PROVISIONAL SPECIFICATION.
Improvements in the Construction of Fastenings for Automatically
Securing Windows, Casements, Doors, and the like.
GEORGE THOMAS DIGGENS 76 Derby Road Nichols Town Southampton, Hants,
Draper do hereby declare the nature of this invention to be as follows:-
These improvements consist of a box or case of any desirable shape open at one end
having a slot through which a pin may slide and a hole for a screw or rivet upon
which the box or case may turn. Into the box or case a bolt is fitted also having a
slot through it to ensure it's sliding on the pivot passing through it and the case.
The bolt is kept towards the open end of the case by a suitable spring, the screw
rivet or other dovice passed through the slot in the case into the bolt forming a
thumb or catchpiece whereby the bolt can be drawn within the case. This case has at
it's opposite end a lug fitted to engage a staple clip or other fastening, having an arc
or wedge shaped side to draw or bind the sash, or the like. The case carrying the
sliding bolt is pivoted upon a plate having a box or staple into which the bolt on being
brought round to a suitable position is forced by the spring in the case acting upon it
and automatically locking it. A lug on the staple prevents the bolt from being shot
until it has been brought into the proper position for locking.

COMPLETE SPECIFICATION.
Improvements in the Construction of Fastenings for Automatically
Securing Windows, Casements, Doors, and the like.
I GEORGE THOMAS DIGGENS, of 76 Dorby Road, Nichols Town, in the Town of
Southampton, in the County of Hampshire, Draper, 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 :-
I construct of some kind of metal, a fastener, which on being brought round to a
suitable position automatically locks itself.
These improvements, consist of a box A or case, of any desirable shape open at one
end, having a slot I through which a pin or pivot G may slide and a hole for a pin
screw or rivet G upon which the box or case may turn.
Into the box A or case a bolt L is fitted also having a slot I, to allow its sliding on
the pivot G passing through it and the case.
The bolt is kept towards the open end of the case A, by a suitable spring C.
The serow pivot or other device D passed through the slot 1 in the case A into the
bolt L forming a thumb or catchpiece whereby the bolt L can be drawn within the
case A.
The case A has at its opposite end a lug, nob, or other device E fitted to engage a
staple clip H or other fastening having an arc wedge or other shape side to draw
or bind the sash or the like.
A point M screw top or other device fitted to the top of pin G keeps box in
position.
The box or case A works upon a pin scrow or rivet G on a plate J having a box or
staple F into which the bolt L in the box or case A on being brought round to a
suitable position is forced by the spring O in the case A acting upon it and automatically
locking the fastener.
A lug B at the side of staple F prevents the bolt L being shot until it has been
brought into the proper position for locking.
Fig. 2 represents the lug or clip for drawing or binding the sash or the like.

Fig. 4 represents the bolt with end K which fits into spring (and slot I in which
pin can slide.
Fig. 5 section D pin acting upon bolt and arrow for direction of pressure to unlock
fastener, bolt A, pivot G, cap F, spring O.
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
1st. The case with spring & slotted bolt inside.
2nd. The staple or box with lug on plate to receive bolt making an automatic lock
fastener preventing the same being tampered with from the outside.
Dacco this 24th day of September 1900.
