IMPROVEMENTS IN THE METHOD OF SECURING SLIDING WINDOW SASHES AND SHUTTERS, AND IN THE CONSTRUCTION OF FASTENERS. THEREFOR
Year: 1885

page_text: I, WALTER POPE, of Baston House, Netherhall Terrace, Hampstead, in the
County of Middlesex, Architect and Surveyor, do hereby declare the nature of my
Invention for "IMPROVEMENTS IN THE METHOD OF SECURING SLIDING WINDOW
SASHES AND SHUTTERS, AND IN THE CONSTRUCTION OF FASTENERS. THEREFOR,' to
be as follows:-
""
The object of my invention is to effect improvements in the method of securing
sliding window sashes and shutters, by means of improved fasteners.
My improved fastener consists of two plates of metal, hinged together like
"butt" hinges. One plate is fixed to the stile of the upper sash, near its lower
end, and the other plate is free to revolve on the pin of the hinge in a horizontal
direction through an arc of about 90°. When the free plate is placed at right
angles to the fixed plate, such free plate projects across the top bar and stile of the
lower sash; but when the free plate is folded so as to "butt" against the fixed
plate, parallel thereto, the lower sash may be raised and the upper sash can be
lowered, without interruption.
The fixed plate is usually sunk into the stile, so as to be flush with its surface,
or deeper still so that both plates may be flush when folded together.
I prefer to fit both stiles of the upper sash with a fastener; one right hand and
the other left hand.
The loose plate is usually made in an ornamental manner, and is sometimes fitted
with springs which retain it in the position of "locked " or " unlocked."
In some cases I fit two or more of my "butt hinge" fasteners to each stile of an
upper sash, by which arrangement the window may be secured in an open position,
for purposes of ventilation, and yet be secured against intruders.
Corresponding to the above mentioned fasteners, I fit plates in a horizontal
position upon the top rail of the lower sash, to receive the lower edges of the free
plates of the fasteners. These horizontal plates may be plain, or fitted with dove-
tail appliances to enter suitable notches in the fasteners; or may have folding
plates, springs, snaps, bolts, buttons or buckles, in order to secure the free plate of
the fastener ut right angles to the fixed plate, when the window is fastened.
It is obvious that, with slight modifications, my said invention may be applied to
sashes and shutters, whether sliding vertically, horizontally or diagonally.

I WALTER POPE of Baston House, Netherhall Terrace, Hampstead in the County
of Middlesex Architect and Surveyor, do hereby declare the nature of my said
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement: -—
The object of my invention is to effect improvements in the method of securing
sliding window sashes and shutters, by means of improved fasteners.
My improved fastener consists of two plates of metal, hinged together like
"butt" hinges. One plate is fixed to the stile of the upper sash, near its lower
end, and the other plate is free to revolve on the pin of the hinge in a horizontal
direction through an arc of about 90°. When the free plate is placed at right
angles to the fixed plate, such free plate projects across the top bar and stile of the
lower sash but when the free plate is folded so as to "butt" against the fixed
plate, parallel thereto, the lower sash may be raised and the upper sash can be
lowered, without interruption.
The fixed plate is usually sunk into the stile, so as to be flush with its surface, or
deeper still so that both plates may be flush when folded together.
.
I prefer to fit both stiles of the upper sash with a fastener, one right hand and
the other left hand.
The loose plate is usually made in an ornamental manner, and is sometimes fitted
with springs which retain it in the position of "locked' or "unlocked."
In some cases I fit two or more of my "butt hinge" fasteners to each stile of an
upper sash, by which arrangement the window may be secured in an open position,
for purposes of ventilation, and yet be secured against intruders.
Corresponding to the above mentioned fasteners, I fit plates in a horizontal
position upon the top rail of the lower sash, to receive the lower edges of the free
plates of the fasteners. These horizontal plates may be plain, or fitted with dove-
tail appliances to enter suitable notches in the fasteners; or may have folding
plates, springs, snaps, bolts, buttons or buckles in order to secure the free plate of
the fastener at right angles to the fixed plate, when the window is fastened.
It is obvious that, with slight modifications, my said invention may be applied to
sashes and shutters, whether sliding vertically, horizontally or diagonally.
And in order that my said invention may be more particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1 is a front view of the fastener a b-Fig. 2 is a plan of the plate p-
Fig. 3 is a plan view of the invention fitted in position and ready to be fastened;
and Fig. 4 is a similar view, on the right hand side, shewing the same fastened.
a is that portion of the butt fastening which is screwed to the upper sash stile,
as shewn in Figs. 3 and 4. b is the free plate which swings on the pin c. d is an
opening cut into the plate b as shewn. The form of this opening coincides with the
sectional form of the raised tongue or plate e.

page_text: When the plate 6 is placed in the position shown in Fig. 3, both sashes are free
to open, but when placed at right angles, as shewn in Fig. 4, the plate b crosses
the upper bar of the lower sash, and effectually secures the window. f is a
locking bar far more effectually securing the plate b when in the position shewn
in Fig. 4.
The knob k of the bar ƒ is pressed outwards by the spring 9. h is the pivot on
which f works.
When fastening the window, the plate f takes the position shewn by dotted
lines in Fig. 3, and when it is necessary to unfasten the window the knob k is
pressed inwards to the position shown by the samo dotted lines in Fig. 3, which
operation frees the plate b. mm are the parting beads, n n the upper bar of the
lower sash, o o the lower bar of the upper sash, and p p the stiles (in section) of
the upper sash.
The locking together of the tongue e and plate b prevents the rattling of the
sashes, and draws the meeting bars together.
In fitting up my invention various modifications may be adopted; thus, the
shape of the space d, and the sectional form of the tongue e, may be varied; or
the tongue e and space & may be omitted altogether; and the locking bar f may
be otherwise formed and operated, and, in some cases, be altogether dispensed
with; the plate shewn in Fig. 2 would then be used merely to prevent abrasion of
the wood.
I also sometimes fit additional plates ab upon the stiles of the upper sash at
various distances apart as before mentioned, by which means the window may be
left open at suitable positions for ventilation and secured against intruders.
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. The method of fastening and securing window sashes by means of hinged
fasteners or folding plates ab placed on one or both sides of the upper sash,
substantially as herein before described and shewn on the drawings.
2. In combination with the fasteners a b, the use and application of plates p,
with or without the tongue e, and locking bar for either of them, substantially as
and for the purposes herein before described and shewn on the drawings.
3. The means whereby windows may be prevented from rattling, and the
additional security afforded by the tongue e fitting into the space d with or
without the locking bar f substantially as herein before described and shown on
the drawings.
4. The manufacture of the several and respective parts of apparatus, and the use
of the same, as and for the purposes aforesaid substantially as herein before described
and shewn on the drawings.
5. The general construction arrangement, and combination of the several and
respective parts, together forming my improvements in the method of securing
sliding window sashes and shutters, and in the construction of fasteners therefor,
substantially as hereinbefore described and shewn on the drawings,
