PROVISIONAL SPECIFICATION.
An Improved Inspection and Cleaning Eye on Branches and Bends,
also a New Form of Rain Water Shoe.
I, JAMES MOSCRIP 59 Marchmont Road Edinburgh Inspector of Buildings,
and Sanitary Engineer, do hereby declare the nature of this invention to be as
follows:-
The introduction of circular inspection and cleaning eyes on double and single
junctions & bends of a design to afford ready and convenient access for all cleansing
& inspection purposes. These inspection and cleaning eyes to be fitted with portable
covers, bedded down and securely fixed in an ordinary socket.
The new form of rain water shoe is intended to be placed at the foot of rain
water pipes in cases where the ordinary gulley or other trap is unsuitable and is
designed with access handhole for cleaning, and with a shallow catch pit for
intercepting broken slates, sand, leaves, and other material and at the same time to
permit in the case of clean water drains of free ventilation.

COMPLETE SPECIFICATION.
An Improved Inspection and Cleaning Eye on Branches and Bends,
also a New Form of Rain Water Shoe.
I, JAMES MOSCRIP, of No. 59 Marchmont Road in the City of Edinburgh,
Inspector of Buildings and Sanitary Engineer, 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 :-
The invention relating to improved inspection eyes or chambers on drain pipes,
has for its object the formation of chambers of a circular shape on all branches
and bends where necessary, and of a design to afford readier, and more convenient
means of access for the efficient and systematic inspection and cleansing of all
drains and branches.
For inspection purposes the head can be got in and the interior of the pipes
carefully inspected in every direction. This is of the greatest importance when
the drains are being laid, thereby avoiding the possibility of any surplus cement or
other material being left in the pipes to cause a stoppage.
Cleaning rods can be inserted with equal freedom into either the branch, or into
the straight pipe for the purpose of clearing any obstruction, or for the periodical
cleansing of the drainage system.
The inspection eyes at present in use, being formed with long narrow openings
give neither of these facilities.
The improved inspection eyes possess the advantage of being shorter, and lighter
in weight than some of those at present in use, making them easier handled, and
saving cost in transit.
They are also, owing to their compact form, very suitable in confined places,
such as in narrow courts or areas.
The channels being formed with easy curves permit the sewage to flow freely,
thus, effectively preventing the retention of solid matter at the junctions or
branches.
The covers, which can either be made in iron or in fireclay, are bedded down
with fine milled clay or other suitable material, and kept in position by galvanized
iron pins, inserted into a hole formed in the socket.

page_text: The rain water shoe, is for the purpose of placing at the foot of rain water
pipes, to give ventilation to clean water drains, in cases where the ordinary gulley,
or other form of trap, is unsuitable, or altogether unnecessary, such as in drains
for rain water only, said drain, being first disconnected from the soil drain, at or
near the junction with the latter by a proper ventilating trap.
It is designed with a catch pit in the bottom, for the purpose of intercepting
broken slates, gravel, sand, or other material, which otherwise, if allowed to pass
into the drain, would ultimately cause a stoppage.
The portable galvanized iron grating and handhole, give every facility for the
cleaning out of the catch pit.
The rain water shoe can without extra cost, be utilized for the purpose of
draining the surface water, that falls on courts or areas.
The portable grating can be replaced by a close plate when necessary,
also be formed on the sides, to receive the discharge of other pipes.

The improvements in inspection eyes on drain pipes, as well as the rain water
shoe, embraced by this invention, includes, their being made in fireclay, earthenware,
porcelain, iron, or other metal.

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 ;-
(1). A circular shaped form of inspection eye or chamber to give greater
facilities for inspecting and cleansing drains and branches.
(2). A new form of rain water shoe, with catch pit, to intercept broken slates,
gravel, or other material.
(3). The form of inspection eyes, and rain water shoes, such as herein described
and shewn in the accompanying drawings.
