Improvements in Gully Traps or Cesspools.
I, JOHN HUTCHISON, of 106, St. Vincent Lane, Glasgow, Mason, do hereby
declare the nature of this invention to be as follows:
This invention relates to gully traps or cesspools such as are generally used
for outside drainage and it has for its object to improve their construction.
At present gully traps or cesspools are generally so made that a good deal of
the space which should be available for collecting sand, pebbles, mud, etc., is
lost owing to the fact that the arrangements for trapping the water occupy a
great deal of the space at the interior of the cesspool. My invention is mainly
designed to so construct the cesspool with its combined trapping arrangement
that the whole or nearly the whole of the interior of the cesspool is utilised for
collecting sedimentary matter.
In carrying out my invention I make the box or other cesspool, by preference,
of a round or square section and of earthenware or other suitable material.
Formed at the outside of the cesspool is a water trapping or sealing device
which may be made in the form of a syphon trap of tubular shape or as a simple
hollow or U shaped bend with two flat sides and curved bottom with a down-
wardly projecting tongue or seal.
The inlet end of the trapping or sealing device is formed under the channel
on the lip of the cesspool and the outlet which projects from the cesspool is
preferably made with a spigot end for receiving the faucet end of an adjoining
drain pipe.
The combined cesspool and trapping device, apart from the hoods and cover,
is made as one solid piece.
The cover of the cesspool has two apertures in it one small one over the
syphon inlet provided with a removable metal plate for cleaning purposes and
a second larger one provided with a grating through which the surface water
flows over the hood and into the cesspool. The overflow from the cesspool passes
over the projecting lip or tongue of the outflow channel and from thence into
the syphon and drain.
Under a modification the trapping or sealing device can be fitted at the inside
of the cesspool instead of at the outside. In this case no channel is formed
on the lip of the cesspool and the outlet of the syphon is arranged a little below
the lip of the cesspool. The inlet end or lip of the syphon is provided with a
projecting tongue as before. A lug or lugs may be made on the lip of the syphon
and be extended to the level of the cesspool lip for the purpose of diverting the
water outflow from the cesspool over the projecting tongue aforesaid.
The cesspool is not applicable for house drainage.

page_text: I, JOHN HUTCHISON, of 106, St. Vincent Lane, Glasgow, Mason, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to gully traps or cesspools such as are generally used
for outside drainage and it has for its object to improve their construction.
At present gully traps or cesspools are generally so made that a good deal of
the space which should be available for collecting sand, pebbles, mud, etc., is
lost owing to the fact that the arrangements for trapping the water occupy a
great deal of the space at the interior of the cesspool. My invention is mainly
designed to so construct the gully trap or cesspool with its combined trapping
arrangement that nearly the whole of the interior of the cesspool is utilized for
collecting sedimentary matter.
And in order that my said invention may be properly understood I have here-
unto appended two explanatory sheets of drawings, whereon,
Fig. I is a vertical section, on the line - Fig. 2, of the apparatus.
Fig. 2 is a plan view.
Fig. 3 is a vertical section on the line y, y, Fig. 2.
In carrying out my invention I make the box or other cesspool a, by preference,
of a round or square section and of earthenware or other suitable material and
I form, in one piece with it, a water trapping or sealing device
which may be
made in the form of a syphon trap of tubular shape with a curved bottom and
a downwardly projecting tongue or seal. The chief feature of the arrangement
is that the seal is constituted by a part of the side wall of the cesspool.
As will be seen one half of the trap is within the cesspool and the other half
outside of it, that is to say, the inlet end b¹ is at the inside whilst the outlet
end 62 is at the outside. The inlet end b¹ is, as shown clearly on the drawings,
at one corner of the cesspool and forms an upwardly projecting pipe part of the
wall of which is constituted by the wall of the cesspool, whilst the outlet end b²
forms a laterally projecting pipe, preferably of spigot shape, so as to fit within
the faucet end of an adjoining drain pipe. The part 63 of the wall of the cesspool
is carried downwards so as to form a seal c and is preferably tapered slightly.
The upper end of the part b¹ extends right up to the top of the cesspool where
it has a small portion 64 cut away so as to constitute the inlet to the trap. This
inlet is provided with a laterally projecting lip or tongue e over which the over-
flow water from the cesspool flows into the trap.
Any suitable form of cover may be used for the cesspool.
With this construction of cesspool or gully trap only the part 6 of the trap
takes up space within the cesspool so that almost the whole of its interior is avail-
able for collecting dirt, stones, etc.
Owing to the fact that the wall of the cesspool is made to constitute a part of
the trap the combined trap and cesspool can be manufactured very cheaply.
The cesspool or gully trap is not applicable for house drainage.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I consider novel and desire to claim is:
A combined gully trap or cesspool and trap in which the inlet end of the

page_text: trap is within the cesspool and the outlet end outside of it, the seal being
formed by a part of the wall of the cesspool, substantially as set forth.
