I, HERBERT STANLEY HARRIS, Cashier, Aston Lower Grounds, Birmingham do
hereby declare the nature of this invention to be as follows:-
I affix to the top ledge of the lower sash of an ordinary window a plate of brass or
other material as per sketch A, the said plate having two sides (sketch B) fixed at
right-angles to it. A lever shaped as sketch C is secured between these sides by
means of a pin running through it at point CA, and through the said sides at B B.
Fastened to the plate A under one end of the lever (C B) I place a spiral or other
spring, and over the same end of the lever-fastened to each of the sides B-I put a
pin or small piece of metal which spring & pin keep the lever in position for use.
the lower ledge of the top sash of an ordinary window I affix a piece of metal or
catch as per sketch D..
To
With these apparatus, on an ordinary window being closed (by pulling down the
lower sash or lifting the upper sash) the end of the lever CC and the catch D meet
and lock automatically, thus rendering it impossible for the window to be closed
without being secured, and also it being secured it cannot be opened from the outside.
When opening the window it is only necessary to press the end of the lever C B
thereby depressing the spring and unlocking the fastenment.
I also apply these catches or fasteners to casement and other windows opening
laterally.

Improvements in Window Fastenings.
I, HERBERT STANLEY HARRIS Bishop's Castle, Shropshire, Cashier at Aston Lower
Grounds Birmingham 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:-
I affix to the top ledge of the lower sash of an ordinary window a plate of brass or
other metal, having sides attached to it at right angles similar to sketch A-a lever
shaped as sketch B is secured between the beforementioned sides by means of a pin
running through it & the sides at A B-under the end of this lever B C I place a
feather or other ordinary spring, and over the same end of the lever I put a pin
attached at each end to the sides, see A C, which spring and pin keep the lever in
position for use-To the lower ledge of the top sash of the window I fasten a piece of
metal or catch as per sketch D-given an open window, with these apparatus attached
as described, on the window being closed, by drawing down the lower sash or raising
the upper sash, the end of the lever B E and the catch D meet and lock automatically,
thus rendering it impossible for the window to be properly closed without being
secured; also, the locking action of the lever and catch is such that the sashes are
drawn close together and any rattling or shaking by the wind or other causes avoided-
the window cannot be opened from outside without burglar-like force being used.
To open or unfasten the window it is only necessary to press the end of the lever BC,
the spring being thereby depressed and the catch released.
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) The combination of the lever, catch, spring, and plate with sides, as above
described, only in so far as the said combination may be used as a window catch or
sash fastener and (2) I claim this window catch or sash fastener as my Invention-
I do not claim as actually new in itself any piece or portion of the aforesaid combination.
(3) the features of novelty I claim in my Invention are
(1) The automatic action of fastenment.
(2) The security of the fastenment.
(3) The preventing of the sashes shaking when the window is fastened-but, I claim
these features of novelty only in so far as the manner in which they can be or are
brought about by my Invention.
