MACHINERY, PARTS OF WHICH IMPROVEMENTS ARE APPLICABLE TO STEAM ENGINES
AND MACHINERY FOR DRIVING PILES;" in which said Lefiers Patent is contained
a proviso that 1. the said Joseph Nye. shall cause a particular description
of the nature of my said Invention, and in what manner the same is in be
to
performed. by an instrument in writing under my hand and seal. to be inrolled
in, Her 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 had, will more fully and at
large appear.

page_text: Joseph Nye, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are fully described and ascer
tained in and by the following statement thereof, reference being had to the
Drawings hereunto annexed, and to the figures and letters marked thereon,
that is to say:-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a section of a double-acting pump; Figure 2 is a horizontal
section thereof, and Figure 3 shews a section taken through the dotted lines a
in Figure Figure 4 is an external view. The peculiarity of this part of
the Invention consists of the peculiar construction and arrangement of the
valve box, and also in the means of giving motion to the piston. a is the
cylinder having a piston b working therein in the ordinary manner.
c is the
valve box, formed or fixed at one side of the cylinder, the valves being one above
the other, and readily to be got at, as is shewn. The valves are of the ordinary
construction. is the induction valve for the lower end of the cylinder; e is
the eduction valve to that end of the cylinder, the valve e opening into the
eduction passage. In the descent of the piston the water or other fluid passes
into the cylinder through the induction valve g, and in the ascending of the
piston the water or fluid passes from the cylinder through the valve 7, into the
eduction way. The piston rod b' is connected by the pin be to the links i. i.
which by means of other pin joints are connected to the series of levers k, l,
which cross each other as shown, and are also connected together by pins or
bolts 1, 1, so that the levers h, k, may assume in working for the descent of the
piston the position indicated by the red lines, and such movement is effected
by the upper pair of the levers k being connected to the shorter ends of the
levers m, m. By this arrangement I am enabled by a comparatively short
motion of the levers m to obtain a long stroke to the piston. The piston rod
guided at its upper end, as is also the parts of the combined levers le, by the
pins and projecting sideways into the fixed guides n, one of which is shown
removed in Figure 4.
Figure 5 shews a side view of a steam engine, constructed with parts
of my Invention applied thereto, the objects of which are to obtain a longer
stroke to a pump than that through which the instrument passes, which
gives motion to the piston rod, and also to obtain a longer motion to an
instrument put in motion by a piston of a steam engine than that piston
itself moves through, and consists of applying a series of cross levers, as is
shewn, a, a, being a series of cross levers which give motion to the piston rod

page_text: of the pump . by means of the beam 6, of the steam engine; but other means
may be resorted to for putting the series of levers into action. is a fixed
pin or axis, which may be carried by any suitable framing, and it will be seen
that a comparatively short motion of the beam will obtain to the piston rod
of the pump a very considerable length of motion through the application of a
system of cross levers a, and in like manner a comparatively long motion will
be given by the application of siniilar means to the piston rode of a steam
engine, a, a, being a series of cross levers; d is a fixed pin or axis; hence a
comparatively short stroke of the steam engine will produce a comparatively
long one to the beam c. and the difference of the length of stroke will depend
on the number of cross bars in the system. I would state that I do noi. claim
the making of the system of levers, nor to any of the parts other than the
application of a series of cross levers, as hercin explained.
Figure 6 shews another arrangement of my improvement in steam engines.
as applied to give motion to the driving shaft or axis of a locomotive engine.
by which, by a short stroke of the engine, it will be seen I am enabled to obtain
a much longer crank motion. The parts are marked with the same letters
of reference as those last used.
Fig. 7 shows another arrangement of my improvement. in steam engines.
and is applicable in giving motion to the propellers of steam vessels. where the
propellers used are of that kind which are moved to and fro by means of rods.
In this arrangement is a cross head. moved to and fro by the piston rod of a
steam engine. such cross head giving motion to two systems of cross bars a, the
one set being contracted and the other expanded each movement of the piston
rod, so that the propellers will be constantly moving in opposite ways; for
this purpose a, a. are the cross levers of the two systems, and d, d, are the two
fixed pins or axes on which they respectively move. The rods g. 9. have
pistons attached thereto, which work in the cylinders g, and by their
alternate ontward movement given an onward movement to the vessel. In this
part of my Invention the novelty claimed is in the application of the systems of
cross levers, a, to a steam engine, so as to give motion to propellers, as
shewn.
Figure 8 shows a side view in section of a pile-driving machine, constructed
according to my Invention. Figure 9 is a sectional back view thereof. a. a, is
the framing, the nature of which is clearly shewn in the Drawing; is the
monkey, which is supported by nippers suspended by a chain cover the pulley d.
the other end of the chain is fixed to the system of cross, levers e, e, the intro-
duction or application of which between the power employed and the monkey
of a pile-driving machine constitutes the peculiar character of this part of my

page_text: ་
Invention. ff. are guide plates for retaining the cross levers e, e, correctly in
place, some of the axes of the cross levers passing between such guide plates;
and they are prevented coming away by such axes having enlarged heads,
which cannot pass between the guide plates /. The lower of the cross levers c
are extended, as shewn by e', e', and they are connected by two links g. 9,
such links being connected by a pin joint to the rack bar h, and the lower
levers e' are connected to the lower framing of the machine by the links i, i.
Motion is communicated to the cross lever by means of the cranked axis j.
which has a pinion affixed thereon, which takes into and moves the rack
bar . By this arrangement it will be found that, the monkey may be raised
and permitted to fall more often with a given power than when using a wind-
lass or barrel for winding up the chain of the monkey, and the general working
of the machine will be otherwise greatly improved. This part of my Inven-
tion consists in the application of a system of cross levers in pile-driving
machines.
In witness whereof, I, the said Joseph Nyc, have herenuto set my hand

thousand eight hundred and fifty-one.
