PROVISIONAL SPECIFICATION.
Improvements in and relating to Velocipedes.
I, WILLIAM PATMORE of the Pelham Cycle Works, Wimbledon in the county of
Surrey, Cycle Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to a tandem cycle or velocipede capable of being converted
into either a <<
Cripper" type tricycle or into a rear-driving safety bicycle, and it
consists in attaching in any convenient position to the frame of an ordinary tricycle
of the "
Cripper" type, an upright stem in the rear of the stem carrying the seat
pillar. This upright stem is attached to the frame of the tricycle by a transverse
joint of any approved construction. This upright stem carries lugs to form centres
by which a frame carrying a rear-driving wheel, similar to the rear frame of a rear-
driving safety bicycle, is attached in the rear of the tricycle, thus making a tandem
velocipede with four wheels, the front one of which is the steering wheel and the
other three are driving wheels, the front pair being driven indirectly through a pedal
crank axle by the front rider, and the rear wheel indirectly through a pedal crank
axle by the rear rider. A transverse handle bar for the rear rider is carried in the
upright stem hiuged to the tricycle frame.
To convert the machine; into a rear-driving safety bicycle, the rear part carrying
the single driving wheel, and the front fork carrying the steering wheel, are detached
from the other part of the machine, and then connected together by the usual steering
head or joint.

COMPLETE SPECIFICATION.
Improvements in and relating to Velocipedes.
I, WILLIAM PATMORE, of the Pelham Cycle Works, Wimbledon, in the County
of Surrey, Cycle Manufacturer, 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 :-
My invention relates to a tandem cycle or velocipede capable of being converted
into either a Cripper" type tricycle, or into a rear driving safety bicycle, and it
consists in attaching in any convenient position to the frame of an ordinary tricycle
of the "Cripper" type, an upright stein in the rear of the stem carrying the seat
pillar. This upright stem is attached to the frame of the tricycle by a transverse
joint of any approved construction. This upright stem carries lugs to form centres
by which a frame carrying a rear driving wheel, similar to the rear frame of a rear-
driving safety bicycle, is attached in the rear of the tricycle, thus making a tandem
velocipede with four wheels, the front one of which is the steering wheel and the
other three are driving wheels, the front pair being driven indirectly through a
pedal crank axle by the front rider, and the rear wheel indirectly through a pedal
crank axle by the rear rider. A transverse handle bar for the rear rider is carried
in the upright stem hinged to the tricycle frame.
To convert the machine into a rear-driving safety bicycle the rear part carrying
the single driving wheel and the front fork carrying the steering wheel, are detached
from the other part of the machine and then connected together by the usual steering
head or joint.

page_text: And in order that my Invention may be thoroughly understood, I now proceed
to describe the accompanying drawings thereof, reference being had to letters and
figures marked thereon.
Figure 1., represents a view of the rear-driving portion D, of a rear-driving safety
bicycle, connected to the transverse handle bar F carried in the upright stem J and
hinged to the tricycle frame at the joint A.
Figure 2. is a view of a rear-driving safety bicycle.
Figure 3. denotes the figures 1 and 4, connected together at the joint A, to
figure 4 on the frame E to form a tandem cycle or velocipede.
Figure 4. represents a view of figure 5 converted into a tricycle, by attaching the
front fork C to the joint B.
Figure 5. is a view of the rear portion of figure 4 disconnected from the front
fork C.
The object of my invention is to convért a tandem cycle figure 3, into either a
"Cripper" type tricycle as figure 4, or into a rear driving safety bicycle as
figure 2. (and it consists in attaching the upright stem J at the joint A, to the
frame E of the tricycle, an upright in the rear to carry the seat G, with the front
fork of figure 2 to form the aforesaid parts of the tandem cycle,) by disconnecting
the various portion of figures 3, to create either figures or 4.
The tandem cycle consists in attaching to the frame E of an ordinary tricycle of
the "Cripper" type, an upright stem in the rear of the stem carrying the seat G.
This upright stem is attached to the frame E of the tricycle by a transverse joint A
on the bar J. The upright stem J carries lugs to form centres by which a frame I
carrying a rear driving wheel, similar to the rear frame of a rear-driving safety
bicycle, (figure 1) is attached in the rear of the tricycle, thus making a tandem
velocipede with four wheels, (figure 3.) the front one of which is the steering
wheel C, and the other three are driving wheels, the front pair being driven
indirectly through a pedal crank axle K by the front rider, and the rear wheel
through a pedal crank axle L by the rear rider.
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
The combination of a tandem cycle or velocipede capable of being converted into
either a "
Cripper" type tricycle, or into a rear-driving safety bicycle, substantially
as herein described and according to the accompanying drawings.
Dated this 26th day of November 1889.
WILLIAM PATMORE,
Applicant.
