Improvements in Windows.
I, FERDINAND CHRISTOPH VON HEYDEBRAND UND DER LASA, Artist,
residing at No. 1959 Madison Avenue New York City in the United States of
America do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described in and by the following
statement:-
My invention relates to windows, and has for its object to provide a construction
wherein the sashes both slide and swing, which action greatly facilitates the
cleaning of the window.
To this end my invention consists in the construction which enables me to reverse
the sash in the casing to bring the outside face of the window inside of the room
or building, so that the outside of the sash and window may be cleaned without
rendering it necessary for the cleaner to go outside of the building.
My invention further consists in details of construction hereinafter set forth,
illustrated in the accompanying drawings and more particularly pointed out in the
claims.
I am aware that it has been hitherto proposed to provide windows with sliding
and swinging sashes, but by my improvement 1 am enabled to make a practical
structure of the more or less imperfect and impractical structures hitherto
proposed.
I attain the objects of my said invention by the construction shown in the
accompanying drawing wherein―
Figure 1 is a perspective view of one side of my improved window showing the
sash in its normal position;
Figure 2 is a similar view, parts being broken away and removed in order to
clearly show the method of pivoting the sliding sash:
Figure 3 is a horizontal section of Figure 4;
Figure 4 is a detail view of the movable bearings or pivot hooks upon which the
sash pivots rest, as will be more fully hereinafter set forth;
Figure 5 is an isometric view similar to Figure 1 showing the window sash in a
tilted position;
Figure 6 is a detail view of an end of one of the removable sections of the beads
showing a method of fastening the same in place;
Figure 7 is a detail view of the other end of a bead, as shown in Figure 6; and
Figure 8 is a socket-plate for the reception of the dowels of the removable bead,
all of which will more fully hereinafter appear.
In the drawings, A. represents a portion of the window casing having therein
vertical grooves a for the reception of the sash pivots. These grooves I preferably
provide with edge-plates b. B B are sliding window sashes provided with pivots c
which enter the grooves in the window casing. These sashes are suspended by any
suitable form of sash-cord, in the present case shown as a chain d, which sash-cord
is secured to or otherwise engages the sash pivots c, thus holding the window sash
suspended. The window casing is provided with the usual inside and outside
beads, of which the section f is made removable, although the entire bead may be
removed, if desired. I may secure this removable section f in place in any
suitable manner, as by means of a socket-plate g in the sill C, the removable section
being provided with dowel-pins h h for entering the apertures i in the socket-plate
and at its other end with a spring-catch k whose bolt enters an aperture in the
fixed or stationary section of the bead.

page_text: Within suitable recesses m in the window casing I provide movable bearings or
hooks n which are shown in this case as pivoted to the casing, but it will be obvious
that the bearings may take other forms and may be otherwise mounted without
departing from the spirit of my invention, nor is it necessary that these bearings
should be sunk in the casing as they may be otherwise disposed.
I have shown these hooks as provided each with a notch o for the reception of a
sash pivot when the hook is in position for use and with a barb p to engage over
the ping in the casing. In the normal operation of the window the hooks are
swung back in their recesses and the vertical slots offer a free and unobstructed
way for the passage of the sash pivots when the sash is raised or lowered.
normal operation, which is in all respects similar to the operation of the ordinary
window, the removable beads are in place, as shown in Figure 1, the sashes being
counterbalanced in the usual manner to admit of readily sliding them up and
down.
In this
Now, when it is desired to reverse either sash for cleaning, the lower sash
is raised, the removable sections of the beads removed, the movable bearings
brought into position in the slot a, the sashes can then be slid down one at a time,
and the sash pivot will rest upon the bearing which forms a rigid support therefor,
and the sash can thereupon be rotated upon its pivots, as shown in Figure 5, and
the sash reversed on its pivots when the outside of the sash can readily be cleaned
from within the building. While I have shown a specific structure and have
described the same in positive terms, I would have it understood that I do not
thereby expressly limit myself to this structure, as the details may be varied without
departing from the spirit of my invention which is essentially to provide some
means for rigidly supporting the sash upon trunnions in order to revolve the same
and as a corollary thereto to provide some means for moving the beads which guide
the sash which may be done either by removing the entire bead or a section of the
bead, or by hinging the bead or a section thereof, if desired. The other details are
likewise capable of many variations.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I would observe that
I do not claim broadly a sliding and swinging window suspended upon sash-cords
by sash pivots and adapted to be reversed to be cleaned, as I am aware that such a
construction is shown in the United States Patent of Francis Greene and Mary A.
Greene for Window, No. 458,392, dated August 25th, 1891, but what I claim is:
1. In a window, the combination of a casing provided with vertical grooves, a
window sash provided with pivots entering the said grooves in the casing, and
bearings in the grooves normally out of engagement with the sash pivots, but with
which they are engaged to temporarily suspend the sash so that the same may be
swung upon its pivots, substantially as described.
2. In a window, the combination of a casing, vertical grooves therein, a vertically
moving sash provided with pivots entering the said grooves in the casing, and
movable bearings normally disconnected from the sash-pivots but adapted to be
moved into the path of the sash-pivots to co-operate therewith, to temporarily
suspend the sash so that the same may swing on its pivots, substantially as
described.
3. In a window, the combination of a casing having grooves therein, a sash
provided with pivots entering and traversing the grooves in the casing and pivoted
hooks adapted to be swung into the path of the sash-pivots to co-operate therewith
to suspend the sash to swing upon its pivots, substantially as described.
4. In a window, the combination of a casing provided with vertical grooves, a
sash provided with pivots entering and traversing the grooves, bearing within the
grooves normally out of engagement with the sash-pivots but adapted to be
engaged therewith, to temporarily hold the window suspended, in order that the
same may be turned on its pivots, and movable inside and outside beads,
substantially as described.

page_text: 5. In a window, the combination of a casing provided with vertical grooves, a
sash provided with pivots entering the grooves, pivoted hooks adapted to be
swung across the grooves to co-operate with the sash pivots to hold the sash
suspended, and movable inside and outside beads, substantially as described.
6. In a window, the combination of a sash provided with pivots, a casing
provided with vertical grooves and with recesses in proximity to said grooves,
together with pivoted hooks located in the recesses and adapted to be swung
across the grooves to co-operate with the sash-pivots, substantially as described.
7. The combination in a window, of a sash provided with pivots, a casing
provided with vertical grooves and recesses in proximity to said grooves, pivoted
hooks located within the recesses and adapted to be swung across the grooves to
co-operate with the sash-pivots, and stop-pins for limiting the movement of the
hooks, substantially as described.
