Improvements in window bases.
ERNST DUVAL, of 165, Sophia Street, in the City of Hamilton, in the
County of Wentworth, in the Province of Ontario, Dominion of Canada, Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
Reference being had to the accompanying drawing, in which,
Figure 1, is a face elevation of a window sash partially open, both at the top
and the bottom, a portion of the sash stop and sash at each side being broken
away in order to show the pivoted band, or chain pulleys, whereby the sash is
operated.
Figure 2, is a side elevation, a side of the window sash casing removed in
order to show the upper and lower parts of the sash brought into proximity and
then set at an angle to the casing.
Figure 3, is a sectional plan of Figure 1, showing the pivotal centres with
their chain wheels,
Figure 4, is a sectional plan of Figure 1, above and below the opened sash,
and
Figure 5, is a side elevation of the upper and lower sash showing their con-
nection with the chain pulleys by means of chains, which are shown in broken
lines, and which are similar on both sides, this view shows more explicitly the
operation of the opening and closing device.
To more fully comprehend the operation of this adjustable and swinging sash,
I will indicate the upper window sash by the numeral 2, the lower one by 3, the
window sash casing by 4, the inner vertical sides of said casing by 5, and the
side stops of the sash by 6.
The middle part of this casing has rigid pivots 8, projecting on each inner
side and in horizontal line on which revolves the double grooved pulleys 9, by
means of chains 10, and 12, the ends of which are attached to the upper, and
also to the lower ends of the sash, which when being adjusted, operate the chains
and pulleys.
These chains operate in conjunction with each other, all moving at the same
time when adjusting the sash, for instance when the lower sash is lifted, the
upper sash must of necessity come down at the same time, the opening at the
top and the bottom being the same. To accomplish this adjustment of the sash,
it will be observed, that in Figure 5, of the drawing is seen the manner of chain
attachment to the sash, namely one end of the chain 10, is attached to the upper
end of the upper sash 2, then downwards, and half round the pulley 9, then
upwards the other end of said chain is attached to the upper end of the lower
sash 3. The chain 12, passes half around the same pulley, in the adjoining
groove, and one end attached to the lower end of the upper sash 2, and the other
end attached to the lower end of the lower sash 3. These pul-
leys and chains being similar at both sides of the casing, all operating together,
each of the four chains in its own pulley groove. It will be perceived that the
inner edges of the sash, have vertical recesses 16, formed therein, in order to
allow the sash to operate freely past the pulleys.

page_text: To swing the sash, the upper and lower halves are brought into face proximity
and then swung as seen in Figure 2, of the drawing, to accomplish this, it is
necessary to divide the inner casings 5, the side stops 6, and the intermediate
guide strips 7, at the segmental lines 18, and 18. The sash can be moved one
past the other, when in a swinging position.

Improvements in Window Sashes.
I, ERNST DUVAL, of 165, Sophia Street, in the City of Hamilton, in the
County of Wentworth, in the Province of Ontario, Dominion of Canada, Manu-
facturer, 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 improvements in window sashes, which are capable
of vertical and swivel adjustment.
The objects of my invention are, first, to provide window sashes which are
capable of being opened at the top and the bottom, at the same time, in order to allow
little or more ventilation, second, to provide window sashes that are self sup-
porting and balanced, and third, to afford facilities for bringing the upper
and lower sash into face proximity, that the same may swivel on their side
pivots in order to give full ventilation, and also to afford accommodation for
window cleaning.
Reference being had to the drawings left with the Provisional Specification,
in which
Figure 1, is a face elevation of the window sashes partially open, both at the
top and the bottom, a portion of the sash stops and the sash at each side being
broken away, in order to show the pivoted cable or chain pulleys, whereby the
sashes are operated.
Figure 2, is a side elevation, a side of the window sashes casing being removed
in order to show the upper and lower parts of the sashes brought into proximity
and then set at an angle to the casing.
Figure 3, is a sectional plan of Figure 1, showing the pivotal centres with
their cable wheels.
Figure 4, is a sectional plan of Figure 1, above and below the opened sashes,
and,
Figure 5, is a side elevation of the upper and lower sashes showing their con-
nection with the cable pulleys by means of cables which are shown in broken
lines, and which are similar on both sides, this view shows more explicitly the
operation of the opening and closing device.
To more fully comprehend the operation of this adjustable and swinging sash, I
will indicate the upper window sash by 2, the lower one by 3, the window sash
casing by A, the inner vertical sides of said casing by 5, and the side stops of
the sash by 6.
The middle part of this casing has rigid pivots 8, projecting on each inner
side and in horizontal line, on which revolves the double grooved pulleys 9, by
means of cables 10, and 12, the ends of which are attached to the upper, and also
to the lower ends of the sashes, which when being adjusted, operates the cables
and pulleys.
These cables operate in conjunction with each other, all moving at the same
time, when adjusting the sashes, for instance, when the lower sash is lifted, the

page_text: upper sash must of necessity come down at the same time, the opening at the
top and the bottom being the same. To accomplish this adjustment of the sashes,
it will be observed, that in Figure 5, of the drawing, is seen the manner of
cable attachment to the sashes namely one end of the cable 10, is attached to the
upper end of the upper sash 2, then passes downwards, and half around the pul-
ley 9, then upwards the other end of said cable being attached to the upper end
of the lower sash 3. The cable 12, passes half way around the same pulley,
in the adjoining groove, and one end attached to the lower end of the upper
sash 2, and the other end attached to the lower end of the lower sash 3. These
pulleys and cables being similar at both sides of the casing, all operating together,
each of the four cables in its own pulley groove. It will be perceived that the
inner edges of the sashes have vertical recesses 16, formed therein, in order to
allow the sash to operate freely past the pulleys.
To swing the sashes, the upper and lower halves are brought into face
proximity, and then swung as seen in Figure 2, of the drawing, to accomplish
this, it is necessary to divide the inner casings 5, the side stops 6, and the inter-
mediate strips 7, at the segmental lines 18, and 18, to swing the sash, when in
vertical position, the inner casing 5, the side stops 6, and the intermediate
strips 7, which swing with the sash," are all in vertical line with the corre-
sponding inner casing, stops and strips of the rigid framework, above and below
the segmental lines 18, "Figures 1, and 2." The sashes can be moved one past
the other when in a swinging position.
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:-
1st. Window sashes comprising an outer casing, having inner pivots projecting
from the sides thereof and in horizontal line, double grooved pulleys to revolve
on said pivots, an upper and lower sash having inner recessed edges to pass and
allow freedom to said pulleys, chains, or cables, to operate on said pulleys, and
the ends to fasten to the ends of the sashes for supporting and balancing the
same, and side stops and intermediate guides for the sash, as described.
2nd.. Window sashes consisting of an outer casing, and an inner side casing,
pivotal centres projecting from the inner sides thereof, and in horizontal line,
grooved pulleys on said pivots, sashes in said casing having inner recessed side
edges to pass said pulleys, cables over said pulleys, with ends attached to the ends
of the sashes and vertical side stops and intermediate guides for the sash to
operate therein as described.
3rd. Adjustable and swinging window sashes, having vertically recessed side
edges for movement over grooved pulleys pivoted to the inner sides of an outer
frame or casing, an inner side casing between said pulleys and the sides of said
outer frame or casing, cables attached to the ends of said sashes, and over said
pulley to operate together and in conjunction therewith, side stops and inter-
mediate guide strips for the sashes, said sashes capable of swivel movement
together with its parts as specified and set forth, on said side pivots, the seg-
mental lines 18, and 18, being the divisional line of the central swivel, and the
upper and lower rigid parts, as described.
