ANDREW P. MORRIS, OF SNYDER, TEXAS.
SUBMERGED DOUBLE-ACTING PUMP.Specification of Letters Patent. Patented Nov. 15, 1910.
Application filed May 21, 1910. Serial No. 562,778.To all whom it may concern:
Be it known that I, ANDREw P. MoRRIs, a
citizen of the United States, residing at
Snyder, in the county of Scurry and State
5 of Texas, have invented certain new and
useful Improvements in Submerged Double-
Acting Pumps, of which the following is a
specification.
My invention relates to pumps and more
10 particularly to double acting pumps, and
the object is to provide pumps with which a
practically continuous flow of water or other
liquid may be had, to provide a pump from
which the fixtures can be removed without
15 disturbing the pump barrel, to provide the
pumps with a spool for the sliding piston
head so that the piston head will not be
locked by sand or gravel, and to provide
the pumps with intake valves for the down
20 stroke of the piston located on the outside
of the pump barrel so that the valves will
not interfere with the removal of the fix-
tures.
Other objects and advantages will be fully
25 explained in the following description and
the invention will be more particularly
pointed out in the claims.
Reference is had to the accompanying
drawings which form a part of this applica-
30 tion.
Figure 1 is a vertical section of the pump
with the piston on the down stroke. Fig. 2
is a vertical section of the same with the
piston on the upstroke. Fig. 3 is a hori-
35 zontal section of the spool which carries the
piston-head. Fig. 4 is a vertical section of.
one of the pocket valves located on the out-
side of the pump barrel. Fig. 5 is a vertical
section of a portion of the pump barrel and
40 tubular piston rod, showing a variation in
the piston head and the intake valve for the
tubular piston rod.
Similar characters of reference are used
to indicate the same parts throughout the
45 several views.
The pump is provided with a barrel ,1, a
sleeve 2 screwed on the barrel, and a lead
pipe 3 screwed into the sleeve 2. An intake
valve 4 is provided at the bottom of the
50 barrel 1. The sleeve 2 is provided with in-
take valves 5 which close the intake ports
or inlets into the upper part of the barrel.
A cap 6 closes the passage between the pump
barrel and the lead pipe 3 or discharge por-
55 tion except through the tubular piston rodhereinafter explained. The piston rod 7
moves through a perforation in the cap 6
and through the nipple 8 on the cap. A
stuffing box or gland is provided in the fol-
lowing manner. A leather flanged sleeve 9 o
is mounted in the nipple 8 and the flange
thereof rests on top of the nipple. A cap 10
is perforated and screwed on the nipple 8.
A spool 11 is attached to the piston rod 7
by screwing a flanged coupling 12 on the 65
lower end of the rod 7 and then screwing
the spool 11 into the coupling 12. The spoo
11 has an annular shoulder 13 and a leather
washer 14 is caught between the flange 15
and the shoulder 13 and forms a seat for the 70
piston head 16 above the piston head. The
spool 11 consists of an upper ring 17 and a
lower ring 18 connected by a plurality of
bars 19 which may be integral with the two
rings. The ring 18 is beveled between the 75
bars 19 so that there will be as little resist-
ance to the inward flow of water as possible.
A flanged plug 20 is screwed into the ring
18. A leather washer 21 is caught between
the ring 18 and the flange 22 and this washer 80
forms a lower seat for the piston head.
Provision is made for the removal of the
piston rod and piston and the cap 6 with-
out disturbing the barrel 1, sleeve 2, and
lead pipe 3. The cap.6 has left threads and 85
the cap of the stuffing box has upwardly
projecting lugs 23 and the piston rod 7 has
pins or bits 24 for engaging the lugs 23.
The sections of the sucker rod are provided
with right threads, consequently when the 90
sucker rod is used to unscrew the cap 6 the
sections of the sucker rod will not be un-
screwed. The bits 24 will engage the lugs
23 and the cap 6 may be unscrewed from the
sleeve 2. The nipple 8 and cap 10 will also 95
have right threads. When the cap 6 is re-
leased, it and the piston, and piston rod can
all be removed from the pump barrel and
lead pipe without disturbing the barrel or
lead pipe or sleeve 2. The pocket intake 100
valves 5 are located on the outside of the
sleeve 2 and below the large part of the
sleeve in order not to interfere with the in-
sertion of the sleeve in the well. The valves
are not in the way of removal of the pis- 1ob
ton. Pockets 25 are provided with nipples 26
which are screwed into the sleeve 2. Caps
26' are screwed on the pockets 25 and the in-
let ports for the valves are made in the caps
26'. The valves 27 close the ports 28 and 110975,781.
