No. 24127.—12th March, 1908.—WILLIAM SILVER, of Peel
Street, Tamworth, New South Wales, Australia, Engineer.
Improvements in sheep-shearing machines.

Extract from Specification.—In carrying out my said invention I fit on the crank-pin a cylindrical slipper which works
in the bored jaw of the lever, taking the place therein of the
roller heretofore used on the crank-pin. In the case of a
four-point cutter I use a lever preferably of the later Silver
type, in which the tension is applied to a supplementary lever
riding in the main vibrating-lever in such a way that the
tension is carried by the supplementary lever directly to the
outer points of the cutter and indirectly through the main
lever to the middle points, and is so equally distributed between them, and I provide means whereby the quantum of
tension directed on to the middle tines of the cutter is distributed and equalised between them so that a uniform tension is applied to each and all of the four points.

No. 24136.—10th March, 1908.—JOHN RUTHERFORD PARK,
a member of the firm of A. J. Park and Son, of 131 Princes
Street, Dunedin, New Zealand, Registered Patent Agents
(the nominee of the Welsbach Light Company of Australasia,
Limited, of 2 Bury Street, St. Mary Axe, London, England—
the assignees of Marcel Pierre Vincent Delage, of 151 Rue de
Courcelles, Paris, French Republic, Manufacturer). Manufacture of incandescence mantles for radiating heat and the
application thereof.

Claims.—(1.) The described manufacture of a radiating
body for a gas-stove, consisting in drawing together by means
of an asbestos thread one end of a short tube cut from a long
one knitted from asbestos thread on a known machine, and
of diameter suitable for the flame of the gas-burner, providing
the end thus drawn together with a suspensory loop, then
dipping the mantle thus formed into a hardening liquid
consisting of an aqueous solution of a salt of aluminium,
magnesium, thorium, or glucinium, or of silicate of soda, or
consisting of powdered felspar or kaolin suspended in water
or in such a solution, or of a mixture of any of these in diverse
proportions, then draining or wringing the mantle, then moulding it on a wooden mould of the exact form, and then calcining
the mantle over a gas-burner, the mantle thus finished being,
if desirable, dipped into a solution of a salt of chromium or
cerium, drained and again calcined. (2.) In a gas-stove
adapted for use with radiating bodies in the form of mantles,
making the pipe that carries the burners movable so as to
facilitate the cleaning of the burners without disturbing the
radiating bodies, substantially as described. (3.) A construction such as is referred to in clause 2, wherein the ends
of the pipe extend through slots in the sides of the stove
and is maintained in operative position by two hooks adapted
to be turned to disengage the pipe so that the latter can be
slid in the slots to bring the burners, which are independent
of the refractory bodies, towards the front of the stove in such
a position that they can easily be cleaned without disturbing
the refractory bodies, substantially as described. (4.) In a
stove of the kind referred to in the preceding claims, dividing
the pipe that carries the burners into two compartments
by a longitudinal partition, and a single cock controlling
both compartments in such a manner that the burners can
be lighted or extinguished in three combinations, substantially
as described.

No. 24138.—10th March, 1908.—EJNAR ALEXANDER
HYTTEN, of Copenhagen, Denmark. Improvements in or
relating to telephonic apparatus.

Extract from Specification.—This invention relates to improvements in telephonic apparatus, which are used as
dictating apparatus, and the various parts are arranged in
such a manner as to make it possible to record the speech from
a telephone apparatus in one place on a telegraphone apparatus in another place. It will thus be possible for the person
dictating to control from his seat the advancement, reversal,
and stopping of the telegraphone apparatus, being able at any
time by means of a dial indicator to watch on which part of
the wire speech is recorded. He is likewise able to hear from
his seat what has been dictated both continuously and in
separate parts, and by means of a relay it is possible to bring
effacing-magnets into and out of action. The telegraphone
apparatus, which will generally be placed in a room other than
that in which the person dictating has his seat, is provided
with removable spools with steel wire, which spools can quickly
and easily be exchanged. The spools removed from the
apparatus may be placed on another telegraphone apparatus
after having been respooled, if necessary, on a special spooling-apparatus, and from this latter telegraphone apparatus,
which is provided with push-buttons for controlling the dial
indicator and telephone, the clerk who is to record the speech
may hear the same, either in separate parts or continuously
for purpose of comparison. Without departing from the
nature of the invention the said apparatus may, of course, be
somewhat modified. It is, for instance, possible to speak
directly into the apparatus from which the dictation is given
out, and the respooling on a special apparatus may be replaced
by the telegraphone apparatus being itself moved backward,
and if desired dictating may be effected by means of a telephone transmitter arranged on the apparatus itself. The
arrangements first mentioned have been proposed with a
view to saving time, the arrangement of the special telegraphone apparatus for the dictating and respooling apparatus making it possible to effect the dictation and transcription
quite independently of each other.

No. 24145.—18th March, 1908.—SHERARD OSBORN COWPER-COLES, of Grosvenor Mansions, 82 Victoria Street, Westminster, London, England, Electrometallurgist. Improvements in the manufacture of cement.

Claims.—(1.) The process of manufacturing cement consisting in subjecting a mixture of the ingredients from which
the cement is formed to the electrolysing action of an electric
current, and subsequently cooling and granulating the mass,
substantially as described. (2.) The process of manufacturing
cement consisting in fusing in a cupola or other furnace a
mixture of the ingredients from which the cement is formed,
and then in subjecting the fused mass to the action of an
electric current, whereby the temperature of the mass is
further raised, substantially as described. (3.) The process of
manufacturing cement consisting in fusing in a cupola or
other furnace a portion of the mixture of the ingredients
from which the cement is formed, and then subjecting the
fused mass to the action of an electric current, chalk or lime
necessary to complete the mixture being added when the
temperature has been increased by the said current, substantially as described. (4.) The process of manufacturing
cement consisting in subjecting a mixture of the cementmaterials in a disintegrated condition, and wetted with an
acid-solution, to the action of an electric current, for the purpose of fusing and electrolysing the mass, substantially as
described.

No. 24146.—18th March, 1908.—HENRY EDWIN MCDONALD,
of 17 Walker Street, North Sydney, New South Wales, Australia, Merchant. Improvements relating to baling-presses.

Extract from Specification.—According to my invention I
have the usual top and bottom boxes, which in the position
for filling rest on opposite sides of two standards or uprights.
To said standards are fulcrumed two levers or brackets, one
arm of each being also pivoted to opposite sides of the bottom box. The other arms, which are provided with suitable
stops, form rails to carry the top box, which is capable of being
moved along said arms with little exertion on the part of the
operator. When the top box is placed over the bottom box
the false bottom or the like is removed from the top box, and
the material compressed into the bottom box by any suitable
means.
