Definitions

  • the present invention relates to waxing machines, and, more particularly, concerns the protective rubber strip around waxing machines.
  • the said distance is adjusted small from the Very start, with increasing wear of the brushes the time is fast approaching at which the lower edge o-f the protective rubber strip will drag along the oor and will leave marks.
  • Waxing machines of the type involved are known in which the protective rubber strip may be adjusted as to its distance from the floor in order at least to a certain extent to counter the above-mentioned defects.
  • These heretofore known devices are, however, rather difiicult for an unskilled person to adjust in such a way that the protective rubber strip will assume the proper position as to height.
  • One of the factors which affect the easy adjustability of the rubber strip is the high friction between the elastic material of the rubber strip and the respective adjacent surface of the machine.
  • a certain friction between said machine surface and the rubber strip is necessary in order to prevent an unintentional self-adjustment of the rubber strip.
  • FIGURE l illustrates a disc waxing machine partly in view and partly in section, which is provided with a protective lstrip adjusting arrangement according to the present invention
  • FlGURE 2 illustrates on a somewhat larger scale than FIGURE l that portion thereof which is encircled by a dot-dash line;
  • FIGURE 3 is a section taken along the line III- ill of FlGURE 2;
  • FIGURE 4 shows the same section as is illustrated in FiGURE 3 'out on a considerably larger scale than the latter;
  • FIGURE 5 represents a partial section through a modiiied guiding and locking device for the protective rubber strip
  • FGURE 6 illustrates partly in view and partly in section a portion of a modified lower housing section as seen in the direction of ⁇ the arrow D of FGURE 5 while the protective rubber strip is removed;
  • FGURE 7 is a developed view of the exterior of the housing of the FlGURES 5 and 6 modification.
  • the arrangement according to the present invention is characterized primarily in that the lower marginal portion of the housing of the waxer is provided with holding means by which the adjustable protective rubber ring is held at the respective desired height, while insert means, preferably steel band insert means, are provided for irnparting upon the rubber ring a certain stiffness for preventing any unintentional distortion of the circumference of the protective strip in axial direction of ythe housing.
  • the said holding means are formed by balls which are held in cages connected to the inside of the protective ring, in such a way that they protrude in a resilient manner and will, during the displacement of the protective ring, simultaneously serve as sliding aid.
  • These ball cages may be formed, for instance, by an annular sheet metal part provided with passages of a smaller diameter than the diameter of the respective balls.
  • Locking springs are provided for pressing the balls into depressions in the housing wall.
  • the said depressions may consist, for instance, of grooves along the lower marginal housing portion.
  • the protective strip may be connected to the housing of the waxing machine by means of one or more screw bolts which extend through bores in the protective ring and adjustably extend through -slots in the lower marginal portion of the machine housing.
  • the lsaid locking bolts are spring-biased by a leaf spring for urging the balls into their respective recesses.
  • a plurality of locking means is provided with the recesses offset with regard to each other in conformity with guiding slots uniformly distributed over the circumference of the housing of the waxer.
  • the waxing machine shown therein comprises a housing 1 adapted to be handled in a manner known per se by means' of a guiding bar 3.
  • the waxing machine is furthermore, in a manner known per se, provided with brushes 4 for waxing the floor 5, said brushes being adapted to be rotated by means of an electric motor (not shown) which is arranged in the interior of housing 1.
  • the housing 1 may contain a suction blower for drawing air into the machine along the arrow A to such an extent that the air suction at a corresponding high speed will be able to draw in dust particles within the gap a.
  • the drawn-in air and dust are, in a manner known per se, conveyed into a lilter sack 6 serving as dust-bag.
  • the lower cylindrical portion 7 of the waxing machine housing is provided with substantially evenly spaced horizontal grooves 8.
  • a protective rubber ring or strip 9 reinforced by a steel band 26 firmly engages the cylindrical portion 7 of the waxing machine.
  • the said rubber strip 9 is in a manner known per se designed as a closed ring or as an extruded strip fused at its ends to a closed ring in any suitable manner.
  • the housing of the waxer is designated with the reference numeral 1.
