PROVISIONAL SPECIFICATION.
Improved Means for Facilitating the Removal of Window-sashes
from their Frames and the Replacing of the same therein.
I, ALFRED CARTER, of 4 Glenwood Road, West Green, Tottenham, in the
County of Middlesex, Carpenter, do hereby declare the nature of this invention to
be as follows:-
:-
My invention relates to improved means for facilitating the removal of window-
sashes from sash-frames and the replacing of the same therein, and my said
invention obviates the liability to accidents during the cleaning or glazing of the
windows and increases the facility and rapidity with which these operations may be
performed.
An important feature of my said invention is the construction of the pulley-stile
at one side of the sash-frame in such a manner that a portion of the said stile is
readily removable, and, when removed, will leave a recess or cavity into which the
sashes can be successively pushed to permit them to pass the bead or beads on the
opposite side of the sash-frame. By this means I am enabled, without otherwise
altering the construction and without changing the appearance of the sashes and
sash-frame, to provide for the removal and replacing of the sashes with great
facility and in a very short space of time.
I also provide for the detachment of the sashes from the sash-lines, and for the
retention of the said lines, during the operation of cleaning or glazing the window,
in a convenient position for the said lines to be again secured to the sashes, thus
preventing the running down of the sash-weights and the consequent difficulty of
again getting hold of the sash-lines.
In carrying my said invention into practice, I find it advantageous to provide
the sash-frame at one side thereof with a pulley-stile which term a "double
pulley-stile," and which is divided vertically, the plane of division being at right
angles to the sash. The inner portion of this double pulley-stile is firmly
secured in the sash-frame and has a suitable aperture formed in it to permit access
to the sash-weights. The outer portion of the said pulley-stile has secured therein
the parting bead for guiding the sashes, and is cut into several lengths or sections,
some of which are permanently fixed in the sash-frame; the other lengths or
sections of the outer portion of the pulley-stile are preferably connected together
by one or more hinge-joints so that they can be folded as required, and, instead of
being permanently fixed in the sash-frame, this hinged portion of the pulley-stile is
so arranged that it can be readily removed and replaced. This removable portion
of the pulley-stile must be of somewhat greater length than the longer sash of the
window, so that it extends a short distance above the top of the lower sash when
the window is closed. In the case of windows of considerable width, it is only
necessary to provide the said removable portion of the pulley-stile with one hinge-
joint. When, however, the window is a narrow one, it may be necessary to make
the said removable portion with two hinge-joints, to permit the same to be folded in
the operations of removing it from and replacing it in the sash-frame.
I can, if
desired, provide suitable means for temporarily securing in place the said removable
portion of the pulley-stile. For instance, I provide a pin which is passed through
the sash-frame and into the said renovable portion of the pulley-stile.
The upper end of the removable portion of the said pulley-stile is preferably
bevelled so that it can be inserted beneath the correspondingly bevelled lower end
of the adjacent fixed portion of the said pulley-stile. The parting bead serves as
a convenient handle in the operations of removing and replacing the movable
portion of the pulley-stile. I prefer to secure the said parting bead therein by

page_text: means of glue, and it may be advantageous to further secure it at its lower end by
means of a screw.
The pulley-stile at the opposite side of the sash-frame may be of the ordinary
construction.
The sash-lines may be secured to the sashes in any convenient manner so that
they can be readily connected therewith and disconnected therefrom. I find it
advantageous to provide the sash-line with an eye or ring adapted to engage with a
hook which is firmly secured within the groove in the sash. I sometimes make
this hook with an eye or loop at its lower end, through which is passed a pin
secured in the sash; the screws employed for securing the hook to the sash are
thus wholly or partially relieved from the weight of the sash.
I also provide suitable hooks which are secured in the sash-frame, and to which
the sash-lines may be connected after their disengagement from the sashes.
