PROVISIONAL SPECIFICATION.
Improved Discharge Pipe for Water Closets.
FREDERICK BOLUS, 47 Western Road, Hove, Brighton Private Tutor. I,
Frederick Bolus do hereby declare the nature of this invention to be as follows:-
.
1. To prevent Sewer Gas rising from the Discharge Pipes of Waterclosets.
2. It is composed of a rectangular tube 2 ft. 6 in. long, 5 in. by 4 in. made of
galvanised iron, to be inserted in the Discharge Pipe. In tube are fitted 3 valves,
10 inches apart, working on hinges, each valve (B) has a weight (C) suspended at
back to cause valve to rise.
3. A shield or guard (D) is placed over the back of each valve to keep water and
all substances off.
4. The hinges (E) are formed, in the casting, with the bottom of shield, and back
of valve, the bolt of binge passing through and piercing the sides of tube, for
support, and on which the valve turns.
5. Before the middle valve opens the top one closes, the same with the middle and
bottom.
6. A rim or ledge (A), in the casting, is placed above the front of each valve,
also round the edges of shield to make both air-tight.
7. At the top and bottom of rectangular tube are affixed cylindrical portions (F),
for connection with the discharge pipe, placed over the front of valves to give the
full force of water on the valves.

COMPLETE SPECIFICATION.
Improved Discharge Pipe for Water Closets.
1 FREDERICK BOLUS of 47, Western Road, Hove, Brighton, in the County of
Sussex, Private Tutor, 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 :-
1. That it is to prevent Sewer Gas rising from the discharge pipes of Water
Closets.
2. It is composed of a rectangular tube 2 ft. 6 in. long and 5 inches by 4 inches,
made of (galvanised) + in. iron, which is to be inserted in any vertical part of the
existing discharge pipe. In that tube are three valves (B), placed 10 inches apart,
working on hinges (E), the bolts of hinges piercing the sides of tube. The valves
will each be inch in thickness, the back part of the valve will not be flush with
the front part but will underlay it, being therefore inch below it in order to give
the hinges room to turn. The front of valve will measure 3 in. by 33 in. and the
back of valve 1 in. from the hinges, added to which 1 inch will underlay the front
of valve making for the back portion 24 in. length by 3 in. width. Each valve has
a weight suspended by a chain or wire 3 inches long, at the back, the chain or wire
working freely, in eyes or hooks, to cause the valve to close, immediately the water
bas passed.
The weights will be of oblong form 3 in. by 1 in. and
cause each valve to work properly; thus, a heavier
valve will allow those above to be shut before it opens.

page_text: 3. A shield or guard (D), 4 in. by 3 in. is placed above each valve, to keep
water off the back of valve and give it more force on the front, also to prevent any
substance lodging on the back.
. The shields are sloped at an angle of 63 degrees, from the side of tube to the
hinges of valves, to allow the valves to work at an angle of 60 degrees, when the full
force of water is applied.
4. One part of the hinge is formed on the bottom of shield and the other part on
the valve, in the casting, the two portions of hinge being connected by a brass bolt,
inch diameter, passing through to the sides for support, on small simple bearings,
or piercing the sides. The hinge turns on this bolt.
5. Before the second valve opens the first closes, and the same with the second and
third.
6. A rim or ledge (A), in the casting, is placed above the front and sides of cach
valve, also round the edges of shields to make them air-tight. The rims are inch
in width, and those above the valves are bevelled at the top edges so that any
substance would easily slide off. The rims round shields and over valves are to be
entire, in the casting, without break.
7. At the top and bottom of the rectangular tube are cylindrical pipes (F), for
connection with the existing discharge pipe. Those cylindrical portions are not
placed immediately over the middle of the rectangular tube, but over the front of
valves to give the full force of water to open them. In connecting with the existing
discharge pipe, that side is to be placed against the wall.
Each cylindrical portion, with cap or cover is to be cast in one piece, the top
cylindrical pipe extending downwards inside the cap or cover so as to be level with
the top of the rectangular tube (shewn by the broken line in the drawing), conveying
the water directly on the front of valves, but the lower cylindrical pipe is to terminate
at its junction with the cap or cover, to avoid a resting place being formed for any
substance. Both caps are to be screwed tightly on to the rectangular tube and
cemented at joinings.
The cylindrical portions for connection may be made of any length found necessary,
either 6, 9, or 12 inches.
(The Reference letters quoted above are from the Drawings left with the Pro-
visional Specification).
Having now particularly described the nature of my said invention and in what
manner the same is to be performed, I declare what I claim is,
1. That the cost will be smaller and the result more effectual than by any known
system, to obtain full exclusion of Sewer Gas from Waterclosets.
2. That it is applicable to all houses without any structural alterations, except to
substitute this "Improved discharge pipe for Waterclosets" for a similar length of
the existing discharge pipe, which can be effected by any Builder or Plumber at a
moderate cost in addition to the cost of apparatus.
3. That cold air rising in the Closet pan will be excluded as well as Sewer Gas.
4. That many Watercloset pans are of old construction and this invention will
remedy their chief defects, where adopted.
5. That where two or more Waterclosets are drained by the same discharge pipe
it will effectually serve for the whole.
