Improvements in Window-sash Fasteners or Holders adapted to
Secure the Sash against Rattling and to Cause it to Exclude
Draughts.
I, JAMES HALL FOOTE, of 18 Moorman Avenue, Cincinnati, Hamilton County,
State of Ohio, United States of America, Manufacturer, 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 :-
The object of my invention is to provide a sash-fastener or holder of two parts,
one part to be attached to the bottom sill of a window-frame, the other part to be
attached to the bottom stile of the window-sash, said two parts being adapted to
engage each other and co-act to force said sash inward against the side-wall of the
vertical grooves in said frame when the sash is lowered, for the purposes hereinafter
set forth.
In the accompanying drawing:
Figure 1, is a front elevation of the lower portion of a window-frame and sash
provided with my improved fastener.
Figure 2, is an enlarged sectional view taken on dotted line 2, 2, of Fig. 1,
and
Figure 3, is a transverse section through one side of the frame and sash, on dotted
line 3, 3, of Fig. 1.
In the drawings, the window-frame is indicated by A, said frame being shown as
provided with the usual strips, a, a,-the space between the latter, at each side of
the frame, providing a groove within which the sides of the sash, B, engage, the
latter being capable of a vertical movement therein. C, represents a strip on the
bottom sill of the frame, against which the lower stile, b, of the sash is adapted to
engage. The construction thus far described is the same as that found in any
ordinary window,-my invention being applicable to any window having a movable
sash.
When constructed as shown, my invention consists of a plate, D, attached to the
lower stile, b, of the sash, and a plate, E, attached to the lower portion of the
window-frame, each of said plates having, respectively, the flanged portions d and e,
the former overlapping the latter when the sash is lowered, as more clearly shown
in Fig. 2. These flanges are preferably formed of a semi-conical configuration for
a greater portion of their length, excepting the free end portion of flange d and the
base of flange e, which portions are preferably made straight in vertical section, as
shown at f, in Fig. 2.
The operation of my improved window-sash fastener is quite simple and effective.
The flanged plates D and E are so attached to the frame and sash, that, when the
latter is lowered, the flange d will meet and slide down over the flange, e, which
action tends to draw the lower portion of the sash inward against the inner side
strips, a and the bottom strip C, thus rendering that portion of the window
comparatively air-tight to shut out dust, smoke, etc.; and at the same time prevents
all rattling of the sash during high winds. The straight vertical portions, f, of
the two flanges, act to securely hold the sash in its lowered position until released
by an upward pressure on the hand-holds, m, or other suitable portion of the
sash.
The advantages of my invention are apparent, operating as it does, to tightly
close the lower portion of a window, thus shutting out cold-air, dust, smoke, etc.,
and prevents rattling, which operation is accomplished automatically as the sash is
being lowered. The devices for accomplishing the aforesaid results, are cheap of

page_text: manufacture and are readily applied to any windows having a movable sash, and
their use dispenses with the necessity for weather-strips.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
(1.) A window-frame having a sash mounted therein in a movable position, in
combination with a plate attached to the bottom of said frame and another plate
attached to the bottom stile of the sash, said two plates having angular inclined
portions adapted to meet and impinge when said sash is lowered, for the purposes
specified.
(2.) A grooved window-frame having a sash movably mounted therein, plate E
having a flange e, and plate D having a flange d, said plates being attached to the
bottom sill of the frame, and the bottom stile of the sash, respectively, a portion of
each flange being formed straight in a vertical plane, substantially as set forth.
(3.) As a new article of manufacture, a sash-fastener consisting of two plates D
and É having, respectively, the flanges d and e, for the purposes specified.
Dated this 20th day of July 1894.
