We, MCCALL'S SLIDING HINGE-WINDOW COMPANY, of 215, Golden Gate Avenue,
in the City and County of San Francisco, State of California, U.S.A., a Corpora-
tion organized and existing under and by virtue of the laws of the State of
California, and WILLIAM MCCALL, President of the aforesaid Company, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in windows and is applicable to the
hinging of sashes to sliding strips upon which they are carried, which strips are
in turn connected with the cords of the counterbalance weights and are vertically
movable in the grooves or channels between the stops and parting beads. This
invention consists in a novel means for engaging the sash with the slidable strip
upon the side opposite to the hinge, so that it may be readily disengaged to
allow the sash to be opened inwardly, and in a means for holding the slidable
atrip after the sash has been disengaged therefrom to prevent the strip from
being carried up by the action of the counterweight. The invention also
comprises details of construction which will be more fully referred to in another
portion of this specification.
The window casing has the usual outside and inside stops and parting strips
between which the upper and lower sashes are slidable.
The parting strips may be rolled of sheet metal and made hollow in approxi-
mately a U-shaped section.
In order to allow these sushes to he opened inwardly so that both outer and
inner surfaces can be easily reached for cleaning or other purposes, the sashes
are hinged upon one side to vertically slidable strips.
These strips have a sufficient width in one direction to be equal to the thickness
of the window sashes and a sufficient thickness in the other direction so that
when in position between the parting strips and stops, they project toward the
Bash sufficiently to clear the stops, and when the sashes are hinged to these
strips they can be opened about their hinges without striking the stops.
The slidable strips to which the sashes are hinged at one edge, and against
which they close at the other side, are provided with plates, the edges of which
project and engage with the projecting edges of metal clasps which are fixed
to the window frame.
These clasps do not extend upwardly the full length and the plates may
consequently be disengaged from these clasps when the strips have been allowed
to move up near the top of the window. The strips can then be pulled out of
their guide channels for the purpose of repairing or renewing the cords.
The means for uniting the sash with the slidable strip consist of a bent angle
plate secured to the sliding strip with its surface flush with the inner side of
the strip, and a corresponding plate secured upon the edge of the sash.
These plates are both so set that a little channel equal in width to the thick-

page_text: ness of each of the plates, is left between the plates and the surfaces of the strip
and the sash, which abut when the sash is closed against the strip.
These plates are made of sufficient length to securely interlock when the sash
is closed against and coincident in length with the aforesaid vertically slidable
strip.
The lower end of the angle-plate has a lug turned outwardly which arrests
the edge of the plate secured upon the edge of the sash when it has been inter-
locked with it, and when the sash is thus interlocked with the strip and the
strip is not otherwise arrested, the counterweight pulling upon the strip will
maintain the sash and strip in engagement whether the sash be pushed up or
pulled down..
When it is desired to disengage the sash in order to open it about its hinges,
it is necessary to stop and hold the sliding strip at some suitable point.
This is effected by means of a hinge plate which is set transversely across the
face of the channel in which the strip slides, and it has a leaf which may be
normally turned down into the depression which is made for this plate, and
when thus turned down it is flush with the bottom of the channel and presents
no obstruction to the sliding of the strip.
When the leaf is turned up, it can only be turned to a position at right angles
with the other hinge flap or plate and is then arrested by stop lugs which abut
against the back of the latter plate when the leaf has been thus opened. These
lugs may be stamped out with the plate when it is formed.
In this position the leaf presents an obstruction against which the upper end
of the sliding strip will be arrested whenever the leaf is turned outwardly.
The leaf has a slot or channel cut away in its central portion to allow the
weight cord to move freely through it when the leaf is turned out to stop the
strip.
The operation will then be as follows:-
The sash having been drawn to the bottom, the leaf is turned so as to obstruct
the upward movement of the strip, and when the sash is raised the strip will
be stopped against the leaf and a further upward movement of the sash dis-
engages the locking plate from the angle-plate by passing above the edge thereof
when the sash can be freely opened about its hinges.
When again closed so that the locking plate is above the angle-plate the sash
is first pulled down until the plates are interlocked, and the sliding strip will
then be locked to the edge of the sash.
By pulling the two down a little way the leaf of the stop plate can be turned
down to its normal position and the sash is then slidable in the usual manner.

