WINDOW SASHES."
"IMPROVEMENTS IN
The Invention has for its object to prevent the influx of air through the windows,
and consists in providing the window casings with strips or bars, preferably of
wood, which fit into corresponding grooves or recesses of the sash bars, and are
faced with felt or other suitable material for making a tight fit. I prefer to use
three bars on each side of the window, the central one being the usual or enlarged
guide post between the sashes extending from the top to the bottom of the window
and forming a guide, and fit for the inner side of the sash frames, while the two
other strips or bars are shorter, one of them extending from the top to about the
centre of the window, so as to make a tight fit for the outside of the upper sash,
and the other extending from the bottom to about the centre, so as to form a tight
fit for the lower sash. The outer bars may be concealed from view by covering
them partly with mouldings. To make the joint complete the ledges or mouldings
at the sill and at the top of the window, as well as the two cross bars of the upper
and lower sash, which come into contact with each other when the window is shut,
may also be faced with felt or other suitable compressible material.

WINDOW SASHES."
"IMPROVEMENTS IN
The Invention has for its object to prevent the influx of air through closed
windows, and consists in providing the window casings with strips or bars,
preferably of wood, which fit into corresponding grooves or recesses of the sash
bars, and may or may not be faced with felt or other suitable material for making
a tight fit. I prefer to use two tapered bars or battens on each side of the window,
one for the upper sash reaching from the top to about the middle of the window, and
one for the lower sash reaching from the middle to the bottom of the window.
The said battens may either be rigidly attached to the window casing (for instance,
by securing them to the beads) or the battens may be placed upon springs which
become compressed on the window being shut. To make the joint complete the
sill and top of the window, as well as the two cross bars of the upper and lower
sash, which come into contact with each other, may also be faced with felt or other
suitable packing. My Invention, which can either be embodied in the construction
of new windows or applied to existing windows, will be more clearly understood
by reference to the annexed Drawings, in which Fig. 1 represents a front elevation
of a window; Fig. 2, a cross section of sill with inner side elevation of window
casing to the height of one sash, showing also a batten A with spring adjuster ;
Fig. 3, a cross section of sill with batten A screwed to bead; Fig. 4, a horizontal
section of one side of the window casing, batten, and sash; Fig. 5, a detail view of
the batten A; and Fig. 6, a side elevation of the lower sash and batten. A (as
already mentioned) is the batten, which may or may not be lined with felt a
(Fig. 6); B, B, the sashes; D, D, the window casing; &, spring adjuster. The felt
lining, if used, may be attached to the batten or to the groove.
In witness whereof, I, the said George Hartig, have hereunto set my hand
and seal, this Thirteenth day of October, A.D. 1879.
