Improvements in Pumps.
We, JACOB JACOBSEN, of Lead City, in the County of Lawrence and State of
South Dakota, United States of America, Miner, and KASPER TIMON, of Lead
City, in the County of Lawrence and State of South Dakota, United States of
America, Miner, 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 relates to certain new and useful improvements in pumps, and
it has for its objects among others to provide a simple and cheap double acting
pump by which the water may be elevated from great depths and while it is
designed primarily for use in mines it will of course be understood that the
invention is not restricted to such use. It is composed of pipes connector
together by suitable couplings permitting of ready repairs when necessary and
allowing of the pump being packed in small compass, for storage or shipment.
Other objects and advantages of the invention will hereinafter appear and the
novel features thereof will be specifically defined by the appended claims.
The invention in this instance resides in the peculiar combinations and the
construction, arrangement and adaptation of parts, all as more fully hereinafter
described, shown in the drawings and then particularly pointed out in the claims.
The invention is clearly illustrated in the accompanying drawings, which, with
the letters of reference marked thereon, form a part of this specification, and in
which
Figure 1 is an elevation of the improved pump.
Figure 2 is a central vertical section through the same.
Like letters of reference indicate like parts in the different views.
Referring now to the details of the drawings by letter, A desiguates the
cylinder which may be of any length desired and in which works the plunger or
piston B working tightly therein and carried by the rod C that works through a
stuffing box D on the top of the cylinder as shown. The stuffing box is mounted
on the cross shaped union E to the nipple upon the under side of which the
cylinder is connected. To the lateral nipples of this union are connected the
branches F and F in each of which is a flap valve while to the end of
the branch F is connected the elbow G to which is connected the vertical pipe H
to the lower end of which is joined the elbow H' which connects by the lateral
branch I with the coupling to which is connected the pipe that extends into the
water and represented by the letter. In this lateral branch 1 is a flap valve I'
while J is another flap valve in the pipe K connecting the coupling; with the
coupling K to which the lower end of the cylinder is connected as shown. This
coupling K has a lateral socket k to which is connected the lateral pipe Lin
which is a flap valve land to the outer end thereof is joined the elbow M in which
is secured the lower end of the vertical pipe N the upper end of which is held in
the coupling O on the outer end of the lateral branch pipe F and to which the
discharge pipe is designed to be secured and which may lead to any desired point
of discharge.
The operation will be readily understood from the foregoing description when
taken in connection with the annexed drawings, and a further detailed description
thereof is uot deemed necessary. The stuffing box is provided with a cap through
which the rod C works.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
1. The combination with the cylinder and the plunger and its rod working
therein, of the lateral branches from opposite ends of the cylinder and the vertical
pipes and connections with said branches and the valves in said branches,
substantially as shown and described.
2. The combination with the cylinder and its stuffing box, of the plunger, its
rod working through the stuffing box, the lateral branches from the cylinder, the
vertical pipes connected with said branches, the valves in said branches, and the
valve between the lower end of the cylinder and the inlet pipe, substantially as
described.
3. The combination of the cylinder, its stuffing box, the lateral branches at the
upper end of the oylinder, the valves in said branches, the plunger, its rod, the
vertical pipes and their connections with the lateral branches and with the couplings
at the lower end of the cylinder, and the valves in said connections, all substantially
as shown and described.
