Improvements in Apparatus for the Production of Motive Power.
I, THOMAS WILLIAM COLE, of Glenholme, Drayton Road, Leytonstone, in the
County of Essex, Engineer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to improvements in the apparatus for the production of
motive power forming the subject of my former Letters Patent No. 23470 of 1892
the object being to obtain an increased leverage without a decrease of speed and
to overcome the resistance to motion offered by the weighted arms when at the
dead points.
According to my invention I locate one end of the shaft carrying the weighted
arm or arms in the face of a fly wheel near the periphery on in a crank in a like
position the other end of the said shaft being supported in a bearing placed in
the axial line of the fly wheel shaft and provided with a crank handle, the said
handle being bent outwards so as to lie parallel with the said axial line. Or the
weighted arms may be connected to the ends of a bar pivoted at its centre upon the
pin of a crank upon the fly wheel shaft. At a right angle to the said bar I arrange
an arm provided with a weight adapted to move outwards by centrifugal force
when the fly wheel and bar are rotated and to swing around the fly wheel shaft.
When I employ a pivoted frame I provide a crank at one end of the shaft
carrying the weighted arms and pivot the frame at a point nearer one end of the
shaft than the other. I also joint a rod to a projection on the frame, the said
rod being attached to the crank pin of a fly wheel, a rod being also employed for
connecting the two cranks together in such a manner that when the fly wheel
crank is at its dead point the weighted arms shall be vertical. The shaft carry-
ing the weighted arms is also cranked at a point in a vertical line with the pivots
of the frame and has attached thereto a connecting rod extending to an oscillating
lever. On the fly wheel shaft is a second crank fixed in the same position as the
first crank but at the opposite end of the shaft. This second crank is connected
by a rod to a second oscillating lever, the said levers carrying a horizontal shaft
having at each end weighted arms arranged in suitable positions. The mechanism
is set in motion by rotating the fly wheel shaft.
In another arrangement I place the shaft carrying the weighted arms in a
universal joint or bearing and its end's pass through slots in rocking bars pivoted
to brackets on the bed plate of the mechanism. Each rocking bar has a connecting
od attached to a crank on the fly wheel shaft.
In the arrangement described in the specification of my said former Patent
for giving an irregular reciprocating motion to the fly wheel shaft I now employ
rotating lever in place of the rocking levers therein described and shewn. In
his arrangement the power can be increased by the leverage without the speed
being diminished by placing the fulcrum of the rocking levers near the ends by

page_text: which they are connected to the cranks on the fly wheel, the shaft carrying the
weighted arms being operated by a connecting rod attached to a crank on the shaft
and to a reciprocating lever to which power is applied. The cranks on the fly
wheel shaft are placed at right angles to each other.

I, THOMAS WILLIAM COLE, of Glenholme, Drayton Road, Leytonstone, in the
County of Essex, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement: —

Figures 8 and 9 are respectively a plan and a sectionel elevation of an arrange-
ment for giving an irregular motion to the fly wheel shaft; and
Figure 10 is a section on the line 10-10 of Figure 9.
Referring first to Figures 1 and 2, I mount the weighted arms a, a upon
pivots b, b on the face of a fly wheel c near the periphery thereof, and I locate one
end of the driving shaft d in the inner end of one of the arms a, eccentric to the
fly wheel shaft e the other end of the shaft d being supported in a bearing f placed
in the axial line of the fly wheel shaft e and provided with a crank handle g, the
said handle being parallel with the said axial line. The inner end of the shaft d
is provided with a crank h having an eye in which is engaged a pin i on a bar j
pivoted at its centre upon the fly wheel shaft e. The weighted arms a, a are respec-
tively connected to the ends of the bar j by the said pin i and a pink which pass
through slots 1, in the said arms. At a right angle to the bar j I arrange a
weighted arm m adapted to move outwards by centrifugal force when the fly
wheel c is rotated and to swing around the fly wheel shaft e. The arm m is jointed
at n to a crank o on the shaft d and at p to a link q which is pivoted to a pin r
T
on the face of the fly wheel c.
The
power applied to the crank handle 9 is transmitted by the shaft d and the

