[No. 3

venting reversal of the machine element, and two separate
means for freeing said machine element from the retaining
device, one of which means is operated by the machine ele-
ment alone and the other of which is controlled by movement
of the impelling means. (2.) The selective mechanism de-
scribed in claim 1 hereof, wherein the two freeing means are
arranged so that one (which is retarded in action) may be
utilised at will to prevent operation of the other freeing means.
(3.) A selective mechanism comprising a reversible ratchet-
wheel, a retaining pawl therefor mounted so as to move
laterally, and automatic means operated by reverse move-
ment of the ratchet-wheel for moving said pawl laterally out
of engagement with said wheel. (4.) A selective mechanism
comprising a reversible ratchet-wheel, a device for driving the
same, a retaining pawl, a hook for the pawl, and a separate
retarded means for tripping said hook controlled by the de-
vice which drives said wheel. (5.) A selective mechanism
comprising a reversible ratchet-wheel, some of the teeth of
which are bevelled across a portion of their faces, and a pawl
arranged to be moved out of engagement with the wheel by
the thrust of said bevelled teeth. (6.) The construction set
forth in claim 3 hereof wherein some of the teeth are bevelled
across their tops and others across their bases, in combination
with means for raising and lowering the pawl so that it en-
gages with the upper or lower parts of the teeth at will. (7.)
A selective mechanism of the class described wherein the re-
tarding agent comprises an inertia-wheel which is made to
rapidly revolve while rolling slowly in one direction on a track,
but can be quickly slid backward on said track without
material rotary movement. (8.) A selective mechanism of
the class described in which a ratchet-wheel is operated by a
pawl-bearing lever connected to a bowed spring so mounted
as to be straightened by movement of a magnet armature.
(9.) The selective mechanism comprising substantially the
combination and arrangement of parts described.

No. 21038.—26th April, 1906.—ALFRED WILLIAM BUR-
BURY, of Woodbury, Tasmania, Australia, Pastoralist. Im-
proved means for securing the strands of a wire fence to the
standards or droppers.*

Claims.—(1.) A clip, adapted to be locked upon a dropper
or standard, consisting of a piece of sheet-metal bent medially
to form a ridge in which a hole is bored horizontally
and an incision made about opposite to and obliquely with
such hole, as and for the purpose specified. (2.) The com-
bination with clips of the character described in claim 1
of the droppers and standards in a fence, the strands of which
are held in the clips which are lockable at any point with the
droppers or standards, as specified. (3.) The combination
in a wire fence with the droppers and standards, of clips
of the character indicated in claim 1, and additional clips,
having parallel or right-angled incisions for the top and bot-
tom strands of the fence, and a tapered pin for locking the
strands in said additional clips, as described. (4.) The modi-
fied form of clip, consisting of a filleted piece of sheet-metal
bent at its middle part into a ridge, and adapted to be locked
upon a fencing-dropper or standard, substantially as described
and as illustrated. (5.) The special tool for putting on or
taking off the clips, characterized by two parts pivotally
attached, the one part having a slotted claw and the other
a pair of horns or short arms, as specified and operating in
the manner explained.

No. 21175.—21st May, 1906.—EMIL DEISTER, of 1415
Webster Street, Fort Wayne, Allen, Indiana, United States
of America, Mechanic. Ore-concentrators.

Extract from Specification.—This invention relates to ore-
concentrators of the class which comprise a shaking or recipro-
cating table having riffles across its face and over which the
ore is washed, so that the heavier particles are separated from
the lighter, and collected at different points. The invention
consists in improvements in this class of concentrator, and the
object thereof is to effect the removal of mineral from the
concentrating table as rapidly as the same becomes clean,
and this is done by providing local washing surfaces adjacent
the mineral discharge side of the table, and suitably supplying
the same with dressing water; and also by the particular
form of the concentrating table.

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

No. 21207.—1st June, 1906.—JOHN ALBERT FERGUSON,
of 811 Seventeenth Street, Denver, Colorado, United States
of America, Manufacturer (assignee of George Patchett
White, of Wallace, Shoshone, Idaho, United States of America,
Manufacturer). A moulding-machine for building-blocks.

Extract from Specification.—The objects of my invention are
to provide a moulding-machine which will apply the pressure
to the material in the mould in a degree commensurate with
the depth or thickness of the material to be compressed;
also to provide a moulding-machine constructed so that the
operator can produce the moulded articles with maximum
speed and convenience, and one which will enable him to
remove the moulded product from the machine in a ready and
expeditious manner; also one which can be actuated by any
suitable power, either by hand-levers or by any power con-
trivance adapted for imparting an oscillating movement to
the principal crank-shaft controlling the operative means of
the machine; and also one in which the toggle mechanism is
compounded in such a manner that the machine can be
“set” ready to receive the heavy pressure adapted to
sufficiently compress the material in the mould without the
long oscillating stroke which is usually employed in machines
of this character.

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

No. 21666.—18th August, 1906.—ARTHUR JOSEPH HALL,
of Strathmore, Thornleigh, Sydney, New South Wales,
Australia, Orchardist. Improved appliances for feeding
brushes with pigment.

Claim.—In combination, a brush, a handle attached to
the top of the brush, a reservoir carried by the handle, a
regulating spindle supported axially within the reservoir,
a tube through the wooden top of the brush, and means for
depressing the spindle so that the flow of liquid from the
reservoir to the bristles of the brush may be regulated or
stopped, as set forth.

No. 21769.—26th March, 1906.—JOHN WILLS CLOUD, of
82 York Road, King’s Cross, London, England, Engineer.
Improvements in automatic compressed-air brake apparatus
for railway and other vehicles.

[NOTE.—This is an application under Section 106 of the Act, the date
given being the official date of the application in Great Britain.]

Claims.—(1.) In a triple valve for a compressed-air brake,
means whereby the rate of flow from the source of supply to
the brake-cylinder is automatically governed in accordance
with variations in brake-cylinder pressure, substantially as
and for the purposes set forth. (2.) For a compressed-air
brake a triple valve in which the rate of flow of air to the
brake-cylinder from the source of supply is confined between
maximum and minimum limits, and a valve operated by varia-
tions in the pressure of air in the brake-cylinder is provided
for regulating the rate of flow within said limits, substantially
as and for the purpose specified. (3.) A triple valve having
a passage leading from the brake-cylinder to the exhaust
separate from that by which air is supplied to the brake-
cylinder for the purpose specified. (4.) Triple valves con-
structed substantially as described and shown in the drawings.
