LEE J. BLACK, OF BEAUMONT, TEXAS.
PUMP.Specification of Letters Patent.
Patented Oct. 24,1916.
Application filed October 21, 1915. Serial No. 57,063.
To all whom it may concern:
Be it known that I, LEE J. BLACK, .a citi-
zen of the United States, residing at Beau-
mont, in the county of Jefferson and State
5 of Texas, have invented certain new and
useful Improvements in Pumps, of which
the following is a specification.
This invention relates more particularly
to the valve chests of pumps, and its object
10 is to provide a pump having a valve chest
- which is formed of a single casting remova-
bly mounted on the pump cylinder, and
carrying all the valves of the pump, thereby
obtaining certain advantages as will be
15 pointed out hereinafter.
The invention also has for its object to
provide. a valve chest of novel construction
and improved means for securing the same
to the pump cylinder.
20 In order that the invention may be bet-
ter understood, reference is.had to the ac-
companying drawings, in which-
Figure 1 is an elevation of .the pump
partly in section on the line 1-1 of Fig. 3;
25 Fig. 2 is a cross-section of the valve chest
on the line 2-2 of Fig. 3; Fig. 3 is a plan
view, with parts in section, on the line
3-3 of Fig. 2, and Fig. 4 is a horizontal
section on the line 4-4 of Fig. 2.
30 Referring specifically to the drawings, 10
denotes the cylinder of the pump, the same
containing a liner 11 in which the pump
plunger 12 reciprocates. The pump illus-
trated is a steam pump, the steam engine
65 cylinder being shown at 13, and the piston
of the latter being directly connected to the
pump plunger rod 14. It is to be under-
stood, however, that the invention is not
limited to this type of pumps, as, any other
40 suitable power and driving connections may
be employed.
The pump cylinder 10 is provided with a
valve chest 15 which carries all the valves
of the pump and is entirely separate from
45 the pump cylinder and removably connected
thereto. The pump cylinder is a single cast-
ing which is bolted to the cylinder over the
end ports 16 and 17 thereof. The base of
the valve chest has an encircling outstand-
5o ing flange 18 which matches a flange 19 on
the cylinder. Bolts 20 passing through the
flanges 18 and 19 secure the valve chest to
the cylinder. Additional fastening means
for the valve. chest are also provided, the
55 same comprising a row of bolts indicated at
21,: 22, 23; 24 and 25, respectively, the sameprojecting from the base of the valve chest
and being here threaded to screw into the
cylinder wall. The outer ends of the last-
mentioned bolts are threaded to receive nuts co
26, and the latter, with the exception of the
nut of the bolt 21, also serve to secure
clamps 27 which hold down the valve cov-
ers 28 to be presently described.
The inlet chamber 29 of the cylinder 10 is e.
between the end ports 16 and,17 and has the
usual intake. The valve chest 15 seats over
this chamber.
The valve chest 15 has a top discharge
chamber 30, provided with an outlet 31. 70
Beneath the discharge chamber, and sepa-
rated therefrom by a partition 32, 4re four
inlet chambers 33, 34, 35, and 36, respec-
tively, separated from each other by a trans-
verse partition 37 and a longitudinal parti- 7
tion 38 which cross and extend between the
bottom wall 39 of the valve chest and the
partition 32, and also between the side walls
of the valve chest. These walls and. parti-
tions are all cast integral with the valve
chest.
The chambers 33 and 35 have inlet ports
40 which are in communication with the
port 16, and the chambers 34 and 36 have
inlet ports 41 which are in communication s8
with the port 17.
That portion of the bottom wall 39 of the
valve chest which se-ats over the inlet cham-
ber 29 of the cylinder 10 has valved inlet
ports 42 establishing communication be- 90
tween said chamber and the respective inlet
chambers 33, 34, 35 and 36. The valve of
the chamber 33 is shown at 43, the valve of
the chamber 34 at 44, the valve of the cham-
ber 35 at 45 and the valve of the chamber 95
36 at 46.
In the partition 32 are valved ports 47
providing outlets for the inlet chambers 33,
34, 35 and 36 and establishing communica-
tion between said chambers and the dis- 100
charge chamber 30. The outlet valve of the-
chamber 33 is shown at 48, the valve of the
chamber 34 at 49, the valve of the chamber
35 at .50, and the valve of the chamber 36
at 51. 105
In operation, when the plunger 12 is trav-
eling to the right, the pump takes in water
from the inlet chamber 29 and through the
valves. 43 and 45, and discharges into the
chamber 30 through the valves .49 and 51. 110
On the opposite stroke.of the plunger, the
pump takes in water through the valves 441,202,153.
