Engineer do hereby declare the nature of my said invention to be as follows, that
is to say :-

an
and
وو
In certain improvements in the means and apparatus for fixing Window Sashes or
such like Frames for this purpose I provide a mechanical arrangement "namely
angle plate with a jointed lever attached fixed to the outer frame or Window Sash
when the lever is in a perpendicular position "that is to say "lineable with the Frame
or Sash of the Window it leaves either Sash or frame at liberty to pass up or down.
On the Bottom Sash or Frame I fit a catch with notches on or any other suitable
mechanical device so that when the lever is pulled down in a horizontal position it
becomes a fixture "more powerful than any other window fastener now in use
cannot be opened only from the Inside. According to one arrangement I provide
a horizontal lever with a joint on the end "similar to the ordinary window fastener
which has on the near end a knob fixed on a plate which is jointed and acts as a
pawl. On the bottom Frame or Sash I fix a plate which has a segmental part fixed
thereon the outside radius of the said segmental part I provide with teeth or notches
either internally or externally, when the lever is brought to right angles to bear on
the segmental part the knob acts as a pawl in the said notches or teeth and draws the
Window frames or Sashes firmly together and thus prevents any draft from passing
through the Sashes and such Sashes from being opened from the outside thereof.
also employ a smooth surface on the outer edge of the said segmental plate and the
said pawl acts as a grip or pinch which answers in the same manner as before
described.

I FRANCIS BEAUCHAMP of High Cross Tottenham in the County of Middlesex
Engineer, 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, that is to say
In certain Improvements in the means and apparatus for fixing Window Sashes or
such like Frames for this purpose I provide a mechanical arrangement "namely" a
angle plate with a jointed lever attached-fixed to outer Frame or Window Sashe
when the lever is in a perpendicular position "that is to say "lineable with the Frame
or Sashe of the Window it leaves either Sashe or Frame at liberty to pass up or
down On the bottom Sashe or Frame I fit a catch with notches on or any other
suitable mechanical device When the lever is pulled down in a horizontal position it
becomes a fixture" more powerful than any other Window Fastener now in use" and
cannot be opened only from the inside. According to one arrangement I provide a
horizontal lever with a joint on the end "similar to the ordinary Window fastener"
which has on the near end a knob fixed on a plate which is jointed and acts as a pawl
On the bottom Frame or Sashe I fix a plate which has a segmental part fixed thereon
the outsido radius of the said segmental part I provide with teeth or notches, either
internally or externally when the lever is brought to right angles to bear on the
segmental part the knob acts as a pawl in the said notches or teeth and draws the
Window Frames or Sashes firmly together and thus prevents any draft from passing
through the Sashes and such Sashes from being opened from the outside thereof.
I also employ a smooth surface on the outer edge of the said segmental plate and the
said pawl acts as a pinch or grip which answers in the same manner as before described
Figure 1. of the accompanying Drawings represents the fastener complete provided
with a segmental part with notches placed on the top and marked A. the pawl B is
fixed to a knob C which act in the notches and secures the window at any angle On
its outer end is a joint D working in end of lever E. fig. 2 is a side view of knob and
pawl combined and lettered as before described-fig. 3 showing segmental plate with
notches on the outer edge F with pawl and knob marked G which turns on a pivot H
working in lever 1-fig. 4 is a side view of knob and pawl combined and fettered.
Fig. 5 is a side view of a perpindular window fastener J is a segmental plate with
notches placed on the outer edge-K L is the knob and pawl working on pivot M on
the end of lever marked N.
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 :-
1st. A series of notches on a segmental part of a circle A F J for the purpose of
tightening Window Sashes at any angle to prevent the shaking and rattling of
windows.
2nd. A window fastener so constructed that it cannot be opened from the outside
by a knife or any such like instrument.
3rd. My adjustable fastener for window Sashes as before described and shown by
the accompanying drawings 1, 2, 3 4. & 5.
