Improvements in Window Sashes.
1, JOSEPH BERNARD COHEN, of No. 63 Washington Square South, City of New
York, State of New York, United States of America, Mechanic, 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
and accompanying drawings:-
My invention relates to improvements in window sashes, and it consists in the
construction, arrangement and operation of the parts hereinafter set forth.
In the drawings the same reference letters indicate the same parts in all the
figures.
Figure 1, illustrates an elevation of the invention the lower sash being swung
down and the upper one in normal position.
Figure 2, illustrates a sectional elevation of Figure one on the lineæ, æ, of Fig. 1,
partly broken away.
Figure 3, illustrates a sectional plan view on line y, y, of Fig. 1, with both sashes
in their normal position.
Figure 4, illustrates an enlarged view of the hinge between the sash and the
sliding strips, the latter being partly broken away.
Figure 5, illustrates the same as Fig. 4, the sash being let down.
Figures 6 & 7, are an elevation and vertical section respectively of a modified
construction of my invention.
A is the window casing. B, B' are the top and bottom sashes respectively. The
sashes are hinged or pivoted at C, C, C, C, to side strips D, D, D¹, D', which
slide in the sash rebates D2, D². E, E, E', E, are the window cords, they are
attached to the strips D, D, D', D', in the same manner that they are usually
attached to the side of the window sashes-excepting that they preferably cannot
be separated laterally from the upper part of the strips, on the contrary the
strips are confined to them at their upper ends either by the cords passing
through holes made in the body of the strips or by clips or other means to hold
the strips to the cords, so that when the sashes are turned downwardly on their
hinges or pivots as hereinafter described these strips will be held in the sash
rebates at their upper ends by the stress of the window cords on them as well as
by their confinement at the lower ends by the sashes. F, F, F, F¹, are catches
of any suitable construction, (the ordinary spring controlled spindle catch is shown
in the drawings); they pass through the sides of the sashes and enter recesses
or holes in the strips D, D, D, D₁, thus the sashes are held up parallel with the
strips and in proper closed position until the catches are released; the sashes may
then be swung downwardly and forwardly into the room where they may b
conveniently and easily cleaned.
In order that the upper sash may be manipulated in the same way that the
lower one is, the side strips D', D', of the upper sash are made so much wider than
the strips D, D, of the lower sash (see Fig. 3) that when the upper sash is pulled
down and its catches are released it may be turned downwardly and inwardly and
will move between the strips D, D, without striking them and attain a position
within the apartment the same as that described regarding the lower sash.
When my sashes are employed in dwelling houses or other places where it
would be objectionable on the score of loss of heat to open the entire window
space I construct them as shown in Figures six and seven, that is to say the
lower sash B is pivoted to the sliding strip D the same as in the cases above
described and illustrated but the upper sash is not hinged to the very bottom of
its sliding strips, on the contrary it is hung on pivots a, a, which pass through the
[ Prine A.1

page_text: sliding strips and enter the side of the sash a short distance above the bottom
thereof as at b, b,-and I cut out the window sill as at c so that the upper sash
may be drawn down so low that its upper rail will be below the bottom rail of
the other sash when their normal positions are reversed, and in this way after the
lower sash has been cleaned it may be pushed up to the top of the window frame
and the upper sash then being pulled fully down until its lower rail rests in the
cut out part of the sill marked c, then it may be tipped over inwardly, its upper
rail passing through below the lower rail of the other sash, and because it is
pivoted above the lower ends of the sliding strips it will not bind on the window
Bill while moving over. Thus it may be cleaned while the other sash which
is normally the lower one fills the upper part of the window frame and prevents
escape of heat.
As above set forth it will be seen that both of the sashes may be cleaned much
more easily, quickly and thoroughly than as they are now constructed and without
liability of falling of the person cleaning them. And that also bars shutters, or
wire netting which is frequently placed on the outside of windows present no
obstruction to the cleaning of the same because the window is moved away from
them into the room or apartment.
I do not limit myself to the details of construction shown since it will be obvious
to those who are skilled in this art that changes may be made therein and still the
essential features of my invention be employed.
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
olaim is :-
First. The combination in a window of a sash permanently pivoted at its lower
end to strips which slide in the rebates of the casing, catches which hold the upper
end of the sash to the strip and window cords attached to the strips, substantially
as set forth.
Second. The combination in a window of a plurality of sashes, each permanently
pivoted at its lower end to strips which slide in the rebates of the casing, the strips
for the upper casing being thicker than those of the lower casing, catches which
hold the sashes at their upper ends to their respective strips and window cords
attached to the strips, substantially as set forth.
Third. The combination in a window of a sash permanently pivoted at its lower
end to strips which slide in the rebates of the casing, catches which hold the upper
ends of the sash to the strips and window cords attached to the strips at or near
their upper ends, substantially as set forth.
Fourth. The combination in a window of a plurality of sashes each pivoted to
sliding strips which slide in the sash rebates of the casing, the pivots of the upper
sash being somewhat above the bottom of its sliding strips, window cords attached
to the strips, and a recessed sill into which recess the upper sash may descend
lower than the lower sash, substantially as set forth.
Dated this 19th day of June 1891.
