against which a sliding block supporting the said die is adapted
to strike to force the outside-forming dies against the bent
blank and squeeze the heel-portions of the same tightly on the
said inside-forming die. Directly the blank has been given
the desired shape a press or hammer is operated by a cam and
rocking-beam to flatten and seat the formed shoe. During the
time the hammer is bearing on the formed shoe the continued
operation of the eccentric is returning the pitman rod to its
original position, and in order to permit of it doing this a
loose connection is effected between the outer end of said rod
and the block to which the inside-forming die is affixed.

No. 30504.—16th November, 1911.—WILLIAM THOMAS
CLIFFORD, of Hollinsworth, Perouse Road, Randwick, New
South Wales, Australia, Warehouse-manager. Combined vest
and apron.*

Extract from Specification.—In carrying out this invention
I fashion a body-portion or vest like an ordinary waistcoat
with or without sleeves, and to the bottom of one side-piece
thereof in the front I permanently attach the upper edge of
one half of an apron, the other half of which is a loose flap,
and which I provide with means for detachably securing it
to the other side of the body-portion or vest when the latter
is on the body.

No. 30517.—17th November, 1911.—JOHN KELLY, of Forth
Street, Invercargill, New Zealand, Engineer. Improvements
in sectional concrete construction.*

Extract from Specification.—The invention consists, broadly,
in the use of moulded slabs of concrete provided with rein-
forcing-rods embedded within them and projecting from the
edges to be joined, arranged edge to edge with spaces between
and with the reinforced rods overlapping one another, and
then in moulding concrete within such space so as to surround
the rod-ends and thus lock the slabs firmly together. This
operation is carried out by the arrangement of suitable moulds
around the slab-edges into which the concrete is poured, so
that when set the moulds may be removed. The moulds may
be made of any desired shape to form abutments upon both
or either sides of a wall to make a flush joint with the slabs,
or to make girders or beams to support the slabs in roof or
floor structures. The moulded joint may also itself be
reinforced by means of rods arranged longitudinally within
it and interlocking, if desired, with the reinforcement-rods
of the slabs.

regulating thermostat for incubators and the like.

Claims.—(1.) A tube made of non-conducting material
fitted and enclosed with a number of metal rings and rings of
non-conducting material alternately, as shown in Fig. 2.
(2.) In combination, a sliding metal contact-ring, as shown on

(Specification, 2s. 6d.)

No. 30817. — 31st January, 1912. — JOHN DOUGAN, of
Dunedin, New Zealand, Sergeant of Police. Ventilating-frieze
for blinds.*

Claim.—(1.) In blinds of the class described, a ventilating-
frieze, ornamental or plain, having an upper bar for attach-
ment to a roller, and a double lower bar for attachment to
a blind, for the purpose described and as illustrated.

(Specification, 2s. 3d.)

[NOTE.--Here follow two other claims.]

No. 30833.—7th February, 1912.—FELIX JOSEPH SCHUR-
MANN, of 7 Burchardstrasse, Munster, Westfalia, Germany,
Manufacturer. Hose-couplings of compressed-air conduits
for railway-brakes.

Claim.—In a hose-coupling of compressed-air conduits for
railway-brakes, in combination, two coupling-halves, each
having a hose-joining member, and a cock therein; a member
consisting of guides, handle, and steering-means for said cock
movably attached to said joining-member, and adapted to
effect coupling at a simultaneous control of the closing-mem-
bers; flanges of said coupling-halves having pins and recesses,
and adapted when engaged to rest immovably upon each
other; and means, upon the movable coupling-member (1) with
its handle being turned, to shift said guides above each other,
and at the same time to close or open the passage-ways of the
coupling by said steering-means, substantially as and for the
purpose set forth.

(Specification, 4s. 6d.)

No. 30862.—14th February, 1912.—HENRY ERNEST MET-
CALFE, of Auckland, New Zealand, Civil Engineer. Improve-
ments in apparatus for the treatment of sewage.

Extract from Specification.—The invention consists, broadly,
in the employment of a rotating valve of special construction,
adapted to connect any one of a number of pipe-branches
leading to the different filter-beds with the main sewage-pipe,
and also of a rotating valve adapted to connect any one of a
number of discharge-pipes, leading from the different filter-
beds, with a main discharge, each of such valves being auto-
matically actuated to connect the main with the respective
branches in turn by mechanism set in motion by apparatus
intermittently delivering water to it. This apparatus may
consist of a tipping-bucket adapted to be filled in a variable
period of time, and, when filled, to tip and discharge its con-
tents, or siphon apparatus adapted to automatically flush
at stated intervals of time. The approved form of mechanism
for actuating each of the valves consists of a bucket suspended
on a pulley and counterweighted so as to keep it raised when
empty, and adapted to fall when filled, and to then discharge
itself. The wheel is loosely mounted on a shaft geared with
the valve, and adapted to lock with the shaft when it is
revolved by the falling of the bucket, and to run freely when
the bucket is being raised again by its counterweight.

No. 30902.—19th February, 1912.—FRANK WYNON VICKER-
MAN, of St. John’s Hill, Wanganui, New Zealand, Manager.
Improvements relating to the extraction of casein from milk.*

Extract from Specification.—I employ a rectangular wooden
vat which is relatively long to its width and is deeper at one
end than the other, the bottom thereby having a comparatively
steep incline. Steam-pipes near the bottom of the vat are
arranged in rectangular form approximating to the contour of
the sides and ends of the vat. The perforations in the pipes
are directed towards the bottom of the vat, thereby pre-
venting churning and bubbling of the milk.

No. 30908.—16th February, 1912.—ALFRED LAUNCELOT

Inventor. Improved pegs, especially for clothes-pegs.

Claim.—(1.) In clips, especially for clothes-pegs and the
like, wire clips of wire bent to nearly two complete turns,
said turns somewhat open at their lower edges to introduce
the articles to be clipped, and closer at their upper edges to
clip tightly, the said wire extending and formed into a hook
after being twisted with the other and shorter end, all sub-
stantially as described and as explained, and as illustrated in
the drawing.
