No. 24283.-21st April, 1908.-WILLIAM GEORGE LANDELLS,
of Service Street, Coburg, Victoria, Australia, Carpenter.
Improved self-heating adjustable cattle-branding appliance.

Claim.—In an appliance of the character described, the
combination of the adjustable guard-frame having its inner-
end sleeve (4) formed into a clamp (5), with the removable
tubular frame having thereon the several cut or marked
divisions of an inch, whereby the said adjustable guard-
frame can be set so as to allow of the letters or numerals of
the branding-plates projecting beyond the outer face or
plane of the guard (3) in order to suit the required depth of
burn, as and for the purpose described.

[Note.—Here follow four other claims.]

No. 24347.-13th July, 1908.-JAMES WILLIAM FAULKNER,
of Castle Street, Dunedin, New Zealand, Wire-worker and
Bedstead-maker. Flexible fireproof-wire cloth.

Claim.—In wirewove-sheeting, the gathering and inter-
twining or interlocking at intervals of the usual plain spirals
so as to form diagonal ribs at regular distances, all substantially
as set forth, and as shown on the drawing. In wirewove-
sheeting, ribs containing air, thus rendering the material
fireproof, all substantially as set forth.

No. 24393.-MAURICE GEORGE NEWBOULD, of Coote Road,
Napier, New Zealand, Electrician. An improved automatic
cut-off for alternating-current conductors.*

Claims.—(1.) For the purpose indicated, the employment
of induction apparatuses, one for each insulated section of an
electrical conductor, the respective coils in which current
is induced being in electrical connection through a wire in
which is located the solenoid of a trip arrangement, said
trip arrangement normally retaining a circuit-breaker in such
position that electrical communication is established between
insulated sections of the conductor to which said induction
apparatuses are severally connected, the current in the
induction apparatuses being under normal conditions equal,
whereby one balances the other, substantially as specified.
(2.) Apparatus for carrying the invention indicated into effect,
consisting of the parts constructed, arranged, combined, and
operating, substantially as described and illustrated. (3.) In
apparatus for the purpose indicated, the combination of the
current-breaker and the solenoid trip arrangement for re-
leasing same, substantially as specified and illustrated.

No. 24447.-27th May, 1908.-GEORGE CLARK RICHARDS,
of 1417 Ashby Avenue, City of Berkeley, County of Alameda,
State of California, United States of America, Mining Engi-
neer. Fume-condensing apparatus.

Claim.—An apparatus for condensing vapours, said appa-
ratus having in combination a smoke-stack, a pipe extension
of the stack, said extension being arranged at an angle to the
stack, and having a bend at one portion connecting with the
stack, and having a bend in its opposite portion, a tank
fixed below said second bend, said bend adapted to deliver
into said tank, and a hydraulic jet arranged in the pipe-ex-
tension and discharging in advance of the first-named bend of
the extension and in the direction of travel of the fumes, said
first-named bend being provided with heat-resisting means
adapted to protect the bend from the intense heat induced by
the jet.

No. 24494.-2nd June, 1908.-IRVING BELL SMITH, of 1011
Diamond Street, Philadelphia, Pennsylvania, United States
of America, Electrical Engineer. Improvements in electric
self-playing musical instruments.

Extract from Specification.—My present invention relates to
automatic musical-instrument players of that type wherein
the sound-producing devices of the musical instrument
(such, for instance, as the hammers of a piano) are operated
by electro-magnetically controlled actuating-devices in-

fluenced by and responsive to the note-perforations in a
perforated music-sheet. The present improvements have
been designed primarily as an “attachment” to be applied
to the known makes of Upright Pianos without in any way
altering the usual construction of such instruments, and
without interfering with free manual or hand-playing thereof;
although I do not wish to be understood as limiting myself
specifically to what might in a limited way be termed an
“attachment,” as it will be obvious that the playing-me-
chanism herein shown and described may be so associated with
and installed in a piano during the manufacture of the latter
as to constitute and form a part thereof, as distinguished from
what might otherwise be termed or classed as an attachment.
Experience resulting from a long series of costly experiments
has demonstrated that many advantages and much better
results are secured by placing the playing-mechanism or
actuating-elements for the sound-producing devices—i.e., the
hammers—in the upper part of the piano-case; but, owing to
the narrow and limited extent of the unoccupied space in this
part of the piano, it has been difficult to provide an entirely
satisfactory construction of playing-mechanism, having the
requisite strength,, compactness, and simplicity, that can
be attached within all existing makes of piano-cases without
in some instances, at least, requiring either a cutting
of the case or a reconstruction of some of the parts of the
playing-mechanism. One of the prime objects, therefore, of
the present invention is to provide a strong, compact, simple,
and efficient construction of electro-magnetically controlled
playing-mechanism that may be easily and quickly attached
to any of the ordinary makes of pianos, the several elements
of the mechanism being so constructed and arranged that no
muffling of the musical tones will result from its use, and
ample free space will be left when the mechanism is in posi-
tion for use to enable the piano to be readily tuned without
removing or shifting the position of said mechanism, which is
a desideratum of considerable importance. A further object
of the invention is to provide a novel and simple construction
of “carrier” or supporting-rail for the playing-mechanism.
In this construction the series of electro-magnets employed
to influence the operation of the piano-hammers are of the
“ironclad” type, and disposed side by side and united in
such manner that the shells thereof themselves constitute the
supporting-rail. The adoption of this type of magnet-rail
and the associated arrangement of parts not only produces
a very compact, rigid structure, but also renders possible the
use of primary batteries for furnishing the necessary con-
trolling-current, a result hitherto impractical, on account of
the large amount of current required by existing makes of
playing-mechanism. A still further object of the invention is
to provide improved manually-operable means under the
control of the performer for moving all or a [series of the
piano-hammers in the treble, middle, or bass toward and
from the piano-strings in order to secure a great variety of
variations in musical expression according to the musical
score or the individual concept of the performer, said means
operating to effect a regular gradation of the tones. A still
further object of the invention is to provide improved means
for automatically taking up the slack in the flexible connec-
tions between the actuating-elements of the player-mechanism
and the hammer-actions whereby to maintain said connections
operatively taut at all times, said means being co-operatively
associated with and operable through the same instrumentalities employed to actuate the expression-means.
