PROVISIONAL SPECIFICATION.
Improvements in Traps and Spigot and Faucet Drain Pipes.
I, JAMES BARCLAY of 5 Greenlaw Terrace, Paisley, in the County of Renfrew,
North Britain, Builder, do hereby declare the nature of this invention to be as
follows:
This invention which relates to improvements in traps and spigot and faucet drain
pipes, has for its object a more rapid and accurate method of laying the pipes, greater
facility in getting at and removing any obstruction in them when laid, and allowing
the same to be performed without breaking or disturbing any of the pipes.
In carrying out the object of this invention the faucet of the pipe is so constructed
that it does not form a complete circle a portion of its circumference on the top at the
faucet end being removed. This opening in the faucet at its mouth, being larger than
the remaining portion of the opening in line with it. The said opening which is of a
U shape may be called an access eye," and is large enough in a four inch diameter
pipe to enable the hand to form and clean out the joint; larger pipes having
proportionately larger openings.
፡፡
This opening (access eye) or U shaped hand-hole in the faucet end of the pipe is
covered by a suitable door or lid,-fitting into and over the U shaped hand-hole-which
when shut completes the pipe, making the interior similar to that of the pipes at
present in use. As the lid is made the same width throughout a flange which fits the
external circumference of the pipe is formed at each side and round the bottom of
the U shaped opening.
In laying drain pipes constructed according to this invention the tradesman can get
his graduated rule applied along the top of the pipes without being interrupted by
the faucets, which in ordinary pipes prevent the proper application of a straight-
edge.
The faucet of the last laid pipe should receive an even bed of cement ail round, and
the vertical part of the joint be lipped with it. After the pipe to be laid has been

page_text: pressed on the cement bed, till the inside of the contiguous pipes are flush, it is
forced "home," and the superfluous cement squeezed out of the vertical joint. When
this superfluous cement has been removed the cover is placed loosely over the hand
hole to keep the drain clean until the Inspector has examined the joint (which he can
do both by sight and touch).
A thin layer of putty or other suitable cement should be laid all round the flanges
before fixing the cover permanently into its seat. The pipes will then be perfectly
flush and hermetically scaled.
Past experience of drains laid with the ordinary pipes shews that either through an
excess or lack of cement at that portion of the joints at the bottom of the drain
forming part of the water course, and especially at bends or where a pipe has been cut,
the rough edge presents an obstructing surface which gradually accumulates an
amount of solid matter until the drain is choked. Before this obstructing matter
can be removed many pipes have frequently to be destroyed; whereas by this
invention it is only necessary to remove the cover or covers, insert an iron rod to
ascertain where the obstruction is and having found it, clear the drain and replace
the cover. The drain pipes remain perfectly undisturbed.
This handhole would also be of great service on the faucet end of traps and syphons
where the joint as at present constructed cannot be seen or cleaned. An obstruction
by imperfect jointing nullifies the operation of the best existing traps.

page_text: Improvements in Traps and Spigot and Faucet Drain Pipes.
I, JAMES BARCLAY of 5 Greenlaw Terrace, Paisley, in the County of Renfrew,
North Britain, Builder, 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 :-
My Invention which relates to Improvements in traps and spigot and faucet drain
pipes, has for its object a more rapid and accurate method of laying the pipes, greater
facility in getting at and removing any obstruction in them when laid, and allowing
the same to be performed without breaking or disturbing any of the pipes.

