PROVISIONAL SPECIFICATION.
An Improved Arrangement of Driving Gear for Bicycles and Front
Driving Tricycles.
I, BERNARD WAREING, of 68, Northwood Street, in the City of Birmingham,
Jeweller, do hereby declare the nature of this invention to be as follows:--
This invention consists of the hereindescribed improved arrangement of driving
gear for bicycles and front driving tricycles.
In carrying out my invention as applied to a bicycle or a front driving tricycle
the axle of the front.or driving wheel projects at each side beyond the bearings
which are formed with or attached to the fork, and on each of the projecting ends
of the axle I fix a small spur pinion. The said fork is prolonged below or at one
side of the bearings of the driving wheel axle and to each of these prolongations
I fix an outwardly projecting stud these studs being parallel with the said
driving wheel axle. Free to revolve upon each of these studs I provide an
internally toothed wheel which gears with the corresponding spur pinion on the
driving wheel axle and to these internally toothed wheels the cranks or the pedals
are fixed.
The rider by the pedals turns the said two internally toothed wheels fixed
thereto and their motion is transmitted to the spur pinions and the driving wheel
which revolves at a higher speed than the pedals and in the same direction, the
internally toothed wheels and the spur pinions being so proportioned as to give the
necessary gearing up" of the machine.
€6
The said internally toothed wheels are by preference each furnished with an
outer disc plate next the cranks so as to exclude dirt and prevent the rider's
trousers getting rubbed by the wheel.
The said internally toothed wheels and the spur pinions may either be made
wholly of metal or alloy or one or both of them may have teeth of wood or other
suitable substance morticed therein.
My invention above described can be similarly applied to cycles driven by
compressed air or by electricity or other motive power.

COMPLETE SPECIFICATION.
An Improved Arrangement of Driving Gear for Bicycles and Front
Driving Tricycles.
I, BERNARD WAREING, of 68, Northwood Street, in the City of Birmingham,
Jeweller, 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 :-
This invention consists of the hereindescribed improvements in driving gear for
use in bicycles and front driving tricycles for transmitting power and rotary motion
from the pedal axle to the driving wheel axle thereof.

CSCITING my THY CHICION by referring to the accompan
Fig. 1 is a side elevation of a bicycle with my said invention applied:
ப UII
Fig. 2 is a cross sectional elevation through the driving wheel axle of the same
on an enlarged scale shewing my improved driving gear in detail;
Fig. 3 is a sectional side elevation of the same;
Figs. 4 and 5 represent details of the said driving gear and
Figs. 6 and 7 each shew a modified form of a part of the same on the same scale
as Figs. 2 and 3.
The same letters of reference indicate the same or corresponding parts in all the
figures.
In carrying out my invention the axle A. of the front or driving wheel B
projects at each side beyond the ball bearings C1 C2 which are attached to (or
formed with) the fork D, and on each of the projecting ends of the axle A. I fix
a small spur pinion which are respectively marked E' E². The end parts D¹ D³ of
the fork D in which are the bearings C₁ C² are by preference made separate from
the main portion D of the fork and are prolonged at d' either below the bearings
(Figs. 2, 3 and 5) or at one side of the bearings (Fig. 6) or above the bearings
(Fig. 7). These prolongations d' are as shewn turned backwardly towards the
centre of the driving wheel axle A and to each of these prolongations I fix an
outwardly projecting stud F these studs being parallel with the driving wheel
axle A. Free to revolve upon each of these studs I provide an internally toothed
wheel (marked respectively G1 G2) which gears with the corresponding spur
pinion E or E2 on the driving wheel axle A and to the bosses g₁ of these
internally toothed wheels G G² the cranks H' H2 are respectively fixed. The
bosses g of the wheels G1 G2 are provided with internal ball bearings but as these
are commonly used for other parts of velocipedes so as to diminish friction they
require no description here.
The rider by the pedals and cranks H1 H2 turns the two internally toothed
wheels G¹ G² fixed thereto and their motion is transmitted to the spur pinions Et E2
and the driving wheel B which thus revolves at a higher speed than the pedals
and in the same direction, the internally toothed wheels G¹ G2 and the spur
pinions EE being so proportioned as to give the necessary "gearing up
the machine.
of
The wheels G G³ may be constructed with pin teeth ² as shewn upon my
drawing or the internal teeth of the wheels G₁ G2 may be made in any other well
known manner.
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-
1. In a front driving bicycle or a front driving tricycle the improved con-
struction and arrangement of parts constituting the driving gear for causing the
driving wheel to revolve faster than the cranks and in the same direction, consisting
of two externally toothed spur pinions such as E' E' fixed to the ends of the
driving wheel axle and two larger internally toothed wheels fixed respectively to
the two cranks and gearing with the said spur pinions and arranged to revolve on
studs fixed to the lower parts of the fork, all arranged and operating substantially
as set forth.
2. In combination with a driving gear of the kind denoted under Claim 1 for
a front driving bicycle or a front driving tricycle the hereindescribed improved
construction of the fork formed with the prolongations turned backwardly
towards the centre of the driving wheel and provided with the studs F for the
internally toothed wheels and the cranks to revolve upon substantially as set forth.
3. In a driving gear of the kind denoted under Claim 1 for a front driving
bicycle or for a front driving tricycle, the combination of the pinions E' E', the

page_text: rotating driving wheel spindle A and driving wheel, the internally toothed
wheels G1 G2, the studs FF carried by the fork prolongations d¹ d¹, and the
cranks H H all arranged and operating for the purpose and substantially as
hereinbefore described.
