IMPROVEMENTS IN SOIL OR DRAIN PIPES
Year: 1884

page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co, Patent Agents,.
Southampton Buildings, London, in the County of Middlesex do hereby declare
the nature of said invention for "IMPROVEMENTS IN SOIL OR DRAIN PIPES " to be
as follows:
This invention relates to soil, waste or drain pipes.
Soil, waste, and drain pipes of houses and other buildings, as well known, are
provided with hand holes at intervals, so that the pipes may be freed or cleared of
obstructions without necessarily breaking their continuity, said hand holes being
provided with covers or lids preferably packed to prevent the escape of obnoxious.
gases or effluvia. In some cases these hand-holes consisted simply of round openings
extending directly through the side of the pipe at right angles to its length, or of a
single passage at an acute angle to the length of the pipe, or of two of said round
passages running in opposite directions and at an acute angle to the length of the
pipe, opening to the interior of the pipe, however, at or about the same part
thereof. Round hand holes entering pipes at right angles to their length obviously
would only allow the pipe to be cleaned for a very short length of the pipe from
the hand-hole in either direction-in fact, only substantially just at and about the
hole-whereas with a single round passage entering the pipe at an acute angle to
its length the pipe can be cleaned for a great length from such passage, but only in
one direction, and that in the direction of the passage. By combining two of such
angular passages the pipe at its part where said passages are located was capable of
being cleaned to a great length in opposite directions, thus doubling the advantage
of the one angular passage, as previously arranged over a round passage or hole
opening into the pipe at a right angle thereto. While with two of the said angular
passages great advantages were secured, still their attainment was attended with
the serious disadvantage that two holes or passages were required to be closed by a
cover for each, instead of one, as heretofore.
This disadvantage is overcome by the present invention which consists in
providing the pipe with a passage leading directly into the interior of the pipe
from one side thereof, which passage has communication with the pipe at its inner

than as to the width or diameter of the pipe, and has communication with the pipe
at its outer periphery in an opening which has its centre point coincident, or

inner periphery of the pipe, and also is suitably constructed for being closed by.
a cover or lid, all substantially as hereinafter described.
In carrying the said invention into practice I provide a passage through one side
of the pipe.
This passage is the hand-hole passage, and it has one opening, at the
outer periphery, and another opening at the inner periphery, of the pipe. Between
the. two openings the passage is continuous, and the centre points of the two
openings are substantially coincident with a line running at right angles to the
length of the pipe. The second opening at the inner periphery of the pipe extends
along the length and across the width of the pipe, and in the length of the pipe it
is of a greater dimension than in the width of the pipe. In width the opening is
_equal, or substantially so, to the diameter of the pipe, and in length considerably
in excess of the diameter of the pipe. The periphery or edges of the opening is
suitably shaped. The passage at the outer periphery of the pipe, as before stated,
has its centre point coincident with a right line through it and the centre point of
the second opening at the inner periphery of the pipe, and is surrounded with a face
and flange, both adapted for the reception and fastening of a cover or lid in any
suitable manner. The outer or first opening is elongated substantially as the inner
or second opening but contracted a little in length and breadth and this contraction
might be made greater, bringing the outer opening more or less to a round shape,
in lieu of an elongated or oval shape, but in any event the walls of the passage
between the outer and inner openings, continue in such lines from one to the other
as to afford no obstruction to the use of the elongated inner opening to the full
length thereof, in the cleaning of the pipe through the same. By having an elongated
opening at the inner periphery of the pipe, and a passage leading thereto which
opens to the outside of the pipe, and such passage so shaped as to offer no obstruction
to the use of the elongated inner opening to the full length thereof, it is plaiu
that a single hole has all the advantages for cleaning the pipe through it of two
oppositely-arranged angular hand-holes and without the disadvantage of two
separate and distinct holes to be covered.

