PROVISIONAL SPECIFICATION left by the said Thomas Hughes at the
Office of the Commissioners of Patents on the 15th July 1882.
THOMAS HUGHES of Market Drayton in the County of Salop
"AN IMPROVED
METALLIC GLAZING BAR AND FITTINGS FOR GLAZING WITHOUT THE USE OF PUTTY-
OR PAINT"
The Invention has for its object an improved metallic glazing bar and fittings
for glazing without the use of putty or paint.
.
For this purpose I employ metal tubes with a slit or opening along their entire
length, of a similar character to those produced by drawing a strip of metal
through a die; the edges of the metal along the said slit or opening I turn back
so as to form a groove along each side of the slit or opening.. I place two of these
open tubes back to back with the slits or openings outwards and I connect them
together by strips of metal extending from the slit or opening of one tube across
the two tubes to the slit or opening of the other tube, one of such strips being
placed on each side of the pair of tubes and being passed into the grooves aforesaid
where a welted seam is formed so as to connect the said tubes firmly together and
produce a smooth outer surface and a good finish to the bar.
The tubes and the covering strips may however be connected together by other
means, and instead of building up the said glazing bars as above described they
may be otherwise formed.
The glass is passed into the slits or openings of the tubes aforesaid where it is
held partly by the spring of the said tubes and partly by T formed wedges pushed
into the ends of the said bars which wedges by their heads form a neat finish to
the bar.

the bar.
In the arrangement represented at Figures 7 to 12 the glazing bar is built up of
two tubes a with longitudinal slits or openings a'. therein and placed back to back
and connected together by strips 6 but instead of turning back the edges of the
metal along the slits or openings a'. and inserting therein the edges of the strips b
as before described I leave the edges of the metal along the slits or openings a¹
plain and I turn over the edges of the strips 6 so as to form grooves along the
edges thereof into which are received the edges of the tubes a along the slits or
openings a¹, thereby forming welted seams of a similar character to those shewn
and described with respect to Figures 1 to 6 but with the parts forming such
seams reversed and instead of employing a T formed wedge o pushed endwise into
the bars the part c is formed so as to be placed transversely of the end of the tube
the lower part thereof being passed into a slot or opening a², formed in a piece of
metal attached to the said bar as shewn.
The tubes a and covering strips b. may however be connected together by
other means and instead of building up the said glazing bars, as above described
they may be otherwise formed so long as such bars are formed of tubes a and
covering or connecting strips 6 as above described.
Having thus described the nature of my said Invention and the mode in which
I carry the same into effect I would have it understood that I do not claim
generally in the construction of glazing bars, the employment of two tubes a. ɑ.
connected together back to back as such is well known and in use but what I do
claim is the improved glazing bar and fittings substantially as herein described
and consisting of two tubes a with slits or openings a¹. connecting strips b. and
stops or fittings c.
In witness whereof I the said Thomas Hughes have hereunto set my hand
and seal this twelfth day of January in the year of our Lord One thousand
eight hundred and eighty three.
