Improvements relating to Casement Stays for Window or Fan-light
Fasteners and the like.
I, THOMAS REDFERN LEIGH, of Lindeth Lodge, Fog Lane, Didsbury near
Manchester, Ironmonger, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The improvements relate to casement stays used for window or fan-light
fasteners and the like, and have for object to ensure the notches or holes in the stay
bar falling into the locking position automatically without the necessity of the
bar being placed in the requisite position by hand, as, for the most part, heretofore.
But that the improvements may be better understood, I will, with the aid of the
accompanying sheet of drawings, explain the means employed by me.
Fig. 1 is a perspective view of one form of my invention, and Figs. 2 and 3 are
perspective views of portions of casement stay bars shaped in accordance with other
forms of my invention.
The same letters indicate corresponding parts wherever they occur.
a is a casement stay bar formed at one extremity preferentially with a double or
universal joint, or it might be a ball and socket joint, in connection with a piece or
bracket b which is attached to the casement requiring to be opened or shut. The
stay bar a is provided, in the case of Fig. 1, with a number of holes a¹ along its
length, but in the cases of Figs. 2 and 3 side slots a² are provided in lieu thereof.
The stay bar a passes through a guide piece c which swivels on a fixture c¹ attached
to the frame or other immovable part of the window. The pin on which the
guide c swivels is in Fig. 1 carried up a sufficient distance to enable it to engage
with the holes a¹ in the stay bar a when the latter is in a correct position for the
locking action to take place, while for the form of stay bar shown in Figs. 2 and 3,
a side lug or lugs, or other projections, may be provided for this purpose.
It will thus be seen that after the stay bar a has been lifted clear of the projec-
tion in the guide piece c, and pushed or pulled longitudinally in order to open or
close the casement, such bar may then be allowed to fall by its own weight upon
the projection or lug, and when a hole or slot in such stay bar comes in conjunc-
tion with a projection or projections passing through or forming part of piece c the
locking action will take place without the necessity of the holes or slots being
guided into position by hand.
Variations in detail may be made, such as in the particular formation of the
stay bar a, and its connection with the casement, together with the shape and
number of the holes or slots therein; and also in the formation of the swivelled
guide piece c, and the bracket or fixture carrying the same. without departing from
the peculiar character of the invention.

page_text: Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is :-
For window or fan-light fasteners in which casement stays are used, a stay bar
formed with holes, slots or notches therein, and guided by a guiding piece
swivelling on a fixture, such swivelled piece being formed with a projection for
engaging with the holes, slots or notches in the stay bar, for the purpose and in
manner substantially as herein shown and described.
