I, THOMAS CASSWELL MOLESWORTH, of Ketton, near Stamford, in the County of
Lincolnshire, Brewer, and Spirit Merchant, do hereby declare the nature of this invon-
tion to be as follows:-
The object of my invention is the construction and employment of hydraulic rams
that will be found very suitable for low falls.
My improvements relate to, and consist in, the application to the rain hox, of a
beat valve swung on a pendulum, the motion of which is regulated by a weighted
lever.
A convenient way of applying the invention is by suspending the beat valve from
a vertical shaft free to oscillate from a bearing projecting from the body of the
machine and counterbalanced by a weighted lever. The ram box when fitted in the
manner before described may be sot horizontally instead of vertically, whereby the
drive water is not turned at right angles as heretofore usual, but has a direct course
and flows out at the lowest part of the box; and the invention is particularly adapted
for low falls. Instead of a pendulum, a spring may be used, or the two combined, and
all the moving parts are arranged on the exterior of the ram, except the beat valve,
and the clack valve.

page_text: L, THOMAS CASSWELL MOLESWORTH of Ketion, near Stamford, in the County of
Lincolnshire, Brewer and Spirit Merchant do horoby 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 :-
The object of my invention is to improve the construction and employment of
hydraulic rams and to so arrange same that they will be especially suitable for low
fulls.
My improvements relate to and consist in the application to the ram box of a
boat valve swung on a pendulum, the motion of which is regulated by a weighted
lover or spring.
My invention will be best understood by reference to the accompanying drawings
which show so much of a hydraulic ram constructed according to my invention as will
be necessary to explain same, Figure 1 boing a side elevation, and figure 2 shews the
pandulum valve when swung by a spring from a bracket instead of being counter-
balanced as in the other arrangement.
A convenient way of applying the invention is by susponding the boat valve A from
a vertical shaft or pendulum B free to oscillate in a bearing carried by a bracket
projecting from and secured to the air chamber of the machine, the said pendulum B
being counterbalanced by a weighted arm or levar D. The ram box E when fitted in
the manner before described may be set horizontally as shown instead of vertically
whoroby the drive water which ontors by the conduit F is not turned at right angles
as heretofore usual but as a direct course and the escape water flows out by tho
valve A at the lowest part of the box; and the invention is thus particularly adapted
for low falls. Instead of a counterbalanced pendulum, a spring B as shewn at
Figure 2 may he used or the two combined and all the moving parts are thus
arranged on the exterior of the rant, except the beat valve and the clack valve.
As before stated the drive water enters down the conduit F and will then close
the valve A this stoppage of the flow of the drivo water will then cause the
opening of the clack valve situated between the ram box E and the air chambors (¹
and a quantity of water will then be forced into the air chamber and out by a
delivery pipe & to a higher level until the clack valve closes when the balance D or
clusticity of the pendulum will again overcome the prossuro of the drive water and
enuse the valve A to again open and this action will continuo automatically.

page_text: 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 :-
In hydraulic rams the beat valve A suspender from vertical shaft or pendulum B
the motion of which is regulated by lever D weighted as shewn or by spring or their
equivalents all substantially as and for the purposes described and illustrated with
reference to the accompanying drawings.
