PROVISIONAL SPECIFICATION.
Improvements in or relating to Water-closet Basins.
I, CARL GUSTAV BAUMGARTEL of Dresden-Altstadt, Saxony, in the German
Empire, Builder, do hereby declare the nature of this invention to be as follows:-
This water seal for hermetically closing w.c. basins is distinguishable in the first
place by its arrangement at the upper edge of the basin, and besides, offers the
advantage of reducing the consumption of water. Its position at or near the basin
top is advantageous in this respect, that, unlike other devices employed for similar
purposes, it causes the whole of the capacity of the basin to be hermetically closed,
so that any matter which may have adhered to the basin wall is prevented from
spreading deleterious smells in the apartment.
The basin is provided at its upper end with a groove which may be situated
either within the basin or on the outside thereof, or along the upper surface of the
edge of the basin. Whatever the situation of the groove, the frame or fitting,
carrying it, should in all cases be tightly cemented to the basin.
Into the groove
fits the downwardly projecting vertical rib or flange of the lid. The groove is kept
constantly filled with water and for this purpose an arrangement is adopted, which
is based on the same principle as the existing trap.
The groove is connected with a second basin to which leads a pipe extending
from a tank or reservoir which, on being filled, is tightly closed. In proportion as
the water level sinks, a fresh supply of water is admitted through the pipe to make
up for the deficiency, so that the water level always remains practically constant in
the groove.
The lid is operated by means of a handle preferably mounted on a spindle. The
lid is rigidly connected with the said spindle and when the handle is raised, or the
spindle turned by means of the handle, the lid is raised out of the groove or turned
on one side. In closing, the proper adjustment of the lid in relation to the groove
in ensured by stops or tappets presenting inwardly inclined surfaces, against which
are adapted to slide pins secured to the lid. These stops also keep the lid from
shifting out of position.
In one form of the apparatus the lid which closes the basin and which for dis-
tinction I will designate a is so connected with a second lid which closes the
orifice of the seat, that when the lid is operated for the purpose of closing or
opening the seat, lid a is correspondingly moved up or down. This lid is rigidly
connected with a sleeve adapted to slide along a shaft but not to revolve thereon.
With the sleeve engages one arm of a bell-crank lever upon the second arm of
which during the first part of the movement of the lid acts a tappet mounted upon
a spindle with the result that lid a is raised out of the groove. The concentric
surface of the tappet then, during the remaining part of the movement of lid 6 acts
in such a manner that lid a is retained in the desired raised position, while a
toothed segment mounted on a spindle engages with a pinion or wheel secured on
the other spindle whereby the lid a is turned to one side. As the lid is closed,
the reverse movements take place. In this arrangement also tappets or stops are
employed.
It will be understood that all the details requisite for carrying out this invention
cannot be set forth in this Provisional Specification, these are reserved for their
proper place in the Complete Specification. Modifications in the parts described
may be made without departing from the spirit of this invention.

Improvements in or relating to Water-closet Basins.
I, CARL GUSTAV BAUMGARTEL, of Dresden-Altstadt, Saxony, in the German
Empire, Builder, 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:-
This water seal for hermetically closing water-closet basins is distinguishable in
the first place by its arrangement at the upper edge of the basin, and besides,
offers the advantage of reducing the consumption of water. Its position at or near
the basin top is advantageous in this respect, that, unlike other devices employed
for similar purposes it causes the whole of the capacity of the basin to be hermeti-
cally closed; so that any matter which may have adhered to the basin wall is
prevented from spreading deleterious smells in the apartment.
In the accompanying drawings
Figs. 1 and 2 show one form of the improved water-scal, in which the lid is
moved independently, whereas in the form shown in Figs. 3 to 5 motion is imparted
to the lid through another lid closing the orifice of the water-closet. The detail
views Figs. 6 and 7 show the main parts of the water seal on a larger scale.
V¹
The basin a is provided at its upper end with a groove which may be situated
either within the basin as shown in Fig. 6 or on the outside thereof, or as shown in
Fig. 7 along the upper surface of the edge of the basin. Whatever the situation of
the groove the frame or fitting carrying it should in all cases be tightly cemented
to the basin. Into the groove fits the downwardly projecting vertical rib or
flange cof the lid. The groove is kept constantly filled with water and for
this purpose an arrangement is adopted which is based on the same principle as the
existing trap. The groove is connected with a second basin d to which leads a
pipe extending from a tank or reservoir d² which, on being filled, is tightly
closed. In proportion as the water level sinks within db a fresh supply of water is
admitted through the pipe to make up for the deficiency, so that the water level
always remains practically constant in the groove.
C
The lid is operated by means of the handle e' preferably mounted on a spindle e
Figs: 1 and 2. The lid is rigidly connected with the said spindle e and when the
handle is raised or the spindle turned by means of the handle, the lid c is raised out
of the groove or turned on one side. In closing, the proper adjustment of the
lid in relation to the groove is ensured by stops or tappets f¹ Fig. 5, presenting
inwardly inclined surfaces, against which are adapted to slide the pins c² secured to
the lid c. These stops also keep the lid from shifting out of position.
.In, the form of apparatus shown in Figs. 3 to 5 the lid c which closes the basin is
so connected with the second lid g, which closes the orifice of the seat, that when g
is operated for the purpose of closing or opening the seat, c is correspondingly
inoved, up or down. The lid c is rigidly connected with the sleeve / adapted to
slide along the shaft i but not to revolve thereon. With this sleeve / engages one
arm of the bell-crank lever upon the second arm of which during the first part
of the movement of acts a tappet h² mounted upon the spindle g! with the result
that is raised out of the groove b. The concentric surface of the tappet then,
during the remaining part of the movement of g acts in such a manner that c is
retained in the desired raised position while the toothed segment mounted on gl
engages with the pinion or wheel secured on i whereby the lid c is turned to one
side. As the lid g is closed the reverse movements take place. In this arrangement
also tappets or stops f¹ are employed.
C
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, 1 declare that what I
claim is,
f
frumed at the

page_text: upper edge of the basin and adapted to keep filled with water for the reception of
the vertical flange or rib of the lid.
2. The modification of the water seal referred to in the preceding claim in which
the lid c is connected in such a manner with the lid y closing the seat that when g
is opened or closed c moves in the same direction.
