ROBERT R. SINGER, OF PI'ITSBURG, PENNSYLVANIA.
BLANK FOR VEHICLE-TONGU ES, 80C.
iPEOIFICA'LION forming part of Letters Patent No. 507,176, dated October 24, 1893.
Application filed January 28, 1893. $erial No. 460,068. (No model.)
To all whom it may concern.-
Be it known that 1, ROBERT R. SINGER, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Blanks for Vehicle-Tongues, &c., of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specificat'on, in which- Figure 1 is a plan view of my improved blank, showing one of the forms employed for a singletree or doubletree. Fig. 2 is a longitudinal section of the same; and Fig. 3 is a top plan view of the finished article.
My invention relates to the manufacture of hollow metallic articles of sheet metal, such as vehicle tongues, double-trees, whiffle-trees, brake-beams, &c., and is designed to afford an improved blank which, when bent into form, will afford a much stronger and more serviceable article than has been possible heretofore.
To that end it consists in a blank which tapers longitudinally in thickness toward the ends, but whose cross-section throughout is of uniform thickness, and also in the article formed therefrom.
In the drawings, 2 indicatesa blank, in this case designed for a double-tree or single-tree,
the blank being thickest at the point 3, and tapering thence toward each end, as shown in Fig. 2. In the case shown of a whiffie-tree, the thicker portion is approximately at the center of its length, and in each case the greater amount of metal is used at the point where the greatest strain is brought to bear thereon.
The advantages of my construction are obvious, since a much lighter and cheaper construction is attained, while the same strength is present as in a blank of a uniform thickness throughout.
Many variations may be made in the general form of the blank without departure .from my invention, since What I claim is A tubular metal article, having a thickened portion in its length, and tapering lengthwise from such portion toward each end; substantially as described.
In testimony whereof I have hereunto set my hand.
ROBT. R. SIN GER.
