JAMES COOK, No. 2, Roseburn Street, Edinburgh, in the County of Mid-
Lothian, North Britain, Engineer, 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 relates to improved means for opening sash windows inwardly
in order to assist the cleaning, repairing and painting of same.
In the carrying
out of my invention I provide a temporary hinge at the one side of the lower sash
and an arrangement at the other side of the sash by means of which that side
of the sash can be released from the batten rod at the side of the window frame
and the other side of the sash withdrawn from its batten rod and swung upon
the temporary hinge provided for the purpose.
In lieu of the first referred to batten rod being permanently screwed to the
window frame, I attach it thereto by any simple locking bolts or keys and so
make it removable.
Then the cord carrying the weight is not permanently attached to the side
of the sash but is attached to a metal catch piece which can be readily connected
to and disconnected from another catch piece which is permanently fixed to the
side of the sash at the place where the end of the cord is usually fastened, the
arrangement being such that by pulling down the cord with the hand, the catch
piece is disengaged from the catch on the sash so that the sash can be entirely
drawn or turned in towards the inside of the room. The other end of the sash
is then drawn out from its batten rod and hung upon a hinge which may consist
of a metal bracket plate permanently attached to the window frame and which
has a hole through the projecting part of the bracket which hole is placed under
a pin provided upon another bracket permanently fixed to the window sash, so
that the whole sash can be opened inwards after the manner of a door; I may
employ a pair of such hinges one at the top of the sash and the other at the
lower part thereof.
The upper sash can be readily cleaned by simply drawing it down so that the
cleaner can extend his arm to the outside."
The upper sash may also be made to open inwards by the same means as above
described with reference to the lower sash.

I, JAMES COOK, of No. 2, Roseburn Street, Edinburgh, in the County of Mid-
Lothian, North Britain, Engineer, 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 relates to improved means for opening sash windows inwardly
in order to assist the cleaning, repairing and painting of same, and consists in
the employment of specially constructed temporary hinges which can be fitted
to existing sashes without altering same in any way.
But in order that my said invention may be more readily understood and
easily carried into effect I have hereunto appended an explanatory sheet of
drawings in which
Fig. 1 is a perspective view shewing a lower window sash fitted with my
improvements.
Fig. 2 is a perspective view shewing the means for retaining the batten rod
in position.
Fig. 3 is an elevation of a portion of the top sash shewing one of the hinges
upon which it is turned inwards and
Fig. 4 is a plan of both sashes.
Fig. 5 is a detailed view of the socketed bracket shewn in Fig. 1.
Referring to the said drawings I screw or otherwise attach to the batten rod
at one side of the window frame, two brackets A each of which is formed with
a socket B. The hinges, which as before mentioned are of special construction,
consist of a brass or other metal plate cast or otherwise formed of the shape shewn,
that is to say with a tubular swelling B' to receive the one leg of a double
swivelling pin C the other leg c thereof entering the socket B in the brackets A.
The said double swivelling pin enables the temporary hinging to be speedily
performed and does not in the least interfere with the raising and lowering of
the sash in the ordinary way when required, whilst the double action of the pin
allows the sash to be drawn out of the frame without bevelling the edge of the
sash and also allows the sash to be turned more nearly parallel with the wall of
the room, when the wall is in the same line with the window.
The socket B of the bracket is, as shewn more particularly in Fig. 5, slightly
tapered from the bottom upwards and is rounded off at its lower end, forming a
shield by which the leg of the swivelling pin if projecting, and the sash raised
with force, is gently turned aside and a sudden shock to the bracket avoided.
A shield B² is also employed for preventing a similar shock should the sash be
hurriedly lowered whilst the pin is projecting.
The batten rod is secured by means of two, or more, anchor headed catches G,
the tail ends of which pass through the batten rod and are provided or formed
with lugs or projections arranged to engage with the diamond openings l,
formed in the lock-plates H screwed to the window case, as shewn more particu-
larly in Fig. 2. The removable rope J is attached to a plate K having norns k
which, in order to retain the rope in position upon the sash, are slipped below the
keeper-plate L.
The upper sash may be cleaned by simply drawing it down so that the cleaner
can extend his arm to the outside; or it also may be hinged if found more con-
venient. In the latter case the hinge may be formed as shewn in Figs. 3 and 4.

page_text: Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. The general arrangement, construction and combination of parts constitut-
ing the means for opening sash windows inwardly, without any alteration to
existing sashes, substantially as hereinbefore described and shewn in the accom-
panying drawings.
2. The combination of the double swivelling pin C, having one leg retained
in a socket portion B secured to the sash, with the bracket A having the tapered
socket B and shield 1, all so arranged that the depending leg of the swivelling
pin C can be inserted in the socket B to form a temporary hinge, or the leg be
disengaged to allow the sashes to slide as usual, substantially as and for the
purpose hereinbefore described and shewn in the accompanying drawings.
3. The means for detachably connecting the weight cord to one side of the
sash, consisting of the plate K at the end of the cord, formed with the horns k
arranged to enter below and engage with the plate L secured to the sash, sub-
stantially as herein before described and shewn in the accompanying drawings.
4. The arrangement and construction of the hinges of the upper sash, sub-
stantially as herein before described and shewn in the accompanying drawings.
Dated this 13th day of March 1899.
