PROVISIONAL SPECIFICATION.
Improvements in and relating to Intercepting Traps and the like.
We, JAMES DUCKETT AND SON LIMITED of Burnley, in the County of
Lancaster, and JAMES DUCKETT of Woodleigh, Burnley aforesaid, Sanitary
Ware Manufacturers, do hereby declare the nature of this invention to be as
follows :―
This invention relates to improvements in intercepting traps and the like used in
connection with drains and manholes for same.

Hitherto there has been some difficulty in accurately setting these traps to
efficiently serve the purpose for which they are intended, because it will be mauifest
that on account of their peculiar shape, the workman is unable to definitely ascertain
(when fixing them) when they are so set, the work being usually done hap hazard.
It is well known that when not properly fixed, they are liable to fail as traps, and
noxious gases may pass through them into dwellings and outbuildings-a very
serious evil.
The object of this invention is to provide micans whereby any ordinary workman
may set these intercepting traps accurately, and without doubt as to their being at
a proper level. For this purpose, we make a clearly defined horizontal line upon
the outside of the article, drawn perfectly parallel with its base, or at least parallel
with the water level within the interior of the trap. On the outside of the trap
we also form or fix a projecting piece to serve as a support or rest for one end of
spirit level used in fixing, the other end of which rests upon the socket of the trap
or other support.
For the better guidance of the workman, we stamp upon the face of the trap the
words "Rest for spirit level," or other words to that effect.
This line and the lettering we prefer to stamp upon or sink into the articles when
they are being made and before they are put into the kiln, or they may be painted
or printed on the surface after being burnt. The projecting piece or support may
likewise be formed on the trap either before the latter is burnt, or it may afterwards
bé fixed thereto by cement or the like.

We, JAMES DUCKETT AND SON LIMITED, of Burnley, in the County of

manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-

as traps, and noxious gases may pass through them into dwellings and outbuildings-a
very serious evil.
The object of this invention is to provide means whereby any ordinary workman
may set these intercepting traps accurately, and without doubt as to their being at
a proper level.
For this purpose, we make a clearly defined horizontal line upon
the outside of the article, drawn perfectly parallel with its base, or at least parallel
with the water level within the interior of the trap. On the outside of the trap, we
also form or fix a projecting piece to serve as a support or rest for one end of
spirit level used in fixing, the other end of which rests upon the socket of the trap
or other support.
For the better guidance of the workman, we stamp upon the face of the trap the
words "Rest for spirit level" or other words to that effect.
This line and the lettering we prefer to stamp upon or sink into the articles when
they are being made and before they are put into the kiln, or they may be painted
or printed on the surface after being burnt. The projecting piece or support may
likewise be formed on the trap either before the latter is burnt, or it may after-
wards be fixed thereto by cement or the like. Or, a metal or other suitable stud
may be dovetailed into the trap, or holted thereto, to answer as a rest for one end
of level.
In the accompanying drawings,
Fig. 1 is an elevation of an intercepting trap, constructed in accordance with our
invention.
A is the horizontal line drawn, stamped, or cut upon the outside of the trap,
perfectly parallel with its base, or at least parallel with the water level within the
interior of the trap. Near this horizontal line, we also form or fix a projecting
piece or rest B for one end of the spirit level, the other end of which may rest upon
the socket of the trap, or another similar support to the rest B.
Words such as
"Rest for spirit level" may be stamped or formed upon the face of the trap or like
article when it is being made, and before it is put into the kiln, for the guidance of
the workman.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
Forming a horizontal line A upon the outside of intercepting trap or the like,
and fixing or attaching in close proximity, support or supports B. for spirit level,
substantially as and for the purpose described and illustrated.
