Improvements in Windows.
Mrs. MARY LAVINIA PUZEY, The Ferns, Lyonsdown Road, New Barnet, in
the County of Herts, do hereby declare the nature of this invention to be as
follows:-
This invention applies to windows with sliding sashes and is for the purpose of
constructing them in such manner as to allow of the opening into the room to
facilitate the cleaning of the outside of the glass.
The sashes are hung with lines either on one or both sides and are made to hinge
to open inwards as casements in the following manner.
A hollow runner is formed in the pulley style on one side of circular shape and
having an opening or slot throughout its entire length of about one fourth of its
circumference. The runner may be formed in the wood or of metal one for
each sash.
+
To each of the sashes a pair of hinges are fixed having a cylindrical cross bar at
the end to work in the runner referred to. The ordinary stop and parting. beads
are dispensed with and in the place of same cocked beads are formed projecting
beyond the face of the pulley styles into the edge of the style of bottom sash, the
sash sliding freely on the same.
Similar beads may be put to the top sash but terminating at the meeting
rail level.
To open the bottom sash the cock bead of the pulley style opposite the hauging
style is moved back out of the edge of the style of the sash which is then lifted
until the bottom rail clears the bead on the cill and then swing inwards. The
movable cock bead to the bottom sash is made as follows. A style or pocket piece
is formed in the pulley style and hinged to open back into the boxing of the frame
and the bead being fixed into the same is carried back with it.
On this pocket piece a guard formed of metal or other suitable material is fixed
which may be the entire height of the sash, which would then also form a further
protection for draught exclusion. The cock bead in pocket piece is formed in such
shape that on the sash being closed into the frame, it strikes the projecting portion
of the guard and brings forward and closes the pocket piece bringing with it the
bead into proper position.
As an alternative this pocket piece can be closed by an eccentric or a rachet
arrangement in conjunction with a spring or weight.
To open the top sash inwards for cleaning it is pulled down until its top rail
clears the beads when it will swing inwards providing the bottom sash is
opened.
If the sashes are hung on both sides the cord on the side opposite the hinges is
released from the sash by means of a lever with hook arm carrying the end of the
cord back out of the edge of the sash into the pulley style of the frame.
The length of the movable portion of the cock bead, with its pocket piece will be
about the length of the bottom sash.

page_text: I, MARY LAVINIA PUZEY, of The Ferns, Lyonsdown, New Barnet, in the
County of Hertford, Married Lady, 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 applies to windows with sliding sashes and is for the purpose of
constructing them in such manner as to allow of the opening into the room to
facilitate the cleaning of the outside of the glass.
The sashes are hung with lines either on one or both sides and are made to hinge
to open inwards as casements in the following manner.
The
A hollow runner is formed in the pulley style on one side and having an opening
or slot throughout its entire length. The runner may be formed in the wood or
of metal one for each sash. To each of the sashes a pair of hinges are fixed
baving a cross-bar or head at the end to work in the runner referred to.
ordinary stop and parting beads are dispensed with and in the place of same
cocked beads are formed projecting beyond the faces of the pulley styles into the
edge of the style of bottom sash, the sash sliding freely on the same.
Similar beads may be put to the top sash but terminating at the meeting
rail level.
To open the bottom sash the cock bead of the pulley style opposite the hanging.
style is moved back out of the edge of the style of the sash which is then lifted
until the bottom rail clears the bead on the sill and then swung inwards. The
.movable cock bead to the bottom sash is made as follows:-A style or hanging
piece is formed in the pulley style and hinged to open back into the boxing of the
frame and the bead being fixed into the same is carried back with it.
On the hanging piece a guard formed of metal or other suitable material is
fixed which may be the entire height of the sash, which would then also form a
further protection for draught exclusion. The cock bead on the hinged piece is
formed in such shape that on the sash being closed into the frame, it strikes the
projecting portion of the guard and brings forward and closes the hanging piece
bringing with it the bead into proper position.
To open the top sash inwards for cleaning it is pulled down until its top rail
clears the parting bead when it will swing inwards providing the bottom sash is
opened.
If the sashes are hung on both sides the cord on the side opposite the hinges is
released from the sash and its end secured by any suitable means.
The length of the inovable portion of the cock bead with its hanging piece will
be a little more than the height of the bottom sash.
But in order that my invention may be fully understood I will now proceed to
describe same by the aid of the accompanying drawings, in which
Fig. 1 is an elevation (partly in section) of the inside of a window constructed
according to my invention.
Fig. 2 a horizontal section of same with the sashes in their closed position.
Fig. 3 a horizontal section with the sashes opened inwards.
Fig. 4 a horizontal section of one of the sashes drawn to an enlarged scale and
showing the hinge on which such sash turns.
Fig. 5 a similar view showing a slightly modified form of such hinge.
Fig. 6 a front elevation of the cocked bead formed on the hinged hanging piece
and which enters a groove in the bottom sash.
Fig. 7 a horizontal section of such cocked bead and hanging piece in the position
when the window is closed, and

