Abstract

A heavy duty scraper tool comprises:

(a) two steel plates extending in parallel relation to clamp a steel scraper blade therebetween, so that the blade projects forwardly from between the plates to present a forward scraping edge,

(b) adjustable fasteners extending between the plates to clamp them toward and against said blade and so that the fasteners can be loosened to permit blade removal and replacement,

(c) a connection integral with one plate and forming a pipe thread,

(d) an elongated metal pipe having a thread at one end thereof and threadably joined to said connection to extend rearwardly relative to said plates,

(e) and a handle carried by the pipe, remotely rearwardly from the plates.

Claims

1. In a heavy duty scraper tool, having a steel blade, the combination comprising

(a) two steel plates extending in parallel relation to clamp said scraper blade therebetween, so that the blade projects forwardly from between the plates to present a forward scraping edge, the blade being rectangular and having forward scraping edge and two laterally spaced forwardly extending edges, the blade having the form of a flat metal sheet,

(b) adjustable fasteners including two pairs of bolts extending through four holes in the plates between and through the plates to clamp them toward and against said blade and so that the fasteners can be loosened to permit blade removal and replacement, the bolts everywhere spaced from the blade, one pair of bolts located proximate one blade lateral edge, and the other pair of bolts located proximate the other blade lateral edge, the two plates having combined thickness substantially greater than the blade thickness,

(c) a connection integral with one plate and forming a pipe thread,

(d) an elongated metal pipe having a thread at one end thereof and threadably joined to said connection to extend rearwardly relative to said plates, said one end of the pipe located proximate said one plate, said pipe extending substantially parallel to the blade,

(e) and a handle carried by the pipe, remotely rearwardly from the plates.

2. The combination of claim 1 wherein said pipe includes multiple sections which have screw threaded means to interconnect same, whereby the operable length of the pipe is adjustable, to add weight to the weight of the plates and blade for enhancing the scraping power of the tool.

3. The combination of claim 1 wherein the pipe has wall thickness of about 1/16 to 3/16 inch, and the pipe diameter is between 158 to 11/4 inches.

4. The combination of claim 1 wherein said handle comprises a pipe tee attached to the end of the pipe remote from the plates, and auxiliary pipe sections attached to the tee and extending sidewardly.

5. The combination of claim 1 wherein said connection comprises a pipe collar welded to one of the plates.

6. The combination of claim 1 wherein the blade and its edge project forwardly from between said plates, and is adjustable forwardly and rearwardly relative to said pairs of fasteners, when the fasteners are loosened.

7. The combination of claim 1 including synthetic resin applied to the blade edge to protect same.

8. The combination of claim 7 including an envelope receiving the blade and its resin protected edge, prior to installation.