In addition to the advantages above enumerated, my invention affords the
further advantage that the window-sashes can be removed and the sash-lines
renewed without the necessity for taking off the beads of the sash-frame and cop-
sequently without liability to injury of such beads by the tools used in the
detachment of the same.
It is evident that my improvements can be conveniently applied to existing
windows, and in cases where the pulley-stile is of sufficient thickness, I may simply
cut out a portion of the same and fit the removable piece therein, instead of making
the said pulley-stile double as above mentioned.
It is obvious, moreover, that instead of connecting the parts of the removable
piece by means of a hinge-joint, I may, if desired, use them separately, the lower
part being first removed so as to permit the sliding downward of the other part to
bring it clear of the sashes.

COMPLETE SPECIFICATION.
Improved Means for Facilitating the Removal of Window-sashes
from their Frames and the Replacing of the same therein.
I, ALFRED CARTER, of 4, Glenwood Road, West Green, Tottenham, in the
County of Middlesex, Carpenter, 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 improved means for facilitating the removal of window-
sashes from sash-frames and the replacing of the same therein, and my said
invention obviates the liability to accidents during the operations of cleaning and
glazing windows, and increases the facility and rapidity with which these operations
may be performed.
An important feature of my said invention is the construction of the pulley-stile
at one or the other side of the sash-frame in such a manner that a portion or
portions of the said stile may be readily removed, so as to leave a recess or cavity
into which the sashes can be successively pushed to permit them to pass the bead
or beads on the opposite side of the sash-frame. By this means 1 am enabled,
without otherwise altering the construction and without changing the external
appearance of the sashes and sash-frame, to provide for the removal and replacing
of the sashes with great facility and in a very short space of time.
I also provide for the detachment or uncoupling of the sashes from the sash-lines,
and for the retention of the said lines (while the sashes are disconnected there-
from) in a convenient position for the said lines to be again secured or coupled
to the sashes, so as to prevent the running down of the sash-weights and the
consequent difficulty of again getting hold of the sash-lines.

page_text: In the accompanying drawings have shown now my said invention may ve
conveniently and advantageously carried into practice.
Figure 1 is a front elevation, partly in vertical section, showing a window-frame
having my improvements applied thereto.
Figure 2 is a similar view showing the parts in a different position.
Figure 3 is a vertical transverse section, the sashes being removed.
Figure 4 is a horizontal section on the line c, r, Figure 1, illustrating the method
of removing the lower sash from the sash-frame.
Figure 5 is an edge view, and
Figure 6 a front elevation, partly in vertical section, showing a portion of the
lower sash.
A is the sash-frame; B, B' are the sashes. The sash-frame A is provided at
one side thereof with a pulley-stile C, C', which I term a double pulley-stile, and
which is divided vertically, the plane of division being at right angles to the sash.
The inner portion of this double pulley-stile is firmly secured in the sash-
frame A and has a suitable aperture C² formed in it to permit access to the
sash-weights. The outer portion C of the said pulley-stile has secured therein
the parting bead D for guiding the sashes, and the said outer portion C³ is cut
into several lengths or sections 1, 2, 3, 4 and 5. The sectious 1 and 5 are
permanently fixed in the sash-frame A; the other lengths or sections 2, 3 and 4
of the outer portion C¹ of the pulley-stile are connected together by hinge-
joints E, E, so that they can be folded as required for the purpose hereinafter
specified, and, instead of being permanently fixed in the sash-frame, this hinged
portion of the pulley-stile is so arranged that it can be readily removed and
replaced. The said removable portion of the pulley-stile must be of somewhat
greater length than the longer sash of the window, so that, when it is removed,
either sash may be pushed laterally until it comes in contact with the fixed portion
of the said double pulley-stile as indicated in Figure 4. In the case of windows of
considerable width, it is only necessary to provide the said removable portion of
the pulley-stile with one hinge-joint so that it may be folded to permit of its being
pulled down until its upper end is clear of the upper sash. When, however, the
window is a narrow one, it may be necessary to make the said removable portion
with two hinge-joints as shewn, so that the same may be folded in the manner
indicated in Figure 2, in the operations of removing it from and replacing it in the
sash-frame. I can, if desired, provide suitable means for temporarily securing in
place the said removable portion of the pulley-stile. For instance, I provide a
pin F which is passed through the sash-frame and into the said removable portion
of the pulley-stile. Or I provide a push-button, a bolt or other suitable fastener
in the face of the lower end of the removable portion of the pulley-stile.
