PROVISIONAL SPECIFICATION.
Improvements connected with Coin Freed Appliances for Locks or
Fasteners of Lavatories and like places.
I, FREDERICK JOHN BEAUMONT, of 27, Albany Road, Stroud Green, Finsbury
Park, London, Engineer, do hereby declare the nature of this invention to be as
follows:
This invention has for object, adapting appliances of special manufacture to
locks, latches, and like fasteners of coin freed apparatus used with the doors of
lavatories and like places, so that any form of lock or catch can be employed.
The invention consists of a disc plate or box with one or more slots to suit the
charges made for entry.
The unemployed slots can be covered by an adjustable back plate. The back
plate has a chute or pocket for receiving and holding the predetermined coin,
which when the disc is turned by a handle comes against a flag or swing plate
having its free end weighted, so that the pressure swings the plate out of the way
for the coin to press against a trigger to free the lock or catch bolt clear of the
hasp or box, the door being simultaneously opened as the handle is being turned
to its extreme limit, by which time the flag has returned to its normal position
for the reception of the next coin. The disc turns in one direction only for the
opening operation, its return movement being by balance weight, spring, or
other appliance, as at present.
A half-turn of the dise will be sufficient for each opening of the door for en-
trance, and the other half-turn on exit, the coin being then discharged from the
chute into the till. This half-turn motion can be governed by catch plates engag-
ing teeth or notches of the disc chute or back plate.

Improvements connected with Coin Freed Appliances for Locks or
Fasteners of Lavatories and like places.
I, FREDERICK JOHN BEAUMONT, of 27, Albany Road, Stroud Green, Finsbury
Park, London, Engineer, 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:-
This invention has for object, adapting appliances of special manufacture to
locks, latches, and like fasteners of coin freed apparatus used with the doors of

page_text: lavatories and like places. so that any form of lock or catch can be employed.
The invention consists of a disc plate or box with one or more slots to suit the
charges made for entry. The unemployed slots can be covered by an adjustable
back plate. The back plate has a chute or pocket for receiving and holding the
predetermined coin, which when the disc is turned by a handle comes against
a flag or swing plate having its free end weighted so that the pressure swings the
plate out of the way for the coin to press against a trigger to free the lock or
catch bolt clear of the hasp or box, the door being simultaneously opened as the
handle is being turned to its extreme limit by which time the flag has returned
to its normal position for the reception of the next coin.
The disc turns in one direction only for the opening operation, its return move-
ment for discharge of the coin being by balance weight, spring, or other appli-
ance attached to the locking catch or bolt and operating same as at present.
A half turn of the disc will be sufficient for each opening of the door for en-
trance and a half turn of a handle inside the door on exit. The return motion
of the coin receiver can be governed by catch plates engaging teeth or notches
of the disc chute or back plate.
My invention will be clearly understood by the annexed drawings in which
Figure 1 is an elevation of a complete coin freed lock with the plate covering
the mechanism removed, and showing such mechanism in position for receiving
the desired coin.
Figure 2 is a side sectional elevation affixed to a door and showing the position
of the outside and inside operating handles, also the locking bolt which carries
the indicator.
Figure 3 is a similar view to Figure 1 but showing the mechanism in the posi-
tion with the coin when the lock or catch is operated.
Figure 4 is a front elevation of a complete lock.
A is a slotted spindle carrying two plates B, B, having guides or walls C C,
to form a coin receptacle. This spindle A is pivoted to the back plate D and to
the front plate E from where it projects for carrying a handle F.
The casing is formed with a circular track G which has an opening H and adja-
cent thereto is pivoted a weighted flag I whose nose projects within the circular
track G and between the plates B, B, for the purpose hereinafter explained. One
or both of the plates B, B, have notches into which ratchet pawls J controlled by
springs K can enter, so as to prevent a full half return movement of the plates
and to hold them in their proper position for receiving a coin.
Adjacent to this circular track G is fitted a lock which may be of any construc-
tion, but for the purpose of illustration consists of a bolt L controlled by a spring M
and provided with the usual handle N and operating cams or wipers. To this
bolt L, I provide a pin P which engages one end of a lever or trigger Q (pivoted
to the casing), the other end projecting within the track G for the purpose here-
inafter described:
R is a lever or arm which is pivoted on the spindle A and marked with the
indication "engaged" and "vacant" the portion bearing the indications riding
in a curved slot situate preferably outside the top portion of the track G. The
lever or arm R is also provided with a projecting pin S which engages with the
spindle T of a locking bolt U, so that on a person inside the door actuating the
handle V for shooting the bolt U to lock the door, will actuate the lever R and
expose the word "engaged" to the outside of the lock, and on the reverse move-
ment of the handle for unlocking the door will expose the word "
vacant."
W is the money receiving portion of the apparatus accessible by a door X.
A coin is inserted in the coin slot Y and passes through one of the slots Z of
the front plate B resting upon one of the stops a, a, of one of the guides C. The
handle F is now operated and the coin travels in its pocket around the track G
and when the handle is turned about half round, the coin comes in contact with
the nose of the flag. I and in so doing will depress the nose to close the opening H,
as shown in dotted lines in Figure 3 the coin in so doing passing over same, the

