Improvements in Water Closets.
1, XAVIER CHAUVET, of 58 Boulevard de Strasbourg, in the City of Paris,
France, do hereby declare the nature of my invention to be as follows:-
My invention relates to water closets, and has for its object, the construction and
arrangement of such a device, as to prevent the escape of sewer gas into the
apartinent and its surroundings.
My invention consists in the disposition of two pans superposed upon one another
each being fitted with a water tight valve, which are operated alternately, in order
to effect the object before described during the delivery of the soil into the sewer,
and always to maintain a gas tight joint in the soil pipe.
The apparatus in one form is composed of a pan, resting on a pipe or cylinder,
furnished with a freely hung and counterbalanced valve. This pipe is attached
to a lower chamber, the lower end of which is furnished with an indiarubber ring
against which a lower counterbalanced valve is maintained in contact by means of
an operating rod.
Another form of the apparatus has two pans superposed and mounted upon a
lower pan. The upper pan carries a valve fixed on a spindle on which is mounted
a pinion.
The second pan carries similarly a valve fixed on another spindle on which
another pinion is mounted. The two pinions receive their motion from a double
rack formed as a frame sliding in guides, and connected by rod to a handle or
button situated in a convenient position for handling.
The working of my apparatus in the first form described, is as follows:
When the material contained in the upper pan, has overcome the counter-
balance of the valve, the valve opens, and the material falls into the lower
receptacle, the valve returning to its normal position and the material is expelled
from the lower receptacle by operating the lower valve through the operating rod.
The excess of water serves to cleanse the valve of anything remaining thereon
and to assure the joint being hermetically sealed.
In the other form described the two valves are operated alternately by the
button carrying the double rack frame.
In drawing up the button vertically one rack produces a partial rotation in one
direction of the lower pinion to effect the opening of the lower valve during the
first portion of the upward motion of the double rack, and the rack produces a
partial rotation in the reverse direction of the same pinion, which effects the closing
of the same valve during the last portion of this movement of the double rack also
the first rack operates the pinion of the upper spindle which operates in its turn
the valve to open it.
During the descent of the double rack the first rack operates in a reverse
direction the upper pinion and according closes the upper valve.
In continuing the descent, the second rack engages the teeth of the lower pinion,
which opens the lower valve, and the first rack coming immediately in contact
with the same lower pinion closes the lower valve.
It will be obvious that the two valves now being closed, the excess of water
floods the pans, and rests in the bottoms of the same, thus ensuring the joints' being
completely sealed.

page_text: It will be readily understood that the alternate movement of the opening and
closing of the valves may be effected in many other ways.

COMPLETE SPECIFICATION.
Improvements in Water Closets.
1; XAVIER CHAUVET, of 58 Boulevard de Strasbourg, in the City of Paris,
France, do hereby declare the nature of my invention and in what manner the
sime is to be performed, to be particularly described and ascertained in and by
the following statement :-
My invention relates to water-closets and has for its object, the construction
.and arrangement of such a device as to prevent the escape of sewer gas into the
apartment and its surroundings.
My invention consists in the disposition of two pans superposed upon one another,
each being fitted with a water tight valve which are operated alternately in order
to effect the object before described, during the delivery of soil into the sewer,
and always to maintain a gas tight joint in the soil pipe.
In order that my invention may be the better understood I will now proceed
to describe it in relation to the drawings hereunto annexed reference being
had to the letters and figures marked thereon.
Figure 1 is a vertical section of my invention showing the upper valve free and
the lower valve controlled by an operating rod.
Figure 2 is a vertical section of the apparatus with the two valves operated by
a rack and pinion movement.
Figure 3 is a plan of the sames.
Figure 4 is a detail view of the rack which operates the pinions on the spindles
carrying the valves.
Figure 5 is an outside view of the apparatus.
The apparatus shewn in Fig. 1 is composed of a pan a, resting on a pipe or
cylinder a', furnished with a freely hung and counter-balanced valve b. This pipe
a¹
is attached to a lower chamber c, the lower end of which is furnished with an
india rubber ring d against which a lower counter-balanced valve e is maintained
in contact by means of the operating rod f.
Figure 2 shows two pans g h mounted upon a lower pan i. The pan g
valve k fixed on the spindle on which is mounted a pinion m.
เ
carries a
The pan carries similarly a valve n fixed on a spindle o on which the pinion p
. is mounted.
.
The pinions m and
p receive their motion from a double rack qr formed as a
frame, sliding in the guides ss, and connected by a rod to a handle or button t
situated in a convenient position for handling.
The working of my apparatus as shown in Fig. 1 is as follows:-
When the material contained in the upper pan, a, a¹, has overcome the counter-
balance of the valve b, the valve opens and the material falls into the receptacle c,
and is expelled from it, by operating the valve e through the operating rod f.
The excess of water serves to cleanse the valve of anything remaining thereon
and to assure the joint being hermatically sealed.
In the Figures 2 to 5 the two valves k, n are operated alternately by the button t
carrying the double rack frame q, r.
In drawing up the button t vertically the rack q produces a partial rotation in
one direction of pinion p to effect the opening of the valve n during the first portion
of the upward motion of the double rack, and the rack r produces a partial rotation
in the reverse directiou of the pinion p, which effects the closing of the valve n;

page_text: and during the last portion of this movement of the double rack the rack q operates
the pinion m which operates in its turn the valve k to open it.
During the descent of the double rack, the rack g operates in a reverse direction
the pinion m and accordingly closes the valve k.
which
In continuing the descent the rack engages the teeth of the pinion p
opens the valve n, and the rack 9 coming immediately in contact with the same
pinion p closes the valve n.
It will be obvious that the two valves now being closed, the excess of water floods
the pans, and rests in the bottoms of the same, thus ensuring the joints being
completely sealed.
It will be readily understood that the alternate movement of the opening and
closing of the valves may be effected in many other ways.
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. A water closet having two valves one superposed above the other, and
operated alternately, substantially as described.
2nd. In such a water closet, the combination of a free valve 6 with a valve e
operated by operating device f, substantially as described in relation to Figure 1 of
the accompanying drawings.
3rd. In such a water closet, the combination of two superposed valves. k n
adapted to be operated alternately, to effect the constant sealing of the soil pipe,
substantially as described and illustrated in Figures 2, 3, 4, and 5 of the accom-
panying drawings.
