Window-shutters, and for other like Purposes.
We, EDWIN JAMES TONKS, of 56, New Road, Willenhall, Staffordshire, Lock
Manufacturer, and GEORGE BURDEN, of Christ Church Passage, Birmingham,
Warwickshire, Engineer, do hereby declaro the nature of this invention to be as
follows:-
This invention consists in the improved fastener for securing window-sashes,
box-lids, window-shutters and for other like purposes constructed substantially as
hereinafter described the objects of the invention being to provide a secure and reliable
fastener at a low cost.
In carrying out this invention as a window-sash fastener we provide, on the upper
side of the lower sash rail of the upper sash, a plate to which is hinged a hasp or
hoop preferably formed of wire bent into the required shape but which may also be
made from sheet metal or by casting. This plate and hasp can be made very cheaply
by the plate being formed of sheet metal similar to one half of a butt hinge and its
edge bent round one end of the hasp similarly to a hasp for use with a staple for
securing a door by a padlock. The said hasp can be turned on its hinged end so as
to lie across the joint of the two sashes or turned up so as to allow the sashes to
pass and repass each other. On the upper side of the top sash rail of the lower sash
we provide a second plate which may be similar to the first said plate and near the
front edge of this second plate is hinged a lever which when the fastener is closed is
turned down in front of the sash but which can be turned up on its hinge and thrown
back to lie on its said plate. The hinge joint of this lever is thus in front of, but
parallel to, the hinge joint of the hasp. The hasp is made long enough and of such a
width that when it is turned down across the sash rails it will snap on to and embrace
the hinged edge of the second plate, it being pressed down into that position by the
said lever having been previously threaded through the hasp and taking on to its
го

page_text: upper side. This lever has a heel which when the hasp is turned down in position and
the lever is raised engages with the front of the hasp and raises it from the front edge
of the second plate.
The said plates are secured to the sashes by screws as usual.
To fasten the sashes by the fastener above described the lever is thrown back on its
hinge and the hasp turned down on to the second plate as above described. The lever
which is now projecting upwardly through the hasp is turned forward and in its
course engages with the hasp and draws the two sashes together and on finally turning
down the lever in front of the sash it forces down the hasp over the front edge of the
second plate and secures the sashes. To unfasten the sashes, the heel of the lever, on
the lever being turned upwardly, comes into contact with the end of the lasp and
disengages it from the front edge of the second plate and on the lever being thrown
back the lasp is free to be raised and the sashes are unfastened. That part of the said
lever which projects beyond the front of the hasp when the latter is lying on the
second plate is cranked or hent down in front of the sash thus forming a decided
notch in the lever which fits on to the said hasp and prevents the hasp being raised
without first raising the lever which could not be done through the joint of
the sashes.
The fastener above described can similarly be used for securing the lid of a box or
for window-shutters or for other like purposes.

We, EDWIN JAMES TONKS, of 56, New Road, Willenhall, Staffordshire, Lock
Manufacturer, and GEORGE BURDEN, of Christ Church Passage, Birmingham,
Warwickshire, Engineer, 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 consists in the improved fastener for securing window-sashes, box-
lids, window-shutters and for other like purposes constructed substantially as
hereinafter described the objects of the invention being to provide a secure and
reliable fastener at a low cost.
In carrying out this invention as a window-sash fastener we provide, on the upper
side of the lower sash rail of the upper sash, a plate to which is hinged a hasp or loop
preferably formed of wire bent into the required shape but which may also be made
from sheet metal or by casting. This plate and hasp can be made very cheaply by the
plate being formed of sheet metal similar to one half of a butt hinge and its edge bent
round one end of the hasp similarly to a hasp for use with a staple for securing a door
by a padlock. The said hasp can be turned on its hinged end so as to lie across the
joint of the two sashes or turned up so as to allow the sashes to pass and repass each
other. On the upper side of the top sash rail of the lower sash we provide a second
plate which may be similar to the first said plate and near the front edge of this
second plate is hinged a lever which when the fastener is closed is turned down in
front of the sash but which can be turned up on its hinge and thrown back to lie on
its said plate. The hinge joint of this lever is thus in front of, but parallel to,
the hinge joint of the hasp. The hasp is made long enough and of such a width that
when it is turned down across the sash rails it will snap on to and embrace the hinged
edge of the second plate, it being pressed down into that position by the said lever
having been previously threaded through the hasp and taking on to its upper side. This
lever has a heel which when the hasp is turned down in position and the lever is
raised engages with the front of the hasp and raises it from the front edge of the
second plate.
The said plates are secured to the sashes by screws as usual.
To fasten the sashes by the fastener above described the lever is thrown back on its
hinge and the hasp turned down on to the second plate as above described. The lever
which is now projecting upwardly through the hasp is turned forward and in its
course engages with the hasp and draws the two sashes together and on finally turning
down the lever in front of the sash it forces down the hasp over the front edge of the

