..!
The object of my invention is to simplify and cheapen glazing at the same time
it being more durable than the existing methods.
יו.
I employ a glazing bar of rolled iron or steel consisting of a Tiron with vertical
arms at the end of the T which project upwards and have recesses in their bearing
ends for lead or other soft material for the glass to bed upon, the top of the Tand
its extended ends form a chamber the length of the roof or glazing, studs are
screwed or tapped into the centre of the glazing bar at suitable distances with nuts
at their other ends for holding down and securing in position the zine or lead caps
which are placed thereon and rest and secure the glass, rendering the same düst
and weather proof.

I ROBERT ROBERTS of Brighouse Fields, Rastrick, Brighouse, in the County
of York, Plumber and Glazier, 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:→

DESCRIPTION OF DRAWINGS.,
Fig. 1 a sectional elevation of T iron or bar.
Fig. 2 is a sectional elevation of cap.
Fig. 3 is a plan of underside of cap showing method of attaching same to
the Tiron or bar.
Fig. 4 is a sectional elevation of my improved system of glazing without cap.
Fig. 5 is a sectional elevation of my improved system of glazing showing cap in
position and method of securing same.
In my improved system of glazing, I employ a glazing bar of rolled iron or steel,
consisting of a T iron A, with vertical arms B at the end of the T which project
upwards and have recesses C in-their bearing ends for lead, asbestos, indiarubber
or other suitable soft material D for the glass E to bed upon. The top of
the Tiron or bar and its extended ends form a chamber F the length of the roof
or glazing suitable screws, bolts or studs G are screwed or tapped into the centre
of the glazing bar: A at suitable distances apart for holding down and securing in
position, the zinc, lead, or other suitable metallic caps H, which rest on and secure
the glass in position rendering the same dust and weather proof.
For effectually and quickly securing the caps in position I preferably provide or
attach to the said caps underneath a series of plates J (see Figs. 2 and 3) in which
are keyhole slots K. When fixing the cap H, the heads of the studs or screws G
pass through the enlarged end of the slots K and the cap then slides down the bar
until the screws, studs or bolts G reaches the opposite end of the slots K, (as
shown in dotted lines at Fig. 3) holding the said caps, firmly and securely in
positioni; by sliding the caps back until the heads of the screws or bolts G are
opposite the enlarged end of the slots K, they can be easily and quickly removed
or replaced.
Also if desired the channel or chambor F of the T iron or bar may have a thin
covering of lead. or other non-corrosive metal. so as to preserve the bar from
corrosion or similar effects.
. Also the bar may have a hole at the bottom, to allow the moisture or condensation
to pass away, and the vertical rib may be taper (see Fig. 1) of any desired
depth..
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that I am aware
that T-shaped glazing-bars formed with channels lined with lead are not new, and
I am also aware that glazing-bars with grooves to receive packing have been used
before, and I make no claim to these parts separately, but what I claim is:-
1. Constructing the soft metal glazing eap, and, securing, same to the Tiron or
bar, in the manner substantially as shown and described.
2. A glazing bar A having vertical arms B with recesses C, and packing D,
studs screws or bolts G in combination with soft metal cap H, arranged and secured
in the manner and for the purposes substantially as shown and described.
