PROVISIONAL SPECIFICATION.
An Improved Means of Distributing the Motive Force, and Reversing
Fluid-pressure Engines.
JOHN GEORGE MOORE, Engineer 21 Dundas Street Monkwearmouth Sunderland
do hereby declare the nature of this invention to be as follows:-
This invention relates to that class of engine, having two cylinders, with cranks
at right-angles to each other, & consists chiefly-of a lever fixed at one end to
piston rod & having its other end connected to slide rod of opposite cylinder.
The fulcrum of this lever is carried on a bracket which is guided by a slot at right
angles to piston rods by a slot in the said bracket. By moving bracket to one end
of slot, the valve lever will move the slide valve in the same direction as the
piston rod to which lever is attached, & thus move engine in one direction. By
moving bracket to other end of slot, the fulcrum of slide lever will be on other side
of slide rod-& consequently slide valve will be moved in an opposite direction to the
first position, and thus the motion of engine is reversed.

COMPLETE SPECIFICATION.
An Improved Means of Distributing the Motive Force, and Reversing
Fluid-pressure Engines.
JOHN GEORGE MOORE Engineer 21 Dundas Street Monkwearmouth Sunderland
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 that class of engines having their cranks at right-angles
to each other, and consists principally as shown by the accompanying sheet of
drawings, where, in all the figures the same part referred to by the same
letter.
Fig. 1. is a longitudinal plan of engine, with the valve chests on the inner sides of
engine.
R. is one piston-rod to which is fixed the lever B, the said lever working on a
fulcrum carried on the bracket A. C is a valve lever fixed to the piston-rod R¹,
and likewise working on a fulcrum carried by bracket A. S. S. are studs screwed
into bedplate L, and guide the bracket A at right angles to the piston rods R.
and RV and V₁ are the distributing valves. F and F₁ are the valve rods,
P and P pistons. H. is the reversing handle. The action is as follows:-
When the bracket A is in the position as shown by Figure 1. the fulcrum of the
lever B. is at the point E, and the distance from the centre E. to centre of rod Fi
is such as to give the necessary travel to the valve V₁, likewise the fulcrum of the
lever C is at the point D. giving the necessary travel to the valve V. in the
position shown, the piston P. is beginning its stroke and consequently the valve V1
is in the proper position for admitting the working force into the piston P¹. The
piston being at half stroke, the valve V is in the proper position for admitting the
working force to piston P. The engine will thus run in one direction.
By moving the handle H. from position 1. to position 3. the fulcrums of the
levers B and C. carried on the bracket A. are moved to the centres D' and E¹,
thereby converting the levers B and C. to levers of an opposite order to the
previous position, thus the travel of the valves V and V₁ are reversed and the

the handle H. to position 2. the fulcrums of the levers B. and C. will coincide with
the centres of the valve-rods F and F, and thus the valves V and V will remain
stationary.
Fig. 2. is an end elevation, showing arrangement of valve levers.
Fig. 3. is a side view showing bracket A. carrying the fulcrum of slotted levers B.
and C. and showing studs S. S. through bedplate L.
Figs. 4. and 5. show the arrangement of levers, when the valve chests are on the
outsides of engine. The action is the same as in Figs. 1. 2. 3.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The means of controlling the distribution of the working force of the engine
by the combination of the slotted levers B. and C. with the piston rods R and R
substantially the same as shown by the Figures 1. 2. 3. 4. 5.
2. The reversal of the engine by means of the slotted bracket A. carrying the
fulcrums of the levers B. and C.
