PROVISIONAL SPECIFICATION.
A New or Improved Gearing for Bicycles, Tricycles, and other
Velocipedes.
JOSEPH EDWIN HOLLOWAY Lambeth House 157 & 159, Westminster Bridge Road
London, Merchant Clothier do hereby declare the nature of this invention to be as
follows:
To each end of the axle of the driving wheel and outside the fork bearings I secure
a small toothed wheel which gears into a larger toothed wheel having the teeth or
cogs pointing inwards and working in a seperate bearing in a small arm attached
to the fork, carrying the spider wheel. The effect is the larger wheel being rotated
gears into the smaller wheel and carries it round in the same direction at a greater
speed, thus dispensing with a chain. As the small wheel in its motion revolves the
spider wheel at any desired speed according to the greater or lesser number of
cogs used in one or both toothed wheels ordinary bicycle cranks or levers may be
used.
Claim. No chain required. A perfect rotary motion capable of being geared to any
desired extent by means of a smaller wheel revolving within a larger wheel and both
moving in the same direction.

JOSEPH EDWIN HOLLOWAY Lambeth House 157 & 159, Westminster Bridge Road
London Merchant Clothier 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 :-
-
To each end of the axle of the driving wheel and outside the forked bearings
I secure a small toothed wheel which gears into a larger toothed wheel having
the teeth or cogs pointing inwards and working in a separate bearing attached to
the fork carrying the spider wheel, the effect is, the larger wheel being rotated
gears into the smaller wheel and carries it round in the same direction at a greater
speed, thus dispensing with any chain. This arrangement applied to both sides of
the fork enables the spider wheel to be geared to any desired extent by simply
increasing the size of the larger cog wheels as compared with the smaller. Ordinary
bicycle cranks or levers may be used.
In order that my invention may be better understood I hereby explain the accom-
panying drawing.
A. is a small toothed wheel keyed to the axle of the spider wheel.
B. A larger toothed wheel gears into the smaller toothed wheel by means of teeth
or cogs cut pointing inwards, causing the smaller toothed wheel to revolve with it in
the same direction at an increased speed.
C. Crank, keyed on to short axle of the larger toothed wheel.
D. Bolt for ball bearing large toothed wheel.
E. Bolt for ball bearing small toothed wheel.
F. Arm or bracket to carry bearing for the large toothed wheel.
G. Bolt by which the said arm is attached to the fork of machine.
G. I. Knuckle joint securing the ball bearing of the smaller toothed wheel.
H. Fork of machine.

page_text: 1. Set nut to adjust ball bearing.
J. Contrivance for keeping the two bearings in proper position.
K. Ball bearing on crank axle.
L. Side plate of large toothed wheel & forming part of short axle to which the crank
is keyed.
To further illustrate my invention I subjoin another drawing showing the gearing
exposed to view.
1. Represents the axle of the spider wheel running in the usual fork bearing.
2. Key by means of which the cog wheel 3. is keyed to the spider wheel axle.
3. The small cog wheel keyed to the axle of spider wheel & caused to revolve by
the larger toothed wheel 4.
4. Is a larger.cog or toothed wheel having the teeth pointing inwards and gearing
into the smaller cog wheel this larger wheel has a solid outer side with a short axle
Braised riveted or screwed to the rim of the said' toothed wheel, this short axle runs in
a seperate bearing attached to the ordinary bicycle fork by a small arm or bracket.
An ordinary bicycle crank being attached to the short axle in the usual way turns the
larger toothed wheel and consequently the smaller at an increased speed, thus gearing
up the spider wheel to any desired extent according to the number of cogs in the
respective toothed wheels.
Having now particularly described and ascertained the nature of my. said
Invention, and in what manner the same is to be performed, I declare that what I
claim is.
1. No chain required.
2. A perfect rotary motion capable of being geared to any desired extent by means
of a smaller wheel revolved by a larger toothed wheel, and both revolving in the same
direction.
