JOE R. COOKE AND JOHN T. COOPER, OF ALVARADO, TEXAS.
IRRIGATION-PIPE.Specification of Letters Patent.
Patented Oct. 27,1914.
Application filed September 5, 1911. Serial No. 647,480.
To all whom it may concern:
Be it known that we, Join R. COOKE and
JoHN T. COOPER, citizens of the United
States, residing at Alvarado, in the county
5 of Johnson and State of Texas, have in-
vented certain new and useful Improvements
in Irrigation-Pipes, of which the following
is a specification.
Our invention relates to an improved irri-
10 gation pipe which is to be used in connection
with a sub-irrigation. system, and the prin-
cipal object is to so construct the pipe that
earth will be prevented from packing about
the pipe to such an extent as to clog the
15 openings in the pipe through which water
passes.
Another object is to provide a pipe which
can be cheaply manufactured and which will
be strong, durable, simple, and efficient, and
20 not likely to get out of working order..
This invention is illustrated in the accom-
panyng drawings wherein-
Figure 1 is a plan view of a sub-irrigation
system with which the improved pipe may
25 be used; Fig. 2 is a sectional view taken
along the line x-x in Fig. 1; Fig. 3 is an
enlarged sectional view through one of the
irrigation pipes shown in Fig. 1.
The construction of the improved irriga-
30 tion pipe is clearly disclosed in Figs. 2 and
3 of the accompanying drawings, and in Fig.
1 there is shown a system with which the
improved pipe can be used.
Referring to Fig. 1, the numeral A indi-
35 cates a supply tank which is filled by means
of a supply pipe B. An outlet pipe C leads
from the lower end portion of the tank A,
and is provided with a valve D so that the
flow of water through the pipe C into the
40 distributing mains E may be controlled.
Each of these mains E is provided with a
valve F to permit the mains to be separately
controlled, and thus the water permitted
to flow through one of the mains into the
45 branch pipes G or HI without the water flow-
ing through the second main. Referring
more particularly to Figs. 2 and 3, it will
be seen that each of these branch pipes is
provided with a flat upper face and with
50 straight side' walls which merge into acurved base. By having the upper face flat
and relatively wide, the weight of the earth
in which the branch pipes are embedded is
disposed upon the upper faces of the .pipes.
Since the upper faces of the pipes are rela- 55
tively wide and extend beyond the points
at which the lower faces of the pipes rest,
the earth will be prevented from packing
about the bottom of the pipes and clogging
the apertures J which are formed in the o
pipes, as shown in Fig. 3. The water which
flows through the pipes (- can therefore
freely drain through the apertures J and
saturate the earth, thus irrigating the field.
These pipes may be formed of any suitable 65
material such as metal, cement, or any other
desired material according to the wishes of.
the person manufacturing the pipes.
We have therefore provided a pipe which
is so constructed that the apertures G are 70
not liable to be clogged up, thus preventing
the water in the pipes from passing out of
the same into the field. It will also be noted
that the pipe is so constructed that it may be
cheaply manufactured and readily set up. 75
It will also be noted that this pipe will not
be liable to quickly get out of order, and that
therefore, it will not be necessary to be con-
tinually making repairs to the irrigating
system. 80
Having thus described the improved pipe,
what is claimed is:
A one piece irrigation, pipe having a rela-
tively wide flat upper face and having
straight side faces merging into a rounded 85
bottom, the pipe being provided with a lon-
gitudinally-extending conducting bore and
with outlet openings formed in-tie side of
the curved bottom of said pipe and extend-
ing parallel to the straight side faces of 90
said pipe.
In testimony whereof we have signed our
names to this specification in the presence of
two subscribing witnesses.
