Improvements in Bicycles, Tricycles, or Tandems by Making them
Convertible to the Use of One or More Riders.
JAMES PARR Cycle Manufacturer 61 Friar Lane Leicester 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 has for its object improvements in cycles, and relates to means
whereby a safety bicycle or tricycle may be rendered capable of being used either
for one, or more riders.
The method of carrying my invention into effect is as follows: riz.—
The part known as the socket in which the steering pillar turns, and which
carries the steering pillar, handle bar, forks and front wheel-I make detatchable ;
and this detatchable part is usually removed, before disconnecting that portion
of the machine which carries the pedals, handles, seats and saddles. When this
last nained portion, carrying the pedals, handles, seats & saddles, is taken away,
and the aforementioned detatchable socket, A. Fig. 1 Sheet 1 carrying the steering
pillar, handle, forks and front wheel, is connected to the remaining part of frame
of cycle, the tandem tricycle, bicycle or triplet is thereby couverted into a single
tricycle or bicycle.
In the accompanying sheets of drawings annexed to this Specification
Fig. 1 shows a side elevation of tandem complete with detatchable socket A,
held in position by hinged clips B. B.

page_text: Fig. 2. shows side elevation of front and middle part of tandem safety bicycle
with wheel, fork, handle bar, steering pillar, and detatchable socket in frame and
held in position by hinged clips B. B.
Fig. 3 shows middle part of tandem with detatchable socket removed from
clips B. B and back frame removed.
Fig. 4. shows side elevation of front wheel, with handle bar, steering pillar,
fork and detatchable socket A taken away from tandem part and ready to be put
in position in back part to form a single machine.
Fig. 5. shows side elevation of back part of cycle as a single machine ready for
attatching detatchable socket A by clips B. B.
Fig. 6 shows side elevation of complete single machine with detatchable socket A
fixed in frame and held in position by clips B. B.
Fig. 7 shows side elevation of back and middle part of machine as a tandem
with front wheel, handle bar, steering pillar and detatchable socket removed from
clips B. B.
In the accompanying sheets of drawings the detatchable steering socket A is
held in position by two clips B. B having one side hinged and the other side
fastened by screws or bolts. Instead of being hinged both sides may be made
with lugs and held in place by screws, bolts and nuts or similar devices. Or the
detatchable steering socket A may be made with projecting lugs and secured to
other portion of frame by a screw and nut, screws and nuts, bolt or bolts, or by a
cotter pin passing through portion of frame and projecting lug, and held by nut
or screw. Or the detatchable socket A, may be held by a band clip or clips.
I wish it to be particularly understood that I do not limit myself to the precise
details of the method of fastening or attatching detatchable socket herein before
described but that I hold myself at liberty to make such changes and alterations
as fairly fall within the spirit and scope of my invention.
Having now described the nature of my said invention and the manner of
carrying the same into effect I wish it to be understood that what I claim is
A detatchable steering socket as hereinbefore described and by which a single
bicycle or tricycle can be converted to carry one or more riders.
Dated this 5th day of September 1895.
