Definitions
- This invention relates to a scraper for removing calcareous growths, anemones, mussels, sea-weeds or algae, etc. on flat or arched surfaces.
- the invention has for object to provide a scraper which obviates the drawbacks of the scouring disks or scrapers known up to now and which also makes it possible then to loosen calcareous growths with any structure and extent whatsoever from flat or arched surfaces, and thereby letting undamaged the paint coat on the structures being treated.
- the scraper is formed according to the invention by a motor-driven disk with a number radial knives distributed along the circumference thereof, which knives have a structure allowing bending thereof along at least two planes, namely that lengthwise symmetry plane wherein the knife extends and a plane which extends at right angle to said first plane and in parallel relationship with the disk geometrical axis.
- the scraper according to the invention is essentially comprised of a disk 1 whereon a number radial curled knives 2 are secured.
- the knives 2 are cantilever ones, which means that the free end thereof does not bear on some surface of disk 1.
- Other shapes of cantilever knives are shown in figures 7, 8, 9, 10 and in some way 12.
- Cantilever knives have as compared to loop-shaped knives which bear with both ends thereof on disk 1 from the scraper, the very large advantage of bending or deflecting in that location where they engage the surfaces to be cleaned. Such deflection occurs due to the knives tapering towards the free end thereof or having a thickness which is progressively reduced towards the free end. Both these features may naturally be combined.
- Loop-shaped knives are then to be used efficiently but when they have locally a thickness which gets progressively thinner.
- the knife may narrow in the direction of the contact point with the surface to be cleaned, or narrow in an arbitrary location as far as this allows the knife deflecting.
- FIG 2 it is made clear how a disk 3 fitted with flat knives 4 extending outwards along the circumference, is retained by calcareous growths 5.
- the knives 4 do indeed enter to a limited depth the grown mass, but such mass then directly forms an obstacle to disk 3 which can not further enter or at least but with great difficulty, the growths to be scoured.
- the drawback of such scrapers is mostly evident when calcareous growths are being treated.
- Such straight knives 4 unavoidably damage the paint coat on the surfaces to be scoured. This is also a very substantial drawback of scouring disks fitted with said straight-type knives.
- the shells or other calcareous growths, anemones, sea-weeds and algae are treated in accordance with a completely new principle. Due to the curl shape of the knives with a cantilever end (figure 3), the disk edge 6 never does engage the growths or deposits to be removed. Same are continuously attacked by the radially-arranged curled knives, in such as a way that said growths and deposits continuously break-off and may be removed from the surface to be scoured without the scraper being hampered or slowed-down in the movement thereof as shown by arrow 7 (figure 3).
- said knives When the knives are moved over an obstacle such as a welding seam 9 for example, said knives also bend as well in the lengthwise symmetry plane of the knife as in a plane which lies at right angle thereto and extends in parallel relationship with the geometrical axis of disk 1.
- the reference numeral 10 shows a surface to be cleaned where a welding seam 9 is present, or where growths such as as mussels 12 occur. That direction the knives 2 move along, is shown by arrow 11.
- curled covers a series possible embodiment shapes figures 1, 3 and 7 to 13 pertain to.
- teeth are self-sharpening. Due to the shape and section thereof, the knives and the disk they are secured on, may in many cases be cast as a single part. This is notably true when such components are made from a synthetic material. Many embodiments allow making the disk with the teeth by injection-moulding or casting.