We, MCCALL'S SLIDING HINGE-WINDOW Co. of No. 215, Golden Gate Avenue,
in the City and County of San Francisco, State of California, U.S.A., a Corpora-
tion organized and existing under and by virtue of the laws of the State of
California, and WILLIAM MCCALL, President of the aforesaid Company, do hereby
declare the nature of this invention and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in windows and is applicable to the
hinging of sashes to sliding strips upon which they are carried, which strips are
in turn connected with the cords of the counterbalance weights and are vertically
movable in the grooves or channels between the stops and parting beads. This
invention consists in a novel means for engaging the sash with the slidable strip
upon the side opposite to the hinge, so that it may be readily disengaged to
allow the sash to be opened inwardly, and in a means for holding the slidable
strip after the sash has been disengaged therefrom to prevent the strip from
being carried up by the action of the counterweight. It also comprises details
of construction which will be more fully explained by reference to the accom-
panying drawings, in which-
Figure 1 is an inside view of the window. Figure 2 is a horizontal section
through the centre of the lower sash. Figure 3 is a face view of the right hand
slide. Figure 4 is a vertical section through the slide stopping device. Figure 5
is a view of the stop plate.
A is a window casing having the usual outside and inside stops and parting
strips between which the upper and lower sashes B and B are slidable.
The parting strips may be rolled of sheet metal and made hollow as shown
in section at R.
In order to allow these sashes to be opened inwardly so that both outer and
inner surfaces can be easily reached for cleaning or other purposes, the sashes
are hinged upon one side to vertically slidable strips C.
These strips have a sufficient width in one direction to be equal to the thickness
of the window sashes and a sufficient thickness in the other direction so that
when in position between the parting strips and stops, they project toward the
sash sufficiently to clear the stops, and when the sashes are hinged to those
strips they can be opened about their hinges without striking the stops.
The slidable strips C to which the sashes are hinged at one edge, and against
which they close at the other side, are provided with plates D, the edges of
which project and engage with the projecting edges of metal clasps E which are
fixed to the window frame.
The clasps E do not extend the full length of the frame and the plates D may
consequently be disengaged from these clasps when the strips have been allowed
to move towards either the top or bottom of the window. The strips can then
he pulled out of their guide channels for the purpose of repairing or renewing
the cords.
The means for uniting the sash with the slidable strip consists of an angle
plate G bent as shown and secured to the sliding strip O with its surface flush
with the inner side of the strip, and a corresponding plate H secured upon the
edge of the sash.
These plates are both so set that a little channel equal in width to the thick-
ness of each of the plates, is left between the plates and the surfaces of the strip
and the sash, which abut when the sash is closed against the strip.
These plates are made of sufficient length to securely interlock when the sash
is closed against and coincident in length with the strip C.
The lower end of the plate has a lug g turned outwardly which arrests the
edge of the plate II when the latter has been interlocked with it, and when the
sash is thus interlocked with the strip and the strip is not otherwise arrested,
the counterweight pulling upon the strip will maintain the sash and strip in
engagement whether the sash be pushed up or pulled down.
When it is desired to disengage the sash in order to open it about its hinges,
it is necessary to stop and hold the sliding strip C at some suitable point.
This is effected by means of a hinge plate I which is set transversely across
the face of the channel in which the strip C slides, and it has a leaf I' which may

page_text: be normally turned down into the depression which is made for this plate, and
when thus turned down it is flush with the bottom of the channel and presents
no obstruction to the sliding of the strip C.
When the leaf I is turned up, it can only be turned to a position at right
angles with the part I and is then arrested by stop lugs i which abut against
the back of the plate I when the leaf has been thus opened. These lugs may
be stamped out with the plate when it is formed.
In this position the leaf presents an obstruction against which the upper end
of the sliding strip C will be arrested whenever the leaf is turned outwardly.
The leaf has a slot or channel J cut away in its central portion to allow the
weight cord to move freely through it when the leaf is turned out to stop the
strip C.
The operation will then be as follows:
The sash having been drawn to the bottom, the leaf is turned so as to obstruct
the upward movement of the strip C, and when the sash is raised the strip C
will be stopped against the leaf and a further upward movement of the sash
disengages the locking plate H from the plate G by passing above the edge thereof
when the sash can be freely opened about its hinges.
When again closed so that the plate H is above the plate G, the sash is first
pulled down until the plates are interlocked, and the strip C will then be locked
to the edge of the sash.
By pulling the two down a little way the leaf I' of the stop plate can be
turned down to its normal position and the sash is then slidable in the usual
manner.
Having now particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, it is declared that
what is claimed is:-
1st. In a hinged and slidable window of the character described, slidable
strips to one edge of each of which one of the sashes is hinged, and guides by
which the strips are retained in their channels, corresponding strips upon their
opposite sides against which the free edges of the sashes close and vertical inter-
locking plates by which the said edges of the sashes are connected with the
slidable strips, hinged plates fixed in the channels in which the strips slide, said
plates having outwardly turnable leaves with lugs whereby the leaves are arrested
at right angles with the main plates so as to form a stop against which the upper
ends of the strips are arrested and having central slots through which the
counterweight cord is movable.
2nd. In a hinged and slidable window, sashes hinged to strips vertically
slidable in guides in one side of the frame, other strips slidable in the opposite
side of the frame, guides by which the strips are engaged and retained when
in the normal or closed position, and from which they disengage at the other
part of their travel, vertical interlocking plates upon the free edges of the sashes
and the corresponding sliding strips, and foldable stops by which said strips
may be arrested and the sashes raised and disengaged therefrom.
