Improvements in Pumps.
We KARL AUGUST KLOSE and WILLIAM KOUNTZ SEWARD, Manufacturers,
both of Butte City, in the State of Montana, 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:-
This invention has relations to improvements in pumps, and its novelty and
advantages will appear from the following description and claims, when taken in
connection with the annexed drawing, in which:
Fig. 1, is a front elevation, partly in section, of a double acting pump.constructed
according to our improvements.
Fig. 2, is a horizontal sectional view taken.in the plane indicated by the dotted
line a,, of Fig. 1.
Fig. 3, is an inverted plan view of one of the yokes or valve casings.
Fig. 4, is a vertical, longitudinal sectional view of the coupling for the water
tubes mounted on the barrels or cylinders.
Fig. 5, is a side view of the same, with parts broken away, and,
Fig. 6, shows a modified construction illustrating my improvements as applied. to
a single acting pump.
An important desideratum in this class of machines has been to provide, a pump
which will work. effectively at the start, after remaining idle for a long period, and
which owing to the valves becoming dry must be saturated or well moistened to
get the parts to work tightly so as to lift or force liquid. To do this. effectively
and reduce the cost of the pump is the main object of our invention.
Referring by: letters to the. drawings:
A, indicates a frame which may comprise standards or other suitable supports
for a horizontally disposed rotatable shaft B, having loops or cranks a, disposed at
right angles in opposite directions, and this shaft while shown with a wheel b,
carrying a handle for rotating the shaft, it is obvious that the wheel may be
adapted to receive a belt or gear by which suitable power may be employed.
Depending from these cranks a, are rods c, which are connected at their opposite
or lower ends with plunger.rods C, as shown.
D, indicates the body of the pump which is shown in Fig. 1, as of the twin type
or double acting construction. and in Fig. 6, as of the single acting type. The
body, when a double acting pump is used is formed in one piece having the
barrels d, d, provided at a suitable point in their lengths and diametrically opposite
points with exterior hook lugs e, e. These barrels are covered with a plate E,
which is provided with central, vertical passages f, designed to receive from the
barrels, and said plate is also provided with peripheral projections. having eyes g,
to receive vertical bolts h; these bolts have eyes at their lower ends to receive the
book lugs e, and are threaded at their upper ends to receive.nuts or other suitable
devices, whereby the cap plate may be drawn tightly down upon the cylinders.
The lower ends of the barrel or barrels are closed by a plate F, having, an
upwardly directed marginal flange which is internally threaded to engage the
external threads. at the lower end of the barrels as shown. This plate is also
provided with a central inlet aperture j, which is screw tapped to receive, a

page_text: pipe G, and within this aperture may be a guard k, as shown. At the upper end
of this aperture is formed a seat for a ball valve H, and which valve is formed of
solid rubber.
I, indicates a yoke or frame for the lower valve. This frame comprises a ring
or annulus l, which is secured in position by being placed between the lower end
of the barrel or barrels and the lower plate F, and rising from this ring are
branches m, which meet or cross each other horizontally at right angles; a packing
ring being interposed as shown. This yoke is of a sufficient height to allow the
ball valve to rise and properly seat itself.
In a double cylinder pump, this valve is placed beneath the division wall n, and
said wall is cut away at a suitable altitude as shown at P, so as to afford a passage
into each barrel or cylinder, while in a single acting pump the valve is placed
directly beneath the plunger head as shown in Fig. 6, of the drawings.
J, indicates the plunger heads having a central aperture q, and a peripheral
groove r, within which grooves are placed metallic rings s, designed to tightly
pack or wipe the barrels.
Rising from each annular head is a yoke or frame t, of a skeleton form and to
which the plunger rods C, are suitably connected. These skeleton frames are
secured to the plunger heads by bolts u, which are screw-threaded at their lower
ends and pass through tubes v, depending from said yokes or frames and take into
threaded apertures in the rings or heads.
The passages f, of the top plate E, are screw-tapped and receive tubes K, which
in double acting pumps are in turn connected with short tubes L, by means of a
union M, and these latter tubes are in turn connected with pipes or tubes N, which
are covered with a cap P, having a suitable packing and an aperture for the
passage of the plunger rods C. These tubes N, are each provided with an aligned
aperture w, and receive the opposite threaded ends of a section Q. This section Q,
is of a peculiar construction, being designed to receive from both barrels or
cylinders and discharge through a lateral aperture R, into a pipe S, which may
have a lower goose-neck T, and an upper goose-neck U, or pipe of other suitable
character.
The section Q, has a horizontal passage V, leading from each end to suitable
points where they meet upper branches W, having suitable sents to receive ball
valves X, which are also composed of solid rubber. These passages W, terminate
in screw-tapped apertures which are closed by screw caps Y, whereby ready access
may be had to the valves and said passages intersect a horizontal passage Z, which
leads to the discharge aperture communicating with the outlet pipe S.
In applying our improvements to a single acting pump, we dispense with the
eye bolts or rods depending from the top plate and also the lugs on the barrels
or cylinders as well as the series of sections of pipe or tubing above the top
plate.
From the foregoing description taken in conjunction with the accompanying
drawing, the operation of our invention will be obvious. It will be seen that we
have a pump which is very effective in operation, not likely to get out of order,
and should any of the parts become warm or injured they can be readily removed
and replaced by others."
In the practical operation of the construction shown in Figure 1, when the
shaft B, is rotated and the plungers J, are reciprocated it will be observed that
when one plunger, the right hand one for instance, is moving downwardly, the
other plunger is moving upwardly. Consequently the left hand plunger will
create a suction which will lift and hold the valve H, above its seat and will also
litt water from the source of supply into the barrels d, while the right hand
plunger will force the water up through its aperture q, and past its valve and out
of the pump. When the left hand plunger is moving downwardly and the right
band one upwardly, the right hand plunger will lift the water into the barrels
while the left hand one will force it up through its aperture q, past its valve and
out of the pump. It will be appreciated that inasmuch as there is a free passage

page_text: for the water through the downwardly moving plunger which subjects such water
to pressure, the said downwardly moving plunger will not tend to force and hold
the valve H, against its seat.
Having now particularly described and ascertained the nature of our said iuven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The pump barrels having the bottom closing plate provided with the inlet
aperture and the vertical marginal internally threaded flange, said barrels having
the division wall cut away at its lower end as shown, in combination with the
valve yoke I, composed of the ring or annulus secured between said plate and the
lower edge of the barrels, and a skeleton frame rising therefrom, and the ball valve
arranged over the inlet and within said yoke, substantially as specified.
2. In a pump, the combination with the two barrel cylinders having the central
division wall cut away at its lower end, the base plate having the inlet aperture,
the valve yoke or frame secured over said aperture and the rubber ball valve
arranged in said yoke, the plungers carrying ball valves and having yokes for said
valves, the top plate for the barrels, the tubes rising therefrom, the section
connecting said tubes and having the endwise passages, and ball valves therein,
and the lateral passage to receive a discharge pipe, substantially as specified.
