PROVISIONAL SPECIFICATION.
A Tricycle for use on Land and Water.
I, CHARLES HUELSER, of the Firm of Huelser & Co., of 142, Fleet Street, in the
City of London, Solicitors of Patents, do hereby declare the nature of this invention,
a communication to me from abroad by Georg Pinkert, of Munich, in the Kingdom
of Bavaria, Empire of Germany, Manufacturer, to be as follows:-
The object of this invention is a tricycle serving for locomotion on the water as well
as on land and essentially constructed as follows:
The two driving wheels consist of hermetically closed hollow rings provided on
their circumference with paddles. Each of these rings is secured by means of spokes
to a knave wedged on the driving axle. The latter is lodged in a frame provided in
front with an eye, in which is horizontally revolvable the vertical central pivot of a
fork to which the guide wheel is attached. The guide wheel consists of a hollow
hermetically closed lenticular body, the axle of which is revolvably lodged in the two
extremities of the fork. Each of the three wheels has attached to its circumference a
suitably projecting annular flange or tyre serving for use of the vehicle on land.
The weight bulk and equipoise of the improved vehicle are so proportioned as to
render the same light and commodious for use on land, while, when on the water, the
joint weight of rider and vehicle causes the latter to be only so far immersed as to.
admit of unimpeded locomotive operation.
Any known or suitable devices may be employed for operating the guide wheel and
revolving the driving wheels, for instance the following:
The seat or saddle is placed on the two sides or arms of the frame, which is
moreover provided with a cross piece carrying in its centre an upwardly extending
arm and below two symmetric arms. In the extremities of these two arms is lodged
the shaft to which the pedal crank and chain wheel are attached. From the latter, an
endless chain passes over another chain wheel provided on the axle of the driving
wheels. The upper arm of the cross piece referred to carries at the top a revolvable
iwo-armed horizontal lever for guiding and steering the vehicle. The extremities of
said lever are respectively connected by drawing rods with the extremities of a similar
lever secured to the top of the fork of the guiding wheel, thereby allowing the latter
to be directed by the rider.

COMPLETE SPECIFICATION,
A Tricycle for use on Land and Water.
I, CHARLES HUELSER, of the Firm of Huelser & Co., of 142, Fleet Street, in the
City of London, Solicitors of Patents, do hereby declare the nature of this invention,
a communication to ime from abroad by Georg Pinkert late of Munich in the
Kingdom of Bavaria, now of Waldheim, Saxony Empire of Germany, Manufacturer,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:
This invention has for its object to provide a vehicle adapted for locomotion both on
land and water.
Reference being had to the accompanying drawing,
Fig. 1 is a vertical longitudinal section, and
Fig. 2 a plan and partial horizontal section of the improved combined tricycle, in
which the two driving wheels A are formed as hermetically closed hollow rings, each
11-

page_text: of which is secured by means of spokes, or sheet metal cones, serving as substitutes
therefor, on a nave wedged on the driving axle i.
The frame C in which the driving shaft is lodged has at its fore extremity an
eye inwhich the upright central pivot of the fork & carrying the guide wheel B can be
turned in the horizontal or approximately horizontal sense. The guide wheel C consists
of a hollow lenticular body closed air-tight on all sides and having its axle revolvably
lodged in the two extremities of fork 6. The two driving wheels and guide wheel
have their respective circumferences determined by an indiarubber tyre. On these
tyres the vehicle runs when used as tricycle on land, while when used for locomotion
on the water; it is immersed in the manner illustrated by Fig. 1.
For steering the guide wheel B and propelling the driving wheels, A, any con-
venient devices may be employed. The driving wheels A may be constructed with
paddles but are preferably made smooth as illustrated in the drawing, when their
frictional resistance will prove sufficient for locomotion on the water. Each of these
smooth wheels is formed by a sheet metal ring d of semicircular or nearly semi-
circular circumferential cross section which is so rivetted, screwed or otherwise
secured together with two curved relatively symmetrical sheet metal rings ee, Fig. 2,
so as to leave a circular space or groove for receiving the indiarubber tyre and to
produce a hollow air-tight ring.
In order to afford additional safety on water e. to guard against accidents arising
from injury to the said hollow ring, a second air-tight hollow ring is formed internally
by the sheet metal ring, the sheet metal cones replacing the spokes, and the
have h.
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:
1.) In a tricycle for locomotion both on land and water, the combination with any
suitable appliances for operating and steering the vehicle, of two hollow hermetically
closed driving wheels, with or without paddles-each wheel having its circumference
determined by an elastic tyre, and a lenticular hermetically closed guide wheel,
likewise surrounded with an elastic tyre, substantially as set forth.
2.) In a tricycle for locomotion both on land and water, the application of driving
wheels A, each of which consists of a sheet metal ring d of semicircular or vaulted
radial section of circumference, two curved relatively symmetrical sheet metal rings e e
rivetted or otherwise connected with each other and with ring so as to form a bed
for an elastic tyre and an air-tight annular space, and two sheet metal cones, forming
with said ring d and with nave a second hermetically determined annular space,
substantially as and for the purpose set forth.
