COMPLETE SPECIFICATION.
An Improved Convertible Bicycle.
We, ALBERT THOMAS POWELL, of Claremont, Station Road, Kings Heath
Worcestershire, Cycle Manufacturer's Manager, and AIMÉ VAN DEN BOGAERDE, of
Perry Villa, Perry Barr, in the County of Stafford, Orchid Grower, 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 consists of an improved convertible bicycle in which the frame
is constructed and arranged as herein described so as to enable the bicycle to be
readily converted to suit the requirements of either a lady or a gentleman rider.
We will describe this Invention by referring to the accompanying drawing on
which Figs. 1 and are side elevations of a bicycle frame constructed according to
this Invention, Fig. 1 shewing the bicycle frame as arranged for a gentleman rider
and Fig. 2 shewing the same frame when converted for use by a lady rider; Fig. 3
is a plan of the said frame and Figs. 4 and 5 shew parts of the said frame as
hereinafter described.
In carrying out this Invention the frame is made like the usual frame of a
gentleman's bicycle but the top stay A is made detachable its front end being bolted
at al to the top lug B of the bicycle frame and the back end a² being bolted to the
seat pillar lug C. Brazed or otherwise fixed on the usual seat pillar tube D we
provide a lug E constructed to receive and be bolted to the end f¹ of the detachable
curved tube or stay F the other end f2 of which is adapted to be bolted to the ball
head lug B. Thus, in combination with the bicycle frame formed as above described,
we provide two detachable tubes namely the tube A for bolting to the ball head lug
and seat pillar C as shewn in Figs. and 3 when the bicycle is required for use by a
gentleman and the tube F which as shewn in Fig. 2 can, when the tube A is
removed, be bolted to the ball head lug B and to the lug E on the seat pillar tube D
when the machine is required for use by a lady. The ends a¹ a² of the tubes A are
by preference made forked as shewn in Figs. 3 and 4 to receive between their forked
ends the snugs b c which are formed respectively on the ball head lug B and the
seat pillar lug C and through which the fixing bolts g¹ g² respectively pass to fix the
tube A in position as shewn in Figs. 1 and 3. The ends of the tube F are by
preference similarly made of a forked form as shewn in the plan view of Fig. 5 and
the lug E is made with a projecting snug e¹ to fit between the forked end fi of the
tube F, the other end f2 of the tube F being shaped to receive the snug b¹ of the
ball head lug B and be secured by the bolts g¹ g² as above described.
It will be evident that instead of the ends of the tubes A and F being made
forked as above described, the ends of these tubes may be made solid and the snugs
of the ball head lug B seat pillar lug C and bottom lug E may be made forked to
receive the ends of the tubes and for the fixing bolts g₁ g² to pass through.
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. In a bicycle convertible for use by either a lady or a gentleman rider, making

page_text: the frame with a removable top stay A which connects the ball head lug to the seat
pillar lug and with a removable stay F to connect the ball head lug to a lug on the
seat pillar tube near the bottom bracket when the top stay A is removed, substantially
as set forth.
2. A convertible bicycle having its frame constructed and arranged with the two
removable stays A and F in the manner substantially as hereinbefore described and
illustrated by the accompanying drawing and for the purposes set forth.
