PROVISIONAL SPECIFICATION.
Improved Apparatus for Producing Motive Power.
I,D UNCAN MOLEAN 85 Hudson Street North Shields Joiner (Jurneyman) do
hereby declare the nature of this invention to be as follows:-
A Principal of Perpetual Motion in the working of a Machine by leverage pendu-
lums acting under a balance. Letter a is the shaft passing through letter 6 which is
the carriage. c is a bush projecting past each side of the carriage on which the
pendulums swing D the pendulum e a wheel on top end of pendulum which runs in a
groove on the under side of the balance weight then the whole of the tonnage is
balanced by 4 Pendulums when the pendulums are at an angle of 45° to the perpen-
dicular centre line & the tonnage is then balanced by the beam as is shown in
figure 3 & the same Principal is repeated to the same shaft with cranks at right angles.

COMPLETE SPECIFICATION.
Improved Apparatus for Producing Motive Power.
I, DUNCAN MCLEAN, 85 Hudson Street North Shields, Joiner, (Jurneyman) 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:-
On the carriage A for the shaft there is a bush projecting from each side on which
the two leverage pendulums B B swing. This bush extends beyond the outer side of
the pendulums to get a bearing & also to get a guide or flange, which along with the
check that is on the carriage forms the groove on the bush on which the pendulums
swing, passing through this the shaft C is connected with a fly wheel & also with
cranks D these cranks are connected with rods which are connected to the balance
weight E the pendulums have wheels F on the top ends which run in a groove on the
underside of the balance weight. Heavy weights in the form of nuts are attached to
the bottom ends of the pendulums, a thin bolt passes through the nut and pendulumi
to keep the nut secure. There can be one or more pendulums under one balance
weight as in the case of four I have the pressure two of them acting under ths of
the width of the balance weight by seeing that every other one runs in the same
direction. There are two rocking beams connected by rods to the ends of the two
balance weights and one connected to the centre, on the top side of this centre
beam there rests a heavy wheel movable by means of a screw which serves as a brake
or stopping power. There are columns to guide these weights perpendicular, on the
top of these columns there is a shaft passes from one end of the balance weight to the
other with a fly wheel on it and also cranks with rods to be connected to each end of
the balance weight. Where there is a want of space the apparatus will work without
the beams, or fly wheel which is over the beams. The main shaft can be carried either
above or below the pendulum upon the perpendicular centre line, which will do away
with the bush that is on the carriage when required and leave a solid shaft for the
pendulum to swing on, The way in which power is produced is as follows :—
The whole of the weight that is bearing on top end of pendulum is overcome by a
majority added to the lower end. The pendulum swing in a semicircle, the radious of this
semicircle is the diameter of the circle in which the crank shaft revolves a repetition
of cranks to this same shaft divided equal around the circle, with a pair of pendulums
for each crank will bring the last pair nearer the first pair to the horizontal line when
they are in their only equilibrium.

page_text: 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 adaptation of lever pendulums to a self acting apparatus for producing
motive power by the combination of such lever pendulums so adjusted or arranged
by their connection with a crank shaft provided with more or less cranks so as
continuilly to drive or revolve such shaft to which gearing or belting can be connected
for the porpose of driving or propelling all classes of machinery or vihicles or for
pumping purposes.
(2) The annlication of a brake for stopping the machine.
