Improvements in Windows.
JAMES THORNELOE, 20, Johnstone Street, Ladywood, Birmingham, in the County of
Warwick, Clerk of Works, do hereby declare the nature of this invention to be as
follows:-
The invention relates to certain improvements for opening and closing windows,
both inwards, and outwards. The invention may be a sliding sash, (or sashes,) with
a casement, (or casements,) fitted within the sliding sash, or the casement,
(or casements) may be fitted within a fixed frame, without the sliding sashes. The
casement may be centred, or pivotted, at the side, or in the centre, either vertical,
or horizontal, and open inwards, or outwards.
The four sides, or edges, of the casement are fitted with interlocking tongues,
which are actuated by cams. The casement stay is arranged to secure the casement,
either inwards, or outwards.

I, JAMES THORNELOE, of 20, Johnstone Street, Ladywood, Birmingham, in the
County of Warwick, Clerk of Works, do hereby declare the nature of this invention
and in what manner the same is to be perforined, to be particularly described and
ascertained in and by the following statement:-
The invention relates to certain improvements for opening and closing windows
both inwards and outwards.
The invention may be carried into effect in the form of a sliding sash, or sashes,
within which is fitted a casement or casements of similar section on all four sides or
edges, so arranged that it, or they, will open either inwards or outwards.
The invention may also be carried into effect by a casement, or casements, fitted
into a fixed solid window frame and of similar section on all four sides or edges of the
casement, so arranged that it, or they, will open inwards or outwards.
The invention may be applied to existing sash frames, or to fixed solid frames or
other openings.
The invention may be carried out partly in wood, and partly in metal, or the whole
may be carried out in metal.
The following may be described by way of illustration, though I do not confine
myself to these, or any particular devices for effecting the object set forth-
Fig. 1. is a sectional plan of a portion of a pair of sashes and frame, shewing one
casement released for opening, and the other casement interlocked, i.e., closed.

page_text: Fig. 2. shews a corresponding arrangement to Fig. 1. but with different devices for
carrying it out.
Fig. 3. is a sectional plan of a portion of a fixed solid frame, with the casement
interlocked, i.e., closed.
Fig. 4. is a sectional plan of a portion of a fixed solid frame, with the casement
released for opening.
Fig. 5. is a sectional plan of a portion of a stone window, with the casement
interlocked, i.e., closed.
In Fig. 1. and Fig. 2. A is part of a frame for sliding sashes, B. B. are the stiles of
the top and bottom sashes, C. C. are the fixed solid metal frames for the casements,
within which the interlocking tongnes D. D. are hinged or pivotted, by some known
form of hinge or pivot, E. E. are the opening frames of the casements, D'. Fig. 1 and
Fig. 2. shews the interlocking tongue withdrawn into the fixed solid frame, to allow
the casement to open inwards and outwards, as indicated by the arrows.
In Fig. 3. and Fig. 4. F. shews part of a fixed solid window frame, the other parts
and the letters of reference are the same as in Fig. 1. and Fig. 2.
In Fig. 5. H. shews part of a stone window, the other parts, and the letters of
reference are the same as in Fig. 1. and Fig. 2.
The four inner sides or edges of the sliding sash, or casement frame, are fitted with
the interlocking tongues, of similar section, which interlock with each other, and into
the corresponding edges of the casement, these interlocking tongues are actuated or
withdrawn, by one or more cams, the said cams being put in operation by studs,
buttons, or levers of some known form.
The casement may be centred, pivotted, or hinged, near the side, in the centre, or
at any intermediate point, when opening inwards, and outwards, vertically.
The casement may be centred, pivotted, or hinged, near the top, or bottom, at the
centre, or at any intermediate point, when opening inwards and outwards,
horizontally.
The casement stay is constructed to secure the casement when opened either
inwards or outwards, by means of a hinged swivel joint, Fig. 6. and Fig. 6 a.
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:-
First. Casements of similar section on all four sides or edges, fitted within the
sliding sashes of a window, the casements opening inwards, and outwards.
Second. Casements of similar section on all four sides or edges, fitted within fixed
solid window frames, the casements opening inwards, and outwards.
Third. Casements fitted with tongues of similar section, on all four sides or edges
of the casement, that interlock with each other, and interlock the casement, and the
frame, the said tongues being actuated or withdrawn by one or more cams.
Fourth. Casements that are centred, pivotted, or hinged, near the side, at the
centre, or at any intermediate point, when opening, vertically, inwards and outwards.
Fifth. Casements that are centred, pivotted, or hinged, near the top, or bottom, at
the centre, or at any intermediate point, when opening horizontally, inwards and
outwards.
Sixth. A casement stay that will secure the casement, by means of a hinged swivel
joint, when the casement is opened inwards or outwards.
