PROVISIONAL SPECIFICATION.
Improvements in and relating to Four-wheeled Cycles.
I, GUSTAV SPENLEIN, of 18, Kaiser Wilhelm Ring, Mainz, in the Empire of
Germany, Merchant, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved four-wheeled cycle arranged to be moved
by four persons sitting two and two side by side and facing one another.
This improved quadricycle consists substantially of two side frames built like
bicycle frames placed side by side and rigidly connected with each other by
cross bars or the like in front and behind, so that they form a perfectly rigid
vehicle with two front and two back wheels. In its longitudinal direction this
vehicle is provided with two auxiliary frames arranged parallel to the side frames.
Upon the upper cross bar in front two saddles are mounted for the front riders,
and upon the upper cross har at the rear two saddles are fixed for the back
riders, these four riders, as before stated, sitting two and two side by side and
facing one another, so that the front riders turn their backs in the direction of the
run of the machine. Each rider of the vehicle actuates a crank shaft held by a
bracket in the auxiliary frame and transmitting its motion by means of chains
or the like to two shafis furnished with two toothed wheels engaging with each
other; from the back shaft the motion is communicated to the back wheels.
For steering purposes the vehicle is provided with a simple device; the fork
tubes of the front wheels are fitted with short levers connected by a rod which
may be actuated through the intervention of a gearing connected with a steering
rod mounted in the middle of the frame and turning in bearings of the same, such
steering rod carrying a steering wheel under the control of the riders seated at
the rear.

Improvements in and relating to Four-wheeled Cycles.
I, GUSTAV SPENLEIN, of 18, Kaiser Wilhelm Ring, Mainz, in the Empire of
Germany Merchant 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:-
-
My invention relates to eyeles, and comprises an improved four-wheeled cycle
arranged to be moved by four persons sitting in couples side by side, those in the
front facing those in the rear.
In the accompanying drawing my improved cycle is represented.

page_text: Figure 2 a plan, and
Figure a front view of the same.
Figure shows a view of the steering gear drawn to a larger scale.
This improved quadricycle consists substantially of two side frames a built like
bicycle frames placed side by side and rigidly connected with each other at
their fronts by cross rods band at their backs by rods e so that a perfectly
rigid vehicle is formed, which has two front steering wheels and two back
driving wheels e. In its longitudinal direction this vehicle is provided with two
auxiliary frames arranged parallel to the side frames.
Upon the upper front cross bar or rod band in alignment with the auxiliary
frames are mounted two saddles g for the front riders, and upon the upper cross
bar or rode two more saddles are mounted for the rear riders, the riders sitting
two by two and side by side facing one another, as before stated, so that the front
riders have their backs in the direction the machine is running. Each rider of
the vehicle actuates a crank shaft i held by brackets in the auxiliary frames f.
These crank shafts are provided with chain pinions k which transmit the motion
by means of chains to two shafts m m' furnished with two toothed wheels m¹
engaging with each other. Near each of its ends the back shaft m¹ is furnished
with chain pinions which communicate the motion by means of chains p to
pinions fixed to a spindle forming the axle of the rear driving wheels e, this
spindle being carried in the back cross rod c¹ to which the rear ends of the
auxiliary frames f are secured.
For steering purposes the fork heads of the front wheels are fitted with
short levers connected together by a rod t which is actuated by a short rod u
fixed to the boss of a bevel pinion and carried by a standard attached to the
lower front cross bar b', the said pinion gearing with another pinion secured
to one end of a horizontal shaft to which is fixed a steering wheel y.
For enabling the riders to better mount the vehicle two steps are provided on
the outside of the side frames a.
it
ifaving now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
T claim is:--
1. In a four-wheeled cycle the combination of two side frames a built like
bicycle frames and connected rigidly together by means of front cross rods b b
and back cross rods e c', with two auxiliary frames of carrying four saddles
and four crank shaft brackets j, as and for the purpose set forth.
2. In a four-wheeled cycle the combination of the fork heads r, with short
levers and a rod t, being actuated by the steering mechanism, as and for the
purpose set forth.
3. In a four-wheeled cycle the combination of the rod with the rod u fixed
to the boss of a bevel pinion r gearing with another pinion wel which is carried
by a shaft furnished with a steering wheel y, as set forth.
4. In a four-wheeled cycle the combination of the two side frames a rigidly
connected with each other by cross rods b, b¹ c, c¹ with two shafts m m¹ furnished
with toothed wheels n n¹ gearing with each other and being operated by means
of crank shafts and chains, as and for the purpose set forth.

5. In a four-wheeled cycle the combination of two auxiliary frames f with
saddles mounted on the cross bars band at the ends of the auxiliary frames in
such manner that the riders sit in couples and face each other, as and for the
purpose set forth.
