COMPLETE SPECIFICATION.
An Improved Valve for Cisterns and Tanks used for Flushing
Purposes and the like.
I, BRUNO JOHANNES VON HOSSTRUP, of 13 Schopenstehl, Hamburgh, Manu-
facturer, do hereby declare the nature of my said 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 this invention is an improved valve for cisterns and tanks used for
flushing purposes and the like, which differs from the valves hitherto used for this
purpose by the body of the valve having a double guide, the mode of fixing the
tightening disc and the connection between the latter with an air cushion, which
renders this arrangement so much more advantageous that by means of these
improvements an absolute tightness is obtained, in consequence whereof the waste
of water taking place with the various valves hitherto constructed is entirely
obviated.
The accompanying drawings show one method of carrying this invention into
effect. The body of the valve which is connected with the bell or tank a forming
the water closing means, can be raised by the aid of the lever band has a double
guide consisting of the crown e forming the body proper of the valve on the one
hand and of the box or shell d screwed into the said crown on the other hand.
This box is provided with an outer flange e between which and the crown c the
tightening disc or washer f of india rubber or of any other suitable material is
locked by screwing c and d together. The valve seat consists of the box or shell g
which is let into the central bottom opening of the tank and firmly screwed thereto
by means of the nut h. The material which connects the upper and wider part
and the lower and narrower part of the box g is turned so as to form on the surface
a small circular rib i and is bored or hollowed out deeply inside the same, so that
an air cushion k is formed between the lower part of the box g and the tightening
disc the latter of which is firmly pressed against the rib i when the valve is
closed, that is to say against the flange e. The upper part of the box g and the
box d are provided with slots through which when the valve is raised, the water
can flow downwards from the tank. The body of the valve has likewise a
double guide which prevents the same from striking the valve seat obliquely and
from springing out of position. The air cushion k is provided so as to allow
sufficient play when the disc is being tightened to form a more perfect joint as
well as to increase the elasticity of the same. The conduit is provided for the
Blushing water which is opened and closed by a cock actuated by a suitable ball
valve or float as is usual in the generality of water tanks.
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 :-
A valve for tanks and cisterns used for flushing purposes and the like, characterized
by the body of the valve having a double guide c and d in its seat, and by the
formation between, of a tightening disc fixed by means of the box d to the body
of the valve and the valve seat provided with a rib i at the joint of an air cushion k

page_text: so as to avoid an oblique stroke as well as the escape of the body of the valve
from its guide on the one hand while increasing the elasticity of the joint on the
other.
