I, SAMUEL STEVENS HELLYER, of 21, Newcastle Street, Strand, in the County of
London, Sanitary Engineer, do hereby declare the nature of my invention to
be as follows:-
-
My invention has for its object to provide a water-closet which is suitable for
use in cases where it is desired to obviate the necessity for disturbing or penetrating
the floor, for example in cases where buildings are provided with fire-proof floors
the disturbance, or penetration of which would interfere with the fire-proof
character of the floor.
According to my invention, as applied to what are known as valve-closets,
I provide a basin, or pan, which is of only such a depth as to afford room beneath it,
and between it and the floor, to accomodate the valve-box and syphon pipe or
trap for affording the requisite water seal beneath the valve. The basin, or pan,
is shaped so that, although it is only of a depth sufficient to leave the aforesaid
accomodation beneath it is capable of holding a sufficient body of water above the
valve. The outlet from the basin, or pan, is preferably arranged directly over the
descending portion of the syphon-pipe or trap so as to give a direct fall through
the valve-box and the said descending portion. The syphon-pipe, or trap, may
be made of any suitable material but is preferably made of lead (to enable a reliable
connection to be made with a lead soil pipe by means of a wiped soldered joint)
and supported by a tripod, or box-like or other support, the lead at the margin
preferably overlapping the top of the said support or being secured to a ring
overlapping the said top, and being confined between it and a Hange formed on the
exterior, or lower part, of the valve-box with the intervention of such india
rubber or other packing as may be necessary. The upper part of the said tripod,
or support, and consequently of the descending limb of the syphon pipe, or trap,
and also the part of the valve-box which enters and rests thereupon, are made
circular, so that the relative positions of the outlet end of the syphon-pipe, or trap,
and of the basin, or pan, and valve box can be adjusted to suit the position of
the soil pipe, as required, and if desired the trap and connection with the soil
pipe can he first fixed and the pan and valve box afterwards be fixed in the
requisite position with great facility. The mechanism by which the basin valve
and water supply apparatus are operated can be arranged in any suitable way as
may be most convenient, a convenient way, in many instances, being to arrange
the lever by which the basin valve is operated parallel or approximately parallel
to the lever by which the water supply apparatus is operated, and to provide one
of the levers with a pin, or projection, from its side, which pin, or projection, is
situated so as to be beneath the other lever so that when the closet handle is
pulled to operate one of the levers, the other lever is also operated by the said pin

page_text: or projection and both the basin or pan valve and the water supply apparatus are
operated, the closing being effected by weights as usual when the handle is
released.

Improvements in or connected with Water Closets.
I, SAMUEL STEVENS HELLYER, of 21, Newcastle Street, Strand, in the County of
London, 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:-
My invention has for its object to provide a water-closet of the kind known as
valve closets which is suitable for use in cases where it is desired to obviate the
necessity for disturbing, or penetrating, the floor; for example, in cases where
buildings are provided with fire-proof floors, the disturbance, or penetration of
which would interfere with the fire-proof character of the floor.
I will describe my invention with reference to the accompanying drawings
Figure 1 of which is a front elevation and Figure 2 a vertical section.
According to my invention I provide a basin, or pan, A which is of only such a
depth as to afford room beneath it, and between it and the floor, to accommodate
the valve-box B, and syphon-pipe, or trap C, for affording the requisite water
seal beneath the valve b. The basin, or pan, is shaped as shewn clearly in
Figure 2 so that, although it is only of a depth sufficient to leave the aforesaid
accommodation beneath, it is capable of holding a sufficient body of water above the
valve. The outlet from the basin, or pan, is preferably arranged directly over
the descending portion of the syphon-pipe, or trap C, so as to give a direct fall
through the valve box and the said descending portion. The syphon-pipe, or
trap, C, may be made of any suitable material but is preferably made of lead (to
enable a reliable connection to be made with a lead soil pipe by means of a wiped
soldered joint) and supported by a tripod, D, or box-like or other support, the lead
at the margin preferably overlapping the top of the said support or being secured
to a ring overlapping the said top, and being confined between it and a flange
formed on the exterior, or lower part, of the valve-box with the intervention of
such india-rubber or other packing as may be necessary. This arrangement
is shewn clearly at d Figure 2. The upper part of the said tripod, or support, D,
and consequently of the descending limb of the syphon-pipe, or trap, C, and
also the part of the valve-box B which enters and rests thereupon, are made
circular, so that the relative positions of the outlet end of the syphon-pipe, or trap,
and of the basin, or pan, and valve-box can be adjusted to suit the position of
the soil pipe, as required, and if desired the trap and connection with the soil
pipe can be first fixed and the pan A and valve-box B afterwards be fixed in the
requisite position with great facility. The mechanism by which the basin valve
and water supply apparatus are operated can be arranged in any suitable way
as may be most convenient, a convenient way, in many instances, being
to arrange the lever e, by which the basin-valve is operated, parallel,
or approximately parallel, to the lever f by which the water-supply
apparatus is operated, and to provide one of the levers with a pin, or pro-
jection, g, from its side, which pin, or projection, is situated so as to be in the path
of the other lever so that when the closet handle is pulled to operate one of the

page_text: levers, the other lever is also operated by the said pin or projection and both the
basin or pan valve and the water supply apparatus are operated, the closing being
effected by weights as usual when the handle is released.
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 claim is:
1. A valve-closet having a basin formed as described so as to accommodate
between it and the floor a valve-box and syphon-pipe or trap substantially as
hereinbefore described.
2. The general arrangement of parts constituting the valve-closet and operating
mechanism as herein before described and illustrated in the accompanying drawings.
