Improvements in Force and Lift Pumps.
I, CHARLES GARFIELD HAYES, Farmer, of Tiskilwa, in the County of Bureau,
and State of Illinois, United States of America, do hereby declare the nature of
this Invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
-
My Invention relates to improvements in force and lift pumps, and the object is
to provide a simple, efficient, and durable duplex pump of this class. To this end the
novelty consists in the construction, combination and arrangement of the same as
will be hereinafter more fully described and particularly pointed out in the claim.
In the accompanying drawing the same reference characters indicate the same
parts of the invention.
Figure 1 is a side elevation of my improved duplex pump;
Fig. 2 is a vertical section of the duplex discharge pipe; and
Figure 3 is a perspective view of the handle supporting bracket.
1 represents a tubular standard adjustably secured in the base flange 2 by set-
screws 3-3, and its lower end is secured by screw-threads in the upper face of a
hollow rectangular case or box 4.
5 represents a short section of pipe connecting the lower face of said case 4 with
the tubular yoke 6, the lower ends of which are connected by parallel pipes 7-71
to the upper ends of the pump cylinders 8-9. Two parallel pipes 10-101 extend
from the lower ends of the cylinders 8 and 9 and connect with the upper end of the
Y fitting 12, and from the lower end thereof a suction pipe 13 extends below the
level of the water in the well.
The upper end of the standard 1 is provided with an air-tight cap bracket 14,
having vertical integral parallel arms 15-15, which support a horizontal bolt 16,
on which is fulcrumed a lever 17, the outer ends of which are provided with a
series of transverse orifices to receive the upper ends of the connecting rods
18-181, which extend downward through the stuffing boxes 19-191 and the
parallel pipes 7-71, and into the cylinders 8 and 9, where their ends are provided
with the usual pistons, as shown. 20-20¹ represent the usual foot valves in the
bottom of the cylinder.
The lever 17 is provided at each end with a socket 21, in one end of which is
shown the wooden handle 22, detachably secured in said socket by the usual bolts 23.
This handle may be secured in the socket at either end of the lever to conveniently
operate the pump.
24 represents an integral eye on the lever 17 to which the lower end of the
connecting rod (not shown) of a windmill may be attached, for automatically
operating the pump. 25 represents the discharge pipe, its lower end com-
municating with the case 4 and extending upward parallel with the standard to
which it is secured, by a clamp 26, from which a suitable brace 27 extends
diagonally to the ground or floor. The upper end of the discharge pipe 25
terminates in a goose-neck spout 28, through which the water is discharged when
obtained at the pump.
29 represents an elbow communicating with and extending laterally from the

page_text: case 4, and to its outer end is connected a service pipe (not shown) which extends
to a tank located at a suitable point to distribute the water about the premises,
as desired, for household use, irrigation, and the like.
30 represents a hand-wheel secured to the upper end of a valve-rod 31, passing
through the stuffing-box and extending downwardly through the discharge
pipe 25, and terminating in the casing 4. The upper portion of said valve-rod 31
is formed with a threaded section 33, which engages a threaded orifice in a cross
bar 34 in the goose-neck, as shown.
The lower end of the valve-rod 31 is screw-threaded, and is provided with a
horizontal disk valve 35, secured in place by the washers 36-36 and nuts 37-37,
and according as it is manipulated by the rod 31 and hand-wheel 30, it will close
the opening in the lower end of the discharge pipe 25, and allow the water to flow
through the elbow 29 to the service pipe, or by closing the communicating orifice
in the contiguous end of the elbow, cause the water to flow through the discharge
pipe 25 and goose-neck 28.
The tubular standard 1 being closed at its upper end by the cap-bracket 14,
forms an air chamber, which tends to equalise the pressure in the yoke 6, and
consequently deliver a continuous stream at the discharge end of the pump.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
A duplex pump comprising the tubular standard 1, the cap-bracket 14 secured
to the upper end thereof and provided with the integral vertical parallel arms
15-15, the case or box 4, secured to the lower end of said standard, the three-way
yoke 6 provided with the stuffing-boxes 19-191, the vertical pipe 5' connecting
said case 4 and yoke 6, the pump cylinders 8 and 9, the parallel pipes 7-7 con
necting said cylinders independently to said yoke, the Y-fitting 12, the parallel
pipes 10-10, connecting the lower ends of said cylinders with said fitting and the
suction pipe 13 depending from said fitting, in combination with the elbow 29 and
the discharge pipe 25 communicating with the case 4, a horizontal disk valve
mounted in said case and adapted to alternately close the contiguous end of the
elbow or discharge pipe, means substantially as described for operating said valve,
the lever 17 fulcrumed in the cap-bracket 14 and provided with the detachable
handle 22, and the connecting rods 18-18¹ connecting said lever with the pistons
in the cylinders 8-9, as and for the purpose set forth.
Dated this 18th day of May. 1897.
