EDWARD WILLOUGHBY ANDERSON, of the City of Washington, in the District of
Columbia, and United States of North America, Attorney at Law and Patent
Solicitor. IMPROVEMENTS IN PUMPS." A communication by William Henry
Garlock and Richard Cooke, both of Denison, in the County of Grayson, State of
Texas, and United States of North America.
The object of the Invention is to construct a pump with a series of valves, inducts,
and educts, the valves working in a chamber, the whole arranged in such a manner
as to allow the admission of water at one end of the chamber, and its discharge at
the other end thereof. The Invention consists cbiefly of a pump barrel or cylinder,
having the usual piston or plunger actuated by a rod passing through one of the
heads thereof, and provided with water passages opening into the cylinder at or near
its ends, and extending inward towards each other, in combination with a valve
chest, with which these passages communicate, said chest or chamber carrying the
educt or discharge nozzle leading into an air chamber, when the pump is used as a
force pump. At each side of this educt, within the chamber or chest, are formed
annular valve seats, having preferably beveled shoulders. Between these shoulders
is an endwise movable valve fitting mugly against said beveled shoulders, and
provided at each end with guide rods working in a reduced portion of the chamber

plates at right angles to each other, but any other description of stem may be
employed, provided it is made in open work or skeleton form.
The chamber is open at each end, and inside of said openings are other valve
Beats and valves. These valve seats are also beveled, and the body of the valves is
correspondingly beveled to form tight joints. The valves have also skeleton stoms
projecting through a reduced passage at the end of the chest. The inward motion
of the latter valves is controlled by a rod extending through the reduced passage,
and in practice I form the valve chest in four sections, with a view to facilitate the
trueing of the valve seats.
In the accompanying Drawing, A represents the pump barrel; B, valve chamber;
C and C³, C¹, valves; D, discharge nozzle.

the said Edward Willoughby Anderson in the Great Seal Patent Office on the
30th December 1879.
EDWARD WILLOUGHBY ANDERSON, of the City of Washington, in the District of
Columbia, and United States of North America, Attorney at Law and Patent
Solicitor. "IMPROVEMENTS IN PUMPS." A communication by William Henry
Garlock and Richard Cooke, both of Denison, in the County of Grayson, State of
Texas, and United States of North America.
Figure 1 is a vertical longitudinal section of the pump; Figures 2 and 3 are detail
views of the same.
The object of the Invention is to devise a double acting force and suction pump,
having a series of valves, inducta, and educts, the valves working in a chamber, the
whole arranged and constructed in such a manner as to allow the admission of
water at one end, and its discharge at the other.
In the accompanying Drawings, A is the barrel or cylinder of the pump, having
the usual piston B and piston rod B' extending through a stuffing box a in one of
the heads O; c, c', are passages opening into the cylinder at or near the end of the
barrel A, and extending inward toward each other carried through the said barrel.
These passages coincide respectively with ducts d, d, leading into a chamber D,
rigidly secured in any suitable manner to the barrel A, and having an educt or
nozzle d'³ leading into an air chamber, when this device is used as a force pump. At
each side of this educt, within the chamber and inside of the ducts d, d', are formed
the valve seats e, e¹, the same being annular, preferably beveled shoulders cast or
otherwise formed in the said chamber. Between these shoulders, inside of the
chamber, is an end wise movable valve f, having collars i, i, fitting snugly against
the beveled shoulders aforesaid, and provided at each end with guide stems & working
in a reduced or narrowed portion of said chamber outside of the valve seats e, et.
These guide stems are usually composed of two plates; at right angles to each
other, as shown in Figure 2, but any desired description of them will suffice, pro-
vided it be made in open or skeleton form, and fit neatly in the reduced passage
exterior to the collars or seats e, e¹.
The chamber D is open at each end, and inside of said openings are valve seats
n, working in connection with which are the valves o, o³.
The seats are
beveled as shown in Figure 1, and the body of each valve is correspondingly beveled
to form tight joints with the seats. Each of these valves has a stem s', of skeleton
form, or of crossed-blades, as above described, projecting through a reduced passage
at the ends of the chamber D. The inward movement of the valves is controlled
by means of a rod m extending diametrically through the passage, as shown in
Figure 1.
The chamber D is usually made in four sections S, S³, S, S³, joined together by
screws or flanged joints. This is done with a view to the trueing of the valve seats
and to securing exact coincidence of the ducts d, d', and passages c, c', as well as for
the introduction of the valves. The operation of the pump is as follows:→
The movement of the piston creates a partial vacuum, which causes the valve o
to rise from its seat n, and the valve f to close upon its seat e, opening a passage
between the opposite seat e', the duct d¹, and educt d², and o¹, to close upon its
Beat n. Water is consequently drawn through the passages 1, 1, duct d, and passage
c into the pump. The water on the other side of the piston is forced through
passage c', duct d, passage 2, and nozzle d³, into an air chamber, pipe, or receptaclo,
as the case may be.
It will be obvious that when the piston returns in the barrel the movements of
the valves are reversed, and water is drawn through the other side of chamber D.

page_text: Having now described my Invention, and the manner in which the same may be
carried into practical effect, I wish to have it understood that I do not desire to
limit myself to the exact details, as herein before described, as these may be varied
without departing from the peculiar nature of the Invention, but what I do
claim is,-
A double acting pump, operating and constructed substantially as herein before
described and shown in the accompanying Sheet of Drawings.
In witness whereof, I, the said Edward Willoughby Anderson, have hereunto
set my hand and seal, this Twenty fourth day of December, in the year of
our Lord One thousand eight hundred and seventy nine.
EDWARD WILLOUGHBY ANDERSON. (LS)
