COMPLETE SPECIFICATION.
Fig. 4 is a detail plan view of a seat.
Fig. 5 is a detail view of a pivot carrier.
Similar letters indicate corresponding parts.
In this drawing the letter A indicates a bowl or basin having a cover B. The plug
stopper or plunger C is attached by a link or rod D to the cover B. The cover is
jointed at E to a suitable support such as the framework F of the closet. When the
cover B is opened, the plug C is drawn out of the outlet of basin B and the arm G
which is fixed to the cover, strikes against the lug or stud H mounted on the spring I
secured to the swinging arm K.
The arm K swings on the oscillating links L and said arm K is connected by a link M
with the valve N. The opening of the cover B swings or moves the arms G K in the
direction of arrow 1. (Fig. 1) to the position shown in Fig. 2 thus raising the valve N
against its own weight to close the outflow of bowl A. A stop O prevents excessive
inotion in the direction of arrow i and when the parts are in the position shown in
Fig. 2 the links L M are on the dead centre or slightly beyond the dead centre in the
direction of arrow 1 and kept stationary by stop Ŏ sothat the valve N is held closed.
A stud or shoulder P is secured to a spring or spring arm Q on the arm K so that
when the cover B is being opened the arm G rides over or past the stud P. When the
cover B is being closed, the arm G strikes against the stud P and pushes the arm K
in the direction opposed to arrow 1 until the links L M are past the dead centre, when
the valve N drops open by its own weight and the arm K is restored to the position
shown in Fig. 2. The arm G following after the arm K rides over the spring I and
stud H until said arm with the cover B have resumed their starting positions
Fig. 1.
The link M in its movements imparts motion to the arm R to which is connected
the chain S leading to the water tank (not shown) and which with its valve arrange-
ment may be of any suitable well known construction. When the valve N is closed
the actuation of the chain S causes a wash to flow so that a supply of water rests
on the valve N. When the valve N is opened the supply of water flows off
and as the plug C closes the basin, another wash takes place so that a supply of water
then rests on the plug C.
When the cover B is opened (Fig. 2) the plug C is drawn to its opening position by
the rod D and is swung back and concealed in a recess in the bowl so as to be out of
the way, a slit T in the seat U (Fig. 4) allowing the link D to swing well back. The
pivot V for the link D can be supported in a pivot carrier consisting of a shell or
case W of sheet metal having a suitable ornamental form and provided with eyes ✗
for the pivot V. A series of eyes placed at different distances from the cover can be
provided so that the link D can be adjusted nearer to or further from the cover B as may
be required to cause the plug C to tightly close the basin.

page_text: It will be noticed that the cover controls the operation of the mechanism since the
opening of the cover closes the valve N and causes a wash of water so that water rests
on the valve N and when the cover is closed the valve N opens allowing the water and
contents of the bowl to flow off after which the plug C hermetically closes the bowl
and a second wash supplies an amount of water which rests on the plug C and serves
as an additional seal or closure to assist the plug in preventing foul gas from
passing into the bowl from its outlet. The bowl is thus thoroughly cleansed and
sealed by the operation of opening and closing the cover.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is.
1. The combination with the basin having a valve N of a cover provided with a
plug for the basin said cover being connected to the valve substantially as
described.
2. The combination with the basin having a valve N and a cover provided with a
plug for the basin of an oscillating arm K a link M connected to said arm and to the
valve and an actuating arm G secured to the cover and made to engage the arm K
substantially as described.
3. The combination with a bowl, a seat having a rear slut, and a cover over the seat,
of a bowl stopper or plunger and a swinging link or rod connected to the stopper or
plunger and to the cover, said link or rod lifting the stopper or plug and entering the
rear slot of the seat when the cover is elevated substantially as described.
