" IN LIFT PUMPS
Year: 1885

page_text: 1, ALFRED JULIUS BOULT, of 323 High Holborn in the County of Middlesex;
Engineer, do hereby declare the nature of the said invention for IMPROVEMENTS
"
IN LIFT PUMPS" a communication from Antonio Ferrero, of Genoa, Italy, Gentleman
to be as follows:-
This improved pump consists in a cylindrical vessel within which works a
circular piece that has a coueshaped internal aperture this piece is closely fitted to
the cylinder. Above the said moving piece carries a guide for the stem of a valve
formed like a grating (viz perforated) a metal disc bears upon this grating and
guided by two rods, this disc serves as a valve.
On the upper part of this valve gear a stirrup piece is fixed and serves to connect
the valve gear with a vertical rod. Another hollow piece, similar to the one
moving in the cylinder is fixed at the top of the latter and is also surmounted by
a stirrup piece which has a hole at the centre and serves as a stop. The said
cylinder is surmounted by a domeshaped cover from which rises the pipe conveying
the water to the spout.
The rod is fixed on the movable hollow casting after the grate shaped valve and
the disc above it have been threaded on the rod. The parts of the rod are
connected by screw-couplings so as to make its length adjustable.
Above the rod passes through a pump body and its end is connected with a beam
fulcrumed on th pump-framing; the other end of the beam has depending from it
a rod attached to a suitably fulcrummed lever and operated by any suitable means,

page_text: I ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex
Engineer do hereby declare the nature of this invention (a communication from
Antonio Ferrero of Genoa Italy) and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
"This invention will be better understood by reference to the accompanying
drawings.
Fig. 1 is a vertical section of a well with the pump which consists of a metallic
pump barrel c in the interior of which is the lifter proper which consists of a
bucket A which is conical inside and reciprocates in c in which it fits watertight.
On the top of A is a guide D fixed as in fig: 2 in whose central hole slides the
pin of a movable circular grating E see fig 3º. On this grating rests a metallic
disc f guided by two pins g and g³.
*
This disc may preferably be of copper or brass and of the thickness of a
millimetri and for the pressure of the water above acts like a closing valve.
To the apparatus A is fixed a stirrup g into whose centre hole is screwed the
iron pump rod m. n.
In the top of the pump barrel c is a fixed guide with a conical interior and
similarly constructed to A, also surmounted by a fixed guide bracket K, which is
provided with a centre hole through which the pumprod m n passes; i serves as a
guide for this bar m n as also as stop for the valve in its upward movement.
The valve and the guide bracket K are in the dome shaped bottom part r of
the delivery tube which serves to guide the water to the reservoir x.
The pump rod mn must be screwed into the stirrup g after the grating E and
plate fare placed in position.
Before the dome a is fixed to the cylinder c the lower portion of the pump
rod mn must be attached to the upper portion n n which is fixed to the lever r. 8
on the top. This lever has its fulcrum at p and in connection with a link t and
the lever x y which is pivoted at x. forms a lever system for the operation of
the pump.
This system can be supported by any suitable frame A¹ A² B1 B2 of wood or
metal.
In figure 2, A A represents a vertical section of the conical interior of the pump
bucket A, g is the spurpiece with the hole into which the pump rod m n is to be
screwed.
Figure 2a is a plan of the pump bucket with the guide D.
In figure 3 E is the movable grating with its guide rod u.
Fig. 3 is a plan of the movable grating E.
In fig. 3b f is the copper or brass disc acting as a valve.
In fig. 3 g¹ and g² are the guides for disc f
This improved pump reduces friction as most of the parts generally found and
used in ordinary pumps are dispensed with.
One man can easily operate this pump or it can be attached and driven in a
suitable manner by an engine. A considerable quantity of water can be elevated

page_text: in this manner to a convenient height and in a continuous stream in proportion to
the force used.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent I declare that what I claim is
A lift pump consisting essentially of a lifting bucket such as A with a conical
interior fitted with a metallic valve ƒ and grating E in combination with a fixed
guide of like form and having a similar valve traversed by the pump rod the
whole encased in a cylindrical pump barrel of a larger diameter than that of
the delivery tube and operated by a system of ordinary levers substantially as
specified.
