PROVISIONAL SPECIFICATION.
Improvements in and connected with Tricycles and other
Velocipedes.
STEPHEN KEMP, of 5 Chryssell Road, North Brixton in the County of Surrey
Inventor and Model Maker, do hereby declare the nature of this invention to be as
follows:-
This my invention relates to a novel method of propelling tricycles and other
velocipedes, by an exactly similar action to rowing in a boat, employing sliding seats
and steering by the feet or steering by the hands and in either method of steering
having a central pull from the front by a single strap, cord, or chain attached to a
T handle the strap or cord passing over a loose pulley above the crownhead of front
wheel and led under the backbone and over the top of motor wheel to which motor
wheel the pulling strap is fixed.
The action for recovering the slack at each pull is obtained by means of a barrel
spring attached to the hub of motor wheel which hub on one side acts as an arbour
for the spring which spring is contained in a barrel and which barrel is fixed to a
hanger from the bridge. The other side of the motor wheel contains a pawl and
ratchet action the ratchet wheel and motor wheel both being loose and free to revolve
on the axle either way when out of gear, and is placed in gear by a carrier capable of
sliding latterally on the axle which axle is provided with feather projections and the
loose carrier provided with corresponding slots for sliding and studs or toggles fitting
in coresponding recesses in loose ratchet wheel is thrown in and out of gear by a
lever switch fixed to bridge.
The sliding seat on traveller running fore and aft is a powerfull auxiliary a chain or
band fixed to front of sliding seat and passing over loose pulley, the other end of
band fixed to an independent motor wheel of smaller diameter arranged the same as
above described for pulling enables the rider to use each movement seperately or
together by pushing and pulling together. The steering by hand is effected by a
lazy tongs arrangement, one end of which lazytongs being attached to T handle and
the fore end attached to vertical quadrent-gear wheel in gear with latteral quadrent
fixed as handlebar on crownhead-to be called the Grace Darling Road Sculler.

page_text: the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This my invention relates to a novel method of propelling Tricycles and other
Velocipedes, by an exactly similar action to rowing in a boat, employing sliding seats
and steering by the feet or hands and in either method of steering having a central
pull from the front by a single strap cord or chain attached to a † handle, the strap
or cord passing over a loose pulley above the crownhead of front wheel and led under
the backbone and over the top of motor wheel to which motor wheel the pulling strap
is fixed, the action for recovering the slack at each pull is obtained by means of a
barrel spring attached to the hub of motor wheels, which hub on one side acts as an
arbor for the spring, which spring is for the purpose of recovering the slack of the
pulling band, at the end of each pull, and is contained in a barrel, which barrel is
fixed to a hanger from the bridge and backbone, which hanger secures a short shaft
or axle, on which shaft or axle, the rowing motor wheel, and seat driving wheel
act. The rowing and sent driving motor wheels are both recessed on the inside, to
hold each a ratchet wheel, the pawls being-loosely fixed to the inner rim of the motor
wheels the seat driving ratchet wheel is fixed to the shaft, and the outer or motor
wheel B is loose and free on the shaft-the rowing inotor wheel and ratchet wheel may
be loose on the shaft, and placed in or out of gear, by the chain wheel which is
provided with studs or cogs at the side, fitting into corresponding recesses in ratchet
wheel and sliding laterally on the shaft secured to it by feather projections-the chain
wheel on shaft in gear with the loose sprocket wheel or carrier or main axle, by a short
chain, which sprocket wheels are provided with studs at side, fitting into corresponding
recesses in the sides of the gear box, and is also grooved in the short hub to receive
the lip of switch; by which means it is instantly, thrown in and out of gear, by
ineans of lever switches fixed to bearing hangers from the bridge.
The sliding seat or traveller running fore and aft is a powerful auxiliary, a chain or
band fixed to front of sliding seat and passing over a loose pulley, the other end of
chain or band is fixed to an independent motor wheel B of smaller diameter arranged
the same as before described for the pulling or rowing action, thus enabling the rider
to use each movement separately or together, by pushing and pulling together.
The steering when sculling is effected by the feet, the footboards being connected
to a short bar, which bar is attached to the pillar of the ordinary handle bar.
This rowing action may be applied to any existing Tricycle with advantage for hill
elimbing, and change of exertion; and by instantly placing the machine in or out of
gear, either process of sculling or of ordinary pedalling may be used separately, or
both together, in this combination machine.
The annexed sheet of drawings will aid more fully to describe my arrangements.
Figure I. Side view of machine.
Figure II. Back view shewing ection of gearing with rowing gear out, and foot
gear in action.
Figure III. Showing the rowing arrangement apart from the foot, and section of
same.
A. is the motor wheel containing the recovering action, consisting of a barrel spring,
and driven by rowing action by means of a driving band or chain attached to motor
wheel and handle D.
B. is the motor wheel driven by the Seat action by means of driving bands K. 1
attached to sliding seat, and recovered by barrel spring the same as A. but
independent.
C. is the seat running on ball bearings on channel wheels on edges of flat traveller.
D. is the pulling handle.
E. is the gear box containing the usual balance gear into the walls or sides of which
box two loose sprocket carriers (marked F. and F. 1) provided with clutches are
inserted for driving.
G. G. the switches inserted in a groove in the sprocket carriers for switching in and
out of gear.
H. are the foot boards for steering when rowing or sculling.

page_text: I. is the ratchet wheel and chain wheel in gear, with loose sprocket wheel F.
J. is the hanger securing short axle containing the rowing gear.
K. is the rowing band for hand use.
K. 1 is the seat band.
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 :-"
First, the spring recovering action, and central pull from the front, by a single
chain or band.
Second, the sliding seat combination as herein shewn.
Third, the method I employ for switching gear in and out of action, substantially
as and for the purpose herein before described, and illustrated by the accompanying
drawings.
