PROVISIONAL SPECIFICATION.
Improvements in connection with Casement Stays for Windows,
Fanlights, and the like.
I, THOMAS REDFERN LEIGH, of Lindeth Lodge, Fog Lane, Didsbury, near
Manchester, Ironmonger, do hereby declare the nature of this invention to be as
follows:-
The improvements relate to casement stays for windows, fanlights, and the like,
and have for object to provide means whereby. the stay bar is securely retained
in any of the locking positions.
To accomplish this and to effect my improvements, I provide a guide-piece,
through which the stay-bar passes, which guide-piece is attached to the window-
frame, or other immovable surface, but is capable of swivelling in a horizontal
plane to accommodate the varying angles through which the stay bar is required
to pass as the window or the like is opened or closed.
But this guide-piece per se forms no part of this my present invention.
The stay bar is of any suitable formation, but, by preference, T shaped in
cross section, whereby a flat surface is presented above, while along the bottom.
of the stay bar suitable notches are cut or otherwise formed at convenient dis-
tances, which notches are capable of engaging with a stud, or other projection,
within the guide before mentioned.
From any convenient part of this guide-piece, but above the bar, I suspend a
pawl, or catch, which, when the stay bar is raised to disengage the notch from
the stud, is caused to rest at an angle upon the upper surface of the bar, and
permits of such bar being moved freely; but as soon as the bar falls to engage
in the locking position, this pawl assumes the vertical by gravity, and forms an
abutment, until turned aside by hand, which prevents the bar from being acci-
dentally unlocked..
To ensure the bar being firmly held in the locked position, I may form the
notches in the bar of greater width at the bottom than the top, and the stud on the
guide, which engages therewith, may be correspondingly formed taper, by which
means close contact is obtained, and vibration from looseness, consequently,
obviated.
Variations in detail, such as the design and material of the various parts, may
be made without departing from the peculiar character of the invention.

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 for windows, fan-lights, and the
like, and have for object to provide means whereby the stay bar is securely retained
in any of the locking positions.
To accomplish this and to effect my improvements, I provide a guide-piece,

The stay bar is of any suitable formation, but, by preference, T or shaped
in cross section, whereby a flat surface is presented above, while along the bottom
of the stay bar suitable notches are cut or otherwise formed at convenient dis-
tances, which notches are capable of engaging with a stud, or other projection,

From any convenient part of this guide-piece, but above the bar, I suspend

notches in the bar of greater width at the bottom than the top, and the stud on
the guide, which engages therewith, may be correspondingly formed taper, by
which means close contact is obtained, and vibration from looseness, consequently,

But that the improvements may be better understood, I will, with the aid of
the accompanying drawings proceed more fully to describe means employed by
me.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation, and Fig. 2 a side section, of a stay-bar guide piece
provided and arranged in accordance with one form of my improvements, and
shown in conjunction with a portion of a T stay-bar; while Fig. 3 is a sectional
elevation at right angles to Fig. 1.
Fig. 4 is a side section of a guide piece provided and arranged in accordance
with another form of my improvements, and shown in conjunction with a portion
of a 1 stay bar; and Fig. 5 is a sectional elevation at right angles to Fig. 4;
while Fig. 6 is a general view of a stay bar in position within the guide.
The same letters indicate corresponding parts wherever they occur.
a is the guide piece, capable of swivelling upon the foot or base b by means
of the pin or extension a¹.
c is the stay-bar, represented in Figs. 1, 2, and 3, as T shaped in cross section,
and provided along the lower portion with notches c¹, any one of which is capable

page_text: of fitting over a corresponding projection or stud a² upon the guide piece a, when
brought into position for locking the bar.
In Figs. 4, 5, and 6, the stay bar is represented as of shape in cross section,
and notches c are formed in both the vertical sides thereof, so as to fit over and
lock with the part a³ of the guide a, which part a³ forms a projection in lieu of
the stud a², whereby the latter may be dispensed with.
which
dis the pawl, suspended from the guide piece a, and above the bar
pawl is raised when it is desired to disengage a notch of the bar from the retaining
stud or projection, and rests at an angle on the upper surface of such bar, as
shown in Fig. 1. But as soon as any notch comes above the stud or projection
aforesaid, the bar falls into engagement with the latter, and the pawl d assumes
the vertical by gravity, thereby locking the bar.
e represents a portion of a window frame or other fixture to which the foot or
base 6 of the guide is attached, and f is a part of a window, fanlight or the like,
requiring to be operated by the stay bar c.
Variations in detail, such as in the manner of connecting the pawl d to the
guide, and in the design and material of the various parts, may be made without
departing from the peculiar character of the invention.
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:
-
For window or fanlight fasteners in which casement stays are used, the combi-
nation of a guide piece, swivelled on a fixture, and through which the stay bar
operates, with a pawl or catch connected to the guide piece and forming an abut-
ment above the stay bar, for the purpose and in manner substantially as herein
shown and described.
