PROVISIONAL SPECIFICATION.
Improvements in Taps and Fittings for Water Supply.
CHARLES HENRY ADAMS and CHARLES HENRY HAINES ADAMS, both of
1 South Street, Guildford in the County of Surrey, Engineers do hereby declare
the nature of this invention to be as follows:-
Whereas ordinary garden supply and other exposed taps are liable to become
blocked with ice, in time of winter when the atmosphere is at a low temperature,
our invention relates to bib and drawing taps for exposed situations, and is to
prevent the same from becoming blocked with ice. We therefore construct our
anti-frost tap in part only at the exposed position, and the valve or valves
whereby the flow of water is regulated, at an in-exposed part of the pipe, and
a bye-pass or throttle valve is so arranged that by the flow of the delivery water
or otherwise, it closes a small valve aperture in the pipe, which said small valve
when the flow of water is stopped will be automatically opened, thereby allowing
the water above the valves to drain off and so prevent the supply tap becoming
blocked with ice.
Dated this Twenty-third day of September 1893.

Improvements in Taps and Fittings for Water Supply.
We CHARLES HENRY ADAMS and CHARLES HENRY HAINES ADAMS, both
of 1 South Street Guildford in the County of Surrey, 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 :-
Whereas ordinary garden and other exposed taps are liable to become blocked
with ice in time of winter when the atmosphere is at a low temperature, our
invention relates to bib and drawing taps for exposed situations, and is to prevent
the same from becoming blocked with ice.
We therefore construct our anti-frost tap in part only at the exposed position
and the valve or valves whereby the flow of water is regulated, at an in-exposed
part of the pipe, and a bye-pass or throttle valve is so arranged that by the flow of
the delivery water or otherwise it closes a small valve aperture in the tap, which
said small valve when the flow of water is stopped will be automatically or other-
wise opened, thereby allowing the water in the tap above the valves to drain off,
and so prevent the supply tap becoming blocked with ice.
In constructing this tap the parts are so arranged that the whole of them can be
examined and repaired by unscrewing or unfixing and removing the drawing tap
from the ground or supply pipe.
In order that the principle of the tap may be understood we have shown in
Figure 1, enlarged sections of the parts of a tap, which is necessarily of an elongated
form, and in which it will be seen the drawing part or appliance is at one extremity.
of the tap A with turnscrew or other mechanism which is for the purpose of
operating the supply valve B upon its seat D, which is situated at the other
extremity of the tap, and the operation of the apparatus is as follows:- When the

page_text: -drawing mechanism is manipulated for drawing water the valve spindle E opens
the valve B from its seat D, at the same time by the flow of water through the tap
or by special mechanism the draining valve C is closed, and on the valve B being
closed by the mechanism of part A upon its seat D, the draining valve C is opened
by gravitation or otherwise thereby allowing the contents of the tap to drain away,
and so the tap cannot become blocked with ice.
Figure 2 is a view of the tap as fixed in position on a garden supply pipe, and
the letters of reference are used for the same parts, and here we desire it to be
noted, that any convenient kind of mechanical action or appliance can be employed
to open or close the valve or valves, as well as any convenient kind of valves or
valve seatings, can be used in the place of those described or illustrated in the
-drawing.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The constructing of bib and drawing taps of such an elongated form as to
allow the drawing appliances or parts to be in the usual position, where they are
necessarily exposed to the action of frost, whilst the valve or valves of same are
situated beneath the ground or other in-exposed position, one of the said valves to
be so arranged to open automatically or otherwise, so that it will allow the water
to drain off from the elongated portion of the tap after use, and to automatically or
otherwise close whilst the tap is in use and water is being drawn therefrom.
2. The constructing of a drawing tap with an automatic or other draining valve
attached and situated between the turnscrew or other mechanism whereby the
drawing or supply valve is operated, and the said drawing valve.
