TRUVIDIUNAD NIMOIFICATION
Improvements in and relating to Windows.
I, SAMUEL BAXTER, of 43, Clarendon Road, Seedley, Pendleton, near
Manchester, Joiner, do hereby declare the nature of my said invention to be as
follows:-
Instead of nailing the cord in the groove formed in the edge of the sash as
hitherto I employ a lever catch mounted upon a screw stud in a recess formed to
receive it in the edge of the sash.
The shorter arm of this lever catch is serrated
at its extremity and is held free from the sash framework so long as the sash cord
is intact but immediately the cord (which in this case is attached to the longer arm
of the lever) breaks, then the serrated arm turns upon its axis and catches in the
sash framework, so locking the sash in position and effectually preventing its
falling. I prefer to fasten the catch by passing the same through a double eyed
hole and then drawing its end back so as to allow it to be gripped between the
catch and the recess in which it works.
Dated this 10th day of June 1890.

Improvements in and relating to Windows.
I, SAMUEL BAXTER, of 43, Clarendon Road, Seedley, Pendleton, near
Manchester, Joiner, do hereby declare the nature of my said invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
-39-
On the accompanying drawing Fig. 1 is a front view and Fig. 2 a side view of
as much of a window sash as is necessary to shew my improvements applied
thereto.
Figs. 3 and 4 are similar front and side views but shewing the sash cord broken
and the serrated arm of my improved lever catch engaging with the sash
framework.
Figs. 5, 6 and 7 are full size detail views of the improved lever catch.
In carrying out my invention instead of nailing the cord in the groove formed in
the side of the sash as heretofore, I employ a lever-catch a mounted upon a screw
stud bin a recess c formed to receive it in the edge of the sash d. The shorter
arm of this lever-catch is serrated at its front extremity as illustrated and is held
free from the sash framework e so long as the sash-cord is intact but immediately
the cord (which is attached to the longer arm of the lever catch) brakes, the
serrated arm turns upon its axis and catches in the sash framework as illustrated in
Figs. 3 and 4 so locking the sash in position and effectually preventing its
downfall.
The screw stud is provided with additional screw threads y and a lock-nut / to
enable me to lock the screw-stud in position.
I prefer to fasten the cord by passing it through holes i, i its end being nipped
by coming against the shoulder j.

page_text: Having thus 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 —
1st. The improved means of and apparatus for preventing the. falling of sliding
window-sashes substantially as hereinbefore described and illustrated on the
accompanying drawing:
2nd. The employment of a lever-catch pivoted. in a recess. formed in the side of
the window-sash and serrated at one end and connected to the sash-cord at the
other substantially as and for the purposes hereinbefore described.