page_text: Fig. 8 a corresponding view with the parts in the position when the window is
opened inwards.
A, A, are respectively the bottom and top sashes, each of which is on one side
mounted on hinges B, B₁, formed with a cross-bar or head b, b', sliding in a
runner C, C, let into the pulley style on one side of the window frame. In
Figs. 1, 2, 3 and 4 the runners in which the cross-bar or head b, 1, of. the
hinges B, B¹, work are of rectangular cross section, while in the modification
shown in Fig. 5 such runners are of circular section.
The cocked bead D for entering the groove in the bottom sash when the window
is closed, is mounted or formed upon a hinged hanging piece E inserted in the
pulley style on the opposite side to that at which the window sashes are hinged.
The hinged hanging piece E is fitted with a projection or guard F on its outer
side. Such hinged piece when the window is closed is held in position by a
movable pin G or other suitable means.
The operation is as follows:-
When it is desired to open the sashes inwards for the purpose of cleaning the
outside of the window, the pin G is removed from the hanging picce E, and the
bottom sash is raised until the bottom rail clears the bead on the sill. The bottom
sash A is then turned on its hinges B to the position shown in Fig. 3, the turning
of the sash causing the cocked bead D and hanging piece E to turn on its hinge
out of the way of such lower sash.
The top sash A' is then lowered until its top rail clears the parting bead H,
which only extends down to about half way of the pulley style. The upper
sash A¹ can then be turned inwards on its hinges B' to the position shown in Fig. 3,
thus enabling the outside of this sash to be also cleaned.
To close the window the operation is reversed, the upper sash being first turned
outwards on its hinges and then raised; the lower sash is then turned on its
hinges, and in its movement comes in contact with the projection or guard F on
the hinged hanging piece E, which causes it to turn so that the cocked bead D
again enters the groove in the lower sash when the lower sash can be pushed down
and the window so closed. The pin G is then again inserted so as to fix the
hinged hanging piece Ę in position.
Fig. 9 is a front elevation, partly in section, of a window sash hung in the
ordinary way on both sides (instead of on one side only as in the arrangement
previously described) and having my invention applied thereto.
Fig. 10 is a horizontal section of such modification, and
Figs. 11 and 12 are respectively a vertical and horizontal section on an enlarged
scale of a suitable arrangement for securing the ends of the cords on one side to the
sashes, so as to enable such cords to be detached when it is required to turn the
sashes on their hinges.
The end of the pulley cord I on the side opposite to that at which the window
sashes are hinged, is secured to a pin K (which is preferably split as shown),
which is inserted in a recess in the edge of the sash, such recess slanting upwards
so that the pull of the weight on the cord will tend to keep the pin in position.
When required to turn the sash on its hinges the pin K is removed from the
recess in the sash and inserted in a corresponding recess L formed in the pulley
style, thus releasing the sash so that it can be turned on its hinges, while retaining
the cord I until the sash is again closed, when the pin K will be again inserted in
the sash.
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 combination with the sashes of sliding windows which are hinged on one
side and have a part sliding in runners inserted in the pulley style, of a cocked
bead formed upon or secured to a hinged piece mounted on the other style of the
window frame, such cocked bead entering a groove in the lower sash when same is

page_text: closed, and of a projection or guard carried by such hinged piece for the purpose
of returning the cocked bead into position by the action of closing such lower
sash.
2. The combination with the arrangement set forth in the preceding claim of
means for detachably securing the pulley cords on one side of the window sashes,
substantially as described.
