County of Middlesex, Carpenter and Joiner do hereby declare the nature of my
Invention for "IMPROVED DEVICE FOR PREVENTING THE RATTLING OF WINDOW
SASHES to be as follows:-
"
The object of my Invention is to provide suitable means for preventing the
rattling of window sashes, and also to furnish by the same means, an additional
security against such sashes being opened from the outside.
My invention consists of two small levers secured to the beads on each side of
the sash in such a manner that the short end of the lever acts as an eccentric, and
when the long end of the lever is moved away from the sash the short end thereof
presses the sash against the parting bead, and also presses the meeting bars
together and prevents the sashes from rattling. When the sash is thus fixed all
tampering with the window from the outside is frustrated & any attempt to open
the window increases its security.
The lever or fastening is constructed in such a manner that the short end is
heavier than the long end, and when it is free from the sash the long end points.

and upon which screw it works freely. The fastening is made of brass, iron, hard
wood, or other suitable material, and may be applied to all sashes, railway carriage.
windows, and windows of broughams and other carriages.
In cases where the meeting bars are not carefully made, I sometimes add a link
to my said fastener, which link is fastened or hooked to the upper sash, bar, and,
the lever falls over the lower sash bar, against which the eccentric impinges, and
this secures both sashes against rattling.

I ALFRED BRADLEY JOHNSON of 50 (late 35) Kingsgate Road, Hampstead, in
the County of Middlesex Carpenter and Joiner do hereby declare the nature of
my said Invention for "IMPROVED DEVICE FOR PREVENTING THE RATTLING OF
WINDOW SASHES" 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 my invention is to provide suitable means for preventing the
rattling of window sashes, and also to furnish by the same means, an additional
security against such sashes being opened from the outside."
My invention consists of 2 small levers secured to the beads on each side of the
sash in such a manner that the short end of the lever acts as an eccentric, and,
when the long end of the lever is moved away from the sash the short end thereof
presses the sash against the parting bead and also presses the meeting bars together
and prevents the sashes from rattling. When the sash is thus fixed all tampering
with the window from the outside is frustrated and any attempt to open the
window increases its security.
The lever or fastener is usually constructed in such a manner that the short end
is heavier than the long end, and when it is free from the sash the long end points
vertically upwards, the centre upon which it works consisting of a screw, which is
screwed into the bead; and upon which screw it rotates freely. The fastening is
made of brass, iron, hardwood, vulcanite or other suitable material, and may be
applied to all sashes, railway carriage windows, and windows of broughams, and
other carriages.
And in order that my said invention may be clearly understood, reference is
hereby made to the accompanying drawings, in which similar letters of reference
indicate corresponding parts.
In the figures a is the inner bead of the window, b is the outer bead, c is the
parting bead, d is the upper bar of the lower sash (in section) and e is the lower
bar of the upper sash (in section). f is my improved fastener, fitted to the bead a
by the screw g.
In Fig. 1 the two sash bars d and e are shewn separated by the space h, the
fastener being disengaged and free from the sash bar. In Fig. 2 the fastener is
shewn in use, pressed against the sash bar d, which bar is in turn pressed against
the sash bar e, as shewn. One fastening is required on each side of the sash in
order to press the sash bars together and prevent the same from rattling. d¹ is a
metallic plate screwed to the sash stile to prevent it from being damaged by the
pressure of the fastening.
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. The manufacture and use of window sash fastenings applied and operating
substantially as and for the purposes hereinbefore described and shewn on the
drawings.
2. The method of preventing the rattling of windows by means of rotating levers
having an eccentric action substantially as hereinbefore described and shewn on the
drawings.
