I, WILLIAM JACKSON, of Birmingham, in the County of Warwick, Engineer,
do hereby declare the nature of the said Invention for "A NEW SOUFFLATING
to be as follows (that is to
ACCUMULATING PUMP OR HYDRAULIC ENGINE,'
say):
My improved pump or engine consists of by preference an angular frame,
which may be made of any suitable material, such as wood or cast iron, in
which frame I prefer forming inlet and outlet ways, and so arranged for
receiving suitable valves and connecting tubes for conducting the water to and
from the inlet and outlet ways. The internal form of this frame may be about
one-fourth the width at one end than it is at the other, and in length about
three times the extent of its widest end, more or less, as may be preferred,
according to use or position or local circumstances where such engine may be
required to be put to work. On the outside of the widest end of this frame
lugs are formed for receiving axes hereafter referred to, and at this end I by
preference arrange my outlet way; the other or narrow end is fitted with
carriage and glands for receiving a shaft by which I purpose the engine to
be actuated. On the sides and ends of the frame I provide flanges or other
equivalent means for securing top and bottom covers made of strong fibrous

or other suitable air and water tight material which may be held conveniently
by metallic or other strips together with screw pins or other like suitable
These fabrics cover the top and bottom or both sides of the frame
and are permitted to be loose and full from the broad end to the narrow end
that they may be capable of expansion and compression similar to the action
of a common bellows. 'On the outsides of these elastic covers I apply by
preference metal plates provided on their broad ends with corresponding lugs
for receiving pins or axes to work in or through the corresponding lugs of the
frame before referred to, which lugs and pins form a common hinge joint or
fulcrum, on which these plates work, so that by the flexible material being
attached to them they will in reality be levers, or, as it were, the top and
bottom of the common bellows, which the apparatus so much resembles. The
narrow end of these plates are provided with an extended strap or lug for
receiving connecting rods, by which they are united to two eccentrics or cranks
formed on the shaft before referred to, and by putting this shaft in motion by
any suitable driving gear, and with by preference the aid of a fly wheel, the
two lever plates working on the joint, also before referred to, will be made to
advance and retire from each other at the narrow end just in proportion to the
amount of excentricity given to the excentrics or cranks from the central line
of the shaft. A continuation of this action will be identical to the action of a
common bellows, and as the flexible material is connected to the frame in
such a way as to make it positively air-tight it is evident that as the top and
bottom plates are forced asunder from the axis on which they work to the
throw of the cranks or excentrics so a vacuum will be produced in the interior,
and into which the water will rush through the inlet way before referred to,
when the inlet valve will close, and as the plates are brought together so the
water will be pressed out and driven through the outlet way, the valve of which
will immediately close as soon as the excentrics have passed the centre, when
the inlet valve will again rise for the water to flow in to fill up the vacuum
now being produced by the rising of the excentrics, and so on as the operation
is continued, the shaft being kept revolving by a handle, pulley, gear, or power
of the wind, or other convenient economic means according to the position in
which it may be required to work for receiving motion from any auxiliary
power, which will be found in proportion to the quantity of water pumped or
passed through this engine to be much reduced from the amount of power
necessary to be exerted in pumping the same quantity of water by means of
any other pump or hydraulic apparatus now in use.
I have used the term "accumulating" in my title for the reason that as this
bydraulic engine is capable of raising and ejecting a large quantity of water at

page_text: the expense of very little power, so also I am enabled by throttling the outlet
to obtain a column above the final outlet, over which I may apply an air
vessel, so that the delivery may be continuous instead of pulsating. When
such an arrangement may be desired, as, for instance, when using this hydraulic
engine as a ship pump it may be so arranged as to be capable of being used
as a means for extinguishing a fire by the mere application of a suitable hose
and a delivery nose for directing the water.
