I WILLIAM HUCKS, of No. 12, Oval Road Upper James Street Camden Town, in
the County of Middlesex Engineer do hereby declare the nature of this invention to
be as follows :-
My invention relates to a ring and blade, and the actuating of the same by an
eccentric disc, to produce the suction and propulsion, inside a rotary pump.
My improvements are applicable to rotary pumps requiring to be worked at a slow
speed and capable without the aid of valves of producing a vacuum in the suction
pipe and an unlimited power of forcing liquids in the delivery pipe or rising main.
In carrying out my said invention into practice I make a plain cylinder of any
suitable material, with an inlet and outlet port. The rotary motion inside the said
cylinder is a plain eccentric keyed on a shaft. the said eccentric fitted into a ring or
strap having a tongue or blade fixed or cast on its outside circumference, when this
ring or strap is actuated by the eccentric the tongue or blade acts as a guide and imparts
a reciprocating motion to the eccentric strap or ring, this tongue or blade forms a
stop, cutting off any communication between suction and delivery except through body
of pump cylinder as required.
WILLIAM HUCKS.

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 a ring or rings and blades and the actuating of the same
by an eccentric disc so as to produce the suction and propulsion inside a rotary
pump.
My improvements are applicable to rotary pumps requiring to be worked at a slow
speed and capable without the aid of valves of producing a vacuum in the suction
pipe and an unlimited power of forcing liquids in the delivery pipe or rising main,
and further of allowing solid and other matter to pass through the body of the pump
during the process of pumping without destroying its efficiency.
In the drawings Fig. 1 is a central vertical section of a pump constructed according
to this invention. Fig. 2 is a central transverse section of the pump at line, a b, Fig. 1.
The arrows indicate the course of the propelled liquid.
In carrying my said invention into practice I make a plain cylinder Figs. 1 and 2
of any suitable material with an outlet and inlet A, and B. The rotary motion inside
the said cylinder consists of an eccentric disc C, notched in such manner as to form
the blades D, Dm, which dise C, is keyed eccentrically on a shaft E, passing through
glands F, in order to impart to the said disc C, a rotary motion. Power is applied to
shaft E, in any convenient manner.
Rings or straps G, are fitted on the sides of the disc C, to which rings or straps a
blade H, is bolted or cast on in such a manner as to saddle the disc (, and its
blades D, Dm, and, that when the rings or straps G, are actuated by the eccentric
dise C, it imparts an eccentric motion to the ring or strap G, and a rising and falling
motion to the blade H, causing the blade to slide on the face of the moving centre J,
the same being held thereto by the pressure of the out flow liquid. The blade H,
is so constructed at points K, K, at its junction with rings G, as to form a shield
or saddle for the notched portions of the eccentric disc to pass through and in such
manner as to always leave one blade D, or the blade D, in the shield or saddle before
the previous one has left, thus obviating liquid passing from the outlet A, to the inlet
port B.
Further the blade H, is so shaped at the point L, that during the reciprocating
motion it fulfils the function by closing against seating O, and prevents the liquid
returning during the interval when the propelling blade Dm, of disc C, in its revolution
is passing out of action from outlet A, to inlet port B.
The blades D, Dm, on the disc C, in their passage through the shield K, K, which
is actuated by the eccentric straps G, are capable of acting like a cutting instrument
to break or remove any hard or soft substance that may have entered the pump and

page_text: the motion of the blade D, will eventually eject such matter into and from the
outlet port. D, also acts as a cutter at its point of contact with the inner periphery
of the cylinder.
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. The blade or slide H; the straps G, fitted to the revolving disc C, and
blades D, Dm, which revolve inside the cylinder N, constructed and operating as
herein set forth.
2. The mode in which the blade or slide H, separates the inlet portion of the
cylinder from the outlet portion and the manner in which the pressure of liquid in
outlet pipe is utilized in order to keep the blade or slide H water tight against the
moving guide J as set forth.
3. The mode of producing a valvular action at the points L and O.
4. The cutting or breaking action of the blades D, Dm, at the points K, K, and
within the cylinder thereby removing any obstruction that may be passing through the
pump when in action.
