Contractor, 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 :-
This invention relates to gulley, grease or like traps and has for its object to enable
the channel pipe to be adjusted so that drainage may be carried into the trap
from any angle and also to construct a door which may readily allow of the pipes
being cleared.
In the accompanying drawings
Figure 1 is a plan of the improved trap.
Figure 2 is a vertical section on the line 2-2 of Figure 1.
Like letters indicate like parts throughout the drawings.
The shell A of the trap is constructed as usual with lip A¹ and strainer B arranged
as ordinarily. Above the strainer is placed the grid C which is carried by a dished
adjustable annulus D provided with an inlet D' for the channel pipe. This annulus D
may be moved round so as to allow drainage to enter from any side.
An inspection door E is provided to allow access being obtained to the interior of
the trap and pipes for cleansing purposes. This inspection door E comprises a
plate having a Hange E' round its lower edge adapted to fit into a groove in the
shell A which may be filled with grease so as to form an air-tight joint. In order to
securely hold the door E in position, it is provided on its upper side with a bar F
pivotted to the centre of the door by a pin F¹, which is provided with a squared
head F. By means of this head F the bar F may be rotated and its ends caused to
engage with bevelled grooves in the shell A, so that the door E may be securely
locked in position. A plate G provided with a central hole G¹, to allow of access
being obtained to the squared head F, is laid over the door E so as to form a level
surface at the top of the trap.
It will be seen that a trap thus constructed may be employed in any situation
where such devices are required, the adjustable top or annulus D obviating the
necessity of having an inlet for the channel pipe specially constructed for the position
in which the trap is to be put, while the inspection door E enables the interior
of the trap to be readily got at and also the drain to be cleansed should it at any time
become choked, while maintaining the trap air-tight.
The drain is constructed at such an angle that the ordinary cleaning rods may
be used, the arrangement of the door rendering it possible to use these without
disturbing the surroundings of the trap.
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 a gulley grease or like trap the combination with a shell of an adjustable
annulus such as D substantially as and for the purpose described.
2. In a gulley grease or like trap the combination with a shell of an inspection
door such as E arranged and operating substantially as described.
3. In a gulley grease or like trap the combination with a shell of an adjustable
annulus such as D and an inspection door such as E arranged and operating
substantially as and for the purpose described.

grease or like trap substantially as described and illustrated in the accompanying
drawings...
