Improvements in Force Pumps.
I, ARTHUR EDWIN WHITING, of Ashtabula Harbor, in the County of Ashtabula,
and State of Ohio, United States of America, Gentleman, 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 new and useful improvements in force pumps, and
the primary object of the invention is to provide a pump of this character that
will be especially simple in construction, durable, economical, and efficient in
operation.
To these ends, my invention consists in the combination and the arrangement
of a plurality of co-acting mechanisms that will be hereinafter fully described,
and the points of novelty will be set forth in the claims.
My invention contemplates a provision of a shaft adapted to rotate by the
descent of a weight or plurality of weights, which shaft in its rotation will be
caused to actuate mechanism, whereby the water will be driven or forced from
the well. I am enabled to accomplish the objects of my invention by the simple
means illustrated in the accompanying drawings, in which,
Fig. 1 represents a side elevation of my improved pump showing a well casing
in section.
Fig. 2 is a section taken on line of Fig. 1, showing a plan view of the
winding drum and operating wheels.
Fig. 3 is a top plan view of the plate covering the well.
Fig. 4 is a detail side elevation of one of the cylinders and the air and dis-
charge chambers.
Fig. 5 is a front elevation of the pump, the well casing being shown in section.

Figs. 10 and 11 illustrate sectional views of plungers or piston heads, which I
employ in carrying out my invention.
Fig. 12 is a reduced top plan view illustrating two force pumps having con-
nections with different water supplies, said pumps heing operated by a single
shaft.
Fig. 13 is a vertical section of the air chamber.
Referring to the drawings, the numeral 1, indicates the well casing covered,
in the present instance, by a plate 2 upon which is supported a plate 21, said
plate 2 having secured at each side thereof hinged traps 3 having semi-circular
recesses 4 cut in their edges to form circular perforations 5 when the traps are
closed.

page_text: The numeral 6 indicates a frame work or derrick composed in the present
instance, of vertical bars 7, oblique bars 8, cross bars 9 and legs 10. Journaled
in suitable bearings on the upper sides of the horizontal bars 9 is a shaft 11
having keyed thercon a drum 12, having a rope or cable 13 wound thereon and
passing through pulley blocks 14 secured to the under side of a transverse bar 15
at the top of the derrick.
Secured to the lower pulley is a transverse bar 16 provided on its under side
with hooks 17 for the reception of the eyes on the upper sides of the weights 18.
The shaft 11 is provided on the outside of the horizontal bars 9 with a cog
wheel 19, which, for convenience of description, I will hereinafter refer to as the
driving wheel.
Journaled in suitable bearings on either side of the driving wheel are cog
wheels 20 having their teeth in mesh with the cog wheel 19. Pivotally secured
to the sides of the cog wheels 20 near the peripheries thereof are two pitman
rods 21 extending downwardly and having their lower ends pivotally connected
as indicated by the numeral 22 with the upper ends of the piston rods 23.extend-
ing through the circular openings 5 in the hinged traps 3. The lower ends of
said rods are provided with piston leads or plungers which are adapted to work
alternately in cylinders 24, suitably supported by vertical arms 25 which pass
through openings 26 in the plate 2¹.
Secured to the bottoms of the cylinders 24 are pipes 27 and 28 having a
three-way connection 29 secured to their lower ends and said connection has
secured thereto a pipe 30-extending into the water-and-provided at its lower end
with a nozzle or strainer of any approved construction. The said pipes 27
and 28 are connected near their upper ends with short laterally extending.
pipes 30 leading to the discharge chamber 31 which communicates with an air:
chamber_32_as is usual in force pumps. Said pipes 27 and 28 are provided with
valves adapted to be operated in the usual manner to permit the water to be-
drawn from the well into the cylinders 24 as the pistons reciprocate therein and
prevent the same from being forced back into the well upon the downward stroke.
of the piston. The pipes 30 have valves therein permitting the entrance of the
water to the discharge chamber and preventing its escape as usual.
Secured to the discharge chamber at or about the center thereof is a pipe 32¹
having pipe connections 33 leading to any point where it is desired to run the
water. The rods 25 are braced by means of plates 34 provided with slots 35
for the passage of said rods. As a means for securing the plates 34 in a fixed
position upon the rods I provide set screws 36, and braces 34.
At each end of the plates 34 I provide a semi-circular recess 37 and the verti-
cally disposed tube 40 having a longitudinal slot 40¹ adapted to receive the pin 41
formed upon
the locking bolt or rod 42 and thus hold said rod in place. The
plate 34 also has a pair of ears 38 between which is pivoted the locking
member 39, the free end of which is provided with an aperture 50¹ adapted to
register with the opening in the vertical tube 40, when the locking member 39
is properly adjusted, and thereby enabling the piston or pump rod to be locked
within the semi-circular opening 37, or easily removed therefrom by withdrawing
the bolt 42 and permitting the member 39 to be swung outward. The bolt 42
may be easily withdrawn as far as its pin 41 will permit, by means of
the wire 43 extending upward to the top of the well and provided with handles 44.
By reference to Figure 9 it will be seen that a single cylinder is used and the
discharge chamber is dispensed with and in lieu thereof a pipe 45 is provided
having communication with the pipe 46 through which the water leaves the
well. It will be further noted that as there is only one piston rod and pitman
to be operated, there will be no necessity for more than one of the wheels 20.
Attention being called to Figure 6, it will be noted that I provide two drums 12
having the ropes 13 extending over the pulley blocks 14, which, in the present
instance, are shown secured to the transverse beams of the ceiling.
The numeral 46' indicates cylinders having pistons therein and valve controlled

