PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Securing Casement Windows and
the like.
I, JOSEPH KAYE, of Bank Houso, Kirkstall, in the County of York, Lock
Manufacturer, do hereby declare the nature of this invention to be as follows:
The object of this invention is to construct an apparatus by which casement
windows and the like may be automatically secured in the position desired whether
open or closed; and to so arrange the same that they may be applied to casements or
the like whether opening inwards or outwards.
I secure a bracket to the case-
I accomplish my object in the following manner;
ment frame or to the casement, and hinge to the said bracket a bar in which are cut a
number of indentures, and upon the bar is placed a sliding sleeve hinged or centred
to a bracket secured to the casement frame or to the casement as may be required,
according to the direction in which the casement or the like is to be opened.
In the interior of the sliding sleeve is mounted a lever having a suitable projecting
end for automatically engaging with the before mentioned indentures cut in the bar,
by which the casement is secured when opened; and when the latter is to be further
opened or closed, the lever is operated by raising it at one end, or by pressing it at
the opposite end to that of the projection, thereby moving it on its fulcrum pin,
overcoming the pressure of a spring, and raising the projecting end clear of the
indentations.
When the casement is closed the bar is about parallel with the casement, and by
the end of the bar engaging with a catch, the casement is secured and cannot be
opened until the catch is liberated.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Securing Casement Windows and
the like.
I, JOSEPH KAYE, of Bank House, Kirkstall, in the County of York, Lock
Manufacturer, 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 :-
The object of this invention is to construct an apparatus by which casement
windows and the like may be automatically secured in the position desired whether
open or closed and to so arrange the same that they may be applied to casements or
the like whether opening inwards or outwards.
In order to explain my invention I will describe the same by aid of the accom-
panying drawings in which
Fig. 1. represents a portion of an outward opening casement having my improve-
ment attached thereto.
Fig. 2. is a sectional plan of same, the window being partly opened.
Fig. 3. is a view showing my apparatus socured to a casement window opening
inwards.
Fig. 4. a sectional plan of same, the window being partly open as in Fig. 2, and
Figs. 5, 6 and 7 are sectional details.
When the casement window A. opens outwards, as illustrated by Fig. 1. I secure
to the said casement a bracket B. and hinge thereto the bar C. in which are cut a
[Price 6d1

page_text: number of indentures C, upon the said bar C. is placed a sliding sleeve D. which is
centred on a pin on bracket E. secured to the casement frame F. In the interior of
the said sliding sleeve D. I mount a lever G. having a suitable projecting end G¹
for automatically engaging with indentures C₁ cut in the bar C., by which means the
casement A. is secured in any desired position when opened, and when the
casement A. is to be further opened or closed the lever G. is operated by pressing at
the end G. thereby moving it on its fulcrum pin E. and overcoming the pressure of
the spring J., thus raising the projecting end G. of the lever G. clear of the
indentations C. in the lever C., thus liberating the latter and allowing the same to
slide within the said sleeve D.
When the casement A. is to open inwards, as shown in Figs. 3 and 4, I secure
the bracket B. having the bar C. hinged thereto to the casement frame F. and secure
the bracket E. having the sleeve D. centred thereto to the casement A.
In both arrangements when the casement A. is closed the bar C. is about parallel
therewith, and by the end C. of the bar C. engaging with the catch K. secured to
the casement A., when opening outwards, and to the casement frame F. when opening
inwards, the casement is firmly secured.
The sliding sleeve D. may be provided with a handle L. having a push bar M.
passing through the centre thereof, so that when the said bar M. is pushed inwards
the end comes in contact with the lever G. operating the same on its fulcrum and
thereby raising the end clear of the indentations.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The combination of the bar C., sliding sleeve D., and lever G. with casement A.
arranged substantially in the manner and for the purpose herein set forth.
