THE NEUTRALIFIC MOTIVE-POWER ENGINE
Year: 1860

page_text: LETTERS PATENT to William Willcocks Sleigh, of 49, Myddleton Square,
in the County of Middlesex, M.D., for the Invention of "THE NEUTRALIFIC
MOTIVE-POWER ENGINE."
Sealed the 14th December 1860, and dated the 20th June 1860.
PROVISIONAL SPECIFICATION left by the said William Willcocks Sleigh
at the Office of the Commissioners of Patents, with his Petition,
on the 20th June 1860.
I, WILLIAM WILLCOCKS SLEIGH, of 49, Myddleton Square, in the County of
Middlesex, M.D., do hereby declare the nature of the said Invention, "THE
NEUTRALIFIC MOTIVE-POWER ENGINE," to be as follows, that is to say :-
It is, as its title implies, to neutralise or counteract in any direction a
portion of the pressure or force produced by an ordinary forcing pump or
other means, on any liquid or fluid put into chambers or cylinders fixed to an
axletree, each cylinder or chamber being furnished with a lid or piston, which
is prevented separating therefrom without being fixed to said chamber or
cylinder, so that the non-neutralised portion of said force or pressure, that is
that portion acting on the surface opposite to said piston or lid, being thus freed
from the counteracting influence of the force or pressure acting on the lid or
piston, may produce a rotatory motion of said axletree, and of whatever may
be attached to it.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Willcocks Sleigh in the Great Seal Patent Office
on the 19th December 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WILLCOCKS SLEIGH, of 49, Middleton Square, in the County of Middlesex,
M.D., send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of June, in the year of our Lord One
thousand eight hundred and sixty, in the twenty-third year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said William Willcocks Sleigh, Her special licence that I, the said William
Willcocks Sleigh, my executors, administrators, and assigns, or such others as
1, the said William Willcocks Sleigh, my 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 "THE NEUTRALIFIC MOTIVE-POWER ENGINE," upon the condition (amongst
others) that I, the said William Willcocks Sleigh, my executors or adminis-
trators, 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 performed, 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 William Willcocks Sleigh, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement, which will be rendered plain by reference to the annexed
Sheets of Drawings and to the numeral figures and letters of reference marked
thereon, similar letters on each Drawing denoting similar parts where such
parts appear at each of the Figures respectively.
DESCRIPTION OF THE DRAWINGS.
At Sheet 1, Figure 1 is a side view, A, the frame for supporting the axle
and the immoveable ring G, Sheet 2; B, the axle, with a longitudinal canal
in its centre, forming a communication between the forcing pump F and the
cylinders or chambers C; C, the chambers or cylinders, firmly fixed to the
axle B; D, guide rods or arms, fixed to the axle, as shewn; E, piston rods,

page_text: supporting the plungers in cylinders C; F, forcing pump, communicating with
the canal on the axle; G, a flat ring, fixed to and supported by the frame by
brackets G'; H, four pinions with teeth, fixed on the immoveable ring G;
I, a ring with teeth on its convex and concave surfaces, and also with steps on
each side of the former row of teeth, as shewn in the end view, Sheet 2,
Fig. 2 this ring is supported by and acts on the pinions H. K, a lesser ring
with teeth on its periphery, firmly fixed to the guide rods or arms D; L,
horizontal levers attached to the rods E; M, a horizontal arm supporting the
cam, as shewn; N, legs, acting on the steps of the wheel I, with a joint h in
the middle of each; O, circular wheel, furnished with teeth to co-operate with
the teeth of the ring I, and with cams on, each side to act on the levers of the
legs N; P, levers, jointed to the legs N and the guide rods or arms D. a,
handle of the forcing pump; b, stuffing box on the axle, fixed to the frame A,
and in which the axle B revolves; c, horizontal levers to adapt the piston
rods to the bent end of the guide rods D, which are bent in order to enable
the said guide rods to pass clear in front of the ring G and the pinions H,
shewn in plan at Fig. 4. The aforesaid engine may be made of such
materials and of such strength and of such a size as an engineer may consider
adequate to the work it is to perform. The forces produced by water, as in
this instance, may be produced by any substance (liquid or solid) capable of
exciting two forces in opposite directions. I put the engine into action in the
following way--The chambers or cylinders C being full of water, I apply
such force as I consider the engine strong enough to sustain, and continue so
to do by repeated strokes of the pump till the piston of the chambers be
resisted and supported. Then motion commences, the wheel I revolving from
right to left, as shewn by the arrows' flight, by the action of the force on the
lid or piston of the chambers, making the legs of the horizontal levers M press
on the said ring; this puts in motion the wheel O, which, by means of its
cams acting on the levers P, alternately straighten and bend the legs N,
producing an action somewhat similar to that of a person on a treadmill. The
pistons and their rods being thus supported and resisted, the force acting on
the surface of the chambers opposite to said pistons, rotate the guide rods, the
axle, and the chambers, as shewn by the arrows' flight. The side motion of
the lever L and roller, in order to give the alternate downward motion to the
legs N, is caused by the motion of the double triangular cam, shewn detached
in two views at Sheet I., marked Z, Z, said cams having teeth around working
into the wheel O.
When I desire to stop the engine, I open a tap, and let the water escape
from the chambers.

page_text: It will appear from the aforesaid description that when pressure is produced
by means of the forcing pump on the fluid or liquid contained in said chambers,
that the pressure will act on the internal surface of the said chambers in all
directions. The piston or lid of each chamber not being fixed or attached
thereto, yet susceptible of motion therein, but prevented separating therefrom
by the aforesaid apparatus or other efficient contrivance, the pressure or force
acting on said piston or lid will not counteract the force acting on the surface
of the chamber opposite thereto, which latter force being freed from the
counteracting influence of the force or pressure acting on the lid or piston
must produce a rotatory motion of the chambers, the axle, and whatever
machinery may be fixed thereto.
Now I claim as my Invention the principle by which the said neutralific
motive power engine acts, and which principle consists in counteracting or
neutralizing one of two forces acting in opposite directions, produced by either
a liquid, fluid, or solid, the force so counteracted or neutralized being in the
direction opposite to that on which it is intended motion should take place.
said motion not depending upon nor being produced by the exit or escape of
any liquid or fluid from said chambers.
In witness whereof, I, the said William Willcocks Sleigh, have hereunto
set my hand and seal, this Seventeenth day of December, in the year of
our Lord One thousand eight hundred and sixty.
Witness,
WILLIAM WILLCOCKS SLEIGH. (L.S.)
