Description
Patented June 3, 1930 UNITED: STATES WILLIAM LOUDEN', or FAIRFIELD, IOWA, mssie ton To THE 'i ounnn' M AoHrNfiitYg- COMPANY, or FAIRFIELD, IOWA, A CORPORATION o'F IOWA 'METALLI ANGLEBAR I Application filed May 20, l92 'S erial nb.'192,'975.
My invention relates to an improvement in a'rounded fillet B. Therefore, toretain "the the form of the inner corner of metal angle bars, having flanges set at approximately right angles to each other, whereby the bar will have a rounded recess in its inner corner instead of either the common rounded fillet or the so-called square root inner corner, in which two way angle bars have been heretofore made, the advantage of this rounded 1 recess construction will be hereafter set forth.
In the accompanying drawings forming a part of this specification, Fig. 1 is atransverse section of a metallic angle bar embodying my invention. Fig. 2 is the same showing the bar with a little modification connected to a member which may be used for supporting it, or for other purposes. Fig. 3 is a transverse section of an angle bar having the rounded fillet in its inner corner and also showing it connected to a member similar to that shown in F ig. 2, for supporting, or other purposes. Fig. 4. is a transverse section of an angle bar having the so-called square root inner corner.
Referring to the drawings A and A represent the flanges on all the angle bars which may be made the same width, or the flanges A may be made a little wider than the flanges A, as shown in the drawings. The only essential difference between all the bars is that my improved bar shown in Fig. 1 has the rounded recess E while the bar in Fig. 3 has the rounded fillet B, and the bar in Fig. 4
has the so-called square root inner corner. The angle bar in Fig. 2 in addition to having my rounded recess in its inner corner (which is not lettered) has two enlarged portions FF on its outer sides opposite the inner relater on.
Heretofore, angle bars have been generally made with the rounded fillets B of Fig. 3, because it is less trouble to make them that way than with the square root corner C of Fig.
cess, the purpose of which will be explained -s'quare'root" corner, the inner roll hastofbe frequently r'edressed which adds to the'expense and, causesthe roll to wear out sooner than if'it was formed to make the. rounded fillet. For a number of purposes the bar with the rounded fillet is as good as the bar with the square root inner corner, and sometimes better.
- There is, however, one use in which it not as good, and that is when the inner side-of the angle bar has to be connected'to ameniher having a rectangular.corner,such as there ison the members D." In 'suchcases, the angle bar having the roundedv fillet B cannot be closely connected with such a member. The purpose of .my invention is to produce an angle bar which can be closely connected with a member having a sharp rectangular corner, and also be as easily and cheaply rolled as if it had a rounded fillet.
I accomplish this by having formed on the inner roll to form the angle bar, an outwardly extended rounded portion which in operation will form therounded recess E shown in Fig. 1. With a roll of this form, the rounded recess can be as easily and as cheaply formed as the rounded fillet B, and as shown in Fig. 2 an angle bar having this rounded recess in its inner corner, can be as closely connected to a member having a rectangular corner as if more difficult and expensive to roll.
When the flanges of the angle bars are the same thickness throughout, this rounded recess will make them thinner opposite the recess. If this would weaken the bar it can be easily remedied by forming the outer roll to add portions F ,F to the flanges opposite the recess. Also, the flanges of the bar can be made thicker on their inner portions opposite the recess than on their outer edges, which is a common thing to do in the manufacture of angle bars. If there should be any liability of weakness opposite the groove IE, it can be easily overcome in either of these ways. When the enlarged portions F-F are added, they should be opposite the recess in the inflanges.
. it had a square root corner O which is much In Patent No. 1,699,333 is illustrated a use which has been made of my improved angle bar. The angle bars are used to form the top rail, or rails, of an animal stall, and are Ffconnected to the stall posts A as most plainly shown in Fig. 5 of said patent. This patent is referred to for the purpose of getting amore complete understanding of the uses which may be made of my improved angle bar.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. As an article of manufacture, an angle bar formed by rolling heated metal and having flanges at substantially right angle to each other, a rounded recess in its inner corner, said recess being extended into each of the adjacent portions of the flanges, substantially as shown and described.
v 2. As an article of manufacture, an angle bar formed by rolling heated metal and having flanges at substantially right angle to each other, a rounded recess in its inner corner, said recess being extended into each of the adjacent portions of the flanges, and extended portions on the outersides of the flanges oppositesaid recess, substantially as shown and for the purpose described.
WILLIAM LOUDEN.
