Improvements in Water Elevating or Pumping Apparatus.
I ELMAR AUGUSTUS MESSINGER, Merchant, of Box 2399, Boston, Massa-
chusetts, U.S.A. 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 water elevating or pumping apparatus,
and its novelty will be fully understood from the following description and claim
when taken in conjunction with the annexed drawings, in which-
Figure 1 is a vertical section of my improved apparatus.
Fig. 2 is an enlarged detail section of a portion of the pump.
Referring by letter to the drawings, B indicates the pump, and C the motor for
actuating the pump.
As shown in Fig. 1 of the drawings, the casing D of the pump B is of a special
construction, being formed in two parts, and it comprises the base or main section E,
in which is formed the receiving-chamber e, the piston-cylinders f, the ports g,
connecting the receiving-chamber e and the cylinders f, and the passages leading
from the piston-cylinders above the ports g and the section F, in which is formed
the air or discharge chamber i. This section F is mounted upon the section E
between the cylinders fand is secured in any approved manner, and it is provided,
as shown, with a nozzle j, whereby a ready connection of the discharge-pipe may
be effected.
1, indicate the upwardly-opening valves of the pump, which control the ports g
and passages h, respectively, and m m' indicate the pistons which are arranged in
the cylinders f, as shown. These pistons m m' are connected to rods n, and these
rods are connected in turn to the ends of a rocking-beam p, whereby it will be seen
that when said beam is actuated the pistons will be reciprocated in their respective
cylinders.
In the practical operation of the pump it will be seen that when one piston-the
piston m', for instance-moves upwardly, so as to draw water from the receiving-
chamber e into its cylinder, the other piston m, will move downwardly and seating
the valve and opening the valve k will force all of the water which it had drawn
into its cylinder by its preceding upward stroke into the air or receiving chamber i
and out through the discharge-pipe. Thus, when the pump is in operation, the
water is forced in a steady and continuous stream, which is a desideratum.
G indicates the main frame of the motor of my improved apparatus. This main
frame comprises, by preference, the upright bars q and the transverse bolts r
connecting the same, and it affords bearings for the several shafts H, I, J, K, and L
comprised in the motor. The shaft H is provided with a crank s, which is connected
by a pitman t to a crank-branch u of the rocking beam p, and motion is transmitted
from the drive-shaft K to said shaft H through the medium of the gear-wheel M
on the shaft K, the pinion N and gear-wheel P on the shaft J, the pinion Q and
gear-wheel R on the shaft I, and the pinion S on the shaft H. The gear-wheel M
is loosely mounted on its shaft K, but it is provided with a spring-pressed pawl T,
adapted to engage the ratchet-wheel U, which is fixed on the shaft. By this
construction it will be seen that when the shaft K is rotated in the direction of
the arrow the wheel M will also be rotated and motion will be transmitted to
the pump through the medium of the train of gearing described.

page_text: Mounted on the shaft K, but within the frame, is the gear-wheel Y. This gear-
wheel meshes, as shown, with the pinion Z on the shaft L, and this shaft is
provided, as shown, with a crank M', actuated by manual or other power whereby
said pinion Z may be readily rotated in the direction indicated by the arrow
thereby driving the pump through the intermediation of the whole of the
gearing.
In order to prevent freezing of water in the pump and consequent damage
thereto, I provide the mechanism a part of which is better illustrated in Fig. 2,
through the medium of which any water that remains in the piston-cylinders f, after
the pump has stopped, may be permitted to pass back into the well or other source
of supply. This mechanism comprises the levers a², which are fulcrumed upon
.hangers depending from the pump-casing, rods 6' connected to the outer ends of
the said levers and extending through stuffing-boxes c2 and adapted to engage the
valves, a bar d' arranged between the conduits h and above the receiving-
chamber e, rods e connecting said bar d2 and the inner ends of the levers a³, and a
spring interposed between the upper wall of the chamber e and the bar d2 and
adapted to normally hold said bar and the parts connected therewith in the positions
illustrated in Fig. 2. By reason of the construction described it will be seen that
when the pump is not in operation, and it is desired to drain the water from the
piston-cylinders f, it is simply necessary for the attendant to press downwardly
upon the bar d, when the valves will be raised and any water in the said
cylinders will be permitted to pass into and through the receiving-chamber e and
back into the well or other source of supply.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. The pump described comprising the base or main section E, having the
receiving-chamber e, the piston-cylinders f, the ports g, connecting the receiving-
chamber e, and the cylinders f, and the passages leading from the piston-cylinders
above the ports g, the section F, in which the discharge-chamber is formed, the
upwardly opening valves j¹ controlling the ports g, the upwardly opening valves k,
controlling communication between the passages h, and the discharge-chamber,
pistons arranged in the cylinder f, the bar d², arranged above the receiving-
chamber e, and between the passages h, the levers a², fulcrumed below the receiving-
chamber e, rods connecting the inner ends of said levers and the bar d³, rods
connected to the outer ends of the levers a², and extending through the receiving-
chamber e, and engaging the valves, and a spring interposed between the upper
wall of the receiving-chamber e, and the rod d, and adapted to normally hold the
said bar and the rods connected therewith in such a position that they will not
interfere with the operation of the valves when the pump is in use, substantially as
specified.
