Improvements in and connected with Electric Generators for Cycles
and other Vehicles, and a Device for Attaching and Adjusting
same.
JAMES MOORES and HENRY OLIVER FARRELL, both Electrical Engineers, of
15, Hanging Ditch, Manchester, in the County of Lancaster, do hereby declare
the nature of this invention to be as follows:-
Our invention relates to an improved mechanical electric generator, driven from
the wheel or other revolving part of a cycle or other vehicle, for the purpose of
producing current to light an incandescent lamp. And a device for attaching
and adjusting the said electric generator to the vehicle.
In carrying out our invention we use a permanent magnet field of suitable
form. Between the poles of the magnet or magnets, we mount, on suitable bear-
ings, an armature of any suitable form and winding but we prefer to use a shuttle
or Siemens armature.
.
We employ suitable collectors to collect the current.
We enclose the parts herein before described, in a case.
We extend the armature spindle beyond one of the sides of the said case, and
attach to the said spindle extension, a pulley.
In using our invention this pulley is brought into contact with the rim of the
wheel, or other revolving part of a vehicle, which transmits its movement to the
said pulley and causes the armature to revolve, producing current, that is con-
ducted to an incandescent lamp.
We may make the pulley herein before mentioned in one piece, of india rubber
or other suitable substance. Or we may construct the said pulley of metal or other
suitable material, with a groove round its circumference, in which said groove,
we slip a band or ring of india rubber or other suitable suitable material. So that
the said band or ring can easily be detached from the said pulley, when it is worn
out, & replaced by a new one.
To increase the friction grip of the herein before mentioned pulley, on the rim
of wheel or other revolving part of the vehicle, we corrugate the contact surface
of the said pulley, in one or more directions, or we may make the said surface
with a number of raised points on it. Or we may incorporate emery or grit in
the substance forming the said contact surface.
For the purpose of attaching to, and adjusting our electric generator on the
cycle, or other vehicle, we fix to the electric generator, a block of metal with a
hole through same in an approximately vertical direction. We attach a similar
block, with a hole through it in an approximately horizontal direction, to the
body or frame of the vehicle, adjacent to the revolving part, with which it is
desired to bring the before mentioned pulley in contact. We then take a rod of
steel or other suitable material, & bend it to a right angle approximately.
One end of this rod slides in the hole through the before mentioned block on
the vehicle, giving our horizontal adjustment. Over the other end of the said
rod, slides the before mentioned block, on the electric generator; giving the

page_text: adjustment in a vertical direction. When the desired adjustment is obtained, the
electric generator is held in that position by means of screws, screwing into the
two before mentioned blocks, & pressing against the before mentioned rod; or by
any other suitable means.
Improvements in and connected with Electric Generators for Cycles
and other Vehicles, and a Device for Attaching and Adjusting
same.
We, JAMES MOORES and HENRY OLIVER FARRELL, both of 15, Hanging Ditch,
Manchester, in the County of Lancaster, Electrical Engineers, 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:-
Our invention relates to an improved mechanical electric generator, driven from
the wheel or other revolving part of a cycle or other vehicle, for the purpose of
producing currents (say) to light an incandescent lamp, and a device for attaching
and adjusting the said electric generator to the vehicle.
In carrying out our invention we use a permanent magnet field of suitable
form. Between the poles of the magnet or magnets we mount on suitable bear-
ings an armature of any suitable form and winding but we prefer to use a shuttle
or Siemens armature. We employ suitable collectors to collect the current.
We enclose the parts hereinbefore mentioned in a case.
We extend the armature spindle beyond one of the sides of the said case, and
attach to the said spindle extension, a pulley.
In using our invention this pulley is brought into contact with the rim of the
wheel or other revolving part of a vehicle, which transmits its movement to the
said pulley and causes the armature to revolve, producing a current that is con-
ducted to an incandescent lamp.
We may make the pulley hereinbefore mentioned in one piece of india rubber
or other suitable substance. Or we may construct the said pulley of metal or
other suitable material with a groove round its circumference in which groove we
slip a band or ring of india rubber or other suitable material, so that the band
or ring can easily be detached from the said pulley when worn out, and replaced
with a new one.
To increase the friction grip of the herein before mentioned pulley on the rim
of wheel or other revolving part of the vehicle, we corrugate the contact surface
of the said pulley in one or more directions. Or we may make the said surface
with a number of raised points on it. Or we may incorporate emery or grit in
the substance forming the said contact surface.
For the purpose of attaching to and adjusting our electric generator on the
cycle or other vehicle we fix to the electric generator a block of metal with a
hole through the same in an approximately vertical direction. We attach a similar
block with a hole through it in an approximately horizontal direction, to the
body or framework of the vehicle, adjacent to the revolving part with which it is
desired to bring the before mentioned pulley in contact. We then take a rod of
steel or other suitable material and bend it to a right angle approximately.
One end of this rod slides in the hole through the before mentioned .block on

page_text: the vehicle giving our horizontal adjustment. Over the other end of the said
rod slides the before mentioned block in the electric generator, giving adjustment
in a vertical direction. When the desired adjustment is obtained, the electric
generator is held in that position by means of screws screwing into the two before
mentioned blocks, and pressing against the before mentioned rod, or by some other
suitable means.
In order that our invention may be readily understood we have annexed hereto
a sheet of drawings illustrative thereof.
Fig. 1 is a side view and Fig. 2 a plan of so much of a cycle lamp cycle wheel
rim and fork as is necessary to illustrate our invention. Fig. 3 is a partial view
of the cycle wheel rim and the driving pulley of the dynamo which lights the lamp.
a is the rim of the wheel, and a¹ the tyre, a is part of the fork to which the
block or bracket a³ is attached.
6 is the casing of the dynamo, 6¹ is the reflector shown fitted thereto or formed
therewith, 6 the incandescent lamp fitted therein. The cycle lamp may of course
be separate from the dynamo if preferred.
:
c is the spindle or shaft of the dynamo which extends outside the casing b and
carries an armature of any suitable kind the dotted lines at c¹ Fig. 1 indicate
the magnet or magnets. The shaft c is driven by a small pulley c² as before
described, running in contact with and rotated by the rim a of the wheel (see
Fig. 3).
This pulley is preferably made of metal with a grooved periphery into the
groove of which a detachable rubber band may be sprung as shewn, and is also
preferably roughened as herein before described on its periphery to increase its
grip or friction on the rim a.
b
The necessary contact is obtained by adjusting the casing by the rod dd;
the part d thereof slides horizontally in the block or bracket and is set therein
by a suitable screw at, the part d' carries the block 6ª on the casing 6 which can be
set thereon by the screw b
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. An electric generator adjustable vertically and horizontally on a cycle or
other vehicle, so as to be actuated by a pulley from the inside of the rim of one of
the wheels, substantially as hereinbefore described.
2. An electric generator actuated by a pulley from the inside rim of one of
the wheels of a cycle or other vehicle the said pulley being grooved at its edge
and provided with a detachable rubber ring substantially as herein before
described.
3. An electric generator actuated by a pulley from the inside rim of one of the
wheels of a cycle or other vehicle the said pulley being provided with a roughened
or specially prepared friction surface by corrugating or otherwise substantially
