PROVISIONAL SPECIFICATION.
Improvements in Window and other Fasteners, Specially Applicable
to Sashes, Casements, Doors, and for other similar purposes.
I WALTER WILLIAM CURTIS of 10 Milton Road Fitzhugh, Sonthampton in the
County of Hampshire Draughtsman do hereby declare the nature of this invention to
be as follows
This invention relates to an improved mode or method for fastening and securing
window sashes casements doors shutters, and other similar purposes so as to firmly
secure them from being opened from the outside.
I will describe my invention as applied to a sash fastener.
1 take and provide a metal plate to be fastened in a suitable manner to the upper
window sash to which is attached a hinged bar worked by a spring as is usual in
ordinary window sash fasteners.
Into this bar in a recess formed for the purpose another plate or bar is fitted which
will move backwards and forwards in the recess in the first named hinged bar by means
of a spring enclosed in the recess formed in the same.
I also provide on the lower sash another plate of metal firmly secured thereto and
at a suitable distance apart for the purpose from the before mentioned plate on the
upper sash in this plate on the lower sash a recess is formed into which the extremity
of the sliding bar on the upper sash enters when in the act of closing the fastener and
when it is desired to unlock the fastener it is only necessary to push back the sliding
bar in the direction of the glass in sash frame when the fastener is unlocked and the
hinged bar attached to the plate on the upper sash frame and worked by a spring as
is usual in sash fasteners can be returned to its original unlocked position and the
window is free to be opened.
In the case of French casements and shutters &c. the plates referred to together
with the hinged bar and other necessary attachments or connections as before described
would to suit these circumstances be somewhat suitably disposed in a similar manner
on either side.
The parts of the fastener comprised in my invention may be made of wrought
malleable or cast iron steel brass or other suitable metal or alloy.

COMPLETE SPECIFICATION.
Improvements in Window and other Fasteners, Specially Applicable
to Sashes, Casements, Doors, and for other similar purposes.
I WALTER WILLIAM CURTIS of 10 Milton Road, Fitzhugh, Southampton in the
County of Hampshire Draughtsman, 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 :-
This invention relates to an improved mode, or method, for fastening and securing
window sashes casements doors, sbutters and other similar purposes so as to firmly
secure them from being opened from the outside.
I will describe my invention as applied to a sash fastener.
I take and provide a metal plate to be fastened in a suitable manner to the upper
window sash to which is attached a hinged bar worked by a spring as is usual in
ordinary window sash fasteners.

page_text: Into this bar in a recess formed for the purpose another plate or bar is fitted which
will move backwards and forwards in the recess in the first named hinged bar, by
means of a spring enclosed in the recess formed in the same.
I also provide on the lower sash another plate of metal firmly secured thereto and
at a suitable distance apart for the purpose from the before mentioned plate on the
upper sash in this plate on the lower sash a recess is formed into which the extremity
of the sliding bar on the upper sash enters when in the act of closing the fastener, and
when it is desired to unlock the fastener it is only necessary to push back the sliding
bar in the direction of the glass in sash frame when the fastener is unlocked and the
hinged bar attached to the plate on the upper sash frame and worked by a spring as is
usual in sash fasteners can be returned to its original unlocked position and the window
is free to be opened.
In order to enable my invention to be fully understood I will proceed to describe
same with reference to the accompanying drawing in which
Fig. 1 is a sectional elevation through a, b.
Fig. 2 a plan on top of same both these views shewing the fastener when closed or
locked.
Fig. 3, an elevation, and
Fig. 4, a sectional plan through c, d, both these views shewing the fastener when
the bolt L, is upon the point of entering the recess S, in the plate D.
Fig. 5, is a section through line A, A.
Fig
6 a section through line B, B. C, is the plate attached to the upper
sash G-D, the plate attached to the lower sash H.
A groove E, in plate D is provided for the purpose of allowing a projection F, to
work in same, whereby in closing the fastener the two sashes are brought closely
together.
The knob K, it is noted is screwed, or otherwise fastened, into the bar or bolt L;
and works backwards and forwards in the slot N, on top of bar M, the length of
this slot regulates the possible in and out movement of the bolt L. In unlocking
the fastener the knob K, and consequently the bolt L, is pushed back towards the sash
glass.
In bringing the fastener to the locking position the spring P, is compressed
until the holt L, arrives at the recess S, in the plate D, when the spring reacts
upon the bolt L, causing it to shoot into the recess S, thereby locking the
fastener.
The spring Qby its action upon the bar M, assists in opening and closing
the fastener; other similar spring arrangements may be fitted to my fastener for
this purpose.
It is noted that it is possible and convenient to unscrew the knob K, and remove same
thereby making it practically impossible, or at least very difficult, to unlock the fastener
until the knob is replaced; thereby adding to the security of the fastener.
In the case of French casements, and shutters, &c., the plates referred to together
with the hinged bar and other necessary attachments or connections as before described
would to suit these circumstances be somewhat suitably disposed in a similar manner
on either side.
The parts of the fastener comprised in my invention may be made of wrought,
malleable, or cast iron, steel, brass, or other suitable metal or alloy.
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 :-
1st. The securing of windows, casements, doors, shutters, and similar fittings, by
means of the arrangement or similar thereto as berein set forth and shewn upon the
accompanying drawings.
2nd. The arrangement of a spring P, within the bar M, acting upon the bolt L, and
the corresponding parts.

page_text: 3rd. The moveable knob K, in combination with the parts claimed in claim 2.
4th. The particular application and method of instantly and easily bringing together,
and securing, the sashes of windows, casements, doors, and shutters, in manner herewith
described and set forth.
