Improvements in Means for Preventing Window-sashes from
Rattling.
I, GEORGE KENDALL, of Baltimore, in the County of Baltimore and State of
Maryland, United States of America, Inventor 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:-
This invention relates to a device to prevent window-sashes from rattling; and it
consists of a turn-button of special shape attached to a vertical strip and pressing
against the sash as hereinafter described.
The invention is illustrated in the accompanying drawings, in which-
Figure 1 is a front view of a window frame and sash with the improved turn-button.
Fig. 2 is a vertical section of the same.
Fig. 3 is a side view of the turn button in the position it has when holding the sash.
Fig. 4 is a view of the same parts with the turn button in the released position.
Fig. 5 is a view of the turn-button alone.
The letter A designates the sash, B the outside weather-strip and parting-strip, and
C the leading or inside sash-strip. In this ordinary construction for window-sash the
sash must be free to move up and down easily, and this necessary looseness or freedom
gives rise to rattling of the sash, which it is the object of this invention to prevent.
Turn-button d, of peculiar shape, is employed to press the sash outward against the
weather strip B. The turn-button has a triangular shape, the two sides ef being at
right angles with respect to each other. At the apex or joinder of these two sides is
a curve g, which is the segment of a circle. The center of this curve is denoted by a
small cross h. The pivot hole i is eccentric with respect to the curve g, and a screw i¹
through the pivot-hole into the beading-strip C holds the turn-button.
The action of the turn-button is as follows:
The pressure against the sash is effected by that side of the eccentric curve which
adjoins the angle side e, as in Fig. 3. This part e in this operation should point
upward. The straight side e comes against the sash and prevents the button from
turning any farther.
The angle side ƒ projects outward and serves as a handle. When turned to the
release position, as in Fig. 4, the part f points downward and bears loosely against
the sash and merely prevents the button from turning over.
In this position of the device the sash is free to be raised or lowered. The turn-
button will release its pressure on the sash automatically when the sash is lifted. This
turn-button may be made of wood, inetal, hard rubber, or other material.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :
In an anti-sash-rattler, the combination of the sash, the inside vertical sash-strip C,
and a triangular-shaped turn-button having a curve o at the apex or joinder of its two

page_text: right-angled sides ef and provided with a pivot i', eccentric with respect to said curve,
whereby that part of the eccentric curve adjoining the upper right-angled side e will
serve to press the sash, while the straight part of the said side prevents the turn-
button from turning any farther, substantially as described.
