MINER S SHOVEL.
Specification of Letters Patent.
' Patented Jan. 28, 1908.
Application filed January 2| 1907- Serial No. 3504Z4u To all whom it may concern:
Be it known that I, DAVID B. Lnwrs, a citizen of the United States, and a resident of Bisbee, in the county of Cochise and Territory of Arizona, have invented certain new and useful Improvements in Miners Shovels, of which the following is a specification.
This invention relates to hand shovels and more especially to square miners shovels.
The object of the invention is to provide an improved shovel blade for taking up rock and ore which will slip easily thereunder and scoop it up clean.
In the accompanying drawings, Figure 1 represents a perspective view of a shovel blade embodying this invention; Fig. 2 represents a longitudinal section thereof; Fig. 3 represents a top plan view of the blade; Fig. 4 represents a bottom plan view of the blade.
In the embodiment illustrated, a square blade 1 is shown, the upper or rear end of which is of the ordinary construction, being bent upwardly and having an upstruck apertured portion 2 to receive the handle 3. The side edges 4 and 5 of the blade are curved upwardly at the rear end thereof and in clined gradually downwardly and outwardly from the rear toward the front and merge into the flat front end near the middle of the l blade about three inches, more or less, from the edge of said front end. These side edges are parallel with each other and lie in the same plane, and the front portion of the blade being fiat across the entire width thereof presents no obstructions to the coal or ore to be elevated, and permits the blade to slip readily thereunder with the least possible resistance. By this construction the inner faces of the side edges are arranged in approximately a horizontal plane.
I claim as my invention 1 A square shovel blade composed of a single thin sheet of metal having its front portion flat and straight across its entire width with the sides thereof curved upwardly at the rear end of the blade and bent outwardly and downwardly toward the front, merging into said flat front portion near the middle of the blade and with their inner faces lying in approximately a horizontal plane, said sheet having its rear end bent upwardly from a point beyond the middle, whereby a central depression is formed to receive the material to be lifted.
DAVID B. LEWIS.
