page_text: improvements in, wedges to Frevent the Kattling of Sashes.
I, WILLIAM HENRY WAKFER, of 16, Hermitage Road, Green Lanes, in the County
of Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to wedges to prevent the rattling of the sashes.
I make the wedge preferably of sheet or cast metal and I provide it with a flap
or extension having a slot. This slot is intended for a screw or the like and con-
stitutes the means of attachment to the sash or other part to which the wedge is
generally screwed. The slot allows of giving a certain amount of motion to the
wedge so that the latter may be fixed between the window sash and its frame when
in one position and perfectly clear of same when in the opposite position. In order
to facilitate the handling of the wedge it is provided with a lug or turned up part
to lay hold of. The wedge part may either be made hollow or solid and preferably
the parts in wedging contact with the woodwork of the window are made rounded
so as not to scratch or mark the paint.
The wedge may also to a certain extent serve as a sash fastener to prevent the
window from being opened or to retain it at any desired position.

I, WILLIAM HENRY WAKFER, of 16, Hermitage Road, Green Lanes, in the County
of Middlesex, Engineer, do hereby declare the nature of this invention and in what
manner the same is be performed to be particularly described and ascertained
in and by the following statement:-
-
My invention relates to wedges to prevent the rattling of sashes.

Referring to Figures 3 and 4 it will be seen that I make the wedge of a straight
part A. and a lent part A¹ preferably of sheet or cast metal and I provide it with a
Hap or extension B having a slot C. This slot is intended for a screw D or the like
and constitutes the means of attachment to the sash or other part to which the 1
wedge is generally secured. The slot allows of giving a certain amount of motion
to the wedge A. A¹ so that the latter may be fixed between the window sash E and
its frame F, shown in dotted lines see Figure 2 when in one position and perfectly
clear of same when in the opposite position as shown in full lines in Figure 2. The
slot is conveniently provided with serrations or the like as shewn in Figure 3 which
catch more or less on the screw D and prevent the wedge being too easily displaced,
but these serrations are not absolutely essential. In order to facilitate the handling
of the wedge it is provided with a lug G or turned up part to lay hold of. The
wedge part A A¹ may either be made hollow as shown or solid and preferably the
parts in wedging contact are made rounded so as not to scratch or mark the paint
on the sashes or frames or the wedge part or parts may be more or less covered with
india rubber or other material for the purpose of preventing the scratching of the
paint or the like.
Figures 5, 6 and 7 shew a hollow wedge made of stamped or cast metal with a
wedge part A2, two flaps or extensions B1, B2 to lie flat on the side of the sash,:
slots CC for screws or studs D₁ Ds and lugs G G². Figure 1 shews the wedge
applied to the middle of the lower sash but it is of course applicable to any con-
venient part of a sash.
Figures 8, 9 and 10 show a double wedge that is to say there are really two
wedges A3 and A4 mounted on a common base plate B³ with a serrated slot C³,
transverse slot C screw D³ and lug G³. The wedge part A³ which projects upwards
above the level of the base plate B³ takes in between the parting bead and the
upper sash and the wedge part A takes between the lower sash and the frame as
shown on the left hand side of Figures 1 and 2. The transverse slot C is for
allowing of the double wedge to be withdrawn clear of the sashframe F and parting
bead H.
The construction of double wedge shown in Figures 11 and 12 is very much the
same as that shewn in Figures 8, 9 and 10 except that the wedge part A5 is bent
up in the same way as is A4 and not down as is A³ in the before mentioned figures.
Figures 13 and 14 illustrate a simple form of wedge for holding the two sashes
that is to say the wedge is attached by a screw to the lower sash while the wedge
part A jams the upper sash away from the parting bead H¹. The slot C5 in the
flap or extension B provides for holding the upper and lower sashes together when
the wedge is in action and the slot C at right angles to the slot C5 allows of the
wedge being drawn clear of the upper sash. The flap or extension B4 is provided
with a lug G for the purpose of laying hold of.
The wedges described may also to a certain extent serve as sash fasteners to
prevent the window from being opened or to retain it at any desired position.
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:-
1. A wedge to secure or prevent the rattling of a window sash consisting of a
wedge part and a flap or extension provided with a slot for a screw or the like to
limit the motion of the wedge substantially as described and shewn.
2. A wedge to secure or prevent the rattling of a window sash consisting of a
wedge part A A¹ a flap or extension B having a slot C for a screw or the like and

page_text: a lug G substantially as described and shewn with reference to Figures 1, 2, 3 and 4.
3. A wedge to secure or prevent the rattling of a window sash consisting of a
wedge part A2, two flaps or extensions B¹ and B3 having slots D1 and D2 respectively
for screws or the like and lugs G¹ and G2 substantially as described and shewn with
reference to Figures 1, 5, 6 and 7.
4. A double wedge to secure or prevent the rattling of the upper and the lower
window sashes consisting of two wedge parts, a flap or extension B³ having a slot C³
for a screw or the like, a transverse slot C and a lug G³ substantially as described
and shewn with reference to Figures 9, 10, 11 and 12.
5. A wedge to secure or prevent the rattling of the upper and lower window
sashes consisting of a wedge part a flap or extension B4 having a slot C5 for a screw
or the like, a transverse slot Co and a lug G substantially as described and shewn
with reference to Figures 13 and 14.
