Year: 1881

page_text: LETTERS PATENT to William Clark, of 53, Chancery Lane, in the County of
Middlesex, Patent Agent, for an Invention of "IMPROVED MEANS OF
FIXING OR SECURING WINDOW GLASS." A communication from abroad by
Theopilus Tanner, of Osage, in the County of Otoe, State of Nebraska, United
States of America.
PROVISIONAL SPECIFICATION left by the said William Clark at the Office
of the Commissioners of Patents on the 5th December 1881.
WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex, Patent
Agent. "IMPROVED MEANS OF FIXING OR SECURING WINDOW GLASS." [A com-
munication from abroad by Thcopilus Tanner, of Osage, in the County of Otoe,
State of Nebraska, United States of America.]
This Invention consists of a rubber strip for holding and fastening window glass
in the sash.
"
The strips of rubber are placed upon the edges of the glass, and secured to the
sash by nails or screws. These strips are preferably of soft rubber, and they may
be made of any convenient length, which may be cut into short lengths as used to
suit the size of glass to be put in. The strips are preferably made triangular in
cross section, so as to fit closely in the corner of the sash. A slot is formed in the
upper side of the strip and parallel with the vertical side thereof, which slot is of
suitable depth and size to fit over the edge of the glass, and is narrower at the top
than at the bottom, so that a water tight joint will be formed between the rubber
and the glass on the outside of the window.
By the use of this fastener the panes of glass are held water and air-tight in the
sash; they are not liable to get loose and rattle, are not so easily broken as when
putty is used, and can be easily and quickly put in the sash.
Instead of using nails or screws for fastening the rubber strips, a recess may be
formed in the sash, into which the rubber may be placed a sufficient depth to secure
the same, or cement may be used for holding the strips.

WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex, Patent
Agent. "IMPROVED MEANS OF FIXING OR SECURING WINDOW GLASS." A coin- !
munication from abroad by Theopilus Tanner, of Osage, in the County of Otoe,
State of Nebraska, United States of America.
This Invention consists of a rubber strip for holding and fastening window glass
in the sash.
Reference is to be had to the accompanying Drawings forming part of this
Specification, in which similar letters of reference indicate corresponding parts in
both the Figures.
Figure 1 is a section of a window showing the Invention as it appears when
applied for holding the glass, and Figure 2 is a cross section of the strip of rubber
of the form it is prefered to make it.
A represents the strips of rubber which are placed upon the edges of the glass B
and secured to the sasli C by nails or screws, as shown in Figure 1. These strips
aro preferably of soft rubber, and they may be made of any convenient length,
which may be cut into short lengths as used to suit the size of glass to be put in.
The strips are preferably made triangular in cross section, so as to fit closely in the
corner of the sash. In the upper side of the strip, and parallel with the vertical
side thereof, is formed the slot a, which is of suitable depth and size to fit over the
edge of the glass, and is narrower at the top than at the bottom, so that a water-
tight joint will be formed between the rubber and the glass on the outside of the
window.
By the use of this fastener the panes of glass are held water and air-tight in the
sash; they are not liable to get loose and rattle, nor so easily broken as when putty
is used, and they can be easily and quickly put in the sash.
Instead of using nails or screws for fastening the rubber strips, a recess may be
formed in the sash, into which the rubber may be placed a sufficient depth to
secure the same, or cement may be used for holding the strips without departing
from the principle of the Invention.
Having described the nature of the said Invention and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the
hereinbefore in part recited Letters Patent is,-
As an article of manufacture a fastener for window glass, consisting of the
rubber strip A provided with the slot a, narrower at the top than the bottom, to
receive and hold the edge of the glass, substantially as and for the purposes set
forth.
In witness whereof, I, the said William Clark, have hereunto set my
