UNITED STATES PATENT OFFICE.

HENRY M. MYERS, OF BEAVER FALLS, PENNSYLVANIA.

BAR FOR MAKING SHOVELS.

SPECIFICATION forming part of Letters Patent No. 340,608, dated April 27, 1886.

Application filed March 27, I885. Renewed October 26, 1985. Serial No. 180,965. (No model.)

To all whom it may concern:

Be it known that I, HENRY M. MYERs, a citizen of the United States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in a new article of manufacture, a Rolled Bar for Making Blanks for Shovels, Spades, and Scoops; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a new article of manufacture-to wit, a rolled bar for forming blanks for making shovels, spades,and scoops; and it consists ofa flat bar of iron or steel having a series of indentations and projections on one edge of it, and adapted to be cut into sections for forming said blanks.

To enable others skilled in the art with which my invention is most nearly connected to make and use it, I willproceed to describe its construction and operation.

In the accompanying drawings, which form part of this specification, Figure 1 is a front elevation of a pair of rolls for making indentations and projections on one edge of a heated flat bar. Fig. 2 is a vertical and transverse section of the same at line no of Fig. 1. Fig. 3 is a top view or plan of a flat bar of iron or steel after passing through said rolls. Fig. 4 is a blank for a shovel, spade, or scoopthat is, it represents in perspective a section of the bar shown in Fig. 3.

In manufacturing blanks for makingshovels, spades, and scoops, I take a billet of iron or steel and heat it to the proper degree for forging it by placing said billet in an ordinary heating'furnace, the construction and manipulation of which is well understood, and therefore need not be further described. When the billet is heated to the proper degree for iorging, it is removed from the furnace and passed through rolls of the ordinary construction, for reducing it to a flat bar,which,whi1e in the heated condition, is passed through one of the grooves A of the roll B, in'the bottom of which grooves are a series of indentations, 0. (Shown plainly in Fig. 2.) By passing the flat bar D through the groove A in theroll B a series of indentations and projections are formed on one edge of it by the impinging action of the two rolls B E, as indicated in Fig. 2, whereby a bar is formed having projections F on one edge of it, as shown in Fig. 3, which bar may be cut into sections, as indicated by the dotted lines shown in Fig. 3, each section forminga blank (shown in Fig. 4) for the making of a shovel, spade, or scoop by any of the several methods known to the art.

The construction of the rolls shown in Figs. and 2 and their manipulation are well understood by the skilled roll-turner, and therefore need not be further described.

The advantages ofthe herein-described new article of manufacture will be apparent to shovel makers, for it will enable them to dispense with the forging process and skilled labor necessary to produce blanks for shovels, spades, and scoops, and it will enable them to obtain said blanks at about the price of bariron and bar-steel.

Having thus described my new article of manufacture, what I claim is-- A rolled bar for forming blanks for making shovels, spades, and scoops, said bar having a series of indentations and projections on one edge of it, and adapted to be cut into sections for making said blanks, substantially as herein described.

HENRY M. MYERS.
