Improvements in Hydraulic Rams,
We, WILLIAM EVANS, of The Westlands Compton Road, Wolverhampton, of
the Firm of Joseph Evans & Sons, Hydraulic Engineers, of Heath Town, Wolver-
hampton, and ABRAHAM HOPwood, of 3, Culwell Terrace, Cannock Road,
Wolverhampton, Engineer, all in the County of Staffordshire, do hereby declare
the nature of this invention to be as follows:-
This invention is for improvements in hydraulic rams for raising water, and
relates to that part of a ram commonly known as the beat or waste valve.
Various kinds of valves have been used for this purpose, but it has been found
that satisfactory results cannot be obtained with these valves over a certain size;
hence the necessity for using a number of valves in the larger size rams.
Instead of the circular disc, with a single seating or face round the outer edge,
we use an annular ring, with faces on both the outer & inner edges of the same;
corresponding faces being provided on the valve seat, having an annular space
between them, through which the water escapes when the valve is open; the
inner & outer faces of the valve seat being connected together (preferably in one
casting) by bars or wings crossing the annular space aforesaid. The valve itself
is also provided with bars or wings, which connect the annular ring with a suit-
able socket or guide to keep it in position. An arrangement is also provided
for adjusting the lift or stroke of the valve. The valve or valve seat may have
facings of leather, india-rubber, vulcanite, or other suitable material for making
it tight when the valve is closed. It will be seen from the above description that
the capacity of this valve is much greater than of one constructed in the ordinary
way, as the water can not only escape through the space between the outer face of
the valve & its seat, but also through the circular orifice in the centre of the
valve & the space between the inner face of the valve & its seat.

page_text: 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:-
This invention is for improvements in hydraulic rams for raising water, and
relates to that part of a ram commonly known as the beat or waste valve.
Instead of the circular disc with a single seating or face round the outer edge,
we use an annular ring with faces on both the outer and inner edges of the
same; corresponding faces being provided on the valve seat, having an annular
space between them through which the water escapes when the valve is open.
The inner and outer faces of the valve seat are connected together (preferably
in one casting) by bars or wings crossing the annular space aforesaid.
The valve itself is also provided with bars or wings which connect the annular
ring with a suitable socket or guide which slides on the adjustable stud provided
for that purpose.
The beat or waste valve herein described is illustrated by Figs. 1, 2, 3, & 4, on
the drawing herewith; Fig. 1 being a sectional elevation through the centre of
the valve and its seat; Fig. 2 an elevation of the same; Fig. 3 is a plan of the
valve and Fig. 4 is a plan of the valve seat.

A is the valve seat.
"B" is the valve.
"C" is the adjustable spindle on which the valve "B" works.
"D" is the lock nut for locking the spindle "C" in the position to give
greater or less lift to the valve "B," as may be required.

"a², a¹ are the inner faces of the valve seat.
"b, b

are the outer faces of the valve.

, are the inner faces of the valve.
It will be seen that the capacity of this valve is much greater than of one
constructed in the ordinary way, as the water can not only escape between the
outer faces of the valve & seat "a" & "b"; but also between the inner faces "a"
& "1"
Having now particularly described the nature of our said invention; we
declare that what we claim is:
(1.) An hydraulic ram beat or waste valve substantially as illustrated and
described.
(2.) The application of a valve as herein illustrated and described for the
purpose set forth.
