PROVISIONAL SPECIFICATION.
Improvements in or in connection with Lamps for Bicycles,
Tricycles, Vehicles, and all kinds of Rolling Stock.
I JOHN EDWARD BAILY WALKER of 24 Paxton Road All Saints Birmingham
in the County of Warwick Traveller, do hereby declare the nature of this invention
to be as follows:-
My invention relates to lamps of all kinds used for cycles vehicles and rolling
stock generally and consists of producing the light for same by electricity generated
by means of a dynamo or stored in "supplies which may be situated in any
convenient position on the cycle or other vehicle.
"
When a dynamo is used to generate the current of electricity for the lamps the
electric communication will be established between the driving power of the cycle
or other vehicle and the dynamo and the lamps by means of suitable connections or
gearing, the electric current being controlled by the amount of power alotted to the
dynamo by the driving capacity of the cycle or other vehicle.
The fact of propelling the cycle or the motion of the vehicle obviously creates
power and by the communication existing between the driving medium and the
dynamo the required amount of electricity is generated for the lamps.
Or instead of a dynamo "supplies" may be used for the storage of the electricity
the "supplies" being situated in a suitable position in direct communication with
the lamps.
By these means a very efficient method is obtained for the above named purposes
whereby a brilliant light is afforded.

COMPLETE SPECIFICATION.
Improvements in or in connection with Lamps for Bicycles,
Tricycles, Vehicles, and all kinds of Rolling Stock.
I, JOHN EDWARD BAILY WALKER of 24 Paxton Road All Saints Birmingham
in the County of Warwick Traveller 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 :-
"
My invention relates to lamps of all kinds used for cycles vehicles and rolling
stock generally and for other purposes where similar means may be applied with
like effect, and consists in producing the light for the same by electricity generated
by means of a dynamo which may be placed in any convenient position on the
cycle vehicle, or other situation or stored in a "supply and attached where
required. When a dynamo is used to generate the current of electricity the electric
communication is established between the driving medium of the cycle or other
vehicle etc. and the dynamo and thence to the lamp by means of suitable connec-
tions or gearing, the electric current being controlled by the amount of power
allotted to the dynamo by the driving capacity afforded. When adapted to
bicycles or other cycles the fact of propelling the same obviously creates power
and by the communication existing between the driving medium and the dynamo,
the required amount of electricity is generated.

page_text: I will proceed to describe my invention more fully with the aid of the accom-
panying drawings in which I have illustrated my method in connection with a
bicycle.
Referring to the drawings in which similar letters of reference upon the several
figures relate to similar parts.
Figure 1. is a view of a bicycle with my improvements in connection therewith.
Figure 2. is an enlarged view of the lever with pulley or roller which form a part
of my arrangement.
Figure 3. enlarged view of lever and roller as attached to stay.
Figure 4. shews a rack for use in connection with the lever.
Figure 5. an elevation of a dynamo with a pulley or roller connection.
Figure 6. is a front elevation of a lamp with front removed and Figure 7. side
elevation of same.
Let A represent the dynamo which is connected to the stay B or other part of
the framework of the machine by screws, bolts or other attachment at C. Situated
above the dynamo A is a lever D suitably pinned or pivotted to the said stay B
and having at its lower end-which may be formed with two arms D¹, D', like
a fork-a grooved pulley or roller E which revolves in the forked arms and is
located in close proximity to the tyre F of the driving wheel G of the machine,
the upper part of the lever terminates in a handle D³ to manipulate the
action of the same, a band H of catgut or other suitable material passes over
the pulley or roller E on the lever and also over a second pulley or roller I situated
upon the dynamo.
A rack or other suitable arrangement is attached to the stay B to engage and
retain the lever D in position either in or out of contact with the driving wheel,
similar in action to a carriage brake and rack arrangement.
From the dynamo A and in connection therewith is an electric wire or cable K
which by preference is made to pass up within the tubular stays B, B', see dotted
lines, and finally is carried into an incandescent lamp L into contact therewith.
Apertures are made in the stays B, B1, B2, to admit of the cable being passed
therein, and out again to the lamp.
When required a supply A¹ may be situated upon the machine as shewn or where
convenient.
OPERATION.
In order to generate the electricity for the light the action is thus.
The lever D upon being pressed down by the hand of the rider causes the pulley
or roller E thereon to be brought into immediate contact with the tyre F of the
driving wheel G, the lever with its roller being kept to its bearing by the rack J,
this contact of the pulley or roller E with the driving wheel establishes communi-
cation therewith, hence the motive power produced by the propelling of the machine
is conveyed to the dynamo A by the aforesaid band H and pulley or roller I and
the current of electricity generated in the dynamo passes up the electric wire or
cable K and into the lamp L as shewn.
Or the supply A' for the storage of the electricity may be used in addition to a
dynamo in which case the electric wire or cable passes from the dynamo through
the supply and thence to the lamp.
Or instead of a dynamo being attached, the supply A', of the required capacity
is previously charged and connected to the machine by any suitable attachments or
device, the electric wire or cable passing from the said supply to the lamp.
I may state that although I have illustrated one special form of lamp, any
suitable kind may be adopted for the purpose.
When the electricity is generated upon the machine according to the rate at
which it may be driven so accordingly is the intensity of the light produced,
as when travelling at a rapid pace extra power is transmitted to the dynamo, as
will be readily understood.
A suitable case or covering shewn by dotted lines M, M', is provided to enclose

page_text: the dynamo and also the supply which may consist of papier maché or other suitable
material and is connected to the machine in any convenient manner.
As an alternative method, the dynamo may be situated so that the motive-power
shall be transmitted from the axle of the driving wheel instead of from the tyre as
described whichever may be found most advantageous to produce the desired result,
in which case the lever and connections or other method will be so arranged to
suit the construction.
In a similar manner my improved system when applied to other vehicles and
rolling stock generally and for other like purposes will be so adapted for the
individual requirements that the necessary power may be produced by the driving
medium in whatever capacity in connection with a dynamo to produce the electricity
or by means of supplies as aforesaid.
I do not confine myself to the exact details of the construction or the particular
arrangement or arrangements as herein set forth, as my invention may be carried
into effect in various ways to meet different requirements, provided always that the
main principle of the adaptation of the electric light for such purposes as I have
stated be maintained.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
Firstly. In connection with the lamps for bicycles and other cycles the application
and adaptation of electricity as a medium for producing the light for the said lamps
as set forth or by other suitable means, for the purpose.
Secondly. In connection with the lamps for bicycles and other cycles the
construction and arrangement of the several parts constituting my invention and
consisting of the attachment of a dynamo to the said bicycle or other cycle with the
accessories of lever D, pulley or roller E, rack J, the connecting band I, upon the
said dynamo, all operating in relation to each other in manner and for the purpose
substantially as herein set forth described and illustrated.
Thirdly. In lamps of all descriptions for bicycles, tricycles, vehicles, and all kinds
of rolling stock generally and for other like purposes, the adaptation of electric
light for the said lamps, and in the means whereby the same is produced; as set
forth and described.
Fourthly. I claim the general construction and arrangement of parts as herein
set forth alone or in combination or other similarly acting means for the purpose of
producing the light for the lamp or lamps by electricity from a dynamo or from
supplies.
