JOSEPH DEDDEN 3 Cottage Green Southampton Street Camberwell Surrey Tassell
Manufacturer do hereby declare the nature of this invention to be as follows:-
My Invention relates to Window Sash Fasteners and consists of a novel con-
struction fixed on that part of an ordinary Window Sash Fastener which is fixed on
the bottom Window Sash. Various contrivances have already been adopted for
securing Window Sashes but most of them have been too costly or complicated for
general use and all of them have failed to supply the want of a thoroughly good and
reliable means for properly & securely fastening Window Sashes.
I provide a cheap simple and above all an effective device which will afford the
means for effecting a perfectly safe and secure sash fastener.
According to the said Invention I construct a spring which I attach together
with a screw and a catch on that part of an ordinary Sash Fastener which is
fixed on the bottom sash of a Window. When the Sashes are fastened the screw
is turned this fixing the spring and catch preventing the fastening from being
turned back either from the inside or outside of the Window until the screw is
again turned when on this being done and on the screw being pressed the Fastener
can be moved at will Burgalaries often are committed by Burglars inserting between
Window Sashes a knife or some other flat instrument and forcing back the fastener.
This could not be accomplished with my invention in use as the fastener could not
come past the catch without the screw being first pressed. It will be obvious that
this simple means of constructing a sash fastener will render them cheap and practical.
My Invention can be applied to any ordinary Sash Fastener.

page_text: I JOSEPH DEDDEN of No. 3 Cottage Green Southampton Street Camberwell in
the County of Surrey Tassell Manufacturer 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 :-
My Invention relates to Window Sash Fasteners and consists of a novel construction
fixed on that part of an ordinary Window Sash Fastener which is fixed on the bottom
Window Sash. Various contrivances have already been adopted for securing Window
Sashes but most of them have been too costly or complicated for general use and all
of them have failed to supply the want of a thoroughly good and reliable means for
securely and properly fastening Window Sashes. I provide a cheap simple and above
all an effective device which will afford the means for effecting a perfectly safe and
secure sash fastener.
According to the said Invention I construct a spring (marked "A" in the drawing
herewith) which I attach, with a screw, (marked "B" in the drawing herewith) and
a catch, (marked "C" in the drawing herewith) on that part of an ordinary sash
fastener which is fixed on the bottom sash of a Window. When the sashes are
fastened the screw ("B" in drawing) is turned this fixing the spring ("A" in drawing)
and forcing the catch ("C" in drawing) up this preventing the fastening from being
pushed back either from the inside or outside of the window until the screw ("B") is
again turned when on this being done and on the screw ("B") being pressed the
fastener can be moved at will. The screw ("B") being turned is altogether an extra
safeguard as even when the sashes are fastened the fastener cannot even then be forced
back until the Catch ("C") is first pressed down which can be done by pressing the
said screw ("B"). The Window fastens in the ordinary manner the fastener passing
over the Catch ("C") which it presses down but which flies up again when the
fastener has passed over it and prevents the fastener being turned back until the
screw ("B") is first pressed. Burglaries often are committed by burglars inserting
between Window Sashes a knife or some other flat instrument and forcing back the
fastener. This could not be accomplished with my invention in use as the fastener
could not come past the catch ("C") without the screw (B) being first pressed. It
will be obvious that this simple means of constructing a sash fastener will render them
cheap and practicable. My Invention can be applied to any ordinary Sash Fastener.

page_text: 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. That my Invention is simpler and quite as secure as any at present in the
market.
2. That its simplicity will enable it to be supplied to the public at a very cheap rate.
3. That it can be applied to any ordinary Sash Fastener. The drawing sent
herewith completely describes my said Invention and the working thereof.
