SHOVEL.

Specification of Letters Patent.

Application filed January 27, 1911.

Patented July 4, 1911. Serial No. 604,962.

To all whom it may concern:

Be it known that I, GUsTAvE F. DANIEL- soN, a citizen of the United States of America, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Shovels, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to shovels, and has for its object the provision of an article of this nature which will permit its manufacture from light-weight stock and yet will be as strong and lon -lived as the ordinary shovel made from stock of nearly twice the thickness. These results are attained by the peculiar crimping or ribbing of the edges of the shovel blade, in the man ner illustrated in the accompanying drawings, in which Figure 1 shows a top view of a shovel embodying my improvement; Fig. 2 is a longitudinal section thereof, on line 2-2 of Fig. 1; Fig. 3 represents a section of the front edge on line 33 of Fig. 1, on an enlarged scale, and Fig. 1 illustrates a section of one of the side-edges, on line 14: of Fig. l, on an enlarged scale.

Referring to the drawings, the shovel blade 10 is preferably longitudinally arcuate (see Fig. 2) and has a series of

depressions

11, 12, in its upper face, thus forming on the underside thereof a series of stiffening members or ribs which stiffen the blade against straightening out. The arcuate formof the blade, longitudinally, will of course stiffen, per 86, the blade against bending laterally, and this stiifness is still further increased by forming the depressions 12 with branches 12 leading toward the front-edge corners of the blade, so that the front-edge portion even if fiat or straight will yet be very stiff. Furthermore the side edges of the blade are bent upward from the body, as shown at 13, thus forming an upward longitudinal rib which tends to preserve the longitudinal curvature of the blade, and this edge is again reinforced against cross-strains, (such as the edge would receive when striking a side-blow by an outward bend 14; which extends along both side-edges and the backedge, but is indented at the latter point to form a notch 15 for the reception of the handle H which may be of any desired form and secured to the blade near the middle thereof by a staple S.

The front edge of the blade is straight and flat so as to scoop-up material readily, and this edge really constitutes thewearsubjected portion of the device. In order to increase its rigidity and, at the same time, increase its resistance to fraying-out, the metal is doubled upon itself as at 16 and tightly compressed to prevent water from entering the bend and the consequentrusting or corrosion of the metal at that point.

While, as above stated, the double thickness of metal naturally stifl'ens the edge, I deem it of further advantage to form a bead 17 longitudinally and in parallelism with the front edge, thus still more strengthening the edge against buckling, and the end-edge 16 of the back fold is forced into tight contact with the underside of the bead 17, thus bringing this end-edge above the under level of back-fold and shovel-body, so that, therefore, any liability of fraying will be still further reduced.

In some instances it may be preferable to dispense with the staple S; and at S is shown a pocket which is stamped-out from the body of the blade and into which the lower end of the handle can. be wedged. It is evident that a plain strap similarly punched, but without the pocket feature, will answer the same purpose as far as holding the handle is concerned.

I claim:

A shovel-blade having at its front edg an upwardly extending strengthening bead and having its front edge doubled upon itself, the extreme end-edge resting in close contact with the hollow underside of said bead.

In testimony whereof I aflix my signature in presence of two witnesses.

GUSTAVE F. DANIELSON.
