Improvements in Reversible Windows.
We, LOUIS PROLL, Music Teacher, of No. 1319, Larkin Street, CHARLES MILTON
DEPEW, Contractor, of No. 308, San Jose Avenue, EUGENE WATSON HAWLEY,
Book-keeper, of No. 2840, Mission Street, and GERTRUDE PROLL, Music Teacher,
ef No. 1319, Larkin Street, all in the City and County of San Francisco, State of
California, U.S.A., 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:-
Our invention relates to an attachment for windows by which we are enabled
to turn or reverse the sashes about pivots centrally disposed in opposite sides, so
that the windows may be turned at right angles with the line in which they
ordinarily slide. It consists in certain details of construction which will be more
fully explained by reference to the accompanying drawings, in which,
Figure 1 is a general view of the window. Figure 2 is a vertical section
through one side of casing and sash on line 2-z of Fig. 4. Figure 3 is a
top view of the lower sash showing the locking device. Figure 4 is a horizontal
section on line x-x of Fig. 2. Figure 5 is a similar section on line yy of
Fig. 2. Figures 6 and 7 show the chain suspending device.
In the construction of our device, the sashes A which are slidable with relation
to the casing B of the window are made of such a width from side to side as to
allow them to turn between the parting strips of the casings B and to slide in a
chase or groove formed by b and B, see Figure 4. C is a groove or channel by
which the sashes A are guided, and D are slides of a width equal to the thickness
of the sash having a length corresponding with that of the sash and adapted to
slide in the grooves or channels C.
To these slides the sashes A are pivoted at about the centre, by pivot pins E,
and as the sashes are no wider than the distance between the parting strips, (the
slides D filling the depths of the channels C) it will be understood that the
sashes may, when free, be turned about their pivot pins E so as to stand at any
desired angle, or be reversed to expose the outer surfaces to the interior.
In order to lock the sashes A to the sliding pieces D, we have shewn the slides
formed with channels F extending vertically and corresponding channels are made
in the sashes.
Within these channels in the sashes are fitted strips G preferably of metal and
of a thickness which will allow them to be moved into the slots F in the slides D,
so that when in this position the sashes and the slides D will be locked together
and will then be slidable up and down in the channels in the casing in the
manner of any ordinary window.
When the strips G are moved into the sash so as to be disengaged from the
sliding pieces D, the sashes will then be free to turn about their pivot pins E as
previously described.
These strips G have inclined slots H made in them and these slots fit over
pins I which are fixed in the sashes so that when the strips G are moved upwardly,
they will slide at the same time inwardly by reason of the inclination of the
slots H, until they lie entirely within the sashes to allow the latter to be turned
when thus released.

page_text: When the strips G are again moved outwardly and downwardly, the outer
edges of the strips G enter slots in the sliding pieces D and thus lock the
sashes to them.
In order to conveniently disengage the strips G from the slides D, we have
shewn short lever arms J fulcrumed or pivoted to the sashes, as shewn at K, so
that the outer ends project within reach of the, operator while the inner ends
engage grooves or channels I in the strips G. It will be seen by this construction
that the strips G will normally slide downwardly and outwardly upon the pins I
by reason of the diagonal position of the slots H, and the outer edges of the strips
will engage the channels F in the sliding pieces D) and thus hold the sash and
slides together. When it is desired to turn the window it is only necessary to
press upon the two thumb pieces J upon opposite sides of the sash when the
strips G will be raised, and by reason of the inclined slots drawn into the sash at
the same time, so as to leave the latter free to turn about its pivot pins E.
Jare projections fixed just below the lever arms J, which enable the operator
to grasp both between the thumb and fingers, and thus exercise the necessary
pressure to operate the levers J and disengage the strips G.
When the sash is restored to its normal position, the strips G will naturally
drop into the slots in the slides D.
The sliding pieces D to which the sashes are pivoted may be connected with the
counterbalance weights by means of a cord or chain (.
When the cord is used an eye or loop may be formed at the end opposite to
that to which the weight is attached, and this loop is slipped over a cylindrical
projection P which has a flange P1 upon the outside, this flange and the cylindrical
portion being countersunk into the slide D and secured by screws or otherwise.
The pivot pins E form extensions from the centre of the part P and their inner
ends project into socket pieces on which the sashes turn, as previously described.
