JOHN s. SURBAUGH, or VINCENNES, INDIANA.

SHOVEL AND SCOOP.

To all whom it may concern Be it known that I, JOHN S. Simulation, a citizen of the United States, residing at Vincennes, in the county of Knox and State of Indiana, have invented certain new and useful-Improvements in Shovels and Scoops,

of which the following is a specification.

This invention relates to shovels and scoops of the hollow back type, and is an improvement over the construction shown in U. S. Letters Patent No. 1,085,642, issued to me on February 3, 1914.

The object of the invention consists in the .,provision of certain means for increasing the rigidity of the shovel and scoop blades where the material in forming said blades is necessarily weakened during the crimping operation.

A further object of the invention consists in providing certain reinforcing means in the blades of scoops and shovels wherein the material of the blades between the reinforcing means and the shank member now left as shown in the Letters Patent aforesaid is also strengthened by said reinforcing means.

A still further object of the invention is to provide reinforced shovel and scoop blades which will be economical to manufacture, simple in construction, light in weight, and so reinforced to permit scoops and shovels made of light material to be used in doing heavy work.

I accomplish the above objects of the invention by means of the construction shown in the accompanying drawings, forming a part of this specification, in which Figure 1 is a top or plan view. of a blank,

as it is cut by the die from the metal sheet, from which the shovel and scoop blades are subsequently formed. Fig. 2 is a top or plan view of one of. the blanks shown in Fig. lconverted into a finished shovel or scoop.- Fig. 3 shows a modified form in which the number of the reinforcing means or ribs is increased. Fig. 4 is a modified view of a different type of shovel and scoop formed of a unit blank of somewhat different outline from that shown in Fig. 1.

Referring to the drawings, 10 represents one ofthe niiinerous styles of blanks cut from the sheet metal stock to form a particular kind. of a shovel or scoop. It will be understood, of course, that in varying the shape of the blank, a scoop or shovel of a different outline can be produced. It is be- Specification of Letters 1'atent.

Application filed January 19, 1915. Serial No. 3,097.

lieved that the description .relating to the blank shown in Fig. 1 and the shovel or .scoop blade produced therefrom will be sufficient to clearly set forth the object of the present invention.

. When the blank 10, shown in Fig. 1 of the drawings, is placed in the crimping floor 12 of the blank being undisturbed so that a pocket is formed for sustaining the material to be worked upon. It will be noted that the'blank 10 is reduced in width at one end into a narrower member or shank machine, theside edges of the blank. are forced upwardly into the members 11, the

15 which is subsequently converted into a roll or tube 16 adapted to receive the ordinary shovel or .scoop handle, not shown. The roll or tube 16 extends across the raised members 11 of the blank to reinforce them and is bifurcated so as to enter the flat portion 12 of the blank at different. points. Line 17 indicates-or defines the point where the blank is bent to formthe raised members 11,'which bending necessarily weakens the material-from which the blade'is formed, and it is the object of the bifurcated ends 18 of the roll 16 to strengthen these weakened points of-the blank 10. The shovel and scoop blade when formed with a roll 16 extending across the raisedmembers 11 and bifurcated to extend across the flat portion 12 of the blade also reinforces the blank, where the roll 16 merges with the members'll as at- 20. By means of this construction one part of the roll 16 aids the other parts of the roll in reinforcing the entire blade unit more than is possible where the rolls or reinforcing. ribs are separated as shown in the Letters Patent aforesaid.

The matter of increasing the rigidity and in the strengthening of the scoop and shovel blades may be additionally extended by increasing the number of the reinforcing ends 18'from the roll 16, as shown in Fig. 3 of the drawings.

Fig. 4 illustrates practically the same conif desired.

I claim: 1. A shovel or scoop blade comprising a unit blank provided with an integral shank,

said blank being crimped to provide a flat portion with raised sides and back, said strengthening roll and being bifurcated to provide an increased number of strengthening rolls to enter the flat portion of the blank at difierent points.

3. A shovel or scoop blade comprising a unit blank provided with an integral shank, said blank being crimped to provide a flat portion with raised sides and back, said shank being rolled into a hollow tube, adapted to receive a handle, and extending across the raised back member in theform of a strengthening roll and thence forked to provide an increased number of strengthening rolls to enter the flat portionof the blank at different points.

4. A shovel or scoop blade comprising a unit blank provided with an integral shank, said blank being crimped to provide. a fiat portion with raised sides and back, said shank being rolled into a hollow tube adapted to support a handle and extending into the raised back in the form of a strengthening roll and thence forked to provide an increased number of strengthening rolls extending into the fiat portion of the blade.

5. A sheet metal shovel blade pressedto form a bottom, a rear wall, a handle socket merging into said rear wall, and ribs merging into said handle socket at said rear wall, said ribs being separated from each other at the junction of said rear wall and bottom.

6. A sheet metal shovel blade pressed to form a bottom, a rear wall, a handle socket merging into said rear wall, and a pair of ribs merging into said handle socket at said rear wall and diverging from said rear wall, said ribs being approximately straight and approximately parallel with .each other at points on opposite sides of the transverse center of said bottom.

7. A sheet metal blank pressed to form a shovel blade, a handle socket merging into said blade, and ribs merging with said handle socket near the junction of the handle socket and blade, said ribs extending away from said handle socket and entering the blade at different places.

8. A shovel or scoop made from a single blank comprising a blade having a bottom, raised sides and back, an integral shank rolled into a tube, adapted to receive a handle, said tube having one end forked,

the forked ends entering the blade at dif- 'ferent points.

In witness whereof, I, have hereunto set my hand and seal at Carterville, Illinois, this seventh day of January, A. D. one thousand nine hundred and fifteen.
