Improvements in Window Frames and Sashes.
JOHN LUMLEY Builders Foreman 17 Haywra Street Harrogate County of
York THOMAS LINSKILL Builder Mowbray House Harrogate do hereby declare
the nature of this invention to be as follows:-
Our improvements consist in a combined arrangement for making self balancing
and other sliding sashes reversible by turning the outside of the sashes inwards
for the convenience of cleaning and glazing from the inside.
The sashes are balanced by a wheel fixed in the center of each side of the frame
and upon this wheel is fixed small rollers which engage in notches made upon the
outside of the hanging stiles of the sashes or balanced by a chain connected to the
hanging stiles of the top and bottom sashes by passing over pulleys fixed in the head
of the window frame.
The head of the window frame is rebated to allow the bottom sash to be raised
higher than the top sash and the outside lining of the frame is reduced in width in
the lower half to allow the top sash when lowered to the bottom of the frame to
be reversed.
The sashes turn horizontaly and are pivoted to guide pieces or hanging stiles
which slide in grooves made in the frame the top sash is weathered and held in an
upright position when raised to the top by sliding behind that portion of the lining
which is not cut away.
In order to reverse this sash it is lowered to the bottom, and the bottom sash is
raised to the top and as before stated the head of the frame is rebated which
allows it to be raised to a height sufficient to allow the top sash to turn or reverse
under it. The bottom sash is hinged or pivoted to the hanging stiles and inversely
rebated above and below the hinge and will completely reverse to a vertical
position inside.

Improvements in Window Frames and Dasmes.
JOHN LUMLEY Builders Foreman 17 Haywra Street Harrogate County of
York and THOMAS LINSKILL Builder Mowbray House Harrogate 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 improvements consist of a combined arrangement, for making self balancing
and other sliding sashes reversible by turning the outside of the sashes inwards
for the convenience of cleaning and glazing from the inside.
The sashes are balanced by a wheel fixed in the centre of each side of the frame
upon the
and upon this wheel is fixed small rollers which engage in notches made
outside of the hanging stiles of the sashes or balanced by a chain connected to the
n

page_text: hanging stiles of the top and bottom sashes by passing over pullies fixed in the head
of the window frame.
The head of the window frame is rebated to allow the bottom sash to be raised
higher than the top sash and the outside lining of the frame is reduced in width in
the lower half, to allow the top sash when lowered to the bottom of the frame, to
be reversed.
The sashes turn horizontally and are pivoted to guide pieces or hanging stiles
which slide in grooves made in the frame.
The top sash is weathered and held in an upright position when raised to the
top, by sliding behind that portion of the lining which is not cut away.
In order to reverse this sash it is lowered to the bottom, and the bottom sash is
raised to the top, and as before stated the head of the frame is rebated, which
allows it to be raised to a height sufficient to allow the top sash to turn or reverse
under it.
The bottom sash is hinged or pivoted to the hanging stiles and inversely
rebated above and below the hinge, and will completely reverse to a vertical
position inside.
In the accompanying drawings, the letters of reference, refer to the same parts
throughout the different figures.
Fig. 1 is a section of the head of the window frame and also shows the head of
the top sash. (a.) the outside lining (b) the top parting lath (c) the sash head
(d) the staff bead (e) the head (m) the inside lining.
It will be seen by this section that the formation of the head of the window
frame will allow the bottom sash to be raised to a sufficient height to allow the top
sash when lowered to the bottom of the frame, to be reversed, or, the outside of
the sash turned inwards for the purpose of cleaning or glazing from the inside.
By this arrangement steps are not required, to clean or glaze the top sash, as
would be the case if the top sash could not be reversed when lowered to the bottom
of the frame and the bottom sash raised to a height to allow it to be turned
inwards.
Fig. 2. is a section of the balancing arrangement, one sash being made to
balance the other. On each side of the frame, about the centre, where the two
sashes meet, is fixed a wheel or pulley. Upon one side of this pulley is fixed,
three, four or five small rollers xxx which engage in teeth or notches s s s s s s
formed upon the outside of the hanging piece, to which the sash is pivoted.
The wheel or pulley (y) is fixed in a small metal frame (k) which is the same
size as the parting head (6) but in order that the wheel or pulley carrying the
small rollers, may be clearly shown, this frame is not shown to cross the wheel or
pulley but, it is shown to do so in section Fig. 3.
The wheel or pulley is let in or sunk into the frame, the small rollers & only
projecting, this is shown in Fig. 3.
By the use of the small rollers the friction is lessened upon the teeth ss.
They also decrease the friction of the sash upon the frame, thus, allowing the
sashes to move up or down freely.
The sashes inay be balanced by a chain passing over pullies in the head of the
frame and connected to the hanging pieces of the top and bottom sashes, or, they
may be hung in the ordinary way, by cords & weights.
In section Fig. 3-(k) is the metal frame in which the wheel or pulley carrying
the small rollers a revolves (y) the wheel or pulley (4) the centre upon which it
turns (b) the parting bead (pp) the sash frame.
Fig. 4. is a part elevation of one side of the frame and sash, showing the top
portion of the same (a a) the outside lining (oo) the sash stiles (n) the hanging
pieces or stiles.
Fig. 5. is a section of the lower part of the frame and
Fig. 6. a section of the top part of the frame.
In Fig. 4 the outside lining (a a) is shown to be reduced, below the meeting
rails of the sashes at the point (j).

page_text: The top sash is weathered and held in a position, that it cannot be reversed by
passing behind that portion of the lining (a) which is not reduced in width as on
line (A B) and section Fig. 6.
On the line (CD) and section Fig. 5 the lining (a) is reduced or cut away from
the point () to the bottom, this allows the bottom sash to be reversed also the top
sash when lowered.
Fig. 5. is a section of Fig. 4. on line (CD) (oo) the sash stiles (p) the frame
(nn) the hanging pieces (a) the outside lining and (m) the inside lining.
Fig. 6 is a section of Fig. 4 on the line (A B)-(o) the sash stile (b.) the
parting bead (a) the outside lining (n) the hanging stile (p) the sash frame (m) the
inside lining.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1st. The construction of the head of the window frame as described in the
Specification and shown by drawing Fig. 1.
2nd. In the construction of the balancing arrangement as described in the
Specification and shown in drawings Figs. 2 and 3.
3rd. The construction of the outside lining, by cutting away the bottom part
and having the top portion wide enough to cover the joint between the hanging
and sash stiles as described in the Specification and shown by the drawings
Figs. 4. 5 and 6.