page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London, in the County of Middlesex do hereby declare
"and in
the nature of my invention for "IMPROVEMENTS IN SOIL OR DRAIN PIPES
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to soil, waste, or drain pipes.
Soil, waste, and drain pipes of houses and other buildings, as well known, are
provided with hand holes at intervals, so that the pipes may be freed or cleared of
obstructions without necessarily breaking their continuity, the said hand-holes
being provided with covers or lids, preferably packed to prevent the escape of
obnoxious gases or effluvia. In some cases these hand holes consisted simply of
round openings extending directly, through the side of the pipe at right angles to
its length, or of a single passage at an acute angle to the length, of the pipe or of
two of the said round passages running in opposite directions and at an acute angle
to the length of the pipe, opening to the interior of the pipe, however, at or about
the same part thereof. Round hand-holes entering pipes at right angles to their
length obviously would only allow the pipe to be cleaned for a very short length of
the pipe from the hand-hole in either direction-in fact, only substantially just at,
and about, the hole-whereas with a single round passage entering the pipe at
an acute angle to its length the pipe can be cleaned for a great length from such
passage, but only in one direction, and that in the direction of the passage. By
combining two of such angular passages, the pipe, at its part where the said
passages are located, was capable of being cleaned to a great length in opposite
directions, thus doubling the advantage of the one angular passage, as previously
arranged, over a round passage or hole opening into the pipe at a right angle..
thereto. While with two of the said angular passages great advantages were
secured; still. their attainment was attended with the serious disadvantage that
two holes or passages were required to be closed by a cover for each, instead
of one, as heretofore.
This disadvantage is overcome by the present invention, which consists in
providing the pipe with a passage leading directly into the interior of the pipe
from one side thereof, which passage has communication with the pipe at its inner
periphery in an opening thereof which is of a greater dimension as to the length,
than as to the width or diameter of the pipe, and has communication with the pipe
at its outer periphery in an opening which has its centre point coincident, or
substantially coincident, with the centre point of the elongated opening at the
inner periphery of the pipe, and also is suitably constructed for being closed by a
cover or lid, all substantially as hereinafter described.
In the accompanying drawing..
Figure 1 is a plan view of a portion of a soil, or drain pipe, shewing the
improved band-hole passage and its cover, the latter being partially removed so as
to expose a portion of the hand-hole passage.
.
Figure 2 is a central longitudinal section on the line 2, 2 figure 1; figures 3
and 4 are cross-sections on the lines 3, 3 and, 4, 4 respectively, figure 2.
A indicates a section of a soil-pipe of the ordinary construction and B a passage
through one side of the pipe. This passage B is the hand-hole passage, and it has
an opening C at the outer periphery, and an opening E at the inner periphery of
the pipe. Between the two openings the passage B is continuous, and the centre

points of the two openings C and E are substantially coincident with a line
running at right angles to the length of the pipe. The opening E. at the inner
periphery of the pipe, extends along the length and across the width of the pipe,
and in the length of the pipe it is of a greater dimension than in the width of the
pipe as shewn by comparing the distance from a to 6 in figure 2, which is the
length of the opening, and the distance from d to f in figure 4, which is the width
of the opening. In width the opening is equal, or substantially so, to the diameter
of the pipe, and in length considerably in excess of the diameter of the pipe. The
periphery or edge g of the opening is shaped, as shewn in figure 1. The passage B
at the outer periphery C of the pipe, as before stated, has its centre point coincident
with a right line through it and the centre point of the opening E at the inner
periphery of the pipe, and, as shewn, it is surrounded with a face land flange m,
both adapted for the reception and fastening of a cover or lid Fin any suitable
manner. As shewn, the outer opening C is elongated substantially as the inner
opening E but contracted a little in length and breadth, and this contraction might
be made greater, bringing the outer opening more or less to a round shape in lieu
of an elongated or oval shape, as particularly shewn; but in any event the walls n
of the passage B between the outer and inner openings, continue in such lines from
one to the other as to afford no obstruction to the use of the elongated inner
opening E to the full length thereof, in the cleaning of the pipe through the same.
By having an elongated opening E at the inner periphery of the pipe, and a
passage leading thereto which opens to the outside of the pipe, and such passage so
shaped as to offer no obstruction to the use of the elongated inner opening E to the
full length thereof, it is plain that a single hole has all the advantages for cleaning
the pipe through it of two oppositely arranged angular hand-holes and without the
disadvantage of two separate and distinct holes to be covered.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
In a soil or drain, pipe, the passage B through its side having an elongated
opening E at the inner periphery of the pipe, and an opening C at the outer
periphery of the pipe constructed for the reception and attachment of a cover
thereto, substantially as described for the purpose specified.
