MONT, of “ Helmsdale,” Kingston-on-Thames, Surrey, Eng-
land. Improvements in road motor vehicles.

No. 17601.—2nd March, 1904.—GEORGE HENRY DUNLOP,
of 17, Dundas Place, South Melbourne, Victoria, Australia,
Civil Engineer. Improved method and machinery for ex-
cavating and conveying earth and other materials.

Extract from Specification.—This invention relates to an
improved method and machinery for excavating and convey-
ing earth and other materials. The method consists essen-
tially in hauling a scoop by means of a draught-line from
a tractor, and controlling it by means of a controlling-line
from an attachment at or upon the rear of the tractor,
so that earth and other materials can be filled into the scoop,
conveyed in it, and dumped from it. The machinery con-
sists essentially of a tractor, a scoop, and main hauling-line
of communication from the tractor to the scoop, and a con-
trolling-line of communication, simple or duplex, from an
attachment at or upon the rear of the tractor to the scoop,
together with operating mechanism for adjusting the position
of the scoop by tilting it forward or backward for the
varying positions necessary in the cycle of operations com-
prising filling, conveying to the dump, dumping, returning
the scoop to the place where it is again to be filled, and
setting the scoop ready for filling.
[NOTE.—The above extract from the specification is inserted in
place of the claims.]
