Ice scraper having non-rotary tools with shielded cutting inserts

A vehicle including an ice-scraping mechanism adapted to scrape ice from a roadway as the vehicle travels in a forward direction, the ice-scraping mechanism comprising:

• a tool carrier mounted on the vehicle;
• and
• a plurality of ice-scraping tools mounted on the tool carrier and depending downwardly therefrom, each tool being non-rotatable relative to the tool carrier and including:
• a shank mounting the tool to the tool carrier, the shank being inclined in an upward and forward direction, and
• a cutting head depending downwardly from the shank and including a forwardly facing rake face having a cutting edge extending along a lower end thereof, the rake face inclined upwardly and forwardly from the cutting edge to define a positive rake angle.

An ice-scraping tool comprising:

• a shank adapted to mount the tool in a carrier and defining a longitudinal axis;
• and
• a cutting head disposed at a lower end of the shank, the cutting head including a rake face, a cutting edge extending along a lower end of the rake face, and a clearance face extending from the cutting edge in a direction extending away from the rake face and inclined upwardly toward the shank, the cutting head formed by a main body and a hard insert mounted in the main body;
• the main body including a forwardly facing front surface defining the rake face and a bottom surface extending rearwardly therefrom and defining the clearance face,
• the insert including a forwardly facing front surface oriented parallel to, and spaced from, the front surface of the main body, the insert further including a bottom surface extending rearwardly from the front surface of the insert, the insert formed of a harder material than that of the main body to be more wear resistant than the main body;
• a portion of the main body situated in front of the insert and extending farther downwardly than the insert, and such portion of the main body being wearable relative to the insert during an initial wear-in period of the tool, whereby the front and bottom surfaces of the main body initially form the rake face and clearance face, respectively, of the tool, and after the wear-in period the front and bottom surfaces of the insert form the rake face and the clearance face, respectively.