The upper end of the removable portion of the said pulley-stile is preferably
bevelled as shown, so that it will fit in beneath the correspondingly bevelled lower
end of the adjacent fixed portion 1 of the said pulley-stile. The parting bead D
serves as a convenient handle whereby the movable portion of the pulley-stile may
be held in the operations of removing and replacing the same.
"I usually secure,
the said parting bead in the pulley-stile by means of glue; it may be advantageous
to further secure the said bead at the lower end of the removable portion of the
said pulley-stile by means of a screw.
The pulley-stile at the opposite side of the sash-frame may be of the usual or
other suitable construction.
The sash-lines may be secured to the sashes in any convenient manner so that
they can be readily connected therewith and disconnected therefrom. I find it
advantageous to provide each sash-line G with an elongated eye or ring G adapted
to engage with a hook H which is firmly secured within the groove B in the sash.
I sometimes make this hook with an eye or loop at its lower end through which is
passed a pin secured in the sash; the screws employed for securing the hook to the
sash are thus wholly or partially relieved from the weight of the sash.
I also provide suitable hooks J which are secured in the sash-frame A and to

page_text: which the sash-lines G may be connected after their disengagement from the sashes.
These hooks are preferably so constructed and arranged that they do not project
from the surface of the frame A.
The removal of the sashes is effected as follows, uiz. The lower sash B is first
raised, and the removable portion 2, 3, 4 of the pulley-stile C, C is taken out by
folding it as indicated in Figure 2 and then sliding it downward until its upper
end is clear of the sashes. The lower sash is then pulled down and moved laterally
into the space or cavity left by the removal of the said portion of the pulley-stile.
This movement disengages the lower sash from the beading at the opposite side of
the sash-frame A, as shewn in Figure 4, so that the said sash can be easily taken
out of the frame. The said sash is then uncoupled from the sash-lines G and the latter
are coupled to the hooks J. The upper sash B is then pulled down and removed
in like manner from the sash-frame A, and is uncoupled from its sash-lines, which
are then also coupled to the hooks J. To replace the sashes in the frame, these
operations are performed in the reverse order.
It is evident, therefore, that my invention enables the removal and replacement
of window-sashes to be very easily and expeditiously effected, even by unskilled
persons.
My improvements can be conveniently and advantageously applied to existing
sashes and sash-frames without disfiguring the same.
In addition to the advantages above enumerated, my invention affords the further
advantage that the window-sashes can be removed and the sash-lines renewed
without the necessity for taking off the beads of the sash-frame, and consequently
without liability to injury of such beads by the tools required in the detachment of
the same.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
First. The method of providing for the ready removal and replacement of
window-sashes, by making a portion or portions of one of the pulley-stiles
removable, substantially as hereinbefore described.
Second. A sash-frame in which two or more readily removable sections of one of
the pulley-stiles are connected by hinge-joints, for the purpose above specified.
Third. A sash-frame constructed with a double pulley-stile the outer portion
whereof is divided into lengths or sections some of which are connected by hinge-
joints and are readily removable from the said frame, substantially as, and for the
purpose, above specified.
I
Fourth. The above described improvements whereby provide for the detach-
ment or uncoupling of the sash-lines from a window-sash and for the retention of
the said lines in a convenient position for again coupling them to the sash, for the
purpose specified.
Fifth. A sash-frame provided with sashes and having my improvements applied
thereto substantially as described with reference to the accompanying drawings, for
the purposes specified.
