No. 20645. — 23rd January, 1906. — FRANCIS WILLIAM
PAYNE, of Dunedin, New Zealand, Consulting Engineer.
Improvement in elevator-trays for gold-saving dredges.

Claims.—(1.) In elevator-trays for the delivery of tailings,
the combination of trays secured to alternate sets of links,
only said trays so formed that they still form a continuous
line when the trays and links are in the straight part of their
run, so as not to lose any of the continuous stream of tailings
delivered from the chutes, with stops or knuckle-joints for
straightening out the alternate links and preventing the
fouling of the buckets or trays, all substantially as shown on
the drawing and as described and explained. (2.) An over-
lapping continuous chain of trays arranged to be fixed to
alternate links only, for catching a continuous stream of
tailings, said trays opening out before returning to clear
themselves of foreign substances, in combination with stops
to prevent said trays from being displaced, all substantially as
set forth and as shown on the drawing.

No. 20652.—27th January, 1906.—THOMAS BASSETT, of
Christchurch, New Zealand, Merchant. Improvements re-
lating to self-dumping hay-rakes.

Extract from Specification.—This invention is for the purpose
of relieving the tines from jar after each dump, and conse-
quently, at the same time, the horse drawing the imple-
ment. In carrying the same into effect I employ a spiral
spring, one end of which is attached to the principal or axle
angle-iron, while its other end is connected to a forward
part of the frame of the machine. The spring is arranged
to receive the weight of the tines as they return to the nor-
mal position after dumping the hay.

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

lurgist. An improved process for extracting gold from
auriferous arsenical and [or] antimonial ores.

Claim.—A process for the extraction of gold from auri-
ferous arsenical and [or] antimonial ores, consisting of
subjecting the powdered ore mixed with a reducing agent
to a special roast and subsequently to treatment by a dilute
solution of hydrochloric acid, whether specially prepared or
obtained from old chlorination solutions, or of ferric chloride,
together with the further treatment of the ore by cyanide
solution or by chlorination with or without amalgamation,
substantially as described.
