COMPLETE SPECIFICATION.
Improved Stopper in connection with Intercepting Traps.
I, HENRY HERBERT COLLETT of 77 Myrdle Street, Commercial Road,
London, E., 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 :-
This invention consists of an improved stopper for the cleansing arm used in
connection with intercepting traps and its object is to enable the mouth of
the cleansing arm to be readily closed and also to be readily opened when
required.
The accompanying drawings will serve to illustrate my invention. In these
drawings:-
Figure 1 is a vertical section, Figure 2 a plan and Figure 3 a front elevation of
the outer end of a cleansing arm with my improved stopper applied thereto.
Figure 4 is a side elevation of the flanged plate or disc hereinafter described and
of the revolving button for fastening it to the collar.
Figure 5 is a view on a smaller scale of the whole intercepting trap all
the parts being in section except the outer end of the cleansing arm and the
Etopper..
a is the trap and b the cleansing arm of same, this arm having near its outer end
au internal shoulder or seat c. d is a collar or ring which is placed in the mouth
of the arm b against the shoulder or seat c and secured by means of cement or the
like as seen at e. The collar d has an india rubber seating f to form a joint with
the flanged plate or disc about to be described. 9 is a plate or disc with a flange h
to bear against the said seating f. This flanged plate when in position against the
said seating closes the mouth of the cleansing arm b. The flanged plate g
fastened to the collar d by means of a revolving or turn-button i which is pivotted
is

page_text: to the centre of the plate g as shown while its ends respectively slide into or engage
with two slots k in lugs of the collar d. Near one end of the button i is an
aperture m to receive the end of a chain n which may be carried up to the top of
the man hole.
In order to close the cleansing arm b it is only necessary to fit the flanged plate g
against the seating of the collar and to turn the button i so that it engages with
the slots k. When it is required to open the cleansing arm the button must be
turned in the reverse direction and this can be effected from the top of the man
hole by pulling the chain n.
Although I have described the collar d as being made separately from the
cleansing arm and secured thereto by cement it may if desired be made in one piece
of earthenware with the cleansing arm.
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 :-
The improved stopper for the cleansing arm of intercepting traps the said stopper
being constructed substantially as herein before described.
