Improvements in Window Fastenings.
JOHN STABLES Grocer 482 Stockport Road Manchester Lancashire do hereby
declare the nature of this invention to be as follows:-
:-
This is a self acting window bolt fastener this bolt is let in and fixed into the
sash frame of a window and when fixed a hole is made in the pully style for
the bolt to go into this holt is self acting by being worked with a spring the spring
and bolt is so arranged with a pully at the end of the bolt so that when drawn
back with the key or other suitable contrivance the pully will work up and down.
the pully style when the window or sash frame is pushed up or pulled down this bolt
being self acting it is impossible to leave the window unfastened when closed, it
also allows for ventilation both top and bottom of the window if required and by
using this self acting bolt with the key it forms a lock bolt and without key or
something of the kind it is impossible without breaking the sash to open the
window it is equally secure when open top and bottom for ventilation.

Improvements in Window Fastenings.
I, JOHN STABLES, of 482, Stockport Road, Manchester, in the County of
Lancaster, Grocer, 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 a self acting window fastener which is let into the
sash frame of the window and adapted to engage selfactingly in holes or recesses
formed in the pulley style when it is desired to secure the window in position and
which fastener can be withdrawn from the said holes or recesses by means of a key
or other suitable appliance when it is desired to raise or lower the window.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a longitudinal section and Fig. 2 an end view of my improved window
fastener, Fig. 3 is a front view partly in section and Fig. 4 a plan in section at a
reduced scale showing the same applied to a window.
In carrying out my invention and referring to the figures generally my improved
window fastener consists of a bolt a under the influence of a spiral spring b
carrying at its outer end a pulley c and adapted to slide in a casing d which is let
into the sash frame A, see Figs. 3 & 4. The spring 6 has the tendency of forcing
the pulley end of the bolt a into holes or recesses e formed in the pulley style B
when meeting with the same and thus selfactingly lock the window in position.
When it is desired to raise or lower the window the bolt a is withdrawn by means
of a key f, see Fig. 1, adapted to engage the bolt a.
It will thus be readily seen that it is impossible to leave the window unfastened
either open or closed and that the window may be opened both top and bottom
and locked in position for the purpose of ventilation.

page_text: When the key f is removed it is impossible to open or move the window without
first breaking the sash frame. The bolt a is controlled in its longitudinal
movement by means of a pin g fixed to the same and sliding in a slot h formed in
the casing d.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim, is-
A window fastener, consisting of a bolt a arranged to slide under the influence
of a spring b in a casing d let into the sash frame A in connection with holes or
recesses e formed in the pulley style B, the said bolt being adapted to selfactingly
shoot into the holes or recesses e when opposite thereto and thereby lock the
window securely in position, whilst on withdrawing the bolt the window may be
raised or lowered all substantially as set forth.
