An Improved Safety Lock.
I, FELIX SCHNEIDER of Waisenhausstrasse, Dresden, in the Kingdom of Saxony,
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 following statement :-
The safety lock of this invention is designed mainly for application to the closing
bars of travelling baskets or to bolts carried in staples.
In the drawing
Figs 1, 2, 3, 4, are views of the lock in longitudinal and cross section. Fig. 5 a
front view of the same and Fig. 6 shews the key.
The lock consists mainly of a cylindrical sleeve h; a spring tongue z springing
out of the same and acting as a bolt or catch; a ball shaped or cylindrical ring r
to be slid on to the sleeve h and having an annular recess a within its central bore
so that when slid on to sleeve hit may be secured thereon by spring z springing
into recess a (Fig. 2). One end of the bore of ring r is somewhat smaller than the
other end so that may only be slid upon sleeve h from one end. The tongue or
catch z is released from recess a by means of the key s which presses down an angle
piece k, w arranged in connection with tongue z and thus accomplishes its release.
In order that the angle piece k, w may be pressed down without binding or clogging,
it is at the arm w, somewhat chamfered off on one side so that the key ward c may
easily slide on it and press it back (Figs. 1, 3).
For the purpose of preventing the opening of the lock by improper keys or other
tools there is in addition to the stem or pin n of the lock projecting through a
slot hole i of the one arm k of angle plate w, k, also a projection e on the inner
wall of sleeve h, and there are also provided respectively on the oue hand on angle
plate arm k and on the other hand on plate t curved projections v, x, corresponding
to which the key & is provided with wards so that it may turn unimpeded against
angle plate arm w which with any other key or tool would be prevented by
projection e and curved projections v, x.
The lock is adapted for use by mounting the sleeve on a closing bar or bolt
provided at one end with a fixed knob or projection and after the bar or bolt has
been passed through the corresponding eyes or staples, ring r is placed thereon
to prevent an unwarranted unfastening of the bolt. The sleeve h may however
also be fixed direct to boxes and other receptacles, the cover or lid then being
provided with a corresponding aperture for it to pass through and the ring to be
placed on it.
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 safety lock for use in connection with closing bars, bolts and the like for
travelling baskets, boxes and other receptacles consisting of a sleeve h, a spring
tongue or catch 2, a ring r for sliding on to said sleeve and provided with a recess a
in which tongue z is adapted to engage for the purpose of securing the ring on the
sleeve, and of an angle piece w, k, in close connection with tongue z by the
pressing down of which angle piece by means of a key the tongue z is released

described and shewn.
