Improvements in and relating to Coin Freed Locks and Mechanism.
I, JONATHAN HURN FAULKNER, of 50 Newgate Street, in the City of
London, Hotel Proprietor, do hereby declare the nature of this invention to be as
follows:-
My invention relates to apparatus intended principally for attachment to the
doors of water closets, but applicable to other purposes and comprises a coin-
controlled lock to which may be added other apparatus for controlling the
movements of the door when the lock has been operated.
The lock has two handles, one on the outside of the door and another on the
inside. That on the outside operating the bolt through the coin freed mechanism,
that on the inside operating the same bolt independently of the coin mechanism
and also serving to draw down from the coin slot an arm by which it is temporally
closed so as to open the slot for the reception of another coin. The lock is also
provided with a key which operates the same bolt without interfering with the coin
receiving apparatus.
The dropping in of a coiu enables the outer handle to be turned so that a person
may enter, the coin remains on the coin-lever so that the lock may be operated by
the outside handle until this has been turned so far as to disengage the latch or bolt
and allow the door to be opened, the coin then drops into its receptacle and the
door being closed, the coin slot is closed by an internal arm until the door is
opened by the handle on the inside of the door which operation opens the coin slot
again.
The upper part of the lock has an opening of proper dimensions for admitting
the insertion of a coin, say a penny, and a balanced coin lever, on the tail end of
which the coin falls, and which it depresses, thereby raising the other end of the
lever and removing it, or a projecting part of it out of the line traversed by a
projection on the follower or hub which is operated by the outer handle of the
door.
Within the lock and just below the coin-slot I may arrange a guide piece to
conduct the coin on to the said lever-tail and I may employ another balanced lever
so arranged as to allow a coin to pass in or downwards and to prevent the coin
being drawn back after it has once passed and while it is on the before mentioned
coin lever.
The follower or hub operated by the door bandle is provided with a projection
or shoulder which corresponds and engages with the coin lever or projection thereon
above described. It has also an arm which operates the catch or bolt and another
arm which when the handle is turned to open the door touches a finger on the coin
lever and thus insures the descent of the latter at the same moment as it is set free
to descend by the movement of the stop lever described in the next paragraph.
This arm also engages and operates an arm carrying a plate preferably bearing the
word "Engaged' or the like which it raises to the level of the coin slot so as to
prevent the insertion of another coin while the closet is occupied.
Between the coin lever and the bolt is a moveable stop which is one end of a
lever, and which normally prevents the descent of the tail end of the coin lever
low enough to allow the coin to pass it and drop into the receptacle beneath. The
other end of the stop lever is operated by a projectiou on the bolt so that when the
bolt is drawn back by turning the handle the tail end of this stop lever is carried
backwards by the bolt and the other end thereby moved away from the coin lever
which latter then drops and allows the coin to pass downwards.
The arm which closes the coin slot and exhibits the word "Engaged," and which

page_text: is raised by the turning of the outside handle may conveniently be retained in the
raised position by the friction of a spring on its surface but when the person is
about to pass out from the closet and opens the door by the inner handle, a part of
the follower or hub operated by this handle or a projection on it operates a tail
piece connected with the arm and lowers it out of sight. In some cases it may be
found desirable to have the apparatus so arranged that the door of the closet is
normally open and so that a penny must be placed in the slot before it can be
closed and this I accomplish by adding a bolt reaching to the top, or bottom of the
door and taking into the floor or into a quadrant, or the like below or above, such
bolt being connected with and operated by the parts of the lock hereinbefore
described.

Improvements in and relating to Coin Freed Locks and Mechanism.
I, JONATHAN HURN FAULKNER, of 50 Newgate Street in the City of London,
Hotel Proprietor, 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 :-
My invention relates to apparatus intended principally for attachment to the
doors of water closets, but applicable to other purposes, and comprises a coin'
controlled lock to which may be added other apparatus for controlling the move-
ments of the door when the lock has been operated.
In the accompanying drawings
Figure 1. is a front elevation of my said lock attached to a door; Figure 2. is a
plan of the same ;
Figure 3, is an elevation showing the front covering plates removed and the
mechanism exposed. The various parts being shown by the full lines in their
normal position and by the dotted lines in the position they assume after a penny
has been dropped in and before the handle of the lock has been turned. Figure 4,
represents the same with the inner covering plate in position ;
Figure 5, is a section on the line x. y.
Figure 6, is a section on the line v. w. showing the hooks and studs by which the
outer covering plate is secured at its upper edge.
Figure 7, is an elevation, with the covering plates removed, showing the position
of the mechanism when the handle on the outside of the door is turned in order to
open the door, and the bolt is consequently drawn inwards to its furthest limit and
the penny has just dropped from the coin lever and the arm carrying the word
Engaged has risen to cover the opening.

