Improvements in Sash Windows.
I, HERBERT CHARLES NORFOLK, of 66, Brockley Road, Brockley, Kent,
Gentleman, do hereby declare the nature of this invention to be as follows:-
My invention has for its object to enable the outer surfaces of sash windows to
be cleaned from the interior of the apartment, and it consists in providing means
whereby both the upper and lower sashes when in the completely lowered position
may be removed from the grooves of the window frame and swung into the apart-
ment until they are at about right angles to their normal position or at least
sufficiently to bring the outer surfaces of the windows within easy reach.
According to my invention, I construct the window frame as follows:-At the
one side of the lower sash the groove in which the sash slides is (for a height at
least equal to that of the sash) made separate from the rest of the window frame
and is hinged thereto, so that it may be swung in towards the apartment, and
means are provided whereby the sash may be temporarily connected to such hinged
portion so as to swing therewith as one upon its hinges, the beading of the grooving
at the opposite side to permit of this swinging motion of the sash, and the sash
line at the last mentioned side of the sash, being both detachable so as not to
interfere with the swinging motion of the sash which is supported during its
swinging motion by its connection with the hinged portion of the frame and by the
sash line and counterweight at the hinged side of the sash. Similarly as regards
the upper sash, the lower part of that one of the grooves in which it slides (which
is situated at the opposite side of the window to the hinged groove portion of the
lower sash) is likewise made separate from the window frame and hinged, and
similar means of connecting the sash to the hinged portion are provided so that
the sash and the part to which it is hinged may be swung together on the hinges
as one, and the sash line at the side opposite the hinge is made detachable, as
before so that this sash also may be swung in towards the apartment.

I, HERBERT CHARLES NORFOLK, of 66, Brockley Road, Brockley, Kent,
Gentleman, 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 has for its object to enable the outer surfaces of sash windows to
be turned so far towards the interior of the apartment that they may be cleaned
without the risk of accident incidental to outside cleaning in the usual way, and it
consists in providing means whereby both the upper and the lower sashes may
when in the completely lowered position be removed from the grooves of the
window frame and swung towards the interior of the apartment until both of the
DO71

page_text: sashes project inwards in such positions that the outer surfaces of the windows
are within easy reach and this without necessitating the removal or interfering
with the arrangement of the blinds, curtains, or hangings.
An incidental advantage of the invention is the facility afforded for the
renewal of sash lines without damage to the painted work of the window frame.
Reference is to be had to the accompanying drawings, forming part of this
Specification, in which
Figure 1 is an inside face view of the window.
Figure 2 is a similar view with the lower sash only swung inwards.
Figure 3 is a similar view, both sashes being swung inwards.
Figure 4 is a vertical section on line 4-4, Figure 2, and
Figure 5 is a horizontal section on line 5-5, Figure 3.
According to my invention I construct the window frame A as follows:-At
the one side of the lower sash B the groove bin which the sash slides is (for a
height at least equal to that of the sash) formed in a piece C separate from the
rest of the window frame A. This piece C which comprises the bead c, the
parting strip c', and the cover of the weight box, is hinged at D to the window
frame A so that it may be turned back towards the interior of the apartment, as
shewn, thereby disclosing the box in which the sash weight is hung. Means are
provided whereby the sash B may be temporarily connected to such hinged
portion C so that the sash will swing therewith as a door on its hinges. Such
means may consist of a cross pin e inserted through holes in the bead c and
parting strip c', and through a hole made in a metal shoe piece screwed to the
stile of the sash, the last mentioned hole corresponding to the holes in the bead
and strip when the sash is slightly raised so as to pass clear of the bottom bead.
At the opposite side of the, window there is a loose piece F which may be
wholly removable or be hinged at its upper or lower end, this piece comprising the
bead and the cover of the weight box so that when the piece F is removed the
sash B may be swung back, as in Figures 2 and 3, and the weight box is opened
for access to the weight in case of need. The part F may be fixed in position by
pins, as shewn, and when unfastened or removed or thrown back it allows of this
edge of the sash B being swung inwards sufficiently to admit of the sash line G
being detached so that the sash B together with the part C may then be swung
fully inwards upon the hinges D, as shewn in Figures 2 and 3. To facilitate the
detachment of the sash line G its end is looped or otherwise adapted to be
connected to a hook or stud fixed to the edge of the sash stile and to prevent the
weight dropping to the bottom of its box when the sash line is disconnected from
the sash the line is temporarily attached to a hook on the window frame, as in
Figures 2, 3, and 4.
The upper sash H when in its lowered position, as shewn in Figures 2 and 4,
is made to swing inwards on its hinges in a similar manner, that is to say the lower
part of the outer groove of the window frame (at the same side of the window as
the loose piece F) is made of a removable piece I hinged as at J to the window
frame and means (such as the pin k) are provided for temporarily connecting the
sash H thereto so that the sash will be supported by and swing with the piece
on its hinges J until the sash is brought to the position shewa in Figure 3, this
inward swinging motion of the upper sash being only permitted after the lower
sash has been swung inwards so that it and the parting strip c', have been moved
out of the way.
The sash line L is of course detached from the upper sash and temporarily
made fast as described in reference to the lower sash.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The herein described means of enabling window sashes to be swung inwards
towards the apartment for cleaning purposes, consisting of hinged parts of the

page_text: window frame forming portions of the sash grooves at opposite sides of the window,
means for connecting the sashes thereto so that they may turn therewith, and
meaus for freeing the opposite edges of the sashes from their grooves, all
substantially as herein specified.
