Improvements in Velocipedes.
FREDRIK LJUNGSTROM, of 32 Grefgatan, Stockholm, Sweden, Mechanician,
do hereby declare the nature of this invention to be as follows:-
In that class of velocipedes wherein one rider is situated behind the other such
as in the so-called "tandem cycles" and others, the two riders are each seated
upon seats or saddles which are practically in the same horizontal line, both being
the same distance from the ground or nearly so; in such machines it has heretofore
been necessary to place the two seats a certain distance apart, so as to give
sufficient room for the movement of the knees and legs of the rear rider, or riders.
Further such an arrangement of seats or saddles necessitates the employment of a
machine of considerable length and causes the riders, by reason of their distance
apart, to present a large surface of resistance to the wind.
The object of my invention is to so arrange the seats or saddles whereby one
rider is brought closer than heretofore to the other rider, and in such a position
that the two riders will occupy less length and present less surface to the wind.
By my invention, I arrange the forward seat or saddle at a suitable height the
rear seat or saddle being arranged at a lower height relatively to the said front
saddle, the position being such that when a rider is upon the front seat or saddle,
the rear rider is brought into close proximity to the former, by reason that the
rear riders legs are beneath and move parallel or nearly so to those of the front
rider.
.
The framework of the machine between the two wheels say of a tandem bicycle,
is when arranged according to my invention considerably lessened in length and in
weight, while the rigidity is increased, and such a frame I so construct as to allow
the seats or saddles to be arranged relatively as described, and at the same time to
carry the driving mechanism such as pedals or levers in required relative positions.

I, FREDRIK LJUNGSTROM, of 32 Grefgatan, Stockholm, Sweden, Mechanician,
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 :-
In that class of velocipedes wherein one rider is situated behind the other such
as in the so-called "tandem cycles" and others, the two riders are each seated upon
seats or saddles which are practically in the same horizontal line, both being the
same distance from the ground or nearly so; in such machines it has heretofore

sufficient room for the movement of the knees and legs of the rear rider, or riders.
Further such an arrangement of seats or saddles necessitates the employment of a
machine of considerable length and causes the riders, by reason of their distance
apart, to present a large surface of resistance to the wind.
The object of my invention is to so arrange the seats or saddles whereby one
rider is brought closer than heretofore to the other rider, and in such a position
that the two riders will occupy less length and present less surface to the
wind.
In order that my invention may be readily understood I have illustrated same in
the accompanying drawings, in which
Fig. 1 shews in side elevation a tandem chain driven bicycle arranged according
to my invention.
17.
Fig. 2 is a similar view of a bicycle, but in this case the driving mechanism is
that of the treadle or lever type, and as manufactured by the New Cycle Company
Limited.
According to my invention, I arrange the forward seat or saddle A at a suitable
height, the rear seat or saddle B being arranged at a lower height relatively to the
said front saddle A, the position being such that when a rider is upon the front
seat or saddle A the rear rider is brought into close proximity to the former by
reason that the rear riders legs are beneath the body of the front rider, and move
parallel or nearly so to those of the front rider.
The framework of the machine between the two wheels say of a tandem bicycle,
is when arranged according to my invention considerably lessened in length and in
weight while the rigidity is increased, and such a frame I so construct as to allow
the seats or saddles to be arranged relatively as described, and at the same time
to carry the driving mechanism such as pedals or levers in required relative
positions.
Although I have illustrated my invention adapted to a tandem bicycle, it may be
readily arranged for triplets, quadruplets, and other velocipedes. In cases such as
quadruplets it may be desirable not to arrange the four seats or saddles so that the
front one is highest and the rear one lowest, but I may arrange, say for instance,
the front saddle at a height above the second, the third being arranged level with
the first, and the fourth below the level of the third and level with the second. In
this case the distance between the first saddle and the second, and the third and
fourth would be small, the positions of the saddles being such as I have illustrated
in the drawings, whereas the distance between the second and third would be
greater.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
Constructing and arranging the framework of velocipedes so as to receive a
saddle or seat at a suitable height and a second saddle or seat behind the former at
a lower height, and two saddles being arranged so that two riders seated thereon
are brought into close proximity one with another, substantially as and for the
purposes described and illustrated in the accompanying drawings.
