PROVISIONAL SPECIFICATION.
A Compound Bicycle and Tricycle, and Means of Connecting same..
I, JOHN WILLIAM BROWN, of Boothbank, Boothtown, Halifax, in the County
of York, Mechanic, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to combine a tricycle and bicycle into one machine,.
so that they may be made to carry two or three persons at the same time. In
carrying out my invention, I remove from the tricycle the ordinary front wheel and
fork, and by means of a connecting link and swivel joint I connect such tricycle to.
the back wheel of a bicycle, the swivel of the joint allowing the bicycle to move in
any direction. In connection with the tricycle there may be an additional saddle,.
crank, and chain motion, made adaptable for a third person.
This compound machine will be found useful by assisting up an inclined road a
lady who may be riding on a bicycle. The attaching and detaching of the two
machines can be quickly performed, and other advantages over separate machines.
will be found in its use.

COMPLETE SPECIFICATION.
A Compound Bicycle and Tricycle, and Means of Connecting same..
I, JOHN WILLIAM BROWN, of Boothbank, Boothtown, Halifax, in the County
of York, Mechanic, 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:-
The object of my invention is to combine a bicycle and tricycle together, or to
have a tandem attachment to a bicycle, so that they may be made to carry two
persons at the same time. In carrying out my invention, I remove from a tricycle
the ordinary front wheel and fork, and by means of a connecting link and swivel
joint I connect such tricycle to the back fork or wheel of a bicycle, the swivel of
the joint allowing the bicycle to move in any direction. In connection with the
tricycle there may be an additional saddle, crank, and chain motion, made adaptable
for a third person.
In order that the nature and object of my said invention may be more fully
understood, I will now proceed to describe the same with reference to the accom-
panying sheet of drawings illustrative thereof, wherein A of Fig. 1 is elevation of
an ordinary bicycle having my improved tandem attachment B connected to it,
and Fig. 2 is plan view of the same. The tandem attachment B is practically
a tricycle with the front wheel removed, and the front fork D of the said
tricycle is connected to the back fork C of the bicycle by the joint E as shewn
in the drawings. Many methods may be employed for connecting the two
machines together, one of which is shewn in enlarged elevation Fig. 3 and plan
view Fig. 4, and another in elevation Fig. 5, in all of which views C represents
the back fork of the bicycle, D the front of the modified tricycle or tandem attach-
ment, and E the joint, consisting in Figs. 3 and 4 of curved portion E on
both arms of which are screw threads, by which the said curved portion is
secured to the front fork D of the tricycle or tandem attachment on the one

page_text: hand, and to an extension of the back fork C of the ordinary bicycle A on the
other hand.
In Fig. 5 I have shewn a slightly different construction of the connecting
parts, in which the part E is secured to the end of the fork D by a knuckle
joint instead of being screwed into the end of the said fork as above described;
or a ball and socket joint may be used for coupling the two together. What-
ever form of joint is adopted, it must be of such a character as to enable the
bicycle to occupy all possible positions, and even to fall over onto either side
without becoming disconnected from the tandem attachment, or without even
affecting its horizontal position. This combined machine will be found useful in
assisting up an inclined road a lady or other person who may be riding on the
tricycle. The attaching and detaching of the two machines can be quickly
performed, and other advantages over separate machines will be found in its use.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The connecting together of a bicycle and tricycle in the manner and by the
means substantially as shewn and described herein.
