THOMAS MARCUS HOUGHTON Hersham in the County of Surrey. Quantity
Surveyor do hereby declare the nature of this invention to be as follows:
This invention applies to windows having sashes hung with lines and weights that
is to say sliding sashes and has for its object the opening of the sashes in such
manner that the outside face of the glass may be cleaned or the woodwork painted
from the inside of the room.
The window is constructed as follows.
I omit the usual parting and stop heads excepting the stop head to the cill of the
frame. The pulley styles are rebated for the bottom sash and cock beads or fillets
are fixed to or inserted in the pulley styles with corresponding grooves in the styles
of both the top and the bottom sashes so that the said beads or fillets may work in
the same easily when the sashes are lifted up or pulled down all four of the beads
terminate at or about the height of the meeting rails when the sashes are closed.
To one of the pulley styles I fix metal pins or pintles reaching from the cill to
the head of the frame one for each sash, straps or hinges of metal of suitable shape
are fixed to the sashes and sliding on these pintles in such manner that the sashes
may in addition to .sliding up and down be opened into the room with a similar
motion to a door on its hinges or a casement light the sashes being prevented from
sliding down the pintle by the weights which are attached to same on that side of
the frame by cords or chains in the ordinary manner. To open the top sash
inwards for cleaning as described (when the top sash is less in height than the
bottom sash) it is pulled down-until its top.rail clears the. cock beads. When the
sashes are of about equal height the cock head is treated in a similar manner as here-
after described to the bottom sashes. The bottom sash cannot be opened inwards
until the cock bead of the pulley style is removed out of the groove in the sash style
when it can be opened in a similar manner as the top sash that is to say inwards;
the movement of this cock bead is accomplished thus It is made to project
beyond the face of the rebate in the pulley style about " and into a groove in the
pulley style about the groove being made about " deep the bead is then fixed at
intervals to a batten or runner which is made to slide up and down at the back of
the pulley style that is to say in the boxing of the frame. Small blocks are fixed
to this runner of the thickness of the pulley style less the distance which the cock
bead passes into the groove. and slots are cut in the base of the groove for the
blocks to work in and through. To the ends and in the centre of the runner if
found necessary suitable guides are fixed working in corresponding guides on the
back of the pulley style so that on lifting up the runner the guides carry it back and
with it the attached bead into the groove in the pulley style and out of the groove
in the style of the sash.
The bead may be moved back by pressure on its face edge on raising the sash
for that purpose or the runner may be raised by a screw knob attached to same and
passing through a slot in the inside lining or other similar contrivance. When the
sashes are of equal height the cock bead of the top sash would be fixed to the same
or a similar runner.
Preferably I only use one weight to each sash viz. in the boxing on that side of
the frame to which the pintles are attached but as an alternative
may make each
weight in two sections one section balancing one side of the sash and the corre-
sponding section balancing the opposite side of the sash in manner following.

page_text: The two sections of each weight are made to slide slightly against each other and
are held in that position by suitably shaped clips or bands and that section of the
weight which balances that side of the sash nearest the pintle has a stop which
prevents the other section from falling more than about a quarter of an inch when
its cord is released from the sash this cord is carried up and across the head of the
frame either under or over the same and continued down vertically on the face of
the pulley style to the style of the sash and connected. The cord is made to run
in suitable pulley wheels across the head.
The cords are attached to the sashes and released automatically in the following
manner.
"The cords or chains have a metal hook or arm fixed to the same the back sliding
against the pulley style and with a wedge shape projection from the face, this
projecting part engages with a plate or socket fixed to the sash thus on pulling the
sash forward into the room the socket on the sash slides off the wedge shape
projection on the metal hook or arm of the cord and the weight in opposite side
boxing of the frame falls on to the stop of the other section of the weight before
mentioned. On pushing back the sash into the frame the reverse action takes place
the weight being lifted off the stop of the corresponding section and consequently
takes its share of the weight of the sash on opposite side. This applies to both of
the sashes.
As an alternative to a circular pintle as previously described herein with the
hinge of the sash working & sliding on the face of the same I may use a hollow
tube or channel of suitable shape fixed to the pulley style and the ends of the
hinges fixed to the sashes being of corresponding shape will elide up and down in
the same and open at any point in the height of the frame.

I, THOMAS MARCUS HOUGHTON of Hersham in the County of Surrey, 3
Quantity Surveyor, do hereby declare the nature of the said 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 applies to windows having sashes hung with lines and weights,
that is to say sliding sashes, and has for its object the opening of the sashes in such 3
a manner that the outside face of the glass may be cleaned or the woodwork painted
from the inside of the room.
The window is constructed as shown in the accompanying drawings in which
Figure 1. is an elevation of the window when closed, part being broken away.
Figure 2. similar view, one sash being shown as brought into the room or other 4
place lighted by the window.
Figure 3. sectional plan of Figure 2, on line xx.
I omit the usual parting and stop heads excepting the stop head to the cill of the
frame. The pulley styles are rebated for the bottom sash, and cock beads or
fillets a. are fixed to or inserted in the pulley styles with corresponding grooves b, 4
in the styles of both the top and bottom sashes so that the said beads or fillets may
work in the same easily when the sashes are lifted up or pulled down, all four of
the beads terminate at or about the height of the meeting rails when the sashes are
closed.
To one of the pulley styles I fix metal pins or pintles c, c, reaching from the cill 5
to the head of the frame one for each sash, straps or hinges d. d. of metal of
suitable shape are fixed to the sashes and slide on these pintles in such a manner.

top sash inwards for cleaning as described (when the top sash is less in height than
the bottom sash) it is pulled down until its top rail clears the cock beads. When the
sashes are of about equal height the cock bead is treated in a similar manner as
hereafter described with reference to the bottom sashes. The bottom sash cannot
be opened inwards until the cock bead of the pulley style is removed out of the
groove in the sash style, when it can be opened in a similar manner as the top sash
that is to say inwards; the movements of this cock bead is accomplished thus.
It is made to project beyond the face of the rebate in the pulley style about **
and into a groove in the pulley style about " the groove being made about " deep
the bead is then fixed at intervals to a batten or runner e. e. which is made to slide
up and down at the back of the pulley style that is to say in the boxing of the
frame. Small blocks are fixed to this runner of the thickness of the pulley style
less the distance which the cock bead passes into the groove and slots are cut in the
base of the groove for the blocks to work in and through. To the ends and in the
centre of the runner if found necessary suitable guides are fixed working in
corresponding guides on the back of the pulley style so that on lifting up the
grooves in
runner the guides carry it back, and with it the attached bead, into the
the pulley style and out of the groove in the style of the sash.
The bead may be moved back by pressure on its face edge on raising the sash
for that purpose, or the runner may be raised by a screw knob, f, attached to same
and passing through a slot in the inside lining or other similar contrivance. When
the sashes are of equal height the cock bead of the top sash would be fixed to the
same or a similar runner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. A window constructed so as to open inwards as stated having the pintles or
bars c, c, and hinges d, d, in combination with the bead or beads a moving within
the pulley style as described and shown in the drawings.
2. The means for actuating the bead as described and shown.
