ICE-SCRAPING TOOL Filed March 20. 1959 INVENTOR. 5/0: Y C. M06AN Arme/ nited S ate Pat nt '0 ICE-SCRAPIN G TOOL Sidney C. Morgan, 20345 Middlebelt, Livonia, Mich. Filed Mar. 20, 1959, Ser. No. 800,686

2 Claims. (Cl. 15-236) This invention relates to an ice-scraping tool, and it particularly relates to an ice-scraping tool adapted to be equally well utilized for either light or heavy ice accumu-' lations on windows, automobile Windshields and the like.

A great many forms of ice-scraper devices have been produced and used heretofore. Some of these prior devices have been better than others and many have been highly successful. However, those scrapers which were heretofore most successful in cleaning light accumulations of ice were not capable of effectively cleaning off heavy accumulations and vice versa. Furthermore, a large number of the former type scrapers were either easily broken, damaged or twisted out of shape or were too expensive for commercial acceptance, because of the initial cost of the materials used and the difficulty of manufacture.

It is one object of the present invention to overcome the above as well as other disadvantages of prior icescrapers by providing an ice-scraping tool which is equally well adapted to clean both light and heavy ice accumulations and which is not easily damaged or misshaped.

Another object of the present invention is to provide an ice-scraping tool of the aforesaid type which is simple in construction, light in weight and easy to use.

Other objects of the present invention are to provide an improved ice-scraping tool, of the character described, that is easily and economically produced, which is sturdy in construction, and which is highly efficient in operation.

With the above and related objects in view, this invention consists in the details of construction and combination of parts, as will be more fully understood from the following description, when read in conjunction with the accompanying drawing in which:

Fig. 1 is a perspective view, partly broken away in section, of an ice-scraping tool embodying the present invention; the tool being shown in use.

Fig. 2 is a view, partly in elevation and .partly in section, taken on line 2-2 of Fig. 1.

Fig. 3 is a sectional View taken on line 3-3 of Fig. 2.

Referring in greater detail to the drawing wherein similar reference characters refer to similar parts, there is shown an ice-scraping tool, generally designated 10, which comprises a handle 12 having a concave neck portion 14. The handle 12 may be constructed of wood, metal, plastic or any other desirable and feasible material.

The upper end of the handle 12, adjacent the neck portion 14, is concavely grooved, as at 16, to snugly receive the bridge portion 18 of a generally U-shaped blade mem-- ber 20. The neck portion 14 is also provided with opposed, V-shaped, flattened portions 22 extending downwardly from the grooved end 16 and having their apex portions, at the lower ends, blend into the main body of the handle 12.

The upper'portion of the handle 12 is further provided 2,946,076 Patented July 26, .1960

2 Y with a threaded central bore extending down from the grooved end 16, this bore being adapted to receive a metal screw 28. The screw 28 is also adapted to extend through a central-.aperturein the bridge portion 18 of blade member 20 as well as through a central aperture in a strip of molding 26.

The strip 26 is constructed with a flat upper surface and a convex lower surface to be snugly embraced within the confines of bridge portion .18. This strip 26 is preferably constructed of aluminum but may, if desired, be made of any other feasible material such as hard wood, plastic, other type metal, etc. The strip 26 functions as a strengthening member as well as a spacing means between the arms' of the blade 20. It is used because if a relatively great pressure is placed on the blade 20, the blade arm portions have a tendency to spring together and will eventually break. The strip 26 holds the blade firmly to the handle and also holds the blade arm portions apart so that they cannot spring together. The aperture in the strip 26 is of a width to snugly re ceive the head of the screw 28 (as shown in Fig. 3) in countersunk position.

The blade 20, as previously indicated, is of generally U-shaped configuration with its bridge member 18 of a size and shape to be snugly received in the grooved end 16 of the handle 12. The blade 20 is, furthermore, preferably constructed of a material that will not scratch glass, such as vinyl plastic, hard rubber, sheet Plexiglas or any other desirable material. terial such as Plexiglas, it is heated and bent into shape. If the blade is made by injection molding, ribs, bosses or similar strengthening means are preferably provided to add strength and save material.

One arm of the blade 20 is provided with an uninterrupted, sharp, beveled edge 30 while the other arm is provided with a beveled edge 32 having a series of preferably evenly spaced, three-sided, beveled grooves 34. The edge 30 is used for frost or light ice accumulation whereas the edge 32 is used for thick ice coatings. The

beveled grooves 34 act somewhat like scoops to breakup:

the thick ice accumulations.

It is to be understood that the size of the blade 20 as well as of the handle 12 may be varied as desired. Such variation of size may include enlarging or decreasing the If made of sheet ma- I size of both the blade andhandle, or changing the size l i of one relative to the other so that a longer or shorter" I handle may be used with the same size blade or a larger or smaller blade may be used with the same size handle.-

Although this invention has been described in considerable detail, such description is intended as being illustrative rather than limiting, since the invention may be variously embodied, and the scope of the invention is to.

be determined as claimed.

Having thus set forth and disclosed the nature of this invention, what is claimed is:

1. An ice-scraping tool comprising an elongated handle having a neckportion, a concave groove defining the end' of said handle adjacent said neck ana a threaded -axial'bore in said handle, said bore intersecting 'saidconcave groove, a generally U-shaped blade member, of subof a screw extending through acentral aperture in said. E

bridge portion'and into saidbore, said bridgeportionf; being seated in said concave groove, and said screw also 7 extending through an aperture in a spacer strip positioned within said bridge portion between said arm portions,

said screw having a head in holding position relative to sharp, knife-edge defining an ice scraping means -pro-,

vided by a beveled, curved surface flaring outwardly from the inner surface of said U-shaped member to its outer surface.

2. The tool of claim 1, one'of said knife-edges being intersected by-a series of spaced apart outwardly flaring grooves of three-sided construction, the three sides of said grooves beingflat and flaring away from each other,