"
In carrying out the objects of my Invention, the faucet of the pipe is so constructed
that it does not form a complete circle, a portion on the top at the faucet end of the
pipe being formed into an access eye" or U shape, large enough in a four inch
diameter pipe to enable the hand to form and clean out the joint, larger pipes having
proportionately larger openings. The width of the opening at the faucet is 24 inches
wider than the remaining portion of the opening which gives 1 inch on either side
of the opening for the rest of the flange of the lid. This " access eye or hand-hole
of U shape in the faucet end of the pipe is covered by a door or lid of the same shape
with a flange 1 inch broad all round, the upper part of the lid being formed to the
radius of the outer part of the faucet, the inner side to the radius of the inside of the
pipe proper. This door or lid when placed in position with its flange resting on
the pipe proper, completes the circle of the faucet on the outer side, and in the
inner makes the interior of the pipe perfectly regular and cylindrical, similar to
those pipes at at present in use.
In laying drain pipes constructed according to this Invention, the tradesman can
get his graduated rule applied along the top of the pipes without being interrupted by
the faucets, which in ordinary pipes prevent the proper application of a straightedge.
The interior of the faucet of the last laid pipe should receive an evan bed of cement
all round, and the vertical part of the joint be lipped with it. After the pipe to be
laid has been pressed on the cement bed until the inside of the contiguous pipes are
flush, it is forced "home," and the superfluous cement squeezed out of the vertical
joint When this superfluous cement has been removed the cover is placed loosely over
the access eye or hand-hole to keep the drain clean until the Inspector has examined
the joint (which he can do both by sight and touch).
A thin layer of putty or putty lime or other suitable material, should be laid all
round the flange, then press the cover into its seat. The pipes will then be perfectly
flush and hermetically sealed.
Past experiences of drains laid with the ordinary pipes, shews that either through
an excess or lack of cement at that portion of the joints at the bottom of the drain
forming part of the water course, and especially at bends or where a pipe has been
cut, the rough edge presents an obstructing surface which gradually accumulates an
amount of solid matter until the drain is choked. Before this obstructing matter can
be removed many pipes have frequently to be destroyed; whereas by this invention it
is only necessary to remove a cover, insert an iron rod to ascertain where the
obstruction is and having found it, remove the cover or covers convenient to the
obstruction, clear the drain and replace the cover. The drain pipes remain preferably
undisturbed.

page_text: This handhole, or access eye would also be of great service on the faucet, end of
traps and syphons, where the joint as at present constructed cannot be seen or cleaned.
An obstruction by imperfect jointing nullifies the operation of the best existing
traps.
In order that my Invention may be properly understood, and readily carried into
effect, I will now proceed to describe the drawings hereunto annexed.
Figure 1, is a plan of the faucet portion of the improved drain pipe with the cover
-removed from the access eye or hand and sight hole.
Figure 2 is a plan of the faucet portion of the improved drain pipe with the
cover on.
Figure 3 is an end clovation of the faucet end of one of my said improved drain
pipes with the cover unattached.
Figure is an end elevation of the cover and
Figure 5, is a plan of the underside of the same.
My improvements consist in forming a hand and sight hole or access eye in the
faucet end of the pipe A, by leaving out the portion B, of the faucet C, and a narrower
Ushaped opening D, in the pipe A. The U shaped opening D, is large enough in a
four inch diameter pipe to enable the hand to form and clean out the joint. The said
access eye is covered by a door or lid provided with an inward projecting U shaped
piece E, which has its inner surface curved to the radius of the interior of the pipe A.
The outer portion F', of the cover or lid is curved to the radius of the faucet and
extends in all directions beyond the beforementioned inward projecting U shaped piece.
When the cover is placed in position over the handhole or access eye, the pro-
jecting Ushaped piece E, exactly fills up the corresponding U shaped opening D, in
the pipe A, and the outer portion F, of the lid besides completing the faucet C, covers
a part of the pipe A, at each side and round the bottom of the U shaped opening D,
which when jointed with putty or putty lime or other suitable material makes the
drain hermetically sealed, and the interior of the pipe similar to those at present in
usc. If it be desired instead of forcing the pipe into its seat as before mentioned,
some pipes can be made with as much of the faucet end removed as will permit the
spigot or connecting pipe to drop into its seat, and that a corresponding length
of car can be formed on the cover to supply and fill up the part removed from
the faucet.
It is to be understood that I do not confine myself to any particular shape or size
of hand-hole or access eye, that is, instead of the U shaped handhole hereinbefore
described it may be made rectangular or any other suitable form, nor do I confine
myself to any particular dimensions of flange, as such may vary according to the
size of pipe and hand-hole. Where the pipes are required to resist great pressure,
I form the access eye wedge shaped, the narrow end of the wedge being in line with
junction of pipes. The side edges of this opening are dovetailed, its lid and edges are
of corresponding shape and dovetail.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
My Improvements in trap and spigot and faucet drain pipes consists in forming an
access eye or hand-hole in the faucet end of such pipes, whereby the said pipes
can be laid more rapidly and accurately, and obstructions within the pipes more
easily removed, the said access eye or hand-hole being covered by a suitable lid
substantially as described with reference to the annexed drawings.
