A SELF-ACTING FORCE AND LIFT PUMP FOR RAISING WATER
Year: 1833

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
LUCAS, of Edmond Street, Birmingham, in the County of Warwick, Engraver,
send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Eleventh day of February, in the third year of His
reign, did, for Himself, His heirs and successors, give and grant unto the
said Edward Lucas, His especial licence, sole privilege and authority, that I,
the said Edward Lucas, my exors, adñiors, and assigns, or such others as I,
the said Edward Lucas, my exors, admors, or assigns, should at any time
agree with, and no others, from time to time and at all times during the
term of years therein expressed, should and lawfully might make, use, exercise,
and vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "A SELF-ACTING FORCE AND LIFT PUMP FOR RAISING WATER;"
in which said Letters Patent is contained a proviso that I, the said Edward
Lucas, shall cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed, to be enrolled in His said
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in
and by the same, reference being thereunto bad, will more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Edward Lucas, do hereby declare the nature of my said Invention, and the

page_text: manner in which the same is to be performed, are fully described and ascer-
tained in and by the following description thereof, reference being had to the
Drawing hereunto annexed, and the figures and letters marked thereon (that is
to say):
My Invention consists of an arrangement of apparatus added to an ordinary
force and lift pump, whereby the same is made self-acting, and is intended to
be used in places where a continued stream of water may be had; and the
object of the Invention is, by means of such self-acting. pump, to supply any
compartment or room of a house, or baths, or waterclosets placed therein, or
for fountains, or other uses to which the same may be applicable.
DESCRIPTION OF THE DRAWING.
Figure 1 represents my improvements applied to two working barrels of
ordinary lift and force pumps, A, A, being the barrels or cylinders of the
pumps, B, B, the piston rods, C, C, the pipes descending into a well or other
reservoir of water. D; D, are eduction pipes, which will conduct the water
from the pump to any situation required. E, E, are two weights attached to
the piston rods B, B, and it will be seen that these piston rods are attached by
means of chains to the levers F, F, which turn on bearings on the top of the
framing G. On the other end of the levers F, F, are connected the boxes
H, H, they being suspended on axes, and can consequently turn downwards
for delivering the water at the time they descend. I, I, are two adjusting
weights, capable of sliding nearer to or further from the bearings or axes of
the levers F, F; by means of these weights the levers may be adjusted to the
proper weight for bringing up the boxes after delivering the water. J, J, are
projecting arms from the levers F, F, and by means of the forks on their
upper ends they lift the bent levers K, K, which are hinged to the back of the
cistern L, and have a valve or plug connected by means of a chain or rod.
M, M, are spouts for the water to flow into the water boxes. N, N, are
two levers moving on axes, as shewn in the Drawing; and O, O, are two
weights, which are capable of sliding along these levels, and thus adjust the
weight which the opposite ends of the levers will bear in supporting the water
boxes before overcoming these weights O, O; and there are two catches, which
allow of the frame of the water boxes to pass the end of the levers N in their
ascent, but which prevent the water boxes falling till by their weight they
overcome the levers N.
Figure 2 shews another arrangement of the levers F, F, varying only in
placing the lever N in front of the water boxes, as shewn in this Figure; in
other respects the same letters are used to denote the similar parts.

page_text: Having now described the various parts shewn in the Drawing, I will de-
scribe the manner of their action. Fig. 1 represents one of the levers F up and
the other down, and the water running into the box of that which is up; but so
soon as this box becomes sufficiently heavy to overcome the lever and weight
N, O, and the weight on the piston rod, it will descend, and thereby raise the
piston rod. Meanwhile the box on the other lever F will have discharged its
water, and will have the weight on the piston rod to descend and force out the
water contained in the cylinder or barrel. By the ascent of the levers F, the
plugs or valves which open or shut the spouts will be alternately opened and shut
by the respective projecting arms J, and thus the levers F alternately fall by the
weight of the water in the boxes, and are raised up again by their respective
weights on the piston rods, as will be readily perceived.
I would observe, that I lay no claim to the various parts of which the self-
acting pump is composed, they being separately well known and in use, and
the same may in some degree be varied to suit the convenience of the
situation in which the same are to be placed; but what I claim as my
Invention is the addition of the various parts which work the levers F, F, to
ordinary force and lift pumps, and thereby producing self-acting force or lift
pumps as aforesaid, where a constant run or flow of water may be obtained.
In witness whereof, I, the said Edward Lucas, have hereunto set my
hand and seal, this Eighth day of August,. in the year of our Lord
One thousand eight hundred and thirty-three.
