Improvements in or connected with Flushing Cisterns.
We, THOMAS GARFORTH RHODES, of Albert Terrace, Kirkstall, Leeds, Engineer,
and RAYMOND GAUNT, of The Mount, Stanningley, near Leeds, Engineer, both in
the County of York, do hereby declare the nature of this invention to be as
follows:-
-
Our invention refers to siphonic flushing cisterns, and our object is to so improve
the construction of the mechanical parts, that the same are stronger and less
liable to become defective through uneven wear, and the noise caused by the
piston and its connections is reduced to a minimum.
According to our invention, we provide an elastic buffer which is attached to
the piston of the siphon cylinder, in such a manner as to project on opposite sides
at the upper part of same. The position of the said elastic buffer is such that in
the reciprocations of the piston it comes against the end of the cylinder in one
direction, and against the pending flange of the said cylinder at the feed end of
same, thus effectually deadening the movements of the piston and parts connected
to it, and preventing the rattling hitherto experienced.
Instead of forming the bracket for carrying the lever with an angle plate for
attaching to the top edge and side of the cistern, we provide it with two flat sur-
faces at right angles to each other which permit of its attachment to two adjacent
top edges, thus effecting a stronger connection with the cistern and dispensing with
the unsightly angle plate on the face of the cistern. The lever is carried on a
pin supported by two lugs which stand on the upper surface of the bracket, and the
bracket is cut away between the lugs, in such a manner as to allow of the free
movement of the lower arm of the bell crank lever in the direction of its movements,
but which prevents any side play of the lever, through the bearing pin working
loose or from other cause.

in and by the following statement:-
Our invention refers to siphonic flushing cisterns, and our object is to so improve
the construction of the mechanical parts, that the same are stronger and less
liable to become defective through uneven wear, and the noise caused by the
piston and its connections is reduced to a minimum.
In order that our invention may be clearly understood, we will proceed to describe
the same with reference to the accompanying drawing in which similar letters
refer to like parts in both figures.
Figure 1 is a longitudinal section of a cistern fitted with the improvements
forming our invention, and Figure 2 is a detail view.
According to our invention we employ an elastic buffer A which is attached to
the piston B of the siphon cylinder C, in such a manner as to project on opposite
sides of the pistons at the upper part of the same. During the reciprocations of
the piston B, the buffer A comes against the end D of the cylinder in one direction,
and against the pending flange E of the said cylinder C at the feed end of same,
thus effectually deadening the movements of the piston B and its connected parts
and preventing the noise and rattle hitherto experienced.
:
F is the piston rod which is connected to the lower arm of a bell crank lever G.
The latter is carried on a pin H. held by lugs J of a bracket K, and the said bracket
K is provided with two flat surfaces L and M at right angles to each other which
permit of the attachment of the bracket K to the adjacent upper edges of the
cistern N, thus effecting a stronger connection with the cistern N and dispensing
with the unsightly angle plate usually employed on the face of the cistern. The
bracket K is cut away at P between the lugs J in such a manner that the side
guiding surfaces R of the cut away portion P act as guides and prevent excessive
side play of the lever G, through the bearing pin working loose or from other cause.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is: -
1. The elastic buffer A mounted in the piston B, substantially as and for the pur-
poses set forth.
f
2. The bracket K having two flat surfaces L and M at right angles to each
other, substantially as and for the purposes set forth.
3. The bracket K having a cut away portion P and side guiding surfaces R,
substantially as and for the purposes set forth.
