Improvements in or relating to Locks for Cycle-racks, Clothes
Hooks, and the like.
A communication from R. WICKE AND COMPANY, of Dresden, Augsburgerstrasse, in
the Empire of Germany.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The lock for cycle-racks, clothes-hooks etc. illustrated by way of example in
the accompanying drawing is characterised by the bolt of the lock being held
back by a device whereby the securing of the bolt is prevented, until said locking
device is released by a coin. The device is also arranged so that the key cannot
be removed until the bolt.is locked, said key being held fast as long as the lock
is open. The locking device is of such construction that it can be mounted on
the cover of any lock without damaging it.
In the accompanying drawings Fig. 1 represents a lock or holder for securing
a cycle etc. when not in use, and consists of a casing containing the locking
mechanism and cash-receptacle, as well as of a hinged bracket one part of which is
fixed, the other being pivotted about it. At the front end of the latter there is
provided an eye, with which the latch of the lock is adapted to engage.
The cycle etc. to be secured is placed so that the movable part of the bracket
may be folded round the rim whereupon the latch of the lock springs in and
secures the cycle.
Fig. 2 shows a wardrobe holder for hanging up and securing overcoats, hats,
umbrellas or sticks. The upper bracket in this case is rotatable about its ver-
tical axis, i.e. in a horizontal direction. The lower double bracket on the casing
is also movable, about its horizontal axis, so that the fork at the lower end can be
moved towards the casing or away from it. An overcoat etc. can be first hung
over the central bracket and then the hat placed upon it while a stick or umbrella
(the handle of which must be in the form of a ring or knob or hook) is placed in
the forks of the lower bracket. Then the lower part is pressed towards the casing
so that the fork-ends lie close against it and the upper bracket is turned towards
the central one so that their ends touch or are in line. By locking the lock the
latch secures the movable brackets in position, so that none of the articles can be
removed from the brackets until the device is unlocked.
Figs. 3 to 8 show details of the locking mechanism.
As shown in the drawing the lock consists of two parts a a¹ pivoted about the
same pin 6 the ends of said parts being formed into tongs or hooks the jaws of
which hold the coin introduced and are thus coupled together for a combined or
joint movement.
The part a (Figs. 3 & 4) of the device rests with its rear projection in front
of the bolt d of the lock and prevents it from advancing into its "locked" posi-

page_text: tion. If a coin falls between the jaws of the parts a a¹ they hold the coin fast
and are coupled and move together, owing to the advancing bolt d depressing the
triangular projection of the part a¹ in passing along its cam-face. Consequently
the jaw of said part a¹ presses by means of the coin on the jaw of the part a and
causes the latter to participate in its movement, so that, the hook shaped projec-
tion at the other end of the part a moves back and allows. the advancing bolt d
to pass. The triangular projection of the part a¹ in the meantime will have moved
on the surface of the bolt d and engages a notch or groove e thereon (Figs. 7 & 8),
thereupon the jaws move apart and the coin drops between them and into the
receptacle. Two springs f f¹ press-the parts ad against the bolt d"
The lock can be opened with its key in the usual manner, and the shackles B
which were hitherto held by the bolts can be turned into their open position. The
person next putting in his bicycle (Figure 1) or clothes etc. (Fig. 2) and desiring
to lock them finds the key in the lock, but cannot close the parts B until he has
placed a suitable coin in the apparatus. Only when the coin is between the jaws
the locking device being in the position shown in Fig. 7 can the bolt be shot.
When the lock is secured the device is in the position shown in Fig. 8 the coin
having passed between the jaws. The lock can be opened with its key at any
time whereupon the part B is turned back into its open position and the cycle,
clothes etc. released..
יו
Having now particularly described and ascertained the nature of this invention
as communicated to me. by my foreign correspondent and in what manner the
same is to be performed I declare that what I claim is: -
1. A locking device a a¹ acting on the bolts of locks for cycle racks, clothes
hooks or the like the tong or hook like jaws of which are coupled by a coin intro-
duced to produce a simultaneous movement in order to allow an advance of the
bolt upon the key being turned substantially as described.
2. The combination and arrangement of parts constituting the complete lock-
ing device for the bolts of cycle-rack, clothes hook or like locks substantially as
described or illustrated in the accompanying drawings.
