We DEBORAH GLAISTER of 18 St Mary's Terrace Ryton in the County of
Durham Widow and EDWIN GLAISTER of the same place Commercial Traveller
the legal personal representatives of Jacob Glaister deceased late of 6 South
Avenue Ryton aforesaid Clerk of Works do hereby declare the nature of this
Invention to be as follows:-
This Invention has for its object to so construct and connect the parts of
moveable partitions window shutters window sashes and the like that by moving
one of the sashes of a window or one part of a moveable partition or the like in
one direction the other sash of the window or another part of the moveable partition
or the like will be caused to move in the opposite direction as hereinafter fully
described.
According to this Invention the partition or screen consists of a frame at the
upper part of which may be fixed a panel glazed frame or sash and at the lower
part a fixed panel or cleading surmounted by a cill or an opening in the floor
according to the purpose to be fulfilled.
Between the fixed sash and the cill are fitted to slide sashes arranged vertically
one above the other and capable of being slidden in grooves provided in jambs
forming the sides of the frame in which the sashes slide and which should be as
long as the distance the sashes may be required to slide.
On the face of each jamb two strips are fixed so as to form a groove or recess
within which the sashes may slide both sashes preferably sliding in the same
grooves or recesses. These grooves or recesses may however be constructed in any
other way desired so long as they do not interfere with the movements hereinafter
described. A dividing space is made through each jamb of sufficient width and
length to enable a bracket attached to the lower sash to move up and down with
the sash.
The two sashes when closed meet and should fit closely one against the other and
should be of about equal weight so as to approximately balance one another when
connected as hereinafter mentioned the upper sash by preference slightly exceeding
in weight the lower sash. If desired the contiguous edges of the sashes may be
tongued and grooved or provided with a strip of india rubber or the like so as to
form a dust and draught proof jamb when the sashes are closed.

page_text: The sashes are suspended by two cords or ropes arranged one on each side and
passing over pulleys fitted in the jambs and descending in grooves or recesses in
the said jambs. These cords or ropes are fastened at one end in recesses in the
upper sash and their opposite ends are connected to the brackets fixed to the lower
sach the said cords or ropes thus forming a connection between the two sashes.
The brackets project through the pulley jambs into the recesses and the connection
of the cords or ropes therewith is preferably made at each side by means of a screw
bolt and nut to which bolts the cord or rope is fastened and by which the cords or
ropes may be tightened as required. The position of the pulleys and the brackets
and the length of the cords or ropes must be calculated and determined by the
distance through which the sashes are required to slide. Doors may be provided
in the architraves to afford easy access to the screw bolts and nuts for the purpose
of adjusting the length of the cords or ropes when required.
On one or both sides of the upper sash a rack may be fixed to engage a spring
catch or bolt fixed in the pulley jambs for the purpose of retaining the sashes in
any desired position the said spring catch or bolt being for the purpose of opening
the sashes disengaged from the rack by pulling a cord or rope provided for the
purpose.
To each bracket before mentioned is attached a strip of wood or metal fitted to
slide in a groove in the back of the jambs and extending upwards so as to cover
the dividing spaces in the jambs through which the brackets move when the sashes
are opened; the said strips being of sufficient length to completely protect the
whole length of the dividing spaces when the bottom sash is lowered to its full
extent and thus prevent the entrance or introduction of materials or articles that
would interfere with the proper working of the sashes.
The sashes and frame work may be made of any suitable material such as glass
iron or wood and provision may be made for the free sliding of the sashes to any
required height and depth and if necessary a case of wood or metal may be
provided below the floor of a room for the reception of the lower sash so as to
leave an unobstructed floor area.
To open the sashes the spring bolt or bolts is or are first disengaged from the
rack or racks and then by exerting a very high pressure upon the sash in an
upward direction or upon the sash in a downward direction for example both
sashes will be caused to slide simultaneously in opposite directions preferably the
upper sash towards the top of the frame and the lower sash downwards into the
recess in the panel or cleading.
This Invention is applicable to the windows, doors window shutters and sides of
rooms of private houses factories public halls and the like and is specially adapted
for the purposes of temporarily partitioning rooms or halls into compartments
and of affording a thorough and speedy method of ventilation in schools and work-
shops and when the partitions are made of glass of affording a ready means of
combining in a school the advantages of a large Hall for united exercises with those
of separate class rooms.

