Improvements in and connected with Window Sashes.
I, CHARLES ERNEST HADLOW, of Sand Rock Hill, Haslemere, Surrey, Gentle-
man, do hereby declare the nature of this invention to be as follows:--
My invention relates to improvements in window sashes, the object being to
construct and arrange them in such a manner that the house can always be
ventilated without fear of the entrance of wet or burglars by leaving the house
with the windows slightly open, while a room can be ventilated without draught,
moreover weights are dispensed with which effects a saving in the cost of con-
struction, while no lines are employed, chains being utilized to replace these, and
the sashes are further arranged in such a manner as to be readily removable,
while a fastener of improved form is arranged at the bottom of the window instead
of at the meeting rails which securely fastens the sashes in either the opened or
closed positions.
In carrying my invention into practical effect, the sashes run in grooves in
the frame, so that beads are entirely dispensed with, while the ordinary cords and.
weights are not employed, the outside sash being secured to the inside one upon
each side by a chain secured at each end to the two window sashes and passing
over suitably arranged pulleys at the top of the window frame, these chains
being secured to the sashes by small hooks or eyes engaging with a fixed pin on
the sash.
The pulley style of the frame is solid upon one side while upon the other
it is furnished with two pocket pieces extending more than half way up, and
which are fastened in place by being dropped into a mortice in the sill and
having a flush bolt at the top which engages with the solid part of the pulley
style.
By drawing back this bolt the inner pocket piece can be removed leaving the
sash free to swing into the room, the chain can then be unhooked and secured
to the pin upon the lower part of the outer sash, while upon releasing the other
side of the sash it is quite free for cleaning purposes or otherwise, and the outer
sash is left suspended. Upon the second pocket piece being removed the outer
sash can be taken out in a similar manner.
By the connection of the sashes with chains passing over suitably arranged
pulleys, it is obvious that when the inner sash is raised the outer one comes down
or is opened. Now for purposes of ventilation the inner sash is raised say four
or five inches and a suitable strip or piece of wood which is hung upon butt
hinges on the sill is raised and the sash closed down upon it where it is secured
in position by the fastening device hereinafter described. In this manner the
window is open at the..top for the escape of the hot,air while the space between
the inner and outer sashes serves for the admission of fresh air, while owing
to the two sashes being connected, the parts are all locked in this position by the
aforesaid fastening device.
The fastening device comprises. a circular hook pivoted to a plate at the bottom
of the sash and furnished with a knob or handle which acts as a balance .weight

page_text: keeping the fastener either in the opened or closed position according as required,
while the catch of the fastener comprises a plate furnished with two slots into
one of which the end of the catch enters passing out at the other and this plate
is let flush into the window sill and screwed down, a similar plate being let
into the ventilating piece which supports the window sashes when opened for
ventilating purposes, and by this means they can be secured in either the open
or closed position.
The sliding slips which are secured to the sashes and which take into the
grooves in the frame, preferably extend the full length of the sashes, and are
covered with zinc or other suitable material, while a suitable weather board secured
to the top and outside the frame is provided to prevent the entrance of rain and
also to break the force of the wind when the window is opened.

Improvements in and connected with Window Sashes.
I, CHARLES ERNEST HADLOW, of Sand Rock Hill, Haslemere, Surrey, Gentle-
man, 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;-
My invention relates to improvements in window sashes, the object being to
construct and arrange them in such a manner that the house can be always
ventilated without fear of the entrance of wet or burglars by leaving the house
with the windows slightly open, while a room can be ventilated without draught,
moreover weights are dispensed with which effects a saving in the cost of con-
struction, while no lines are employed, chains being utilized to replace them, and
the sashes are further arranged in such a manner as to be readily removable,
while a fastener of improved form is arranged at the bottom of the window instead
of at the meeting rails which securely fastens the sashes in either the opened or
closed positions.
In carrying my invention into practical effect, the sashes run in grooves in
the frame, so that beads are entirely dispensed with, while the ordinary cords and
weights are not employed, the outside sash being secured to the inside one upon
each side by a chain secured at each end to the two window sashes and passing
over suitably arranged pulleys at the top of the window frame, these chains
being secured to the sashes by small hooks or eyes engaging with a fixed pins on
the sashes.
The pulley style of the frame is solid upon one side while upon the other

sash can be taken out in a similar manner.

page_text: The fastening device for securely locking the window in either the closed
position or in the open position for ventilation, comprises a circular hook h
pivoted to a plate g suitably secured to the bottom of the inner sash and fur-
nished with a knob which acts as a balance weight keeping the fastener either
in the open or closed position as required, the stop being arranged to support.
the hook or fastener h¹ when in the unlocked position. The catch of the fastening
device comprises a plate furnished with two slots g g³ into
of which the catch of hook h enters passing out at the other. This
plate is let flush into the window sill and screwed down, a similar plate being
let into the ventilating hinged piece of which supports the window sashes when
opened for ventilating purposes, and by this means they may be firmly and
securely fastened in either the open or closed positions.

