Improvements connected with Locks or Fastenings for Writing, Bill.
and other Cases.
I, PETER THOMAS JOHNSON, of 15, Gough Square, City of London, Manufac-
turing Stationer, do hereby declare the nature of this invention to be as follows:-
This invention has for object, a certain improvement in double actioned locks
specially adapted for writing cases, bill cases, and the like with which a strap or
binder is employed.
For the purpose of this invention, I make the hasp plate of the lock (spring or
other) with a slot or recess through which a strap or binder with slotted holes
can be drawn, the slotted holes giving a certain amount of play not possessed by
ordinary round holes, and whereby the strap becomes the better adjusted and
allows for unequal strain when being fastened. The lock proper is set trans-
versely to the strap and hasp, and the hasp has a stud or bolt which passes into
and through the strap slot before entering the bolt hole of the lock. The keyhole
and the operative parts of the lock are arranged on one side beyond the strap with
the keyhole exposed, and the other exposed end or side of the lock face plate
has the spring draw back button, if a spring draw back bolt be provided, other-
wise the button may be a dummy.
By this invention, the lock can be secured by the key after the hasp stud
has been pressed home, and can also be unlocked without affecting the strap or
binder.

I, PETER THOMAS JOHNSON, of 15, Gough Square, City of London, Manufac-
turing Stationer 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 has for object, a certain improvement in double actioned locks
specially adapted for writing cases, bill cases, and the like with which a strap or
binder is emploved.

page_text: For the purpose of this invention, I make the hasp plate of the lock (spring or
other) with a slot or recess through which a strap or binder with slotted holes
can be drawn, the slotted holes giving a certain amount of play not possessed by
ordinary round holes and whereby the strap becomes the better adjusted and
allows for unequal strain when being fastened. The lock proper is set trans-
versely to the strap and hasp, and the hasp has a stud or bolt which passes into
and through the strap slot before entering the bolt hole of the lock. The keyhole
and the operative parts of the lock are arranged on one side beyond the strap with
the keyhole exposed, and the other exposed end or side of the lock face plate
has the spring drawn back button, if a spring draw back bolt be provided.
By this invention, the lock can be secured by the key after the hasp stud
has been pressed home, and can also be unlocked without affecting the strap or
binder.
My invention is shown on the annexed drawings.

Figure
5 shows the hasp plate affixed or in position over the lock of a bill
case with the slotted holed strap passed through the hasp plate to fix the fold
Hlap of the bill case, said lock being sufficiently wide for the opening catch stud
to be exposed from one side, and the keyhole of the lock on the other side, or
in visible balance in the front of the bill case for uniformity and neatness.
A, front of hasp plate which may be engraved with any suitable name or device.
A', back of hasp plate.
B, strap loop at the back upper part. C, hasp proper of sufficient depth as to
be passed through either of the slotted holes D, D, of the strap E to suit the
bulkiness of the bill case F, or of other case, box, or receptacle, over or to which
such a lock is affixed and to which such a strap is bound, a portion of said
hasp C extending rearwardly from the strap E as to enter the catch slot of the
lock G as to be fastened therein by the sliding catch in a well known manner,
such a sliding being operable for opening or releasing the catch by the slide
button H, this being near the edge of the lock on the right hand side of the same,
and the keyhole I on or in the left hand side near the other edge of the lock G,
such edges forming side extensions and away from the side edges of the hasp
plate for the purpose before explained. The lock provides more room and gives
a greater scope for the internal mechanism, so that the parts are thereby available
for extra strength and greater play which ensure a perfectly reliable lock to be
fitted instead of one in which the mechanical parts are cramped and consequently
constantly out of order.
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:-
A widened out or side extended catch and bolt lock having a button on or to
one extended side and a keyhole in the other extended side, both sides projecting
beyond a hasp plate having a back loop or slot for the passage of a strap provided
with slotted holes into and through which the hasp proper can be passed. before
entering the hasp hole in the lock plate, the several parts being arranged in the
manner shown for the purposes specified.
