PROVISIONAL SPECIFICATION.
An Improved Spring Frame for Velocipedes.
I, JOSEF WEIKERT of Lodz in the Russian Empire, Velocipede Manufacturer
do hereby declare the nature of this invention to be as follows:-
The spring frame of this invention for velocipedes such as bicycles is composed
of steel spring rods or connections between the wheel axles and steering rod or
steering rod sleeve for which purpose the ends of said rods terminate in an eye.
A bicycle may have two spring rods on the end of the axle at each side of the
driving wheel the opposite ends of the rods taking one on to the upper part of the
steering rod or steering rod sleeve and the other on to the lower part of the same.
For the front wheel one or two rods may be employed. The rods are carried from
the wheel axles to the steering rod or steering rod sleeve in a curved form. They
are braced together to give strength and rigidity crosswise between the pairs of
rods.
The object of the invention is to provide velocipedes with a frame having such a
spring action as will prevent discomfort to the rider through unevenness in the
roads travelled over.

COMPLETE SPECIFICATION.
An Improved Spring Frame for Velocipedes.
I, JOSEF WEIKERT of Lodz in the Russian Empire, Velocipede Manufacturer
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 :-
The object of this invention is to provide velocipedes with a simple and durable
frame having such a spring action as will prevent discomfort to the rider through
unevenness in the roads travelled over. It consists of spring rods connected to the
machine without the usual bolt, screw or elastic connections.
Referring to the accompanying drawing Fig. 1 is a side view of a velocipede
with the spring frame of this invention applied thereto. Fig. 2 a part end view
and Fig. 3 a part plan of the same.
The spring frame is composed of four steel spring rods combined in two pairs,
an upper pair a and a lower pair a¹. These spring rods take each by an eye on to
the driving wheel axle and from there pass, each pair respectively, to an upper
crosshead and a lower crosshead b¹ which serve as guide bearings for the steering
rod c or for holding the steering rod sleeve d. Two similar crossheads e, e', are
fixed on the spring rods for carrying the saddle rod for saddle rod sleeve or socket g.
h are cross stays, in any suitable number, for connecting together and giving
lateral rigidity respectively to each pair of spring rods a, a'. The guide wheel
frame is similar in principle to the main frame. It consists of four steel spring
rods combined in two pairs i, ', with one or more cross stays h¹.
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:
A. frame for velocipedes consisting of steel spring rods arranged in pairs leading

page_text: from the driving wheel axle to the steering rod or steering rod sleeve and stiffened
by cross stays, without brazed, soldered, screwed, rivetted, or bolted connections
or joints, substantially as described and shewn.
Dated this 18th day of June 1891.
