PROVISIONAL SPECIFICATION.
Improvements in Metal Strips for Sash Bars, also for Construction
of or Strengthening Sash and other Frames for Holding Glass.
I, STEPHEN TUDDENHAM of 208 Lambeth Road, London, S.E. Art Metal Worker
& Blacksmith do hereby declare the nature of this invention to be as follows :-
In carrying out my invention, I provide strips of Iron, Steel, Copper, Brass, Zinc
or other metal (hereinafter called Metal Strips) of any desired width and thickness,
such strips being ribbed, or swaged, longitudinally.
These Metal Strips are left plain, or may be crimped, fluted, or corrugated, on one
or both edges, at right angles or obliquely to the rib or swage, and may be produced
in the required form by rolling between suitable rollers, or by stamping with dies, or
cast to required form.
In applying this invention to Sash Bars I use two of these Metal Strips, between
which I place a Strip Bar or Rod of metal, which is held in position by the grooves
formed by the rib or swage in the Metal Strips, which are held together by means
of Screws, Bolts & Nuts, Rivets or other preferred method, thus forming a section
in the shape of the letter H, having sufficient space between the Metal Strips to allow
for the thickness of the glass to be contained.
In the construction of Sash or other Frames for holding Glass, 1 apply these Metal
Strips thus-
1. I use Sash Bars as previously described which are joined at the corners or where
else necessary by Plates, Screws, Bolts & Nuts, Rivets Soldering or Brazing.
2. By using the Metal Strips edgeways shaped for Frame required, with the rib
or swage on the outside, thus forming a groove or recess on the inside of the
frame for containing the Glass-These Frames are secured at the angles or where
else required by Plates, Screws, Bolts & Nuts, Rivets Soldering or Brazing.
3. By using the Metal Strips which by rolling or other preferred method are
formed to an angular section, the Glass being held in position with putty―These
Frames are also secured at the angles or where else required by Plates, Screws,
Bolts & Nuts, Rivets, Soldering or Brazing.
For strengthening Panels of Lead Lights or other Frames for holding Glass,
I use the Metal Strips on one side of the Glazing Lead or other Sash Bar or
Framing, and where greater strength is required, I use the Metal Strips on both
sides; in either case the Metal Strips being secured by Screws, Bolts & Nuts, Rivets
Soldering or other preferred means.
COMPLETE SPECIFICATION.
Improvements in Metal Strips for Sash Bars, also for Construction
of or Strengthening Sash and other Frames for Holding Glass,
I, STEPHEN TUDDENHAM, of 208, Lambeth Road, London, S.E., Art Metal Worker
do hereby declare the nature of my invention for IMPROVEMENTS IN METAL STRIPS.
FOR SASH BARS, ALSO FOR CONSTRUCTION OF, OR STRENGTHENING SASH AND OTHER
FRAMES FOR HOLDING GLASS, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
In carrying out my invention I provide strips of Iron, Steel, Copper, Brass, Zinc
or other preferred metal, of any desired width and thickness, such strips being Ribbed
or Swaged longitudinally.
These Strips are left plain, or may be Crimped, Fluted or Corrugated, on one or

page_text: both edges, at right angles or obliquely to the Rib or Swage, and may be produced in
the required form by rolling between suitable Rollers, or by stamping with Dies, or
cast as desired.
In applying this invention to Sash Bars I use two of these Metal Strips, between
.which I place a Strip, Bar, or Rod of Metal, which is held in position by the grooves
formed by the Rib or Swage in the Metal Strips which are held together by means
of Screws, Bolts & Nuts, Rivets or other preferred method, thus forming a section in
the shape of the letter H having sufficient space between the Metal Strips to allow
for the thickness of the glass to be contained.
In the construction of Sash or other Frames for holding Glass, I apply these Metal
Strips thus―
1. I use Sash Bars as previously described which are joined, at corners or where
necessary, by plates screws, Bolts & Nuts Rivets, Soldering or Brazing.
2. By using the Metal Strips edgeways, shaped as for Frame required with the Rib
or Swage on the outside, thus forming a groove or recess on the inside of frame for
containing the Glass. These Frames are secured at angles or where else required, by
Plates, Screws, Bolts & Nuts, Rivets, Soldering or Brazing.
3. By using the Metal Strips which by rolling or other preferred method are
formed to an angular section, the Glass being held in position with putty. These
Frames are also secured at angles or where else required by Plates, Screws, Bolts
& Nuts, Rivets, Soldering or Brazing.
For strengthening Panels of Lead Lights or other Frames for holding Glass, I use
the Metal Strips on one side of the Glazing Lead or other Sash Bar or Framing-
Where greater strength is required I use the Metal Strips on both sides, in either
case the Metal Strips being secured by Screws, Bolts & Nuts, Rivets, soldering or
other preferred means.
I will now proceed to describe with reference to the accompanying drawings the
manner in which my invention is to be performed.
Fig's. 1. 2. represent Strips of Iron, Steel, Copper, Brass, Zinc, or other metal, of
any desired length, width & thickness, such Strips being Ribbed or Swaged, longi-
tudinally. These Strips may be plain on both sides of the longitudinal Rib or Swage,
as Fig. 1-a. b. are one side plain and the other side Crimped Fluted or Corrugated
as Fig. 1. c. d. or both sides may be Crimped, Fluted or Corrugated as Fig. 2. a, b.—
c. d. Fig. 3. represents the Strips where the edges are formed at any desired angle
and may be plain on both sides, or plain on one side and Crimped, Fluted or
Corrugated on other side, or may be Crimped, Fluted, or Corrugated on both sides of
longitudinal Rib or Swage as described and illustrated Figs. 1-2. The Crimping,
Fluting and Corrugating for all these strips may be either angular or undulated.
For brevity, in this Specification, the Strips of Iron, Steel, Copper, Brass, Zinc or
other metal, I hereinafter call, "Strips of Metal," and the drawings Fig's. 4 to 16
inclusive, are illustrated with plain sides, but Strips of metal either plain, Crimped,
Fluted or Corrugated as sections described and illustrated Figs. 1-2-3 are applicable.

Having now described the nature of my invention, and the manner in which it
is to be performed, I declare that what I claim as my invention for, "Improvements
in Metal Strips for Sash Bars, also for Construction of or Strengthening Sash and
other Frames for holding Glass ;" is
