ELLEN WILKINSON 36 Park Road Blackpool Lancashire Lady, no occupation, or
calling Ellen Wilkinson do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved window fastener, 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 sashes, 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 will prevent the use of instruments, or other means, so that
the window cannot be unfastened, and the premises entered thereby.
My invention consists of a metal plate, having a catch similar to those generaly used
on the meeting rail of the lower sash of the window, and having a slot running length-
wise, also on the underside of the plate, one, or more plates are attached. Within the
slot it is intended to insert a small working lever sustained and working on a stud, or
pin secured to the plates on the underside of the plate before mentioned.
When the lever is in its proper working position one of its ends forms a handle, or
finger peice for the purpose of raising the lever at this end and thereby depressing the
opposite end of the lever.
This portion of the lever is made to rise in a slopeing, or bevilled form from the
level of plate to the underside of the catch thereon, and is so bevilled in order to allow
the large lever of the ordinary fastener to slide over to its position when locked. This
end of the lever is intended also to act as a bar, or lock to prevent the large, or
ordinary lever from being drawn, or forced back from the usual fastened position.
The lever contained in the plate is retained in a stationary position by means of a
spiral, or other suitable spring which keeps it in its place, untill operated upon by the
hand whereby the larger lever is liberated, and can be used without interuption.
One end of the small lever may rest upon the plate by means of a notch, or a
stoady nin.

page_text: In addition to this, and for further security on one or more of the plates previously
mentioned a lock is constructed in such a manner that when locked with a key the
bolt, or bar of the lock shall intercept, and hold in a fixed position the small lever, thus
effectualy retaining the large lever which works from the upper sash in its fastened
position.
This apparatus may be made of brass or iron, or any suitable metal or material.
This invention may be used in a separate manner, namely as a preventative to the use
of instruments between the sashes, or in a combined form to prevent the fastener from
being unlocked by breaking the glass, or by other means.

ELLEN WILKINSON 36 Park Road Blackpool Lancashire, no occupation. I Ellen
Wilkinson 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 instru-
ment introduced between the meeting of the sashes, or by breaking the glass and thereby
unlocking the fastener as is usualy 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 be entered. For the purposes of my
invention the apparatus required will consist as follow:
I require a metal plate fitted with a catch or circle similar to those used on the
meeting rail of the lower sash of the window, but having in addition a slot running
lengthwise, and also on the underside of the plate are one or more plates, the whole of
which may be termed a bracket, or fixture.
Within the slot contained in the upper plate of the fixture there is inserted a small
working lever sustained and working upon a stud or pin secured to the plate or plates
of the bracket or fixture.
When this lever is in its proper working position one of its horizontal ends, or
extremities forms a handle, or finger peice to be used for the purpose of raiseing the
lever at this end, and thereby depressing or lowering the opposite end of the lever.
This portion of the lever is made to rise in a slopeing, or bevilled form, from or near
the level of the upper plate of the fixture first mentioned to the underside of the catch,
or circle thereon, and is so bevilled in order to allow the large lever or.arm of that part
of the ordinary sash fastener which is used upon the upper sash to slide over to its
position when fastened.
This end of the lever is also intended to act as a bar or lock to prevent the large or
ordinary lever from being drawn or forced back from the usual fastened position.
This lever is also retained in a stationary position by means of a spiral or other
suitable spring, which keeps it in its position untill operated upon by the hand when by
raiseing the handle, or finger peice of the lever the ordinary large lever or arm con-
tained upon the upper sash is liberated an can be used without interuption.
One end of the small lever contained in the fixture is provided with a notch, or
steady pin or other suitable means to keep it in position when at rest.
In addition to what I have hitherto discribed and for further security, upon the
bracket, or fixture first discribed as being fixed upon the lower sash and upon the under-
side thereof a lock is placed in such a manner that when locked with a key the bolt,
or bar, or other locking parts of the lock will intercept and hold in a fixed position the
small lever thus effectualy retaining the larger lever or arm which works from the
upper sash in its fastened position, or in such a manner that both levers are held in a