We DEBORAH GLAISTER of 18 St Mary's Terrace Ryton Durham, Widow, and
EDWIN GLAISTER of the same place Commercial Traveller (the legal personal
representatives of Jacob Glaister deceased, late of 6 South Avenue, Ryton afore-
said, Clerk of Works) 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 by the following statement :-
This Invention has for its object to so construct and connect the parts of
moveable partitions, window shutters, window sashes, and the like, that by
moving one of the sashes of a window or one part of a moveable partition or
the like in one direction the other sash of the window or another part of the
movable partition or the like will be caused to move in the opposite direction as
hereinafter fully described.
We will describe this invention with reference to the accompanying drawings
Figure 1 of which represents in front elevation a portion of a window or glazed
partition or screen constructed according to this invention. Figure 2 is a
transverse vertical section of the same Figure 3 is a horizontal section (drawn
to a larger scale) taken along the line 1, 2. in Figure 1. Figure 4 is a detail
hereinafter described.
According to this Invention the partition or screen consists of a frame A at the
upper part of which may be fixed a panel, glazed frame, or sash B, and at the
lower part a fixed panel or cleading C, surmounted by a cill D, or an opening in
the floor according to the purpose to be fulfilled.
Between the fixed sash B and the cill D, are fitted to slide sashes E and F
arranged vertically one above the other and capable of being slidden in grooves
provided in jambs a forming the sides of the frame A in which the sashes slide
and which should be as long as the distance the sashes may be required to slide.
On the face of each jamb a two strips b are fixed so as to form a groove or
recess c within which the sashes may slide, both sashes preferably sliding in the
same grooves or recesses. These grooves or recesses may however be constructed
in any other way desired so long as they do not interfere with the movements
bereinafter described. A dividing space d is made through each jamb a of
Bufficient width and length to enable a bracket attached to the lower sash to move
up and down with the sash.
:
The two sashes E and F when closed meet, and should fit closely one against the
other, and should be of about equal weight so as to approximately balance one
another when connected as hereinafter mentioned, the upper sash E by preference
slightly exceeding in weight the lower sash. If desired the contiguous edges of
the sashes may be tongued and grooved or provided with a strip of india rubber or
the like so as to form a dust and draught proof joint when the sashes are closed.

page_text: The sashes E and F are suspended by two cords or ropes e arranged one on each
side and passing over pulleys ƒ fitted in the jambs a and descending in grooves or
recesses in the said jambs. These cords or ropes are fastened at one end in recesses
in the upper sash E and their opposite ends are connected to the brackets H fixed
to the lower sash F, the said cords or ropes thus forming a connection between the
two sashes. The brackets H project through the pulley jambs a into the recesses a³
as shewn in Figure 3 and the connection of the cords or ropes e therewith is
preferably made at each side by means of a screw bolt G and nut g, to which bolts
the cord or rope e is fastened, and by which the cords or ropes may be tightened
as required. The position of the pulleys f and the brackets H, and the length
of the cords or ropes e, must be calculated and determined by the distance
through which the sashes are required to slide. Doors h may be provided in
the architraves as shewn in Figures 1 & 3 to afford easy access to the screw
bolts G and nuts g for the purpose of of adjusting the length of the cords or ropes
when required.
On one or both sides of the upper sash E a rack I may be fixed as shewn in
Figures 1 and 4 to engage a spring catch or bolt K fixed in the pulley jambs a for
the purpose of retaining the sashes in any desired position, the said spring catch or
bolt, for the purpose of opening the sashes, being disengaged from the rack I by
pulling a cord or rope i provided for the purpose as will be clearly understood by
reference to the enlarged detail Figure 4.
To each bracket H is attached a strip k of wood or metal fitted to slide in a
groove in the back of the jambs a and extending upwards so as to cover the
dividing spaces d in the jambs through which the brackets H move when the
sashes are opened and closed; the said strips being of sufficient length to
completely protect the whole length of the dividing spaces when the bottom
Bash F is lowered to its full extent and thus prevent the entrance or introduction
of materials or articles that would interfere with the proper working of the sashes.
The sashes and frame work may be of any suitable material, such as glass iron
or wood and provision may be made for the free sliding of the sashes to any
required height and depth and if necessary a case of wood or metal may be
provided below the floor of a room for the reception of the lower sash so as to
leave an unobstructed floor area.
To open the sashes the spring bolt or bolts K is or are first disengaged from the
rack or racks I and then by exerting a very slight pressure upon the sash E in an
upward direction or upon the sash F in a downward direction for example both
sashes will be caused to slide simultaneously in opposite directions preferably the
upper sash E towards the top of the frame A and the lower sash F downwards
into the recess in the panel or cleading C.
This Invention is applicable to the windows, doors, window shutters and sides
of rooms of private houses factories public halls and the like, and is specially
adapted for the purposes of temporarily partitioning rooms or halls into com-
partments, and of affording a thorough and speedy method of ventilation in
schools and workshops.
When the partitions are made of glass they afford a ready means of combining
in a school the advantages of a large hall for united exercises with those of
separate class rooms.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is :-
First. Partitions, doors, window sashes, shutters and the like formed in separate
parts and having in combination therewith means whereby when one of the parts
is moved the other is simultaneously moved in the opposite direction substantially
as herein before described and illustrated in the accompanying drawinga.
Second Partitions, doors, window sashes, shutters and the like formed in
separate parts connected by cords ropes or the like so that when one part is

page_text: moved the other part is simultaneously moved in the opposite direction and
having in combination therewith either any or all of the following means; namely
means for excluding dust, means for adjusting the length of the cords or ropes and
means for securing and retaining the parts of the sash or the like in position
all substantially as hereinbefore described and illustrated in the accompanying
drawings.
