I, JOHN BARTON MARSHALL, of Fresno, County of Fresno, California, U.S.A.,
Inventor, do hereby declare the nature of this invention to be as follows:-
This invention relates to windows; the object of the invention being to pro-
vide simple means whereby the danger occasioned by a person standing on the
sill or leaning out of a window for the purpose of cleaning it on the outside, is
obviated.
By this invention the beading which retains the sashes in position is severed
at a point about level with the top rail of the sash so that the lower portion can
be readily removed; the upper and lower sections being capable of being united
in any suitable way, such as by means of a metal plate secured to each part by
screws.
At points near the upper rail of the lower sash, and near to the bottom rail
thereof, respectively, horizontal grooves are cut to enter vertical grooves in the
sash-ways; the horizontal grooves being made capable of being closed by means
of turn-buttons or the like.
The sash has projecting pins which coincide with the horizontal grooves and
are reciprocable in the vertical grooves.
When the upper pins are brought opposite the upper horizontal grooves the
sash may be swung inwards around the lower pins which remain in the vertical
grooves and form pivots. When, however, the lower pins are raised opposite
to the lower horizontal grooves, the sash can be removed; the weight cords
having been previously detached in both cases.
In an alternative form, the side bars of each sash are fitted, near their lower
ends, with a metal plate, sunk in flush, and having a normally outwardly pro-
jecting spring-tongue carrying a pin having its extremity bevelled after the
manner of a latch. When the sashes are in their lowest positions the pins
spring into apertures recessed flush in the sash-ways, and the sashes can be swung
inwards around said pins. When, however, the sashes are vertical the bevelled
points of the pins will ride out of the apertures in the plates and permit the
sashes to be raised.

page_text: same is to be performed, to be particularly described and ascertained in and by
the following statement:-
My invention relates to an improvement in the construction of windows, and
has for its object to provide a simple and comparatively inexpensive method
which permits of the sashes being readily released so as to enable them to be
swung downward and inward to afford convenient access to their outer faces for
cleaning them from the inside, further, to enable the sashes to be easily entirely
removed or detached from the frame, and, further, to provide for the sash cords
being easily detached from or connected to the sashes when desired.
Reference being had to the drawings:

tion, the position of one of them after being swung downwards and inwards being
indicated in dotted lines.

The numeral 1 indicates a window frame or casing having at its opposite sides
vertical grooves 2 and 3 forming ways for and receiving projections or studs 5
and 6 fixed in both the upper and lower sashes 7 and 8, and the said vertical
grooves or ways are intersected by horizontal grooves or ways り
and 10, their distance apart coinciding with that of the studs
and 6, forming entrances to the vertical grooves and situated, the one a short
distance below the top rail of the bottom sash and the other a greater distance
above the bottom rail of the bottom sash. The horizontal grooves 9 and 10 are
normally closed at their outer ends by turn-plates 11 revolubly secured to the
outer face of the window frame. The bead or strip is divided into an upper and
lower section 12 and 13 at a point some distance above the centre of the window
frame, the meeting ends being formed with registering kerfs for engagement by
a locking web 14 projecting rearwardly from a plate 15 adapted to be secured by
screws to the upper or fixed section 12 of the bead or strip.
In
Sash cords 17 pass over pulleys 18 to the weights in the usual manner.
the upper side portions of the sashes 7 and 8 are formed grooves 19 enlarged at
their lower ends for the reception and fixing of a retaining hook 20. The ends,
opposite to the weights, of the sash-cords 17 pass within the grooves 19, the
knot 21, or other stop, at their extremities being passed through and under the
grooved hook 20 so that they are retained in such position. When it is desired
to release the sash cords from the sashes the knot 21 is released from the grooved
hook 20 and temporarily attached to a suitable hook 22 fixed for this purpose to
the window-frame.
In operation, the lower section 13 of the bead being withdrawn from connection
with the web 14 of the plate 15 and the sash cords detached from the grooved
hooks 20 the turn-plates 11 of the grooves are opened, and the sash 8 being
the sash can then be swung
raised until the pins 5 coincide with the grooves
inward and downward upon the pins 6 as pivots, and supported in a level posi-
tion on the sill and any suitable supplementary support. The upper sash 7 can
then be lowered to register its unner pins with the upper grooves in similar
manner and can be laid in horizontal position upon the lower sash 8, the height