page_text: crank h, to the pin i of the bar j. The said pin being at a greater distance from
travels at a greater
the axial line of the fly wheel shaft e than the crank handle
The
speed than, but with the same power as applied to, the crank handle. The pin i
on the bar jis kept in its radial position by the centrifugal action of the weighted
arm a connected thereto. The inner end of the shaft is kept in alignment with
the said weighted arm by the centrifugal action of the other weighted arm.
resistance to motion offered to the rotation of the inner end of the shaft d is by
the arrangement hereinbefore described converted into power to assist in rotating
the fly wheel. The joint pin at n on the crank o being situated in the axial line,
it will be obvious, that an outward pressure applied to this crank pin at a right.
angle will be transmitted to the pin i of the bar j in addition to the power applied
to the crank handle g. I produce this pressure by centrifugal action by the
employment of the arrangement of weighted arm m and link g as hereinbefore
described. To enable the apparatus when rotated at a reduced speed, to have an
increased outward pressure to keep the weighted arms in alignment I advan-
tageously arrange a frame Figure 2 consisting of four jointed arms a³ two
opposite angles of the frame being arranged to press beneath the weights of the
weighted arms a, a while the other two angles are connected by tension springs 63
to a block 3 loose on the fly wheel shaft e.
When I employ a pivoted frame as illustrated in Figures 3, 4 and 5, I provide
a crank s on the shaft t carrying the weighted arms a, a and pivot the frame u at
points nearer one end of the shaft than the other. I joint a rod w to the
crank s, the said rod being attached at one end to a crank a on the fly wheel shafty,
and at the other end to a slide z. When the crank x is at its dead points the
weighted arms are vertical.
By this arrangement the rotation of the shaft y while causing a rotation of the
shaft t also causes the frame u to reciprocate on its pivots v. The shaft t is also
provided with a crank a¹ at a point in a vertical line with the pivots of the
frame and has attached thereto a connecting rod b₁ connected to the upper end
of an oscillating lever c¹. On the fly wheel shaft y is a second crank d¹ fixed in
the same position as the crank a but at the opposite end of the shaft. This crank d¹
is connected by a rod el to an oscillating lever f¹ fulcrummed on the same shaft as
the lever c', the said levers c¹ and f¹ carrying a horizontal shaft g¹ having at each
end weighted arms h¹, h¹. The mechanism is set in motion by rotating the
shaft y.
In some cases I provide the shaft t with cranks i, ¹ carrying eccentric weighted
discs j, j to assist the rotation of the shaft t.
I would observe that in the mechanism hereinbefore described with reference to
Figures 3, 4 and 5 the parts a¹, b¹, c¹, d¹, e¹, f¹, g¹ and h¹ can if required be omitted.
In another arrangement illustrated in Figures 6 and 7 I place the shaft t carry-
ing the weighted arms a, a in a universal joint or bearing k¹ and its ends pass
through slots, in rocking bars m¹, m¹ pivoted to brackets n¹, n¹ on the bed
plate o of the mechanism. Each rocking bar m¹ has a connecting rod p¹ attached
to a crank q on the fly wheel shaft r¹.
In the arrangement described in the specification of my said former Patent for
giving an irregular motion to the fly wheel shaft, I now employ (as illustrated in
Figures 8, 9 and 10) a rotating lever or crank s in place of the rocking levers pro-
vided for that purpose. In this arrangement I employ rocking levers ¹, t carry-
ing at one end the shaft u¹ to which the weighted arms a, a are fixed, and the power
is increased by the leverage without the speed being diminished by placing the
fulcrum of such levers near the ends by which they are connected with their
cranks w, w¹ on a shaft w² through the medium of connecting rods a¹, x¹, the pin
of one of the cranks w¹ engaging with a slot y¹ in the lever s¹. The fly wheel
shaft 2 is eccentric to the shaft 3. The shaft u¹ is operated by a connecting rod a
attached to a crank 62 on the said shaft and to a reciprocating lever c³ to which
power is applied for starting the apparatus. The cranks w¹, w₁ are arranged at
right angles on the shaft w.