Engaged." Figure 84, is a side elevation of the same.
•
Figure 9, is a side elevation of the coin lever. Figure 94, is a plan view of the
same.
Figure 10, is a side elevation, and Figure 104 a plan view of the bolt.
Figures 11 and 114, are respectively a side and an end elevation of the follower
or hub operated by the handle on the outside of the door;
Figures 12 and 12^ are respectively a side and a front elevation of a stop lever
which regulates the descent of the coin lever.
Figure 13, is an elevation of an attachment comprising a bolt operated by the
lock and engaging with a catch or quadrant at the top or bottom of the door (the
drawing represents it at the top). Figure 14, is a section of the same. Figure 16,
is an elevation of the same from the inner side the covering plate being removed to
show the mechanism.

page_text: Figure 16, is a door with the lock and bolt attachment affixed; and Figure 17
is a plan of the same showing the quadrant.
The lock has two handles, one A, on the outside of the door, and another B, on
the inside. That on the outside, A, operating the bolt c. through the coin freed
mechanism, that on the inside, B, operating the same bolt, c, independently of the
coin mechanism and also serving to draw down from the coin slot D., an arm or
shutter d, by which it is temporarily closed, so as to reopen the slot D. for the
reception of another coin. The lock is also provided with a key for the use of the
attendant only working in the hole which operates the same bolt c. without
interfering with the coin receiving apparatus.
The dropping in of a coin enables the outer handle A to be turned so that a person
may enter, the coin remains on the coiu lever so that the lock may be operated by
the outside handle until this has been turned so far as to disengage the latch or
bolt c. and allow the door to be opened, the coin then drops into its receptacle, and
the door being closed, the coin slot is closed by an internal arm or shutter d.
until the door is opened by the handle on the inside of the door, which operatio:
opens the coin slot again.
The upper part of the lock has a coin slot or opening D of proper dimensions
for admitting the insertion of a coin, say a penny, and a balanced coin lever G, on
the tail end of which the coin falls, and which by its weight it depresses, thereby
raising the other end of the lever so that a projecting part of it, or stop piece, g³ is
raised out of the line of motion of the projection . on the hub of the follower H
which is operated by the outer handle A. of the door, thus allowing the outer
handle A. to be turned so that the latch or bolt c. is drawn back and the door may
be opened. The coin, when it falls on the coin lever, rests thereon between two
wings one of which has its upper part bent slightly over to enable it to
clear the coin guide C. by which the coin is guided from the slot on to the coin
lever.
.
Just above the coin lever is a balance lever E, one end of which moves down-
wards when a coin is inserted so as to allow the coin to pass in and downwards, and
which as soon as the coin has passed it, returns to its former position and prevents
the coin being fraudulently drawn back after it has operated the coin lever and
before it has passed away from it.
The follower or hub H. operated by the handle A. on the outside of the door.
and which is shown separately in Figures 11 and 11^, is provided with a projection
or shoulder h. which corresponds and engages with the projecting part or stop
piece g³ of the coin lever. It is also provided with an arm h' which operates the
latch or bolt c., also another arm which when the handle A is turned to open.
the door moves away from the upper end of the coin lever G and allows the other
end of it to drop on to the stop lever F, and then touches a finger g' on the coin
lever and thus insures the descent of the latter at the same moment as it is set free
to descend by the movement of the stop lever F, hereinafter described.
+
The arm also, as the handle is being turned, strikes the part j. of the lever J,
and operates it, carrying the plate or shutter d, preferably bearing the word
"Engaged," to the level of and behind the slot D, so as to close it and prevent the
insertion of another coin while the closet is occupied. This lever J. is kept in this
position and prevented from dropping by the pressure and friction of a spring k,
which is attached to the covering plate K.
Between the coin lever and the bolt is a movable stop lever F, one end of which
prevents the tail end of the coin lever descending low enough to allow the coin
to pass by it to the receptacle beneath until the handle A is turned far enough to
admit of the door being opened. The lower end of this stop lever F is operated
by a projection m, on the bolt c, so that when the bolt is drawn back by the
turning of the handle, the tail end of this stop lever is carried backwards and the
other end thereby moved a little downwards, away from the coin lever G, so as to
allow the latter to drop far enough to let the coin pass downwards. u is a stud
and threaded sleeve for supporting the covering plate K and receiving the