page_text: of the groove 10 above the sill being sufficient to allow of this or of its entire
withdrawal above the sash 8 if necessary.
In the alternative form shewn in Figs. 7 and 8 the upper and lower sashes i
and 8 near the bottom of each of their sides are provided with a box 22" let in
flush with the said sides and having a spring tongue 23 formed integral with the
said box or attached to the same in any convenient manner. The spring
tongue 23 at its extremity is provided with a round pin 24 chamfered as to its
end in latch form. In normal position the spring-tongue 23 is level with the side
surface of the sash, the pin 24 projecting beyond such surface. Within each of
the sash-ways 25 and 26 and let in flush with the outer surfaces thereof is a
plate 27 provided with a groove 28, having inclined ends 28", into which the
pin 24 can readily enter.
When the lower sash 8 is closed the pins 24 enter and rest within the grooves 28,
and when the sash is raised, the spring tongues and pins assume the position
shewn in dotted lines (Fig. 7), the ends of the pins then travelling on the outer
surface of the sash ways 26. It will be understood that the spring tongues and
pins readily assume this position owing to the chamfered ends of the pins meet-
ing and rising up the inclined ends 28" of the grooves 28. The pins 24 of the
upper sash 7 always engage with and travel on the outer surface of the sash
ways 25 until such time as it is desired to clean or remove the said upper sash.
When it is desired to lower the sashes inwardly for cleaning the outside surfaces
of the glass the operation is thus performed:-The lower section 13 of the bead
or strip is removed as hereinbefore described and the lower sash weights detached.
The lower sash S can then be lowered inwardly, upon the pins 24 as a pivot, and
rested upon the sill. The lower halves of the parting strips 29, which are
bisected, are then detached, the upper sash lowered, its weights detached, and
when it is further lowered until its pins 24 register with the corresponding
grooves 28 in the sash-way 25 it can be turned inwardly to rest on the bottom
sash 8, its plates 27 being set at such height in the sash-way as to allow of this.
Alternatively the upper portions of the parting strips 29 may be removed, in which
case the upper sash 7 can be pulled over to travel down the sash-way 26, and
in this case no grooved plates are provided in the sash-way 25, but those in the
sash-way 26 are elongated, as shewn in dotted lines in Figs. 7 and S. The
bisected parting strips 29 are joined by plates and screws or other convenient
method. Should it be desired to entirely remove the sashes from the frame it
will be readily seen that it is only necessary to raise them, when in vertical posi-
tion, a sufficient height to let the pins 24 leave the grooves 28 when they can be
withdrawn from the sash-ways.
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) In a window having vertical grooves arranged in pairs at opposite sides
in the frame thereof, upper and lower horizontal grooves located in said frame
respectively near the middle of the sash and above the lower ends of the vertical
grooves, and closed on the outside by turn-plates or the like, beads arranged
at opposite sides of the window-frame composed of upper and lower sections
having registering kerfs and T-shaped plates secured to the beads and having
their webs or flanges fitting the kerfs, the upper and lower sashes provided with
means whereby the sash-cords may be readily detached from or attached to the
sashes, the said sashes provided with rigid horizontal projections adapted to slide
in the vertical grooves and pass through the horizontal grooves, the lower projec-
tions of both sashes forming pivots adapted to permit the sashes to swing down-
wards and inwards to a horizontal position upon the bottom of the window frame
when the lower portion of the bead is removed, the sash cords detached from the
sashes, and the upper studs or projections disengaged from the vertical and hori-

page_text: zontal grooves substantially as described and illustrated in the drawings hereunto
annexed.
(2) In a window having vertical grooves arranged in pairs in opposite sides of
the frame thereof, beads arranged at opposite sides of the window frame composed
of upper and lower sections having registering kerfs and T-shaped plates secured
to the beads and having their webs or flanges fitting in the kerfs, parting strips
at opposite sides of the window frame bisected at or near their centre and joined
by means of plates and screws or the like, plates having grooves with inclined
ends within and flush with the sash-ways, upper and lower sashes provided with
hooks or like means whereby the sash cords may be readily detached from or
attached to the sashes, the upper and lower sashes provided at each side near
their bottom extremities with boxes let in flush with their side surfaces, the said
boxes provided with spring tongues carrying pins with chamfered ends the said
pins forming pivots adapted to permit the sashes to swing downwards and inwards
to a horizontal position upon the bottom of the window-frame after the lower
portion of the bead is removed, and the sash cords detached from the sashes,
substantially as and for the purposes hereinbefore set forth and illustrated in the
drawings hereunto annexed.
