Improvements in the Construction and Arrangement of Stand Pipes
or Posts for Water Main or Services.
I WILLIAM RICHARD HOPKINS CHIPPERFIELD, of Atherstone, Warwick-
shire, Civil Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to the construction and arrangement of stand pipes or
posts for water mains or services, and its primary object is, to provide means
whereby the inconvenience through frost is almost, if not entirely obviated; also
to effect a prevention of waste; also to provide improved facilities in construction,
giving access to the various parts, and also improvements in the arrangement of the
said parts themselves.
As is well known very much inconvenience and annoyance is occasioned in stand
pipes of ordinary construction, by reason of the water standing therein becoming
frozen, during severe frosts, and as before intimated, it is one of the primary
objects of this invention to lessen or remove this annoyance.
Its construction is somewhat as follows-A rectangular cast iron box is provided
which is sunken or let into the ground level or thereabouts with the surface.
Near the bottom is provided an inlet through which enters the main supply pipe
to which is attached a stop cock, so that at any time the water may be here turned
off to allow of removal, repairs, or inspection of the rest of the fittings. Connected
up to this stop cock is a stop or supply valve having a vertical spindle which passes
upwards to near the cover of the box, or in some instances may be carried to a
higher point according to requirements.
The spindle of this valve above the packing box has a screwthread formed
thereon of any suitable pitch and size, which works in a screw nut which latter is
fixed from the valve box, or carried upon any suitable fixed bracket or bar, so that
upon the rotation of the said spindle, the valve is opened or closed. Immediately
above this screw, a lever or arm is secured to the spindle, and to its outer end is
connected the one end of a spiral spring, the other end of the latter being attached
to the side of the box or other fixed part provided therein, in such a manner that
its tendency is always to automatically close the said valve. Instead however of
the spiral spring, any other form of spring may be used which will effect the same
purpose. Also, in some cases, instead of the screwthread upon the spindle and the
fixed screwnut, a cam like or inclined plane surface or surfaces, may be formed
upon or about the spindle, agreeing with and acted upon by corresponding surfaces
upon the lever so that upon the rotation of the spindle the valve may be opened or
closed as before.
In cases where the stop valve spindle is only carried upward to near the large
rectangular box cover, such cover is provided with a recess in which is placed the
valve spindle stuffing box. At the upper end of the spindle a square or other
shape is made to receive a turnkey. This recess is further provided with a
removable cover (let in flush with the main cover) in which, and immediately over
the valve spindle, is a hole through which the said turnkey may be passed. The
external shape of this key, and the hole through which it passes are so shaped, as
that the key cannot be withdrawn except when the valve is closed.
On the aforesaid large cover, there is also provided a recess or box part, in which
is situated a valve of peculiar construction, and which serves a two fold purpose
viz.: that of delivery, and also of draining off any surplus water from the vertical
delivery pipes. Or if preferred this valve may be situated in the main box and

page_text: below the ground line. This valve is connected at its underside, with the pipe
leading from the aforesaid stop or manipulative valve, and is further furnished with
an upward final discharge pipe or outlet. This valve is of the nonreturn type, and
having its flap preferably at an angle. In the valve box and upon the upper side
of the movable flap is an overflow or outlet, leading away. to a drain or other escape,
the face of which is so arranged, that when the main stop valve is opened and the
water lifts the said nonreturn valve, the said valve upon its upper side closes this
said outlet, and thus the water uninterfered with, passes on through the discharge
pipe; but upon the main valve being closed and the forward force of the water
ceased, the nonreturn valve closes, and in so doing opens the overflow outlet and
permits the escape of the water then standing in the discharge pipe and valve box,
hence there will remain no water in these parts to become frozen and so to impede
the working of the whole. The precise form of this valve may be modified, but yet
effect the same purpose, that is, when being opened for usual supply purposes, it shall
close the overflow outlet, and vice versa. Connected with this overflow outlet is a
turn cock, which, during the cold weather is left open, to permit of the automatic
action of the double acting valve, but which during the warmer weather (when no
freezing is likely to occur) may be closed, and thus prevent the overflow discharge
of water from the discharge pipe.
Above this nonreturn or double acting valve is erected the usual cast iron
column within which is concealed the discharge pipe and from which the outlet
protrudes.
If preferred this cast iron pillar may serve also to conceal and carry upwards the
main valve spindle.
The main box and the compartment in which is the nonreturn valve box,. is now
filled with silicated cotton or other non-conducting material.to more perfectly
prevent the access of extreme cold.
As before intimated, the spindle of the main stop valve may be.extended.to any
convenient height, and when so extended, either a removable..key similar to that
already described, may be used or a fixed handle or lever, and in some cases, if
necessary intermediate connecting mechanism may be employed from the handle or
lever to the said valve.

