Improvements in and relating to Window Frames and Sashes
and the like.
We, HENRY JOHNSTONE, of 7 Sheppards Terrace, Decorator, and ALFRED.
TREMLETT JENNINGS of 9 Sheppards Terrace, Boiler Maker, both of Sholing in
the County of Hants do hereby declare the nature of this invention to be as,
follows:-
Our invention relates to window frames, and sashes and the like, and comprises
various improvements hereinafter described.
The main object of our said invention is to provide window frames and sashes so
constructed and fitted that the sashes can be very readily removed from the
window frames-more especially for the purpose of cleaning the glass panes-and
afterwards as readily replaced..
In making window frames and sashes according to one form or modification of
our invention the frame and sashes will be put together in somewhat similar
manner as now ordinarily adopted, but, with the following modifications; one of
the inner side, or vertical beads of window frame for the whole or part of its
length, is hinged at the bottom corner and arranged to fold down on to the inner
bottom bead.
The front of weight pocket, or part of same on one side of the window frame is
made in one with the parting bead, or a part of same, and. it can be removed at
will from the window frame, thus allowing of the outer sash being brought out of
the window frame at will, after the inner sash has been removed.
The above described portable piece is preferably fitted in a recess formed in
the front of weight pocket, and held in place by a mitre joint at the top, and a
flush sliding bolt at bottom end, or by other suitable means.
The hinged piece forming one of the inner side beads of window frame, or part
of same, as above described, is also held in place by a flush sliding bolt or other.
suitable fastening fitted at the top end.

Taking it that the sashes are fitted in place in the window frame and it is desired.
to bring one or both of the former out of same, the inner sash is raised to a con-
venient height and attached to the underside top part of window frame by means,
of a short piece of chain, or its equivalent, the chain is fitted with a hook at each
end, one preferably being a swivel hook, and flush socket plates are fitted in the :
top rail of both sashes and at the underside of top part of window frame, and
upon passing the said hooks respectively into the socket plate of the window,
frame, and of a sash, the connection of the latter to the former, by means of the
chain, is established, the object in making this connection is hereinafter described.
The sash cords and attached weights are then overhauled so as: to leave the i
cords in a bight or loop, and the latter. are prevented from being drawn back into
the pockets-by the weights-by passing wedges (preferably made of vulcanized
rubber) between the pulleys and cords, the weight of sash is thus entirely supported
by the aforesaid, chain. The hinged. inner bead is then folded down on to the
bottom front bead and there secured temporarily by a sliding bolt, or other
suitable fastening fitted at the free end of the hinged bead.
The inner sash frame may then be drawn forward out of the window frame and
the ends of sash cords-disconnected from the sash frame.
In arranging the connection of the sash cords to the sash we prefer to adopt
the following method, upon the ends of the cords opposite the weights we fit and
secure a metal ferrule and the ends, so fitted, are passed into specially designe}

page_text: socket plates fitted flush in the vertical sides of the sash frame at or near the top
part of same, a recess being cut in the sash to take the plates and ends of cords,
this arrangement will permit of the latter being very readily attached to, and
detached from, the sash frames.
The front sash frame, after the sash cords are disconnected from same, remains
suspended by the chain and it may be either unhooked and lifted down into the
room or, swivelled upon the chain in place, and the glass panes cleaned, and then
brought into the room, to permit of the outer sash being manipulated in similar
manner as the inner one, as hereinbefore described, previous to which it is obvious
the portable piece forming the parting bead must be removed: The reverse of
the above described operations must be effected when it is desired to replace, the
sash frames.
Many modifications may be made in the details of our invention without
departing from the distinctive character of same, for instance, the hinged side, or
vertical bead may be made in two lengths instead of one, as hereinbefore described,
and hinged at the top and bottom corners of window frame respectively the top
length being arranged to hinge up to the under side of the top horizontal bead
and the bottom length to hinge down on the top of the bottom horizontal bead,
the parts being temporarily secured in these positions when it is desired to remove
the window sashes.
This arrangement will be found necessary when the height of window frame is
considerably more than the breadth of same.

Improvements in and relating to Window Frames and Sashes
and the like.
We, HENRY JOHNSTONE, of 7 Sheppards Terrace, Decorator, and ALFRED
TREMLETT JENNINGS of 9 Sheppards Terrace, Boiler Maker both of Sholing, in
the County of Hants, 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 :-
Our invention relates to window frames, and sashes, and the like, and comprises
various improvements hereinafter described.
- The main object of our said invention is to provide window frames and sashes so
constructed and fitted that the sashes can be very readily removed from the window
frames more especially for the purpose of cleaning the glass panes-and afterwards
as readily replaced.
The accompanying drawings shew what we consider to be the best means of
carrying out our said invention, in which,

fitted according to one form or modification of our invention, and shewing the
bottom sash partly open.