page_text: second plate and secures the sashes. To unfasten the sashes the heel of the lever, on
the lever being turned upwardly, comes into contact with the end of the hasp and
disengages it from the front edge of the second plate and on the lever being thrown
back the hasp is free to be raised and the sashes are unfastened. That part of the
said lever which projects beyond the front of the hasp when the latter is lying on the
second plate is cranked or bent down in front of the sash thus forming a decided
notch in the lever which fits on to the said hasp and prevents the hasp being raised
without first raising the lever which could not be done through the joints of
the sashes.
The fastener above described can similarly be used for securing the lid of a box or
for window-shutters or for other like purposes.
We will now proceed to describe with reference to the accompanying drawing the
manner in which our invention is to be performed.
Figure 1 represents in side elevation and Fig. 2 in plan a fastener constructed
according to our invention Figs. 3 and 4 illustrate the action of the same; Fig. 5
illustrates in side elevation and Fig. 6 in plan a modification of the same and Figs. 7
and 8 illustrate a further modification of the same.
The same letters of reference indicate the same parts in the several figures of the
drawing.
Referring firstly more particularly to Figs. 1, 2, 3 and 4, a is the hasp or loop, 6 is
the plate to which it is hinged and which is fixed to the upper side of the lower sash
rail c of the upper sash, and d is the lever which is hinged to the plate e which is fixed
to the upper sash rail of the lower sash. In this example of our invention the
hasp a and plate b are similar to a hasp and plate for use with a staple for securing a
door by a padlock except that the hasp is slightly bent at a so as the better to engage
with the plate e as hereinafter described. That part of the hasp which forms the
hinge is prolonged at one side a and turned up at about right angles to the body of
the hasp so as to form a stop and prevent the hasp being turned back too far as shewn
by Fig. 3. The hasp a is made long enough and of such a width that when it is turned
down across the sash rails as shown in Figs. 1 and 2 it will snap on to and embrace
the hinged edge of the second plate e. The lever d has a heel d' which, when the hasp
is turned down in position and the lever d is raised, engages with the front of the hasp
and raises it from the front edge of the plate e.
To fasten the sashes the lever d is thrown back on its hinge as shewn by Fig. 3 and
the hasp is turned down on to the plate e so that the lever d will project upwardly
through the hasp. The lever d is now turned forward and in its course engages with
the hasp a as shewn by Fig. 4 and draws the two sashes together and when the lever d
is turned down as shewn by Fig. 1 it will have drawn the front of the hasp over the
front curved edge of the plate e so that the front of the hasp will snap just below the
projecting hinged part as shewn by Figs. 1 and 2. To unfasten the fastener the lever d
is turned upwardly and its heel d coming into contact with the end of the hasp
disengages the hasp from the front edge of the plate e as shewn by Fig. 4; the basp
is now free to be raised and the sashes are unfastened. The part of the lever which
passes through the hasp a and which projects beyond the front of the hasp when the
latter is lying on the second plate as shewn by Fig. 1. is cranked or bent down in front
so as to form a decided notch which fits on to the lasp a thus preventing the hasp
being raised without first raising the lever thereby securing the hasp from being turned
upwardly through the joint of the sashes.

In the modification illustrated by Figs. 5 and 6 the hasp is made of cast or sheet
metal provided with a hole a³ for the lever d to pass through. In other respects it is
the same as the fastener illustrated by Figs. 1, 2, 3 and 4.
In the modification illustrated by Figs. 7 and 8 the lever d is made with the heel
part d' uppermost and the hasp a is elongated and curved round the heel to engage
in the notch d². By this means the hole a³ in the hasp is dispensed with. The front
end of the hasp engages under the curved edge of the plate e and fastens the
fastener in a similar manner to that herein before described an illustrated by the
preceeding figures.
