PROVISIONAL SPECIFICATION.
Improvements in Windows with Sliding Sashes.
THOMAS MARCUS HOUGHTON 139 Oxford Street London W., Quantity Surveyor
and THE GLOBE INVENTORS TRADING COMPANY LIMITED 11 Lincoln's Inn Fields,
W.C., do hereby declare the nature of this invention to be as follows:-
The object of this invention is to allow of the sashes being reversed so that
the external face of the glass may be cleaned from the inside.
The parting beads are made to terminate about at a level of the position of the
meeting rails i.e. leaving a space between the cill of the frame and the end of
the parting bead rather greater than the height of the top sash. The outside
lining is also cut back fair with the pulley style to about the same height the
stop bead to the pulley styles are omitted and a bead or molding may be worked
on the pulley styles on the inside linings for appearance and in continuation
of that to the head and the cill.
The sash lines are attached to the sashes by a hook or by passing through a
hole in a plate and knotted at about half their height and run in grooves in the
pulley styles instead of on the face of the same the sash pulleys being recessed
for that purpose. At about the centre of the height of the sashes projecting nibs
of metal are fixed which run up and down in the grooves by the sides of the lines
where they are attached to the sashes.
To the pulley styles hollow metal centres are fixed and the sashes (when in
the right position for the nibs before named to engage with same) will revolve
on these hollow centres or sockets so that they-the sashes-are inverted to an
angle of about 180 degrees but if it is desired to turn the sashes right over to
the 180° the head of the frame must be recessed about 3 inches so that the sashes
may be pushed up to clear each other when being inverted.
The nib before referred to may be made to partially clip and work on the hollow
socket as well as in it.
To form a weather joint of the bottom sash with the frame pocket pieces are
let into the pulley styles the height of the sash and projecting from the face of
the pulley styles about 5/8" shaped on their front faces the edge of the sash styles
being shaped out for them to work in these pocket pieces are kept forward by
either levers weights or, springs the sashes press them back into the pulley styles
when being turned on their centres.
The pocket pieces may be plated with metal on their backs and edges or both
or they may be entirely of metal.
A catch or stop is put to each pulley style for the bottom sash to prevent its
being moved on its centres excepting when required it is so shaped and attached
that on turning the sash back into its running position in the frame it strikes
the catches lifting them out of the way and when the sash has passed them they
fall and close it in automatically.
Dated this Fifth day of August 1896.

THOMAS MARCUS HOUGHTON 139 Oxford Street London W. Quantity Surveyor,
and THE GLOBE INVENTORS TRADING COMPANY, LIMITED, 11 Lincoln's Inn Fields,
W.C., 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 the
following statement:-
The object of this invention is to allow of the sashes being reversed so that
the external face of the glass may be cleaned from the inside. The parting beads
are made to terminate about at the level of the position of the meeting rails i.e.
leaving a space between the cill of the frame and the end of the parting bead
rather greater than the height of the top sash, the outside lining is also cut
back fair with the pulley style to about the same height the stop beads to the
pulley styles are omitted and a bead or a molding may be worked on the pulley
style or the inside linings for appearance and in continuation of that to the head
and cill.
"
The sash lines are attached to the sashes by a hook by passing through a plate
or a projecting nib at about half their height and they run in grooves in the
pulley styles of the frame instead of on the face of the same the sash pulleys
being recessed for that purpose.
These projecting nibs are made to revolve in plates which are fixed to the sashes
and run up and down in the grooves of the pulley styles.
To the pulley styles centres are fixed consisting of a hollow or grooved plate
of metal or centre and the sashes (when in the right position for the nibs before
named to engage with same) will revolve on the same so that they are inverted
to nearly 180° but if it is desired for the sashes to turn right over to the 180°
the head of the frame inust be recessed about three inches so that the sashes may
be pushed up for them to clear each other when being inverted.
The nib referred to may be fixed to and move with the sash and to revolve in
the hollow plate or centre and may be made to partially clip on the same as well
as in it for the purpose of preventing the sash from sliding up and down whilst
being reversed or a drop may be made to swing freely on the revolving nib so that
when the sash is in its right position for revolving or reversing the drop will
fall by gravity into a recess formed in the grooved plate of metal or centre and
the sash in revolving will hold it back in that position.
To form a weather joint of the bottom sash with the frame pocket pieces pre-
ferably of metal are let into or through the pulley styles the height of the sash
in two lengths to each side one being inside and the other outside to each style
viz.: four in all and they project from the face of the pulley style about 5/8" shaped
on their front faces or edges, the edges of the styles of the sash being worked
out for them to fit into, these pocket pieces or strips are kept forward by either
levers weights or springs and the sashes press them back into the pulley styles
out of the way when they are turned on their centres. The ends of the pocket
pieces or weather strips are shaped at their ends next the centres so that the sash
will strike, ride over and push the same back gradually and easily into the pulley
style. The top sash in revolving or reversing also strikes and presses back the
pocket pieces, both styles are bevilled off winding at their ends next the meeting 4
rail to effect the same purpose.
A catch or guide is put to the frame on both sides to prevent the bottom' sash
being reversed at any other than the right point for the centres.
In order that the said invention and the manner of performing or carrying the
same into effect may be properly understood we have hereunto appended an
.

page_text: explanatory sheet of drawings in which the same reference letters are employed to
indicate corresponding parts in all the figures where shewn.
Figure 1 is a sectional plan through the window A being the frame and half
of the sash above the meeting rail and B being the frame and half of the sash
below the meeting rail.
Figure 2 is a vertical section through the centre of the window.
Figure 3 is an enlarged plan of the style of the sash and pulley style below
the meeting rail with the pocket piece or strip fitting in same.
Figure 4 is the nib and the socket on which the sash revolves.
Referring to these drawings the letter C denotes the pulley styles D the
pocket pieces or strips E the outside linings parting beads G sash styles H
the catch or guide bars J the plate on style of frame through which the swinging
portion of the guide bar works K is the pivot which are the same to both top and
bottom sashes L is the fixed plate to the sash style for the pivot to revolve in M is
the groove in the pulley styles for the guide bar and sash line N to work in.
P P are the springs which act on the pocket pieces or strips D, they may be
about an inch wide, two to each strip across the strip as shewn or lengthways at
each end.
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:
First The general arrangement construction and combination of the various
parts constituting our improved reversible window that the sashes of the same
may be turned over on centres substantially as hereinbefore described and shewn
on the accompanying drawings.
Second The sliding nib and plate centres substantially as herein before
described and shewn on the accompanying drawings.
Third. The bent or shaped on edge pocket pieces or strips working in the
styles of the sashes as weather fillets guards and guides in place of the parting
and stop bead to the bottom sash substantially as hereinbefore described and
shewn on the accompanying drawings.
