page_text: I, ROBERT BRUNO JENTZSCH, Engineer, of IV Wiedener Hauptstrasse 6, Vienna,
Austria, do hereby declare the nature of my said invention to be as follows:-
The object of my invention is to construct a simple mechanism, by which a bolt,
bar, slide or such like can be moved by the aid of a coin or its equivalent.
My improved mechanism consists, besides the aforesaid bolt, bar, slide or such like,
only of a spring actuated tumbler or lever, which is pivoted at the side of the afore-
said bolt. This bolt, slide or such like is provided with two notches into one of
which a projection of the aforesaid tumbler enters under the influence of its spring.
and prevents the bolt or such like from being operated: In this position the second
notch of the bolt or such like corresponds with a slit or notch in the tumbler. A
coin, dropped into the apparatus, will enter partly this slit in the tumbler, partly the
second notch in the bolt or such like, thus forming a sort of connection between the
two parts. The coin is prevented from dropping through by the bottom of the notch
in the bolt or such like being made somewhat slanting, so as to narrow the coin space
at the bottom. If the bolt or such like is now pushed forward, the coin, which
originally stands at or nearly at a right angle to the bolt, will be slanted and will
thereby swing the tumbler downward so that its aforesaid projection is swung out of
the first recess of the bolt or such like, so that the latter may be operated. At a
certain distance behind the second notch the bolt or such like has a third.notch or
recess, deeper than the second one.
Thus when this last recess reaches the coin, this finds room enough to drop through
and into a receptacle. This automatic releasing device may be used for many
purposes, among others, in combination with a lock for locking bicycles. In this
case a lamp hook may be attached to the side of the apparatus for placing upon it
the bicycle lamp, and the end of the aforesaid bolt or such like may be shaped so as
to pass over this lamp hook so as to secure also the lamp.

The object of this invention is the construction of a simple device for arresting
movable part of any kind, such as a bolt, slide or such like in a certain position until
a coin or its equivalent is introduced, which will liberate said part, bolt, slide, or
such like when an impulse is given to the latter in the direction in which it is
intended to be moved.
This device can be constructed for a rectilinear as well as for a curvilinear move-
ment of the part to be liberated by a coin, and is applicable for coin operated
apparatus of different kinds.
In the annexed drawing
Figure 1 shows in sectional plan view a device of this kind applied to an ordinary
bolt, in locked or arrested position.
Figure 2 shows the same view, with the bolt released by a coin and partly moved
forward.
Figure 3 shows the device in the same view, with the bolt pushed or pulled out to
'its furthest extent.
Figure 4 is a side view of the device, with the bolt in the same position as in
Figure 3.
Figure 5 shows, by way of example, in plan view a bicycle locking stand fitted with
a device of this kind.
Figure 6 is a front view of this apparatus in open position.
Figure 2ª is a cross section of the bolt after line A-B; Figure 2..
From the drawing will be seen that, besides the part to be liberated by a coin, here
by way of example the bolt a, the whole device consists essentially of but one part,
the pawl or latch b which, under the influence of a spring c of a weight or such like
is held in such position that its nose or projection 6 engages in a recess d of the
bolt a.
This pawl or latch b swings upon a pivot b' and is provided with a slot e, the
depth of which corresponds to about half the diameter of the coin to be used.
Opposite to this slot e the bolt a is provided with a recess d¹ the bottom of which
facing the slot e is inclined, as seen in Figure 2ª. This recess d¹ is so deep that the
coin f, about half of which finds room in the slot e may almost fully enter it, but not
deep enough to permit its dropping through. The recess d, into which engages the
locking or arresting nose 611 of the latch b, is so long that it permits a certain play to
the bolt. Thus when a coin f is inserted between the parts a and b, as shown in
Figure 1, the bolt a may be moved forward a little way, the latch still remaining in
its locking position, until the rounded off or inclined end of the recess d¹ strikes the
coin. The movement of the bolt being continued, the coin is forced aside, and with
it the latch b, which is thereby brought into the position shown in Figure 2, in which
the locking nose 61 is disengaged from the bolt a. The coin remains in this position
until a third recess of the bolt, situated at a suitable distance from the other
recesses, arrives opposite the coin. This recess is deep enough to permit the coin to
drop through as shown in Figure 3. When the bolt is drawn back again the
locking nose of the latch 6 will slide over the inclined ends of the coin recess d¹,
whereupon it will catch again into the recess d and arrest the bolt until a fresh
coin is introduced.
む
The mechanism may be mounted in a suitable box or case r, where the bolt is also
properly guided, as indicated in the drawing.
In Figures 5 and 6 this device is shown as applied to a bicycle stand; " is the box
which contain and guides the coin controlled bolt a, and s is a box containing a lock
for securing the bolt when it is pushed through. As indicated by dotted lines, the
bicycle is placed with one wheel between the boxes r and s and the bolt a is pushed
through after a coin has been dropped into the slot, where upon the bolt may be fixed
in this position by the lock. As will be seen from Figure 6 of the drawing, I have
here made the bolt a of two parts jointed together, so that the bolt will not stand so
far out from the apparatus when it is not in use. In Figures 5 and 6 is also shown
a device for securing the bicycle lamp together with the bicycle. The box is
provided with a carrier h upon which may be placed the lamp. When the bolt is
pushed in to secure the wheel of the machine a lip or projection a" engages over the

page_text: free end of the part h which is carrying the lamp 1, so that this cannot be lifted off
again until the bolt has been withdrawn. The carrier part for the lamp may also be
fixed to the end of the bolt a and the box ? provided with the lip or projection in
such manner that the lamp is carried by the bolt and that the free end of the carrier
arrives underneath the said lip or projection upon the box when the bolt is
pushed in.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, what I claim as my invention
and desire to secure by Letters Patent is:-
1. Coin controlled device, consisting of a pivoted, spring operated pawl or latch b,
which arrests the part to be liberated by the introduction of a coin by engaging into
a recess d of this part: this pawl or latch b provided with a slot e situated opposite a
recess of the part to be liberated, permitting the coin to enter and rest between
the latch b and the part to be liberated in such manner that when this latter part is
moved in the right direction, the inclined end of the recess d¹ will turn aside the
coin, and thereby disengage the latch 6 from the recess & substantially as described.
2. In a device of the kind herein described the combination with the latch 6 of a
bolt & and a carrier for a bicycle lamp, attached either to the box in which the
bolt is guided or to the end of the bolt a, said carrier to co-operate with a lip or pro-
jection either upon the end of the bolt a or the box for securing the lamp when the
bolt is pushed in, substantially as described.
