Improvements in and connected with the Handle Bars of Bicycles.
I, CARL HOFMANN, of 66, Klosterstrasse, Breslau, in the German Empire, 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 follow-
ing statement:—
This invention relates to a spring arrangement in the handle bars of bicycles
and will be hereinafter described with reference to the accompanying drawings in
which:-
Figure 1 shews a partial vertical section and side view without the brake
accessories.
Figure 2 represents a front view of the handle bars and brake; and
Figure 3 a side view with the brake.
The handle bar pillar a is, at some distance from its upper end, provided with
the diaphragm or transverse wall b so that thereby a cylinder a is formed in which
a piston c, resting upon the spiral spring d, can slide. A piston rod f is attached
to the piston and passes through a stuffing box e. It is advantageous to fill the
cylinder a, upon both sides of the piston, with oil, glycerine or other suitable
liquid and to provide perforations in the piston which allow the liquid to pass
from one side to the other. This arrangement considerably reduces shocks and
vibrations. The handle bars g are fixed upon the upper end of the piston rod f,
and connected with them there is a tube which passes over the nuts and k of
the cylinder in such a manner that the cylinder a and consequently the pillar
is compelled to take part in the horizontal movements of the handle bars while
these latter are at the same time free to move up and down. This is accomplished
by forming the upper nut hexagonal or non-circular, the tube h being formed to
correspond. The nut is circular. The tube is consequently free to move up and
down but any horizontal movenient communicated to it is imparted to the pillar a.
In practice it is lyantageous to permanently connect the handle bars and the

2. In connection with the handle bars of a bicycle a cylinder a in the handle
bar pillar, a piston resting upon a spring in the cylinder, a piston rod connected
with the piston and having the handle bars attached thereto, a tubular part or
sleeve h, and a disc n having a curved slot o in which the bearing p of the brake
lever can move, substantially as and for the purpose hereinbefore described and
as illustrated by the accompanying drawings.
