IMPROVEMENTS IN SLIDING WINDOW SASHES
Year: 1884

page_text: I JAMES DUNNING TUCKER of Bromley in the County of Kent House Decorator
do hereby declare the nature of my said Invention for IMPROVEMENTS IN SLIDING
WINDOW SASHES, to be as follows:-
My Invention relates to sliding window sashes and has for its object the fitting
of the same in such a manner as to exclude wind and dust and rain and weather
and to prevent the sashes rattling and shaking or creating any noise when the
window is shut. My Invention also prevents these sashes being opened from the
outside.
To carry out this object I plough a groove lengthwise out of the vertical side
stiles of the sashes on those sides thereof that face the parting bead. This groove
may be made of any shape in cross section either rectilinear or semicircular or
curved in any manner as may be desired. The parting bead is made rather
broader than is usual and it is so shaped in cross section as to fit into these
ploughed grooves in the sashes on either side. The parting bead may be made
either of wood or of metal and instead of being let into a groove in the pulley stile
as is usual it is secured thereto on the face of the same by screws or other
fastenings. I prefer to make the pulley stile rather stouter than is usual to ensure
the parting bead being firmly secured thereto. The bottom rail of the lower sash
and the top rail of the upper sash have also grooves ploughed in them on their
bottom and top faces respectively in which grooves I secure pieces of india rubber
or other elastic material preferably of a tubular shape which pieces extend the
whole length of the rails and project a little beyond the faces of the same and when
the sashes are closed press against the window sill at the bottom and the window
head at the top of the frame in which parts also I may make shallow hollows or
grooves into which hollows or grooves the projecting parts of the pieces of india
rubber may enter and exclude wind dust rain and weather while at the same time no
noise is created when the window is closed. The meeting rails of the sashes that
is to say the top rail of the lower sash and the bottom rail of the upper sash have
bevelled meeting faces in which bevelled faces at or about the centres thereof
I form elbows or angles lengthwise in the faces corresponding to each other and in
one of these elbows or angles preferably in that on the lower sash I plough a groove
in which groove also I secure a piece of india rubber or other elastic material
preferably of a tubular shape which piece extends the whole length of the rail and

against the corresponding elbow on the other sash in which corresponding elbow I
may also make a shallow hollow or groove into which hollow or groove the
projecting part of the piece of india rubber may enter and exclude wind dust rain
and weather while at the same time no noise is created when the window is closed.
This elbow or angle in the bevelled meeting faces also prevents the window being
opened from the outside as no instrument can be passed up between the sashes to
move or unlock the fastening thereof. The sliding sashes are hung or suspended
in the usual manner or as may be most convenient and they run more freely and
casily than the ordinary sashes as the parting bead being engaged in the grooves
of the side stiles of the sashes, acts as a guide therefor when the same are opened
or closed and obviates the necessity of fitting the sashes so tightly in between the
opposite pulley stiles of the window frame while at the same time rattling or
shaking of the sashes is prevented and wind dust rain and weather are excluded.

I JAMES DUNNING TUCKER of Bromley in the County of Kent, House Decorator
do hereby declare the nature of my said Invention for IMPROVEMENTS IN SLIDING
WINDOW SASHES and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My Invention relates to sliding window sashes and has for its object the fitting
of the same in such a manner as to exclude wind and dust and rain and weather
and to prevent the sashes rattling and shaking or creating any noise when the
window is shut. My Invention also prevents these sashes being opened from the
outside.
In order to explain my Invention and in what manner the same is to be
performed I refer to the accompanying Drawing.
Figure 1 is a vertical transverse section of a window fitted and constructed
according to this my Invention. Figure 2 is an horizontal transverse section of the
same taken at a. b. in Figure 1. Figure 3 is an horizontal transverse section of
the same taken at c. d. in Figure 1.
A is the ordinary window frame in which the sashes slide and to carry out my
aforesaid object I plough grooves lengthwise in the vertical side stiles B of the
sashes on those sides thereof that face the parting bead C which grooves may be
shaped in cross section as is hereinafter described. The parting bead C is made
rather broader than is usual and it is so shaped in cross section as to fit into the
aforesaid ploughed grooves in the stiles B of the sashes on either side. I shew in
the Drawing three shapes or forms of the aforesaid parting bead and grooves
therefor. In Figure 2 the groove B' and that part C¹ of the bead C that fits
thereinto is semicircular in sectional shape and the groove B² and that part C³ of

