NEGAUNEE, MICHIGAN SNOW SHOVEL Application filed October '8,

This invention relates to hand snow shovels of that general type employing a wooden blade having a sheathed cutting or scraping edge, and a handle connected to the blade.

My improvements relate, more particularly, to l or shoe for the the metal sheatn cutting edge of the blade, the construction of the blade, and the manner in which the handle is secured to the blade. The objects of the present invention are: to'provide an improved hardened steel or cast iron metal shoe or protector for the edge of the blade and one which engages the blade in an improved manner; to provide a wooden blade having sides and a back for the purpose of retaining the snow, and detachable connections between the sides, back, and blade so that replacement may be effected if any one of said parts becomes unduly worn; to provide improved the handle to the blade and to the back, for the purpose of mutually strengthening the blade, its back, and the handle where these parts are joined together, so that the strain will be distributed; and to provide an improved snow shovel wherein the back and the sides of the blade are relatively strong and the manner in which the handle is connected to the blade and back will result in suitable balancing so that there will be little likelihood of the shovel tipping sidewise when in use.

The improved re-inforcing metal shoe or tip for the blade and the connection between the handle and the blade, is located on the the wear and minimize the wear on the Wooden blade itself.

The improved shoe or protector for the edge of the blade is combined therewith in a new manner, preventing splitting of the blade and enabling the shovel to be vigorously used without danger of damage. Furthermore, with the improved shoe for the edge of the blade, the shovel can be reversed and used for scraping snow from walks.

Further objects and features of construction are set forth hereinafter and the novel parts and combina ions involved in the shovel are recited in the appended claims.

In the accompanying drawing:

1931. Serial No. 567,715.

Figure 1 is a perspective view; Fig. 2 1s a bottom plan view; and Fig. 3 1s a section on the line 33, Fig. 2.

The bottom or body of the wooden blade appears at 1, the sides thereof are shown at 2 and the back appears at 3. The sides 2 and back 3 are detachably connected to the bottom 1 by screws 1 whereby any one of these parts may be disconnected for purposes of replacement, when necessary. Furthermore, the provision of sides and a back strengthens the bottom 1 and provides a scoop-like shovel adapted to retain the snow and prevent it from spilling. Any suitable wood may be used for the parts 1, 2 and 3.

The forward edge of the bottom 1 of the blade is rounded or bevelled at 5 and its upper edge is rabbeted at 6.

. My improved hardened steel or cast iron sheath or shoe 7 has a relatively sharp scraping or cutting edge 8, and a rearwardly extending lip 9, which lies in the rabbet 6 and abuts the wall thereof.

The shoe 7 is provided on its bottom with a relatively thick and wide part 10, which overlies the curved surface 5 of the bottom 1 and is provided with tongues or lugs 11, which are connected to the bottom by screws or other suitable fastenings 12.

The foregoing construction provides a rigid metal sheath or shoe at the cutting and scraping edge of the shovel which protects theforward edge of the bottom 1- against abrasion, splitting, and wear. 7 is worn to an undue extent, impairing its cutting and scraping properties, it is only necessary toremove the screws 12 and sub-' stitute another shoe. The provision of the shoe 7. enables the snow to readily pass onto the shovel-blade because the top surface of said shoe lies flush with the top surface ,of the bottom of the blade. By reversing the shovel, the snow may be readily scraped from the pavement and ice may be broken up.

The handle 13, which is of any suitable wood, has a reversely curved lower end 14:, which is connected to the bottom 1 and the back-3 by bolts 15 and 16, respectively, these connections being so arranged that an im- VVhen the shoe Y Fe proved result in regard to bracing and strength, is obtained.

The bolt 15 passes through the bottom 1 and through a re-inforcing wear plate 17, which latter extends crosswise of the bottom and is detachably connected thereto by screws 18. A nut 19 on bolt 15, bears against the bracing and wear plate 17.

The wear plate 1'? possesses the triple advantage of relieving the bottom, to a material degree, of abrasion; preventing the bottom from splitting; and enabling the bolt 15 to be drawn up tightly without buckling or splitting the bottom 1. Preferably, screw bolts will be used at 15 and 16 so that an ordinary screw driver and a small wrench may be employed in fastening together the parts, tightening them, or disconnecting them.

The screw bolt 16, by its connection to the back 3, in conjunction with screw bolt 15, provides a very strong connection between the handle and the shovel and also braces the back 3 so that a very heavy load of snow may be carried without straining the bottom 1, sides 2 or back 3.

The bottom of the shoe 7, in conjunction with the wear plate 18 and the nut 19, very materially relieves the bottom 1 from abrasion when the shovel is used in the ordinary manner.

What I claim is:

1. In a snow shovel, the combination with the blade thereof, of a re-inforeing shoe whose ends terminate at the side edges of the blade and whose top is flush with the upper face of the blade and whose bottom underlies the forward edge of the blade and is provided with ears or lugs on its underside which are connected to the bottom of the blade.

2. In a snow shovel, the combination with the blade thereof which has its forward edge rabbeted on prising upper and lower parts extending crosswise of the blade which terminate at the side edges of the blade, the upper part of said shoe lying in said rabbet and having its top flush with the upper surface of the blade, said shoe having its lower part underlying the forward edge of the bottom of the blade and provided with ears or lugs lying below the bottom of the blade, and means fastening the ears of said shoe to the underside of the blade.

3. A snow shovel comprising a blade, sides, and a back therefor, a re-inforcing shoe at the forward scraping edge of the blade, a handle whose lower end is seated on the blade and in front of the back, an upright bolt extending through the blade and through the 7 forward part of the handle, and a forwardly and rearwardly extending belt which passes from rear to front through the back and through that part of the handle which is located in front of the bac its upper face, of a shoe com- 4. A snow shovel provided with a re-inforcing shoe at its scraping edge, said shoe underlying and projecting below the bottom of the blade, a re-inforcing wear plate attached to the bottom of the blade rearwardly of said shoe and projecting below said bot tom, said underlying part of the shoe and the wear plate being adapted to jointly assume the wear on the bottom of the shovel.

5. A snow shovel having a back and provided with a re-inforcing shoe at its scraping edge, said shoe underlying and projecting below the bottom of the blade, a re-inforcing wear plate attached to the bottom of the blade rearwardly of said shoe and projecting below said bottom, said underlying part of the shoe and the wear plate being adapted to jointly assume the wear on the bottom of the shovel, a handle which overlies the blade in front of the back thereof, a bolt extending throu h the wear plate, the shovel bottom and tie forward part of the handle, and another belt which passes through the back of the shovel and through the handle rearwardly of the first-named bolt.

In testimony whereof I aflix my signature.

MAURICE ANDERSON.