The sliding strips k (Fig. 4) which are firmly secured to the sashes and which
slide in the grooves g in the frame, preferably extend the full length of the sashes
and are covered with zinc or other suitable material, while a weather board w
of suitable form is secured at the top and outside the frame to prevent the entrance
of rain and also to break the force of the wind when the window is open.
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 improvements in or connected with windows comprising the arrangement
of sashes ab sliding on runners k in grooves g in the window frame, and con--
nected together by chains or other suitable flexible connections such as c passing
over suitably arranged pulleys such as p, the whole combined and arranged
substantially as herein described and shown, and for the purposes specified.
2. The combination with the arrangement of window sashes such as above

page_text: By the connection of the sashes with chains passing over suitably arranged
pulleys, it is obvious that when the inner sash is raised the outer one descends
or is opened. Now for purposes of ventilation, the inner sash is raised say four
or five inches and a suitable strip or piece of wood which is hung upon butt
hinges on the sill is raised and the sash closed down upon it where it is secured
in position by the fastening device hereinafter described. In this manner the
window is open at the top for the escape of the hot air while the space between
the inner and outer sashes serves for the admission of fresh air, while owing
to the two sashes being connected, the parts are all locked in this position by the .
aforesaid fastening device.
The fastening device comprises a circular hook pivoted to a plate at the bottom
of the sash and furnished with a knob or handle which acts as a balance weight
keeping the fastener either in the opened or closed position according as required,
while the catch of the fastener comprises a plate furnished with two slots into
one of which the end of the catch enters passing out at the other and this plate
is let flush into the window sill and screwed down, a similar plate being let
into the ventilating piece which supports the window sashes when opened for
ventilating purposes, and by this means they can be secured in either the open
or closed position.
The sliding slips which are secured to the sashes and which take into the
grooves in the frame, preferably extend the full length of the sashes, and are
covered with zine or other suitable material, while a suitable weather board secured
to the top and outside the frame is provided to prevent the entrance of rain and
also to break the force of the wind when the window is opened.
In order that my invention may be more fully understood, I will now proceed
to describe same with reference to the accompanying drawings in which:
Fig. 1 is a front elevation of a window frame and sashes constructed according
to this invention.
Figs. 2 and 3 show vertical sections through the window frame and sashes in
the position for ventilating and in the closed position respectively.
Fig. 4 is a cross section drawn at an enlarged scale as compared with the former
figs.
Fig. 5 is a front elevation of the catch or fastening used in connection with
the window, and
Fig. 6 is a view of a part of the pulley style showing the top of pockets.
According to this invention the sashes ab run in grooves g in the frame and
are connected together at each side perferably by chains at c which pass over
Euitable pulleys arranged at the top of the window frame, the chains being
secured to the sashes by means of small hooks h engaging with fixed pins p¹ on
the sashes.
The pulley style of the frame is solid upon one side, while upon the other it
is furnished with two pocket pieces extending more than half way up and which
are preferably secured in place by being dropped into a mortice in the sill and
having a flush bolt e at the top which engages with the solid portion d¹ of the
style.
By drawing back this bolt, the inner pocket piece 7 can be removed leaving
the sash free to swing into the room, when the chain can be unhooked and secured
to a pin (Fig. 6) upon the lower part of the outer sash, and upon releasing
the other side of the sash it is quite free for cleaning purposes or otherwise, and
the outer sash is left suspended. Upon the second pocket piece being removed,
the outer sash can be released in a similar manner.
For the purposes of ventilation, the inner sash 6 can be sufficiently raised and
a suitable strip of wood f, which is hung upon butt hinges on the sill, is raised
and turned over on to the sill and the sash closed down upon it as shown Fig. 2.
In this manner the window is open at the top for the escape of the heated air,
while the space between the inner and outer sashes b a serves for the admission
of fresh air.
