page_text: 1, WALTER KINSEY BOOTH of 21ª Exchange Buildings, St. Mary's Gate Manchester
in the county of Lancaster Architect do, hereby declare the nature of this invention
to be as follows :-
I employ a lever or hasp somewhat similar to the ordinary fastener such lever being
centred either upon the frame of one of the sashes or upon the fixed window or door
frame and sweeping over a portion of the other sash. At its free end in place of the
ordinary button I form the lever so as to carry a screw whose axis is parallel with the
length of the lever and whose inner end abuts against a bracket carried by the second
sash. The outer end of the screw is formed with a suitable thumbnut or milled head.
The bracket against which the screw abuts is formed with a suitable slot into which
the lever enters when swung into position for fastening, and it may have a recess
into which the end of the screw shall enter when it is rotated in the direction for
fastening the sash.
•
A collar is formed on the inner end of the screw to prevent its being screwed out
of its place and so lost.
When used for ordinary window sashes I form the base plate or flange of the
bracket attached to the inner or lower sash wide enough to overlap and so to protect
the joint between the sashes.
The action is as follows:-
The window or door being closed the lever is swung into position over the sash and
the screw immediately tightened down when the sash or door is drawn close to its
companion sash or to its frame thus excluding draughts and preventing rattle.
The entering of the end of the screw into a recess locks the sash or door and
prevents the possibility of its being opened by insertion of a knife or thin article
between the sashes.

page_text: Improvements in Fasteners for Window Sashes and the like.
I, WALTER KINSEY BOOTH of 21ª Exchange Buildings, St. Mary's Gate Manchester
in the county of Lancaster Architect, 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 :-
•
I employ a lever or hasp somewhat similar to the ordinary fastener such lever being 5
centred either upon the frame of one of the sashes or upon the fixed window or door
frame and sweeping over a portion of the other sash. At its free end in place of
the ordinary button 1 form the lever so as to carry a screw whose axis is parallel
with the length of the lever and whose inner end abuts against a bracket carried by
the second sash. The outer end of the screw is formed with a suitable thumbnut or 1
mild head. The bracket against which the screw abuts is formed with a suitable
slot into which the lover onters when swung into position for fastening and it has a
circular recess into which the end of the screw shall enter when it is rotated in the
direction for fastening the sash.
A collar is formed on the inner end of the screw to prevent its being screwed out 1
of its place and so lost.
In the accompanying drawings
Fig. I. is a Plan view of my invention showing the lever and scrow in position for
fastening window but before screwing up.
Fig. II. is a Plan view shewing the fever thrown back preparatory to opening the 2
window.
Fig. III. is a sectional elevation corresponding with Fig. I.
Fig. IV. is a detached front elevation of the slot Bracket.
Fig. V. is a detached front elevation of the lever and its Bracket.
In all the figures the same reference letters refer to the same parts.
A is the outer sash and B is the inner sash of a window.
The lever bracket a is secured to sash A by screws in the ordinary manner as
shown, and bis similarly secured to the sash B. The lever or hasp c is centred at c¹
in the ordinary manner and sweeps over a portion of sash B as shewn by dotted lines
in Fig. II. At its free end the lever is formed with a boss or swell c" so as to carry 3
a screw d parallel with the lever. Its inner end is formed as shown and it abuts
against the bracket 6 having the projection 6' formed upon it for the purpose and I
prefer to form a circular recess in the face of 6¹ corresponding with the end of the
Screw d and into which it shall enter when screwed up.
The outer end of the screw is formed with a thumb-nut or milled head d' as shewn. 3
The slot 61 formed in bracket b is for the purpose of allowing the arm of lever c
to pass under 6' and the end of the slot arrests the arm when in position for
screwing up.
•
An enlargement or collar d" is formed or fixed near to the end of the screw to
prevent its being screwed out and so lost.

page_text: The spring e acts upon a knuckle on the boss of lever c in the ordinary
manner.
In some cases I allow the base plate of bracket b to overlap the joint between the
sashes as an additional security.
The action is as follows:-
The window or door being closed the lever c is swung into position over the sash
as shewn in Fig. I. and the screw d is immediately tightened against the abutment b¹
when the sashes are drawn close together thus excluding draughts and preventing rattle.
The entering of the end of the screw d into a recess securely locks the sash and
prevents the possibility of its being opened by the insertion of a knife or thin article
between the sashos and the upper edge of the recess assists the projection b¹ of bracket
in resisting any attempt to drive the lever upwards by pressure exerted by means of
an instrument inserted through the space between the sashos.
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 :-
I. The straight lever entering into a slot and carrying a screw substantially
as and for the purposes herein before described and illustrated in the accompanying
drawings.
II.. The fixed-bracket having a slot formed in it and embracing the lever substan-
tially as and for the purposes hereinbefore described and illustrated in the accompanying
drawings.
III. The circular recess in the fixed bracket to receive the screw end substantially
as and for the purposes herein before described and illustrated in the accompanying
drawings.
IV. The enlargement or collar on the end of the screw substantially as and for the
purposes herein before described and illustrated in the accompanying drawings.
