PROVISIONAL SPECIFICATION.
An Improved Fastener for Windows, Doors, and the like.
I, FRANK PHILIP DAW of No. 42-44 Summer Row, Parade, Birmingham, in
the County of Warwick, General Brass Founder, do hereby declare the nature of
this invention to be as follows:-
This invention relates to an improved fastener for windows, doors, and the like
and consists essentially of a fastener constructed and operating in such a manner
whereby windows or doors may be securely and effectually fastened and prevented
from being opened clandestinely.
In carrying my invention into practice I make a metallic plate having two ears
projecting vertically, the said plate being provided with screw holes for attaching
to a window or door frame. The projecting ears I furnish with a pivot, to which
is pivoted, or hinged a tubular shaped lever, the connecting or hinge part of the
said lever is recessed about half the distance through the thickness thereof, .the
said recess I provide with a coil or other suitable spring pressing against two
washers one on either side thereof, the function of which is to tighten the joint of
the tubular lever between the ears, and cause it to be retained in any desired
position.
Into the tubular lever aforesaid I fit a stem, part being cylindrical and part
D shaped in section, the D shaped part I provide with a sleeve fitting loosely
I furnish the
the D shaped portion of the stem and capable of sliding therein.
cylindrical portion of the said stem with a coil spring which butts against. the
sleeve, and is held firmly at the opposite end by a washer and pin.
The outward end of the stem terminates into an ornamental knob or hook from
which depends a hook shape clip. The said stem being placed in the tubular lever
the edge thereof is turned over the outward edge of the D shaped sleeve, thus
securely fixing it in its place in the tubular lever and allowing the stem a sliding
movement therein the spring retaining it in its inward position.
I make a metallic plate having a projecting lip which is fixed by means of
screws to the window or door the said lip being in the direction of the lever, and
engaging in the depending book aforesaid.
It will be apparent that when the fastener is fixed in position on a window or
door with the depending hook engaging in the projecting lip of the plate, the
action of the spring will retain it in that position, and by drawing the ornamental
knob or hook forward the depending hook will be released from its grip of the lip,
the lever may be raised from a horizontal position to a vertical position by
moving it on its hinged joint or pivot, which will allow the window or door being
opened.

I, FRANK PHILIP DAW, of No. 42-44, Summer Row, Parade, Birmingham, in
the County of Warwick, General Brass 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 relates to an improved fastener for windows, doors and the like
and consists essentially of a fastener constructed, and operating in such a manner
whereby windows or doors may be securely and effectually fastened and prevented
from being opened clandestinely.
In carrying my invention into practice I make a metallic plate having two ears
projecting vertically the said plate being provided with screw holes for attaching
to a window or door frame. The projecting ears I furnish with a pivot to which
is pivoted or hinged a tubular shaped lever the pivot is recessed about half the
distance through the thickness thereof. Into the tubular lever aforesaid I fit a
stem like piston which I furnish with a coil spring one end butting against a
shoulder formed on the inside of the tubular lever and the opposite end against
a collar forming part of the piston.
The outward end of the piston terminates into an ornamental knob or hook. The
said piston and spring being placed in the tubular lever allows the piston a sliding
movement therein the spring retaining it in its inward position. I make a metallic
plate having a projecting lip which is fixed by means of screws to the window or
door the said lip being in the direction of the lever and engaging in the knob or
book aforesaid. It will be apparent that when the fastener is fixed in position on
a window or door with the depending hook engaging in the projecting lip of the
plate the action of the spring will retain it in that position and by drawing the
ornamental hook or knob forward the knob or hook will be released from its grip
of the lip, the lever may be raised from a horizontal position to a vertical position
by moving it on its hinged joint or pivot.
The spring pressing the collar against the round part of the pivot till the flat
part is reached when the action of the spring holds the collar firmly thereon and
retains the tubular lever in a vertical position thus allowing the window. to be
opened.
My invention may by slight modification be applied to a docr fastener.
I will now proceed to describe my invention by reference to the accompanying
drawings the same letters of reference indicating similar parts throughout.
Figures 1 and 2 illustrate in side elevation and plan respectively a window
fastener made in accordance with my invention attached to the top and bottom
sash of a window, in its closed or fastened position.
Figure 3, illustrates in side elevation (similar to Figure 1) the fastener in its
open or unfastened position.
Figures 4 and 5 illustrate my improved window fastener in horizontal section
showing the relative position of the various parts.
Figures 6 and 7 show detail parts of my invention.
Figure 8 illustrates a modification of my invention.
A, A³ are the projecting ears, B the pivot shown separately at Figure 6, B1 is
the recess or cutaway part of the pivot, C is a tubular shaped lever pivoted or
hinged by the pivot B to the ears A and A³. The stem or piston D is provided
with a collar E, the coil spring F butts against the collar E at one end and against
the shoulder H at the other. The knob I having the projecting flange K is
attached to the stem or piston D. The plate M attached to the bottom sash is
provided with an arc projection N upon which rests the lever C when in its closed

page_text: or fastened position; and the lip or hook O upon which engages the flange K of
the knob I. When the fastener is in its fastened position as shown at Figures 1, 2,
and 4, the spring F pressing against the collar E forces the knob I.against the
lip O of the plate M the flange K preventing the fastener being raised. By
drawing forward the knob I as shown at Figure 5 the flauge K is withdrawn from
the lip O and the lever C may be raised to a vertical position as shown in Figure 3.
On releasing the knob the action of the spring forces the collar E against the round
part of the pivot B the force being sufficient to raise the said lever vertically till
the collar E engages or rests on the flat part B' and is retained in that position by
the action of the spring. Figure 8 illustrates a similar window fastener in which
I use the hook P in place of the knob I the depending hook R engaging in the
hook O for the purpose of fastening.
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. An improved fastener for windows doors and the like substantially as
hereinbefore described and illustrated in the accompanying drawings.
2. A window fastener consisting of a tubular lever C pivoted at B enclosing a
spring Foperating a stem or piston D by which a window may be fastened or
unfastened by aid of the knob I and the flange K or its equivalent engaging with
the lip or hook O all operating together substantially as described and
illustrated.
3. The window fastener claimed above provided with a hinge joint or pivot for
the purpose of raising the fastener from a horizontal to a vertical position when
released from its fastening substantially as described and illustrated in the
accompanying drawings.
