IMPROVEMENTS IN OBTAINING AND APPLYING WATER MOTIVE POWER
Year: 1861

page_text: LETTERS PATENT to Thomas Pedrick, of 5, Park Place, Brixton, in the
County of Surrey, Machinist, for the Invention of "IMPROVEMENTS IN
OBTAINING AND APPLYING WATER MOTIVE POWER."
Sealed the 14th February 1862, and dated the 19th August 1861.
PROVISIONAL SPECIFICATION left by the said Thomas Pedrick at the
Office of the Commissioners of Patents, with his Petition, on the
19th August 1861.
I, THOMAS PEDRICK, of 5, Park Place, Brixton, in the County of Surrey,
Machinist, do hereby declare the nature of the said Invention for, "IMPROVE-
MENTS IN OBTAINING AND APPLYING WATER MOTIVE POWER," to be as follows:-
I use the force of water set in motion by pistons or plungers, which may be
-acted upon by manual power, or otherwise, which I purpose to effect by the
use of a driving axle connected to a beam or crosshead, whereby the pistons
or plungers (also connected therewith) working in two water cylinders or
pumps of equal size are duly acted upon; the said cylinders being each of
them connected to other or working cylinders by a tube or pipe of considerably
less bore than the respective areas of the cylinders. Of course instead of four
cylinders, 8 or 12, and so on, may be used if thought expedient. The cylinders
to have the necessary appliances for rendering the pumping action effective,
and communicating the power obtained to the purposes required.
The above is a description of the nature of this Invention, the details
whereof might probably be varied in practice.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
PEDRICK, of 5, Park Place, Brixton, in the County of Surrey, Machinist,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of August, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Thomas Pedrick, Her special licence that I, the said Thomas
Pedrick, my executors, administrators, and assigns, or such others as I, the
said Thomas Pedrick, executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN OBTAINING AND APPLYING WATER MOTIVE POWER," upon
the condition (amongst others) that I, the said Thomas Pedrick, my execu-
tors or administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Thomas Pedrick, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
(No. 1.) The nature of the said Invention, as hath been heretofore
intimated in and by the Provisional Specification left and recorded on appli-
cation for said Letters Patent, consists in the use and adoption in manner
hereafter set forth of the arrangements hereafter described, that is to say:-
I use the force of water set in motion by pistons or plungers (which pistons or
plungers may be put and kept in work by hand, by steam power, or the fall or
force of water,) which I purpose to effect by the use of an axle or shaft (or of
axles or shafts), whereby the pistons or plungers connected therewith, and
working in water cylinders or pumps of equal size, are duly acted upon, the

page_text: said cylinders being each of them connected to other cylinders by a tube or pipe
of considerably less bore than the respective areas of the cylinders. Of course,
instead of four cylinders, there may be a greater number, eight or twelve, for
instance, if thought expedient. The cylinders to have the necessary appliances
for rendering the pumping action or motions of the pistons or plungers
effective, and communicating the power obtained to the purposes required.
(No. II.) Having thus described the nature of the said Invention, I now
proceed to describe in what manner the same is to be performed or put in
practice, wherein I shall refer to the illustrative Drawings accompanying this
Specification by the words, figures, and letters marked thereon, and herein-
Figure 1, elevation; Figure 2, end elevation; Figure 3, plan view of an
engine constructed according to my said Invention; this particular arrange-
ment being suited to locomotive purposes, and may be adopted as an engine
for other purposes.
A denotes sole plate; B, framing for the cylinder gear; C, vertical cylinders;
D, horizontal cylinders; E, rods of pistons, plungers, or rams, both for the
horizontal and for the vertical cylinders; Ex, guides for the rods of vertical
cylinders bolted on to the top parts of the said vertical cylinders (C), these
cylinders being open at the tops; F, connection slings for connecting the rods
E with disc wheels (G); H, fly wheel. For the horizontal cylinders (D) the
connecting rods are marked I, and the guides and guide blocks for the
same I. J, cranks; K, crank shafts; L, brasses for connecting rods;
M denotes the pinion on fly wheel shaft which gears with the disc wheels (G);
N, pipe and cock for letting on the force of water from the pump, or
otherwise.
This engine is put in operation by letting on the water through the
cock (N) aforesaid into the horizontal cylinders, and when these are filled,
then motion is to be imparted to the fly wheel, which will, through the action
of the pinion on its axle, give motion to the disc toothed wheels gearing
therewith. Said disc wheels being connected to the connecting slings by the
cranks which are set on their centres, so that upon the disc wheel nearest the
pinion describing one quadrant of the circle, the other disc wheels describe
other and different quadrants of the circle; the effect of which is, that whilst
in one pair of cylinders (that is, one horizontal and one vertical cylinder,) the
vertical piston is pressed down. The one so situate in the Drawings being E',
the next at the right hand E2, being three-fourths stroke or throw, E³

page_text: being one-fourth stroke, and E' at top of cylinder. Hence one piston has
arrived at the bottom of its stroke, another piston is three-fourths towards the
bottom, and the others at the same time are one at the top and the other three-
fourths towards the top, and this produces a corresponding effect on the pistons
in the horizontal cylinders, that is, causes them to be in the reverse positions
to the pistons in the vertical cylinders, by reason that we have as aforesaid a
pipe or duct of considerably smaller bore than the areas of the cylinders
between each vertical and each horizontal cylinder, and thus the continuous
motion of the engine is maintained. For locomotion, driving wheels should
be set on-the-crank-shafts K, and-for other purposes riggers and other suitable
appliances might be adjusted to said crank shafts.
(No. III.) Having now particularly described and ascertained the nature
of the said Invention, and in what manner the same is to be performed, I
declare that I claim the improvements in obtaining water motive power as
I have set them forth in the outset, marked No. I. of this my Specification
thereof; but that I lay no claim to the constituent parts of the arrangements
herein described, except as forming part of this Invention.
In witness whereof, I, the said Thomas Pedrick, have hereunto set
my hand and seal, this Eighteenth day of February, in the year of
our Lord One thousand eight hundred and sixty-two.
