Improvements in Window Frames.
DAVID CALDOW SIMPSON 31 Woodford Road Forest Gate, in the County of
Essex, Builder, do hereby declare the nature of this invention to be as follows:-
The "revolving window frame" is a frame of an ordinary kind for sashes and
weights, made to revolve perpendicularly within an outer frame. In the centre of
the bottom and top of the outer frame, are sliding sockets of metal in which are
drilled holes corresponding to the size of two pivots fixed in the centre of the top
and bottom of the inner frame. The sliding sockets are respectively turnel up on
the inner side of the outer frame at the top, and down on the inner side of the outer
frame at the bottom. The turned up and down parts of each socket are drilled with
boles for screws or nails. The mouldings on the inside of the window frame are
fixed to, or unfixed from the outer, by a screw fastener which passes through a
horizontal slot in the mouldings into the inside surface of the outer frame, so that
when the knob of the fastener is screwed up tight it presses the moulding against
the inside surface of the outer frame and overlaps the junction between the outer
and inner frame so as to secure the inner window frame in its place and prevent
any draught from entering the room. When the fastener is unscrewed the
moulding can be slipped back by means of the slot and then, the whole of the
window frame that carries the sashes can be turned on the pivots inside out.
The top moulding on the inside is fixed in similar manner to the side mouldings,
only that the slots are perpendicular. The small space between the sills of the
inner and outer frames is covered on the inside by a bevelled slip of wood or metal
placed in or out of a ploughed groove made in the nozing of the window frame.
The outer frame is made flush with the inner frame on the inside, but is kept back
from the outer surface of the inner frame about two inches thus allowing the stone
or brickwork to set back from the outside surface of the inner frame. The back
linings of the inner frame are not continuous from top to bottom but are shortened
both top and bottom sufficiently to allow of the sash weights being put in without
the aid of pockets. Near the ends of the sill of the outer frame are two small
rolers let in nearly flush with the surface of the sill and working at right angles
with the same so as to cause the window frame to revolve with ease. Beneath
the sill of the inner frame near the outer edge is a ploughed groove to form
a drip.

Improvements in Window Frames.
DAVID CALDOW SIMPSON, Builder 31 Woodford Road, Forest Gate Essex
I 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 certain improvements in window frames, and has for its
object the adjustment of the outer frame in such a manner that it may be turned

page_text: or reversed upon a central pivot for purposes of repairing or cleaning. The
ordinary balanced sash is employed, and normally the top and bottom sashes may
be raised and lowered against the sash weights or equivalent counter balances as in
the case of ordinary window fittings. The whole enclosing frame is arranged to
revolve and reverse its facia, and to be locked when in its normal position, and the
free openings necessary for the movement rendered weatherproof.
In order that my invention may be the better understood, I have appended the
accompanying sheet of drawings, in which
Figure 1 is an elevation of the device, partly in section and
Figure 2 a transverse section upon the line X Y Figure 1.
Figure 3 is a perspective view of the upper sliding socket of the pivotted sash.
Similar letters of reference indicate corresponding parts throughout the several
views.
In carrying my invention into effect, I employ an ordinary window frame I,
carrying upper and lower sashes V V which may be opened, closed and fastened
in the manner usually employed in fixed sashes and fittings. At the centre of the
outer frame E, and upon the lower member thereof is fitted a socket hole C in
which a pivot B placed upon the under part of the sill of the ordinary window
frame 1, a corresponding pivot A being arranged to engage with a sliding socket D
upon the top of said frame. Upon these two pivots the enclosing frame I, carrying
the sashes VV' may be revolved and their respective surfaces reversed. The
eliding socket D upon the upper part of the frame I is bent rectangularly and
screwed or otherwise attached to the frame, so that it may readily be removed
thus releasing the frame which may be lifted free of the lower socket C, away
from the outer frame E. I prefer to construct the surrounding mouldings in such
a manner that they are removeable and interlock by a system of rebating herein-
after to be described. Said mouldings are fixed to, or have formed thereon and
integral therewith, strips of wood G which fit between the ordinary window
frame I and the outer frame E. Said slips of wood extend from the inner surface
of the frame to within a short distance of the outer surface thereof. The top
mouldings are fixed to the outer frame E by means of thumb screws H, which
when slightly unscrewed allow of the moulding aforesaid being lifted by means of
perpendicular slots S so as to be clear from the ordinary window frame I. The
mitres at the ends of the mouldings are rebated so that the top moulding F
overlaps the side mouldings F, thus keeping them in position when the aforesaid
top moulding F is screwed in place by the nut H, constituting the locking device
hereinbefore referred to. When said top moulding F is released, and lifted out of
its place, the side mouldings F and the slips G to which they are fixed may be
lifted out, thus freeing the window frame I which may then be turned upon the
pivots C and D. Referring to the sectional plan Figure 2, an ordinary nozing J is
fixed to the bottom of the outer frame E' and at the back of said nozing is a
groove K in which is fitted a bevelled moulding L Figure 1 which overlaps the
cavity between the sill of the ordinary window frame I and the outer frame E³, and
forms the lower member of the moulded frame F F and L, and which may be
lifted out of the groove K when the mouldings F are removed. When all the
mouldings are in position the opening or parting between the window frame I and
the outer frame E' is overlapped and rendered weather proof. The outside
lining M of the window frame is made slightly wider than the inner lining N as
shown by Figure 2, so that it overlaps the slips G herein before described. The
sides and top of the outer frame E are made to be of the same width as that of
the inuer frame 1, but the sill of said outer frame E is less in width than that
of the window frame 1, in order to allow any stone sill or brickwork from the
outside setting in beneath said frame 1 1. Upon the two outer edges of the outer
frame E are fixed two slips of wood O, so that when the mouldings F carrying the
strips G are in place they shut against said slips O. At the ends of the sill of
the outer frame E are pivotted two rollers P for the purpose of reducing friction
and enabling the window frame 1 1 to be freely revolved upon the pivots C D.

page_text: 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 ;
A frame 11 carrying sashes and weights made to revolve within an outer
frame E E' substantially as herein before described and shown by the accompanying
sheet of drawings.
