PROVISIONAL SPECIFICATION.
Improvements in or relating to the Automatic Flushing of Water
Closets.
I, DAVID SMITH, of Fern Cottage, West Newport, in the County of Fife, N.B.
Artist, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to automatically flush water closets, in an improved
manner and by means of improved apparatus.
In carrying out my invention, according to one modification, I support the seat
of the closet upon pivots preferably placed near to the centre, in order that its
front and back may be able to rock, that is to say move up and down to a certain
extent. At the back of the seat and fixed to the floor is a bracket. A. lever
hinged at or about its middle is carried by said bracket, the one end of the lever
having a catch hanging from it, the other end being provided with a counterweight
which tends to keep the catch as well as the front of the seat, in its highest
position the lever being connected to the back part of the seat by means of a
joint or link. A sliding catch-designed to move either up or down-is also
guided by the bracket and has attached to its lowest extremity a cord or chain
which passes around suitably placed guide pulleys to the lever upon the flushing
cistern.
The action of the apparatus is as follows:-The seat being in its normal
position, with the front raised or tilted up, a weight placed upon the front
of the seat will raise or tilt the back of same, and in this manner will depress the
catch on the one end of the lever and raise the counterweight which is upon the
other. When the catch is fully depressed it engages with the sliding catch, so
that when the weight is removed from off the seat, the counterweight will raise
the catch taking along with it the sliding catch and the cord or chain connected
to the lever upon the flushing cistern. As the catch attached to the lever nears
its highest position it is disengaged from the sliding catch, which is thus free to
fall back into its previous position.

COMPLETE SPECIFICATION.
Improvements in or relating to the Automatic Flushing of Water
Closets.
I, DAVID SMITH, of Fern Cottage, West Newport, in the County of Fife, N.B.
Artist, 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 object of my invention is to automatically flush water closets, in an improved
manner, and by means of improved apparatus.
The accompanying sheets of explanatory drawings illustrate the method of
carrying out my invention according to one modification.
Figure 1. (Sheet No. 1.) represents a general view of the apparatus, showing
how it may be applied;
Figures 2. 3. 4. and 5. (Sheet No. 2.) respectively represent a side elevation,
showing the apparatus ready for use, a plan, an end view looking on A, and a side
elevation showing the apparatus after it has operated.

page_text: In these drawings the same reference numerals are used to mark the same or
like parts wherever they are repeated.
In carrying out my invention, I support the seat 6. of the closet upon pivots 7.
preferably placed near to the centre, in order that its front and back may be able
to rock, that is to say move up and down to a certain extent.
At the back of
the seat and fixed to the floor is a bracket S. A lever 9. hinged at 10. is carried
by said bracket, the one end of the lever having a catch 11. hanging from it, the
other end being provided with a counterweight 12. which tends to keep the catch
as well as the front of the seat in its highest position, the lever being connected
to the back part of the seat by means of a joint or link 13. A sliding catch 14.-
designed to move either up or down is also guided by the bracket 8. and has
attached to its lower extremity a cord or chain 15. which passes around a suitably
placed guide pulley or pulleys 16. to the lever 17. upon the flushing cistern 18.
To keep the valve 19. of the cistern open for a sufficient length of time, a fly
wheel 20. is provided, actuated by means of a segment of a spur wheel 21.
weighted at 24. which actuates a pinion 22; the fly wheel 20. and the pinion 22.
being both fixed upon an arbor 23.
The action of the apparatus is as follows:-The seat 6. being in its normal
position, viz. - -with the front raised or tilted up, as shown by the dotted lines
(Sheet No. 1.) a weight placed upon the front of the seat will raise or tilt the
back of same, and in this manner will depress the catch 11. on the one end of the
lever 9. and raise the counterweight 12. which is upon the other, as shown in
Figures 1. and 2. When the catch 11. is fully depressed it engages with the sliding
catch 14, so that when the weight is removed from off the seat, the counter-
weight 12. will raise the catch 11. taking along with it the sliding catch 14. and
the cord or chain 15. connected to the lever upon the flushing cistern. As the
catch 11. attached to the lever 9. nears its highest position, it is disengaged from
the sliding catch 14. by means of the camb 25. and the fixed pin 26, which is thus
free to fall back into its previous position. To allow of the valve 19. remaining
open for an appreciable time; the time of falling of the catch is governed by the
time taken to rotate the wheel 20. by means of the weighted segment 21; the
sliding catch 14. being connected to the weighted segment by means of the pin 27.
working in the slot 28.
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 :-
In apparatus for automatically flushing water closets :-
(1) The improved combination of parts hereinbefore described and shown in
the accompanying drawings, together with any mere modification or modifications
thereof.
(2) The mode of governing the time of falling of the sliding catch 14. by means
of the weighted segment 21, pinion 22, and fly wheel 20, as hereinbefore described
and illustrated in the accompanying drawings.
