I, FREDERICK RAYNER 4 St. Ann's Road Gecenhill Harrow, 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 :-
A piece of metal or other substance with slot hole is inserted into or attached
to the window sill. AT piece working in this slot hole forms a runner to which
is attached a square tapped spindle round which a collar fixed to an arm works.
This collar is scored on upper side, and a corresponding collar working on the
square spindle, by means of a thumb screw and carrier, is similarly scored on
lower side.
The underside of the piece of metal or other substance is scored and the runner
is scored on upper side to correspond the whole is clamped together or released by
means of the thumb screw. The other end of arm is attached to the window sash
in the usual manner.
In order that my invention may be fully understood I will now refer to the
annexed drawings in which :-
Figure 1. is a front elevation showing my invention applied to a window.
Figure 2. sectional plan view of same.
Figure 3. sectional elevation of fastener to enlarged scale showing the clamp
through line xy.
The
Referring to Figures 1, 2 & 3 a is the window hinged at b to the frame c.
rod d is pivoted at e to the window a and terminates in the toothed boss f which
engages in a corresponding toothed piece g which may be caused to engage or
disengage with the boss f by means of the thumb piece / which raises or lowers the
part g upon the spindle i. The end ; of the spindle i carries a toothed plate k

by screws m.
By this means it will be seen that the window may be opened & secured in
position by means of the thumb piece h upon the slotted rack plate / said thumb
piece causing the teeth on the boss f & part g to engage together & at the same
time causing the toothed plate k to engage on the slotted rack plate l.
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. The combined construction & arrangement of the various parts substantially
as described & illustrated herein.