Improvements in the Construction and Arrangement of Stand Pipes
or Posts for Water Main or Services.
I WILLIAM RICHARD HOPKINS CHIPPERFIELD, of Atherstone, "Warwick-
shire, Civil 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 the construction and arrangement of stand, pipes or
posts for water mains or services, and its primary object is, to provide. means
whereby the inconvenience through frost is almost, if not entirely obviated also to
effect-a- prevention of waste; also to. provide improved facilities in construction,
giving access to the various parts, and also improvements in the arrangement.of the
said parts themselves.
As is well known very much inconvenience and annoyance is occasioned in stand
pipes of ordinary construction, by reason of the water standing therein.becoming
frozen during severe frosts, and as before intimated, it is one of the primary objects
of this invention to lessen or remove this annoyance.
In order to more clearly explain the nature of this my said invention, and in
what manner the same is to be performed, I have appended hereunto illustrative
-

page_text: sheets of drawings upon which are figures and reference numbers similar numbers
referring throughout the several views to the same thing or part.
The precise details in the arrangement of this my invention admit of modification
without departing from its nature, hence I have shown it in a general form, and also
in a modified form.
Fig. 1, is a sectional view of the base part of the stand pipe.
Fig. 2, is a sectional plan view of the lower parts, on line A-B Fig. 1.
Fig. 3, is a general elevation of the upper part of the stand pipe.
Fig. 4, is a sectional elevation showing several of the parts modified in
position.
Fig. 5, is a plan view of Fig. 4, on line C―D.
'
Fig. 6, is a part side view of Fig. 5, showing end view of certain automatic
mechanism.
Figs. 7 & 8, are general views of the entire stand pipe in its modified form.
I will first proceed to explain my invention as illustrated in Figs. 1, 2 & 3.
A rectangular cast iron box 1, is provided which is sunken or let into the ground,
level or thereabouts with the surface. Near the bottom is provided an inlet 2,
through which enters the main supply pipe 3, to which is attached a stop cock 4, so
that at any time the water may be here turned off to allow of removal, repairs, or
inspection of the rest of the fittings. Connected up to this stop cock 4, is a stop or
supply valve 5, having a vertical spindle 6, which passes upwards to near the cover
of the box, or in some instances may be carried to a higher point according to
requirements.
The spindle of this valve above the packing box has a screwthread 7, formed
thereon of any suitable pitch and size, which works in a screw nut 8, which latter is
carried upon the fixed bracket 9, so that upon the rotation of the said spindle 6,
the valve 5, is opened or closed. Immediately above this screw 7, a lever or arm 10,
is secured to the spindle, and to its outer end is connected the one end of a spiral
spring 11, the other end of the latter being attached to the bracket 9, or it may be
secured to the side of the box or other fixed part provided therein, in, such a
manner that its tendency is always to automatically close the valve 5. Instead
however of the spiral spring, any other form of a spring or its equivalent, as
hereinafter explained, may be used which will effect the same purpose. Also, in
some cases, instead of the screwthread upon the spindle and the fixed screwnut, an
equivalent cam like or inclined plane surface or surfaces, may be formed upon or
about the spindle, agreeing with and acted upon by corresponding surfaces upon the
lever so that upon the rotation of the spindle the valve may be opened or closed as
before.
In the large rectangular box cover 11*, is provided a recess 12, in which is
placed the valve spindle stuffing box or guide 13. At the upper end of the spindle
a square 14, or other shape is made to receive a turnkey 15. This recess is further
provided with a removable cover 16, (let in flush with the main cover) in which,
and immediately.over the valve spindle, is a hole through which the said turnkey
may be passed. The external shape of this key, and the hole through which it
passes are so shaped oval for instance, as that the key cannot be withdrawn except
when the valve is closed.
On the aforesaid large cover 11", there is also provided a recess or box part 17,
in which is situated a valve 18, of a somewhat peculiar construction, and which
serves a two fold purpose viz.: that of delivery, and also of draining off any surplus
water from the vertical delivery pipes. Or if preferred this valve may be situated
in the main box and below the ground line. This valve 18, is connected at its
underside, with the pipe 19, leading from the valve 5, and is further connected at
its upper side with the discharge pipe 20, which leads to the outlet 21. This
valve 18, is of the nonreturn type, and having its flap 22, preferably at an angle.
In the valve box and upon the upper side of the movable flap is an overflow or
outlet 23 and pipe .24, leading away to a drain or other escape. The face of the
outlet 23, is so arranged, that when the main stop valve is opened and the water
9

