Abstract

In an asbestos scraping assembly, the arm of an operator is confortably cradled in a scraper extension bracket so as to apply greater force to a scraper blade with less effort by the operator than is required of a hand-held scraper blade. The hand of the operator holds a bar of the scraper extension bracket so as to position the area of contact of the scraper blade cutting edge with the surface from which asbestos is to be removed.

Claims

1. A scraper assembly comprising:

a scraper blade for scraping a surface, said scraper blade including a first portion and a second portion,

a support bracket extending longitudinally in a plane, said support bracket having two ends,

means for mounting said first portion of said scraper blade on one end of said support bracket, said first portion extending in said plane of said support bracket, said second portion extending at an angle to said first portion, and

the other end of said support bracket including means for engaging and being supported by the forearm of an operator so that upon forward motion of the arm of the operator at an angle to the surface being scraped, said second portion contacts and scrapes the surface.

2. A scraper assembly as in claim 1, wherein said support bracket includes a hand grip bar and at least one elongated member, said hand grip bar being mounted on said elongated member and extending transverse to said elongated member.

3. A scraper assembly as in claim 2, wherein said scraper blade means is rotatably mounted on said support bracket.

4. A scraper assembly as in claim 2, wherein said hand grip bar and said means for engaging and being supported by the forearm of an operator are removably mounted on said at least one elongated member.

5. A scraper assembly as in claim 2, wherein said means for engaging and being supported by the forearm of an operator is an annular ring through which the hand and forearm of the operator are inserted.

6. A scraper assembly as in claim 2, wherein said means for engaging and being supported by the forearm of an operator is the crosspiece of a U-shaped member, the legs of which form said at least one elongated member.

7. A scraper assembly as in claim 2, wherein said means for engaging and being supported by the forearm of an operator is a U-shaped cuff.

8. A scraper assembly for scraping an asbestos-containing covering of a surface, said scraper assembly comprising:

a scraper blade including a first portion and a second portion,

a support bracket extending longitudinally in a plane, said support bracket having two ends,

mounting means for mounting said first portion of said scraper blade on one end of said support bracket, said first portion extending in said plane of said support bracket and said second portion extending at an angle to said first portion, said support bracket including grip means for gripping of the support bracket by the hand of an operator and support means located at the other end of said bracket from said scraper blade for engaging and being supported by the forearm of an operator so that upon forward motion of the arm of the operator at an angle to the surface being scraped, said second portion contacts and scrapes the surface.

9. A scraper blade assembly as in claim 8, wherein said grip means and said support means are longitudinally spaced from each other.

10. A scraper blade assembly as in claim 8, wherein said grip means and said support means are removably mounted on said support bracket for removal and relocation to an opposite side of said support bracket.

11. A scraper blade assembly as in claim 8, wherein said support bracket includes parallel members interconnected by a curved crosspiece forming said support means.

12. A scraper blade assembly as in claim 8, wherein said support bracket includes parallel member interconnected by an annular ring forming said support means.

13. A scraper blade assembly as in claim 8, wherein said scraper blade is rotatably mounted on said support bracket.

14. A scraper assembly comprising:

scraper blade means for scraping a surface,

a support bracket having two ends,

means for mounting said scraper blade means on one end of said support bracket, and

the other end of said support bracket including means for engaging and being supported by the forearm of an operator, said support bracket including a hand grip bar and at least one elongated member, said hand grip bar being mounted on said elongated member and extending transverse to said elongated member, said scraper blade means being rotatably mounted on said support bracket.

15. A scraper assembly as in claim 14, wherein said means for engaging and being supported by the forearm of an operator is an annular ring through which the hand and forearm of the operator are inserted.

16. A scraper assembly as in claim 14, wherein said means for engaging and being supported by the forearm of an operator is the crosspiece of a U-shaped member, the legs of which form said at least one elongated member.

17. A scraper assembly as in claim 14, wherein said scraper blade means includes a scraper blade, a portion of which is bent at an angle to another portion of said scraper blade means.

18. A scraper assembly for scraping an asbestos-containing covering of a surface, said scraper assembly comprising:

a scraper blade,

a support bracket having two ends, and

mounting means for mounting said scraper blade on one end of said support bracket, said support bracket including grip means for gripping of the support bracket by the hand of an operator and support means located at the other end of said bracket from said scraper blade for engaging and being supported by the forearm of an operator,

said scraper blade being rotatably mounted on said one end of said support bracket.

19. A scraper blade assembly as in claim 18, wherein said grip means and said support means are longitudinally spaced from each other.

20. A scraper blade assembly as in claim 18, wherein said scraper blade includes a portion bent at an angle to another portion of said scraper blade.
