No. 18971.—14th January, 1905.—JAMES RICHMOND, of
Cromwell, Otago, New Zealand, Engineer and Dredgemaster.
An improvement in gold-saving appliances.*

Extract from Specification.—The invention is an improved
apparatus for the saving of gold or other metals on dredges
and the like, and consists of a rectangular (preferably iron)
trough-like screen in which are placed perforated plates with
a series of drops of different grades. The under-side of trough
or screen is fitted with angled plates placed longitudinally in
such a manner as to convey the material to the centre of the
trough or screen and to the head of the gold-saving tables
proper. The whole apparatus is swung upon trunnions sus-
pended with connecting rods from an overhead framework,
the trough or screen is pitched to any required fall or angle
by adjusting-screws, shafts are placed on the trough or
screen, one either end, on which are secured sprocket-wheels,
and are connected by endless chains on which are attached
strong iron bars to remove any large stones that lodge on the
perforated plates and convey the same to the elevator or
after part of the dredge. A free oscillating movement is
given to the trough or screen, operated by cams or eccentrics.
The cams or eccentrics force the screen or trough in a for-
ward direction, and when it is released suddenly it returns
and strikes against a buffer of indiarubber or spring cushion,
thus by percussion the material is sent down the screen or
trough to the end of the dredge. Along either side, at a con-
venient height above the trough or screen, are placed sparge-
pipes conveying water to wash the material as it is travelling
over the perforated plates.

No. 18983.—19th January, 1905.—FRANK VICTOR RAY-
MOND, of Invercargill, New Zealand, Solicitor. Improve-
ments in spreaders for dray-chains and the like.*

Claims.—(1.) In combination, a bar having both ends
grooved, slotted caps riveted thereon, slotted metal straps
with hook-like ends attached to bar on its upper and lower
sides at both ends thereof, screw bolt to pass through the

straps adjacent to the slots in same bent down. (2.) In
combination, a bar having its ends even, slotted caps riveted
thereon, slotted metal straps with hook-like ends attached to
bar on its upper and lower sides at both ends thereof, screw
bolt to pass through the bar and the slots in straps, a nut for
use thereon, ends of straps adjacent to the slots in same bent
down. (3.) In combination, a bar having slotted caps to fit
its ends, means for fixing same, slotted metal straps with
hook-like ends attached to bar on its upper and lower sides
at both ends thereof, means to fix same to bar.

No. 19629.—26th June, 1905.—JAMES O'DOWD, of Tapanui,
Otago, New Zealand, Boardinghouse-keeper. An improve-
ment relating to roof-gutters.*

Claims.—(1.) In combination with a corrugated-iron roof
and guttering, lengths of plain galvanised iron having one
edge flanged to fit upon the moulded edge of the guttering
and nails for securing the lengths of iron to the roof, sub-
stantially as set forth. (2.) The combination and arrange-

No. 19735.—14th July, 1905.—RICHARD JOHN FRY, of
Kialla, Victoria, Australia, Labourer. An improved spring
rabbit-trap which will not hold or injure sheep when caught
therein.*

Extract from Specification.—Two protective plates are
provided, suitably hinged or supported so that when the
trap is set with the plates as a platform they will ex-
tend over the jaws. The trap has any suitable means
(as the jaws themselves) to swing the protective plates to-
wards their closed position when the jaws also approach
that position. If there is nothing between the plates
sufficiently large to arrest the movement of the plates
they will close sufficiently to permit the jaws to close
firmly on the rabbit-foot or like cause of the trap being
sprung. If, however, the cause is a sheep’s hoof or like
object, the closing of the plates is arrested in such position
that they arrest the closing of the jaws, which will not then
be so close to one another as the plates, and the hoof or the
like upon which the plates have closed will then be removable
by the animal. To support the plates in their closed or
nearly closed position there may be a horizontal wire or
equivalent projection attached to each jaw (fig. 6), and a
horizontal wire attached to the frame below each jaw may
be used as pins of the plate hinges. These hinges may be
formed by means of metal eyes or loops secured to or in-
tegral with the plates.

No. 20047.—14th September, 1905.—FRANK BLACKBURN,
of Eden Terrace, near Auckland, New Zealand, Engineer,
and JOHN ROBERTSON, of City Road, Auckland, New Zealand,
Engineer. A non-refillable bottle.

Extract from Specification.—The purpose of this invention is to provide a bottle which having been filled with the
form of fluid dealt in and afterwards once emptied cannot
again be refilled. This is accomplished by the neck of the
bottle being enlarged, two balls being placed within the
lower portion of the neck fitted with rubber or the like, and
when the bottle is once filled a centre-piece described being
placed in the top part of the neck and fixed therein by water-
glass or the like substance.

No. 20065.—21st September, 1905.—WILLIAM PRIESTLY
MACINTOSH, of 4, Johnston Street, Annandale, near Sydney,
New South Wales, Australia, Sculptor. An improved tobacco-lighter.

Claims.—(1.) In a cigar or cigarette lighter, the use of a
metal tube such as A with a serrated or jagged edge such
as D, and having therein contained a metal gauze wire disc
such as E, and a layer or layers of finely teased asbestos such
as C, substantially as described, and as illustrated in the
drawings, for the purpose set forth. (2.) In a tobacco-pipe
lighter, the use of a smokers’ pipe such as B, with a metal-
lined bowl such as F, having therein contained a metal
wire-gauze disc such as E, with an elongated spike attached thereto such as G, and a layer or layers of finely
teaed asbestos such as C, substantially as described, and
illustrated in the drawings, for the purpose set forth.

feeding-bottle in a rubber sack upon the inside surface of
which are projections from the rubber which bear upon the
bottle, as described. (2.) For the purpose indicated, the
general arrangement, construction, and combination of parts,

No. 20125.—4th October, 1905.—HARRY BENWELL STOCKS,
of “Stanton,” 124, Barlow Moor Road, Chorlton-cum-Hardy,
Manchester, Lancaster, England, Engineer. Improvements
in power hammers, and in means for operating same.

Extract from Specification.—My invention relates to power
hammers and similar percussive tools actuated by pneumatic
pressure, and to means for operating the same. With each
power hammer I use a separate air-compressor, and as an
essential novel feature of my invention I provide means
whereby the pressure obtained at each impulse of the compressor is withheld from the tool until a predetermined
pressure is attained within the tubing conducting the power
to the tool. On the pressure within the tubing being raised
above the predetermined degree a loaded valve, or a system
of loaded valves, is overcome by such excess pressure, and
conducts the air to one side or other of the reciprocating
piston or hammer. The piston or hammer of the tool is
unaffected unless and until the required predetermined pressure is exceeded, when the loaded valve or valves in the tool
