PROVISIONAL SPECIFICATION.
An Improved Window Fastener.
I JOHN WILKINSON 36 Park Road Blackpool Lancashire no occupation do hereby
declare the nature of this invention to be as follows:-
My invention relates to an improved fastener for windows, and it has for its object
to provide a fastener which cannot not only be undone from the outside by an
instrument introduced between the meeting rails of the windows, or by breaking the
glass and thereby unlocking the fastener as is usually done by housebreakers or
burglars, but which will be securely locked and prevent the use of such instruments or
means so that the window cannot be unfastened and the premises he entered.
For the purpose of my invention the apparatus required will consist as follows:-
I require a metal plate similar to those generally used upon the meeting rails
of windows, or more particularly the plate to which is attached the catch or circle.
To this plate I attach and secure a catch or circle of a novel design and construction
the method and application of which I now proceed to describe.
The catch or circle is elongated in form or manner to the usual or ordinary catch or
circle and is intended to fulfil the same purpose, while the other or elongated portion
is made in the form of a case or box.
Within the upper surface or plate of this catch or circle there is in addition a slot
running lengthwise a portion of which passes through the circle part, and the other
portion passes through the case or box.
The whole of what I have so far described may be termed a bracket or fixture.
Within the slot contained in the bracket or fixture and in the upper plate of the
catch or circle thereof there is inserted a small working lever sustained and working
upon a pin or stud secured to the side or sides of the case or box. Upon the upper
portion of this lever one or more finger peices may be applied and used for the purpose
of lowering that end of the lever contained in the case or box, and for olevating the
opposite end of the lever.
When the lever is in its proper working position on of its horizontal ends or
extremities is constructed in such a manner as to form a catch which will rise or fall
with the motion of the lever contained in the slot.
This end of the lever is intended to act as a bar or lock to prevent the large or
ordinary arm or lever from being drawn or forced back from its usual fastened
position.
The extreme end of the lever is rounded or bevilled so that when the large lever
is being brought home to its fastened position immediatly it comes into contact
with the small lever it will cause it to rise-untill it has passed beyond the catch
after which this lever resumes its position and the inner portion of the lever
which is made straight or square retains the large arm or lever in its fastened
position, thus preventing it from being put back to its unfastened position untill
released by the hand operating upon the handle or finger peice of the small lever.
The small lever is also retained in a stationary position untill operated upon by the
hand by means of a spiral or other suitable spring contained in the box previously
mentioned.
A notch or steady pin for keeping the lever in position may be used when desireable.
In addition to what I have hitherto described and for further security, and for the
purpose of locking the windows more effectually I introduce and use a lock con-
structed and applied to the fixture or bracket as follows :-
Running through the case or box and secured to and working therein is a stud or
pin one portion of which contains a worm or thread upon which a peice of metal or a
nut is caused to work when the stud or pin revolves.

page_text: +
The stud or pin may be made to revolve by means of a key which may be removable
or otherwise.
A spring may be used for the purpose of keeping the stud or pin in position when
nescessary..
The key is made to operate upon the end or ends of the stud.
The whole of this is intended to act as a lock for the purpose of locking the fastener
when so required and will operate as I now further describe.
When the small lever is unlocked the nut will occupy one of the spaces on the side
of the small lever, but when the stud is revolved by the use and action of a key the
nut will be brought immediatly under the lower portion of this lever and thus
intercepts the downward action of the small lever at this end when being operated
upon by the hand, and will effectually lock both levers of the window fastener, and
they will be retained in this locked position untill released by the use of the key.
It is intended that this invention may be used in a simple or combined form,
namely In a simple form it is intended merely for the prevention of the use of
instruments between the meeting rails of windows, or in its combined form to prevent
the use of instruments as above mentioned, and also to prevent the fastener from being
unlocked by breaking the glass of the window from the outside whereby the hand may
be inserted and used to operate upon the fastener.
When the lock is not used the bracket or fixture may be constructed to occupy less
space or room in its length.
This apparatus may be made of brass or iron or any other suitable metal or material
requisite for its construction.
The key for the lock may be also made in a variety of forms and shapes consistent
with the size and dimensions of the lock.

