PROVISIONAL SPECIFICATION.
Improvements in or relating to Locks and Indicators Combined and
otherwise.
We, WILLIAM PARRY No 64, Caelleppa, Bangor Carnarvonshire (Builder) and
RICHARD GRIFFITHS Stanley House, Penmaenmawr, Carnarvonshire. (Watch-
naker) do hereby declare the nature of this invention to be as follows, and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
Our invention has reference to Locks and consists in constructing them in such
manner that an outside knob, handle, or other like device for opening, or drawing
back the bolt of said locks is normally disconnected from or out of gear with such
bolt so as to be incapable of acting thereon but, can be put into gear or communication
therewith by means of a penny or other coin dropped into the lock through a slot or
opening provided for the purpose.
The invention is specially intended for the locks of the doors of Water Closets at
Railway Stations, or other places; it enables a person to gain admission on payment
of the required charge, without the employment of a special attendant to receive the
money and, simultaneously, the Indicating Plate announces the engagement of the
Water Closet and, on the person again leaving, announces the disengagement of the
Water Closet.
In order that our invention may be better understood we will describe the saine
more in detail by making reference to the accompanying Drawings
Figure 1. represents the interior of the Lock, having opened the dust plates.
Figure 2. is a similar representation of the Lock shewing an alternative method of
working the Indicator.
Figure 3. is an end elevation of lock where the indicator is worked by means of the
Lock bolt.
Figure 4 is an end elevation Lock where the Indicator is worked by means of its
own bolt.
Figure 5 is a section through the Lock and door.
Figure 6 is the elevation to the outside, or front of the door, and shews the
indicating plate.
Figure 7. is the elevation to the inside or back of the door.
In all the figures, similar parts are indicated by similar letters.
On the outside, or front of the door, we cause an opening slot A in the indicating
plate A, the length and thickness of a penny, or other coin, to be cut or formed
and, through which the penny, or other coin, is passed into a sloping compartment B,
which is fixed to the back dust plate () and fits into an opening, or slot in the door
and, the penny, or coin, passing through this compartment and having reached the
end falls through a slot D, which is so constructed as to make the penny, or coin,
drop vertically into and through a corresponding slot E, in the spindle F (to which
on the outside, or front of the door, is attached the knob handle, or other such
device G,) and the penny, or coin, having dropped through the slot. E comes in
contact with a groove H, in the lock bolt J, which is placed at such a distance from the
spindle F as to prevent the penny, or coin, being quite released from the compart-
ment E in the spindle F, thus forming the connection between the spindle F and the
lock bolt J.
By turning the knob handle, or other such device G, the penny or coin, causes the
lock bolt J to move backwards about half its opening distance before it (the penny or
coin is released entirely out of the compartment. E in the spindle E.

