An Improvement in Window Glass Setting.
I, JOHN VALENTINE AUTH a Glass Worker residing at Kerr Avenue in the City
of Pittsburg, county of Allegheny and State of Pennsylvania, United States of
America do hereby declare the nature of my invention for AN IMPROVEMENT IN
WINDOW GLASS SETTING, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:―
In the accompanying drawings,
Fig. 1. is a longitudinal sectional view of a sash with my improvement applied.
Fig. 2. is a perspective view of a piece of glass, showing my rubber cushion
attached.
Fig. 3. is an enlarged perspective view of a portion of my improved cushion.
Before describing the details of construction I wish to say that I am well aware
that it is not new to place a cushion in the rabbet of a sash, which rabbet is closed by
a secureing strip placed against the outer side of the glass.
The object of the present invention is to provide a cheap and simple means for
permitting the expansion and contraction of glass or lights such as used in windows
of houses, the same also serving as a cushion and a means of security in setting and
handling the glass while placing it in the sash. The novelty consists in the
construction and adaptation of parts, as will presently be set forth, and pointed out
in the claim.
Referring by letters to the drawings, A. indicates a sash, which may be of any
ordinary or approved construction, having a groove or rabbet to recieve the
glass.
B, indicates a glass which I have shown as being rectangular in outline, although it
be of other form.
may
Č, indicates the cushion which I apply to the edge of the glass and in the groove
or rabbet of the sash. This cushion I have shown as being composed of rubber,
moulded in the form of the letter U. This cushion after being cut into proper
length is stretched over the edges of the glass as more fully shown in Fig. 2. It
should be observed that this cushion being formed from rubber, may be obtained at
a very small expense and that its resiliency will cause it to adhere to the glass, before

I attach importance to this cushion, and to the fact that it may be so quickly applied
around the edges of the glass that it may adhere thereto and protect the hands of the
workman. It is obvious that this cushion may be of any suitable weight according
to the size of the glass and the sash in which it is to be used. It is also obvious that
if a glass should become broken or injured the tubing may be removed and placed
upon another.
In operation, when the rubber has been placed over the edges of the glass, the
whole may be secured in position by means of the strip b, and screws or other suitable
fastening devices. Should the plate of glass thus set up or placed in a window-framo
expand when subjected to very high temperature, the rubber will yield, and thereby
provent serious damage to the glass; or should the building settle or the frame warp,
the glass will be protected from breakage.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is-
The combination of the window-sash, the rubber cushion c, applied to the edges of the
glass, and the strips 6, confining the rubber and glass in the groove of the sash,
substantially as specified.
