TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," Southampton
Buildings, London, Doctor of Laws, send greeting.

page_text: WHEREAS I am in possession of 'an Invention for "AN IMPROVED
MOTIVE-POWER ENGINE TO BE OPERATED BY THE PRESSURE OF WATER, STEAM, OR
COMPRESSED AIR, AND CAPABLE OF USE AS A PUMP, BLOWING ENGINE, OR GAS
EXHAUSTER," and have petitioned Her Majesty to grant unto me, my
executors, administrators, and assigns, Her Royal Letters Patent
for the same, and have made solemn Declaration that it has been
communicated to me from abroad by Messrs. Wyss and Studer, of
Zürich, Switzerland.
NOW KNOW YE, that I, the said George Haseltine, do hereby declare
that the following Complete Specification, under my hand and seal, fully
describes and ascertains the nature of the said Invention, and in what
manner the same is to be performed, in and by the following statement,
reference being had to the accompanying Drawings forming part of
this Specification :-
This engine is designed chiefly for working machinery hitherto driven
by manual labor in towns and other industrial places where steam
power is either too expensive or prohibited because of its danger, and
other inconvenience.
The introduction of waterworks and conduits with high-pressure water
for the domestic supply of towns has made it desirable to obtain a con-
venient motive power for driving lithographic and printing presses, wood
and iron working machinery, pumps for distillery purposes, hoists, and
other machinery not requiring very great power. Its application is
however not limited to town industries, but may be used advantageously
in larger proportions for natural falls of water from 20 metres upwards, 1
at least where the water does not contain pebbles or rough sand. It
may further be applied for raising and forcing liquids such as sewage for
cleaning pits, as fire pumps, or for contractors' purposes.
The cylinder of this improved engine is oscillating, deriving its motion
in the ordinary way by the crank being directly connected to the head
of the piston rod, and being supported on its trunnions by fixed bearings
cast in one piece, and thereby directly connected with the crank shaft
bearings. These two double bearings are bolted firmly upon a strong
foundation plate, supporting also the air vessel on its after part. They
are further connected by two stays, as shown. The cylinder bears at
both right and left sides flat faces turned and adjusted truly rectangular
.

page_text: to the axis of its trunnions. Into these faces open the ports of the two
water passages contained in the lower part of the cylinder body com-
municating at their other ends with the bore of the cylinder. Adjusted
truly to them and so held up as to be easy but tight against the said
cylinder faces are two boxes, one at cach side, which receive in the first
place the water from the conduits and distribute it by a corresponding
port contained in its face alternatively to the two cylinder ports, and con-
sequently fore and aft of the piston, causing the same to reciprocate,
guided by the crank. A fly wheel is provided to overcome the dead
points which occur at each end of the stroke. The water which has
performed its work is expelled by the returning piston back through its
passage, and enters the above-named boxes through two separate ports
to the right and left of the admission port, whence it flows through
suitable conduits to the drain pipe into the sewer or other receptacle
whence it may be used again.
Figure 1 is a plan partly in horizontal section of an engine con-
structed according to this Invention. Figure 2 is a side elevation of the
same.
Figure 3 is partly an end elevation and partly a transverse section on
the line A*, B*, Figure 1.
Figures 4 and 5 shew portions of the said engine detached.
Like letters indicate the same parts throughout the Drawings.
A is the admission port in the distribution box which admits the water
alternatively to the cylinder ports D, E. Supposing E to be in cor-
respondence with A as in the Drawing, D corresponds with the exhaust
port B in the box. From this position the piston now moves from right
to left expelling the exhaust water through D and B, and down through
the opening L which is common to both B, E, into any suitable conduit
leading to the drain. On the return of the piston the like action takes
place in the opposite direction.
.
The screws a are for the purpose of setting and fixing the boxes I, K,
in their proper positions in reference to the cylinder ports. By means of
the set, screws.b.they are screwed: slightly up to the cylinder to make a

