COMPLETE SPECIFICATION.
Improved Gully Trap.
I WILLIAM SHOOSMITH of 15 Ivory Place Brighton in the County of Sussex
Sanitary Inspector, 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 :-
In fixing gully traps it is necessary to place them so that the connecting drain
shall not enter the main drain at right angles thereto and for this purpose it is
necessary to use a "bend" or its equivalent between the outlet of the gully and the
end of the connecting drain if the body and grating of the gully be of the usual
square type. Moreover the outlet from the gully trap is usually short frequently
necessitating the use of a bend when the descent of the connecting drain is more or
less sudden, likewise the opening for cleansing over the nose of the gully, if any,
is round in form and therefore restricted in size.
Now the object of my present invention is to provide a gully trap of such
construction as to enable it to be placed with its outlet in direct line, with its own
connecting drain whilst it shall have a square top or grating which may be placed
in line with the street or building its side parallel therewith and at the same time
an outlet or nose of various downward pitches and having an elongated hole and
cover on top of nose for cleaning drain or for testing purposes.
In describing further my invention I shall refer to an accompanying sheet of
drawings and to the figures and reference letters thereon and on this sheet of
drawings
Figure 1 is an elevation of my gully trap,
Figure 2 a longitudinal section through trap and cover or grating and
Figure 3 a plan looking downwards on to same.
In carrying out my invention I construct a gully trap chiefly of the usual type
but having the upper part of the body or chamber A made circular and terminating
in a bell-mouthed opening, seat, cr socket B in which the loose top or grating is
seated. This top is square on plan on its upper part or grating C below which it is
made circular and tapered downwardly as at D so as to fit tightly into the mouth B of
the gully-thus the top or grating may be dropped into the mouth B and then
turned to any desired angle the lower part of the gully or body with its nose or
outlet being so placed as to be in line with the drain connecting it to the main.
order to facilitate the forming of a perfect joint I may extend the outlet or nose P
and form it as shown by the dotted lines and letters Q S elongating and turning
downwards the end thereof for this purpose and with different lengths as shown so
as to be of the P, Q, or S design.
In
In order to enable the pipe to be readily cleansed and the arm to be passed
down to remove cement, etc. after jointing I form an elongated opening E over the
nose with socket to receive an earthenware or like stopper which can be removed
or sealed at pleasure without interfering with the drain or gully.
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. In gully traps the combination of a body or chamber such as A having a
circular opening or socket such as B with a square top or grating such as C having
a circular spigot or flange such as D substantially as hereinbefore described with
reference to the accompanying drawings.
2. In gully traps the combination of a circular headed chamber having a square

page_text: grating or cover with an elongated (on plan) clearance or testing hole and a
downwardly extending spigot or outlet substantially as hereinbefore described and
as illustrated by the accompanying drawings.
