page_text: I, GODFREY ROBERT SEALE, of Queen's Hotel, Neath, Glamorganshire, Innkeeper,
do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved self-locking sash fastener, the object of
which is to preclude the possibility of the window being opened from the outside
by means of a knife or other instrument.
For the purpose of this invention an ordinary sash fastener is employed, having
a spring quadrant-movement catch fixed to the out-side sash, and a receiving hasp
fixed to the inner sash. In a space formed beneath the hasp on the inner sash is
mounted a spring on which is formed a tongue. This tongue protrudes through a
slot formed in the bed plate of the said hasp. The tongue is made with a rounded
shoulder on one of its upper edges, so that when the window catch is pressed home
the tongue is depressed in the slot, and rises to its original position by the action
of the spring underneath, after the catch has passed into the hasp, thereby locking
the catch within the hasp. The sashes are now secured, and cannot be opened in any
way from the outside.
In order that the sashes may be opened from the inside, a small pillar is formed
on the spring on which the locking tongue is mounted, this pillar passes through a
hole made for the purpose in the bed-plate of the hasp and has a button formed
on the top, to release the window-catch this button is pressed down with the finger,
depressing the spring underneath, and causing the locking tongue to sink in its
slot, and then the catch may be turned back in the usual way.

I, GODFREY ROBERT SEALE, of Queen's Hotel, Neath, Glamorganshire, Innkeeper, -
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 an improved self-locking sash fastener, the object of
which is to preclude the possibility of the window being opened from the outside
by means of a knife or other instrument.
For the purpose of this invention an ordinary sash fastener is employed, having
a spring quadrant-movement catch fixed to the out-side sash, and a receiving hasp
fixed to the inner sash. In a space formed beneath the hasp on the inner sash is

page_text: mounted a spring on which is formed a tongue. This tongue protrudes through a
slot formed in the bed plate of the said hasp. The tongue is made with a rounded
shoulder on one of its upper edges, so that when the window catch is pressed home
the tongue is depressed in the slot, and rises to its original position by the action
of the spring underneath, after the catch has passed into the hasp, thereby locking
the catch within the hasp. The sashes are now secured, and cannot be opened in
any way from the outside.
In order that the sashes may be opened from the inside, a small pillar is formed
on the spring on which the locking tongue is mounted, this pillar passes through
a hole made for the purpose in the bed-plate of the hasp and has a button formed
on the top, to release the window catch; this button is pressed down with the
finger, depressing the spring underneath, and causing the locking tongue to sink
in its slot, and then the catch may be turned back in the usual way.
Referring to the accompanying sheet of illustrative drawings, Fig. 1 is an
elevation of a sash fastener constructed according to this invention and Fig. 2 is
a plan thereof.
Upon the outer sash a is pivoted the operating lever b similar to that of an ordinary
sash fastener. The lever 6 is preferably fitted with a square portion c adjacent to
the pivot b and a spring d engaging therewith so as to act as a spring catch to
retain the lever 6 in either extreme position.
Upon the inner sash a¹ a hasp e is fitted and a space is formed beneath it in
which a spring f is mounted. A tongue g is mounted on the spring f and pro-
trudes through a slot formed in the base plate of the hasp e. The tongue g is made
with a rounded shoulder as shown so that when the operating lever b is brought
round into the fastening position the tongue g is pressed in the slot until the lever b
is past when it riscs under the action of the spring f thereby locking the lever b
within the hasp e.
In order to release the lever b when required a pin. h provided with an operating
button is fitted to the spring f so as to project up through a hole made for the
purpose in the base plate of the hasp e. On pressing this button i the spring f
and consequently the tongue g is depressed and the lever b can be moved out of
engagement with the hasp e.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
:-
(1) An improved sash fastener comprising an operating lever pivoted on one
sash, a hasp fitted upon the other sash, and under which the said operating lever
engages a spring tongue adapted to retain the said operating lever within the hasp,
and means for depressing the said tongue so as to allow of movement of the operat-
ing lever when required to unfasten the sashes substantially as described.
(2) An improved sash fastener comprising the operating lever b pivotted 61 on
sash a, hasp e fitted upon sash a¹ spring f arranged below the hasp e and provided
with tongue g, and the button i by means of which the tongue 9 is depressed, the
whole arranged constructed and operating substantially as described.
(3) An improved sash fastener substantially as described with reference to the
accompanying drawings.
