Improvements in Water Closets.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 improvements in water closets, and more particularly to
certain improvements upon that class of water closets which are provided with an
absolute cut off into their connections with the soil pipe, and also with an air
compression water reservoir and with a second tank reservoir for supplying the
afterwash.
In the accompanying drawings which form a part of this Specification, and in
which similar letters of reference indicate like parts throughout the several figures,
Figure 1 is a front elevation of a water closet embodying the invention; Figure 2
is a central vertical section; Figure 3 is a cross section on line 3-3 of Figure 2;
Figure 4 is a cross section on line 4-4 of Figure 2; Figure 5 is a cross section on
line 5-5 of Figure 2, and Figure 6 is a detail view of the connecting pipes.
In the drawings A represents the casing or frame and B the water closet bowl.
C represents the air compression water reservoir.
D is the drain pipe connecting the water closet bowl with the soil pipe.
E is the after wash tank, consisting preferably of a chamber formed integral with
the bowl. Openings e and e¹ through the inner wall of this after wash tank E
connect the same with the interior of the bowl B, and thus permit the contents of
the after wash tank to flow out of the same into the bowl. Guards or shields e² deflect
the water issuing from the upper series e' of these openings and thus prevents the
same from improperly splashing the bowl. The air compression water reservoir C
is connected with bowl 13 by pipe b, after wash tank E, channel formed in the
bowl B, pipe or channel in the valve chamber F, and the port f¹ in the valve
plug F. The drain pipe D and pipe b are furnished with a common plug valve
or ground cock F which, in connection with the shell F, serves to open or close
simultaneously both said pipes. The valve shell F is furnished with a flange or
plate which fits in a suitable socket 2 formed in the bowl B and the valve shell
is connected to the bowl by screws or bolts &³, a tight fit connection being formed
by suitable cement or gasket. The valve shell is also provided with a tubular
projection f which fits in the water way or channel & leading into the after wash
tank or chamber E.
G is the water supply pipe connecting at g with the pipe which leads from the
reservoir C to the valve shell F³, connection being made by a suitable three-way
coupling g. The supply pipe G is furnished with a check valve 2, so that when
the pressure in the supply pipe happens to be less than that in the air compression
reservoir C, the water will not flow backward from the air compression reservoir
into the supply pipe.
The
The ground plug valve F is provided with two ports, one f* and one f¹.
large port when the valve is turned properly forms an open communication
between the drain pipe D and the bowl B. The smaller port in the valve plug F
serves to form an open communication between the water pipe and the water
way in the bowl B leading to the after wash tank E. The valve shell F¹ has
secured thereto a plate H furnished with a bracket H' which is provided with a

page_text: steel antifriction plate and adjusting screw, by which the valve F is held or
pressed snugly into the tapering valve seat or socket in the shell F. This insures
a tight joint between the plug and shell. At the end of the valve plug F is a
projection F having a socket F³ to receive a handle F. The lower end of the
handle engages two projectious or stops ³ ³ secured to the bracket H' and which
serves to limit the extent to which the valve plug may be turned. One of these
stops is so located as to stop the valve plug in its fully opened position when the
same is turned in the direction to open the valve; and the other to stop the valve
plug in its fully closed position when it is turned in that direction.
By connecting the supply pipe G with the intermediate pipe 6 leading from the
air compression reservoir to the bowl there is secured the important result of
causing the water to flow to the bowl both from the air compression reservoir C
and from the supply G directly, thus getting the full force of both sources of supply
when the closet is in use, or the valve opened.
The valve plug F is made somewhat shorter than its shell F₁ to compensate for
wear and thus always secure a snug fit between the plug and shell. To prevent
any possible leakage, channels communicating with the waste pipe are formed in
the shell F1 and plug F. These channels are indicated in the drawings at
f* and f³.
The air compression reservoir C is located above the water closet at an elevation
of several feet, so that in addition to the expansive force of the compressed air in
the tank the hydrostatic pressure of the water due to its elevation will be utilized
to supply a sudden and ample flush of water to the bowl. If the tank C is an
open one instead of a closed tank the weight of hydrostatic pressure of the column
of water alone supplements the supply of water from the supply pipe G and affords
an ample flush of water to the bowl.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed as communicated to me by my
foreign correspondent, I declare that what I claim is :
