Claims.

This invention relates to a scraper and is more particularly designed for removing ice and snow from the windshields of automobiles, aircraft, etc. The principal object of the invention is the provision of a device which will effectively break up and remove hardened frost and ice from the windshield.

Another object is to combine with theice breaking feature a squeegee which can be used to remove snow and water from the windshield.

Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efiiciency. These will become more apparent fromthe following description.

In the following detailed description'of the invention reference is had to the accompanying drawings which form a part hereof. Like numerals refer to like parts in all views of the drawings and throughout the description.

In the drawings:

Fig. 1 is a perspective view illustrating the device in use for removing snow from a windshield;

Fig. 2 is a similar view illustrating the device in use for removing ice or frost;

Fig. 3 is a face view of .the improved scraper;

Fig. 4 is a longitudinal section therethrough, taken on the line 4-4, Fig. 3;

Fig. 5 is a detail side view illustrating the ice scraping position;

Fig. 6 is a similar view illustrating it in the squeegee position.

Fig. '7 is a detail view of a blade protector for use on the sharpened edge of the scraper; and

Fig. 8 is a fragmentary view of an alternate form of scraping edge.

The invention consists of a fiat metallic plate 10, preferably of stainless steel or similar edgeholding, corrosion-resisting material.

A plurality of pairs of spaced-apart slots I! extend into one extremity of the plate ID to form relatively narrow ice breaking blades l2. Intermediate the ice breaking blades I 2, the edge of the plate is inset to form a plurality of wide scraping edges 13. edges l3 are preferably sharpened. If the blade is of sufficiently thin material, however, this sharpening may be omitted.

A relatively thick rubber pad 14 is secured to one face of the plate I 0 and projects beyond the two sides and one extremity thereof. The rubber pad may be secured to the plate in any desired manner. As illustrated, metallic tongues Both the blades l2 and the [5 are pressed from the plate material and ex- .and loosen the ice.

tend through therubber pad to form hooks for holding the latter in place.

- For removing ice, the sharp edge of the blade is pushed forwardly against the windshield, as shown in Fig. 2. The blades [2 flex ahead of the edges l3, as shown in Fig. 5, and enter beneath The edges l3 then follow to scrape the loosened ice from the windshield.

For removing water and snow, the sides or end of the rubber pad H are used as a'squeegee such as shown in Figs. 1 and 6. To protect the hand while using the rubber portion, a guard I6 is provided. This guard is preferably formed of spring steel so that it will tightly grip the blade after the latter has been forced therein. The steel is bent back upon itself to form a closed U-shape and is preferably provided with a rounded edge II to facilitate the entrance of the blade.

If desired, the extremities of the breaking blades l2 may be widened, as shown at I8, in Fig. 8, to cut wider swaths during the ice breaking operation.

While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent is:

1. A scraper comprising: a flat metallic plate;

aplurality of pairs of relatively close slots extending inwardly from one extremity of the plate; and a relatively narrow projecting blade between the slots of each pair, the edges of the plate intermediate the blades being relatively wide and being cut back from the extremities of the latter.

2. A scraper comprising: a flat metallic plate; a plurality of pairs of relatively close slots extending inwardly from one extremity of the plate; and a relatively narrow projecting blade between the slots of each pair, the edges of the plate intermediate the blades being relatively wide and being cut back from the extremities of thelatter, said blades projecting beyond the latter edge of said plate.

3. A scraper comprising: a fiat metallic plate; a plurality of pairs of slots extending inwardly from one extremity of the plate; and a relatively narrow projecting blade between the slots of each pair, the edge of the plate intermediate the blades being cut back from the extremities of the latter, said blades projecting beyond the latter metallic plate; a scraping edge on said plate; and

a plurality of spaced-apart, relatively narrow, ice

breaking blades projecting forwardly beyond said scraping edge, said blades joining said' plate rearwardly of said scraping edge and lying in the same plane therewith.

5. A windshield ice scraper comprising: a flat metallic plate; a scraping edge on said plate; a plurality of spaced-apart, relatively narrow, ice breaking blades projecting forwardly beyond said scraping edge, said blades joining said plate rearwardly of said scraping edge and lying in the same plane therewith; and widened extremities on said ice breaking blades overlapping the ad'- jacent portions of said scraping edge.
