the delivery pipe or riser 10 is supported.
in any suitable manner upon the head 9,
and this pipe is of sufficient diameter so
that the riser or delivery pipe 10 may be
5 easily turned within the protector pipe.
The riser is also preferably provided with
an annular shield 14 which extends over
and down around the upper edges of the
protector pipe 13. This is for a purpose to
10 be later described.
The lower end of the valve stein 7 is
reduced as at 15. This reduced portion is
screw threaded for engagement with a nut
16. Means must be provided for limiting
15 the movement of the valve stem 7 relative
to the valve casing 4 so that when the valve
stem is rotated to one position the ports
5 and 8 will register and that wIhen rotated
to another position, the port 8 will register
20 with the drainage port 6. For this purpose
I have cut away the lower end of the stem
7 as at 17 so as to form a flat side or face,
and form the lower end of the valve casing
with an arcuate recess 18. The ends of this
25 recess are defined by shoulders 19. Dis-
posed between the nut 16 and the lower end
of the valve casing 4 is the washer 20. This
washer fits upon the lower end of the valve
stem, and the interior bore of the washer
-o has a flat face 21 which fits against the flat
face 17 on the lower end of the valve stem
so that though the washer may be with-
drawn, it must turn with the valve stem.
Carried upon the washer is the upwardly
35 projecting lug 22 which projects into the
recess 18 and which contacts with one or the
other of the shoulders when the valve is
turned to one or the other of its positions.
The object of this construction last described
40 is to provide a construction in which dirt
and other foreign matter will be prevented
from accumulating in the recess 18. It will
be seen that the recess 18 is disposed on the
inner face of the valve casing and that the
45 washer 20 has the same diameter as the
exterior diameter of the valve casing, and
that therefore the washer projects beyond
the recess 18 and thoroughly protects - the
same, forming a cap for the recess pre-
50 venting the entrance of dirt. The washer
20 is held in snug engagement with the
lower end of the valve casing by means of
the nut 16 which may be turned up to any
desired extent. ' This nut 16 of course acts
55 to draw the valve stem 7 down into snug
and water-tight engagement with the in-
terior face of the valve casing 4.
In order to prevent dirt and other foreign
matter from impeding the easy rotation of
60 the riser or delivery pipe 10, I have provided
the tubular protector pipe 13 which extends
up to a point above the ground line A-A.
The upper open end of this protector pipe
13 is covered by the shield 14 which pre-
65 vents dirt or dust from collecting betweenthe pipes 13 and 10, and also prevents the
entrance of rain. It will be seen that this
construction provides for. a very easy rota-
tion of the riser 10 and prevents the fric-
tional resistance of the earth which is a
packed around the riser from impeding its
rotation. In this form of my invention
water flows along the main 2 and, if the
valve be in its opened position, through
the ports 5 and 8 into the hollow interior of 7
the valve stem 7, thence up the riser 10 and
is delivered at the bib or faucet. When it
is desired to close the valve, the bib or fau-
cet is used as a handle for rotating the riser
10 and the valve stem 7, thus shifting the 80
port 8 out of register with the port 5, and
upon a complete rotation of the valve stem
shifting the port 8 into register with the
port 6. When in registry with the port 6,
all the water contained within the riser 85
and the valve will flow out through the
drainage port and thus the valve will be
protected from freezing up. It is to be par-
ticularly noted that there is no obstruction
to the constant flow of water through the 90
main 2, whether the valve be open or closed,
and that this construction is particularly
adapted to be used where a series of risers
or delivery pipes are connected to one main
pipe.-95
Another form of my invention is illus-
trated in Fig. 6 wherein 23 designates the
pipes of a main and 24 a T located therein,
this T being provided with an outwardly
projecting branch 25 as usual. This branch 100
may be either interiorly or exteriorly screw
threaded. The valve casing 26 is cylindrical
and tapered from one end to the other and
is. open at both ends. It is provided with
an inlet port 27 and from this inlet port ex- 105
tends a curved branch 28, screw threaded at
its end fpr engagement with the branch 25.
Disposed within the valve casing 26 is the
hollow tapered valve 29 of the same charac-
ter as previously described. This valve is 110
provided with the inlet port 30 which cor-
responds to the port 8 in the previous con-
struction. The port 30 as the valve is ro-
tated is adapted in one position of the valve
to register with the port 27, and in the other 115
position of the valve to register with a
drainage port 31, preferably located 90c
from the port 27. The upper end of the
valve stem is provided with a many sided
head 32 corresponding to the many sided 120
head 9 previously described, this head being
interiorly screw threaded for engagement
with the riser 33, this riser being provided
with a bib 34, the riser being surrounded
by a protector pipe and having a shield for 125
the upper end of the same precisely as previ-
ously described. The lower end of the valve
casing is provided with an arcuate recess 36
corresponding to the recess 18 previously de-
scribed, and interposed between the tighten- 1303
