Railway Clerk do hereby declare the nature of this invention to be as follows:-
"
"
A coin or check is inserted in an aperture at the top of the lock, and is received
onto a lever raising a catch which fits into the main bolt, enabling this bolt to
be shot back into the lock by means of the key-A spring is attached to this
bolt which comes in contact with a registering apparatus, and registers
each time the door is unlocked from the outside-Attached to the catch is a weight
which works on a slide regulating the amount to be paid before the door can be
unlocked.
one
Underneath the main bolt is a second bolt which, immediately the door is opened,
shoots out of the lock, and by means of a spring holds the main bolt in the position
in which it has been left by the key-When the door is again closed, the second bolt
is thrust back into the lock (by coming in contact with the door-casing) and releases
the main bolt again locking the door.
When the door is unlocked from the inside it is so arranged that the handle is
on a sliding system, and at the same time that it opens the door, it depresses
the spring which otherwise would be in communication with the registering
apparatus, and thus no record is taken of the lock having been used from
the inside.
When the main bolt is shot back in the first instance, the coin then passes from
the lever on which it was received behind the main bolt and when the door is
again closed, it falls over an aperture in the lock, thus shewing that the place is
occupied when the door is again opened the coin is released and passes into a
recepticle underneath.
The lock can be attached to Turn Stiles etc.

I, JOHN THOMAS KENWORTHY of 41 Shrewsbury Street Old Trafford, Manchester
in the County of Lancaster Clerk 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 locks, latches, or fastenings such as are used for securing
the doors of closets at railway stations, places of amusement, tramcars, and other uses
where doors are necessary, and the object of this invention is to afford means to
obtain payment for admission or entrance of persons to any such places when securely
locked without the necessity of an attendant being required to be present for the
purpose of unfastening or unlocking said doors, or for receiving payment for
admission.
с
In order more clearly to describe my invention I have annexed hereunto a sheet of
drawings. In the several views therein shown, similar letters refer to similar parts.
Fig. 1. is front view of lock with cover plate removed and as seen from the outside
of chamber when the door is closed and locked. Fig. 2. is view of the same lock as
seen from the inside of chamber when the door is
open. In order to obtain admission
when the door is closed and locked as in Fig. 1. a coin or coins of the required valne
are inserted in the aperture at the top of lock a said coin or coins falling into
a receiver c which is attached to end of lever d: the lever d is pivotted at e and
the weight of the coin or coins in the receiver c raises the catch e which is formed
on lever d out of the notch f on the main bolt 9: the main bolt g cannot be moved
back or the door opened until the catch e is raised out of the notch fand this can
only be effected by the correct weight of coin or coins being inserted in aperture b.
When the bolt g is released from contact with lever d by aforesaid means the door
may be opened from outside by the operation of the handle h and the lever '. As
the door is opened the bolt which has previously been held back by contact with
the door frame u is pressed forward as seen in Fig. 2: by means of the
spring k. The end of spring which has hitherto been kept depressed by the
lug m attached to bolt rises when the bolt ; is moved forward and the end l¹
coming in contact with notch gl. formed on bolt a keeps said bolt within the lock
as shown in Fig. 2. until released by the action of closing the door from inside by
the person admitted which causes the boltj to be pressed back by the door frame u
and held back within the lock a, when the bolt g again shoots forward and locks the
door; the bolt g sliding back acts on the lever c¹ and causes the receiver c to tip out
the coin which falls onto and rests on the bolt ; thus covering the aperture n formed
in lock a this aperture n remains covered until the door is again opened for exit
by means of the handle p, to which is attached the V shaped stud q. When the
handle is pushed back from inside the stud raises the lever d and at the same
time draws back the bolt g. The door being opened releases the bolt j which again
choots forward by the action of the spring and the coin or coins fall through the

page_text: aperture into a receptacle placed within the door: A spring or other suitable con-
trivance closes the door when released from pressure and the lock is again in order
for use as represented in Fig. 1. In order to register the number of persons who
have obtained admission by means of a coin or coins as the regulated price or fee
for entrance I place an indicator s within the lock this indicator is actuated by
the spring t which I attach to bolt g. When the door is unlocked from outside by
the incans herein before described the bolt g sliding back causes the spring t to
move the ratchet wheel u one notch and thus register one in order to prevent the
indicator being moved when the door is opened from inside for exit I cause the spring t
to be withdrawn from said ratchet wheel by means of the stud w which is connected
to the handle p and when said handle is moved back the stud w is also moved back
and thereby depresses the spring t.
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:
In a lock or fastening that is employed for securing the doors of closets at railway
stations and for other uses where doors are necessary a lock that is or may be opened
by means of a coin or coins of the stipulated value being inserted in an aperture in
said lock and in combination therewith an indicator for registering the number of
persons who may have thus obtained admission substantially in the manner and for the
purpose as herein before described.