COMPLETE SPECIFICATION.
An Improved Window Fastener.
JOHN WILKINSON, 36 Park Road, Blackpool, Lancashire no occupation 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 an improved fastener for windows, and it has for its object,
to provide a fastener which cannot, not only be undone from the outside by an
instrument introduced between the meeting of the sashes, or by breaking the glass
and thereby unlocking the fastener, as is usually done by housebreakers, and burglars,
but which will be securely locked and prevent the use of such instruments, or means,
so that the window cannot be unfastened and the premises be entered. For the
purposes of my invention the apparatus required will consist as follows:-
I require a metal plate similar to those generally used on the meeting rails of
windows, or more particularly the plate to which is attached the catch or circle.
To this plate I attach and secure a catch or circle of a novel design and construction,
the method and application of which I now proceed to describe :-
The catch or circle is elongated in form, one of its ends being shaped and made in a
similar form or manner to the usual or ordinary catch or circle, and is intended to
fulfill the same purpose, while the other or elongated portion is made in the form of a
case or box.
Within the upper surface or plate of this catch or circle, there is in addition a slot
running lengthwise a portion of which passes through the circle part, and the other
portion passes through the case or box.
The whole of what I have so far described may be termed a bracket or fixture
within the slot contained in the bracket or fixture, and in the upper plate of the catch
or circle thereof, there is inserted a small working lever sustained and working upon
a stud or pin secured to the side, or sides of the case or box.

page_text: Upon the upper portion of this lever one or more finger pieces may be applied and
used for the purpose of lowering that end of the lever contained in the case or box,
and for elevating the opposite end of the lever.
When the lever is in its proper working position, one of its horizontal ends or
extremities is constructed in such a manner as to form a catch which will rise or fall
with the motion of the lever contained in the slot. This end of the lever is intended
to act as a bar or lock to prevent the large or ordinary arm or lever from being drawn
or forced back from its usual fastened position.
The extreme end of the lever is rounded or bevelled so that when the large
lever is being brought home to its fastened position immediately it comes into
contact with the small lever it will cause it to rise until it has passed beyond the
catch after which the lever resumes its position and the inner portion of the lever
which is made straight or square retains the large arm or lever in its fastened
position, thus preventing it from being put back to its unfastened position until
released, by the hand operating upon the handle or finger piece of the small lever.
The small lever is also retained in a stationary position until operated upon by the
hand, by means of a spiral, or other suitable spring contained in the box previously
mentioned.
In addition to what I have hitherto described and for further security and for the
purpose of locking the window more effectually I introduce and use a lock con-
structed and applied to the fixture, or bracket as follows:-
Running through the case or box, and secured thereto and working therein is a
stud or pin one portion of which contains a worm or thread upon which a piece of
metal, or a nut is caused to work when the stud or pin revolves. The stud or pin may
be made to revolve by means of a key which may be removable or otherwise.
A spring may be used for the purpose of keeping the stud or pin in position when
necessary.
The key is made to operate upon the end or ends of the stud.
The whole of this is intended to act as a lock for the purpose of locking the fastener
when so required, and will operate as I now further describe :-
When the small lever is unlocked the nut will accupy one of the spaces on the side
of the small lever, but when the stud is revolved by the use and action of a key the
nut will be brought immediately under the lower portion of this lever and thus
intercept the downward action of the small lever at this end, when being operated upon
by the hand, and will effectually lock both levers of the window fastener, and they
will be retained in this locked position until released by the use of the key.
It is intended that this invention may be used in a simple or combined form,
namely, in a simple form it is intended merely for the prevention of the use of
instruments between the meeting rails of the windows, or in its combined form to
prevent the use of instruments as above mentioned and also to prevent the fastener
from being unlocked by breaking the glass of the window from the outside whereby
he hand may be inserted and used to operate apon the fastener. When the lock
s not used the bracket or fixture may be constructed to occupy less space or
oom in its length.
This apparatus may be made of brass or iron, or any other suitable metal or
naterial requisite for its construction. The key for the lock may be made in a variety
f forms and shapes consistent with the size and dimensions of the lock.

page_text: Figure 2 gives a front view of the sash fastener as placed upon the upper sash A
and the lower sash and shews the position of the small lever E with the handle or
finger piece K and also the end of the stud for the lock H with the apperture for the
key P.
Figure 3 is an inverted view shewing the interior of the box or case in the
circle D, also shewing the pin or stud with the spring I for carrying the small
lever E, and also the screwed or threaded stud H having upon it the small nut L
which is intended to work and traverse upon the serowed portion of this stud untill
brought beneath the end of the lever E thereby locking the lever in such a manner
that it cannot be raised or moved.
When the lock is not used the lever E then simply acts to prevent the window
being opened from the outside.
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
First. The lever motion attached and working in a bracket or fixture on the
meeting rail of the lower sashes of windows, and to be used in conjunction with
the bracket or fixture generally used upon the meeting rail of the upper sashes
of windows and which operates as a bar or lock to prevent the windows being
opened by the use of an instrument or instruments inserted for the purpose of
opening the windows from the outside.
Second The lever motion as set forth in first claim to which is further attached
a suitable lock to be locked or unlocked with a key and which in its combined
form is intended to prevent the use of an instrument or instruments inserted
between the meeting rails of window sashes for the purpose of opening such
windows, but also to prevent the fastener being operated upon by breaking the
glass of the window whereby the hand may be inserted and the sash fastenor
unfastened which cannot be accomplished without the use of a key to unlock the lock
and other means consisting of the various parts arranged, constructed, and operating
as described in the specification.
