Improvements in and relating to Velocipedes.
1 ASSER JACOB SAMUELS of 556 Heerengracht Amsterdam, Holland, Cycle Manu-
facturer, do hereby declare the nature of this invention and in what manner the
same is to be performed to he particularly described and ascertained in and by the
following statement:-
My invention relates to improvements in velocipedes having single driving or
steering wheels; and the object of my invention is the reduction of vibration.
attain this object by the mechanism illustrated in the accompanying drawing
in which Figure 1 is a view in side elevation of the driving wheel of a rear-driving
bicycle or tricycle showing my improved method of mounting the said wheel, and
Figure 2 is a view in side elevation-on an enlarged scale--of the mechanism
constituting my invention.
Similar letters refer to like parts throughout the several views.
The axle a is carried
The wheel A is mounted on an axle a in the usual manner.
by two bars B having enlargements & formed in them. The enlargements are
provided with slots to receive the axle a which is locked to the said enlargements
of the bars B by the nuts a'. Each of the bars B is mounted in two sockets (
and formed on, or carried by, a frame C. The bars B are adapted to slide freely
in the sockets (and C2, and their movements are controlled by springs D and DI
encircling the bars B, the former acting between the top of the enlargements band
the bottoms of the sockets (and the latter acting between the bottoms of the
sockets and suitable check nuts E, E threaded on the lower ends of the bars B.
The sockets and C2 may be of the type illustrated, or of any other suitable type,
adapting at least one of them to be circumferentially adjustable and easily detached
from the frame C. The frames C are provided with suitable lugs, or their equivalents,

diamond" fraine. For a cross frame
part of the frame illustrated represents a
only one lug would be required on each of the frames C as shown by Figure 2.
The frame C is fixed at such an angle with the horizontal frame as will place it at
about right angle with a line drawn between the centres of the axles of the driving
wheel and pedal cranks. By this means the tension of the driving chain will not
be materially varied by the movement of the axle of the driving wheel with respect
to the frame carring it. When this device is applied to the steering wheel of a
cycle the frames are fixed to the ends of the prongs of the fork adapted to carry
the said wheel, a suitable lug being formed on each of the frames as shown by
fine dotted lines in Figure 2 to receive the end of one of the prongs of the said
fork.

It will be understood that when a wheel mounted in the manner hereinbefore set
forth meets an obstacle on the road it rises against the spring D & D' independent
of the frame carrying it.
I am aware that prior to the date of my invention, the wheels of cycles have
been elastically mounted, in the frames carrying them, and I therefore do not
broadly clain such, but having now particularly discribed and ascertained the nature
of my invention, and in what manner the same is to be performed, I declare
what I clain is :-
1st. Mounting the single driving or steering wheel of a cycle in the manner, and
for the purpose, specifically as set forth.
2nd. In a cycle, mounting the driving or steering wheel on an axle carried by
two bars having slotted enlargements to receive the said axle and adapted to slide

of the cycle, and be controlled by springs arranged and acting in pairs, as set
forth.
3rd. In a cycle, mounting the axle carrying the driving wheel on bars adapted to
slide in sockets carried by frames fixed to the main frame of the cycle at such an
angle with the horizontal plane as will place the axes of the said bars at right angles,
or approximately so, to a line drawn between the centres of the axles of the driving
wheel and pedal cranks, as and for the purpose set forth.
4th. In a cycle, the combination with the fork or frame adapted to receive the
driving or steering wheel, of the bars B having enlargements to receive the axle a
of the said wheel, the sockets C and C2 carried by the frames C and adapted to receive
the sliding bars B, and the springs D and D₁ encircling the bars B and elastically
controlling their movements, all combined, arranged and operating, as and for the
purpose set forth.
