PROVISIONAL SPECIFICATION.
Improvements in Registering Locks.
I WILLIAM BARTHOLOMEW, of the firm of B. Finch & Co. of 82 Belvedere
Road, Lambeth, in the County of Surrey, Sanitary Engineer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements in registering locks, and particularly to
such as are used for registering the number of persons using a water closet, with
the object of giving to the attendant free access to the closet when required without
alteration of the register, the counter only registering when the occupant of the
closet makes his exit therefrom.
The mechanism or device which I use for this purpose consists of two levers
combined with the locking and registering apparatus in such a manner that one is
operated only by the action of the key while the other can only be actuated by the
handle within the closet, the key only commencing the registration which is
completed by the action of the handle, and until this action takes place the
attendant using his key being free to enter the closet at will to clean it or to
restore any article accidentally left by the occupant, no registration then taking
place.
For the better comprehension of my invention I will describe it by reference to
the accompanying drawing upon which :-
Figure 1 represents a lock as it appears on the outside of the closet,
Figure 2 same seen from the inside of the closet,
Figure 3 represents the lock with indicating mechanism removed to show the two
levers which operate the registering apparatus or counter,
Figure 4 is a top plan view of my device and of bar J detached showing
teeth, and ratchet wheel L,

inside of the door,

upon by the attendant,
E main bolt of lock,
F follower actuating bolt E. when operated by attendants key, to open
the door,
G follower actuating bolt E when operated on by the handle K to open
the door,
H stops limiting travel of bolt,
I spring, shooting the bolt E,
J bar receiving motion from pin B and transmitting it to the registering
apparatus by the teeth or projections j, j¹ see Figure 4,
K handle to be turned by occupant of closet to obtain exit from same-k spindle
of handle,
L ratchet wheel in connection with pinions actuating registering dials or wheels
indicating the number of persons using the closet,
M. opening for insertion of key.
To enter the closet the attendant inserts his key at M and by turning it moves
the bolt E backward, at the same time turning the lever A. so that striking against

page_text: the pin B it carries it to the position indicated by D Figure 3, the bar J moving
with it and acting on the wheel L so that it shifts to the extent of half a tooth, by
means of the projection j, in which position it will remain even if the attendant
should act again upon the bolt with his key. In this movement the registering
wheel previously indicating say 830 is moved so that the 0 is advanced as shown
Figure 1.
The closet door having been thus opened by the attendant and closed upon the
person using it, when this latter desires to leave he has simply to turn the handle K
(Figure 2) which while drawing back the bolt E, leaving the door open, also causes
the lever C to come against the pin B returning it to its original position carrying
with it the bar J (as shown Figure 4) causing it to advance the wheel L, by the
projection j¹, to the extent of another half tooth, when the indicator which stood
midway between 830 and 831 will show this latter number, and so on for each turn
of key and handle.
I have not shown any particular construction of indicator or counter, as my
device
may be put into connection with various constructions, but that to which
I now give preference is that known as "Harding's Counter" the construction of
which is well known.
I limit the travel of the bolt into the striking plate by the stops H.
It will be seen that by my invention I obviate the necessity of allowing
deductions from the register for entrance of attendant.
Dated this Eighteenth day of March 1892.

Improvements in Registering Looks.
I WILLIAM BARTHOLOMEW, of the firm of B. Finch & Co. of 82 Belvedere
Road, Lambeth, in the County of Surrey, Sanitary Engineer, 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 :-
This invention relates to improvemente in registering locks, and particularly to
such as are used for registering the number of persons using a water closet, with
the object of giving to the attendant free access to the closet when required without
alteration of the register, the counter only registering when the occupant of the
closet makes his exit therefrom.
The mechanism or device which I use for this purpose consists of two levers
combined with the locking and registering apparatus in such a manner that one
is operated only by the action of the key while the other can only be actuated by
the handle within the closet, the key only commencing the registration which is
completed by the action of the handle, and until this action takes place the
attendant using his key being free to enter the closet at will to clean it or to
restore any article accidentally left by the occupant, no registration then taking
place.
For the better comprehension of my invention I will describe it by reference to
the drawing left with the Provisional Specification upon which :-
Figure 1 represents a lock as it appears on the outside of the closet,
Figure 2 same seen from the inside of the closet,
Figure 3 represents the lock with indicating mechanism removed to show the two
levers which operate the registering apparatus or counter,
Figure 4 is a top plan view of my device and of bar J detached showing teeth ;, ;¹
and ratchet wheel L,
Figure 5 the locking mechanism.

page_text: A being the lever
outside of the door,
B a pin on the bar J,
De actuated by the attendant using his key from the
C the lever to be actuated by user of the closet turning the handle from the
inside of the door,
D dotted line indicating position of pin B after the lever A. has been operated
upon by the attendant,
E main bolt of lock,
F follower actuating bolt E when operated by attendant's key, to open
the door,
G follower actuating bolt E when operated on by the handle K to open
the door,
H stops limiting travel of bolt,
I spring, shooting the bolt E,
J bar receiving motion from pin B and transmitting it to the registering
apparatus by the teeth or projections j, j see Figure 4,
K handle to be turned by occupant of closet to obtain exit from same-k spindle
of handle,
L ratchet wheel in connection with pinions actuating registering dials or wheels
indicating the number of persons using the closet,
M opening for insertion of key.
To enter the closet the attendant inserts his key at M and by turning it moves
the bolt E backward, at the same time turning the lever A so that striking against
the pin B it carries it to the position indicated by D Figure 3, the bar J moving
with it and acting on the wheel L so that it shifts to the extent of half a tooth, by
means of the projection j, in which position it will remain even if the attendant
should act again upon the bolt with his key. In this movement the registering
wheel previously indicating say 830 is moved so that the 0 is advanced as shown
Figure 1.
The closet door having been thus opened by the attendant and closed upon the
person using it, when this latter desires to leave he has simply to turn the handle K
(Figure 2) which while drawing back the bolt E leaving the door open, also causes
the lever C to come against the pin B returning it to its original position carrying
with it bar J (as shown Figure 4) causing it to advance the wheel L, by the pro-
jection, to the extent of another half tooth, when the indicator which stood
midway between 830 and 831 will show this latter number, and so on for each turn
of key and handle.
I have not shown any particular construction of indicator or counter, as my
device may be put into connection with various constructions, but that to which
I now give preference is that known as Harding's Counter" the construction of
which is well known.

I limit the travel of the bolt in the striking plate by the stops H.
It will be seen that by my invention I obviate the necessity of allowing
deductions from the register for entrance of attendant.
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. A registering lock in which the turning of a key inserted on one side of the
lock opens the lock and operates a lever simultaneously commencing registration,
in combination with a second lever which when the bolt is drawn from the
opposite side of the lock simultaneously completes the registration, substantially as
hereinbefore described.
2. In a registering lock, the levers A and C arranged to alternately operate the
bar J and wheel L by means of the striking pin B substantially as hereinbefore
described with reference to the drawing left with my Provisional Specification.

page_text: 3. The registering lock hereinbefore described and shown on the drawing herein
referred to, as and for the purpose specified.