page_text: tight joint between their faces, and still allow of free motion of the
cylinder between the boxes.
If the engine is used as a water pressure engine the water under
pressure enters at F and divides beneath the air vessel in two branches
G, H, which are made in preference of india-rubber hose; the air vessel t
is then placed at any suitable distance from the machine, that is to say,
· it is not necessary it should stand on the bed plate. The said two
branches conduct the water to the two boxes I, K, and through them
into the cylinder and through the same to the drain as before described.
t
If the engine is used as a steam or air motor, the air vessel is of course ]
omitted, and the branches I, K, made of copper, the other parts being the
same as above described...
If the said Invention is to be used as a pump, the suction pipe is
attached at L and the delivery pipe at F, the machine moving in reversed
direction driven by a belt or by manual labour.
In the appiication of this Invention as a steam pump two engines are
connected in opposite direction, their piston rods being attached to onc
crank. One cylinder receives steam and imparts its motion to the other
which acts as the pump.
The ports and passages may be made of any section required to suit
the purposes to which the said Invention is to be applied by increasing
or diminishing the length of radius of the ports and passages.
1
In any case two such engines may be placed side by side, the cranks
being then coupled at right angles to avoid dead points.
By retaining the same area of ports and passages and without
increasing the frictional faces, the stroke of the piston may be increased
to any convenient extent, thereby reducing the number of revolutions
with the same relative piston speed, the advantage of this is apparent in
the reduction of the strain in conduits resulting from the cut-off at the
dead points twice in every revolution.
By the employment of elastic pipes in the two branches leading from
the air vessel to the cylinder, these strains are further reduced, these
pipes yielding under the internal stress to some extent and consequently
diminishing them and allowing them to be taken up more easily by the

page_text: air vessel. The avoidance of these strains which produce an unpleasant
knocking noise is of great importance as they are produced at the
expense of the useful. effect of the water power. No friction exists
between the sliding faces of the cylinder and its distribution boxes, that
is to say, a balanced pressure exists between them by reason of the set
screws 6 being tightened up exactly to the amount of the water pressure
tending to force the boxes off the cylinder. This balancing taking place
from right and left, there is no kind of friction brought upon the
cylinder other than that due to the thrust of the piston and resisted by
the cylinder in its journals.
The frictional faces being flat and the ports cut squarcly to them they
can at any time be readjusted in case they should wear on account of
impure water, the pitch of the ports, remaining unaltered with returning
faces, which is totally different with machines of curved faces underneath
the cylinder, the facilities for lubricating these faces are so far greater
than in other engines that no part of the said improved engine has to be
lifted bodily up to allow access to them, all that is required is to slacken
the set screws to allow the lubricating fluid being poured in between
the faces whilst every facility is afforded for taking all parts to pieces for
thorough cleaning.
Furthermore, the said improved engine possesses the advantages of the
greatest possible solidity and facility of construction and repairs, the
absence of any kind of valves and its adaptability for various purposes,
combined with the possibility of cheap production, facility of erection,
and its very slight want of attention when working. The useful effect
obtained with this engine is within 8% of the power of the water
column.
Having thus fully described the said Invention as communicated to
me by my foreign correspondents, and the manner of performing the
same I wish it understood that I claim,―
First. The arrangement of the cylinder and crank shaft bearings at
cither side in one bracket common to both.
Second. The introduction of the water from opposite sides to the
cylinder, thereby obtaining a pressure of water on the same perfectly
1. counterbalanced.

page_text: Third. The employment of elastic pipes or conduits between the air
vessel and the water distribution or inlet boxes.
Fourth. The loose water distribution box adjustable to the cylinder
ports in the direction of the longitudinal axis of the cylinder.
In witness whereof, I, the said George Haseltine, have hereunto
set my hand and seal, this Twenty-seventh day of October,
in the year of our Lord One thousand eight hundred and seventy-
three.
