the surfaces of the passages of said valve-chamber and valve
through which the liquid flows consisting of a series of
smooth, easy curves, or of straight lines connected by
smooth, easy curves, no portion of which is normal to the
direction of the motion of the liquid, and the said sur-
faces of the passages at their conjunctions with the
said inlet and outlet streams being as nearly as may
be constructionally practicable parallel to the stream-
lines at those points. (4.) In combination, an elongated
bucket of the kind described, a valve-chamber and valve
therein, and an inlet and outlet thereto, the said inlet
having a gradually contracted area for flow in direction
of the bucket. (5.) In combination, a valve-chamber and
valve therein, and a guide for said valve the area of which
regulates the effective area of the valve exposed to pressure
on the discharge side thereof, substantially as described.
(6.) In combination, a valve-chamber and valve therein, a
guide for said valve and chamber having substantially
greater volume than the guide displacement, substantially
as and for the purposes described. (7.) In combination, a
valve-chamber and valve therein, and a removable valve-
seating ring in said valve-chamber with a contact face con-
forming to the curvature of the valve-chamber, and present-
ing a smooth flush surface to the stream of liquid, sub-
stantially as described. (8.) In combination, a valve-
chamber and valve therein, an inlet-pipe, a second valve-
chamber and a check valve therein, all arranged and
operating substantially as described. (9.) In combination,
an elongated bucket of the kind described, a valve chamber
and valve therein, and a second elongated bucket of the kind

Company (assignees of Harvey Feldmeier, of Little Falls
aforesaid, Engineer.) Improvements in check-controlled
liquid-delivery apparatus.

Claims.-(1.) In a check-controlled delivery apparatus,
the combination of a liquid-delivery mechanism, a check
provided with a series of ratchet-teeth, a reciprocating-pawl
adapted to engage said teeth and propel the check in one
direction, and a detent which prevents movement of the
check in the opposite direction. (2.) In a check-controlled
delivery apparatus, the combination of a liquid-delivery
mechanism, a check guide, a check provided with a series
of ratchet-teeth, a reciprocating propelling-pawl adapted to
engage the teeth of said check in the guide, and a detent
which prevents retrograde movement of the check. (3.) The
combination of a pump, a check guide, a propelling-pawl
adapted to engage the check in said guide, and a rotary
actuating-device for said pawl. (4.) The combination
of a pump, an actuating-shaft for the same, a check
guide, a propelling-pawl adapted to engage the check
in said guide, a rock-lever to which said pawl is
attached, a rotary actuating-device for said rock-lever,
and gear-wheels, whereby said actuating-device is driven
from said pump-shaft with reduced speed. (5.) In a check-
controlled delivery apparatus, the combination of a pump,
a reciprocating propelling-pawl adapted to engage the
controlling-check, a detent which prevents retrograde move-
ment of the check, a rotary device by which said pawl is
actuated, and a ratchet clutch which permits the rotation of
said actuating-device only in one direction. (6.) In a check-
controlled apparatus for delivering a flowing substance, the
combination of a supply passage, a delivery passage, a re-
turn passage, check-controlled means for directing the flow-
ing substance to the return passage or to the delivery passage,
and a pawl mechanism by which the check or similar con-
trolling-device is propelled, and which contains a recipro-
cating propelling-pawl. (7.) The combination of a pump, a
driving-shaft for same, a delivery passage, a return passage,
check-controlled means for directing the pumped liquid to
the return passage or to the delivery passage, an eccentric
driven by said shaft, a rock-lever driven by said eccentric, a
propelling-pawl attached to said lever and adapted to engage
the check, and a detent which prevents retrograde move-
ment of the check. (8.) The combination of a pump, a
driving-shaft for the same, a delivery passage, a return
passage, check-controlled means for directing the flowing
substance to the return passage or to the delivery passage, a
rotary actuating-device driven by said shaft, a pawl mechan-
ism which is driven by said actuating-device and whereby
the check or similar controlling-device is propelled, and a
ratchet clutch which permits said shaft to be rotated in only
one direction.

No. 14390.-30th December, 1901.-WALTER PECK, of
Dunedin, New Zealand, Consulting Engineer. Improvement
in gold-saving, especially for fine gold.

Claims.-(1.) In an appliance for saving the gold from
auriferous wash, the method of forcing the gold and wash
right through the body of the mercury, which is balanced

in the leg B by sufficient extra head in A, and the applica-
tion of jets of water or substances dissolved in same to assist
amalgamation, all substantially as shown and explained, and
as illustrated in the drawing. (2.) In combination, an in-
verted siphon AB, furnished with mercury balanced with a
head of water in the longer leg A, with sufficient extra head
to force the wash right through the body of the mercury,
and with means of changing the mercury and also of cleans-
ing same or assisting amalgamation with chemicals and jets
which also remove sediment, all substantially as explained
and described, and as illustrated in the drawing.
