PROVISIONAL SPECIFICATION.
An Improved Fastener for Securing Window Sashes, French
Windows, Doors, and for other like purposes.
I, ROBERT TOLLADAY, of 160, Moseley Street, in the City of Birmingham,
Brassfounder, do hereby declare the nature of this invention to be as follows:-
This invention consists of the herein described improved fastener for securing
window sashes, French windows, doors and other like purposes.
I will describe my invention in connection with window sashes.
One part of the fastener, which is fixed to the bottom rail of the top sash,
consists of a base plate having jointed thereto a lever arm which can be turned
outwardly in a horizontal direction in the usual way over the other part of the
fastening which is fixed to the top rail of the bottom sash. The said lever arm
turns on a fulcrum pin arranged in a box on the said base plate this box containing
a coiled spring like a small clock spring one end of which engages with the fulcrum
of the lever arm and the other end engages with the said box so that this spring
has a tendency to keep the lever arm in its unlocked position parallel with the
sash bars, and when the lever arm has been turned across the bottom sash and is
released the spring will cause the lever arm to fly back to its normal position.
The other part of the fastening, which is fixed to the top rail of the bottom sash,
consists of a plate having jointed to its upper side a catch piece which is pressed
upwardly by a spring and is made with a notch to engage with the lever arm
when the latter is turned across the sashes. The outer end of this catch piece
is suitably formed to be pressed down by the thumb or finger to release the
lever arm.
The fastening above described acts as follows:-When the lever arm is turned
against the spring across the bottom sash, the lever arm presses the catch piece
downwardly until the lever arm arrives at the notch in the catch piece when the
latter is by its spring moved upwardly and thus engaged with the lever arm holding
the same in its locked position.
To release the lever arm, it is only necessary to press down the catch piece far
enough when the said coiled spring in the spring box will cause the lever arm to
turn and fly back in its normal position parallel with the sashes.
'The fulcrum pin of the lever arm is by preference arranged to turn in a
bearing in the top and in the bottom of the spring box and made square where
it passes through the spring and through the lever arm so
as to engage
with both.
The lever arm may have a rebate near its outer end to press against the catch
piece as the lever is turned into its closed position and thus draw the sashes
together.
My invention is constructed as a fastener for securing French windows, doors
and for other like purposes similarly as above described with reference to window
sashes and is applied to the said French windows, doors and other purposes in the
same ways as are other lever fasteners.

Windows, Doors, and for other like purposes.
I, ROBERT TOLLADAT, of 160, Moseley Street, in the City of Birmingham,
Brassfounder, 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 of the herein described improved fastener for securing
window sashes, French windows, doors and other like purposes.
I will describe my invention in connection with window sashes and refer to the
accompanying drawings on which
Fig. 1 is plan of a window sash fastener constructed according to this
invention; Fig. 2 is a front elevation of the same; in these figs. the sash fastener
is shewn unfastened;
Fig. 3 is a plan of the said fastener fastened and Fig. 4 shews a part of the same
separately;
Fig. 5 is a plan of a modified form of the said sash fastener and Fig. 6 is a side
elevation of one part of the fastener shewn by Fig. 5.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawings.
Referring firstly more particularly to Figs. 1 to 4 both inclusive, one part of the
fastener, which is fixed to the bottom rail of the top sash, consists of a base plate A
having jointed thereto the lever arm B which can be turned outwardly in a
borizontal direction in the usual way over the other part C of the fastener which
is fixed to the top rail of the bottom sash. The lever arm B turns on or with a
fulcrum pin D arranged in a box a¹ on the base plate A this box containing a
coiled spring E preferably like a small clock spring or the spring may be made
of coiled wire, one edge e of which engages with the fulcrum pin D of the lever
arm B and the other end e engages with the box a¹ so that this spring has a
tendency to keep the lever arm in its unfastened position shewn in Figs. 1 and 2
parallel with the sash bars; and when the lever arm B has been turned across the
bottom sash to the position shewn in Fig. 3 and is released, the spring E will
cause the lever arm B to fly back to its normal position shewn in Figs. 1 and 2.
The other part of the fastening, which is fixed to the top rail of the bottom sash,
consists of a plate C having jointed to its upper side a catch piece F which is
pressed outwardly by the spring g and is made with a notch f¹ to engage with the
part b' of the lever arm B when the latter is turned across the sash as shewn in
Fig. 3. The outer end 2 of the catch piece F is suitably formed to be pressed
by the thumb or finger to release the lever arm B. f3 is a fulcrum pin on which
the catch piece F turns, this pin being carried by the usual quadrant like plate H
and the base plate C between which the catch piece F is situated.
The fastener above described acts as follows:-When the lever arm B is turned
against the pressure of the spring E across the part of the fastening which is fixed
to the bottom sash, the lever arm B presses the catch piece F inwardly until the
lever arm arrives at the notch f¹ in the catch piece when the latter is by its
spring g moved outwardly and thus engages with the lever arm as shewn in Fig. 3
holding the same in its locked position.
To release the lever arm B it is only necessary to press back the catch piece F
far enough for the notch f¹ to be free of the part 6 of the lever B when the
coiled spring E in the spring box a¹ will cause the lever arin B to turn

page_text: and fly back to its normal position shewn by Figs. 1 and 2 parallel with
the sashes.
The fulcrum pin D of the lever arm B is by preference arranged to turn in
a bearing in the top plate a and in the bottom plate A of the spring box a¹
and is made square where it passes through the spring E and through the lever
arm B so as to engage with both. The part 6 of the lever arm B in addition
to engaging with the catch piece F acts against the quadrant piece H in the
usual way when the lever is turned into its closed position and draws the sashes
together.
In the modification of my invention shewn by Figs. 5 and 6, the catch piece F,
instead of being arranged to move in a plane parallel with the plane in which the
lever arm B turns is jointed at one end to the base plate C and is arranged to
move up or down in a plane at right angles to the plane in which the lever arm B
works, so that when this lever arm is turned across the part C as above described
and shewn in Fig. 5, the catch piece F will spring outwardly and the notch of the
catch piece will engage with the lever arm B and retain the same locked in this
position from which it can be released by pressing down the outer end f* of the
catch piece F.
My invention is constructed as a fastener for French windows doors and for other
like purposes similarly as above described with reference to window sashes and is
applied to the said French windows doors and other purposes in the same ways as
are other lever fasteners.
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
1. In a fastener for securing window sashes, French windows, doors and for
other like purposes the combination of the lever arm B jointed at one end to the
base A and provided with a coiled spring at its fulcrum end arranged to turn the
lever back to its unfastened position, and the base C of the other part of the fastener
provided with a spring catch F adapted to retain the lever in its fastened position
across the fastener, and when the outer end of the said spring catch is pressed the
lever will be released and spring back in its unfastened position, all substantially as
described.
2. The combination and arrangement of parts forming the improved fastener for
window sashes French windows doors and for other like purposes, hereinbefore
described and illustrated by Figs. 1 to 4 of the accompanying drawings.
3. The combination and arrangement of parts forming the improved fastener for
window sashes French windows doors and for other like purposes, herein before
described and illustrated by Figs. 5 and 6 of the accompanying drawings.
