page_text: I, WILLIAM H. CLOUD of Detroit in the County of Wayne and State of
Michigan one of the United States of America 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 that class of pumps known as "deep well" pumps, in
which the cylinder of the pump is suspended within the well and below the
freezing point. The cylinder in the act of pumping is raised and lowered by
means of the ordinary pump handle. The piston head is fixed stationary, over
which the cylinder travels in its up and down movements, causing in its down-
ward movement a vacuum in the cylinder, whereby the water is lifted from the
well into the cylinder, the water being discharged from the cylinder and the
pump by the upward movement of the cylinder, as hereinafter fully set forth. In
the construction of this pump but one watertight joint is required, that being in
the lower head of the cylinder C; and my invention consists in the arrangement
of parts, as hereinafter set forth, and pointed out particularly in the claims.
In the drawings forming a part of this specification, Figure 1 is a perspective, in
elevation, of my invention. Figure 2 is an enlarged' longitudinal section of same
on dotted line x x of Fig. 4. Fig. 3 is a top view of upper cylinder-head and its
dome. Fig. 4 is an enlarged view of the valves. Fig. 5 is an enlarged isometrical
perspective of the piston and its guide pin. Fig. 6 is an isometrical perspective of
the piston, having the packing or leather covering removed from the concave of its
periphery. Fig. 7 is a view of the leather covering partly broken away."
In the drawings, E represents the inner stationary cylinder. At the centre of
its longitudinal length I locate a series of port-holes, P, and over said port-holes
I locate the upper valve, G, being secured within the cylinder E by means of a set-
screw, e. Said valve has a discharge-opening, i, through the centre, over which
I locate the common leather cap v. On said leather cap I locate a metal weight, a³,
upon which the free end of the spring 82 presses, as clearly shown in Figs. 2 and 4.
is a packing surrounding the body of the valve. Said valve is made large enough
to fill snugly the hollow of the cylinder E, as clearly shown in Fig. 2. I locate
another valve, G, being a duplicate of the one described in said cylinder near
its lower end as clearly shown in Fig. 2. I attach to each end of said cylinder a

page_text: coupling or reducer, R, one being screw-threaded to said cylinder and screw-
threaded to receive a suction-pipe, S, leading to the water, the other screw
threaded to receive a discharge pipe, d, as shown in Figs. 1 and 2. Said pipes are
of a less diameter than the cylinder E. I attach surrounding said stationary
cylinder a piston, B. Through the hub h² of said piston I form a hole, N.
Through said hole the cylinder E is inserted, and by a set screw, 83, through the
hub said piston is firmly secured to the cylinder at its longitudinal centre.
The periphery of the piston I form concave as shown at t² of Fig. 6. Projecting
horizontally from the centre of the concave is a series of pins or studs, z, as shown
in Figs. 2, 5, and 6. I cover the periphery of the piston with a packing, such as
leather.
In Fig. 7 I show a strip of leather. This I cut wider than the face of the
periphery of the piston and long enough to pass around the piston. I punch
through the leather a series of holes a³, which are so located in the leather
that said holes will register with and pass freely over the series of studs z of the
piston as clearly shown in the Figs. 2 and 5. I then confine the covering L to the
piston by winding a wire 'w over the covering above and below the series of studsz,
as shown in Figs. 2 and 5. These studs project through the covering or packing
far enough to separate the wires w and prevent them from coming together and to
form two bearings around the leather. This piston I locate in the traveling
cylinder C as clearly shown in Fig. 2. Said cylinder is provided with a traveling
head H2, at the lower end. Said head has a neck, which fits snugly over the
stationary cylinder E. The neck of said head is chambered, within which I locate
a packing t¹ (see Fig. 2). d¹ represents a packing around the lower end of the
cylinder C where it joins the lower head.

I attach to the upper end of the cylinder a travelling head, F, its central portion
forming a dome, D. Through' said dome is a hole, H, to receive freely the
stationary cylinder E, as shown in Figs. 2 and 3. Surrounding the hole H, in
the dome is a series of, vent holes, a, for the admission and discharge of air to the
cylinder C. as
as it is raised' and lowered, as will be hereinafter fully explained.

Passing through the holes 9 of the heads F and H of the travelling cylinder are
rods r, which are provided with nuts o¹ at each end by which the heads are firmly
bound to the cylinder. I anchor firmly in the upper face of the piston B a guide
rod, s, being screw-threaded to the piston, as shown at g of Fig. 2. Said rod is
longer than the distance travelled' by the cylinder C. Its upper free end projects
freely through the hole as in the dome of the cylinder C, as shown in Figs. 1. 2.
and 3. The object of this rod is to prevent the cylinder C from turning on the
cylinder Ę as it is moved up and down. Projecting from the cap F is a lug, o, to
which I pivot at a the operating rod t of the pump. The other end of said rod
extends upward through the well-top, and is attached to one end of the pump-
handle h, as shown ate of Fig. 1. The discharge-pipe d extends upward through
the well-top 'n and chair C¹. To its upper end I attach the coupling T, and by the
chain and coupling the pump is suspended in the well. I attach to the upper end
of the coupling an extension pipe, m, which is provided at the top with a cap, J, in
which I'fulcrum the handle h. Said pipe acts also as an air-chamber. I attach to
the pipe m, and the well-top a brace-rod, f, and to the horizontal opening of the
coupling T, I attach the spout 8 of the pump.
I
The operations are as follows: When the pump handle h, is raised from the
dotted position of Fig. 1. to its normal position, the cylinder C moves down from
the dotted position of Fig. 1. to its normal position, and when the handle is thrown
down to the dotted position of Fig. 1' the cylinder C rises' to the dotted position of
Fig. 1 and the position shown in Fig. 2. It will be observed as the cylinder C is
moved down from the position of Fig. 2 a vacuum is formed in said cylinder below
the stationary piston B, thus producing a suction in "the lower half of the
stationary cylinder E, causing the lower valve G, to rise and the water to flow
through the series of port-holes into the descending cylinder C, and as said cylinder
ascends the lower valve closes, when the water in the cylinder C. below the piston

page_text: is forced back through the ports P and up through the upper valve, G, said valve
opening as shown in Fig. 4, when the water will be forced out through the spout of
the pump. As the cylinder C, rises and falls the air passes in and out at at the
holes a of the dome.
Having now particularly described and ascertained the nature of my said
Invention and in what. manner the same is to be performed, I declare that what
I claim is;
1. In a pump, the combination of the stationary cylinder, having port-holes, P
and valves G located therein, the discharge and suction pipes coupled to said
cylinder, the piston made fast to the cylinder, the guide-rod anchored to the piston
and passing through the dome, the travelling cylinder, its lower head being air-
tight, its upper head or dome having a series of air-holes, and mechanism for
reciprocating the travelling cylinder, as, and for the purposes specified.
2. In a pump, the combination of the stationary cylinder, having port-holes mid-
way of its length, the valves located in said cylinder, the suction and discharge
pipes joining said cylinder, the said cylinder, the guide-rod anchored to the piston,

lower head having a packing around the stationary cylinder, the upper head having
a dome in which is a series of air-holes, the guide rod of the piston working
through the upper head, the bolts for securing the heads to the travelling cylinder,
and means for operating said travelling cylinder, substantially as specified.
3. In a pump, the combination of the stationary cylinder, its port-holes and
valves, the piston anchored to said cylinder, the guide-rod anchored to the piston,
