No. 14798.—24th April, 1902.—JEREMIAH CAMPBELL, of
Newton, Massachusetts, United States of America, Gentle-
man. An improvement in lighters or barges for handling
coal or other material.

Extract from Specification.—The invention is adapted to
be used in delivering the load of the lighter or barge in a
similar way—that is, to deliver it to other lighters, barges,
or any type of vessel, and at either side of the barge desired,
or alternately to vessels on both sides of the barge, or to
vessels separated from the barge by other vessels, or to
stations on land or wharf at either side of the barge. The
invention is further adapted to transfer material from one
point more or less removed from one side of the barge or
lighter to a point more or less removed on the other side,
and without handling or unloading on the lighter or barge.
The invention further relates to means for weighing the
material while it is being loaded or unloaded, and while in
the transferring grab, shovel, or bucket. I will now describe
the invention in connection with the drawings, wherein
Fig. 1 is a view in vertical cross-section of a barge or lighter,
and in elevation of the material-handling apparatus mounted
thereon; Fig. 2 is a view in side elevation of a portion of
the barge or lighter and of the apparatus; Fig. 3 is a view
in plan of a portion of the barge or lighter and of the
apparatus; Figs. 4 and 5 are views in detail, enlarged, repre-
senting devices for weighing material which is being trans-
ported; Figs. 6, 7, and 8 are detail views of one of the trolly-
booms, and of a trolly mounted upon it, and of means for
adjusting the trolly-actuating rope and rope-blocks, to
which reference will be hereafter made; Fig. 9 is a view
in elevation of the complete barge and handling-apparatus;
Fig. 10 is a view in plan of the parts represented in Fig. 9.
The invention comprises a vessel for transporting material,
such as a lighter or barge, having a hatch of very nearly the
length of the vessel, or of that portion which carries the
cargo, and having mounted upon its deck or other support,
upon each side of the hatch, tracks or rails upon which the
material-handling devices may be moved lengthwise the
vessel.

clude them from being printed, and the foregoing extract from the
specification is inserted instead.]

No. 14802.—28th April, 1902.—JAMES CLEGG, of 169, High
Street, Christchurch, New Zealand, Perambulator-maker.
An improvement in umbrellas and the like.*

Claims.—(1.) In an umbrella or the like, a sheet of trans-
parent material secured by cement and a rim to the cover-
ing of the umbrella, substantially as and for the purposes
set forth and illustrated. (2.) In an umbrella or the like, a
sheet of transparent material fastened by cement over a
hole in the covering of the umbrella and secured by a metal
rim and screws, substantially as and for the purposes set
forth and illustrated. (3.) The combination and arrange-
ment of parts comprising my improvement in umbrellas and
the like, substantially as and for the purposes set forth and
illustrated.

No. 14804.—29th April, 1902.—AMERICAN MINERAL-WATER
MACHINE COMPANY, a corporation duly organized and exist-
ing under the laws of the State of Rhode Island, and having
a place of business at 305-309, East 43rd Street, New York
City, New York, United States of America (assignees of
Peter Engelbrecht Malmstrom, of 305-309, East 43rd Street,
New York City aforesaid, Foreman). Improvements in ap-
paratus for making aerated beverages, and automatically
and electrically controlling the gas-pressure therein.

Extract from Specification.—The invention relates to im-
proved means for commingling liquids with gas, and it has
especial reference to an apparatus designed for the purpose
of producing aerated beverages or carbonating liquids by
mixing carbonic-acid gas with water or other liquid. The
invention also relates to improvements in an apparatus
whereby liquids and gas may be properly commingled and
immediately used, or a supply kept on hand to be used as
desired; and the further object of the invention is to pro-
vide improvements for automatically and electrically regu-
lating and controlling the mixture of the gas and liquid
through the medium of the pressure of the carbonated gas.
The invention has for its object a thorough commingling and
mixing of the liquid and the gas, whereby a less amount of
gas is required to charge the liquid than is ordinarily em-
ployed, or with the same amount of gas the liquid is charged
therewith to a greater extent, and to provide a simple and
compact process of carbonating, and with which the water
or other liquid can be carbonated at will and as wanted.
The form of the embodiment of the invention consists of an
apparatus in which there is a gas-holder and a pump, each
of which is connected to a carbonator or a receptacle to be
charged. The pump is operated by an electric motor, the
current of which is controlled by electrically operated de-
vices caused to act by a circuit-controller operated by gas
commingled with water forced into said receptacle by said
pump. In this connection a switch is used in the circuit of
the motor, and magnets are used to actuate the switch, and
a circuit for each magnet is controlled by a circuit-closer,
which is closed and opened by a device responsive to changes
in the pressure of the gas to which it is connected, the
arrangement being such that when the gas-pressure reaches
a predetermined point the circuit-controlling device will
operate the switch to close the circuit of the motor, and
when the gas-pressure rises above or falls below a certain
point the switch will be thrown to stop the motor and stop
the pumping.

No. 14807.—26th April, 1902.—EDWARD WATERS, Jun., a
member of the firm of Edward Waters and Son, Patent
Agents, of 414-418, Collins Street, Melbourne, Victoria
(nominee of C. B. Cottrell and Sons Company, a corporation
organized under the laws of the State of New Jersey, and
engaged in business at Stonington, Connecticut, and No. 41,
Park Row, New York, United States of America, Manufac-
turers of Printing-machines—the assignees of Milton Abbott
McKee, care of the said C. B. Cottrell and Sons Company).
Improvements in printing-plates, and in processes of and
matrices for preparing the same.

Extract from Specification.—In the manufacture of relief
printing-plates, such as electrotypes and stereotypes, it is not
possible to produce by the electrotype or stereotype process
a plate with a perfect face, or even with a face so nearly
perfect as that the printers may work directly therefrom,
and in consequence it is the universal practice, when fine
printing is to be done from such plates, to resort to certain
manipulations of the plate and the press technically known
as “making ready,” and which consists in “underlaying”
the plate and “overlaying” on the impression-cylinder, so as
to compensate for the irregularities of the plate and obtain
therefrom impressions of the exact character required.
This work of “underlaying” is exceedingly slow and time-
consuming, and in the case of artistic printing it requires
great skill and the employment of high-priced labour. The
main object of this invention is to dispense entirely with the
work of “making ready” by “underlaying” and “overlay-
ing.” This is accomplished by taking the plate as it comes
from the electrotyper or stereotyper and subjecting it to a
course of treatment whereby not only will all of the original
defects in the plate be corrected, but its printing-face will
be brought into such condition that the exact character of
impression desired from such plate may be obtained at once:
for example, all those portions of the plate which are to
yield heavy impressions and all those portions which are to
yield lighter impressions are so treated locally that when
the plate is put upon the press it will produce impressions
exactly in accordance with those predetermined, all of the
work being put into the plate instead of into “underlaying”
and “overlaying.”
