Complete Specification Accepted, 7th Dec., 1888
I, SAMUEL HURST, of 112 Portland Street, Southport, Architect, in the County of
Lancaster, do hereby declare the nature of this Invention to be as follows:-
It consists in a door or other lock, which is automatically released upon the
insertion of a coin-so that the bolt can be slid back, it is suitable for lavatory and
watercloset and other doors.
It consists of a suitable shoot or guide which conducts the coin to one end of a bar
or lever accurately balanced from near its centre so depressing it and so withdrawing
the other end which interlocks in a suitable manner with the bolt of the lock, thus
allowing it to be slided back; and the door opened. Upon the door being closed the
lock bolt is pressed into the lock and releases the coin which falls into a suitable
receptacle. The balance is prevented from prematurely interlocking with the bolt, by
means of a triangular shaped lever pivoted from the corner one lower corner of which
rests under the locking end of the balance bar or lever and the other projects outside
the lock and presses upon a suitable projection upon the door cheek holding up the
locking end of the lever until the door is completely closed.
To open the lock from inside a suitable projection is provided, by means of which
the interlocking end of the balance bar or lever can be lifted, until the bolt is
withdrawn.

Improvements in Coinfreed Locks or Latches.
I, SAMUEL HURST, of 112 Portland Street, Southport, in the County of Lancaster,
Architect, 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 :-
It consists of a door or other lock, the bolt of which is automatically released upon
the insertion of a coin in a suitable slit, so that it can be slided back and is specially
suitable for lavatory or water closet doors, but is also applicable to other doors. It
consists of a suitable shoot or guide which conducts the coin to one end of a suitable
bar or lever accurately balanced from near its centre, the other end of which in its
normal position interlocks in a suitable manner with the lockbolt. The weight of
the coin depresses the end of the lever, withdrawing the other end and releasing the
lock bolt which can then be slided back. The sliding back of the lockbolt releases
the coin which falls through a suitable slit cut in it, into a suitable_receptacle in the
lower part of the lock case. To allow of the closing of the door I use a triangular
shaped lever pivoted from the corner, the lower arm of which rests under the locking
end of the balance bar or lever, and the other arm of which projects outside the lock
and presses upon a suitable projection upon the door cheek, lifting and holding up
the locking end of the balance lever until the door is competely closed. To open the
door from inside, a suitable projection is provided, by means of which the inter-
locking end of the balance bar or lever can be lifted until the bolt is withdrawn.
In order that the foregoing may be better understood I send herewith a sheet of
Drawings in which:-Figs. 1 and 2 show two views of the lock with the front plate
removed. The coin is dropped into the aperture a and falls down the shoot until it
rests upon the balance bar or lever c pivoted from near its centre c 1 (which is shown
in its normal position in Fig. 1 interlocking with bolt d by means of the slot e,) the
weight of the coin f depresses the lever into the position shown in Fig. 2 releasing
the bolt d and allowing it to be slided into the position shown in Fig. 2, when the
coin falls into the receptacle g. The lever c is automatically raised when the door is
closed by means of the triangular lever one end of which h1 presses against the
projection k upon the striking plate of the lock, and the other end h 2 rests below a
projection upon the lever c. When it is desired to open the door from the inside the
arm 2 of the lever is raised by means of the sliding projection to which a

page_text: suitable handle is fitted inside the door, m and n are stops respectively for the levers h
and c.
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 1
claim is :-
1st. The combined apparatus or lock, substantially as described and shown herein
before and in the accompanying drawing, for the purpose set forth.
Dated this 17th day of October 1888.
