PROVISIONAL SPECIFICATION.
Improvements in Sash and like Fastenings.
I, GEORGE POWELL DAVIES, of 4, Canon Street, Aberdare, in the County of
Glamorgan, Architect and Surveyor, do. hereby declare the nature of this inven-
tion to be as follows:
This invention relates to improvements in sash and like fastenings.
According to the invention I provide a plate adapted to be secured to the
meeting-rail of the upper sash, in the case of a window fastening, and which is
provided on its upper face with an upwardly projecting lug arranged at an
inclination thereto, preferably at an angle of 45° with the parallel sides thereof.
To this inclined lug I pivot an arm or lever, the said arm or lever being so bent
with respect to its bearing surface that when the fastening is undone or open,
it lies parallel to the meeting-rail of the upper sash and when in its closed
position perpendicular thereto; that is to say, the said arm is preferably bent
at an angle of 135° with the bearing portion thereof. The armi is curved in-
wards at its outer end and the curved portion is provided with a spring-pin.
The meeting-rail of the lower sash is provided with a plate, the upper surface
of which is furnished with a projection having a hole or recess designed to receive
the spring-pin when the arm or lever is moved into position for fastening the
window.
With this arrangement, to fasten the window the arm or lever is raised and by
virtue of its upward movement, it turns through an angle of 90° so that it is
caused to project from the upper sash and over the catch upon the plate secured
to the lower sash, the spring-pin taking into the recess in the projection so as to
securely hold the sashes together. To unfasten the window it is only necessary
to release the spring-pin from the recessed projection and to then turn the arm
upwards whereby it is swung back through an angle of 90° and comes to lie
parallel with the sides of the meeting-rail of the upper sash.
It will be obvious that, although I have described my improvements as applied
to sash fastenings, the said improvements can be equally well adapted to fasten-
ings of a like nature.

Glamorgan, Architect and Surveyor, do hereby declare the nature of this inven-

page_text: tion, 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 improvements in sash and like fastenings.
According to the invention I provide a plate adapted to be secured to the
meeting-rail of the upper sash, in the case of a window fastening, and which is
provided on its upper face with an upwardly projecting lug arranged at an
inclination thereto, preferably at an angle of 450 with the parallel sides thereof.
To this inclined lug I pivot an arm or lever, the said arm or lever being so bent
with respect to its bearing surface that when the fastening is undone or open,
it lies parallel to the meeting-rail of the upper sash and when in its closed
position perpendicular thereto, that is to say, the said arm is preferably bent
at an angle of 135° with the bearing portion thereof. The arm is curved
at its outer end and the curved portion is provided with a spring-pin.
The meeting-rail of the lower sash is provided with a plate, the upper surface
of which is furnished with a projection having a hole or recess designed to receive
the spring-pin when the arm or lever is moved into position for fastening the
window.
In the accompanying drawing,—
Figure 1 is a plan view shewing a sash fastening made according to my inven-
tion and applied to the meeting-rails of window sashes, the said fastening being
shewn in its locked position:
Figure 2 is a view similar to Figure 1 but shewing the fastening unlocked':
Figure 3 is a sectional end elevation shewing the fastening in the position
illustrated in Figure 1.
A is the meeting-rail of the upper sash and B the meeting-rail of the lower
sash. a is the plate which is secured to the meeting-rail A and a¹ is the up-
wardly projecting lug with which the said plate a is provided, the said lug being
arranged at an angle of 45° with the parallel sides of the plate a, as clearly
shewn in the drawing. bis the arm or lever which is pivoted to the inclined
lug a¹ and the body of which is bent at an angle of 135° with the pivot portion,
so that when the fastening is undone it lies parallel with the meeting-rail A,
as shewn in Figure 2, and when in its closed or locked position perpendicularly
thereto, as shewn in Figure 1. As above mentioned this arm b is curved at its
outer end, as shewn at b¹, and is provided with a spring-pin
C.
e is the plate with which the meeting-rail B is provided and e¹ is the projec-
tion with which the said plate e is furnished; f is the hole or recess formed
on the outside of the said projection e for receiving the spring-pin c when
the lever b is moved into the position for fastening the window shewn in Figures 1
and 3.
With this arrangement, to fasten the window the arm or lever b is raised and
by virtue of its upward movement it turns through an angle of 90° so that it is
caused to project from the upper sash rail A and over the projection e¹ upon
the plate e secured to the rail B, the spring-pin e taking into the recess fin
the said projection, as above described, so as to securely hold the sash rails A
and B together. To unfasten the window it is only necessary to release the spring- 4
pin e from the recess f in the projection e¹ and to then turn the arm 6 upwards,
whereby it is swung back through an angle of 90° and comes to lie parallel with
the sides of the meeting-rail A, as shewn in Figure 2.
It will be obvious that, although I have described my improvements as applied
to window sash fastenings, the said improvements can be equally well adapted 5
to fastenings of a like nature.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
:-
1. A sash or like fastening comprising a plate adapted to be secured to one 5.

page_text: meeting-rail (or its equivalent) and having an inclined projection to which is
pivoted an arm or lever the body of which makes a suitable angle with respect
to the pivoted portion and is provided at its outer end with a spring-pin or the
like, and a second plate adapted to be secured to the other meeting-rail (or its
equivalent) and provided with a projection having a recess into which the spring
pin is adapted to take when the aforesaid arm is turned into the locking position,
substantially as herein before described.
2. The manufacture and use of the improved fastening hereinbefore described
and illustrated in the accompanying drawing.
