No. 16318.—7th May, 1903.—HENRY DURAND, of Timaru,
Canterbury, New Zealand, Gunsmith. An improved trace-
fastening.

Claim.—The novelty in this invention consists in the
manner of fixing the trace to the swingletree attachment by
one or more studs, a D-loop; and a clasp, substantially as
described and shown in the drawings.
(Specification, 1s.; drawing, 1s.)

No. 16335.—13th May, 1903.—The Honourable CHARLES
ALGERNON PARSONS, of Heaton Works, Newcastle-on-Tyne,
Northumberland, England, Engineer. Improvements in
steam-turbines.

Claims.—(1.) In fluid-pressure turbines of the De Laval
type, the method of securing a high relative velocity between
jet and bucket with reduced skin frictional losses by rotating
in opposite directions the element carrying nozzles and the
element carrying buckets or vanes against which the fluid
impinges, substantially as described. (2.) The improved
turbine of the De Laval type consisting of a single pair of
co-axial elements rotating in opposite directions, the one
element carrying nozzles and the other vanes, mid vanes
being so disposed that the working-fluid after impinging on
them passes to the exhaust without interfering with the
action of succeeding jets, substantially as described. (3.) In
turbines as claimed in claim 2, the method of reversing con-
sisting in so disposing a separate set of nozzles supplied with
the working-fluid through a separate set of passages and fed
from a separate pressure-chest, that they may direct the
fluid against the reverse side of the buckets, or a separate
row of reverse buckets, substantially as described. (4.) In
turbines as claimed in claim 2, the method of reversing con-
sisting in fixed jets causing the fluid to impinge on the
reverse side of the buckets or on separate reverse buckets,
substantially as described. (5.) The improved turbine sub-
stantially as described with reference to Fig. 1 of the draw-
ings. (6.) The improved turbine substantially as described
with reference to Fig. 2 of the drawings. (7.) In turbines as
claimed in claim 2, the improved means for reversing sub-
stantially as described with reference to Figs. 6 and 7 of the
drawings. (8.) In turbines as claimed in claim 2, the im-
proved means for reversing substantially as described with
reference to Fig. 8 of the drawings. (9.) In turbines as
claimed in claim 2, the improved means for reversing sub-
stantially as described with reference to Fig. 9 of the

Claims.—(1.) A method of producing bricks or blocks of
sand, lime, and the like by pressing in moulds, characterized

nary top pressure by means of a wedge-shaped plunger, and
to a final bottom pressure against a stationary press-head,
whereby a sharp-edged brick is obtained of great density on
both its faces. (3.) The combination of the ratchet table-
r otating gear with the toggle-operating gear in such a man-
ner that the table is mused to revolve with the weight of the
