PROVISIONAL SPECIFICATION.
An Improved Oyole that may be Employed either as a Trioyole or
as a Bicycle.
1, WILLIAM HERBERT DAWSON, of 87 Mouton Road, Eccles, in the County
of Lancaster, Manager, do hereby declare the nature of this invention to be as
follows:-
This invention relates to cycles. The objects of this invention are to obtain a
machine that will combine the tractional advantages of a bicycle, with the
accommodation for carrying more than one person that is obtained in a tricycle,
and ready means for the conversion of a machine constructed according to this
invention to be used either as a bicycle for the conveyance of one or two persons,
or as a tricycle for the conveyance of persons sitting side by side.
I attain the objects set forth by the meaus hereinafter described reference being
made to the accompanying drawing representing an outline plan view of a machine
constructed according to this invention.
I employ duplicates of all parts 6 the framing o and the wheels d of an ordinary
safety bicycle, except the front wheel j and the steering fork f; each set of said
parts, frame, and wheel are constructed as for a bicycle, and are connected by
being placed near to and parallel with each other, the handle bars fitted into the
steering fork sockets of said frames and attached to a horizontal transverse bar in
which teeth are formed for a pinion to work therein, or to parallel bars as u or
other equivalent. I connect the rear portion of the machine either by means of a
distance rod or tube as g with ball or other suitable joints at g' and g³ or other
equivalent bars or stays to keep the rear wheels parallel, or said distance bars may
be attached to and connect the seat brackets.
I form a steering fork socket in the centre of the aforesaid parallel or other
bars u in which an ordinary steering fork is fitted with the front wheel of the usual
bicycle pattern. The bare u and g may be tolescopic.
By these means a tricycle is constructed with uniform action of the steering
apparatus from separate handle bars, and said tricycle may be readily converted
into an ordinary safety bicycle by dispensing with the parts y and u and duplicate
portions of the machine, and attaching the steering fork with the wheelj to one
of the frames c in the usual manner.

COMPLETE SPECIFICATION.
An Improved Cycle that may be Employed either as a Tricycle or
as a Bioyole.
I WILLIAM HEBBERT DAWSON of 87 Moulton Road, Eccles, in the County
of Lancaster, Manager 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 relates to oycles. The objects of this invention are to obtain a

page_text: machine that will combine the tractional advantages of a bicycle, with the
accommodation for conveniently carrying more than one person that is obtainable
in a tricycle, and ready means for the conversion of a machine that is constructed
according to this invention so as to be used either as a bicycle for the conveyance
of one or two persons in either single or tandem machines or as a tricycle for the
conveyance of persons sitting side by side in pairs.
I attain the objects herein set forth by the means I will now describe and as
shown in the accompanying two sheets of drawings in which
Fig. 1. represents the frame, driving wheel, gear wheel, chain, pedala, seat
pillar, and seat of a safety bicycle of the ordinary construction for either a lady or
a gentleman. Fig. 2 is a plan of the same.
Fig. 3 is a side view of an ordinary steering fork with leading wheel appertaining
to a like machine.
Fig. 4 is a side view, Fig. 5 a plan and Fig. 6. a front view of a tricyclo
converted from two ordinary safety bicycles as represented on Sheet 1. without
alteration of parts.
Figs. 7 to 10 are details, drawn to an enlarged scale, of additions required in
order to construct a tricycle according to my invention as shown on Sheet 2. from
two ordinary safety bicycles, or tandem safety bicycles.
In the several views shown similar letters rofor to similar parts.
In order to construct a tricycle according to this invention for the conveyance
of two persons from a pair of ordinary safety bicycles, I disconnect the front wheel
and steering fork shown in Fig. 3, from the rear portion of the machine shown in
Fig. 1. and place two of such rear portions consisting of the parts 6 the frame o and
the wheel'd in a parallel position.
b
I connect the rear portions of the frames c by means of a tube or rod g one end of
said rod being formed with a right and the other end with a left hand screw thread to
screw on or into correspondingly screwed studs fitted to the frames cat g' or g' or
in lieu of said studs, eye bolts g may be fitted to the frame c in like positions and
the ends of the connecting rod g formed with studs g to fit therein as shown in
Fig. 10. A diagonal stay is secured to the back fork of each of the frames e by
a detachable clip as 9 6. I connect the front portions of the frames a by means of
a bracing as shown in Fig. 9 with a socket m in which I place the upper
portion of the steering fork said socket being confined between self contained
ball bearings as m'. The terminals g and g' of the aforesaid bracing are formed
to fit on the parts and of the frames o and are connected therewith by passing
a tubular bolt as n Fig. 7 through said terminals and the front end of the frame c
the part o' of each frame resting on ball bearings t that are attached by means of
the nuts or equivalent to the lower end of the bolt n.
The terminals q' rest on the ends of the frames o and are each surmounted by a
toothed wheel ae u or an equivalent which rests on self contained ball bearings placed
between said terminals and the hubs of the wheels u.
The handle bars of each of the bicycles which are utilized for the construction
of a tricycle therefrom, are inserted in the ordinary manner in the front of each of
the frames c and the aforesaid tubular bolts n, and said handles n' are united by
the ordinary form of clip n. I place an intermediate tooth wheel u¹ on the upper
end of the steering fork and connect the aforesaid wheels by means of an
endless chain as u whose end portions have clip supports u attached to the
wheels u.
The wheels u are each secured to the handle bars n' and the wheel u'
to the steering fork in such a manner that they will easily slide therefrom when
required to be disconnected, but will not turn independently of the handle bars or
steering fork.
By these means a tricycle is constructed from two ordinary bicycles without
alteration in any of the parts of said bicycles and may be reconverted into two
bicycles by discarding the added parts herein before described and replacing the
front wheel steering fork and handle bar in each machine.
Tandem bicycles may be connected and disconnected in like manner.

page_text: Having now particularly described and ascertained the nature of this my said.
invention and in what manner the same is to be performed I declare that what.
I claim is :-
1st. The construction of a tricycle from two ordinary safety bicycles both of
which may be of the same pattern, or one a lady's machine and one a gentleman's.
machine in the manner substantially as herein before described.
2nd. In tricycles that are constructed from two ordinary safety bicycles the
combination therewith of the added parts eubstantially as represented by Figs. 7
to 10. on Sheet 2 of the accompanying drawings and as herein before described.
