IMPROVE- MENTS IN APPARATUS FOR LAYING PIPES IN THE EARTH, AND IN THE JUNCTURE OF SUCH PIPES
Year: 1853

page_text: LETTERS PATENT to Admiral the Earl of Dundonald, of Belgrave
Road, in the County of Middlesex, for the Invention of "IMPROVE-
MENTS IN APPARATUS FOR LAYING PIPES IN THE EARTH, AND IN THE
JUNCTURE OF SUCH PIPES."
Sealed the 2nd August 1853, and dated the 1st June 1853.
COMPLETE SPECIFICATION filed by the said Admiral the Earl of
Dundonald at the Office of the Commissioners of Patents, with his
Petition and Declaration. on the 1st June 1853, pursuant to the
9th section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
ADMIRAL the EARL of DUNDONALD, of Belgrave Road, in the County of
Middlesex, do hereby declare that the nature of the said Invention of
"IMPROVEMENTS IN APPARATUS FOR LAYING PIPES IN THE EARTH, AND IN
THE JUNCTURE OF SUCH PIPES," and in what manner the same is to be
performed, to be particularly described and ascertained in and by
the following statement thereof, reference being had to the Drawing

page_text: hereunto annexed, and to the figures and letters marked thereon, that
is to say:
The apparatus consists in a carriage having a coulter or cutter for
vertically parting the earth, and an horizontal tool attached thereto
similar to that of a drain plough, whereby an aperture or channel is
formed. From the upper and foremost part of the carriage a duct or
opening descends obliquely to the tool (or in any convenient direction),
through which duct drain pipes or other pipes may be introduced and
continuously deposited in the channel or opening formed by the pro-
gressive motion of the apparatus; to facilitate which operation the
pipes are first laid in a line on the surface beneath which it is proposed
they shall be deposited; and in order to retain them in a connected
range a rope is passed through them, which I prefer to be elastic, or to
have in one or more parts an clastic connection, in order that sudden
jerks or obstacles shall not occasion injury to fragile pipes.
For the better understanding the nature of my said carriage, coulter,
and tool (which I call a pipe depositor), I annex Figures and references.
Figure 1, shews a section of the apparatus, whereof A, B, is a beam
of wood or other material intended to restrain the movement of the
machine in a line parallel to the surface; E, D, is the coulter, or cutter;
C, F, the tool; and F, F, the duct, through which the range of pipes is
continuously to descend and be deposited in the channel or aperture
F, G.
The apparatus may resemble the ordinary form of a plough, though
the beam seems preferable by reason of its greater solidity and strength;
for the same reason apparatus differing in dimensions are more suitable
than adjustments such as are applied to ordinary ploughs.
Figure 2, exhibits the nature of my Improvements in the juncture
of pipes by a concentric knob k, (formed on the straight end usual to such
pipes), whereby the juncture may move freely within the cup or circular
segment L, lubricated by a thin solution of clay, if such pipes are
preferred.
The progressive motion of the beam and the action of the coulter
may also be facilitated by the said solution, or even by water supplied
from a tank on wheels; especially if the surface of the soil is removed
in the line of progress by an antecedent plough.

in the earth as the apparatus advances.
In witness whereof, I, the said Earl of Dundonald, have hereunto
set my hand and seal this First day of June, in the year of our
Lord One thousand eight hundred and fifty-three.
Witness,
V. CARPMAEL.
DUNDONALD. (L.S.)
