Improvements in and relating to Convertible or Sociable Bicycles and
Velocipedes.
JOHN AYLWARD, Leicester Street, Coventry, Manufacturer, ARTHUR ERNEST
COMLEY, "Glenthorn," Elly's Road, Coventry, Manufacturer, do hereby declare
the nature of this invention to be as follows:-
We convert a single bicycle or velocepede into a sociable, carrying two persons,
one on each side of machine, by means of a detachable cross bar carrying two
saddles as hereunder described.
A bicycle or velocipede, constructed according to this invention, is made with
detachable portions, namely, a crossbar carrying two saddles, one on each outward
portion of the said crossbar, the saddles being held in a rigid position by lug or
clip split or otherwise. From the said crossbar a connecting bar or pillar extends
downwards to the centre pin of back wheel, or to the back portion of the frame
and is fixed by a stud, clip, or socket.
The centre portion of the said crossbar extends downwards when desired and
may fit in, or on, the down pole or pillar or other portions of the frame.
The action of the motive power is gained by extra long cranks which are about
double the length of the ordinary crank.
The largest end of the said long crank, is key'd or fixed, by cotter or other
arrangement to the outward end of the pedal pin of the short crank.
The said pedal pin is made of extra strength to carry the said long ciank.
The said long cranks may be removed by dislocating the said cotters.
The said sociable or duplicate machine may be converted to a single machine by
removing the two said cotters of the said long cranks and the two said studs from
the said connecting bars or down pillars, or by lifting the said connecting bars or
down pillars from the said clips or sockets and placing one of the said saddles
with its saddle pin, in the down pole or centre pillar of the frame.

Improvements in and relating to Convertible or Sociable Bicycles and
Velocipedes.
We, JOHN AYLWARD, of Leicester Street, Coventry, Manufacturer, and ARTHUR
ERNEST COMLEY, "Glenthorn," Ellys Road, Coventry, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to velocepedes and consists principally of 2 parts, one a
novel construction of detachable saddles and their supports. And the other a
novel construction of cranks for gaining motive power.
In order that the invention may be properly understood and readily carried into
effect, we will proceed to describe with the aid of the accompanying drawings, the
best methods known to us at the time of filing this our Complete Specification.
Figure I, shows a crossbar Id, carrying 2 saddles which fits in socket, I", and the
connecting bars or pillars, 1b, which fit in sockets, I".
Figure shows the elevation of one of the said long and short cranks, which
may be connected by cotter or other arrangements at 2", 2, 29.
Figure 3 shows elevation of short and long cranks stamped or forged in one piece
fixed to the bracket spindle at 3".
Figure 4 shows elevation of duplicate long and short cranks and chain wheel
when finished, without any cotter arrangement, which may be welded, (after being
worked) in the centre of that portion which is between the two short cranks and
forms the spindle which revolves in the base bracket, the said base bracket may
be sectional when desired. The centre portion may also be dovetailed and fixed by
gland or sleeve arrangement 4". This elevation being without cotter arrangement
is more applicable to unconvertible sociable bicycles.
Figure 5, shows base bracket spindle, grooved or flattened on both sides at one
end, so that the two inside cranks may fall either together or alternately.
Figure 6 shows another method which produces the same result as Figure 5, by
this arrangement only one groove or flat at each end of bracket spindle, is required,
the right hand crank having two holes for cotter-pin if required.
Figure 7 shows front elevation of sociable bicycle, showing clearance on either
side, back and front.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
I. The simplicity of disconnecting the saddles and their supports by lifting the
crossbar, Id, and its supports, Ib, from their sockets, 1", 1º, leaving socket 1ª, free
to receive saddle pin for single bicycle, substantially as and for the purposes set
forth and shown.
2. The simplicity of motive power shown in Figures 2, 3, 4 and 7, substantially
os and for the purposes set forth and shown.
3. The clearance shown in Figure 7, having no parts at back, outside or front
which will in any way impede or obstruct the rider or riders when mounting or
dismounting.
4. That our arrangements as shown in Figures 2, 3, and 4, may be used for or
applied to, unconvertible duplicate bicycles or veloce pedes, without any alteration
of our simple, novel, arrangement for gaining motive power.
Dated this 21st day of March 1899.
