Improvements in Angle Bars of Iron and Steel used in the Con-
struction of the Frames of Metallic Bedsteads and other Articles
of Metallic Furniture, and for other purposes.
I WILLIAM WEAVER VAUGHAN of London Works, Oldbury in the County of
Worcester, Iron Master do hereby declare the nature of this invention to be as
follows:-
The object of my invention is principally to produce angle bars of iron or steel
used in the construction of metallic bedsteads and furniture, of less weight than
ordinary angle bars without materially reducing their strength, the light angle bars
having the same general figure as ordinary angle bars so that the light angle bars
can be used by bedstead makers in place of the ordinary angle bars without any
change in the stocks chills or moulds used in the manufacture of the bedstead or
article of furniture.
My invention has the further object to facilitate the punching of the holes for
the sacking or lath studs in the horizontal webs of. the angle bars by reducing the
punching strain required to punch the said holes and providing a guide for the line
of punchings formed in the bar.
Although the light angle bars made according to my invention are particularly
applicable for use in the construction of metallic furniture yet they may also be
used for other purposes, where light angle bars are required; for example in the
construction of metallic tanks and vessels safes and the like.
I will describe my invention in connection with angle bars used in the con-
struction of metallic furniture.
According to my invention I form in each web or in one of the webs of the
angle bar and in the inner face of the middle thereof, during the rolling process by
which the angle bar is rolled, a shallow longitudinal groove, channel or depression
having a width, say, of about one third the width and of about one third the
thickness of the web, but I do not limit myself to any particular width and depth
of the groove, channel or depression. The said shallow groove, channel or depres-
sion extends the whole length of the web of the angle bar and thereby considerably
reduces the weight of the angle bar.
The continuous groove, channel or depression may have at a short distance apart,
transverse strengthening ribs or bracing pieces; or instead of using a continuous
groove, channel or depression with or without transverse ribs, as described, longi-
tudinal depressions at a short distance apart and end to end may be rolled in the
face of the angle bar for the same purpose.
As the groove, channel or depression is situated at the middle of the horizontal
web of the angle bar, the depth of metal to be punched in forming the holes for
the sacking or lath studs is less than in an ordinary angle bar and hence con-
siderably reduces the punching strain, the said groove, channel or depression
serving as a guide in punching the line of holes.
Although I prefer to make one continuous or intermittent longitudinal groove,
channel or depression in the middle of the inner face of the webs of the angle bar,
yet two or more narrow parallel longitudinal continuous or intermittent grooves or
depressions or transverse or diagonal grooves or depressions may be rolled therein
for reducing the weight of the angle bar. Or the same object may be attained by
rolling a continuous or intermittent sunken pattern or ornament preferably on the
vertical web of the angle bar.

page_text: I do not limit myself to making the webs of the angle bar flat as one or both of
the webs may have a curved figure in cross section given to it or them.

COMPLETE SPECIFICATION.
Improvements in Angle Bars of Iron and Steel used in the Con-
struction of the Frames of Metallic Bedsteads and other Articles
of Metallic Furniture, and for other purposes.
I, WILLIAM Weaver Vaughan, of London Works, Oldbury, in the County
of Worcester, Iron Master, do hereby declare the nature of my invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
The object of my invention is principally to produce angle bars of iron or steel
used in the construction of metallic bedsteads and furniture of less weight than
ordinary angle bars without materially reducing their strength, the light angle bars
having the same general figure as ordinary angle bars so that the light angle bars
can be used by bedstead makers in place of the ordinary angle bars without any
change in the stocks, chills or moulds used in the manufacture of the bedstead or
article of furniture.
My invention has the further object to facilitate the punching of the holes for
the sacking or lath studs in the horizontal webs of the angle bars by reducing the
punching strain required to punch the said holes and providing a guide for the line
of punchings formed in the bar.
Although the light angle bars made according to my invention are particularly
applicable for use in the construction of metallic furniture yet they may also be
used for other purposes, where light angle bars are required; for example in the
construction of metallic tanks and vessels, safes and the like.
I will describe my invention in connection with angle bars used in the con-
struction of metallic furniture.
According to my invention I form in each web or in one of the webs of the
angle bar and in the inner or outer face of the middle thereof, during the rolling
process by which the angle bar is rolled, a shallow longitudinal groove, channel or
depression having a width, say, of about one third the width and of about one third
the thickness of the web, but I do not limit myself to any particular width and
depth of the groove, channel or depression. The said shallow groove, channel or
depression extends the whole length of the web of the angle bar and thereby con-
siderably reduces the weight of the angle bar. The continuous groove, channel or
depression may have at a short distance apart, transverse strengthening ribs or
bracing pieces; or instead of using a continuous groove, channel or depression
with or without transverse ribs, as described, longitudinal depressions at a short
distance apart and end to end may be rolled in the face of the angle bar for the
same purpose.
As the groove channel or depression is situated at the middle of the horizontal
web of the angle bar, the depth of metal to be punched in forming the holes for
the sacking or lath studs is less than in an ordinary angle bar and hence con-
siderably reduces the punching strain, the said groove, channel or depression
serving as a guide in punching the line of holes.
Although I prefer to make one continuous or intermittent longitudinal groove,
channel or depression in the middle of the inner face of the webs of the angle bar,
yet two or more narrow parallel longitudinal continuous or intermittent grooves or
depressions or transverse or diagonal grooves or depressions may be rolled in the
inner or outer face of the webs for reducing the weight of the angle bar. Or the

