PROVISIONAL SPECIFICATION.
Improvements in and relating to Window Sash Fasteners and
the like.
I, GEORGE TOMKINSON, of Church Street, West Smethwick, Furnace Builder, do
hereby declare the nature of this invention to be as follows:-
:-
This invention relates to an attachment for use in connection with window sash
fasteners of the ordinary type or of other suitable kinds.
For my purpose I secure horizontally a steel spring arm to the top of the inside
meeting bar of the window sash. This spring arm is connected at its one end
with or made integral with a vertical piece bolt or stud which takes into a corres-
ponding hole in the meeting bar.
The position of this spring arrangement is immediately in front of the arm of
the window fastener when closed and the action is thus.
Given that the sash fastener is unlocked in turning the arm to lock same it
passes over the spring arm and depresses it the bolt entering the hole above named
as soon as the fastener is brought home and locked in the usual manner the bolt
rises by the action of the spring arm and so projecting above the meeting bar
effectually prevents the sash fastener from being pushed back and unlocked until
the combined spring and bolt is pressed down from the inside of the window when
the sash fastener can be readily passed over it and into its open position.
As will be understood my improved appliance can be readily adapted for al!
existing window fasteners such as ordinarily used or where arrangements will
admit of my system being employed as it is only necessary to bore a vertical hole
in the mid-horizontal bar and attach the spring arm and bolt in manner ::lready
indicated.
Improvements in and relating to Window Sash Fasteners and
the like.
I, GEORGE TOMKINSON, of Church Street, West Smethwick, Furnace Builder, 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
[Price 8d.1

page_text: statement, reference being had to the drawings accompanying this Specification
and to the figures and letters shewn thereon.
My invention relates to an attachment chiefly for use in connection with
window sash fasteners of the ordinary type or of other suitable kinds as applied
to windows, the, attachment may also be successfully adopted in connection with 5
fasteners for other purposes than windows such as doors, etc. I will however
proceed to describe my invention with the aid of the drawings in reference to
windows as an illustration of my improved method.
Figure 1 is an elevation and Figure 2 a plan setting forth my improvements.
For my purpose I secure horizontally by screws or other means a steel spring
arm A. to the top of the inside meeting bar B. of the window sash. This spring
arm A. is connected at its one end with (or made integral with) a vertical piece,
bolt or peg C. which takes into a hole D. in the meeting bar B. made to receive
same. The position of this spring arm arrangement is immediately in front of
the arm E. of the window fastener when closed as shewn and the action is thus.
Given that the sash fastener unlocked as indicated by dotted lines, Figure 1
by turning the arm E. to lock same it passes over the spring arm A. and depresses
it the bolt or peg C. entering the hole D. as soon as the fastener is brought home
and locked in the usual manner the bolt or peg C. rises by the action of its spring
arm A and so, projecting above the meeting bar effectually prevents the arm of
the fastener E from being pushed back and unlocked until the combined spring A
with its peg C. is pressed down from the inside of the window as shewn by dotted
lines A when the sash fastener can be readily passed over it and into its open
position.
As will be understood my improved appliance can be readily adapted and
attached in connection with all existing window sash fasteners such as ordinarily
in use as an additional means of security or where arrangements will admit of
my system being employed as it is only necessary to bore a vertical hole in the
mid-horizontal bar and to fix the spring arm and bolt or 'peg in position.
For this and other purposes such as doors fanlights etc. the improved attach-
ment in connection with fasteners will be governed by the same principle above
described with slight variations as to detail to meet the requirements of individual
cases.
Having now particularly described and ascertained the nature of my said
invention. and in what manner the same is to be performed I declare that what
I claim is:
Firstly. In sash fasteners for windows the arrangement and combination of a
spring arm having a bolt or peg said bolt or peg being received in a vertical hole
in the mid-horizontal bar of the window frame and operating in manner and for
the purpose described.
Secondly. In combination with fasteners or fastenings for windows, doors and
the like purposes a spring arm having a bolt or peg thereon, working in a hole
or groove as described.
Thirdly. A spring attachment acting as an additional means of security in con-
nection with window and other fasteners, substantially as described.
