Definitions
- This invention relates to blades for carpet and tile floor stripping machines and more particularly to an angled carbide tipped blade.
- Another type of floor stripping machine has a blade resting on the floor like a plow with a pushing force applied behind the blade parallel to the floor. However it is difficult to keep the blade flat on the floor and the blade will ride up over the material to be stripped.
- a further type of stripping machine representing the closest prior art, is described in US 4,860,450 which can strip walls and floor coverings. It comprises a casing, including an electric motor attached to a gearbox, and a circular disc blade having one or more cutting edges at its periphery. To increase longevity and wear of the blade, the cutting edge may be faced with carbide.
- the blade is generally concave in profile and has sufficient flexibility to allow the blade to flex when pressed against the surface to be stripped.
- the machine relies upon pressure exerted by the operator in use to present the blade to the surface at the right angle.
- an angled stripper blade has a shoe portion for riding on the floor and having the weight of the machine on it for engaging the floor.
- a blade on the from portion of the shoe is held parallel to the floor for skiving the ceramic tiles, carpet, tile, adhesive or other material from the floor surface.
- the blade angle relative to the floor is optimized for stripping the floor.
- the carbide tip on the shoe is stronger and last longer than a metal blade and can be changed easily when the tip gets dull.
- the figure is a side view of the angled blade shank.
- the figure shows a blade 16 having a carbide insert 10 for engaging ceramic tiles or other material to be removed from a floor.
- the blade 16 has a flat bottom portion 12 for riding on the floor and holding the blade parallel to the surface of the floor.
- the head of the blade 15 is attached to the top of blade 16 and has a shank 18 attached at an angle which is on the order of 22 degrees from the floor such that the weight of the stripper machine can be used to push down on the blade 12 and keep the blade on the floor such that the carbide insert 10 can skive the unwanted material from the floor.
- the shank 18 has an aperture 20 for attaching the shank to the stripper machine such that the weight of the machine rests on the surface 12 of blade 16.
- the angle of the shank in the figure is 22 degrees which is favorable for extending the blade out in front of the machine while placing the weight of the stripper machine on the back portion of the blade 16.
- the front portion of the blade 16 with the carbide insert 10 has the weight of the machine behind it for pushing on the material to be removed.
- the carbide insert 10 has a tip angled at 45 degrees which has been found to be an angle which is efficient for skiving material from floors.
- the blade angle above the insert is 20 degrees to allow the material scraped from the floor to be lifted up easily.
- the blade 16 can be of any width. The narrower the blade width the easier it is to push along the floor to skive material therefrom but then more passes need to be made to remove all the material from the floor.
- the carbide insert is shown with a cutting angle of 45 degrees other angles may be used depending on the type of material to be removed from the floor. Similarly the 20 degree angle on the top of the blade 16 can be changed to fit the job to be accomplished.
- the shank 18 angle of 22 degrees can also be varied depending on the design and weight of the stripper machine and the flooring to be stripped.
- the shank angle lies between 5 degrees and 45 degrees.
- the shank angle lies in an optimum range between about 17 degrees and 22 degrees.
