As shown in Fig. 1, the wire of which
the strainer is made is triangular in cross
section, and this is the preferred shape; but
if desired the wire may be circular, semi-
5 cylindrical, or diamond shaped, in cross
section.
The extremities of the strainer wire are
secured, in any preferred manner, to the
pipe, as by soldering thereto.
10 A screen, constructed as described and
shown, will be found to be very strong and
durable, so as to allow hard rotation, with-
out disarrangement of the spacers or the
strainer wires; as well as simple and com-
15 paratively inexpensive to construct, and
easily repaired in case of injury to any of its
parts.
What I claim is:
1. In a well screen a perforated strainer
20 pipe provided with a plurality of longitu-
dinal grooves therein, spacers designed to
be partially embedded in said grooves for
their entire length, the outer portions of
which project from said grooves, and are
25 provided with notches, said notches forminga spiraled groove, and a strainer held in
position by the spiraled groove.
2. In a well screen a perforated strainer
pipe provided with a plurality of longitudi-
nal grooves therein, spaces designed to be 30
partially embedded in said grooves for their
entire length, the outer portions of which
project from said grooves and are provided
with sharp edges, and a strainer held in
position by the spacers. 35
3. In a well screen, a perforated strainer
pipe provided with a plurality of longitudi-
nal grooves therein, spacers designed to be
partially embedded in said grooves for their
entire length, the outer portions of which 40
project from said grooves, and a strainer
held in position by the spacers.
In testimony whereof I have signed my
name to this specification in the presence
of two subscribing witnesses.
