substantially transverse
or horizontal direction and outwardly from the centre of the
burner head, the flame or product of combustion preferably
issuing between the outer circumference of the mantle and
the circumference of the burner-head, so that the flame need
not pass through the wall of the mantle. In some forms
