to provide a downwardly flaring portion at the bottom of the
mould-cavity and constituting a mould having its greatest
dimension at its bottom, and a member constructed to form the
bottom of said cavity and apply pressure to the flesh side of the
lift engaged by it and arranged for movement into an inopera-

No. 28107.—19th July, 1910.—UNITED SHOE MACHINERY
COMPANY, of Paterson, in the State of New Jersey, United
States of America, a corporation duly organized under the
laws of said State of New Jersey, carrying on business as Shoe-
machinery Manufacturers, and having a place of business at
205 Lincoln Street, Boston, in the Commonwealth of Massa-
chusetts, in said United States of America (assignees of
Frederic Eli Bertrand, of Swampscott, Massachusetts aforesaid,
Inventor). Improvements in or relating to machines for
operating upon soles of boots and shoes.*

Claims.—(1.) For a channelling-machine provided with sole-
feeding mechanism and a sole-edge gauge, the arrangement
that, for the purpose of relieving pressure on the gauge during
successive operations of said mechanism, the latter and the
gauge are constructed and arranged to permit a relative move-
ment of the sole and gauge away from each other across the
line of feed in the operation of the machine as the shape of
the sole may require. (2.) For a channelling-machine having
a cutter and an edge-gauge both reciprocating in the direction
of feed, the provision of automatically acting means, such that
during the cutting-stroke of the cutter the said gauge and the
sole may move, for the purpose described and as required by
the shape of the sole, relatively away from one another across
the line of feed.

No. 28451.—16th September, 1910.—EDMUND SCOTT GUS-
TAVE REES, Managing Director of the Rees Roturbo Manu-
facturing Company, Limited, of Wednesfield Road, Wolver-
hampton, Stafford, England. Improvements in ejectors,
condensers, and air-pumps or compressors.

Extract from Specification.—According to the present in-
vention, a maximum entraining surface is obtained by so
subdividing the streams that they impinge on each other
to form a fanlike sheet or sheets of water, such sheets being
also at the same time and by the same means sprayed or
subdivided. These sheets of water, of which preferably there
are several converging towards each other so as to form
with the entrained gases a compound or laminated sheet,
are directed into the narrow elongated inlet or inlets of an
expanding passage or passages in which the pressure of the
water and the entrained gases is raised to the pressure of
discharge. The invention may be applied either, as shown
in Figs. 1 to 5 of the drawings, to a stationary apparatus
in which velocity is imparted to the water in suitably
directed nozzles to which the water is delivered under
pressure, or the streams of water may be produced by a
rotary apparatus as shown in Figs. 6–8, preferably a
centrifugal pump such as described by me in previous Bri-
tish and other patent specifications.

of the claims.]

No. 28724. — 11th November, 1910. — CHARLES THOMAS
SWANELL, of 30 Cuba Street, Wellington, New Zealand;
Engineer. Improvements in smoke-consuming apparatus.*

Extract from Specification.—A skeleton bridge of the de-
sired form is provided with an air-admitting opening or open-
ings in the bottom thereof. Above the skeleton bridge a
chamber or chambers is or are placed, the interior of said
chambers being in open communication with the air-ad-
mitting opening or openings in said bridge. Means are pro-
vided for admitting steam under pressure to the said cham-
ber or chambers in order to cause a forced draught of air
into the chambers, and means for regulating the same.

No. 28917.—30th December, 1909.†—LOUIS LUMIÈRE, of
262 Cours Gambetta, Lyons, France, Manufacturer. Im-
provements in acoustical instruments.

Claims.—(1.) A sound-box for talking-machines com-
prising a stationary wall, and a movable wall capable of
approaching and receding from the stationary wall, and means
so disposed between the two walls as to complete the cham-
ber of the sound-box, but allow the whole of the movable
wall to move freely in substantially unchanged form and to
any extent which may be practically required, and offer
equally little resistance to the movements of the movable
wall whatever the position of the latter with regard to the
stationary wall, so that the position and movements of the
movable wall are regulated entirely by the sound-waves or
other means through which the movable wall is reciprocated.

[NOTE.—Here follow three other claims.]

No. 28940.—6th January, 1910.†—LOUIS LUMIÈRE, of 262
Cours Gambetta, Lyons, France, Manufacturer. Improve-
ments in acoustical instruments.

Extract from Specification.—This invention relates to im-
provements in acoustical instruments, and is an extension
of my invention as described in Specification No. 28917, of
22nd day of December, 1910, in reference to the sound-boxes
of talking-machines. I now find that my invention can be
usefully applied in the construction of the sound-boxes of
acoustical instruments such as telephones, microphones,
stethoscopes, musical instruments, and in general any in-
strument used for the reception or transmission of sounds,
and consists in certain construction of sound-box for such
instrument, the details of which will be given.

No. 28963.—23rd December, 1910.—THOMAS MARTIN SANDI-
FORD, of Masterton, New Zealand, Gasfitter. Improvements
in apparatus for lighting and extinguishing gas-lamps.*

Claims.—(1.) In apparatus of the kind described, the com-
bination of an outer chamber, a gas-chamber within said
chamber, a bell top to said gas-chamber operable by the
pressure of gas within said gas-chamber, with means for
admitting or shutting off gas from said gas-chamber to the
lamp when said means are operated by the fall of said bell
top due to reduced pressure, as set forth. (2.) In apparatus
of the kind described, the combination of an outer chamber,
a gas-chamber within said outer chamber, a movable bell
top to said gas-chamber operable by increased pressure in
said gas-chamber, means for guiding and limiting the rise
of said bell top, a drum arranged in said gas-chamber, an
opening in the lower periphery of said drum communicating
with the pipe leading to the lamp, another opening in said
drum communicating with the gas-chamber, another drum
within said first drum, by-pass openings in the periphery of
said inner drum in line with the openings in the outer drum,
and means for operating the drum by the rising of the bell
top, as set forth.

No. 29086.—1st February, 1910.†—LOUIS LUMIÈRE, of 262
Cours Gambetta, Lyons, France, Manufacturer. Improve-
ments in acoustical instruments.

Claims.—(1.) A sound-box for acoustical instruments com-
prising a stationary wall, and a light and rigid movable wall,
formed of metal dished or corrugated in any suitable manner,
and capable of approaching and receding from the stationary
wall, and means so disposed between the two walls as to com-
plete the chamber of the sound-box, but allow the whole of
the movable wall to move freely in substantially unchanged
form and to any extent which may be practically required,
and offer equally little resistance to the movements of the
movable wall whatever the position of the latter with regard
to the stationary wall, so that the position and movements of
the movable wall are regulated entirely by the sound-waves
or other means through which the movable wall is reciprocated.