page_text: The penny, or coin, on being released from the compartiment E, in the spindle F,
and the groove H, on the lock bolt J drops into the compartment K, specially made to
receive it, and which is opened as required from the interior, by means of a key,
fitting a specially made lever Lock L.
Simultaneously with the absolute release of the penny, or coin, from the compart-
ment E, in the spindle F, a catch M on the lock bolt J comes in contact with a catch N
on the spindle F, which, by the turning of the spindle F, by means of the knob handle,
or other such device G, completes the full backward movement of the lock bolt J,
thereby unlocking the door and directly the knob handle or device G is released, it,
(the knob handle or device G) is at once forced back to its original position, by
means of a spring O forcing a portion P of the catch N (and which is a part of the
spindle F) back to its original position against the compartment B. A check pin R
is fixed on the back dust plate () to prevent the spring O being forced any further
than required. The catch V having driven the catch M on the lock bolt J back
sufficiently far to allow for opening the door it slips over and the lock bolt J is forced
back into position by a spring S and cannot again be pushed back from the outside by
turning the handle knob or other said device G, unless another penny, or coin, he
inserted in the slot A, in the indicating Plate A', but the door bolt J may be moved
backwards from the inside, when required, by means of a knob handle, or other such
device T, which may either be fastened to the lock bolt J and work as a slide handle, or
knob, as shewn working in a groove U, or the lock bolt J may be moved back by
means of a turning handle, or knob working on the lock bolt, by means a catch, as in
ordinary door locks. The door, however, can be opened by a key fitting an ordinary
or special lock V, which mode of opening is intended for the official or attendants.
The Indicator is worked as follows:-To the lock bolt J is attached a vertical bar, or
connection B', which has a bent arm C¹, at the end of which is a loose click D¹, dropping
into a ratchet wheel E' connected with the four fangs F¹ of the Indicator on each of
which appear the letters DIS and which correspond with the word ENGAGED on
the Indicating plate A¹ on the front or outside of the door. The teeth of the ratchet
wheel are so arranged that by one movement of the Click D¹ the Fangs F¹ move round
half the opening G₁ on the indicating Plate A¹, consequently two movements of the
lock bolt J (viz.) -one on opening the door by entering and one on closing the door
after entering) cause the ratchet (which is connected with the fangs) to move the
fangs F¹ twice, which completes their entire disappearance from the opening G' on
Indicating Plate A¹, thereby leaving the word engaged only to be seen on the said
Indicating Plate, and simultaneously one of the fangs F¹ covers the slot A, conse-
quently, when the Indicating Plate shews the word engaged, it is impossible to insert
a penny, or coin, into the slot A.
Then, on a person opening the door to leave the W.C. one movement of the bolt J
causes the ratchet E' to move the Fangs F¹, so as to half cover the opening G¹, and,
on the door closing again, the bolt J causes the ratchet E to move the Fangs F¹, the
remaining half of the opening G¹, thereby fully exposing the letters DIS in front of
the word engaged on the Indicating Plate i.e. shewing that the Water Closet is Disen-
gaged and simultaneously the slot A is left perfectly open ready for the reception of
another penny or coin.
The Fangs F are connected with the ratchet wheel E¹ by means of a telescopic
spindle H, which can be shortened or lengthened to suit the thickness of the door; the
two are then tightened together by means of a screw J¹.
The Fangs Fare fastened in their exact position in the telescopic spindle H¹, by
means of a screw K¹.
The Indicator we prefer, however, to work independently of the lock bolt and to
effect this, instead of the arm B₁ we have an indicating bolt L' which works in and
out of a socket plate M¹--this bolt is so arranged that its action on the ratchet and
fangs is exactly similar to that of the Lock bolt as before described.
The Indicator can be placed in other positions than shewn and need not necessarily
form part of this particular lock, but may be adapted separately to other Locks.

page_text: Having now fully described the nature of our invention and the modus operandi of
the working of the same, we declare that what we claim is as follows:-
1st. The utilization of the penny, or coin, as the medium forming the connection
between the spindle (attached to the outside Handle) and the lock bolt in the manner
shewn and as described.
2nd. The method of working the Indicator, announcing the engagement or otherwise
of the apartment on the door of which it may be fixed as shown in Figure 1 and also
the alternative method as shewn in Figure 2.

We, WILLIAM PARRY, No. 64, Caelleppa, Bangor, Carnarvonshire (Builder) and
RICHARD GRIFFITHS Stanley House, Penmaenmawr, Carnarvonshire (Watchmaker) 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 :-
Our invention has reference to Locks, and consists in constructing them in such
manner that an outside knob, handle or other like device for opening, or drawing
back the bolt of said locks is normally disconnected from or out of gear with such
bolt so as to be incapable of acting thereon, but can be put into gear or communication
therewith by means of a penny, or other coin, dropped into the lock through a slot, or

of the required charge, without the employment of a special attendant to receive the
money and, simultaneously the Indicating Plate announces the engagement of the
Water Closet and, on the person again leaving, announces the disengagement of the
Water Closet.
In order that our invention may be better understood we will describe the same
more in detail by making reference to the accompanying Drawings
Figure 1. represents the interior of the Lock having opened the dust plates.
Figure 2 is a similar representation of the Lock shewing an alternative method of
working the Indicator.
Figure 3. is an end elevation of lock where the indicator is worked by means of the
Lock bolt.
Figure 4 is an end elevation Lock where the Indicator is worked by means of its

Figure 5 is a section through the Lock and door.
Figure 6. is the elevation to the outside, or front of the door, and shews the indicating
plate.
Figure 7. is the elevation to the inside or back of the door.
In all the figures, similar parts are indicated by similar letters.
On the outside, or front of the door, we cause an opening Slot A to be made in the
indicating Plate A', the length and thickness of a penny, or other coin, to be cut or
formed and, through which the penny, or other coin, is passed into a sloping com-
partment B which is fixed to the back dust plate C and fits into an opening, or
slot in the door and, the penny, or coin, passing through this compartment and having
reached the end falls through a slot D, which is so constructed as to make the penny,
or coin, drop vertically into and through a corresponding slot E, in the spindle F
(to which on the outside, or front of the door, is attached the knob handle, or other
such device G) and the penny, or coin, having dropped through the Slot E comes in

