as specified in claim 2, a foraminous or perforated diaphragm
extending over and in contact with the mouth of the vessel,
and having a marginal portion turned down and held between
the external lateral surface surrounding the mouth of the
vessel and marginal flange. (4.) The combination with

No. 16930.—9th September, 1903.—SYDNEY ERNEST LOVE,
of Gre Gre Village, near St. Arnaud, Kara-Kara, Victoria,
Farmer, but temporarily residing at the Lancefield Mine,
Laverton, in the Mount Margaret Goldfields District, Western
Australia, and WILLIAM JOHN McRAE, of John Bull Creek,
via Gre Gre Village aforesaid, Farmer. Improvements in
clamps for handling metallic or other vessels.

Extract from Specification.—To apply our handle, when in
the form shown in Figs. 1 and 2, it is only necessary to strain
the lever into the position shown in Fig. 2 and then to hook
the upper catches over the top edge of the vessel. The lower
catches are then pushed under the vessel and the fastening
lever moved upwardly and past the stop J2. It then reaches
the position shown in Fig. 1, where it is locked. The two
clamps for a kerosene-tin or a bucket are applied in the same
way as the one described.

and the like.

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

Claims.—(1.) In a combined bucket and suction dredge,

flange, combined with a spherical cap, a socket-piece, and
spring, substantially as described and shown. (2.) In a
combined bucket and suction dredge, a pump arranged be-
tween the cheeks of ladder and having a suction-pipe which

each end of and immediately behind the lips of bucket,
substantially as described and as shown. (3.) In a combined
bucket and suction dredge the pump whereof lies between
the cheeks of ladder and has a breeches pipe at lower end of
its suction-pipe, a lay shaft for driving said pump, and which
shaft lies in a direct line with the upper tumbler shaft,
as and for the purpose described and as shown. (4.) A com-
bined bucket and suction dredge comprising a pontoon, a
ladder, an endless-link chain and buckets, a pump arranged
between the cheeks of ladder, a suction-pipe terminating in a
breeches pipe, the ends of which are furnished with spring-
cushioned nozzles, and a delivery-pipe connected by a tele-
scopic branch with a sieve or other gold, tin, or mineral-
saving appliance, substantially as described and shown.

No. 16933.—9th September, 1903.—The Colonial Ferro-
Concrete Syndicate, Limited, of 77, Bishopsgate Street With-
in, London, England, Engineers (assignees of Henry Foort, of
51, Charlwood Street, Pimlico, London aforesaid, Engineer).
Improvements in floors, partitions, walls, beams, joists,
pillars, and like structures in strengthened concrete.

Extract from Specification.—According to one part of the
present invention, floors, beams, joists, walls, or other
structures of armed concrete subject to bending-stress are
provided with stiffening bars or members disposed in the
concrete at and near the points of support in the region
which is subjected to the tensile stress above referred to—
that is to say, near the surface which is subjected to the
load or force to be supported. These bars or members may
conveniently extend to approximately the points of contrary
flexure. They may in some cases, as will be understood
from the description hereinafter contained, extend to a
sufficient distance from the points of support to take up the
tensile stress exerted in the region of the points of support,
and be then extended towards the opposite surface of the
concrete so as to also take up the tensile stress exerted there-
on in the region of the centre of the span or interval between
the supports. In the case of floors, walls, partitions, or the
like strengthened by metal rods or bars imbedded therein
from end to end, we provide, according to our invention,
additional or supplementary rods disposed in the concrete
near the loaded surface thereof, and extending from or across
the points of support to a suitable distance therefrom, and
conveniently to approximately the point of contrary flexure.
According to another part of our invention, we employ, in
combination with strengthening rods or bars disposed in the
concrete of the structure respectively near the upper and
lower or front and rear surfaces thereof, a series of struts
and ties disposed at right angles to said surfaces, and
serving to keep the respective bars at proper relative distances,
while at the same time binding them firmly together, thus
taking up the shearing-stresses exerted in the structure. Or
instead of tying the said upper and lower strengthening rods
or bars together and strutting them apart, we may imbed the
struts in the concrete at right angles to the loaded surface,
and so dispose them that they lie at or towards their respective
ends either directly against the upper and lower stiffening-
bars or in the concrete near said bars. In the case of
floors, beams, joists, walls, or like structures subject to
bending-strain, and which are unsymmetrically strengthened
by rods or bars disposed in the concrete lengthwise thereof—
for example, when only one continuous bar is provided near
the upper or lower or front or rear surface of the concrete of
the structure, or in which two or more strengthening-bars
are arranged unsymmetrically with respect to each other so
that they do not permit of being strutted and tied as above
described—we may, with the object of taking up shearing-
stresses, employ the struts alone, these being arranged at
right angles to the loaded surface, and either taking their
bearing at one end directly against the strengthening-bar, or
disposed in the concrete in such manner that said end lies
directly against the strengthening-bar or in the concrete near
the same.

No. 16945.—10th September, 1903.—UNITED SHOE MA-
CHINERY COMPANY, of Paterson, State of New Jersey, United
States of America, a corporation duly organized under the
laws of said State of New Jersey, and having a place of busi-
ness at 205, Lincoln Street, Boston, Massachusetts, United
States of America (assignees of Erastus Edwin Winkley, of
Lynn, Essex, Massachusetts aforesaid, Mechanical Engineer,
and Frederick Lyman Alley, of 83, Clarence Street, Sydney,
New South Wales, Australia, Australasian Manager of the
said company). Improvements in or relating to lasting-
machines.

Extract from Specification.—This invention relates gene-
rally to lasting-machines, but more particularly to the type
of lasting machines which embody in their construction toe-
folding plates or wipers, by means of which the toe portion
of the upper is brought into position to be tacked to the in-
sole. When machines of this class are employed in lasting
shoes having considerable lateral swing between the toe and
the heel, the swing of a right shoe being in a direction oppo-
site that of a left shoe, it is necessary to make some relative
adjustment of the toe-lasting devices and the shoe-supporting
jack to enable said toe-lasting devices to face squarely toward
the toe end of the shoe, so that said toe-lasting devices may
properly meet and wipe the upper about the toe end of the
last, and thereafter lay the edge of said upper over on to the
insole. Originally it was customary to maintain the last-
supporting jack and the toe-lasting devices fixedly in align-
ment with each other, and to employ different sets of lasting-
plates, one set shaped to face and fit the toe end of a right
last, and the other set shaped to fit and face the toe end of a
left last. Later, however, machines were devised wherein
the same set of toe-lasting plates was employed for lasting
the toe end of either right or left lasts, this having been ac-
complished by mounting the toe-lasting plates on a movable
support, and moving or swinging the plates, relatively to the
toe end of the last, into such positions as were required to
enable such plates properly to fit and act upon the toe end of
the last of a shoe in whatever direction it faced, whether it
was a right or a left last. Our present invention provides a
different arrangement of mechanism, the relative adjustment
of the last-supporting jack and the toe-lasting devices being
accomplished by mounting the last-supporting jack to swing
transversely about a vertical axis located substantially under
the toe end of a last supported in the jack.