page_text: same object may be attained by rolling a continuous or intermittent sunken pattern
or ornament preferably on the vertical web of the angle bar.
I do not limit myself to making the webs of the angle bar flat as one or both of
the webs may have a curved figure in cross section given to it or them.
Figure 1 of the accompanying drawing represents in perspective one kind of
angle bar made according to my invention. In this angle bar a continuous shallow
groove, channel or depression is rolled in the inner faces of both the webs of the
angle bar, the said grooves or channels extending from end to end of the bar. The
horizontal web of the angle bar is marked a and the vertical web is marked b and
the continuous shallow groove, channel or depression in each of the said webs is
marked c.
As the groove, channel or depression c is situated at or about the
middle of the horizontal web a of the angle bar, the depth of metal to be
punched in forming the holes for the sacking or lath studs is less than in
an ordinary angle bar, and hence considerably reduces the punching strain,
the said groove, channel or depression c serving as a guide in punching the line
of holes.
Figure 2 represents a modification of the angle bar represented in Figure 1. In
this modified bar, the grooved or channelled vertical web b is the same as that
represented in Figure 1 the horizontal web a is however without a groove or
channel but the said web a is reduced in thickness so as to make it of the same or
nearly the same weight as the grooved web a of the bar Figure 1.
Figure 3 represents another modified angle bar made according to my invention.
In this bar the horizontal web a is made of less width than that represented in
Figure 1 and is provided with a continuous groove, channel or depression c; or the
narrow horizontal web a may be without a continuous groove channel or depression
and the thickness of the metal be reduced as represented in Figure 4.
When both webs of the angle bar are provided with continuous grooves or
channels the said grooves or channels may be made in both faces of the webs as
represented in Figure 5, where the continuous grooves or channels in both faces of
the webs a, bare marked d, d.
Or a continuous groove may be made in the outer face only of the vertical web b
the horizontal web a being ungrooved and of the ordinary thickness as represented
in Figure 6, where the groove or channel in the outer face of the vertical web b is
marked e.
Or a continuous groove or channel may be made in the outer face of the
horizontal web and in the inner face of the vertical web as represented in Figure 7,
where the continuous groove or channel in the horizontal web a is marked ƒ and
that in the vertical web is marked g. Or in place of the last described con-
tinuous channels or depressions, two (or more) parallel narrow grooves may be made
in one or in each of the webs of the angle bar as represented in Figure 8, the
grooves in the horizontal web a being marked and those in the vertical web b
being marked i.
Figure 9 represents in an inverted position, an angle bar in which the shallow
groove or channel k extending along the inner face of the vertical web b of the
bar is provided with transverse strengthening ribs or bracing pieces marked 7.
Figure 10 represents in an inverted position an angle bar in which longitudinal
depressions at a short distance apart and arranged end to end are made in the
vertical web 6 instead of a continuous groove, channel or depression. The said
short grooves or depressions in the angle bar are marked m.
Grooves or depressions of the kinds represented in Figures 9 and 10 may be
applied to both webs of the angle bars and may be rolled in one or in both faces
of the webs.
The angle of the bar may either be straight or rounded.
Instead of making the web or webs of the angle bar with a continuous groove
or grooves as before described for reducing the weight of the bar, the same
object may be attained by rolling tapering longitudinal depressions in one or in
both webs so that the bar is thicker at the middle of the length than at the

page_text: ends; that is, the metal gradually tapers from the middle to the ends of the
webs each rise and depression in the webs giving strength where needed and
lightening the bar at the points of support. An angle bar having a length,
say of six feet in which the horizontal web is thickest at its middle and thinnest
at its ends, as last described is represented in an inverted position in Figure 11.
The thick middle part of the horizontal web a of the angle bar is marked p and
the thinner ends are marked q, q. The way in which the thickness of the metal
gradually diminishes from the middle p to the ends qq of the bar is shown in the
drawing.
Although I have represented in Figure 11 a length of angle bar equal only to
the side of a bedstead yet angle iron of that kind may be rolled in lengths equal
to two three or more lengths of that shown, and the long bar cut into the required
lengths. The compound bar thus rolled resembles a series of the angle bars
Figure 11 joined end to end.
Having now particularly described and ascertained the nature of my invention
and the manner in which the same is to be performed I declare that I claim as
my invention:-
The improvements in angle bars of iron and steel used in the construction of the
frames of metallic bedsteads and other articles of metallic furniture and for other
purposes hereinbefore described and illustrated in the accompanying drawing;
that is to say making in one or in both of the webs of the angle bars and in one
or in both faces of the said webs, shallow grooves, channels or depressions of
the kinds described and illustrated; or making the webs of the lengths of angle
bars thicker at their middles than at their ends as described and illustrated,
the several methods described and illustrated of disposing of or arranging the
metal of the angle bars effecting a maximum of strength with a minimum weight
.of metal.