page_text: the bead C that fits thereinto is rectilinear or angular in sectional shape. In
Figure 3 the bead C³ is bulbous or circular and the groove B³ is made accordingly.
I consider that these shapes as shewn are the best and most suitable for my
purposes as herein declared but I do not limit myself thereto for the said ploughed
grooves and those parts of the bead that fit thereinto may be made of any sectional
shape that may be convenient or desirable in each case. The parting bead C may
be inade of wood or of metal and instead of being let into a groove in the pulley
stile D as is usual the said bead C is secured to the said stile D on the face thereof
by screws or other similar fastenings as shewn in the Drawing and to ensure the
firmness and security thereof it is preferable to make the said stile D rather
stouter than is usual.
I also plough grooves in the lower face of the bottom rail E of the lower sash
and in the upper face of the top rail F of the upper sash in which grooves are
secured pieces of india rubber or other material G preferably of a tubular shape as
shewn and elastic and compressible which said pieces G extend the whole length of
the said rails E and F or the whole breadth of the sashes and project a little
beyond the aforesaid faces thereof so that when the sashes are closed the said
pieces G press against the window sill A¹ at the bottom and the window head A*
at the top of the frame A in which said parts A¹ and A2 also I preferably make
shallow hollows or grooves into the which the projecting parts of the said pieces G
may enter as shewn in the Drawing and thus and in this manner the entrance of
wind and dust and rain and weather is entirely prevented while at the same time
when the said pieces G are made of india rubber or elastic compressible material no
noise is created when the window is shut.
The meeting rails of the sashes that is to say the top rail H of the lower sash
and the bottom rail K of the upper sash have bevelled meeting faces in which
bevelled faces at or about the centres in a vertical direction thereof I form elbows
or angles corresponding to each other lengthwise the whole breadth of the sashes
and in one of these said elbows or angles preferably in that on the rail H of the
lower sash I may plough a groove in which groove is secured a piece of india
rubber or other material L preferably of a tubular shape as shewn and elastic and
compressible which said piece L extends the whole length of the said rail H or K
and projects a little beyond the face of the aforesaid elbow or angle therein so that
when the sashes are closed the said piece L presses against the corresponding elbow
or angle on the rail K or H of the other sash in which said corresponding elbow or
angle also I may make a shallow hollow or groove into the which the projecting
part of the said piece L may enter as shewn in the Drawing and thus and in this
manner the entrance of wind and dust and rain and weather is entirely prevented
while at the same time when the said piece L is made of india rubber or elastic
compressible material no noise is created when the window is shut. The aforesaid
elbow or angle in the bevelled meeting faces also prevents the window being
opened from the outside as no instrument can be passed up between the sashes to
move or unlock the fastening thereof.
The aforesaid pieces of india rubber or other material G and L may be secured
in position in any convenient and suitable manner and when the said pieces G
and L are elastic they can preferably be compressed into their respective grooves.
The sliding sashes may be hung or suspended in the usual manner by the cords M
and counterbalanced by the weights N attached thereto or otherwise as may be
most convenient and these sashes so fitted and constructed as hereinbefore described
run more freely and easily than do the ordinary sashes as the parting bead being
engaged in the grooves in the side stiles of the sashes acts as a guide therefor when
the said sashes are opened or closed and thus the necessity of fitting the sashes so
tightly as is usual between the opposite pulley stiles is obviated while at the same
time any rattling or shaking of the sashes is prevented.
I have thus described and shewn in the accompanying Drawing what I consider
to be the best methods of carrying out my Invention and of attaining my object
as herein before declared but I would have it understood that I do in no wise limit

page_text: myself to the exact shapes and details of construction as so described and shewn
for the same may be altered and varied as may be most convenient or desirable in
each particular case without departing from this my Invention.
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 sliding window sashes constructed and fitted substantially as hereinbefore
described and set forth and shewn in the accompanying Drawing.
2. The vertical grooves in the side stiles of sliding window sashes and the
parting bead that engages therein substantially as hereinbefore described.
3. In sliding window sashes the combination of the parting beads C the vertical
grooves B and the pieces G substantially as and for the purposes hereinbefore set
forth.
4. In sliding window sashes the combination of the parting beads C the
vertical grooves B and the bevelled elbowed meeting faces of the rails H and K
with or without the piece L substantially as and for the purposes hereinbefore set
forth.
5. In sliding window sashes the combination of the parting beads C the vertical
grooves B the bevelled elbowed meeting faces of the rails H and K with or without
the piece L and the pieces G substantially as and for the purposes hereinbefore set
forth.
