COMPLETE SPECIFICATION.
An Improved Steering Lock for Velocipedes.
I, ALBERT SCHAFER, of No. 4, Ludwigstrasse, Geestemunde, in the Empire of
Germany, Machine Inspector, 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 subject of the present application is a locking device for preventing move-
ment of the steering post carrying the front wheel of velocipedes, and consequently
rendering all attempts to ride or wheel away the machine, when, in the locked
condition, impossible.
The accompanying drawing shows a bicycle steering head with the subject of
the present invention represented in section.
The steering fork B, carrying the front wheel, is connected to the steering
post or steering tube C, which is inserted in the steering head D, and carries at
its upper end the handle bars. At a convenient point upon the steering head,
and at right angles thereto, is applied a small socket E, screw-threaded internally
at the part next the steering head. In this threaded portion works a screw H,
having a square or other polyangular head G and a collar F. The end of this
screw has a reduced portion J, which, when the screw H is fully screwed up,
projects and bears against the steering post, or it may enter a suitable opening
made therein. By means of the screw S inserted in the unthreaded portion of
the socket E, the screw H is prevented from working loose and getting lost by the
vibration set up while riding, the portion of the screw S which projects into
the socket E coming in contact with the collar F of the screw H, which collar in
the drawing is shown as abutting against the threaded portion of the socket.
The head G of the set screw is enclosed in the socket, and cannot be operated
from outside, except by means of a specially formed key, which the rider carries
in his pocket.
When it is desired to lock the velocipede and protect it against unauthorized
riding, the wheel is set preferably at an angle to the length or direction of motion
of the vehicle, and the screw H is screwed home, whereby the steering post Cin
the head I will be held immovable, and the velocipede can only be driven round
and round in a circle. The end of the key and the head G of the screw may be of
various angular forms, in order to avoid a too frequent similarity of keys.
Having 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
I claim is
1. A safety locking device for velocipedes, consisting of a screw H, or the
like, working in a socket E on the steering head D, having a point J entering the
steering post C, for the purpose of locking fast the post and wheel carried thereby
at a suitable angle to the length of the vehicle, and thereby preventing un-
authorized riding of the machine.
2. A safety locking device for velocipedes according to Claim 1, consisting of

page_text: a screw H working in and enclosed in a socket E, said screw being provided with
a head G of suitable angular form, and having a collar F, said collar, in the
event of the screw H working loose, coming in contact with a screw S in the
socket E projecting into the interior of the socket, and thus preventing the set
screw H from being lost.
