Improvements in the Construction of Velocipedes.
I, STANISLAU ZUNGL, of No. 3 Hulkova Prague, Austria, Architect, do hereby
leclare 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 relates to a velocipede which can be driven by the hands as well
as by the feet of the rider. In consequence of the peculiar construction of the
frane and of the connection of the crank and pedal with a suitable connecting or
guide rod, the machine can be much more readily and conveniently driven up hill
than heretofore.
In the accompanying drawings,
Figure 1 is a side view and Figure 2 a plan of a bicycle constructed according
to my invention.
Figures 3 and 4 are a side and front view respectively of the gear for driving the
machine by hand together with the connecting or guide rod.
Figures 5 and 6 are a front and a side view respectively of the driving rod and
wheel.
Figures 7 and 8 are a side and a front view respectively of the guide rod
joint.
Figures 9 and 10 are a side and a front view respectively of the rear fork and
wheel.
Figures 11 and 12 are a side and a front view respectively of the driving
gear.
Figure 13 is another side view of the rear fork and wheel.
Figure 14 is a longitudinal section of the air pump.
Figures 15 and 16 show the rear wheel and fork in front view.
:
Figures 17 and 18 show in side view the connection of the rear wheel and fork
with the guide rod.
Figure 19 is a longitudinal section of the guide rod.
Figures 20 and 21 show a plan of the guide rod.
Figures 22, 23 and 24 are a side, and a front view, and a plan of the said
guide rod.
The bicycle frame consists of the guide rod d, the rear wheel fork a, the saddle
bar e and the connecting rods ff and 9 g¹. The rods g g' are fixed to the saddle
bar and are provided below with the bearings t t.
This
In the bearings are mounted the gear wheels ii. The rods g g' are also
fixed to these bearings and are furnished above the hub, with the openings 9 91
wherein rests the axle of the front wheel. The rear wheel is supported by the fork
of the rod 12 which is firmly fixed to the pillar a, the latter being free to turn
within the sleeves e¹ f2. The guide rod d is moveably held in the head v of the
fork of the front wheel h and in the sleeve 13 secured to the saddle bar e.
guide-rod is furnished with transverse arms 8 8¹ (Figs 19 and 20) which are
connected by the tie rods with the upper arms 5 5 of the pillar a. The tie-
rods may be connected in parallel or crosswise. The rod d is furnished above
with a cross tube 9 upon which can turn the sleeves 16 and 17 (Fig. 2). The hand
5 forks c c are rigidly connected to the sleeves 16 and 17 which are provided with
the short arms 10 10¹.
The supports 18 which are furnished with ball and socket joints at their

page_text: extremities, are rivetted to the arms 10 10. The joint o is secured to the ball
carried by the upper end of the rod c (Fig. 7). The tie rods c c are connected at
their lower extremities to the rods 14 and 14' by the joints o' and o³, these joints
enabling the rod c to be turned in every direction, which is absolutely indispensable
to drive the machine.
The guide rods 14 and 14 are supported by the bearings m m' fixed to the
rods d d and are directly connected by means of the crossheads 19 and 19, with
the crosshead rods 15 and 151 which are carried by the tubular projections p p of
the gear wheels it. The gear wheels ii are furnished with the pedals, and
are coupled by means of teeth or of a chain with the wheels s s' mounted on the axle
of the wheel b. The rod a which is the pillar of the rear fork and is free to turn
within the sleeves e, f, contains an air pump 4 with a piston 2 and a piston rod i
provided at the top with a handle or knob z. Below, in the small tube 3 (Fig. 13)
is arranged the usual air valve 7 so that by the aid of a small indiarubber pipe
shown at 6 the inflation may be carried on in the ordinary manner by the aid of the
air pump 4.
The forks 12 and 12' are provided with the valves (Fig. 9) and oil for
lighting and lubricating purposes may be stored therein. The saddle k which is of
ordinary construction but longer than usual, is adjustably mounted by means of
suitable clips on the bar e, over the front axle in order to enable the rider to
maintain the centre of gravity in the same position relatively to the driving axle
whether travelling on horizontal or inclined ground by being able to shift his
position on said elongated saddle. The wheels ii are rotated by pedalling, and
are connected by the rods 15 15 to the guide rods 14 14' and the tie rods c c¹
(the levers bb acting also as guides or steering handles), so as to enable the gear
wheels to be driven by hand as well as by feet. As shown the guide rods are
directly connected with the rear wheel ' and hence the direction of the wheel can
be regulated by the same.
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. A bicycle or tricycle driven by the hands as well as by the feet wherein the
levers bb' loosely carried by the tubular guide rod d are directly coupled to the
crank gear wheels it so that the machine may be driven simultaneously by the hands
and feet, substantially as herein described and as illustrated in the accompanying
drawings.
2. In the velocipede above claimed a device serving as a guide in connection with
the rear wheel h', characterized by the parallel or crossed guide rods / l' and 71 73,
substantially as herein described and as illustrated in the accompanying
drawings.
3. In velocipedes the arrangement of the air pump 4 in the frame tube or pillar a
provided with the valve 3 and connected with the wheels for the purpose of
inflation substantially as herein described and as illustrated in the accompanying
drawings.
4. In the velocipede claimed in the first claim, a frame characterized by a
saddle k adjustably arranged on the bar e over the front axle in order to enable
the rider to maintain the centre of gravity in the same position relatively to the
driving axle whether travelling on horizontal or inclined ground, substantially as
herein described and as illustrated in the accompanying drawings.