page_text: connections 47 leading to the well. I preferably provide in this form of pump
four working cylinders oppositely disposed, which, it will be obvious, will neces
sitate the duplication of the gear wheels 19 and wheels 20 at the opposite ends
of the drums. For causing a continuous flow of water from the outlet pipe 48,
I provide air chambers 49 having valve controlled connections with the pipes 47
leading to the cylinders.
Secured to the shaft 11 is a crank 50 by which means said shaft and the drum
secured thereto are rotated when it is desired to lift the weights to the top of the
derrick, and, in order to enable this to be done without operating the pump I
mount the wheels 19 loosely upon the shaft and provide the shaft with ratchets 51
whose teeth are adapted to be engaged by the pawl 52 on said wheels, and it will
be seen that by reason of this construction, the drum can be rotated in the direc-
tion to wind or lift the weights without operating the pump mechanism.
Referring to Figure 10, the numeral 53 indicates two semi-spherical sections of
rubber centrally perforated for the passage of the piston rods 23, which, in the present
instance, will be provided above the top section and below the bottom section
with nuts 54 adapted to be tightened to force said sections together and as said
sections are formed of yielding material it will be obvious that by forcing them
together they will be caused to expand, thus compensating for wear.
In the form illustrated in Figure 11, the numeral 55 indicates two discs cen-
trally perforated for the passage of the piston rod and having leather discs 56
interposed between them. The piston rod is provided above the disc 55 and
below the lower disc with locking nuts adapted to be turned to bring the discs
in close contact with the leather discs which leather discs, it will be apparent,
may be readily removed and replaced when worn out.
My invention is ready to operate when the weights 18 have been elevated by
a proper rotation of the winding drums 12 which will cause said drums to re-
versely rotate thereby inducing the rotation of the gears 20 by means of the gear 19,
thereby establishing a reciprocation of the pistons 23 causing the water to be
drawn into the cylinders alternately and forced therefrom through the discharge
chamber and pipes to the point where it is desired to use the same.
Referring to Figure 12 it will be noted that two drums 12 are placed upon a
single shaft having operative connection with the pumps, which, in the present
instance, are adapted to lead to different sources of water supply.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
1. In a pump, a brace plate having a vertical slotted tube and recesses, a
device closing and unclosing said recesses, a bolt working in said tube and having
a pin working in said slot, all arranged as set forth.
2. In pumps, a brace plate having a recess to receive a pump rod, said plate
carrying a pivoted member for opening and closing said recess, a vertical tube on
said plate and a bolt working in said tube to lock and unlock said movable
member, all arranged as set forth.
3. In a pump, a brace plate having slots for the rods supporting the pump,
also having semi-circular recesses for the plunger rods, perforated pivoted
members carried by said plate to retain the plunger rods in place and tubes
having plungers working therein and registering with the perforations in said
members, thereby locking the plunger rods in position, all arranged as set forth.
4. In a pump, a perforated brace plate having a semi-circular recess, a pivoted
member having a perforation carried by said plate, a slotted tube attached to
said plate and having a bolt with a pin working in said slot and registering with
said perforation, all arranged as set forth.
5. The herein described force pump consisting of a pair of cylinders, a dis-
charge chamber, pipes and suitable valves connecting said cylinders and dis-

page_text: charge chamber, a supply pipe and valves therefor extending and uniting below
said cylinders, pistons fitting said cylinders and having pump rods attached
thereto extending to the top of the well, and suitable driving mechanism for
reciprocating said rods, in combination with a pivoted locking member adapted
to encircle said rods and hold the same in their operative positions, and having
a stop pin to lock said members in engagement with said rods, and suitable
means to control said rods from a. position at the top of the well, substantially
as described and for the purpose set forth.
