HERMAN S. ALBRECHT, OF ST. LOUIS, MISSOURI.
METALLIC BILLET R BAR.
Application filed May 9, 1921. Serial No. 468,080.
To all whom. t may concern.'
Be it known that I, HERMAN S. ALBRECHT, a citizen of the United States, residing at the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Metallic Billets or Bars, of which the following is a specification. l
This invention relates to improvements in metallic billets or bars, and consists in the novel construction hereinafter disclosed. An object of the invention is to provide a metallic billet or bar having indentations' or score lines extending into the surface of the metal thereof a suflicient depth so that the bar may be readily'broken, said inden-l tations or score lines being equally spaced so that the bar when broken will form slugs of substantially uniform cubic content.
In the drawing Fig. 1 is a side elevation of a round bar including the present invention.
Fig. 2 is a cross section on the line 2--2 of Fi 1.-
Fig. 3 illustrates, in side elevation, a m0dified form of bar including the invention.
Fig. 4 is a cross section on the line -l of Flg. 3.
Fig. 5 illustrates, in side elevation, a further modification of the bar including the invention.
Fig. 6 is a cross section on the line 6 6 of F 1g. 5.
Fig. 7 is a further modification of a bar, in side elevation, including the invention. Fig. 8 is a cross section on the line 8-8l of Flg. 7.
' or score lines 2 substantially cutting through 45 the body of the bar, leaving only a relatively thin connection 3 between the different sections el thereof. By rolling the bar the material thereof is pressed to shape, the molecular arrangement of the lnetal being modified and set in the. changed shape by the pressure without loss of material, as in the case of cutting the bar to the shape desired.
A bar thus formed may be readily broken, the segments thereof being of substantially the same cubic content.
In practice itl has been found very difficult to saw or otherwise sever 'the barinto uniform sections.' In the bar 0f the present in- 60 vention as the indentations are mechanically formed at uniform predetermined intervals` the sections when broken from the bar are uniform in cubic content.
I claim.
A rolled metallic billet or bar, composed of a series of axially alined spherical bodies having their spherical surfaces in Contact and integrally united.
