Claims.—(1.) In brushware as specified, the dividing
thereof into two parts and hinging or loosely riveting the one
to the other so that the part carrying the hair or bristle can
be folded into the handle-case part suitably shaped to receive
it for the purpose set forth, substantially as described and
illustrated. (2.) In combination, the hair or bristle part of

No. 17419.—29th December, 1903.—THE FLAMELESS GAS-
LIGHT COMPANY (LIMITED), of 32, Great St. Helen’s, London,
England (assignees of William Hooker, of 210, Portland
Road, South Norwood, London, aforesaid, Gas Engineer).
Improvements in generating combustible vapour and in
regulating the supply thereof.

Claims.—(1.) The method of generating a combustible
vapour, consisting in withdrawing the exhaust air from a
hot-air engine by a blower or like apparatus driven by the
latter, the said air being forced by the blower through a
carburetter, substantially as described. (2.) In apparatus
for generating and controlling the supply of combustible
vapour, the combination of a hot-air engine, a blower driven
by the said engine and withdrawing the exhaust air there-
from, a storage vessel or holder and a carburetter through
which the air is passed for carburation, substantially as de-
scribed. (3.) In apparatus for generating and controlling
the supply of combustible vapour, the combination of a hot
air engine, a blower driven thereby and which withdraws
the exhaust air from the said engine, a carburetter which
receives the air from the blower, and a holder for storing
the carburetted vapour, the said holder automatically con-
trolling a cock in the supply-pipe, substantially as described.
(4.) In apparatus for generating and controlling the supply
of combustible vapour, the combination of a hot-air engine,
a blower driven thereby and which withdraws the exhaust
air from the said engine, a carburetter which receives the
air from the blower, a holder for receiving the carburetted
air and a branch pipe from the blower for supplying air for
heating the carburetter, substantially as described. (5.) In
apparatus for generating and controlling the supply of com-
bustible vapour, the combination of a hot-air engine, a blower
driven thereby and which withdraws the exhaust air from
the engine, a carburetter which receives the air from the
blower, a holder in which the carburetted air is stored and
which supplies vapour to the burners and to a burner for
heating the hot-air engine, and of cocks in the supply-pipes
to the holder and to the engine burner, the said cocks being
controlled by the sliding-bell of the holder, substantially as
and for the purpose described. (6.) The improved apparatus
for generating and storing combustible vapour, consisting of
the parts constructed, arranged, and operating substantially
as described and illustrated in the drawing.

No. 17420.—29th December, 1903.—GEORGE HENRY DUN-
LOP, of 17, Dundas Place, South Melbourne, Victoria, Civil
Engineer. Improved method and machinery for excavating,
dredging, and transporting earth and other materials.

Extract from Specification.—This invention relates to an
improved method and machinery for excavating, dredging,
and transporting earth and other materials with a scoop or
scraper (hereinafter called a “scoop”) operated from a main
power-station and from an outhaul-station by ropes hauled
so that the earth and other materials may be filled into it,
transported in it, and deposited from it. In this specifica-
tion the term “forward” indicates that direction in which
the scoop is drawn when it is being filled, and the term
“backward” indicates the contrary direction; by “setting
up” is meant the operation which is the reverse of over-
turning. The scoop is drawn forward at suitable varying
angle of tilt until it is filled, is drawn away backward or
forward to the place where its contents are to be deposited,
is overturned forward or backward for depositing its con-
tents, and is set up and drawn away to the place where it
is to be filled again, all by means of the ropes. Prefer-
ably, three ropes are employed, but one of these ropes
may not be required, and the scoop may be operated by
two of the ropes under certain conditions. The scoop is
a receptacle having a closed bottom, back, and sides, and
open front and top, though sometimes the top also may be
partly or entirely closed. Of the ropes employed to operate
the scoop, one is connected at the front near the cutting-
edge (this I name the “main hauling-rope”) and two are
connected at the upper part of the scoop (these I name the
“forward-hauling rope” and the “backward-hauling rope”).
The main hauling-rope and the forward-hauling rope pass
forward from the scoop to the drums of winding machinery,
or to guide-pulleys leading to them, placed beyond the
extreme forward limit of travel of the scoop; the backward-
hauling rope passes backward from the scoop to the drum of
winding machinery, or to a guide-pulley leading to it,
placed beyond the extreme backward limit of travel of
the scoop. The ropes may be connected to the scoop by
chains or bars or by bridles or bails such as are used
with animal-drawn scoops, or with the buckets of steam
excavating-shovels, or the like, of usual construction. The
three ropes are operated from a main power-station and from
an outhaul-station. These stations are combined in one
structure or are in two separate structures, according to the
nature of the work. Usually the winding machinery for
operating the ropes is all placed on the main power-station,
and there is a guide-pulley and no winding machinery on the
outhaul-station; but there may be winding machinery on
each station—as for example, on the main power-station for
the main hauling-rope and for the forward-hauling rope, and
on the outhaul-station for the backward-hauling rope. In
order that the machinery employed in this method may be
most effective, the main hauling-rope is connected to the
scoop low down, so that the power is applied as directly as
practicable to the cutting-edge of the scoop, and the forward-
hauling rope and the backward-hauling rope are connected to
the scoop so high above the bottom that their effect when
the scoop is in its normal position for filling or when filled
will be mainly or entirely to tilt the scoop, and not to draw it
along. An arm on the scoop, while not essential, is con-
venient in this respect. The method and machinery will
now be described and illustrated as far as necessary in the
drawings as used for excavating a channel in earth. (If
necessary the earth may be loosened, as by ploughing.)
It is assumed that the main power-station is fitted with
mechanism by which the winding-drums can be rotated,
and that the stations can be moved alongside of the channel
as the work progresses.
