PROVISIONAL SPECIFICATION.
Improvements in or relating to Velocipedes.
We WILLIAM MARKS STREETER of East Beach Street, Boot Maker, and
ELIJAH FRANCIS of No. 1 Castle Hill, Gentleman, both of Hastings in the
County of Sussex do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to construct and adapt a spring motor to a tricycle,
bicycle, or the like in such a manner that when the motor spring is fully wound
up or charged, it is capable of propelling a machine or vehicle with a person upon
it, who can from time to time, conveniently maintain said motor spring in a
desired state of tension without dismounting or losing control of the machine or
vehicle.
In applying our invention say to a tricycle,
We arrange a casing beneath the rider's seat containing a spring and train of
multiplying gear wheels, keyed or otherwise secured to their respective spindles
and supported at each end by suitable bearings.
Upon the last spindle of the series is fixed a sprocket wheel engaging with a
driving chain, that in turn imparts motion to the rear axle of the tricycle by means
of a sprocket wheel of smaller diameter attached to same.
The motor spring is wound up or charged and kept in a state of tension by a
ratchet and pawl in the usual manner. The tension of the motor spring can be
augmented as required by turning the spring spindle by means of a number of
handles radially arranged upon the outside end of the beforementioned spring
spindle, said handles being so disposed relatively to the rider's seat as to be readily
and easily rotated by the right hand of the person riding the machine while his left
hand is free to steer the same.
The starting and stopping of the motor is effected by a lever operating a friction
or other known clutch arranged upon one of the gear spindles.
The usual break applicable to a tricycle is retained but is preferably operated by
the left foot.
Although we have described our invention as it is applied to a tricycle it can be
applied with equal facility and results to a bicycle, in which latter case we prefer
that the winding up or charging of the motor spring should be operated by the
rider's foot.

COMPLETE SPECIFICATION.
Improvements in or relating to Velocipedes.
We, WILLIAM MARK STREETER, of East Beach Street, Boot Maker, and
ELIJAH FRANCIS of No. 1 Castle Hill, Gentleman, both of Hastings, in the
County of Sussex, 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 :-
Our invention relates to certain new and useful improvements in and relating to
velocipedes.
In order that our invention may be clearly understood, we have appended the
accompanying sheet of drawings, in which :-
Figure 1 is a side elevation of a tricycle, embodying our invention.

page_text: Figure 2 is a side elevation, shewing the details thereof detached, and drawn to
a larger scale.
Similar letters of reference indicate corresponding parts in the two views.
Fig. 3 is a plan view of clutch arrangement.
The object of this invention is to construct and adapt a spring motor to a
tricycle, bicycle, or the like in such a manner that when the motor spring is fully
wound up, it is capable of propelling a machine or vehicle with a person upon it,
who can from time to time conveniently maintain said motor spring in any desired
state of tension without dismounting or losing control of the machine or vehicle.
Referring to the drawings, we arrange a casing A beneath the rider's seat S
containing a spring B and train of multiplying gear wheels CD K. M keyed, or
otherwise secured, to their respective spindles, and supported at each end by
suitable bearings.
Upon the last spindle a of the series, we fix a sprocket wheel b engaging with a
driving chain c, which in turn imparts motion to the rear axle of the tricycle by
means of a sprocket wheel d of smaller diameter than that previously mentioned.
The motor spring B is wound up, and kept in a state of tension by a ratchet E
and pawl F in the usual manner. The tension of said motor spring can be
augmented as required by turning the handles H, for which purpose the spring
spindle G has a number of such handles radially arranged upon its outer periphery.
Said handles H are so disposed relatively to the rider's seat S as to be readily
and easily rotated by the right hand of the person riding the machine while his
left hand is free to steer the same.
The starting and stopping of the motor is effected by a stop lever I operating
a friction or other known clutch J arranged upon one of the gear spindles.
The usual brake applicable to a tricycle is employed, and is preferably operated
by the left foot of the rider.
In Figure 2 we show a modification of the winding device consisting of a lever L
upon which is a pivotted pawl P operating the ratchet wheel W, a stop pawl P¹
being added to retain the tension of the spring.
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 :
(1) The combination of a coiled spring B, feeding ratchet E, pawl F, and
handles H, with a velocipede, substantially as and for the purpose hereinbefore
set forth.
(2) The combination with the coiled spring B, ratchet E, pawl F, and handle
or lever H or L applied to a velocipede of a stop lever I, substantially as and for
the purpose herein before set forth.
Dated this 22nd day of June 1892.