In some cases chains are used in place of the cords in which case an extension P
is made from the upper part of the cylindrical portion P having a transverse
channel made in it as shewn at R.
This channel is of such shape that the cylindrical end of the link may be
slipped into it, the shank passing upwardly through a narrower portion of the
channel which extends to the top of the extension P2. A. pin S is then placed
behind the head of the chain link and this prevents its being withdrawn.
A rope or chain extends upwardly in a groove or channel formed in the slide 1)
and passing over the usual direction pulleys connects with the weight at the
epposite end. In order to lock the upper and lower sashes when the windows are
closed, we have shown a lever arm T fulcrumed upon the top of the lower sash
as shewn at U.
This lever arm carries a pin or equivalent locking device T1 at the end which
is adapted to engage a hole or locking device in the other sash. This lever is
normally acted upon by a spring V which when the lever is free and the pin T"
in line with the hole or engaging device in the other sash, will cause it to engage
and thus lock the sashes together.
In order to disengage this lever when it is desired to move the sashes, an in-
clined projection W is formed upon the upper end of the sliding strip G so that
when these strips are moved to draw them into the sash and disengage them from
the sliding pieces D), this incline will act upon the end of the lever T which is
adjacent to the sliding strip G and will thus press that end of the lever against
the tension of the spring V, and correspondingly moving the opposite end will
disengage the locking point T from the other sash, thus allowing the sashes to be
moved independently of each other.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
(1). In a window, vertically slidable sashes, pieces fitting channels between the

page_text: parting strips in the window casing, pivot pins by which the sashes are connected
with the slides and turnable about the pins, grooves or channels made in the
slides and the edges of the sashes in line with each other vertically, slidable strips
fitting said grooves or channels having diagonal slots movable upon fixed pins
at the upper and lower ends whereby the upward and diagonal movement of said
strips upon the pins depresses them into the sash slots and disengages them from
the slides and the downward movement correspondingly projects them from the
sashes and causes them to engage and connect both the sashes and slides, and levers
fulcrumed to the sashes, each one having one end to engage one of the strips, and
the opposite end projecting through the inner edge of the sash for raising said
strip to disengage.
(2). In a window, vertically slidable sashes, independent pieces slidable in
guides or channels in the window casings and pivot pins by which the sashes are
turnable connected therewith, grooves or channels made in the slides and in the
sashes, slidable strips fitting said grooves or channels having diagonal slots at the
top and bottom, and stationary pins extending into the slots whereby the upward
movement of the strips disengages them from the sliding pieces to which the sashes
are pivoted and the downward movement causes them to be projected and engaged
therewith, levers engaging said strips projecting through the inner edges of the
sashes and corresponding projections fixed to the sashes with relation to the lever M
so that the two may be grasped simultaneously to form a purchase to operate the
levers.
(3). In a window, vertically sliding sashes, corresponding slides fitting grooves
or channels in the casing and slots made in the slides and the edges of the sashes
with strips movable to engage the two or disengage them, pivot pins connecting
the sashes with the slides whereby the sashes are turnable about said pins, and
extensions of the pins outwardly whereby they are fixed to the slides, said ex-
tensions forming attachments for the counter-weight cords or chains.
(4). In a window, vertically slidable sashes detachably engaged with slides which
are adapted to travel in grooves or channels formed in the window casing, pivot
pins fixed to the slides and extending into sockets in the sashes whereby the
latter are turnable upon said pins when the locking devices between the sash and
the slides are disengaged, extensions from the pivot pins having sockets adapted
to receive enlarged heads upon the chain or cord whereby the latter is connected
with the pivot pins and slides.
(5). In a window, vertically slidable sashes, slides fitting in grooves or channels
in the casing, pivot pins uniting the slides with the sashes whereby the sashes
may be turned horizontally about said pivot pins, strips fitting channels made in
line with each other in the slides and the sashes, inclined slots made in the strips
and slidable upon fixed pins with means whereby the strips may be raised and
sunk into the channels in the sashes so as to disengage them from the slides, or
allowed to drop and be projected from the sashes and engaged with the slides,
locking levers fulcrumed to the top of the lower sashes having projections adapted
to engage with the lower rail of the upper sash, and inclined lugs upon the lock-
ing strips adapted to engage the lever and turn it to unlock the sashes when the
strips are raised to disengage the sashes from the slides and a spring whereby the
lever is actuated to again lock the sashes when the strips are allowed to drop and
