JOSEPH BROEL, of Gravesend, in the County of Kent, Gentleman. "IMPROVE-
MENTS IN OBTAINING MOTIVE POWER, AND IN THE MACHINERY OR APPARATUS TO
BE EMPLOYED THEREIN."
This Invention relates to certain peculiar arrangements and combinations of
machinery or apparatus for obtaining motive power by the force of gravitation
combined with leverage, and consists according to one mode of carrying out the said
Invention of the following arrangement:-A driving wheel of any suitable diameter
is mounted fast upon a horizontal shaft which works in suitable bearings. The rim
of this wheel is extended laterally on one or both sides, so as to project outside the
arms or spokes. Inside the lateral projecting portion of the rim, there are provided
teeth or cogs of any desired pitch and strength. On one or both sides of the driving
wheel there is or are mounted fast on the same driving shaft a small spur wheel or
pinion, which I shall designate the "driving pinion." On a horizontal line passing at
right angles through the centre of the driving shaft, or by preference slightly below
such horizontal line, I mount in suitable stationary bearings an intermediate short
shaft or spindle parallel to the driving shaft, and upon this intermediato shaft I mount
a toothed wheel, which I call the "intermediate wheel." This wheel is made double,
or may consist of a pair of wheels disposed side by side but of different diameters
and made to turn together, the smaller one gearing into the central "driving pinion,"
and the larger one gearing into another toothed wheel, which I call the
gravitation wheel," and which is not mounted on an axle but simply turns round
an imaginary axis of its own situate on the before mentioned horizontal line. This
gravitation wheel" gears on the outer side of its circumference into the teeth or
cogs made in the interior of the lateral projecting portion of the rim of the large
driving wheel. In order to maintain the "gravitation wheel" in its proper position
laterally as regards the teeth of the "intermediate wheel" and those in the rim of
the driving wheel, suitable lateral guiding cheeks or flanges are provided. The
arrangement of gearing above described may obviously be repeated on both sides of
the driving wheel.

The action of the apparatus is as follows:-The "gravitation wheel" exerts its
force upon the rim of the driving wheel at a point in the circumference of the said
"gravitation wheel" farthest removed from the centre of rotation of the driving

page_text: shaft, whilst the corresponding point in the opposite or inner side of the
circumference of the said "gravitation wheel" nearest to the main centre of rotation
by resting upon and being in gear with the teeth of the "intermediate wheel" is
raised, but in a less degree, so as to maintain the "gravitation wheel" always on
the same level. As the weight of the "gravitation wheel" acts upon the inner side
of the circumference of the driving wheel at a point farthest from the centre it turns
the driving wheel and along with it the central "driving pinion." This pinion in
its turn imparts rotary motion to the. " intermediate wheel," which raisos at a point
nearer to the main centre the inner portion of the circumference of the " gravitation
wheel," but in a less degree in proportion as it is nearer the main centre, thus
--maintaining the "gravitation wheel" always on the same level, and since less power
will be required to raise to the proportionate-extont-the inner_point_in_the
circumference of the "gravitation wheel" than is given out by the outer point in its
circumference, it follows that a gain of power will be obtained in proportion to the
weight and diameter of the "gravitation wheel," which power may be utilized or
applied in any well known manner.
Another arrangement of apparatus for obtaining motivo power consists
substantially of a number of radial arms mounted fast on a rotating horizontal
shaft in suitable bearings, each arm carrying in suitable bearings at its outer
extremity a rotating chain pulley or its equivalent, to which pulley there is rigidly
secured a weighted lever, whilst round the same pulley there is passed a pitch chain
its equivalent, which gears into teeth therein, and also gears into corresponding
-teeth-in-a-central_stationary chain pulley of exactly the same diameter. The
several weighted levers should at starting all-be-placed-with-their weights in the
direction in which the apparatus is required to rotate. Now as the radial arms are
rotated by reason of the preponderance of weight on one side of the main centre of
rotation, each of the weighted levers is caused to rotate on its own centre in concert
with or in the same degree as the radial arms by reason of the action of the endless
pitch chains, whereby a continual preponderance of weight and leverage on one side
of the main centre is maintained, which ensures the rotation of the entire apparatus,
the power obtained being proportional to the weight and leverage employed.
