PROVISIONAL SPECIFICATION.
A Revolving Window.
I, ROBERT FLINT, of The Lorne Hotel, Rhyl, North Wales, Hotel Proprietor,
do hereby declare the nature of this invention to be as follows:-
My invention relates to a revolving window and the objects of my invention
are to enable both sides of the window panes to be cleaned from the inside of a
room, to check draughts and vibration during stormy weather, to enable the
window sash to be readily removed from its frame and to dispense with the cords
and weights usually employed to balance the sash.
According to my invention pivot the window sash on pins on opposite sides
of the sash and these pins fit into slots or bearings in or on the frame in such
manner that the sash can be readily turned completely round on its pivots and
when open, the pivots can be released from their bearings and the sash lifted
out.
Any suitable means may be employed to lock the sash partly open or in any
other required position.
I hinge wooden or other strips to the frame and these strips when closed over
the sides of the sash serve to exclude draughts and prevents rattling. I prefer
to hinge strips to all four sides of the frame but if necessary the top strip may be
dispensed with to facilitate fitting Venetian or other blinds.
When two sashes are pivoted in a single frame I prefer to hinge a strip of wood
to one sash which closes the central division between the two sashes when they
are closed.
The sashes thus mounted can be turned completely round on their pivots so
that both sides of the glass can be easily and conveniently cleaned from the
interior of the room.
Any convenient number of sashes can be mounted in a similar manner in a
single window frame.

A Revolving Window.
I, ROBERT FLINT, of The Lorne Hotel, Rhyl, North Wales, Hotel Proprietor,
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 a revolving window and, the objects of my invention
are to enable both sides of the window panes to be cleaned from the inside of a

page_text: room; to check draughts and vibration during stormy weather; to enable the
window sash to be readily removed from its frame; and to dispense with the cords
and weights usually employed to balance the sash.
According to my invention I pivot the window sash on pins on opposite sides
of the sash and these pins fit into slots or bearings in or on the frame in such
manner that the sash can be readily turned completely round on its pivots and
when open, the pivots can be released from their bearings and the sash lifted out.
Any suitable means may be employed to lock the sash partly open or in any
other required position.
I hinge wooden or other strips to the frame and these strips when closed over
the sides of the sash serve to lock it and exclude draughts and prevent rattling.
I prefer to hinge strips to all four sides of the frame but if necessary the top strip
may be dispensed with to facilitate fitting Venetian or other blinds.
When two sashes are pivoted in a single frame I prefer to hinge a strip of wood
to one sash which closes the central division between the two sashes when they
are closed.
The sashes thus mounted can be turned completely round on their pivots so
that both sides of the glass can be easily and conveniently cleaned from the
interior of the room.
In the accompanying sheet of drawings-
Fig. 1 is a front elevation of a revolving window constructed and arranged
according to my invention, Fig. 2 a sectional side elevation, on the line A B,"
Fig. 1, and Fig. 3 a sectional side elevation of Fig. 1 but showing the window.
sashes open instead of closed.
In these views, 2 denotes the casing or window frame in which are fitted two
window sashes pivoted on pins fitted into slots or bearings in or on the frame
in such manner that each sash can be readily turned completely round on its
pivots, and when open the sash can be raised slightly and lifted out of the frame,
the pivots passing through slots 5 in the frame, see Fig. 2.
To secure each window sash 3 in its place I hinge two wooden or other strips 6
to each side of the frame, a strip 7 to the top of the frame, and a strip 8 to the
bottom of the frame; these hinged strips besides securing each sash, serve to
exclude draughts and prevent rattling but in place of the hinged strips I might
employ any other suitable means for securing the sashes.
To the lower sash I prefer to hinge a strip of wood or its equivalent 9, which
covers the joint between the two sashes,
The top strip 7 could be dispensed with to facilitate fitting Venetian or other
blinds and similarly the bottom strip 8 might be dispensed with if desired.
To open the lower sash the two side strips 6 are turned back upon their hinges,
as shown in Fig. 3 and the intermediate strip 9 is released from its fastening and
when this has been done the sash can be opened by turning it upon its pivots.
To clean both sides of the glass the sash can be turned completely round when
all the strips are turned back and also can be lifted out and removed, if required.
In a similar manner the upper sash or half of the window can be opened by
turning back the top strip 7 and side strips 6, and can also be turned completely 4
round or removed when open.
A convenient means for securing the upper sash when open consists of a small
metal plate 10 with a pin 11, this plate lies in a recess in the window frame and
is so pivoted that by pressing lightly with the finger upon its lower end the plate
will fall down into the position shown in Fig. 3 ready to receive a plate 12 5
pivoted to the upper sash at 13, this plate lies in a recess in the sash and can be
pulled down when the strip 6 is drawn back. In the bar 12 are several holes
any one of which can be placed over the pin 11 to secure the sash in an open
position as shown in Fig. 3; after the plates 10 and 12 have been returned to
their normal positions as shown in Fig. 1 the sash can be turned completely round 5
on its pivots 4.
In a somewhat similar manner the lower sash is secured in any desired open :

page_text: position, a bar 14 pivoted to the lower sash, has a number of holes in it any one
of which can be put over a pin 15 on the bottom strip 8, and to secure the bar 14.
when not in use a slotted projection 16 on it is passed' over and secured by a turn
button or its equivalent on the lower sash.
By my improved method of mounting window sashes the windows can be readily
cleaned on both sides from the inside of the room or building, the sashes can
easily be removed and further the use of sash cords and weights is entirely dis-
pensed with.
Any convenient number of sashes can be mounted in a similar manner in a
single window frame.
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:-
1. A window sash mounted on pivots so that it can be turned completely round
and lifted out if required in combination with hinged strips or their equivalents
for securing the sash in position, excluding draughts, and checking vibration,
substantially as herein set forth.
2. The general arrangement and construction of parts substantially as herein
described and as shown."
