COMPLETE SPECIFICATION.
Water Closet with Automatic Flush and Lid Raising Device.
I, ERNST SCHUSTER of 18, Prinzessinnen Strasse, Berlin, Germany, Manu-
facturer, 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 :-
The present invention relates to waterclosets and its object is to avoid the
necessity of opening and closing the lid when using the same, and also to provide
an automatic flushing device.
In order to make my invention more clear I refer to the accompanying drawings
in which similar letters denote similar parts throughout the several views.
Fig. 1 is a side elevation of my invention with the lid closed.
Fig. 2 is the same elevation showing the lid open.
Fig.
3 is a back elevation.
A is a bracket attached to the inside of the front part B of the woodwork of the
closet. Pivoted at C at the end of the bracket A is a bell crank lever D having
a long arm D¹ and a lower shorter arm D', the two arms having slots E' E
respectively in their ends. The arm D' is jointed by means of a pin working in its
slot E, to the lever pivoted at the bottom of the bracket A, said lever F having
pivoted thereto a vertical rod G. The latter projects downwards below its pivot
in a short arm to which is jointed a bent lever H, projecting in front of the
woodwork B of the closet and carrying the foot-board I. The rod G has its upper
end curved round at Gand is provided with a slot G' and a spring K. A stud
or pin arranged in the bracket A projects through the slot G and serves to hold
one end of the spring K whilst the lower end is held down by a cross pin in
rod G.
A lever L pivoted at the side of the closet and having its forward end arranged
in the slot G is adapted on being drawn down to depress a button or tip of a
water cock M.
The upper arm D' of the bell crank lever D is jointed to a lever arm N by
means of a pin sliding in the slot E', the lever arm N being rigidly attached at
its upper end to the lid O of the closet. The end of the lever arm N which is
jointed to the arm D' of the bell crank lever is attached to a spring P, which may
be adjusted by means of the stud or pin Q1 and the borings Q in the lever D₁
The lid O is attached to a seat R which is elastically mounted on the box B of
the closet, i.e. is adapted to be raised or depressed.
arm
The apparatus works in the following manner :-As soon as the foot-board I has
been depressed by the weight of a person standing on it, the lever H, which is
simultaneously depressed, lowers the rod G and lever F. The bell crank lever D
is thus operated and by means of the arm N rigidly attached to the lid O raises
the latter (Figs. 1 and 2) the seat R being lowered at the same time, in consequence
of the depression of the rod G. In addition to this however the rod L being
drawn down with the rod G depresses the button or tip of the water cock M thus
turning the water on or off, according as to whether it is required to flush the pan
when the lid is opened or closed. On the foot-board being released the parts
return to their position of rest under influence of a spring K. Thus a simultaneous
opening or closing of the closet and flushing the pan are effected.
Having now particularly described and ascertained the nature of my said inven-
tion and the manner in which the same is to be performed I declare that what I
claim is:
In a closet with automatic flush
1) A moveable footboard Ladanted on being dowrassed to raise the lid br moane

page_text: of a bell crank lever D and intermediate connections and lower the seat by means
of rod G and spring K, said rod G simultaneously actuating the pivoted lever L
and water cock M substantially as described.
2) A water closet with automatic flushing and lid raising device, in which, by
treading on a foot-board I a lever H is caused to depress a second lever F in such
manner as to simultaneously draw down a rod G and with it rod L thus actuating
a water cock M for flushing the pan, and to shift the position of a bell crank lever D
thus by means of the intermediate lever N rigidly connected to the cover 0
opening the latter, the seat R being lowered at the same time substantially as
described.
3) The device for automatically raising and closing the lid and simultaneously
flushing the pan, substantially as described and illustrated in the accompanying
drawings.
