We, JAMES COPHLAND and HENRY MONTGOMERY COPELAND, of Brunswick Line,
near Wanganni, in the Provincial District of Wellington, New Zealand, Farmers,
do hereby declare the nature of this invention to be as follows:-
A is the hub, spindle, or axle; or the made up portion of a hub, spindle, or axle
that carries wheel B of a velocipedo or bicycle.
B is the pedal, cog, chain, or band wheel of a velocipedo or bicycle.
On the outer face, or on the side of A is cut one, or more racks, or slots C
perpendicular on one face, and sloping to nothing on the other.
Let into the inner face, or fixed on the side of B is one, or more pawls D),
D is pressed by spring E into the rack or slot (.
When B is moved forward, or A backward, D entches on the perpendicular face
of C, which causes A & B to move in the same direction.
When B is moved backward, or A forward, pawl D passes over the sloping face of
rack or slot C.
Or on the inner face, or on the side of B is cut one, or more racks or slots C
perpendicular on one face, and sloping to nothing on the other.
Let into the outer tace, or fixed on the side of A is one, or more pawls D
pawl D is pressed by spring E.into rack, or slot, C.
When is moved forward, or A backward, the perpendicular face of C catches
on D which causes A & B to move in the same direction.
When B moves backward, or A forward, the sloping faco of rack or slot C passes
over pawl D.
A & B can be converted into a solid by a bolt or snib being shot from A into B,
or from B into A.
The foregoing combination to be applicable to all pedal, cog, chain, or band wheels
in a velocipede or bicycle.
By this invention the feet of the rider the treadles, and the chains of a bicycle,
may remain stationary whilst tho bicycle travels on impelled by its own momentum.

An Improved Pedal Action for Velocipedes and Bicycles.
We, JAMES COPRLAND and HENRY MONTGOMERY COPELAND of Brunswick Lino,
near Wanganui, in the Provincial District of Wellington, New Zealand, Farmers,
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:-
The object of this invention is to provide mechanism whereby ridors of velocipedes
may keep their feet at rest upon the pedals and thus hold the pedals and driving chain
from revolving whilst the machine continues its progress.
The object of the invention is carried into effect by making the hub of the driving
or rear wheel somewhat similar to existing forms. The sprocket wheel, however, is
made to fit so that it may revolve upon a boss of the hub. Indontations are cut in
the boss and pawls are pivotted in the sprocket wheel to engage with the indentations.
Whon travelling in one direction the pawls engage with the indentations to drive
the machine, but when revolving in the other direction the pawls merely slide up
the inclined faces of the indentations and allow the inachine to travel with unimpeded
movoment.
In order that our invention may be most easily understood by one skilled in the art
to which it appertains we will now proceed to describe the same, reference being had to
the drawings accompanying our Provisional Specification in which,
Figure I is a sido view of a hub fitted with the improvement, shewn partially in
section.
Figure 2 is an end view shewing the pawls and indentations.
Similar letters refer to similar parts.
Referring to the views, (a) is the hub of a rear or driving wheel having a boss (b),
collar (c) and flanged nut (d), so fitted together that when in position they form a
groove wherein sprocket wheel (1) may revolve. Pawls (g) are pivotted in sprocket
wheel () and may engage with indentations (4) cut in boss (6). When the sprocket
wheel is revolving in the direction shewn by the arrow one of pawls (g) will engage
with one of indentations (4), which are so spaced in relation to oach other that the
total number of times the pawls may engage with the indentations is equal to twice
the number of indentations.
Should it be desired for any reason to make the sprocket wheel practically solid
with the hub, this may be accomplished by shooting bolt () as shewn in Figure 1,
when the collar (c), sprocket wheel () and nut (d) will be locked together. The
bolt is held to its work by its spring (") which is flat in section and passes through
flanges (a') and (a 2) as guides, and is retained by one of its recesses (2) engaging
with rib (a 3). The spring further is used for covering oil hole (a 4) to excludo dirt.
It is obvious that the positions of the pawls and indentations may be reversed
and the pawls pivotted upon the hub and indentations cut in the sprocket wheel.
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,
The improved pedal action consisting of mechanism, constructed, arranged and
operating substantially as hereiubefore set forth and illustrated on the accompanying
drawing.
