improved Push Valve or Tap for Drinking Fountains.
We ROBERT HARDING and GEORGE HARDING trading as R. Harding and Son
of 75 Arodene Road Brixton Sanitary and Hydraulic Engineers 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:―
Our improved push valve or tap for drinking fountains and the like consists of a
valve of special design and construction secured and protected in an iron or other
metal shield which acts as guide for push to prevent its being unscrewed thereby
dispensing with the ordinary pin and slot guide.
In the following description the term outer part shall refer to that part of the
valve or tap covered by the shield where the push and nozzle are seen.
The term inner part shall refer to the part which enters through the cistern or
vase and is screwed up with the backuut inside to which also the valve is.
attached.
The outer part A of body of valve is the same as the push B (hexigan or any
other shape) and is larger than the inner part of body C thus forming a shoulder D-
for fixing.
The inner part of body C which can be extended to any length the thickness of
cistern E or vase may require to recieve backnut F inside for screwing up, has a.
tongue G cast to the same extending from the shoulder of outer part of body A,
passing through inner flange of shield H to reach an indent in outer surface of
cistern or vase I, in order to prevent all from being unscrewed from the outside.
To the inner part of body C a seating J is affixed for rubber faced valve K to-
close against with an internal three web guide L for spindle M this seating can be.
renewed to the same body or replaced with a smaller one if put under pressure, on
this three web guide L rests one end of the spiral spring N around spindle M
whilst the other end of spring O presses out the push to keep valve closed.
The stout part of spindle P attached to the push B works in a cupleather R to-
prevent escape of water.

page_text: .
The push itself B is of hexigan shape or any other shape not circular, which
works freely in a hole of the same shape S in an iron or other metal shield T as
guide to prevent its being unscrewed, instead of the ordinary pin and slot guide
which has often proved untrustworthy.
The shield T which is strongly made of cast iron or other metal is an ornamental
covering with an inner flange H attached by which it is secured when screwed
up with backnut F, forming an immoveable support, (an iron shield is best for
public use).
The valve is passed through the front or outer part of this shield T, in which
is a slot U large enough to recieve nozzle V allowing the push B to project
of an inch.
The front of this nozzle V is formed to fill the slot in shield U, and to correspond
with its design and also forms one side of guide.
The shoulder W on body of valve A thus holds-the inner flange H of shield T
so that when the backnut F is screwed up inside the cistern or vase E all is
Becured together.
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.
1st. The hexigan or other shape push B not circular working in a guide S
outside itself, in order to dispence with the ordinary pin and slot guide.
2nd. The adopting a cast iron or other metal shield T to constitute the outside
guide of push B and to protect the body of valve A, and also make a secure fixing.
3rd. To prevent escape of water at push B by means of cupleather R.
