and in the hollow or box of the arm or lever a flat or blade spring is placed the
end of the said spring nearest the joint or centre of the arm or lever being fixed.
At about the middle of the flat or blade spring a stud or bolt is situated. This
stud or bolt passes through a hole in the upper face of the arm or lever and in its
normal position projects a short distance above the said arm or lover. The upper
end of the stud or bolt is slightly inclined. The axis of the handle of the arm or
lever is hollow or tubular and in the hollow part of the handle a rod or pusher
works its lower end bearing upon the free outer end of the flat or blade spring.
In the underside of the "quadrant" or hook under which the jointed arin or
lever passes to fasten the sashes is a hole or depression of a size suitable for the
stud or bolt on the flat or blade spring to take into.
When the jointed arm or lever is turned on its joint in the direction proper for
fastening the sashes the spring stud or bolt is depressed by its inclined end
travelling against the underside of the "quadrant" or hook and when the jointed
arm or lever has reached its fastening position the said stud or bolt is brought
under and snaps into the hole or depression in the quadrant or hook thereby
automatically locking the arm or lever in its fastening position.
In order to unlock the arm or lever for unfastening the sashes the rod or pusher
in the handle of the arm or lever is pressed down.
The flat or blade spring is thereby depressed and the stud or bolt carried by it
withdrawn from the hole or depression in the "quadrant" or hook. The arm or
lever is thus unlocked and may be turned aside for unfastening the sashes.

We ROWLAND HODGES of N° 12 Frederick Street, Birmingham in the County
of Warwick, Brassfounder and JOHN ARCHER of the Hollies, Yardley Road,
Birmingham aforesaid Brassfinisher, do hereby declare the nature of the Invention
for "AN IMPROVEMENT OR IMPROVEMENTS IN SASH FASTENINGS 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 effect the automatic locking of the jointed arm
or lever of the sash fastening, when the said arm or lever is turned into its
fastening position and thereby prevent the pushing back of the said arm or lever
and the unfastening of the sashes by means of a knife or other instrument intro-
duced between the sashes from the outside of the window.
This object is effected in a simple and efficient manner by the construction and
combination of parts herein after described.
The jointed arm or lever of the sash fastening is made hollow or of a box form
and in the hollow or box of the arın or lever a flat or blade spring is placed the
end of the said spring nearest the joint or centre of the arm or lever being fixed.
At about the middle of the flat or blade spring, a stud or bolt is situated. This
stud or bolt passes through a hole in the upper face of the arm or lever and in its
normal position projects a short distance above the said arm or lever. The upper
end of the stud or bolt is slightly inclined. The axis of the handle of the arm or
lever is hollow or tubular and in the hollow part of the handle a rod or pusher
works its lower end bearing upon the free outer end of the flat or blade spring.
In the underside of the "quadrant or hook under which the jointed arm or lever
passes to fasten the sashes is a hole or depression of a size suitable for the stud or
bolt on the flat or blade spring to take into.
When the jointed arm or lever is turned on its joint in the direction proper for
fastening the sashes, the spring stud or bolt is depressed by its inclined end
travelling against the underside of the "quadrant" or hook and when the jointed
arm or lever has reached its fastening position the said stud or bolt is brought
under and snaps into the hole or depression in the quadrant or hook thereby
automatically locking the arm or lever in its fastening position.
In order to unlock the arm or lever for unfastening the sashes the rod or pusher
in the handle of the arm or lever is pressed down.
The flat or blade spring is thereby depressed and the stud or bolt carried by it
withdrawn from the hole or depression in the "quadrant" or hook. The arm or
lever is thus unlocked and may be turned aside for unfastening the sashes.
Figure 1 of the accompanying Drawing represents in side elevation; Figure 2
in plan and Figures 3 and 4 in section (the said sections being taken at right
angles to one another) a sash fastening constructed according to this invention, the
jointed arm or lever being in its fastening position and locked by the mechanism
constituting this invention: Figure 5 represents the spring stud or bolt of the
fastening disengaged from the quadrant for unfastening the arm prior to turning it
aside and Figure 6 represents the same after it has been turned aside for unfastening
the sushes; Figure 7 represents a plan of underside of the quadrant,

page_text: The same letters of reference indicate the same parts in the several Figures of
the Drawing.
a is one part of the sash fastening fixed to the meeting rail b on the upper sash
and o is the other part of the sash fastening fixed to the meeting rail d of the
lower sash; e is the jointed arm or lever on the part a of the fastening and ƒ is
the "quadrant" on the part o of the fastening, under which quadrant the jointed
arme passes to fasten the sashes. The jointed arm e is hollow or of a box form
and contains the flat or blade spring 7 fixed at one end to the said arm. The
middle of the flat or blade spring g has fixed to it an inclined stud or bolt & which
projects in its normal state through a hole in the upper face of the said arm e.
The handle i of the jointed arm e is hollow or tubular and in the said hollow
handle a rod or pusher works the lower end of the said rod or pusher bearing
upon the free end of the flat or blade spring g which spring raises the said pusher
into the position represented. The said rod or pusher is kept in its place in the
handle by a collar under the head of the pusher bearing against the turned in edge
or top of the handle i.
The quadrant has a cross depression 7 made in its underside of a size suitable
for the stud or bolt h to engage with.
When the jointed arm or lever e is in the fastening position, Figures 1. 2. 3 and 4,
the spring stud or bolt h is engaged with the cross depression in the quadrant f
and the said jointed arm is bolted or locked in its place. As the jointed arm e is
turned on its joint for taking the fastening position the spring stud or bolt h which
is situated above the face of the arm is depressed by its inclined projecting end
travelling against the convex underside of the quadrant f and when the said
jointed arm e has reached the fastening position Figures 1. 2. 3 and 4 the said stud
or bolt h is brought under and snaps into the depression in the quadrant (see
Figures 3 and 4) and thereby automatically locks or bolts the said arm e in its
fastening position and the unfastening of the sashes by a knife or instrument
introduced between the sashes from the outside of the window is prevented.
Before the arm or lever e can be turned aside for unfastening the sashes the stud
or bolt h must be released from the depression in the quadrant f. This is effected
by pressing down the rod or pusher k into the position represented in Figure 5.
The flat or blade spring g is thereby depressed and the stud or bolt h withdrawn
from the depression in the quadrant as represented in the said Figure 5. The
unlocked jointed arm e may now be turned aside into the position Figure 6 for
unfastening the sashes. On removing the pressure from the rod or pusher k it is
returned to its normal position by the spring g.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is
Automatically locking or bolting the jointed arms or levers of sash fastenings in
their fastening position by means of the flat or blade spring g carrying the inclined
stud or bolt h the said stud or bolt taking into a depression in the quadrant and
releasing the said stud or bolt h from the quadrant, prior to the unfastening of the
sashes, by means of the rod or pusher k acting upon the spring of the said bolt or
stud, the several parts being combined and operating substantially as herein before
described and illustrated in the accompanying Drawing.
