JAMES L. FAGAN, OF ANAQUA, TEXAS.
PUMVIP.Specification of Letters Patent No. 23,019, dated February 22, 1859.
To all whom it may concern:
Be it known that I, JAMES L. FAGAN, of
Anaqua, in the county of Victoria and State
of Texas, have invented a new and Improved
a Pump; and I do hereby declare that the fol-
lowing is a full, clear, and exact description
of the same, reference being had to the an-
nexed drawings, making a part of this speci-
fication, in which-
10 Figure 1, is a vertical central section of
the principal working parts of my inven-
tion. Fig. 2, is a horizontal section of do.,
taken in the line x, x, Fig. 1. Fig. 3, is a
horizontal section of do. taken in the line
15 y, y, Fig. 1.
Similar letters of reference indicate cor-
responding parts in the several figures.
This invention consists in having a hollow
cylinder attached to a tubular shaft and
20 giving the same a reciprocating partially ro-
tating movement, the cylinder being pro-
vided with valves and a vertical radial
flanch or piston and in connection with a
vertical stationary stop which is fitted with-
25 in the cylinder, the whole being arranged as
hereinafter fully shown and described,
whereby a simple, efficient, and durable
pump is obtained.
To enable those skilled in the art to fully
30 understand and construct my invention I
will proceed to describe it.
A, represents a hollow cylinder which is
attached to the lower end of a tubular shaft
B, the lower end of cylinder A, being fitted
35 water tight in a circular step C, attached to
a bed piece D, which is placed at the bottom
of a reservoir or well from which water is
to be elevated. The shaft B, has its bearing
in a cross piece a, of a framing arranged
40 in any proper way, and the upper end of
said shaft is fitted in a hollow stationary
cap E, which is provided with a nozzle or
spout F.
The cylinder A, is made to communicate
45 with the shaft B, by means of two curved
tubes c, d, each one of which has a valve e,
at its upper end opening outward into shaft
B, see Fig. 1. Within the cylinder A, a
flanch or piston G, is secured. This piston
50 is a radial plate attached permanently to the
inner side of the cylinder and extending
inward to a vertical shaft H, which is at-
tached to the bed piece D, and extends up-
ward centrally within the cylinder and is
55 fitted loosely in the top of the cylinder. To
the shaft I-I, a radial plate I, is attached, saidplate extending to the inner side of the cyl-
inder A, see Fig. 2.
The plate I, and piston G, divide the cyl-
inder A, into two compartments f g, and 60o
each compartment has an aperture h, made
in it, said apertures being each provided with
q valve i, opening inward, see Fig. 2.
The tubes c, d, each communicate with a
compartment of the cylinder, the tube e, 65
communicating with the compartment f, and
the tube d, with the compartment g.
On the upper part of the shaft B, there
are placed loosely two bevel wheels h', Ak',
into which a corresponding wheel i', on a 70
horizontal shaft J, gears. To the shaft B,
two pawls K, K, are attached which are
made to catch alternately into their respec-
tive wheels h', h', and also are released alter-
nately therefrom by means of springs j, j, 75
and inclined planes k, k. The springs j,
being attached to the shaft B, and the in-
clined planes to the framing which supports
the working parts,-horizontal pins 1, are
also attached to the framing, the use of 80
which will be presently explained. The
pawls K, bear against the smooth surfaces
of the bevel wheels h',-notches m, being
made in them into which the pawls catch, at
the proper time, see Fig. 3. 85
The operation is as follows: Power is ap-
plied to the shaft J, in any proper manner
and a reciprocating partially rotating move-
ment is given the cylinder A, through the
medium of the gearing h', h', i, and ratchets 90
K, K, the ratchets being made to catch alter-
nately into the notches m, of their respective
wheels by means of the springs j, and ele-
vated therefrom by the inclined planes k, k,
the pins 1, preventing the pawls from drop- V5
ping into the notches during the return
movement of the wheels h', when the notches
pass under the pawls. The piston G, forces
the water alternately from the chambers f g,
through their respective tubes c, d, into the 1oo
shaft B, from whence it is' discharged
through the nozzle F. The valves h, of
course close by the pressure of the water
under the action of the piston G.
By this simple invention a very efficient 105
submerged pump is obtained. There are but
few parts, very simply arranged and in such
a way that they will not be liable to get out
of repair.
I do not claim separately any of the parts 110
herein shown and described, irrespective of
their particular arrangement and adaptation
