TRUVIOIONAL DI MOLTIVAL
An Improved Spittoon.
I, JOHN WILLIAMS, of 113 High Street Ventnor, Isle of Wight, Ironmonger,
do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved spittoon adapted to be fitted in the floor of
a railway or other carriage steamboat or vehicle and to automatically discharge
its contents from time to time on to the ground or into a receptacle beneath.
The spittoon is a shallow funnel-shaped tray provided with, or discharging into, a
downwardly-extending outlet pipe which may either be attached to the spittoon
tray or not so that the one may revolve on, or be removable from, the other. The
lower end of this pipe is furnished either with a counterbalanced valve adapted to
be opened automatically by the weight of the superincumbent column of liquid or
with a trap for sealing it or with a revolving hood and vane for so directing the
outlet end of the discharge tube as to prevent the ingress of an up-draught.
The spittoon tray may be made of enamelled metal or of glass or earthenware
and is adapted to be fixed in an aperture in the floor, and may or may not be fitted
with a grating or cover.

COMPLETE
SPECIFICATION.
An Improved Spittoon.
I JOHN WILLIAMS, of 113, High Street, Ventnor, Isle of Wight, Ironmonger,
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 relates to an improved spittoon adapted to be fitted in the floor of
a railway or other carriage, steamboat, or vehicle, and to automatically discharge
its contents from time to time onto the ground or into a receptacle beneath.
Reference is to be had to the accompanying drawings forming part of this
Specification, wherein
Figure 1 is a central vertical section of the improved spittoon as fitted in place
in the carriage floor, showing in full lines the valve in its normal closed position,
and in dotted lines the valve open to permit the escape of the contents of the
spittoon.
Figure 2 is a plan, and' Figure 3 a cross sectional plan on line 1-1 Figure 1.
Figure 4 is a vertical section of a trap forming a substitute for the balanced
valve, and
Figure 5 is a similar view of a revolving outlet for the same tube.
The same letters of reference indicate the same parts in all the figures.
The spittoon is a shallow funnel shaped tray A of circular or other form in plan,
provided with, or discharging into a downwardly extending outlet pipe B which
inay either be attached to the spittoon tray or not, so that the one may revolve on
or be removable from, the other. The lower end of this pipe B is furnished either
with a counterbalanced valve C adapted to be opened automatically by the weight
of the superincumbent column of liquid, or with a trap for sealing the outlet end of

page_text: the discharge tube, or a revolving hood and vane. for so directing the said outlet
end as to prevent the ingress of an up-draught.
In the example shown in Figures 1. 2. 3 the flap valve C is a disc faced with
indiarubber closing against the lower end of the tube B as a seat, said valve being
carried by a lever arm D pivoted at d in a bracket carried by the tube B, the tail
end of the lever being loaded by a weight E which rather more than counterbalances
the weight of the valve, so as to keep it normally closed but permitting it to open
from time to time, as shown in dotted lines in Figure 1 under the weight of the
column of saliva accumulated in the tube B.
Instead of using a balanced flap valve the tube B may be provided with a syphon
trap F, as shown in Figure 4, for the same purpose of permitting the escape of the
saliva without admitting an up-draught. Or the tube B may have a curved discharge
mouth or hood G mounted on its lower end so as to form a continuation of tube B
and pivoted to revolve about a vertical axis g under the guiding influence of a
vane H acted on by the wind or by the motion of the train through the air, so as
to always present the outlet in a leeward or rearward direction.
.. The spittoon tray may be made of metal enamelled or otherwise or of glass or
earthenware, and is adapted to be fixed in an aperture in the floor, and may or
may not be fitted with a cover or grating to prevent it being trodden on.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
1st. The herein described spittoon consisting of the funnel shaped tray and
discharge pipe adapted to be fitted in the floor and provided with a balanced valve
kept normally closed and opening under the superincumbent column as specified.
2nd. The herein described spittoon consisting of the funnel shaped tray and
discharge pipe adapted to be fitted in the floor, and provided with a sealing trap at
the outlet, as specified.
3rd. The herein described railway carriage spittoon consisting of the funnel
shaped tray and discharge pipe adapted to be fitted in the floor and provided with
a revolving discharge outlet hood controlled by a vane, as specified.
