We, ABRAHAM DAVIDSON and BERNHARD GOLDSTEIN, both of
Thorpdale Road, Hornsey, in the County of Middlesex, do hereby
declare the nature of the said Invention for "IMPROVED APPARATUS FOR
OBTAINING MOTIVE POWER." to be as follows:-
This Invention consists in the construction of apparatus in which the
combined operation of air, levers, and weights is employed for the
purpose of obtaining motive power, the same being applicable for all
-purposes of locomotion whether on land or water, and also for actuating
machinery generally for which such power is required. The whole of
the apparatus is supported by a bed plate which is provided with four
or any other desired number of travelling wheels, the same being respec-
tively coupled together by means of combination levers which are
continued from guide wheels mounted on the bed plate, and which work
on pivots, the latter being governed by a regulating wheel by means of
a chain attached to the pivots, whereby the latter are moved to and fro
so as to allow another wheel to be inserted between the guide wheels

page_text: and the driving wheels in order to reverse or stop the motion of the
apparatus by means of the driving wheel. The driving wheel is
actuated by a "motion pole," consisting of a bar of iron or other suitable
metal pivoted at the centre in suitable bearings on a triangle of iron
which is firmly bolted to two upright columns respectively bolted or
fixed to the bed plate. Motion is given to the "motion pole" by means
of "travellers" which are connected to the respective ends of the pole,
one being placed on each side thereof. The travellers respectively work
in guide boxes which are bolted to the bed plate, and containing at the
lower part thereof the pivots or bearings for the axle of two concentric
wheels by which upward-and-downward motion is conveyed to the two
travellers. On the axle of the concentric wheels are three cranks, the
exterior two of which are worked by means of a series of weights and
levers, whilst the other or centre crank is employed for the. purpose of
working the air pump herein-after mentioned. Sets of weights and levers
are provided, each one being attached at two points to cranks working
on shafts, and at a third point which is fixed to a cross bar; any desired
number of these levers and weights are worked at one end of the appa-
ratus and a corresponding number at the other end, so as to obtain an
accumulative power by which the apparatus is actuated. The power is
in the first instance brought into action by wheels at the rear end of the
apparatus, and is accumulated and communicated to the front set of levers
and weights by means of chains attached to two sets of cranks placed
above the apparatus.
The said last-mentioned wheels, which may be termed " perpetual
motor wheels," are furnished with weights, springs, and wings, the
wings being acted upon by the air which is caused to impinge upon the
same, and the perpetual motor wheels with their weights and springs
constituting fly wheels which exert their greatest power during only
one part of their revolution. Two ordinary fly wheels are attached to the
sets of weights and levers in the front of the apparatus. An air pump
is placed below the before-mentioned central crank, whose office it is to
work the same; such pump having a weight on its upper side, which
latter is connected to the crank by means of a chain. The said chain is
carried upwards and over a pulley and returned downwards and fastened
to the upper side of the air pump, thus working the pump by means of the
centre crank. In the rear end of the air pump is inserted a tube which
leads to a suitable receptacle provided for the reception of the air, and

page_text: from which receptacle two pipes furnished with stop-cocks are carried
upwards, so that when the air is allowed to issue therefrom the same
will constantly impinge upon the wings of the before-mentioned
wheels.
At the rear end of the apparatus is placed a small air pump to be
worked by hand by the driver or attendant, by which a sufficient
amount of air can be caused to impinge upon the before-mentioned
wings, so as to set the wheels to which they are attached as before
mentioned in motion, when the apparatus will become self-acting.
The necessary "brake" appliances are used in connection with the
apparatus, but the same being well known and understood by persons
conversant with mechanism need not be more particularly referred to.
