Abstract

A coating machine comprising a tank for holding a quantity of coating material, a conduit connected to the tank for conveying coating material from the tank and dispensing coating material onto a surface and a coating material spreading arrangement extending from the tank and the conduit for spreading coating material, the arrangement including a first blade, a brush, a middle blade, a pair of end blades forming a box with the first and middle blades and a finish blade of sufficient width to remove the tracks of the end blades.

Claims

1. A coating apparatus comprising:

a) a support frame;

b) a tank for containing coating material mounted on said support frame, said tank having a conduit connected thereto for dispensing coating material onto a surface;

c) a coating material spreading applicator mounted on said support frame for applying coating material, said applicator including a first blade and a finish blade and a pair of end blades; and

d) whereby said end blades are mounted to said support frame independently of said first blade and said finish blade.

2. The coating apparatus as set forth in claim 1, wherein:

a) said frame is supported upon wheels and includes a handle for facilitating manual propulsion of said frame.

3. The coating apparatus as set forth in claim 1, wherein:

a) said end blades are detachably connected to said support frame.

4. The coating apparatus as set forth in claim 1, wherein:

a) said frame is supported upon casters and includes a handle for facilitating manual propulsion of said frame.

5. The coating apparatus as set forth in claim 1, wherein:

a) each of said end blades includes a vertically extending portion located between an upper flange and a lower flange, said upper flange being adapted for connection to said frame and said lower flange adapted for retaining a runner.

6. The coating apparatus as set forth in claim 5, wherein:

a) said runner is formed of a rubber insert.

7. The coating apparatus as set forth in claim 1, wherein:

a) said spreading applicator further includes a brush and a middle blade.

8. The coating apparatus as set forth in claim 1, wherein:

a) said first blade is formed of 60 durometer rubber.

9. The coating apparatus as set forth in claim 7, wherein:

a) said middle blade is formed of 50 durometer rubber.

10. The coating apparatus as set forth in claim 1, wherein:

a) said finish blade is formed of 35 durometer gum rubber.