page_text: flag I then resuming its normal position immediately the coin has passed. The
coin still travelling next comes in contact with the projecting end of the lever or
trigger Q, as shown in Figure 3, and acting against same will cause the opposite
end to actuate the lock bolt L and thus free the door for opening. The coin can
travel no further in this direction, and on the pressure of the handle F being
removed the spring M through the bolt L will return the trigger Q to its normal
position and in so doing the coin and plate B will be returned until the coin
comes opposite the opening H through which it falls into the coin box W, the
flag I having returned to its normal position for freeing said opening, and at
the same time prevent any possible return travel of the handle and consequent
replacement of the coin in its original position for fraudulent extraction through
the slot Y.
The door having been unlocked and opened, the person enters the room or
chamber and in so doing closes the door behind him the catch L giving way and
locking the door in the usual manner, and to indicate outside the door that the
room or chamber is engaged the handle V is moved to shoot the bolt U into its
recess in the hasp or door stile and at the same time exhibit outside the indica-
tion engaged" showing that the room or chamber is occupied, and when the
person desires to leave the room or chamber, action on the handle V will remove
the bolt U from the hasp or door style and exhibit the word "vacant" and a
turn on the handle N will free the bolt L to enable the door to be opened.
<<
Should a smaller coin than the size intended to be used with the apparatus be
inserted in the coin slot Y it will not rest on the stop a, but will pass same and
through the slot in the spindle A and drop into the money box W, so that the
mechanism cannot be operated.
Thus it will be seen that the handle F is given rather more than a half turn
for each operation and the spring M through the bolt L and trigger Qreturns
the handle F to its half turn position for a fresh operation on the insertion of
another coin in the other slot Z of the front plate B and at the same time discharg-
ing the previously inserted coin into the money box W.
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. The improvements connected with coin freed locks or fasteners of lava-
tories and like places, whereby on the insertion of a predetermined coin and the
actuation of a handle the coin can be made to travel around a circular track and
in so doing depress and pass over the nose of a free hanging flag for closing an
opening in the track and actuating a trigger connected with a locking bolt for
removing such bolt from contact with the hasp or door stile to free the door, and
the coin be returned to the opening created by the flag having returned to its
normal position for passage to a money till, substantially as set forth.
2. In coin freed locks or fasteners of lavatories and like places, the employ-
ment of a freely suspended flag having its nose projecting within the track
whereby on the passage of the coin to actuate a trigger or other appliance con-
nected with a locking bolt a coin delivery opening is closed during such coins
travel over the nose of the flag, but is opened as soon as the coin has passed the
nose of the flag, as and for the purpose described.
3. In a coin controlled lock, the combination with the lock-bolt and actuating
means therefor, of a coin conveyor arranged to support and carry a coin in the
path of said bolt-actuating means so that said coin will engage said means to move
the bolt, and means for rotating said coin conveyor, substantially as described.
4. In a coin controlled lock, the combination with the lock-bolt and actuating
means therefor, of coin conveying discs arranged to support and carry a coin in
the path of said bolt-actuating means so that said coin will engage said means to
move the bolt, a track surrounding said dises and having an opening therein
adjacent to the bolt-actuating means, a device for closing said opening during

page_text: the passage of the coin thereover, and means for rotating said coin conveying
discs, substantially as described.

5. In a coin controlled lock, the combination with the lock-bolt and actuating
means therefor, of a pair of rotary coin conveying discs arranged to support and
carry a coin in the path of said bolt-actuating means so that said coin will engage
said means to move the bolt, means for rotating said dises in one direction, and
means for preventing backward rotation thereof, substantially as described.
6. In a coin controlled lock, the combination with the lock-bolt and actuating
means therefor, of coin conveying discs arranged to support and carry a coin in
the path of said bolt actuating means so as to engage said means to move the
bolt, a track surrounding the discs and having a coin outlet opening therein.
adjacent to the bolt actuating means, a pivoted flag arranged to be actuated by
a coin to close said opening during its passage thereover, means for rotating said
discs in one direction, and a pawl for preventing rotation of the discs in the oppo-
site direction, substantially as described.
7. In a coin controlled lock. the combination with the spindle A, having a
transverse coin slot therethrough of coin carrying discs mounted on said spindle,
a track surrounding the coin-discs and having an opening therein disposed below
the slotted spindle, a lock bolt, and actuating means therefor projecting into said
track in position to be actuated by the coin carried by the discs substantially as
described.
8. In a coin controlled lock, the combination with the lock-bolt and actuating
means therefor, of a coin conveyor arranged to positively move the coin over a
coin slot and into contact with the bolt actuating means to operate the bolt, a
pivoted flag arranged in the path of the coin and adapted to be actuated thereby
to close said coin slot during the passage of the coin thereover, and means for
operating the coin conveyor, substantially as described.
