I WILLIAM WADE of Woodhouse Cliff, Leeds in the County of York do hereby
declare the nature of my Invention for AN IMPROVED SELF-ADJUSTING SASH
FASTENER," to bo as follows:-
:-
The object of my invention is to construct a simple and efficient self-adjusting
sash fastener.
I attach a plate to the lower part of the top sash, a projecting stud stands out
therefrom, and. is held in position by a spring the stud when in position prevents
the bottom sash, from being lifted up, and the top sash from being put down
without depressing the stud from the insido, no knife or other instrument being
able to unfasten the window from the outside, it is thus burglar proof.

COMPLETE SPECIFICATION.
5. I WILLIAM WADE of Woodhouse Cliff Leeds in the County of York do hereby
declare the nature of my said Invention for "AN IMPROVED SELF ADJUSTING
SASH FASTENER," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of my invention is to construct a simple and efficient self adjusting
0 sash fastener, by which it is impossible to leave any window unfastoned if closed,
as the act of closing fastens the window,

page_text: Fig 1 is a general view of sash fastener on sash frames.
Fig 2. is an end elevation with sash frames in section, sash secured.
Fig 3 is an end elevation with bottom sash partly raised shewing bolt or stud in
contact with incline.
Fig shews bolt or stud depressed by incline.
Fig 5 is a front elevation of fastener shewing bolt held back by slide or catch.
Fig 6 is a plan of inside of fastener showing spring.
Fig 7, is a back elevation shewing spring.
A is the top sash bar, B is the bottom sash bar, I attach my fastener to the top
sash bar A, and to the bottom sash B I attach an incline or slide piece C. D is
the frame or case of my fastener in which is a bolt or stud E which stands out
therefrom and is held forwards in position over the bottom sash by a spring F,
when it is held forwards the bottom sash cannot possibly be raised, or the top sash
lowered without first pushing back the stud E, and this can only be done from
inside. After the stud is pushed back, and as it clears the incline or slide, it is
moved forwards into position by the spring F and so upon the windows or sashes
being closed it comes in contact with and is depressed by the incline or slide
piece G, as shewn in (Figs 3 and 4) For convenience when cleaning the windows
a slide H may be used for holding the stud back (see Fig 5) whilst the windows
are being moved into the various positions required, the slide H is also very useful
when opening large windows, where the use of both hands are required for raising
or lowering the sashes, fasteners constructed as above are Burglar proof, that is,
cannot be slipped or opened from outside by knife or other appliance, they are
simple of construction and of great durability.
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 The use and employment of the slud E held forwards in position by a spring
such as F (or spring of any other shape or form) as shewn and described.
2 The incline or slide piece C placed between the sashes, and operating upon
the spring, stud or bolt as shewn and described.
3 in the sash fastener herein before described the use of the slide H for holding
the stud in position when depressed as shown and described.
Dated this third day or October 10DT.
