Improvements in Locks and Fastenings for Lavatories and the like.
I, WILLIAM RITCHIE BAKER, of 9, Belmont Villas, Wallington, Surrey,
Gentleman, do hereby declare the nature of this invention to be as follows:
My improvements are principally designed for use with coin-receiving locks,
especially the one described in my Patent No. 2315, 1899, but they could be
adapted for use with other kinds of locks and fastenings.
To ensure the door of the closet being fastened whilst in use, I would fix an
indicator to the inside of the door, which would clearly show whether it was
bolted or not. It would be so constructed as to work in connection with the
handle, indicator, or interior bolt, and could be either an addition to the lock,
as the form described, in the before mentioned patent, or a modification or the
utilisation of some existing part of the mechanism, attention being drawn to its
position by a sign or such words as "bolted," "unbolted" or the like.
I would also further utilise the force employed in turning the handle by
causing this to actuate suitable mechanism that would deliver some paper, a
ticket or other article every time the handle was turned after a coin had been
placed in the slot. This might be accomplished by having an arm attached to
one of the spindles, or other suitable part, that would raise the paper from a
magazine attached to the door, but which for small articles might be enclosed
in the lock itself.
If the interior of the closet is badly lighted so that the indicator cannot be
seen, I would cause the wording on it to be written on grooved glass, with the
wood on the door cut away behind it.
Improvements in Locks and Fastenings for Lavatories and the like.
I, WILLIAM RITCHIE BAKER, of 9, Belmont Villas, Wallington, Surrey,
Gentleman, 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 improvements are principally designed for use with coin-receiving locks,
especially such as that described in the specification of my Patent No. 2315 of
1899, but they may also be adapted for use with other kinds of locks and
fastanince

page_text: And in order that the said invention may be fully understood I will
proceed to describe the same with the aid of the accompanying two sheets of
drawings.
To ensure the door of a closet, for example, being fastened whilst in use, I
fix an indicator inside the door which clearly shows whether the door is bolted
or not.
An arrangement of this kind is shown in Figure 1 of the drawings, in which A
represents an ordinary internal sliding bolt the face of which next the door
may be marked as usual with the words Vacant and Engaged either of which
is brought opposite an opening through the door according as the bolt stands in
the unbolted or in the bolted position in the manner now well understood. This
bolt A is provided with a toothed rack B which gears with a toothed pinion
turning freely on a pin D. This pinion C carries an index E the end of which
plays round a segmental dial on which are marked the words Bolted and Unbolted
as shown. It will now be understood that when the bolt A is in its drawn back
position as in the figure, the index E stands pointing to the word Unbolted and
that when the said bolt is in its shot out position the index E stands pointing
to the word Bolted thus indicating to the occupant of the closet whether the door
is bolted or not.
But this arrangement shows also whether the bolt A has been shot far enough
to effectually bolt the door, for as sometimes happens, as for example when the
wood work of the door or frame has shrunk or warped, the bolt fails to enter
the mortise or staple and the door is not in reality bolted although the bolt has
been partly shot. In this case when the end of the bolt A reaches the door
frame the index E stands pointing more or less closely to the line between the
words Bolted and Unbolted, that is to say in an indeterminate position which
indicates that the device has not properly acted. The bolt A may be operated
by moving the handle G to the right or left or by turning the index E in either
direction.
I sometimes construct and arrange this device so as to work in connection
with the handle, indicator or interior bolt of the lock described and illustrated
in the specification of my aforesaid Patent No. 2315 of 1899. Figure 2 of
the drawings hereto annexed show the said device connected with the indicator
slide of such a lock which is of the coin-receiving kind.
u is the said indicator-slide having the words Vacant and Engaged indicated
thereon which words show through an opening in the lock
well known way.
case in the
This indicator-slide is operated by the outer and inner
handles r and o of the lock in the manner described in the aforesaid specification,
by mechanisms not shown in my present drawing because they form no part
of my present invention, nor are they necessary for the elucidation of the
same. y is a spindle projecting through the back of the lock case and through
the door to the inside thereof. x is an index mounted on the inner end of the
said spindle and playing round a dial having the words Bolted and Unbolted
indicated thereon as described in reference to Figure 1. is an arm fixed
on the spindle y inside the lock case, and having in it a slot 1 which engages
with a pin 2 on the indicator-slide u. This indicator-slide u is provided with
a lateral projection or flange which, when the slide is in the position showing
Vacant through the opening in the lock case, uncovers the coin-slot so as to
allow a coin to be inserted; but which, when the slide is in the position showing
Engaged through the opening in the lock case covers or blocks the coin slot so as to
prevent the insertion of a coin while the closet is occupied. It will now be
understood that whenever the index arm a is moved to the right or left the arm l
is moved also, and acts by the pin 2 to move the indicator-slide, and vice versa,
when the said slide is moved the index is moved thereby. It will also be
understood that the index arm on the inside of the door is normally self-acting
that is to say is operated by the lock mechanism and points to Bolted whenever

page_text: the indicator-slide u is in the Engaged position; and will point to Unbolted
whenever the indicator-slide u is in the Vacant position, there being no necessity
for the occupant to touch the index-arm under ordinary circumstances. But
should the occupant for any reason open the door by the inside handle o, or
wantonly turn such handle, the indicator-slide u will be moved into and remain
in the Vacant position, rendering the entry of another person possible by the
introduction of another coin into the coin-slot. But such movement of the inside
handle o will also have caused the index-arm to point to the word Unbolted,
and the occupant can then turn the said arm to the Bolted position which will
at the same time move the indicator-slide into the Engaged position without
interfering with the position of any of the other mechanism of the lock.
The above described device for indicating whether the door is fastened or
not, that is to say whether it is so secured that no one can open it from the
outside either by turning the handle or inserting a coin into the slot, can also
be applied to coin-receiving locks of other construction besides that described
in my aforesaid patent and in which there may or may not be an indicator
slide connected with the lock for the purpose of indicating whether the closet
is vacant" ог
"engaged."

