JOHN MARION STUKES, OF SNYDER, TEXAS.
PUMP-STRAINER.
SPECIFICATION forming part of Letters Patent No. 661,591, dated November 13, 1900.
Application filed July 19, 1900. Serial No. 24,237. :No model.)To all w7om it may concern:
Be it known that I, JOHN MARION STUKES,
a citizen of the United States, residing at
Snyder, in the county of Scurry and State of
5 Texas, have invented a new and useful Pump-
Strainer, of which.the following is a specifica-
tion.
This invention relates to pumps in general,
and more particularly to that class designed
io for lifting liquids from wells, and it has spe-
cific reference to strainers for pumps, one ob-
ject of the invention being to provide a sim-
ple, cheap, and efficient construction which
will be effective in excluding sand and other
15 foreign matter which has the effect of locking
the pump-valve, wearing the movable parts,
and otherwise injuring or interfering with
the parts of the pump.
Further objects of the invention will be
20 evident from the following description.
In the drawings forming a portion of this
specification, and in which like numerals of
reference indicate similar parts in the several
views, Figure 1 is an elevation showing the
25 lower end of a pump-barrel and illustrating
the strainer attached thereto. Fig. 2 is a cen-
tral vertical section of the strainer, the upper
end of the tubular core being shown in eleva-
tion. Fig. 3 is a transverse section taken
30 through the strainer and its tubular core.
Referring now to the drawings, the strainer
comprises a tubular co 5, the upper end of
which is threaded for engagement with the
reducing-coupling 6 at the lower end of the
35 pump-barrel 7, while the lower end of the core
is also threaded for engagement of a cap 8,
which acts to close the pump-strainer at its
lower end.
The strainer proper consists of a helical
40 winding of wire about the core and spaced
therefrom, and this wire is wound upon spac-
ing bars or bridges. In the drawings the spac-
ing bars are shown at.l0 and have their ends
bent at right angles to the central portions of
45 the bars and in the same direction, these
spacing-bars being disposed upon the outer
surface of the 'tubular core and extending
longitudinally thereof, the ends of the bars
being engaged with perforations 11 in the
50 core, said ends, as shown at 12, projecting
into the core to an extent sufficient to pre-vent accidental displacement of the bars
which are spaced equidistant about the pe-
riphery of the co-e.
A wire 15, of brass or other suitable non- 55
corrosive material, has one end engaged in a
perforation 16 below the lower ends of the
bars 10, and above this perforation the wire
is wound upon the core and then up and over
the ends of. the bars 10, the winding being 6o
then continued round and round the core and
over the bars until the bars are completely
incased in a helix of wire. The winding of
the wire is continued over and beyond the
upper ends of the bars 10 and upon the core 65
5, and the upper end of the wire is engaged
with a perforation 17 in the core. The core
has thus an encircling helix of wire extend-
ing throughout a portion of its length and
inclosing an interspace or chamber between 70
it and the core, and this chamber commu-
nicates with the interior of the core through
perforations 19, formed in the core. The
several convolutions of the helix are of course
separated by slight interspaces, which per- 75
mit ingress of water, but prevent passage of
sand and other large particles into the cham-
ber between the helix and core, and in or-
der to hold the wire in proper position upon
the spacing-bars they are soldered above the 8o
bars. Solder is also preferably applied to
the wire at the ends of the spacing-bars to
hold the convolutions thereof against the in-
turned ends of the bars. With this construc-
tion it will be seen that there is provided an 85
effective strainer and one that is simple,
cheap, and durable, and, furthermore, that in
the manufacture of the strainer the spacing
of the convolutions of the helix may be va-
ried as desired to secure the best results un- go
der different conditions.
It will be understood that in practice va-
rious modifications of the specific construc-
tion shown may be made and that any suit-
able materials and proportions may be used 95
for the various parts without departing from
the spirit of the-invention.
What is claimed is-
1. A strainer for pumps comprising a hol-
low core,spacing-bars disposed longitudinally- too
of the core and upon its outer surface, a wire
helix wound over the spacing-bars and in-