page_text: contact with a groove H in the lock bolt J, which is placed at such a distance from
the spindle F as to prevent the penny or coin; being quite released from the compart-
ment E in the spindle F, thus forming the connection between the spindle F and the
lock bolt J.
By turning the knob handle, or other such device G, the peniny or coin, causes the lock
bolt J to move backwards about half its opening distance before it (the penny or coin)
is released entirely out of the compartment E in the spindle F.
The penny, or coin, on being released from the compartment E, in the spindle F
and the groove H, on the lock bolt J drops into the compartiment K, specially made to
receive it, and which is opened as required from the interior, by means of a key,
fitting a specially made lever Lock L.
Simultaneously with the absolute release of the penny, or coin, from the compart-
ment, E, in the spindle F, a catch M on the lock bolt J comes in contact with a catch N
on the spindle F, which, by the turning of the spindle F, by means of the knob-
handle, or other such device G, completes the full backward movement of the lock
bolt J, thereby unlocking the door and directly the knob handle, or device G is released,
it, (the knob handle or device G) is at once forced back to its original position, by
means of a spring O, forcing a portion P of the catch N (and which is a part of the
spindle F) back to its original position against the compartment B. A check pin R
is fixed on the back dust plate U to prevent the spring 0 being forced any further
than required. The catch N having driven the catch M on the lock bolt J back
sufficiently far to allow for opening the door it slips over and the lock bolt J is forced
back into position by a spring S and cannot again be pushed back from the outside
by turning the handle knob or other said device G unless another penny, or coin, be
inserted in the slot A, in the indicating plate A¹, but the door bolt J may be moved
backwards from the inside, when required, by means of a knob handle, or other such
device T, which may either be fastened, to the lock bolt J and work as a slide handle,
or knob, as shewn working in a groove U, or the lock bolt J may be moved back by
means of a turning handle, or knob working on the lock bolt, by means of a catch,
as in ordinary door locks. The door, however, can be opened by a key fitting an
ordinary or special lock V, which mode of opening is intended for the officials or
attendants.
The Indicator is worked as follows:-To the lock bolt J is attached a vertical bar, or
connection B¹, which has a bent arm C', at the end of which is a loose click D', dropping
into a ratchet wheel E¹ connected with the four fangs F1 of the Indicator on each of
which appear the letters DIS and which correspond with the word ENGAGED
on the Indicating plate A¹ on the front, or outside of the door. The teeth of the
ratchet wheel are so arranged that by one movement of the click D¹, the fangs F¹
move round half the opening G¹ on the indicating Plate A', consequently two move-
ments of the lock bolt J, (viz. :-one on opening the door by entering and one on
closing the door after entering) cause the ratchet (which is connected with the fangs)
to move the fangs F1 twice, which completes their entire disappearance from the
opening G¹, on Indicating Plate A', thereby leaving the word engaged only to be seen
on the said Indicating Plate, and simultaneously one of the fangs F covers the slot A,
consequently, when the Indicating Plate shews the word engaged, it is impossible
to insert a penny, or coin, into the slot A.
Then, on a person opening the door to leave the W.C. one movement of the bolt J
causes the ratchet E¹ to move the fangs F¹, so as to half cover the opening G₁ and, on
the door closing again the bolt causes the ratchet E¹ to move the fangs F¹, the
remaining half of the opening G₁ thereby fully exposing the letters DIS in front of the
word engaged on the Indicating Plate i.e. shewing that the Water Closet is
Disengaged and simultaneously the slot A is left perfectly open ready for the reception
of another penny, or coin.
The Fangs are connected with the ratchet wheel E¹ by means of a telescopic
spindle H¹ which can be shortened or lengthened to suit the thickness of the door,
the two are then tightened together by means of a screw J¹.

page_text: The Fangs F¹ are fastened in their exact position in the telescopic spindle H' by
means of a screw K¹.
The Indicator we prefer, however, to work independently of the lock bolt and, to
effect this, instead of the arm B' we have an indicating bolt L', which works in and
out of a socket plate M-this bolt is so arranged that its action on the ratchet and fangs
is exactly similar to that of the Lock bolt as before described.
The Indicator can be placed in other positions than shewn and need not necessarily
form part of this particular lock, but may be adapted separately to other Locks.
Having now fully described the nature of our invention and the modus operandi of
the working of the same, we declare that what we claim is as follows:-
1st. The utilization of the penny, or coin, as the medium forming the connection
between the spindle (attached to the outside handle) and the lock bolt in the manner
