PROVISIONAL SPECIFICATION.
Combination of a Water Tap and Steam Valve for Domestic Boilers
or Hot Water Service.
I, ERNEST WILLIAM BEECH, of 11 The Pavement, Wanstead, Essex, Engineer,
do hereby declare the nature of this invention to be as follows:
This invention relates to combining a water tap and steam valve for domestic
boilers or hot water service.
For the purpose of my invention, I weight or spring press a valve to hold it on
its seat against the pressure or head of water to stop the flow. The spindle of
said valve has a cam or other shaped appliance so that the turning or other motion
of a handle causes the passage through the tap to be opened and to close
automatically on a reverse motion of the handle.
The combined appliance can be fitted to a kitchen or other boiler for drawing
off purposes, and should extra pressure be formed the valve being free to rise
when the weight or pressure is overcome by steam or water pressure an escape
automatically happens.
The invention is applicable to any desired part of a hot water system, such as
to tanks, pipes, closets, sinks, baths where a tap is desired.
By this combination, the use of the tap as a draw off will prevent the valve
sticking on its seat or of becoming clogged as would be the case if left for a long
period without movement.

Combination of a Water Tap and Steam Valve for Domestic Boilers
or Hot Water Service.
I, ERNEST WILLIAM BEECH, of 11 The Pavement, Wanstead, Essex, Engineer,
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 —
This invention relates to combination of a water tap and steam valve for
domestic boilers or hot water service.
For the purpose of my invention, I weight or spring press a valve to hold it
on its seat against the pressure or head of water to stop the flow. The spindle
of said valve has a cam or other shaped appliance so that the turning or other
motion of a handle causes the passage through the tap to be opened and to close
automatically on a reverse motion of the handle.
The combined appliance can be fitted to a kitchen or other boiler for drawing
off purposes, and should extra pressure be formed, the valve being free to rise
when the weight or pressure is overcome by steam or water pressure an escape
automatically happens.

page_text: The invention is applicable to any desired part of a hot water system such as to
tanks, pipes, closets, sinks, baths where a tap is desired.
By this combination, the use of the tap as a draw-off will prevent the valve
sticking on its seat or of becoming clogged as would be the case if left for a
long period without movement.
My invention is represented on the annexed drawings.
Figure 1 section of tap for spring resistance under ordinary pressure but capable
of yielding under extra pressure as before referred to.
Figure 2 section of tap slightly modified but having same advantages.
Figure 3 section of weighted tap for same purpose.
Figure 4 elevation of lower end of inner tube.
Figure 5 modified arrangement at head of Figure 2.
Figure 6 section of collar.
Figure 7 plan of ebonite or other seating plug or disc valve.
Figure 8 elevation of valve complete.
Referring to Figure 1, A is the tap barrel or body formed in the usual manner
of screw down taps except that the upper neck B is of greater height into which
the gland or cap C is screwed and locked by set screw D. E is a helical spring
pressing against the lower edge of the cap C and bearing on a sliding collar F
which has a rising and falling motion on guides G, G, formed on the inner wall of
the neck B. The collar F is screw threaded for the screwed part of the stem H
of the handle I to pass through and by which the collar F is operated according
to the direction in which the handle may be turned.
The lower end of the stem H has a deep foot J as part of same, this having a
hollow of conical or equivalent shape with a couple of V notches in the side wall
for the reception of the leathers J on the disc K of the bulbous head L of the
valve proper M to lodge in and be held loosely by a screw pin N, said valve M
being of ebonite or other suitable material which is held to the lower disc K
by a pin and nut as shown.
A space P is left between the collar F and foot J for limiting the lift motion of
the valve M and any water escaping past the valve M when the tap is open escapes
through and down the relief pipe Q.
I surround the valve stem H by a sleeve R which can have a rising and falling
motion with the collar F, stem H, handle I, and valve M when the pressure exerted
in the tap is greater than that to which the spring E is set, the valve M being then
free to rise from its seating to allow of the extra pressure escaping without
regard to the tap as a tap for drawing off purposes only.
The loosely fitted valve M (and its attachment) is self-adjusting and finds its
own seating and while being lowered, it also turns with the handle and is forcibly
put into contact at the termination of the screwing down operation by the V shaped
notches and feathers engaging in same.
By this arrangement when the tap is being opened the foot J rises first with the
stem H, the valve M turning on its seat and then becomes lifted by the further
rotation of the handle I.
Many of the same appliances exist in the sectional elevation shown at Figure 2
but are differently arranged. In this sectional elevation I make the lower part of
the stem H hollow and place the spring E within it; the head L of the valve
disc J, in this case forms part of the valve proper or has a valve affixed as in the
case before mentioned.
Instead of the neck B being part of the barrel A, I screw a neck on to the
shoulder S and I notch the lower end of the sleeve R, as seen at Figures 2 and 4
for the passage of water when the tap is opened from either cause, two of the
notches being somewhat longer than the others for uprising of the valve J under
extra pressure, a couple of horns T, T, on foot or valve J being guided for a
similar purpose before explained.
Referring to Figure 3, it will be seen that I employ weights E on the outside of
the tap instead of a spring or springs within for resisting the passage of water at

page_text: normal pressure unless the handle be turned but in which the valve will lift under
an excessive pressure such as that produced by presence of steam.
There are several ways or means for obtaining the necessary set of spring
pressure in my tap and in order to prevent the crowding of the spring by screwing
the stem down too far, I employ an adjustable collar U Figure 5, and fix it from
time to time by the set screw V as the valve becomes worn. Figure 6 represents
the collar F with a half diameter thread cut in it for rapid rise and fall screw
action of the valve stem H as a cam, of which the shallow or slow screw thread is
an equivalent.
The taps if applied to bath supply can be used for either hot or cold water taps
and identified by tablets let in the handle, as at Figure 1.
I am aware that combined water tap and steam valves were in use before the
date of my application for Patent, I therefore make no claim to such an apparatus
in a broad sense.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The construction and arrangement of combined water tap and steam valve shown
on the annexed drawings Figure 1, and its modification Figures 2 and 3 as
applicable to domestic boilers or hot water service for the purposes described
whether a spring or weight be fitted to resist steam pressure, as set forth.
