PETER JEROME LEITHAUSER, OF CLARENDON, TEXAS.
PUMP.
SPECIFICATION forming part of Letters Patent No. 776,922, dated December 6, 1904.
Application filed May 4, 1904. Serial No. 206,353, (No model,)TO (i6 wh 7 iJV77, 7t'bai777// e0r7r77.'
Be it known that I, PETER JEROME LEIT-
HAUSER, a citizen of the United States, and a
resident of Clarendon, in the county of Donley
5 and State of Texas, have invented a new and
Improved Pump, of which the following is a
full, clear, and exact description.
This invention relates particularly to im-
provements in pumps for raising water from
in deep wells, an object being to provide a pump
of this character with novel means for center-
ing and yieldingly holding the pump at any
desired position in a well-casing and also to
provide a simple means whereby the working
15 parts of the pump may be readily raised from
- the well when it is necessary to make repairs.
Other objects of the invention will appear
in the general description.
I will describe a pump embodying my in-
20 vention and then point out the novel features
in the appended claims.
Reference is to be had to the accompanying
drawings, forming a part of this specification,
in which similar characters of reference indi-
25 cate corresponding parts in all the figures.
Figure 1 is an elevation, partly in section,
of a pump embodying my invention. Fig. 2
is a side view of the piston and valve mech-
anism employed. Fig. 3 is a longitudinal see-
30 tion thereof. Fig. 4 is a section on the line
4 4 of Fig. 3. Fig. 5 is a bottom view of the
construction shown in Fig. 2. Fig. 6 is a side
view of the valve employed. Fig. 7 shows a
spacing-ring employed. Fig. 8 indicates the
35 valve-casing, and Figs. 9, 10, and 11 indicate
the positions of parts when inserting or re-
moving the pump.
Referring to the drawings, 5 designates a
well-casing designed to be secured in the well
40 in any suitable manner. Extended downward
in the casing and movable vertically therein
is a tubular pump-rod 6, which at the upper
end is connected to any suitable actuating
mechanism. It is here shown as having a
45 bearing in a bracket 7, attached to a standard
8 on the well-platform, and it is connected to
a hand-lever 9, mounted to swing on the stand-
ard by means of links 10.
Attached to the lower end of the tubular
50 pump-rod 6 is a valve-casing 11, with the lowerend of which an extension-tube12-has screw-
thread connection. The upper end of the tube
12 forms a seat 13 for the spool-like valve
14, the upper flange - like end 15 of which is
provided with perforations 16 to permit of 55
the upward flow of water. The valve-casing
11 is surrounded by a shell 17,.which is wa-
ter-tight.. Mounted on the extension-tube 12
are the suction devices, consisting of leather
cups 18, held and clamped on the extension 6o
by means of clamping-rings 19. The valve
and suction devices operate in a tube 20, the
upper end of which is removably connected
to a pipe-section 21 and through which the
pump-rod passes, and on this pipe-section 21 65
are secured springs 22, which engage with the
inner surface of the casing 5 and serve to cen-
ter the parts and also to hold the parts yield-
ingly in place. As here shown, the upper
ends of these springs are bolted to a collar 23 70
on the pipe-section 21, and the lower ends are
bolted to a collar 24, also secured to said pipe-
section. Secured to the pipe-section 21 b.y
means of a coupling 25 is a dog-carrying sec-
tion 26. The dogs carried by the section 26 75
consist of upwardly-extended spring-rods 27,
the upper ends of which are turned outward
at 31 to form hooks to engage against the in-
ner surface of the casing 5 and to serve an-
other purpose, as will be hereinafter described. 8o
The rods 27 are secured to the section 26
by means of a ring 28 near the upper end of
the section and a collar 29 near the lower
end, secured by set-bolts 30. The hook ends
31 of the rods 27 are designed to be engaged 85
by a ring 32, attached to arms 33, depending
from a lifting-sleeve 34, which of course sur-
rounds the pump-rod, and has removably en-
gaged with its upper end a cap 35, having an
opening through which the pump-rod may 90
loosely slide.
In the operation when the pump is to be
inserted in the casing the parts are.to be low-
ered or pushed downward by forcing down-
ward the pump-rod 6, to which new sections 95
may be connected to get the required depth.
After the pump is placed at the desired posi-
tion a tubular striker 36 is to be lowered
around the pump-rod. This tubular striker
is provided with a bail 37, from which a rope 100No. 776, 922.
