PROVISIONAL SPECIFICATION.
Improvements in Excavating Scoops.
I, JOHN EDWARD BROWN The Butts Alton Hampshire Manager of Steam
Cultivating Machinery do hereby declare the nature of this invention to be as
follows:-
This invention has for its object improvements in machinery for excavating and
moving of soil, cleaning out, or forming ponds or reservoirs, and consists of an
oblong frame, covered in on the sides and back, the front and top, are open. Steel
prongs are provided, to dig into the soil and form part of the bottom. Two large
wheels on a cranked axle carry the chief weight and two smaller wheels are fixed
behind. The scoop is worked by winding engines in the following manner.
Wire ropes are coupled to the chains fixed to the frame and the machine is
drawn to any desired spot where the other engine at once winds up the rope and
turns the steel prongs into the soil, pulling forward until full, the first engine now
winds in enough rope to pull over the cranked axle by means of a lever fixed thereon.
This lever is provided with teeth into which a catch or pawl drops and so
holds the wheels forward and the steel prongs clear of the ground until the scoop
arrives at the particular spot where it is desired to deposit the soil or mud. Here
the first mentioned engine pulls the scoop over backwards, the contents are
immediately discharged, and the pawl falls out of contact with the toothed lever
thus allowing the wheels to take their proper position for carrying the steel prongs
clear of the ground again to the pond or place of excavation. The other rope is
now drawn upon and the scoop again turned over and filled in the manner above
described.

COMPLETE SPECIFICATION.
Improvements in Excavating Scoops.
I, JOHN EDWARD BROWN, of The Butts, Alton, Hampshire, Contractors Agent,
do hereby declare the nature of this invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :—
This invention has for its object improvements in machinery for excavating and
moving soil, cleaning out or forming ponds or reservoirs, such machinery being
constructed and worked as I shall describe referring to the accompanying
drawings.
Fig. 1 is a longitudinal section and Fig. 2 is a plan of an excavating scoop
according to my invention in position for excavating.
Fig. 2 shews it in condition for transporting excavated material, and
Fig. 4 shews it inverted for emptying out the material.
A bottom A, a back B and two sides C C form the body of the machine as a
trough open in front and above; and pivotted on a cranked axle D on which are
mounted two travelling wheels E E. On the axle D is fixed a segment F having
several teeth in which can engage a pawl G pivotted on the side C of the trough.
The front of the bottom A is preferably made with prongs H as shewn to cut into
the soil, and the machine is attached to two hauling drums, worked by steam or
othewise, the one in front and the other behind, by two chains K and L. Two
stops S and T fixed on the side limit the movement of the trough or body of the
De

page_text: machine relatively to the segment F and consequently to the axle D on which the
segment is fixed. Pawls P are arranged so as to form pivots engaging in the ground
for the trough as it turns over. The-machine works in the following manner:
While in the position shewn in Fig. 1. it is drawn forwards by the chain K the
prongs H penetrating the soil in front, the, displaced portion of which becomes
collected in the trough behind. When the trough is sufficiently charged, the back
chain Lis tightened causing the trough to become canted into the position shewn
in Fig. 3 in which position it is retained by the engagement of the pawl G in one
of the notches of F: in this condition the machine is drawn along by the chain K
carrying the load of soil to the place where it is to be deposited. When it reaches
this place, the front chain K is left slack and the back chain L is tightened; the
pawls P are thus made to engage themselves in the soil preventing the machine
from travelling back; but as the back chain L is pulled the machine is so far
canted back that it becomes turned over as shewn in Fig. 4 emptying its contents
on the ground. The chain K being now tightened again, and L allowed to become
slack, the machine is canted back to its travelling condition as shewn in Fig. 3 in
which condition it is moved to the place to be excavated, whereupon, the pawl G
being disengaged, the machine takes the position shewn in Fig. 1, and the operation
can be repeated.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
An excavating scoop consisting of a trough body mounted on the cranked axle
of a pair of travelling wheels, and connected by a front and hind chain to suitable
hauling apparatus, by the relative action of which it is advanced excavating, or
carrying excavated material, or it is inverted to discharge its load, substantially as
described, with reference to the accompanying drawings.
Dated this 26th day of October 1891.
