the nitrate of soda or potash is impregnated or mixed
with an alcoholic solution of the nitro-carbo-hydrate, and
when the mixture has dried up the hydro-carbon is added,
substantially as described and for the purpose set forth.
(3.) A modification of the process claimed under No. 1,
therein consisting that the nitro-hydro-carbon is dissolved in
the water bath and is then incorporated in the dry mixture
of nitrate of soda or potash and nitro-carbo-hydrate to obtain
an absolutely watertight explosive, substantially as described
and for the purpose set forth.

No. 14320.—12th December, 1901.—JOHN DAGGETT
ASHBY, of the White Hart Hotel, corner of Bourke and
Spring Streets, Melbourne, Victoria, Artist. Apparatus for
use in athletic or gymnastic performances and exercises.

Claims.—(1.) In combination, an open frame, a sheet of
canvas or like material within the frame, said sheet being
connected to frame by a number of elastic rubbers, sub-
stantially as and for the purposes described. (2.) In com-
bination, an open frame as A, canvas or like sheet B within
the frame, rubbers as C secured to the sheet and having
means for securing them to the frame so as to be released at
will, substantially as and for the purposes described. (3.) In
combination, open frame A, canvas or like sheet B within

leather strengthening-strips and provided with eyelets,
rubbers as C having eyelets at either end and secured to the
sheet by bolts and nuts and to the frame by hooks, sub-

No. 14323.—12th December, 1901.—ERNST GUSTAF
SJÖSTRAND, of 1, Bergsgatan, Stockholm, Sweden, Mechanical
Engineer. Improvements in “kite” sinking-apparatus for
logs, sounding-apparatus and the like.

Claims.—(1.) Improved sinking-apparatus characterized
by a thin plate or disc k, provided at its fore part with a
thin, heavy bar, being attached to the apparatus behind the
centre of gravity, so that the apparatus when moving in the
water assumes a position in which there is pressure on the
upper side of the plate k, the weight of the bar (n) preventing
a lateral movement of the apparatus, substantially as de-
scribed. (2.) A modification of the apparatus claimed in
claim 1, in which the plate k is at the back united with a
plate t which is placed at a slight angle downwards from the
plate, so that the apparatus, by means of the suction
arising with comparatively great velocity on the one hand,
and counter-pressure on the top of the back plate t with less
speed on the other hand, is always kept at approximately
the same position in the water, substantially as described.
(3.) In an improved sinking-apparatus as set forth, a device
for increasing the traction-power, comprising one or more
preferably rectangular plates or discs u, which are provided
with bent-down edges parallel to the direction of motion for
resisting lateral movement, with an eye at the fore part for
suspending the apparatus, and with an eye z at a suitable
point for the wire q, substantially as described, and illustrated
in Figs. 6, 7, and 8 of the drawings.

No. 14325.—12th December, 1901.—LUDWIG GROTE, of
84B, East India Dock Road, Poplar, London, England,
Manager of Works. Improvements in or relating to ma-
chines for manufacturing glass bottles or the like.

Extract from Specification.—This invention relates to
machinery for the manufacture of glass bottles or the like,
which machinery is constructed without many of the com-
plications which have heretofore been considered necessary,
and which is adapted to be rapidly and economically ope-
rated. Simplicity is of great importance in such machines,
owing to the high heat of the molten glass, or “metal,” for
the product (hereinafter termed the “glass”), and the neces-
sity for using metallic moulds and appurtenances which
quickly absorb heat and are greatly affected by expansion
and contraction; also, because it is desirable to avoid as
much as possible delay for cooling the machine, in order that
work may proceed as rapidly as practicable while the glass
is in blowing condition, and so as to produce as many bottles
as possible per hour. In former patents for machines for
blowing glass bottles both the neck and parison moulds have
been shown vertically pivoted or hinged to a disc revolvable
in a vertical plane, while the finishing-mould has been shown
as separate from the machine. Now, in machines for blow-
ing glass bottles according to my present invention, the parts

of the finishing blowing-mould are also hinged to a central
vertical support of the main frame of the machine in such-
wise that said parts of the finishing-mould, without being
detached from the machine, can be swung, laid back, or
moved clear or out of the way, so as not to interfere with
either the neck-mould or parison-mould while the two latter
are in use—for instance, while the two latter are being em-
ployed as the measuring and parison mould in the known
manner. And, moreover, according to my present invention
I so arrange and mount upon the revolvable disc the parts
forming the parison-mould and the neck-mould respectively
as to permit the parts of the parison-mould to be swung
upwards when moved or laid back out of use clear of the
finishing-mould—that is to say, so that the parts of the
finishing-mould can then be clasped upon the neck-mould
or placed in position to finish the blowing of the bottle.
Also, according to the present invention I provide a hori-
zontally rotatable table, or turntable, or horizontal support,
mounted on the central vertical support in the machine in
suchwise as to be capable of being easily turned or moved
around such central vertical axis; and on or upon this turn-
table I arrange one, two, or more bottom pieces or blocks, of
any suitable shape, adapted to fit in or against and form
the bottom of the finishing-mould, and so located on the
turntable as to be adapted to come into correct position to
form the bottom of the finishing-mould when the parts of
the latter are clasped upon the neck-mould in readiness for
the final blowing operation, whereupon the bottom of the
bottle is formed or shaped on said bottom piece, which latter
is advantageously made adjustable vertically and [or] other-
wise—for instance, said bottom piece may be supported on
a screw-threaded rod passing through the aforesaid turn-
table, so that by simply revolving said bottom piece thereby
the latter will be raised or lowered relatively to the finishing-
mould. Thus it will be seen that according to the present
invention all the different moulds, or parts of the different
moulds, employed for measuring, &c., the charge, and for
blowing a glass bottle or the like, are hinged, or pivoted, or
connected to the machine; and by this arrangement many
advantages are obtained.

[NOTE.—The number and length of the claims in this case pre-
clude them from being printed, and the foregoing extract from
the descriptive part of the specification is inserted instead.]
