PROVISIONAL SPECIFICATION.
Improvements in Fastenings for Securing Windows and Doors, and
for other like purposes.
I, WILLIAM HOUGHAM, of 39 Temple Row, in the City of Birmingham,
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention consists of improvements in fastenings for securing windows and
doors, and for other like purposes, my object being to construct a neat and durable
fastening from few and simple parts, and in such a manner that the door, window,
or other movable fitting or article to which it is attached, may be very readily and
effectually secured in its closed position.
In the application of my invention in one convenient manner to the construction
of a fastening for securing together in their closed positions the two sliding sashes
or frames of an ordinary window, I form a catch plate or fastening piece from
brass or other metal, and attach the same to the back or outer sash or window
frame.
I preferably stamp the catch plate or fastening piece from sheet metal providing
a projection or lug for engagement by the catch which is pivotted upon the front
or inner sash or window frame. The catch is preferably stamped from sheet metal,
to a semi-circular or other suitable shape or configuration, and has a slot formed
through it, which engages with the projection or lug from the catch plate on the
back sash.
The engaging slot or aperture is made to a curved or circular path, and at its
outer end the metal of the catch is turned up to strengthen the slotted portion and
to form a mouth to receive the projection or lug from the catch plate, and thus to
allow the slotted catch to pass over the plate until the inner end of the slot is
brought against the lug.
I attach a knob or finger piece to the semi-circular or other catch for convenience
in turning it upon or about its pivot. The pivot is attached to a plate which is
secured to the upper part of the front or inner window sash or is formed with a
screw thread upon it for direct attachment to the sash.
The position of the slot in the pivoted catch is preferably such that in passing
over the lug or projection from the catch plate, it draws the two sashes towards
each other, and thus in addition to being secured the two sashes are clamped
together. When completely closed the lug projects over the outer edge of the
front or inner sasb, and the outer curved edge of the catch provides an effectual
obstruction against a knife or other implement that may be inserted between the
sashes in an attempt to force open the window.
The application of my invention to the construction of fastenings for doors, and
for other purposes, differs only in the modification of the parts to suit the particular
service required, from the application to the construction of a window fastening as
hereinbefore described.

1, WILLIAM HOUGHAM, of 39, Temple Row, in the City of Birmingham,
Merchant, de 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 improvements in føstenings for securing windows and
doors, and for other like purposes, my object being to construct a neat and durable
fastening from few and simple parts, and in such a manner that the door, window,
or other movable fitting or article to which it is attached, may be very readily and
effectually secured in its closed position.
In the accompanying sheet of explanatory drawings to be hereinafter
referred to :-
Figures 1, 2 and 3 represent one form of window sash fastener constructed in
accordance with my invention, Figure 1 being a plan of the fastener when closed,
Figure 2 a similar view representing the fastener partially opened, and Figure 3 a
front elevation of the fastener.
Figure 4 is an elevation, and Figure 5 a plan of one modified form of my
window sash fastener, whilst Figures 6 and 7 similarly represent another
modification.
The same reference letters in the different views indicate the same parts.
In the application of my invention in one convenient manner to the construction
of a fastening for securing together in their closed positions the two sliding sashes
or frames of an ordinary window, I forin a catch plate or fastening piece such as A
from brass or other metal, and attach the same to the back or outer sash or window
frame.
I preferably stamp the catch plate or fastening piece A from sheet metal
providing a projection or lug A' for engagement by the catch B which is pivotted
upon the front or inner sash or window frame. The catch B is preferably stamped
from sheet metal, to a semi-circular or other suitable shape or configuration, and
has a slot formed through it, which engages with the projection or lug A¹ from the
catch plate A on the back sash.
The engaging slot or aperture is made to a curved or circular path, and at its
outer end the metal of the catch is turned up to strengthen the slotted portion and
to form a mouth to receive the projection or lug from the catch plate, as illustrated
at Figure 3, and thus to allow the slotted catch to pass over the plate until the
inner end of the slot is brought against the lug.
I attach a knob or finger piece C to the semi-circular or other catch for
convenience in turning it upon or about its pivot D. The pivot D is attached to
a plate E which is secured to the upper part of the front or inner window sash, or
the pivot may be formed with a screwed stem for direct attachment to the sash
without the employment of the plate E.
The position of the slot in the pivotted catch is preferably such that in passing
over the lug or projection from the catch plate, it draws the two sashes towards
each other, and thus in addition to being secured the two sashes are clamped
together. When the catch is completely closed its curved edge provides an
effectual obstruction against a knife or other implement that may be inserted between
the sashes in an attempt to force open the window.
In the modified form of fastener shown at Figures 4 and 5, I dispense
with the knob C (Figures 1 to 3) and form the finger piece B¹ as a part of the
catch R

page_text: With the form of fastener shown at Figures 6 and 7, I dispense with the slot
in the catch B, and cause the upturned circular edge B² to engage with the lug A¹
of the catch plate.
The application of my invention to the construction of fastenings for doors, and
for other purposes, differs only in the modification of the parts to suit the particular
service required, from the application to the construction of a window fastening as
hereinbefore described.
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 fastenings for securing windows and doors and for other like purposes the
use of a pivotted catch having a curved slot formed through it or provided with an
upturned circular edge in such a position as to cause the catch when turned upon
its pivot to engage with a fixed lug or projection substantially as described and as
illustrated.
2. The improved window fastener consisting of a catch such as B pivotted upon
the front or inner sash or frame and having a curved slot formed through it, or
provided with an upturned circular edge for engagement with the lug or projection
from a catch plate or fastening piece secured to the back or outer sash or frame,
and arranged substantially as described and as illustrated.
Dated this 5th day of September 1896.
