Improvements in Bicycles.
We, ENOCH HAINES, Florist, of 3035, Detroit Street, and ROBERT MONAILAN,
Machinist, of 2907, Detroit Street, Lakewood, in the County of Cuyahoga, and
State of Ohio, United States of America, 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 relates to bicycles, and has for its object to provide increased
speed and greater ease of propelling power, and the invention consists in the com-
bination with the treadle sprocket of a second sprocket coupled by a driving chain
therewith, and having internal gear teeth meshing with a pinion on the hub of
the driving wheel, and the peculiar construction and combination of the frame-
work for mounting said sprocket wheel and pinion.
In the accompanying sheet of drawings:
Figure 1 is a side elevation of a portion of a bicycle having our improvement
attached.
Figure 2 is a rear end elevation of the same, showing our improvement, partly
in section, as applied to the hub of the driving wheel.
Figure 3 is a perspective view of the rear ends of the forks of the framework,
showing the form and construction of the same for supporting the said second
sprocket in connection with the pinion on the hub of the driving wheel.
A is a pinion placed on the end of the hub of the driving wheel in the place of
the small sprocket now used.
B is a sprocket wheel having internal gear teeth, meshing with and operating
said pinion A. The right side branch C of the rear fork is shortened and provided
with a sub-fork of peculiar construction, adapting it for supporting sprocket B.
The said
The inside branch of said sub-fork has a bend d for turning said branch inward
to provide room for sprocket B to be placed on a line with pinion A.
branch is again bent outward at d¹ over the pinion A, and again downward at d
and forms the bearing for the axle of the driving wheel and the pinion.
The right side branch of the side fork E is also provided with a sub-fork, the
inside branch of which is also bent inward at e, in like manner to bend d, and
again outward at e¹ then again at e¹¹ it is bent back and is joined to the end of du
which forms the axle bearing. The two outer branches of sub-forks D₁ and E¹
are joined at their ends and form the outer bearing El for the sprocket B. The
inner branches of the sub-forks are joined by the curved brace b. The inner
bearing for said sprocket B is near the bend e¹ in the inner branch of sub-fork E.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
The combination with the frame and hub of the driving wheel of a bicycle, of
the pinion A, mounted on the hub, the internal geared sprocket wheel B, connected
by chain with the treadle sprocket, and mounted in the frame having the support

page_text: therefor, consisting of the sub-fork, the inner branch having the bends d, d¹ & d",
the sub-fork E, its inner branch having the bends e, e¹ & ell, said inner branches
joined at their ends and forming the axle bearing for the hub and pinion, the
two outer branches of said sub-forks joined at their ends and forming the outer
bearing E for the sprocket B, all constructed and adapted to operate substantially
as herein described and illustrated in the drawings.
