PROVISIONAL SPECIFICATION.
Improvements in Hydraulic Engines.
I JOHN WILLIAMS 52 Cae'r Chwarel Caellwyngrydd near Bangor Quarryman
do hereby declare the nature of this invention to be as follows:-
The nature of my invention is comprised chiefly in the easy manner of letting out
the water out of the cylinder; by which means I gain additional strength and
velocity. For this purpose I make use of a valve having four water ports; two of
which are to receive the water into the cylinder, and the other two, to let out the
water from the cylinder. The valve also contains a slide, which is a flat, smooth plate,
with one water port in the centre for the purpose of letting the water into the
cylinder. I construct the cylinder in such manner that the water is received into
it, through two water ports, and the waste water let out through two other different
water ports which are at the side. In my construction of my engine I make
use of two cylinders, fly-wheel together with a specific number of cog-wheels; and
with the co-operation and attachments of these I design the machine to work six
pumps, more or less.

JOHN WILLIAMS 52 Cae'r Chwarel Chaellwyngrydd near Bangor in the County of
Carnarvon Quarryman. I do hereby 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 :-
This invention relates to improvements in the construction of hydraulic engines. In
order that my invention may be well understood and carried into practice I will
describe the same with reference to the accompanying drawings in which similar letters
are used to indicate corresponding parts thereof. I exhibit my invention in drawings
upon two sheets.
To start with I construct a valve parts of which are described
and shewn in Figures 1, 2 and 3. In Figure 11 shew the slide A together with a
water-port B the middle of the same. D in Figure 2 shews the lower part of
upon
the valve. E and E' are water-ports through which the water enters.
water-ports through which the water is let out.
G and G' are
In Figure 3 exhibit the several parts of my invention put together and opened
at the middle for the purpose of shewing my invention inside. I is the upper part
of the valve. A the slide. D is the lower part of the valve. F is the cylinder
which is made up of one piece with the water passages J; J1 and the ports H in it.
K is the piston which is made up of one piece with a grooved flange around it for
the purpose of packing leather.
When the engine works the water enters through the ports V which are shewn
in Figure 4 and going into the vacuum W Figure 3; thence through port B of
the slide and through the port E in bottom of the valve into the water passage J and
the
thence again into the cylinder F, working upon
K.
piston
I show the course of the ingress and egress of the water by means of the arrows.
In this figure too I shew that the ports G. G1 of the valve answer to the ports H, H¹
of the cylinder, the purpose of and through which the waste water run out.
When the piston K moves to one end of the cylinder the slide too moves in the
same direction by means of its connection with the excentric T Figure 5, and the
rods T which are shewn in Figure 4. After the slide has thus acted the ports G¹

page_text: close and the ports G open to let out the waste water. The port E too closes and
the port E opens to let the water into the cylinder through the water passage J and
acting upon the piston in the same way as before. After thus describing the action
of the water in one valve and one cylinder it must be understood that the same fact
relates to Figure 4, in which the invention is shewn double.
These
The action of the piston backward and forwards effect upon the piston rods K¹ to
which the connecting rods M, M' are connected as shewn in Figure 4.
connecting rods are again connected with the cranks N, N' and the cranks again
secured and fixed in the axle of the fly-wheel S. The axle is shewn in Figure 5
on which too I fix and secure two cog-wheels Q, Q' which are to act with the
two, cog-wheels R, R. On the axles of these two wheels I fix and secure four
cranks N N N N ; to these cranks I join the rods of four pumps which are shewn
in 02 03 04 08 and the two other rods 0 and 0₁ are joined to the cranks N
and N¹. The rods and cranks are shewn in Figures 4 and 5 which are six in
number.
More or less pumps may be attached as necessity may require. These six pumps
are worked by two cylinders F and F upon the sides of which I fix and secure the
valves which are shown in X Figure 4. I fix them thus in order to give an easy
passage to the water from the cylinder.
On the ports G and G¹ Figure 4 I fix a pipe to carry the waste water down into
the trough of the pumps as shewn at P, P Figures 4 and 5.
W are steps up the platform Y on which the engine driver stands.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed 1 declare that what 1
claim is :-
1. The slide A together with the water-port B in the same.
2. The construction of the valve together with the water ports contained therein.
combined and working substantially as and for the purpose herein before described and
illustrated in Figures 2, 3, 4 of the accompanying drawings.
3. In conjunction with the said valve and the slide A with the water port B, the
cylinder F with the water ports contained therein and the piston K as and for the
purpose herein before described and illustrated in Figure 3 of the accompanying
drawings.
4. My improved engine constructed arranged and working substantially in the
manner and for the purpose herein before described and illustrated in the accompanying
drawings.
