IMPROVEMENTS IN WATER CLOSET APPARATUS
Year: 1884

page_text: WO SAMUEL BENJAMIN GOSLIN Founder and Engineer and JAMES JOHN BROWN
Foreman Brass Finisher both of The Crescent Foundry Cripplegate London do
hereby declare the nature of our Invention for "IMPROVEMENTS IN WATER CLOSET
APPARATUS and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:—
,,
This Invention has for its object improvements in water closet apparatus.
The basin has a lateral outlet into a vertical trunk at the lower end of which
is the closet valvo. The trunk is closed at the top by a cover and the overflow
from the basin is by an aperture or apertures in the side of this trunk opening
into a descending exterior passage. In this passage are overlapping partitions
constituting a trap to the overflow.
In the foot of the closet basin on its under side there are three apertures one
the main outlet from the basin, another corresponding to the overflow and a third
a ventilating passage for the chamber between the water in the main trap and the
valve closing the bottom of the basin. This basin is supported upon the main
trap of the closet which is fixed by its flanges to the floor. In the upper flange of
the main trap there are also three apertures corresponding to those in the foot of
the basin as stated above.
The basin with its appendages is of earthenware and so is also the closet trap
(the trap however may be of lead or other metal). Between these two pieces of
earthenware a brass plate or casting is interpose 1; it is suitably fashioned to form
the seat for the valve and it also carries the bearing and stuffing box for the valve
spindle. The valve spindle is turned from the exterior by the usual lever arrange-
ments and within the trap there is an arm on the spindle carrying a disc faced
with india rubber which closes upwards against the seating.
In order that the said Invention may be most fully understood and readily
carried into effect we will proceed to describe the Drawings hereunto annexod.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a sectional elevation of water closet apparatus constructed in
accordance with the Invention.
Figure 2 is an end elevation of the same.
Figure 3 is a portion of a back clevation and

page_text: a is the basin, al is the vertical trunk forming a part of the same it gives ready
access to the valve and seating. a' is the main outlet from the pan at the lower
end of the trunk a'. a. a. are the orifices by which the overflow from the pan
is led away. a is the passage by the side of the trunk a¹ which receives the
overflow ax and a*** are partitions in the passage a constituting a trap therein.
a is the ventilating channel, it terminates at the top in an orifice ax from which a
pipe is led to the open air. bis the main trap it is fixed to the floor by its
flanges b¹ and has its outlet at 62 where it is connected with the drain. At the top
of the trap 6 are separate passages corresponding to the main outlet a' from the
basin and to the overflow and ventilating passages at and a³.
c is the brass or metal plate or casting which is interposed between the foot of
the basin a and the top of the trap b and which is shut in between the flanges of
these parts. c is a circular lip on the plato c forming the valve seat. c² is the
stuffing box and bearing for the valve spindle; the trap bis recessed at the top to
receive these parts and a sound joint is made with cement. The plate chas
apertures through it corresponding to a². a. and a³. № is the valve spindle, the
mechanism by which it is moved is of the ordinary description. d' is an arm on
the spindle, d² a disc which the arm carries and which forins the valve and d³ is
an india rubber facing secured upon the upper surface of the disc d².
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is:-
First. The basin with its side trunk trapped overflow and ventilating passage
formed substantially as described.
Second. Providing within the flanges of and between the basin and trap in
addition to the main passage or outlet another passage or passages for the overflow
or for a ventilating channel substantially as described.
Third. Interposing between the flange forming the foot of the basin and the
corresponding flange or surface at the top of the trap a metal plate or casting
having thereon the valve seat and the stuffing box and bearing for the valve
spindle substantially as described.
Fourth. The construction of water closet apparatus substantially as herein
described and illustrated by the annexed Drawings.