page_text: lifts the said nonreturn valve flap 23, the said valve upon its upper side closes this
said outlet, as seen in dotted lines in Fig. 1, and thus the water uninterfered
with, passes upwards through the discharge pipe 20, but upon the main valve.5,
being closed and the forward force of the water ceased, the nonreturn valve 22,
closes, and in so doing opens the overflow outlet 23, and permits the escape of the
water then standing in the discharge pipe and valve box, hence there will remain
no water in these parts to become frozen and so to impede the working of the
whole.
Connected with this overflow outlet is a turn cock 25, which, during the cold
weather is left open to permit of the automatic action of the double acting valve,
but which during the warmer weather (when no freezing is likely to occur) may be
closed, and thus prevent the overflow discharge of water from the discharge pipe.
Above this nonreturn valve is erected the usual cast iron column 26, within
which is concealed the discharge pipe 20, and from which the outlet 21, protrudes.
The main box 1, and the compartment in which is the nonreturn valve box 18, is
now filled with silicated cotton or other nonconducting material to more perfectly
prevent the freezing effect of extreme cold.
In Figs. 4, 5, 6, 7 & 8, I have as before intimated, shown this my invention
in a modified form, that is to say, I have shown how the main valve may be placed
horizontally instead of vertically so that the delivery pipes are connected to the
upper side of the valve which facilitates access and fitting, and in which also
instead of employing an automatic spring for operating the closing of the valve, I
employ its equivalent in the form of a weight. In this case the main box 27, is
- similar to that shown at 1, in Fig. 1; also its cover 28, is similar to cover 11ª,
shown in Fig. 1, and may or may not have a removable cover 16 as may be
desired. At 29, is the supply inlet to which in this case the main valve 30, is
connected direct. A shut off cock similar to 4, Fig. 1, may be here inserted if
desired, or it may be connected to the outside of the inlet 29. The valve spindle 31,
in this case as in Fig. 1, has a screwthread formed upon it at 32, which works in
a nut carried in the fixed bracket 33. Upon the end of the spindle 31, is secured
the weight 34, which hangs downward on the one side, and thereby keeps the
valve 37 automatically closed. At 35, however is connected the rod 36, which is
carried upward to near the top of the columnular stand 26, and there connected by
means of the lever 38, (shown in dotted lines) to the turning handle 39, carried in
bracket 40. It will be seen that by turning (rotating) this handle 39 the rod 36, is
raised or lowered and by means of which the weight 34, is similarly raised or
lowered which rotates the spindle 31, and thereby the valve 41 is opened or
closed.
The automatic draining of the water from the delivery pipe 41 is effected as
follows: Connected to the lower part of the said pipe is the tap 42, having the drain
pipe 43 leading therefrom to any convenient spot. Upon the spindle of this tap 42, is
carried the lever 44, which latter is connected at 45 to the weight 34, by means of
the link 46. Thus, each time the valve 37, is opened, (or what is the same thing,
the weight 34 is raised) the tap 42 is automatically closed, but whenever the valve 37,
is closed the said tap is automatically opened to allow of the water in the pipe 41,
to pass away. To save this waste of water in warm weather, an extra tap may be
fitted in the pipe 43, at any suitable point, which, during warm weather may be
shut, and opened during frosty weather. As before stated in reference to
Fig. 1, this box 27, would be finally filled with silicated cotton or other non-
conducting material to further secure the nonfreezing of the water in the fittings.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is':-
1. In stand pipes for water mains, and services, the combination with the main
supply valve and delivery pipes of the means employed for the automatic draining
or removal of the undischarged water from the delivery pipes above ground,

page_text: as herein described and illustrated in Figs. 1, 2 & 3, and also in the modification
shown in Figs. 4, 5 & 6.
2. The combination in stand pipes for water mains and services, with the inlet
pipe, main valve and delivery pipes, and the manipulating key or handle; of the
screwed part 7, working in fixed nut 8, and operated by means of the lever 10, and
spring 11, as herein described and illustrated in Figs. 1, 2 & 3.
3. The modified combination and arrangement with the main valve, supply and
delivery pipes, and manipulating key or hanale, of the weight 34, rod 36, and
lever 38, as herein described and illustrated in Figs. 4, 5 & 6.
4. The combination and arrangement of water stand pipe or service mechanism
in which in combination with the upper columnular stand and the delivery pipes,
the valves and their fittings are arranged and contained in a box beneath the
surface of the ground as herein described and illustrated in Figs. 1, 2 & 3, or in the
modification illustrated in Figs. 4, 5 & 6.
