COMPLETE SPECIFICATION.
Improvements in Velocipedes.
1, FRANZ XAVER BARTL, of the Roman Catholic Presbytery at Nagy
Becskerek, in the Kingdom of Hungary Comitat Torontal, 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 an improved form of tricycle the essential features of
which are illustrated by the accompanying drawings in which :-
Figure 1 is a view in side elevation of the tricycle, and
Figure 2 is a view in rear elevation thereof.
--
Throughout both views similar parts are marked with like letters of reference.
My improved tricycle has two driving wheels a, a, and a front steering wheel n.
The rims a¹ of the wheel a carry any suitable form of tyre and are connected with
the hub c by means of spokes in the well-known manner.
In addition to the
spokes b, each of the wheels is also, provided on one side with spokes d which carry
a ring e concentric with the wheel. The wheels a, a, are placed opposite to each
other with the rings e, e, on their inner sides and they are maintained at the exact
distance apart by means of a polygonal frame consisting of longitudinal stays f, f¹,
and transverse stays g. At the place indicated by arrows in Figure 2, a portion of
the ring e is broken to show clearly the connection of the longitudinal stays f with
the transverse stays g.
The polygonal frame is connected with the rings e by means of rollers / carried
by the said frame and of a suitable section to engage with the rings e, so that the
wheels a, a, are maintained at a given distance apart, and are free to rotate
independently of each other.
This construction is a substitute for the cross axle which has hitherto been
employed to connect together the parallel wheels in tricycles.
On the three lower transverse stays g which are preferably made of steel tubing
is mounted a polygonal frame composed of members i to carry the saddle pillar o
carrying the saddle p and the steering bead or socket k which may be of the known
construction to receive the steering pillar carried by the fork m carrying the
steering wheel n, and itself carrying the transverse handle bar l.
The pedal crank axle q is mounted in bearings carried by the two lower
longitudinal stays f¹ and by the central hollow stay o' in which the saddle pillar o
is adjustably mounted. The crank axle q is provided with pedals r and it has on
its ends chain wheels s, s, which are geared with chain wheels u, u, on the driving
wheels a, a, by means of chains t, t in the well-known manner.
The peculiar construction of the framing which connects the two wheels a, a,
gives rigidity to the whole machine, and allows of the convenient stowage of
luggage, and if required of mounting a motor for propelling the tricycle.
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 :-
(1.) The improved construction of tricycle substantially as herein before described
and illustrated by the accompanying drawing.
(2.) A tricycle characterized by two driving wheels having at their inner sides
concentric rings which support a frame carrying the seat and propelling gear for

page_text: the rider, the driving wheels being free to rotate in the said frame while they are
held at a given distance apart without the use of a common axle, as set forth.
Dated this 22nd day of November 1894.