page_text: threaded part of the screw which secures the plate. This also serves as a stop.
against which a projection f' on the lever F rests thereby limiting the movement
of the lever F in that direction.
n on the.
The lever J remains in position to cover the coin slot while the closet is
occupied, but when the handle B which is on the inside of the door is turned in
order to open the door that the occupant may pass out, a projection
follower N strikes a projection j' on the lever J and carries it backwards, thereby
lowering the arm or shutter marked "Engaged," and leaving the slot open for the
insertion of the next penny. The striking plate t, for the bolt c is arranged as
shewn in Fig. 2, and has a projecting edge t' which just meets the edge of the
lock so as to prevent the insertion of a knife or the like for the purpose of pushing
back the bolt c and opening the door without paying.
In some cases it is desirable to so arrange the apparatus that the door is
normally wide open and can be closed only after the insertion of a penny in the
slot. In order to accomplish this I make the end of the arm h long enough to
project through a slot in the back of the lock as shewn in Figs. 5 and 11, and
through a slot P in the plate P see Figs. 13, 14 & 15 to operate a bell crank
lever which is maintained normally in the position shewn by the spring R¹.
The crank is jointed to a bolt R the upper end of which projects above the
upper edge of the door and engages in a hole or recess in the quadrant S and
thereby holds the door open.
The closet door being thus normally open a person desiring to use it can enter
freely but cannot shut the door until he places a penny in the slot which releases
the mechanism as already described and allows the handle A to be turned. This
operates the lock as hereinbefore described and by the action of the lever h³ on
the crank Q which it presses backwards against the spring R', draws down the
bolt R and sets the door free to be closed. This being done the door cannot be
opened from without (except by the attendant's key) for the slot is closed by the
plate marked "
Engaged" and the outer handle A cannot be turned. The user
on leaving the closet turns the inner handle B which reopens the coin slot as
before described, and the door being opened far enough the bolt R engages in
the quadrant S, and the door is again fixed open until another coin is put in
the slot.
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:
1. The improvements in and relating to coin freed locks and mechanism herein
before described and shewn in the drawings.
2. A coin freed lock for water closets and similar situations in which the cycle
of movements is commenced by the insertion of a coin in a slot on the outer side
of the door followed by the turning of the outer handle, and is completed by the
opening of the door by means of the inner handle and closing the door substantially
as described.
3. A lock for doors and the like through which the user has to pass to and
forth as in the case of water closets and similar places, operated first by the
insertion of a coin which sets free the handle on the outside of the door the
turning of which passes the coin into the receptacle and closes the coin slot, and
then by the turning of the handle on the inner side of the door by which the door
is again opened and the shutter of the coin slot operated substantially as herein-
before described.
4. In a lock such as described the lever J operated first by the outer handle to
close the shutter and then by the inner handle to reopen it substantially as
described and shewn in the drawings.
5. In a lock such as described the combination of the lever J with the armed
followers H and N substantially as described and shown.
6. In a lock such as is described the combination of the bolt c adapted to be

page_text: operated by the handles A and B with followers H and N and by a key such
bolte having a projection m, and the follower H having a projecting stop h and
arms and h, the follower N having a projection n all for the purposes described
and substantially as shewn in the drawings.
7. In a lock such as described the combination of a coin lever G having
wings g and g³ a stop 9 and finger g' a follower H with a projection hand
arms and, a lever F to control the descent of the coin lever G, with
projection adapted to be operated by the bolt c and to control the descent
of the coin lever all as described and substantially as shewn in the drawings.
8. The arrangement shewn in Figs. 13, 14, 15, 16 and 17 by which the above
described apparatus is made applicable to a door kept normally open, consisting of
a bolt R quadrant S crank Q and spring R' substantially as described and
shown.