Figs. 12, 13 and 14 shew enlarged views in elevation, plan, and side view
respectively of a detail hereinafter described.
Figs. 15, 16, 17, 18 and 19 views shewing a modification in detail hereinafter
described.
Like letters indicate corresponding parts throughout the drawings.
In making window frames and sashes according to one form or modification of
our invention, one of the vertical beads A, or part of same of the window frame is
hinged at the bottom corner and arranged to fold down when desired on to the top
of the bottom bead A', the length of the hinged piece is somewhat greater than
the depth of sash frames, thus when the said piece is folded down the sash frame B,
can be brought out of the window frame.
Further the parting bead C, or part of same is made portable and of a form in
cross section as shewn (see Figs. 2, 3, 4, 17, and 19) and a recess is formed in the
front D, of weight pocket to take the portable piece C, the length of same is
greater than the vertical height of sash frames thus when the inner sash is removed
and also the portable piece C, the outer sash can be brought out of the window
frame into the room.
The hinged piece A, is held in the vertical position when the sashes are in place
in the frame by means of a sliding bolt 6', and the same bolt serves to keep the.
hinged piece in position when it is folded down on the top of the horizontal bottom
bead A', as it (the bolt) is then slid forward into the vertical bead A³.
The portable piece C, is held in place in the front of weight pocket by means of
a sliding bolt c¹, or other suitable fastening which when withdrawn will allow of the
removal of the said piece from the window frame.
Taking it that the window sashes are in place in the window frame and it is
desired to bring the inner sash B, out of the window frame into the room the former
is raised to a convenient height as shewn on the drawings and attached by means
of a chain E, or its equivalent, to the underside top part of window frame the said
chain is fitted with a hook at each end one preferably being a swivel hook, and a
flush plate F, with a recess under same is fitted in the top rail of both sashes and
a similar fitting F1, at the underside of top part of window frame, and upon passing
the said hooks into the plates F, and F1, respectively the connection of the sash to
the window frame by means of the chain is effected.
The sash cords d', d', are then overhauled so as to leave them in a bight or
loop but the cords are prevented from being drawn back into the pockets, by the
weights, by passing wedges G, G, (preferably made of vulcanized india-rubber)
between the pulleys and cords (see Fig. 7.) the weight of sash is then entirely
supported by the chain E. The hinged piece A, of inner bead is then folded
down on to the bottom front bead A', and there secured temporarily by the sliding
bolt b¹.
The sash frame may then be brought forward out of the window frame, and the
ends of sash cords disconnected from the sash frame..
For the purpose of affording a ready and simple means of connecting the
sash cords to, and disconnecting them from the sash frames we adopt the following
arrangement.
Upon the end of the cords opposite to the weights we fit and secure a metal
ferrule H, and when connecting the cords to the sash we pass the ends so fitted into
the socket plates J, at the opening J', and the cords are thus held in the socket
plates until it is desired to release them.
The sash after the cords are disconnected from. same remains suspended by the
chain E, and it (the sash) may be, either unhooked and lifted down into the room
or swiveled upon the chain in place and the glass panes cleaned and the sash then
brought into the room to permit of the outer sash being manipulated in similar
manner as the inner one, as herein before described, previous to which it is obvious
the portable piece C, must be removed. The above described operation will be
reversed when it is desired to replace the sash frames.

page_text: Figs. 12, 13, and 14 shew enlarged views-in elevation, plan, and side view
respectively of the socket plate J.
Many modifications may be made in the details of our invention without departing
from the distinctive character of same. For instance, the hinged piece A, may be
made in two, three or more lengths instead of one and hinged at the top and bottom
corners of window frame, respectively, the top length or lengths being arranged to
hinge up to the underside of the top horizontal bead A³, and the bottom length or
lengths to hinge down on to the top of the horizontal bead A', the parts being
temporarily secured in these positions when it is desired to remove the window
sashes; this arrangement will be found necessary when the length of window
frame is considerably more than the breadth of same.
For long narrow windows we make and fit the bead A, in manner as shewn
by Figs. 15, 16, 17, 18, and 19 in which Fig. 15, is an inside elevation. Figs. 16
and 18 enlarged sectional elevations of parts of Fig. 15, and Figs. 17 and 19,
sectional plans of same taken on the line m, m, and n, n, respectively, in this
arrangement the bead A, made in three lengths, f, f' and f³, hinged at r,
.and P, and q; j is a hooked plate secured to the piece, which-when the pieces f*
and 3, are placed in the vertical position-engages with a plate j¹, secured to the
front of weight pocket. k, is a hinged angle plate secured to the front of weight
pocket.
When it is desired to remove the window sash the piece f¹, is hinged
upwards and the piece f³, folded down on to the piece f³, and together they are
folded down on to the bottom bead A', and temporarily secured in that position by
suitable means the front part of the hinged plate k, is then folded down and the
inner sash can then be removed from the window frame.
In replacing the bead A, in the vertical position the pieces f³, f², are folded
upwards, the hooked plate j, then engages with the plate j¹, securing the pieces f²,
and 3, in position, the piece f', is folded down and a sliding bolt 1,-provided in
the lower part of the piece f¹-is passed through the plate k, into the adjacent
end of the piece f, the whole length of bead A, is thus secured in the vertical
position, and consequently the window sash in place in the window frame.
The arrangement of the parting bead C, in the case of a high narrow window
frame as last described will be similar as that hereinbefore described for other
windows.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is:
1st. The improvements in, and relating to window frames and sashes comprised
in the parts constructed, arranged, and combined, substantially as described
with reference to the accompanying drawings, and operating as and for the purpose
specified.
2nd. The herein described devices for, and method of attaching the sash cords to
the window sash for the purpose specified.
3rd. In a window sash frame the new or improved methods of hinging and fitting
one of the vertical beads A, as and for the purpose specified.
4th. For a window sash frame the portable parting bead: C, so constructed and
fitted that it may be readily removed from, and re-inserted in, the window frame as,
and for the purpose specified.
