Improvements in Window Fasteners
I, GEORGE HERBERT YOST, of 309 West 54th Stiect, in the City, County and
State of New York, United States of America, Inventor, do hereby declare the
nature of this invention to be as follows
-
This invention clates to supports and lorks for window sashes, and the object
thereof is to provide an effective device of this class, which is simple in construction
and operation and also comparatively inexpensive
The invention is fully disclosed in the following Specification, of which the
accompanying drawing, forms a part in which
Fig. 1, is a view of a window frame, and the sash mounted therein showing my
improved lock or support in section.
Fig 2, a similar view of an enlarged scale,
Fig 3, a front or side view of a modified form of construction which is, also
shown in Fig. 2, on a smaller scale and,
Fig 4, a section on the line 4-4, of Fig. 3.
In the accompanying diawing, A, represents an ordinary window frame, and B,
and C, the upper and lower sashes respectively
Formed in one side of the sash B, is a chamber of leress D, the walls of which
are inclined upwardly, and downwardly, as clearly shown in Fig. 2, said chamber
01 recess being comical in form in longitudinal section and the apex thereof being
directed inwardly and formed in the sash is a transverse opening E, which
communicates with the chamber D
Placed with the chamber D, and secured to the upper and lower walls thereof is
a plate spring F, in the centre of which is formed an opening G, and between the
plate spring F and the frame A, of the window is placed a ball oi spherical body H
which is preferably composed of rubber and the surface of which 13 also proferably
roughened.
Connected with the ball H, is a cord K, which extends through the opening G,
in the sping F, and through the opening or passage E, in the frame and depends
therefiom as clearly shown in Figs. 1 and 2
The operation will be readily understood from the foregoing description when
taken in connection with the accompanying diawing The normal operation of the
spring F, is to press the ball II, outwaid and the force of this spring is sufficient at
all times to hold the window sash in any desired position in the following manner.
If it is desired to lower the sash the ball H, will roll up along the inclined surface
formed by the spring F, in the upper wall of the chamber D, and be securely
wedged between the frame and the sash and if it is desired to raise the sash this
operation of the ball will be repeated on the lower inclined surface formed by the
spring F, and the lower wall of the chamber D. It therefore results that when it
is desired to raise or lower the sash to any position it is necessary to pull upon the
cord K, with force sufficient to overcome the action of the spring F, when the
window sash may be raised or lowered as will be readily understood.
In Figs 3, and 4, and at the lower right hand corner of Fig. 1, I have shown a
In this form of
modified form of my improved window support and lock
construction employ the chauber D, which is of substantially the same form as
shown in Figs. 1, and 2, but in place of the spring F, and the cord K, I substitute
a rod L, which is connected with the ball H, and extends through the side of tue
Bash, the chamber D, being formed in said sash as herein before described, and the

page_text: side of the sash bemg provided with a plate L, in which is formed a segmental
slot M, though which the od L, passes, and the operation of this form of
construction will be substantially the same as that herein before described The
ball H, may be operated by means of the rod I, so as to raise and lower the
window sash, and said ball will operate to hold the sash in any desired position
when raised.
My invention is not limited to the exact form, construction, and arrangement of
parts shown and described; and I therefore reserve the right to wake all such
alterations therein and modifications thereof, as fairly come within the scope of the
invention
Having fully described my invention, I claim and desire to secure by Letters
Patent-
1 The combination with a sash of a window of a support or lock, comprising a
chamber which is formed in the outer side of the sash in which is placed a ball
8 II, the upper and lower walls of said chamber being inclined, so as to form
mclined planes over which said ball moves and by means of which said ball 18
adapted to secure the sash in position, substantially as shown and described
2. In a window sash support, the combination of a window sash provided with a
chamber formed in the outer surface of one of the side frames thereof, the upper
and lower walls of said chamber being inclined, a ball placed in said chamber and
adapted to operate in connection with the walls thereof, and the frame of the
window and means connected with said ball for presenting the action thereof
while the window sash is raised or lowered, substantially as shown and described.
3. The combination with the sash of a window, having a chamber formed in one
Bide thereof, the upper and lower walls of which are inclined, a spring located in
said chamber, a ball as H, placed between said spring and the frame of the window
and a cord or similar device connected with said ball and extending through the
opening in the sash, substantially as shown and described