A modification of this kind is illustrated in Figures 3, 4 and 5 of the draw-
ings, in which Figure is a partial elevation of a coin-receiving lock as seen
from the door side of the lock case with the said device applied thereto; Figure 2
a partial plan of same, and Figure 4 a partial sectional elevation.
In this case the index E inside the door is mounted on an axis G which turns
in a bearing in the plate H of the lock case, and carries an arm I the upper
end of which engages between two projections or lugs J of a sliding plate K
so shaped, as shown in Figure 4 that when the index E stands pointing to the
word Unbolted indicated on the inside of the door, the coin-slot L is open for
the introduction of a coin but when the index E stands pointing to the word
Bolted the plate K will have been moved to the left by the action of the arm I
on the lugs J so that the full part of the plate K comes under the slot
prevents the introduction of another coin until the index E has been moved back
so as to point to the word Unbolted.
and
In this arrangement if the occupant left the closet and closed the door after
him without moving the index E from the Bolted position to the Unbolted
position the coin-slot L would remain closed by the plate K, and entrance could
not again be obtained by the insertion of a coin until the said plate K had been
drawn back into the position shown in Figure 4 by means of a special key or
some such device applied to the axis G. To obviate this inconvenience I fix
a pin M to the latch bolt B of the lock in such a position that it commands the
lower end I of the arm I so that when the said latch-bolt N is moved inwards
by the act of closing the door the said pin M presses against the said lower
end I and turns the inlex E automatically. into the Unbolted position and
thereby brings the plate K into the position shown in Figure 4 leaving the
coin-slot L free to receive another coin.
I also utilize the force employed in turning the handle by causing this to
actuate suitable mechanism that delivers paper, a ticket or other article every
time the handle is turned after a coin has been placed in the slot.
An arrangement of this kind is illustrated in Figure 6 of the drawings, which
shows a sectional elevation of a box fixed for example inside the door of a water-
closet and containing small packets of folded papers one of which packet is
placed at the disposal of a person using the closet.
o represents the spindle of the lock handle projecting into the paper box P.
Qis an arm secured on the spindle o and taking behind a projection R on a
sliding bar or plate S which is drawn constantly to the left in the figure by
means of a spring T, U is a partition in the box P, and V is a false bottom fitted
to slide easily up and down in the box and normally pressed upwards by the
spring W. XX are packets of paper preferably folded to a width of say 1 to

page_text: 2 inches, Y is a slot at the side of the box P of a size suitable for allowing the
end of one of these packets to be pushed outwards as shown at Z in dotted lines
in the figure. S¹ is a downwardly projecting part or spur of the bar or plate S
just long enough to catch behind the rear end of the uppermost of the packets X.
It will now be understood that when the spindle 0 of the lock handle is turned
in the direction of the arrow in order to draw back the lock bolt the bar or
plate S will be drawn forward against the action of the spring and with it the
top most packet of paper so that the end of the latter protrude through the
slot Y into a position where it can be readily got hold of and be drawn out by
the occupant of the closet. On the lock handle being released and turned back
by its follower spring the spring T draws back the bar or plate S into the position
shown in the figure ready for the next operation.
Instead of emploving a sliding bar or plate S with a spur S¹ acting upon the
rear end of the packet of paper the arm Q may be provided with a device in the
nature of a spring-urged or other claw or pointed peg which digs into any
suitable part of the packet of paper next the partition U and moves the said
nacket outwards whenever the spindle o is turned. If desired the paper may
be prepared with a hole or slot in it for the aforesaid claw or peg to take into.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
'
First. The device for indicating, whether the bolt of a door is fastened or not,
which consists of an index operated by the bolt so as to point to words or marks
on a dial or the like indicating and corresponding to the actual position of the
bolt, substantially as described with reference to Figure 1 of the drawings.
Second. In coin-receiving lock mechanism the device for indicating whether
the lock is secure against being opened from the outside, and the indicator
slide for indicating whether the closet, lavatory or the like is "vacant" or
engaged and for opening and closing the coin-slot combined and operating
substantially as described with reference to Figure 2 of the drawings.
Third. In coin-receiving lock mechanism the device for indicating whether
the lock is secure against being opened from the outside, a sliding plate for
opening and closing the coin-slot and a pin on the latch-bolt commanding the
index of the indicating device, combined and operating substantially as described
with reference to Figures 3, 4 and 5 of the drawings.
Fourth. In connection with a lock or fastening for lavatory or the like the
device for delivering paper or the like by the act of turning the handle of the
lock which consists of a box containing the papers a partition in the box for
the papers to be pressed against, a spring actuated false bottom pressing the
papers against the said partition, a slot in the side of the box for the delivery
of the papers, and means actuated by the handle of the lock for pushing out the
paper at each operation of said handle, substantially as described.
