page_text: In connecting these chains or cords with the stiles or bars K, we form in the
outer sides of the upper ends thereof, vertical slots or grooves M, as shown in
Figs. 7 and 8, and at the lower ends of these slots or grooves M, we set into the
stiles or bars a. circular plate m, the upper side of which is cut away so as to form
an angular notch or recess m³, and said circular plate m, is provided on its lower
edge with an inwardly directed segmental flange m 2, and at each side of the
angular notch or recess m', are inwardly directed lugs or shoulders m 3, and the
chains or cords L, are secured in any suitable manner to the block m 4, which
is passed behind these shoulders or projections m 3, as shown in Figs. 7 and 8.
Each of the stiles or bars K, is provided on its outer side and near its upper
and lower ends with spring operated plates N, set into oblong slots or recesses n
formed in the sides of the stiles or bars. The outer surface of these plates N,
is bevelled at the upper ends thereof as shown at n', and the inner surface
thereof is bevelled at the lower end as shown at n2, and the lower ends of
I said plates are secured to the stiles or bars by a screw n 3, or in any preferred
manner.
Secured to the inner side of the free or upper end of the plates M, is an
inwardly directed cylinder n 4, which passes through the stile or bar, and formed
around the same is an annular chamber in which is mounted a spiral spring n 5,
the object of which is to force the plate N, outward against the sides A, of the
window frame, and thus force the stiles or bars inwardly.
The sash frames are pivotally connected with stiles or bars K, at the center
thereof, as shown at O, in Figs. 1 and 2, and this pivotal connection is made in
the following manner. The vertical sides of the sash frame are provided on their
outer surfaces with longitudinal grooves P, which may be of any desired shape in
cross-section, and the adjacent surfaces of the stiles or bars K, are provided with
corresponding longitudinal beads or bevelled portions P, which are adapted to fit
therein and sunk into the sides of the sashes in the bottom of the longitudinal
grooves P, are plates R, which are provided centrally with outwardly directed
cylindrical extensions R, which extend partway through the stiles or bara K, as
shown in Figs. 4 and 5, and said stiles or bars K, are provided at this point, on
their outer surfaces, with cavities or recesses k.
Passing through the cylindrical extension R', of the plate R, is a pivot pin S,
through the inner end of which is passed a pin S', which rests in a chamber
beneath the plate R, and mounted on the outer end of said pivot pin S within
the cavity or recess K, is a plate k¹, which is held in place by a pin k 2, and
between the plate k¹, and the end of the cylindrical extension R¹ of the plate R,
is a spiral spring T. The spring T and pin S hold the vertical side of the sash
frame against the adjacent surface of the bar K when the window is closed but
allow of the bar K being pushed back far enough for the projecting rib P³ to clear
the sides of the groove P, when the sash is turned on its pivots.
It will be understood that the sashes are thus free to revolve about the
extensions R, and between the stiles or bars K, and that said stiles or hars project
beyond the beads or strips D, E, and F, and when the sashes are closed or in
the normal position, the said stiles or bars, forced inwardly so that the
longitudinal rib or convex portion P', enters the longitudinal groove or concave
portion P of the sashes, and thus forms a close fit and air-tight connection
between said sashes and the stiles or bars. The longitudinal grooves P, or
. concave portions of the sides of the sashes may be of any desired form in cross-
section, and the corresponding longitudinal convex portion of the stiles or bars
must be adapted to fit therein, and when the sashes are closed as herein before
stated, these parts are forced together by the action of the springs n5, on the
plates N, as hereinbefore described, and when the sashes are tilted on their
pivotal connection as shown in Figs. 2 and 3, the stiles or bars are forced
outwardly by reason of the formation of the joint between said stiles and bars,"
said joint comprising the longitudinal grooves P, or concave portions of the
sashes, and the longitudinal bead or concave portion P¹ of the stiles or bars.

page_text: Whenever it is desired to open or revolve one of the sashes, it is only
necessary to catch hold of either the lower or upper ent thereof and to pull
inwardly or shove outwardly thereon, as will be readily understood, and this
operation will result in turning the sash on its pivotal supports, as shown in
Figs. 2 and 3, and in this operation the stiles or bars K, are forced outwardly, so
as to fill, or nearly fill the space between the same and the sides of the window:
frame, and by reversing this operation the sash may be turned to the closed
position in which the stiles or bars K, will be forced inwardly by the springs a 5,
as hereinbefore described.
It will be understood, of course, that either of the sashes, the upper or the lower
one, may be turned or revolved independently of the other, or that both of said.
sashes may be turned together, and it will be also understood that when it is
desired to revolve the lower sash it must be raised so that the lower side thereof
will be free from the strip or bead at the bottom of the frame, and when it is
desired to revolve the upper sash, the same must be lowered so that it will be free
from the strip or bead at the top of the frame.
From the foregoing description it will be seen, that the window sashes are
supported entirely and solely by the vertically movable stiles or bars K, and that
the stiles or bars are provided with the usual counter-balanced weights and cords,
and our invention is not limited to the exact form, construction and arrangements
of parts herein shown and described; and we therefore reserve the right to
make all such alterations therein, and modification thereof, as fairly come within
the scope of the invention.
In the construction berein shown and described, we also employ loops or
staples U, which are set into the side of the sashes H, and in the bottoms of the
concave portions or grooves P, and the object' of these staples or loops is to
provide a bearing surface against which the ends of the cylinders n 4, strike as shown
in Figs. 1 and 6, and which serve to press the plates N, outwardly and to prevent
the shaking or rattling of the sashes when the latter are closed.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
