IMPROVEMENTS IN SLIDING SASH FRAMES
Year: 1884

page_text: I, WILLIAM BENJAMIN CARNE, of Kingsand, in the County of Cornwall, Builder,
do hereby declare the nature of said invention for IMPROVEMENTS IN SLIDING
SASH FRAMES, to be as follows:—
The object of my invention is to construct the frames of sliding sashes in such a
manner that the sashes may be removed therefrom, and brought into a room for
the purpose of repairs, cleaning, painting or other purposes, and re-adjusted in their
frames without the aid of a mechanic, or any tools, and without removing either
stops or beads.
For the purposes of my Invention I cut half the pulley stiles, including the
parting beads, which latter, according to my Invention, are fixed to the pulley
stiles and pocket pieces, from the inside lining, towards the front of the frame, and
two inches longer than the bottom sash. These pocket pieces are hung with loose
butt hinges to allow the pockets to turn inwards towards the back lining of the
frame in order to allow of the sashes being taken out of the frame, with ease, the
said pocket pieces being, closed and fastened with flush bolts.
In order to take out and replace the sash lines or cords, holes are made in the
stiles of the sash to receive knots on the sash lines, and grooves are made in the
sides of the sash in the usual way, into which the sash lines are inserted.
.
By hanging the pocket pieces with loose butt hinges, they may be easily
unhung, so as to take out the sash weights, if required.
In the bottom sash a slot is cut on the outside part of both the stiles, and solid
pieces, fixed to the pocket pieces, fill up these slots when the sash is closed; these
slots allow the pocket pieces to be opened and closed.
The inside linings are also slightly hollowed on the back part to allow the
pocket pieces to turn round.

I, WILLIAM BENJAMIN CARNE, of Kingsand, in the County of Cornwall, Builder,
do hereby declare the nature of said invention for IMPROVEMENTS IN SLIDING
SASH FRAMES, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference being had
to the accompanying drawings, and to the letters and figures marked thereon, that
is to say:
The object of my Invention is to construct the frames of sliding sashes in such a
manner that the sashes may be removed therefrom and brought into a room for
the purpose of repairs, cleaning, painting or other purposes, and re-adjusted in
their frames without the aid of a mechanic, or any tools, and without removing 1
either stops or beads.
Fig. 1 is an outside elevation of the window, the lining being removed to shew
the slot cut in the sash.
Fig. 2 is the front of the pulley stile with the pocket closed and bolted, the sash
being removed.
Fig. 2 is a horizontal section taken on the line a, a, of Fig. 2.
Fig. 3 shews the pulley stile with the pocket open..
.
Fig. 3 is a horizontal section taken on the line y, y, of Fig. 3.
Fig. 4 shows the pocket opened with the sash moved on one side into the pocket
hole to clear the bead on the opposite side.
Fig. 4* is a horizontal section taken on the line w, w of Fig. 4.
Fig. 5 is an inside elevation with the lining removed and the pocket closed.
Fig. 5 is a horizontal section taken on the line v, v, of Fig. 5.
For the purposes of my Invention I divide the pulley stiles, including the
parting beads, in two portions a, b, which beads c, according to my invention, are
fixed to the pulley stiles and pocket pieces and project from the inside lining
towards the front of the frame; the portions 6 form the pocket pieces. These
pocket pieces bare hung with loose butt hinges e to allow the pockets to turn
inwards towards the back lining of the frame, in order to allow of the sashes being
taken out of the frame with ease; the said pocket pieces are closed and fastened
by flush bolts f.
In order to take out and replace the sash lines or cords, holes are made in the
stiles of the sash to receive knobs on the sash lines, and grooves are made in the
sides of the sash in the usual way into which the sash lines are inserted.
By hanging the pocket pieces with loose butt hinges they may be easily unhung
- BO as to take out the sash weights if required.
In the bottom sash a slot g is cut on the outside part of both the stiles, and solid
pieces h fixed to the pocket pieces fill up these slots when the sash is closed; the
slots allow the pocket pieces to be opened and closed.
The inside linings are also slightly hollowed on the back to allow the pocket
pieces to turn round.
To take out the sashes the following means are adopted.
When the window is closed and fastened as in Fig. 1, the sashes must be
unfastened, the top sash pulled down, so as to raise the weight clear of the pocket
piece b. The bottom sash is then partially raised and the flush bolts on the pocket
piece on one side of the frame unfastened. The sash weight of the bottom sash on
that side must then be held up by the cord clear of the pocket piece which must
then be pushed back on its hinges into the socket hole, as in Figs. 3 and 3*, the
weight must then be released, the sash drawn down and moved on one side into

page_text: the pocket hole, as in Fig. 4, which immediately clears it from the beads on the
opposite side, the sash can then be withdrawn from the frame and the cord detached.
The top sash can also be moved into the same opening and detached in like
manner,
On re-adjusting the sashes the top sash must be first attached to the weights,
put into the frame and kept down, then the cords attached to the bottom sash;
the sash weight on the side in which the pocket is open must again be held up
close to the pulley to clear the pocket piece while the sash is raised and the pocket
closed, it can then be released and the flush bolts fastened, which makes the
window frame and sashes complete and secure as any ordinary window.
Both pulley stiles are constructed in the same manner so that no difficulty may
be experienced in attaching new sash cords.
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,
The construction of sliding sash frame substantially in the manner herein
described, and as shewn in the drawings, and for the purposes set forth.
Dated this 16 day of October 1884.
