Definitions
- the present invention relates to a polishing or grinding wheel of the type where a cylindrical or disc-shaped body is provided for being secured to a rotatable shaft, the cylindrical surface of said body providing support for convenient polishing or grinding material, for instance steel wool.
- steel Wool or the like material has had extensive use for grinding or polishing of metal, wood, or other materials. Such grinding or polishing work conventionally is carried out manually, the steel wool being used in loose bunches. Further it has been proposed'to secure agglomerations of polishing or grindin'g filaments to the circumference of disc elements, which are then' assembled to form a polishing or grinding drum. Polishing segments made from textile material have also beenpropo'sedifor the building-up of such polishing members. In the practice of the prior art it was very diflicult to secure polishing or grinding material in such a Way that it may be easily replaced when worn down, without at the same time'aifecting its performance during the polishing or grindin'gwork.
- the base, to which the polishingor grinding material is secured, must not protrude. through the material, to prevent damage to the polished or' ground object. This however is not avoided by devicesl'of prior art after a 'certainwear and tear. It h'as'als'o been proposed previously to polish or grind profiled bodies, for which it is difficult to arrange the fila-' ments in the desired direction inrela'tion to the polishing or grinding. In such an instance displacement of the filaments must be avoided, sothat the steel wool does not get lumpy or not'in other Ways-displaced in the surface of the polishing or grinding disc or wheel.
- Theflinvention has for its object to provide a polishing or'grinding'wheel, which-is not encumbered with drawbacksof thep'rior art; Anotherobject of theinvention is to provide a polishing orgrindingwheel which'is simple and cheap to produce and easy to adaptiil desired width and diameter and further may beused worn down'considerably more than previously has Been possible, whereby'it is also trafficn in'us'e'.
- An object of the invention is to employ for mechanical grinding and similar operations steel wool, given the form of a braided, woven, or twisted band, placed around the circumference of a rotating cylinder or other suitable support.
- Fig. 1 is a perspective view of a polishing or grinding wheel according to the invention.
- Fig. 2 shows the device according to Fig. 1, in crosssection.
- Fig. 3 is an elevation of a single disc element, bights of of a band of desired material, for instance steel wool, partly being applied.
- Fig. 4 is a modification of Fig. 3.
- Fig. 5 shows a single element in cross section and arranged according to a further modification.
- Fig. 6 shows a further modification of the single elements of the polishing or grinding wheel partly in elevation and partly in section.
- each disc is provided along the edge with means for securing substantially radially extending bights of a filament band or the like of the material to be used, for instance steel wool.
- Simple and cheap single elements are provided thereby, for instance in the form of a pasteboard disc having a steel wool braided circumference.
- the bights or loops of steel wool are secured substantially radially they will have a favourable direction in relation to the polishing or grinding work, and as they protrude relatively far from the edge of the pasteboard disc, they may be worn down until the edge of the disc is visible, at which time substantially all the steel wool secured to the disc will be consumed in the polishing or grinding work.
- Such a single element also may be used alone, in which case it can be secured to a rotating shaft supported by compressing discs or the like.
- the single elements are, however, preferably intended to be used as a part of an assembled o'r built-up polishing drum or wheel, the desired number of such elements being placed side by side, if desired,
- FIGs. 1 and 2 such an assembledpolishin'g' or grind? ing Wheel or drum 1 is shown secured to a shaft 2 and held together axially by means of a pair of compressing discs 3, which can be pressed toward each other and secured by conventional means such as, for instance, nuts;
- Fig. 2 is shown an assembly of seven single elements 4, the circumference of which is provided with steel wool 5, liner discs 6 and compressing discs .3, 3', formin'g'a polishing or grinding wheel or drum 1.
- Fig. 3 shows an example of the method of securing" the polishing or grinding material to the edge of a ingle element.
- the element 4 is provided with a series of holes 7.
- a continuously extending band 8 of polishing or grinding material, as for instance steel wool filaments, is secured along the edge of the disc 4, by interlacing the bights 9, 9 of the band 8 through the holes 7, alternately from each side so that the bights 9 extend between two adjoining holes on one side andthe bights simil-arlyon thej other side in the Way clearly shown in the figure.
- the band 8 is fastenedto the circumference'of the disc 4' and reliably secured in a very simple wa Fig. 4 snows-a somewhat modified-embodimenterthe invention, where the disc 4 is made from a material such as pasteboard or plastic, so that the band 8 can be arranged in bights 10 secured to the disc 4 by means of stapling 11.
- Fig. 5 a disc 4 similar to that of Fig. 3 but provided with side covering discs 14, 14'. These covering discs have peripheral parts with the object to keep the steel wool 9" in place in relation to the holes after the outer bights of the filament band are worn away, so that they will protrude radially as brushes 9", as seen in the drawing.
- Fig. 6 shows the disc 4" provided with pressed-out parts or hooks 16, around the outer edge of the disc 4", for the fastening of the bights 10 of the band 8'.
- the disc 4" is shown provided with side covering discs 15 preferable for this type of attachment of the band.
- a number of polishing or grinding elements having different diameters may be assembled in order to provide for different desired profiles of the assembled polishing or grinding drum or wheel.
- grinding or polishing surfaces of convex and/or concave shapes may be obtained to produce wavy surfaces.
- Such assembled polishing or grinding drums or wheels can be used for instance for grinding or polishing of irregularly shaped surfaces of portions of furniture.
- abradm the polishing, grinding and glazing, each involving the idea of a frictional contact for relative degrees of abrading
- a circular disc In an abrading wheel, a circular disc, a single continuous band of metallic wool filaments, and means securing said band to the peripheral surface of said disc to form a continuous series of loops, each said loop extending radially outwardly of the circumferential edge of said disc.
- a circular disc In an abrading wheel, a circular disc, a single continuous band of metallic wool fibers secured to said disc at equally-spaced points adjacent and about the periphery thereof, said band between contiguous points being in the form of a loop extending radially outwardly of the circumferential edge of said disc. 7 3.