page_text: fixed position and cannot be moved, or operated untill the smaller lever is released by
unlocking the lock with a key.
The lock may be constructed of any suitable form, or shape capable of being attached
to the bracket, or fixture, or which can be used in conjunction with the small working
lever, and may be locked, or unlocked by means of any suitable or appropriate key,
which the formation of the lock may demand or require.
It is intended that this invention may be used in a simple, or in a combined form,
namely, in a simple form it is intended merely for the prevention of the use of instru-
ments between the meeting-rails of the sashes, or in a 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 sash fastener.
A cover may be used for the lock, and the underwork of the fixtures if required.
This apparatus may be made of brass or iron, or any other suitable material suitable
for its construction.
On the accompanying sheet of drawings I illustrate the application of my invention
to the sashes of windows.
The drawing shews provision for the prevention of the use of instruments introduced
between the meeting rails of the window sashes with the object of forceing back the
fastener from its fastened position, and also shews provision for preventing the sash
fastener from being forced back from its fastened and locked position by breaking the
glass of the window, and thereby gaining access to the fastener. I do not restrict
myself to the form or shape of the lock or key which may be fitted to the lever motion
described in the specification, nor to the details of the construction of this apparatus.
Figure 1. shews part of the sash fastener used upon the meeting rail of the upper
sash of the window.
Figure 2. is a view of the other portion of the sash fastener described as a fixture,
and shews it with the small lever inserted in the upper plate also the spring and the
method of attaching the lever to the fixture.
Figure 3. gives a view shewing the figures 1 and 2. in their position upon the
meeting rails of the sashes, with the small lever as inserted in the upper plate of
fixture upon the lower sash.
Figure 4. is the same as figure 1.
Figure 5 shews the application of a lock in its unlocked position with the small lever,
and spring, and the method of attachment to the plate, or plates contained upon the
fixture upon the lower sash of the window.
Figure 6. is an elevation shewing the inner front of the meeting rails of the sashes
with the fastener mounted in the usual fixed position, and also gives a view of the small
lever and the aperture for the key.
The same letters refer to corresponding points on all the figures.
Figure 1. A is the fixture or bracket with the large arm or lever B as is generaly
used on the upper sash of windows.
Figure 2 is the fixture or bracket C to be used on the lower sash O of window, with
catch or circle D, also the small lever E shewn as inserted in the slot of the upper
plate Fof, fixture C and secured by a pin or stud G to one or more of the plates H of
which I prefer that there should be two plates, although one plate may be deemed
sufficient. This figure also shews the spring I used to keep the small lever E in
position, and also the handle or finger peice K whereby this small lever E may be
raised thus depressing or lowering the end of the lever M in order to allow a free
passage for the large arm or lever B from its fastened position.
When the windows is required to be fastened the large lever B is brought forward
from its position upon the fixture A upon the upper sash as shewn in figures 1 and 4,
and slides over the small bevilled lever E upon the lower sash O thereby depressing
the end of the lever lettered M. and immediatly after the large lever B has passed the
point M the small lever E resumes its position when at rest as shewn in figures 2-5 and 6,
thus effectualy preventing the large lever B from being moved back to its unfastened
position untill the small lever E is opérated upon at the handle K.

page_text: Figure 3. gives a view of figures 1 and 2 in their respective positions upon the upper
sash N and the lower sash O showing the two fixtures A and C with the catch or circle D
and with the large lever or arm B, and also gives an upper view E of the small lever
as inserted in the slot of the upper plate F of the fixture.
Figure 4. illustrates same as figure 1.
Figure 5. presents a view of the fixture C with the small lever E secured as described
in figure 2, also the catch or circle D and the spring I, and this figure also displays
the bolt or bar P of the lock as applied to the small lever motion E, and it will be seen
that when the bar or bolt is shot or moved in the direction of the arrow S the point R
of the bar or bolt P will be brought immediatly under the end of the small lever E
and intercept its downward motion thus iffectualy locking the small lever E and the
large arm or lever B and retains both the levers in their locked position untill unlocked
with the key, and released by the hand at the handle K.
Figure 6. is a front elevation shewing the inner front view of the meeting rails N
and with the fixtures A and C secured thereon and the large arm or lever B in its
fastened position and further secured by the small lever E in its locked position, also
the aperture T for the key.
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 :
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 instru-
ment 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 fastener unfastened, which act cannot be accom-
plished without the use of a key to unlock the lock or by other means.
Consisting of the various parts arranged constructed and operating substantially as
described on the drawing.
