Improvements in Water Closets.
I, WALTER BROWN HARVEY DRAYSON, of the firm of I. Tylor & Sons, of 2
Newgate Street, in the City of London, Brassfounders, do hereby declare the nature
of the said invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement, reference
being had to the accompanying sheet of drawings, and to the letters and Figures,
marked thereon, that is to say:-
This invention relates to that kind of water closet the basin of which is formed
with an apron, skirt, or shield in front, which usually extends more or less round the
sides, and which supports the weight of the basin and of the person using the closet...
Heretofore, so far as I am aware, it has been customary to mould the earthenware
basin and trap in one piece, the outlet end of trap being usually connected to the soil
pipe by a putty or cement joint. This putty or cement joint is thus situated on the-
soil pipe side of the trap, so that in the event of such joint being imperfectly made or
becoming broken from any cause, the sewer gases can escape from the soil pipe direct..
into the room containing the closet, the trap being useless to prevent such escape.
Now the object of my invention is to obviate this defective construction, and for this
purpose I construct the trap separate and distinct from the closet basin and preferably
of lead or other suitable metal, so that its outlet end can be soldered or otherwise
secured perfectly air-tight to the soil pipe, and I form the other end of the trap so
that the outlet of the basin can be connected to it by the putty or cement joint
preferably in the manner hereinafter more fully described. By this means the latter
joint which as before stated is liable to be imperfect, either by not being properly
made at first, or by being subsequently damaged, is situated at the inlet end of the
trap, while the outlet end of the trap is secured air tight to the soil pipe, so that
if the putty or cement joint should be imperfect, the sewer gases are still prevented
from escaping, by reason of the trap intervening between the soil pipe and the said
defective joint.
In the drawings hereto annexed Figure 1 is a longitudinal section of an apron'
closet basin with eparate trap, constructed in accordance with my invention, and
Figure 2 an enlarged view shewing the joint which I prefer to employ between the
basin and the trap. A is the closet basin constructed in one piece with the apron,
skirt, or shield B. is the trap constructed preferably of drawn lead and soldered
or otherwise connected air tight at its outlet end C¹ to the soil pipe D. The trap C
is constructed at its inlet end C2 with a socket which receives the lower end of the
basin A, the space between the basin, A and the sides of the socket being filled in
with putty or cement in the usual way. The trap C may be provided with a foot C³
for the purpose of supporting the same, but preferably arranged so that it carries no
part of the weight of the basin A, nor of the person using the closet.
Instead of jointing the basin A direct on to the trap C, I prefer to employ a ring
or socket D of brass or other suitable material, which is soldered or otherwise
permanently secured to the end C2 of the trap C. The lower part of the basin A,
which is preferably shaped as shewn at A', is placed in the socket and held therein by
screws and putty or cement as shewn.
It will be clearly seen from the drawings that the putty or cement joint at C² is
cut off from communication with the soil pipe D by the interposition of the trap C,
and that, so far as the escape of sewer gas is concerned, it is of no consequence
whether the joint at C2 remains sound or not, the escape of sewer gas from the soil
pipe being prevented by the liquid seal in the trap C, as long so the joint at (1
remains sound; and as that joint may easily be made and maintained absolutely
perfect and gas tight for an indefinite period by means of soldering as shewn, or by

page_text: flanges drawn together by bolts and nuts, or in any other suitable way, there is no
fear of such joint being broken, as there is when the joint is made of putty or
cement.
By making the trap separate from the basin, and fixing it in the manner described,
another advantage is obtained, namely, that the trap can be fixed in any desired
position, within certain limits, to suit the position of the soil pipe with reference to
the basin, so that the outlet of the trap may be placed immediately behind the basin
or more or less to one side thereof.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
-
First In a water closet, having a basin with an apron, skirt, or shield, making
the said basin without a trap, and employing in connection therewith a separate trap of
lead or other suitable metal connected to the said basin and to the soil pipe, sub-
stantially as herein before described, and illustrated in the drawings, and for the purpose
specified.
Second-In a water closet, having a basin with an apron, skirt, or shield, making
the said basin without a trap, but with its lower end adapted to be jointed to a separate
trap substantially as hereinbefore described, and illustrated in the drawings, and for
the purpose specified.
Third In a water closet, the use of a separate ring or socket, soldered or other-
wise permanently secured to the inlet end of the trap, and so adapted that the lower
part of the basin may be cemented therein, substantially as hereinbefore described,
and illustrated in the drawings hereto annexed.
