fied. (2.) The general arrangement, construction, and combi-
nation of parts in my self-acting pipe for preventing dirty

plained, as illustrated in the drawings, and for the several
purposes set forth.

No. 19424.—4th May, 1905.—ARTHUR SAMUEL DUNMORE
CRIBB, of “Fairholme,” Milton, Brisbane, Queensland,
Australia, Mechanical Engineer. Improvements in loco-
motive engines running on bogeys.

Claims.—(1.) In improvements in locomotive engines
running on bogeys, an intermediate shaft carrying a geared
pulley adapted to engage with geared pulleys fixed centrally
upon the travelling-wheel axles as and for the purpose set
forth, and as described and illustrated by drawings.
(2.) In improvements in locomotive engines running on
bogeys, the construction of the central geared pulley con-
sisting of two halves bolted together, the inner circle having
keyways such as O slotted out laterally to receive feathers or
keys such as N formed on the under-side into pins fitting
into holes in the spherical bearing of the intermediate shaft,
as and for the purpose set forth, and as described and
illustrated by drawings. (3.) In improvements in locomo-
tive engines running on bogeys, the extension arm P
pivoted at P in combination with the connecting links such
as R, pins such as Q and Q1, blocks such as S and W work-
ing in curved and straight slots in the cross-head, as and for
the purpose set forth, and as described and illustrated
by drawings. (4.) In improvements in locomotive engines
running on bogeys, the disposition of the boiler and motor
centrally between the bogeys, as described and illustrated
by drawings.
(Specification, 5s.; drawing, 2s.)

No. 19453.—11th May, 1905.—HILARY QUERTIER, of
Woods’s Hotel, Dunedin, New Zealand, Engineer. An
improved conveyor.

Extract from Specification.—According hereto a bucket for
conveying the material travels upon a wire rope the ends of
which are secured to pulleys running upon fixed wire ropes
so that the rope carrying the bucket can be moved laterally
to bring the bucket into a convenient position for loading and
discharge. Portable means are provided for supporting the
ropes, for locking the bucket in its normal position, and for
automatically unlocking and tipping it.
[NOTE.—The above extract from the specification is inserted in
place of the claims.]

No. 19458.—9th May, 1905.—FREDERICK WILLIAM BAR-
TON, Gardener; WILLIAM MORTON, Mechanical Engineer; and
JOHN HERCUS, Agent, all of Dunedin, New Zealand. Im-
proved automatic disengaging stirrup-strap attachment.

Claim.—In devices for automatically releasing the stirrup
and its strap from a saddle on both sides of same when a
rider falls off, but which retains same securely at all other
times. In combination, a special joint consisting of a slid-
ing stud with rounded and bevelled ends working in a V
groove in the form of a C-shaped slide, the said stud being
secured to the stirrup-strap and the said slide being attached
to the saddle, the said joint thus formed being always kept
clean and ready for instant use by always working, but keep-
ing the whole firmly together at all other times, all
substantially as described and explained, and as illustrated
in the drawing.
(Specification, 3s.; drawing, 1s.)

No. 19465. — 11th May, 1905. — FREDERICK WILLIAM
BARTON, Gardener; WILLIAM MORTON, Mechanical En-
gineer; and JOHN HERCUS, Agent, all of Dunedin, New
Zealand. Improved hedge-clipper.

Extract from Specification.—For this purpose we shape
one blade so the edge presents a fluted or corrugated profile,
said corrugations being preferably deeper as they approach
nearer to the centre pin on which the blades of the shears
pivot, in regularly increasing depths, so that when said
shears are fully open the innermost corrugation shall pre-
sent such a surface that there is no tendency for the object
to be cut to spring forward out of the cut of the blades. It
will be seen that as the angle of the blades increases such
necessitate continually greater depths of corrugations to
achieve this purpose, and vice versa, so that very shallow
corrugations are sufficient at the outermost end or point of
the blade.
[NOTE.—The above extract from the specification is inserted
in place of the claims.]

No. 19468.—15th May, 1905.—WILLIAM ERNEST HUGHES,
of Queen’s Chambers, Wellington, New Zealand, Patent
Agent (nominee of Thomas Steel Perkins, of 407, Whitney
Avenue, and Ray Philip Jackson, of 429, Kelly Avenue,
Wilkinsburg, Pennsylvania, United States of America, Elec-
trical Engineers). Improvements in or relating to multiple-
unit control for electric motors.

Claims.—(1.) In a system of multiple-unit control for elec-
tric motors of the kind in which the motor circuits are
governed by a reversing-switch and a drum-controller the
movements of which are electrically governed by a master
switch, the arrangement for controlling the operation of the
drum-controller whereby a circuit is completed through a
magnet for retaining the drum-controller in the first posi-
tion of the master switch, and in subsequent power-posi-
tions of the master switch the circuit of the retaining-
magnet is maintained, and by means of separate contacts on
the master controller corresponding to the several power-
positions a circuit is completed through a magnet for
actuating the drum-controller by way of separate sets of
contacts on the latter corresponding to each power-posi-
tion of the master switch, each set being arranged to
maintain the circuit of the actuating-magnet through such
a series of step movements of the drum-controller as may be
desired in each power-position of the master switch, sub-
stantially as set forth. (2.) In a system of multiple-unit
control for electric motors in which the drum-controller is
actuated by an electro-magnet, the arrangement of a variable
or invariable discharge resistance connected in shunt to the
actuating-magnet, substantially as and for the purpose
or purposes set forth. (3.) In a system of multiple-unit
control for electric motors in which the controller-drum
is rotated in a forward direction by an electro-magnet, the
arrangement for making and breaking the circuit of the
actuating-magnet comprising two electro-magnets which
are alternately energized through the operation of the drum-
controller actuating-magnet, substantially as described.
