Year: 1884

page_text: INUTIDIONAL DI MUITICATION.
I ALEXANDER MELVILLE CLARK of the firm of A. M and Wm Clark of
53 Chancery Lane in the County of Middlesex, Fellow of the Institute of Patent
Agents do hereby declare the nature of the said Invention for "AN IMPROVED
HYDRO-MECHANICAL MOTOR" to be as follows:-
This Invention relates to an improved motor based on the application of the
property of fluids to raise or float bodies of less specific gravity than themselves,
with a force which is directly proportionate to the difference of density of these
bodies and the liquid in which they are immersed.
In order that the Invention may be more readily understood I will proceed to
describe the same by way of example with reference to the accompanying Drawing
in which Figure 1 shews a longitutional vertical section of the apparatus and
Figure 2 a cross section taken on line 1, 2 Figure 1.
In constructing this improved motor two cam surfaces R R are fixed vertically
each upon a framing Z or against a wall. The point of these cams of greatest
radius is below and to the left of the axis and the point of least radius is to the
right and on the same diameter. The cams are provided on their inner peripheries
or faces with a guide groove. A motor wheel having a number of arms or spokes,
there being ten in the example shown, is mounted upon a horizontal shaft formed
in one with said arms and passing freely through the axis of the cams which serve
as bearings for the said shaft, the latter being prolonged beyond the framing for
the purpose of transmitting the power. The wheel is thus contained between and
close up to the two cams. The wheel arms the length of which is determined by
the power to be developed by the apparatus, are each provided at their extremities
with a bellows A, B, C, D, E, G, H, J, K, L these arms each pass through a tube T
(termed an air tube) fixed to the upper surface of the bellows and the free ends of
said arms being fixed to the inner side of the bellows so that the latter are expanded
by causing their outer side to move towards the axis of the moter wheel. The
bellows are each composed of a flat outer and inner side. The outer side which is
pierced with air holes, is provided with air tubes M so called having guides for the
rods B which traverse the same longintudinally, as represented in plan and
Price R71

page_text: perspective view in Figures 3 and 4. So far the cams and the noter wheel are
independant of each other and in order to connect them, the outer sides of the
bellows are provided near their outer edges with rods S bolted at one end to said
bellows and carrying at their opposite ends, nearest the centre of the wheel, a
friction roller which travels in the guide grooves of the cams.
The bellows are
connected together by either one or two bands attached to their outer sides. The
apparatus thus consists (1) of two fixed cams (2) of a motor wheel (3) of a bellows
carried on the end of each arm of the motor wheel, the whole mounted upon a
single shaft. The apparatus thus constructed is to be placed in either still or
running water, such as a pond, river, sea, tank &c. or any other liquid the level
of which should nearly reach the top of the air tube T which is in the lowest
position and the apparatus immediately commences to operate. The cams to which
the outer sides of the bellows are connected by the rods S owing to their form and
position keep the bellows which are on the right hand full open to those which are
on the left and at bottom fully closed so that the bellows enter the water to the
left in a closed position (remaining closed until they pass the vertical line through
the shaft) while those to the right of the vertical line pass through the water in an
expanded condition and consequently the buoyant power of the water causes them
to rise out of it and thus set the whole apparatus in motion, as the exit of the
"expanded bellows, causes those which are closed to enter and become expanded in
turn immediately they have passed beyond the vertical line and so on in succession
the motion continuing as long as may be desired. The power obtained from this
improved motion depends upon the form of the cams and upon the number and
dimensions of the bellows.
The materials to be employed in constructing the apparatus and the details of
construction would be dependent upon the power required to be obtained from the
apparatus.

53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "AN IMPROVED
HYDRO-MECHANICAL MOTOR" 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 an improved motor based on the application of the
property of fluids to raise or float bodies of less specific gravity than themselves,
with a force which is directly proportionate to the difference of density of these
bodies and the liquid in which they are immersed.
In order that the Invention may be more readily understood I will proceed to
describe the same by way of example with reference to the accompanying Drawing
in which Figure 1 shews a longitudinal vertical section of the apparatus and
Figure 2 a cross section taken on line 1. 2. Figure 1.
In constructing this improved motor two cam surfaces R, R, are fixed vertically
each upon a framing Z or against a wall. The point of these cams of greatest
radius is below and to the left of the axis and the point of least radius is to the
right and on the same diameter. The cams are provided on their inner peripheries
or faces with a guide groove.
A motor wheel having a number of arms or spokes B (there being ten in the
example shown) is fixed upon a horizontal shaft passing freely through the axis of
the cams which serve as bearings for the said shaft, the latter being prolonged
beyond the framing for the purpose of transmitting the power. The wheel is thus
contained between and close up to the two cams.
The wheel arms, the length of which is determined by the power to be developed
by the apparatus, are each provided at their extremities with a bellows A, B, C, D,
E, G, H, J, K, L. These arms each pass through a tube T (termed an air tube)
fixed to the inner side of the bellows and the free ends of said arms are fixed to the
outer side of the bellows so that the latter are expanded by causing their inner side
to move towards the axis of the motor wheel.
The bellows are each composed of a flat outer and inner side as shown in plan
and perspective view in Figures 3 and 4. The inner side is pierced with air holes
over which are fitted the air tubes T (so called) having guides for the arms B
which traverse the same longitudinally.
So far the cams and the motor wheel are independant of each other, and in order
to connect them the inner sides of the bellows are provided near their outer edges
with rods S bolted at one end to said bellows and carrying at their opposite ends
nearest the centre of the wheel a friction roller which travels in the guide grooves
of the cams. The bellows are connected together by either one or two bands
attached to their outer sides.
The apparatus thus consiste (1) of two fixed cams (2) of a motor wheel and (3) of
a bellows carried on the end of each arm of the motor wheel, the whole mounted
upon a single shaft. The apparatus is to be placed in either still or running water,
such as a pond, river, sea, tank &c. or any other liquid, the level of which should
nearly reach the top of the air tube T when in the lowest position and the
apparatus immediately commences to operate. The cams to which the inner sides
of the bellows are connected by the rods S owing to their form and position keep
the bellows which are on the right hand fully open and those which are on the left
hand at bottom fully closed so that the bellows enter the water, to the left in a
closed position (remaining closed until they pass the vertical line through the shaft)

page_text: while those to the right of the vertical line pass through the water in an expanded
condition and consequently the buoyant power of the water causes them to rise out
of it and thus set the whole apparatus in motion, as the exit of the expanded
bellows, causes those which are closed to enter and become expanded in turn
immediately they have passed beyond the vertical line and so on in succession the
motion continuing as long as may be desired.
The power obtained from this improved motor depends upon the form of the
cams and upon the number and dimensions of the bellows.
The materials to be employed in constructing the apparatus and the details of
construction would be dependent upon the power required to be obtained from the
apparatus.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is -

constructed of two fixed cams Rand of a motor wheel each arm B of which is
connected at its extremity with a bellows or extensible capacity substantially as
herein shewn and described.
2nd In a motor, adapted to work in water or other liquid, the employment of

putting the interior of each bellows in constant communication with the external
air substantially as described.
3rd In a motive power apparatus adapted to work in water or other liquid, the
combination of the bellows connected to arms B of the motor wheel and united
