PROVISIONAL SPECIFICATION.
A New or Improved Fastener for Window Sashes, Window
Casements, Shutters, Doors, and for other like Purposes.
I, HARRY SMITH, of 18 and 19, Hockley Hill, Birmingham, Warwickshire,
General Ironmonger and Iron Founder, do hereby declare the nature of this
invention to be as follows:-
This invention consists in the herein described improved fastener for window sashes,
window casements, shutters, doors, and for other like purposes which is constructed
as follows I will describe my invention as used for securing window sashes. In
carrying out my invention I provide a hooked lever-catch which is pivoted at one
end to a plate or base fixed by preference to the top rail of the bottom sash so that
the said lever-catch can be turned in a horizontal plane for its free end to engage
with a pin, projection, or recess on a plate fixed to the lower rail of the bottom
sash. When this lever-catch is moved in one direction its free end engages with
the said pin, projection, or recess on the bottom rail of the top sash and draws the
two sashes together and when the lever-catch is turned far enough in the opposite
direction it allows the sashes to pass and repass each other. This lever-catch is
operated by a lever which may be of a bell crank form one arm of the lever having
a pin engaging in a slot at the back of the lever-catch and the other arm of the
lever being furnished with the usual knob for operating the fastening. This operating
lever turns on a fulcrum pin fixed to the said plate on which the lever-catch is
pivoted.
When the said operating lever is turned in one direction its arm, acting in the slot
at the back of the lever-catch, moves the lever-catch forward so that its free end
will engage with the said pin projection or recess of the part on the lower sash and
pull the sashes together and prevent the sashes being opened; a suitable spring acts
upon a heel on the said operating lever and maintains the operating lever in this
position. The fastener is now closed and it cannot be opened by any pressure on
the lever-catch as such pressure would have a tendency to move the operating lever
in the wrong direction which is prevented by its coming in contact with one end of
the said slot. On turning the operating lever in the opposite direction the lever-
catch is drawn away from the said pin on the lower sash rail and the said spring
acting upon the said heel on the operating lever causes the operating lever to fly
outwardly and to draw the lever-catch into its unlocked position and to maintain it
there so as to allow the sashes to pass and repass each other.
My invention as above described can be similarly applied to casement windows,
shutters, doors, and for other like purposes, and either made to screw on the outside
thereof as above described, or be let in flush with the face of the casement, shutter,
or door, or it can be morticed into the edge of the window, shutter, or door; in this
latter case the operating lever is made with a single arm to engage with the hooked
catch and is operated by being fixed on an ordinary square or other handle spindle
which takes the place of its said fulcrum pin.

A New or Improved Fastener for Window Sashes, Window
Casements, Shutters, Doors, and for other like Purposes.
I, HARRY SMITH, of 18 and 19, Hockley Hill, Birmingham, Warwickshire,
General Ironmonger and Iron Founder, 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 herein described improved fastener for window sashes,
window casements, shutters, doors, and for other like purposes which is constructed
as follows:-
I will describe my invention as used for securing window sashes and will refer to
the accompanying drawings on which Fig. 1 is a plan and Fig. 2 an elevation of a
window sash fastener constructed according to this invention; Figs. 3 and 4 are plans
of the same with the upper plate removed so as to shew the internal mechanism.
The window sash fastener is represented as fastened in Fig. 3 and unfastened in
Fig. 4. Figs. 5 and 6 represent details of the same separately.
The same letters of reference indicate the same parts in all the Figures of the
drawing.
'
In carrying out my invention I provide a hooked lever-catch a which is pivoted at
one end at 6 to a plate or base c fixed by preference to the top rail of the bottom sash
so that the lever-catch a can be turned in a horizontal plane for its free end to engage
with a pin d, projection or recess on a plate e fixed to the lower rail of the bottom
sash. When this lever-catch a is moved in one direction (see Figs. 1, 2 and 3) its
free end engages with the pin d or other projection, or a recess on the bottom rail
of the top sash and draws the two sashes together and when the lever-catch is turned
far enough in the opposite direction (see Fig. 4) it allows the sashes to pass and
repass each other. This lever-catch a is operated by a lever ff¹ which may be and
by preference is of a bell crank form as shewn one arm f of this lever having a pin g
engaging in a slot at the back of the lever-catch a and the other arm f¹ of the lever
being furnished with the usual knob i for operating the fastening. This operating lever
turns on a fulcrum pinj fixed to the plate c on which the lever-catch a is pivoted.
When the operating lever ff is turned in one direction (see Figs. 1, 2 and 3)
its arm fracting in the slot h at the back of the lever-catch a, moves the lever-catch a
forward so that its free end will engage with the pin d or other projection or a
recess of the plate e on the lower sash and pull the sashes together and prevent the
sashes being opened.; a spring k acts upon a heel 7 on the operating lever ff and
maintains the operating lever in this position. The fastener is now closed and it
cannot be opened by any pressure on the lever-catch a as such pressure would have a
tendency to move the operating lever ff in the wrong direction which is prevented
by its coming in contact with one end of the slot h. On turning the operating lever fƒ
in the opposite direction (see Fig. 4) the lever-catch a is drawn away from the pin d
on the lower sash rail and the spring & acting upon the heel 1 on the operating lever
causes the operating lever to fly outwardly and to draw the lever-catch a into its
unlocked position.and to maintain it there so as to allow the sashes to pass and repass
each other.
k
My invention as above described can be similarly applied to casement windows,
shutters, doors, and for other like purposes, and either made to screw on the outside
thereof as above described, or be let in flush with the face of the casement, shutter
or door, or it can be morticed. into the edge of the window, shutter, or
door; in this latter case the operating lever is made with a single arm f to engage
with the hooked catch a and the arm f' is dispensed with and the lever fis operated
by being fixed on an ordinary square or other handle spindle which takes the place
of its fulcrum pin j. When the fastening is used borizontally as on a window sash
as above described, the use of a spring for acting upon the lever ƒ ƒ¹ may be
dispensed with.

page_text: The accompanying drawings illustrate what I consider to be the best way for
carrying my said invention into practice but it is to be understood that my said
invention is not limited to the precise details shewn.
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 window sashes, window casements, shutters, doors and for
other like purposes the combination with the lever-catch a pivotted to one part of the
fastener and adapted to engage with a pin projection or recess of the other part, of
the lever constructed and arranged to operate with the lever-catch a in the manner
and for the purposes substantially as described, whether the spring k and heel / are
used or not and whether the said lever f is made with or without the arm ƒ¹.
2. The combination and arrangement of parts constituting the improved fastener
for window sashes and for other purposes herein before described and illustrated by
the accompanying drawings.
