PROVISIONAL SPECIFICATION.
An Improved Street Gulley.
1. PERCIVAL WALTER ST. GEORGE of the City of Montreal, in the District of
Montreal and Province of Quebec, Dominion of Canada, Civil Engineer and City
Surveyor of the said City, do hereby declare the nature of this invention to be as
follows:-
My invention has reference to the gullies used to convey rain fall from the street
surface to the sewer, and has for its object to do away with the objectionable features
inherent in those built in brickwork, in which the action of frost and even of storm
waters necessitates constant repairs and impairs the efficiency of the gulley.
I propose to form the gulley of cylindrical sections of cast iron, glazed stone ware,
or other vitrified ware, recessed or shouldered at their upper ends so as to allow them
to sit upon each other and give a flush inner surface.
The lowest section or pot which receives the detritus, has a closed end and in the
section-immediately above is usually formed the first link of the sewer connection.
The intermediate cylindrical sections will vary in number and height according to
the depth of the sewer and upon the upper one is placed the cover or top, the upper
surface of which is flush with that of the side walk or pavement. In this top section
is formed on one side the opening through which the surface water passes into the
gulley..

An Improved Street Gulley.
I. PEROIVAL WALTER ST. GEORGE, of the City of Montreal, in the District of
Montreal, and Province of Quebec, Dominion of Canada, Civil Engineer and City
Surveyor of the said City, 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 has reference to an improved construction of the gullies used to
convey rainfall from the street surface to the sewer, and is intended to obviate the
objectionable features of those built up in brickwork.
It has been found practically impossible, in any place in which the winter
temperature is severe, to prevent frost from affecting the joints of such brickwork,
whether laid in cement or mortar, and even from disintegrating the material, thus
necessitating constant repairs and impairing the efficiency of the gulley. Heavy
storm waters will also produce the same effect.
t:.
I propose to forin the gulley of cylindrical sections with the ends recessod so as to
fit into each other and give a flush inner surface, these being made of cast iron,
glazed stone, or other vitrified ware or like substance. The lowest section or pot,
in which the detritus borne down by storm waters settles, is made with a closed end
flat on bottom so as to facilitate its soiting and afford a secure foundation for the
superstructure, and in the section immediately above this is usually formed the first
link of the connection with the sewer.
Upon the top of the intermediate cylindrical sections (which will vary in height or
number to correspond with the depth at which the sewer is built,) is placed the cover
or top, the upper surface of which is at a level with and forms a permanent part of
the sidewalk; at one side and at the edge of the sidewalk is the opening into which
Price fl

page_text: the surface water discharges, this being provided if desired, with one-or more bars to
prevent the ingress of large substances.
For full comprehension of the invention reference must be had to the annexed
drawings in which Figure 1 is a front view of the gulley; Figure 2 a vertical
sectional elevation of same; Figure 3. top view of cover, and Figure 4 section on
line, a, Figure 2.
Similar letters of reference indicate like parts.
A is the "pot or lowest section of the gulley, serving as a foundation for the
superstructure, formed with a stopped flat end into which falls any soil, etc. taken
down by rain..
B is the next section of the gulley in which is formed the outlet B', this being
protected by an apron B so as only to allow of the egress of the water rising up
from A.
C, C, are cylindrical sections forming the body of the gulley, and varying in number
and size according to the depth of the sewer from the surface of the street. It will be
seen that all these sections have as shown at a, b, and c, recessed or shouldered ends
in which the next sections can rest, with the exception of the top one, which is pre-
ferably formed with corner flanges to receive the cover D as shown in Figure 4.
This cover is shown more particularly in Figures 1 and 3, set so as to be level with
the side walk of which it forms an integral and permanent part, one side, the outer
one being flush with the chain stone and in this side is formed an opening through
which the surface water passes into the gulley. A bar or bars d placed across this
opening will prevent any large substance being carried into the gulley.
D' is the cover plate which may be raised and any detritus which may have settled
in the pot A may then be removed through it by long handled scoops.
In some cases it may be found desirable to interpose one of the sections
the "pot" A and the section B.
between
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
A street gulley formed of a cylindrical bottom section A, with stopped flat end:
section B with first joint of connection with sewer integral therewith cover D), flush
with chain stone and sidewalk, having side openings D and moveable plate D³ in
same, and sections CC built up from section B and carrying D, all as herein sct
forth.
