COMPLETE SPECIFICATION filed by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition
and Declaration, on the 4th April, 1872, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM :
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.

page_text: DRAINAGE AND OTHER PURPOSES," and have petitioned Her Majesty to
grant unto me, my executors, administrators, and assigns, Her Royal
Letters Patent for the same, and have made solemn Declaration that
it has been communicated to me from abroad by Henry Carter, of Aylmer,
Ontario, Canada.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention,
and in what manner the same is to be performed, in and by the following
statement, reference being had to the accompanying Drawing forming
a part of this Specification :-
The purpose of this Invention is to cut trenches or ditches in which
to lay drainage tiles or for other uses, and to carry the said Invention
into effect I use a plough having attached thereto a revolving elevator
whereby the loose soil thrown up by the plough is conveyed out of the
trench and deposited along the side thereof.
· Figure 1 is a view of one side of the said implement or machine;
Figure 2 is a view of the opposite side of the same; Figure 3 is a front
view Figure 4 is a view of the rear end; Figure 5 is a plan or top
view; and Figure 6 is a view of the under side of the said machine.
Like letters indicate the same parts throughout the Drawing..
A represents the plough on the land side thereof, B the point, C the
mould board, D the coulter, Ẹ the beam, F the handles, all of which are
firmly connected to one end of the iron frame G, extending across the
top of the machine and curving downwards and under the same, as shown
in Figure 4. To the extremity of the curved end of the said frame is
attached a wheel H, upon which the outer side of the machine is
supported and carried. From the centre of the frame is hung an
elevator I, consisting of a broad circular ring J, provided on its inner
edge with a deep flange A², enclosing the arms B' attached thereto, and
whereby the elevator is suspended from the frame. Within the compass
of the flange A¹ and to the arms B¹ is secured a toothed wheel C³, which
is made to engage a pinion a, secured to the shaft of the wheel H,
whereby it is operated as and for a purpose presently shown.

page_text: It will be observed that the outer edge of the ring J of the elevator
fits closely into the mould board side of the plough, the two being
respectively curved for their mutual adaptation, as shown in Figure 5,-
and that from the end of the mould board proceeds a guard D', which
reaches around nearly to the frame, the use of which will herein-after be
shown.
E' is the pole to which the team is attached for drawing the machine.
The said pole is connected to the machine by a cross piece F", having a
slot in which the end of the pole may be adjusted in either direction.
from the middle, as the draught of the machine may require. The cross
piece F is connected to the arms G¹ by ears c, having holes therein;
whereby it is bolted to the ears d of the arms; corresponding holes being.
provided for the admission of the bolt f, by which means the cross-piece
and pole can be adjusted vertically as the working of the machine may
demand.
.
The practical operation of the above described machine is as follows:-
The machine is placed on the ground in the position shown in Figure 3,
with the plough A on the line in which the trench is to be cut. The
driver takes his place on the seat H¹ resting his feet on the step Iч. As
the machine moves forward the plough turns up the soil and throws it
upon the elevator I, which on being made to rotate by the wheel and
pinion H, a, is thereby carried up in the direction of the arrows, Figure 5,
and thrown upon the ground along the side of the trench.. The guard
D' prevents the tool from falling in the rear of the machine, and the
flange A' restrains it from falling into the machine, whereas the guard I'
prevents it from being conveyed down to the plough.
The first cut or furrow having been made, a second one is then turned
in like manner by the plough going through the furrow again, and so
on until the required depth of the trench is obtained. In consequence
of the inclined position of the machine the trench cut will be of a v
shape, so that the tiles when laid therein will have firm and solid walls
of earth against which to lie, and they can be laid without requiring
special care to have them in line; as each tile will assume a straight
direction in consequence of the angle of the trench.
The above described machine though chiefly intended for trenching for

page_text: Having thus fully described the said Invention as communicated to
me by my foreign correspondent, and the manner of performing the same,
I wish it understood that I claim,―
First. The revolving elevator I, constructed and arranged in relation
to and in combination with the plough A to co-operate conjointly 5
therewith, substantially as described and for the purpose specified.
Second. The revolving elevator I and cog wheel C³, arranged in com-
bination with the pinion a and wheel H, substantially in the manner and
for the purpose set forth.
Third. The arrangement and combination of the plough A, frame G, 1
revolving elevator I, cog wheel C', pinion a, and wheel H, substantially
as described and for the purpose specified.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and seal, this Fourth day of April, in
the year of our Lord One thousand eight hundred and seventy- 1