  • the chamber 16 confined by said housing 1 is connected with a suction passage (not shown) of a blower.
  • said chamber 16 also houses the rotating brushcarrying discs 18 which are driven by the driving disc 17.
  • the brushes are adapted in the usual manner to engage the lloor 5 while simultaneously an air suction is created in the direction of the arrow A.
  • the rubber ring 9' together with the floor 5 connes a gap a. This gap decreases with increasing wear of the brushes 4.
  • the circumferential marginal portion 19 of housing 1 is at least at one, preferably at a plurality of locations, provided with cutouts or cutout sections 2u along a spiral line. These cutouts are shown developed in FIGURE 7. It is in these cutouts or cutout sections that bolts 22 are guided by means of spacer bushings 21.
  • the bolts 22 are by means of a Washer and nut secured against tilting and dropping out.
  • the said bolts have a head 22a of a larger diameter than the shank of the bolt and the diameter of bushing 21.
  • the said bolt head 22 is located in a corresponding circular cutout 23 of the protective rubber ring 9.
  • Another purpose of the steel band 26 consists 4in improving the sliding properties of the protective strip 9 on housing portion 19 and also in preventing the balls 25 from dropping out during the installation on the waxing machine. Still another purpose of the steel band 26 consists in preventing an axial distortion of the rubber ring along the circumferential portion thereof.
  • the leaf-spring 24 brings about a locking of the .balls 25 in recesses 27 on the housing.
  • the arrow B in FIG. 6 indicates the adjusting possibility of the elements 9', 21, 22, 24 and 25 from the position shown in PIG. 6. As will be evident therefrom, such an adjustment automatically brings about an adjustment as to height of the rubber ring 9' in the direction of the arrow C, which in turn results in reducing the gap a.
  • a plurality of slots 20 is uniformly distributed over the circumference of 'the housing, as shown in FIGURE 7.
  • a plurality of possibilities of locating locking means 27, also shown in FIG- URE 7 may be provided in conformity with the respective individual recesses 2li.
  • the locking possibilities for a second passage 20 may be so arranged that alternately the recesses of a different row become effective so that a finer adjustment will be possible.
  • One of the bolts 22 simultaneously serves for holding the ends of the steel band 26 in abutting engagement.
  • the upper marginal portion 9a of the rubber ring 9 will be held in rm engagement with the housing 1' to the desired extent by the elasticity of the rubber ring.
  • a housing having its lower peripheral portion provided with spaced circumferentially inclined slot means, an annular rubber member arranged on the lower peripheral portion of said housing and being provided with holes 'therethrough registering with said slot means, said annular rubber member having its inner peripheral surface provided with annular recess means thereby reducing the area of engagement of said rubber member with said housing, circumferentially spaced screw bolt means extending through said passage means and said holes and operable to permit circumferential and simultaneous axial adjustment of said annular rubber member relative to said housing while retaining said rubber member on said housing, and detent means provided between said rubber member and said housing for releasably holding said rubber member in predetermined adjusted positions relative to said housing.
  • said detent means comprises spaced recesses in said housing and also comprises ball means carried by the rubber member resiliently urged toward said recesses.
  • a housing having its lower peripheral portion provided with spaced circumferentially inclined slot means, an annular rubber member arranged on the lower peripheral portion of said housing and being provided with passage holes therethrough registering with said slot means, said annular member having its inner peripheral surface provided with annular recess means thereby reducing the area of engagement of said rubber member with said housing, the outer peripheral housing surface adjacent said recess means also being provided with space depressions, screw bolt means eX- tending through said holes and said slot means and operable to permit circumferential and simultaneous axial adjustment of said annular rubber member relative to said housing and to support said rubber member on said housing, ball means arranged within said recess means, and leaf spring means interposed between said rubber member and said housing and yieldably engaging said ball means for urging the same in a radial inward direction With regard to said housing to cause said ball means to engage said depressions.
  • a housing having its lower peripheral portion provided With spaced circumferentially inclined slot means, an annular rubber member arranged on the lower peripheral portion of said housing and being provided with holes therethrough registering with said slot means, said annular rubber member having its inner peripheral surface provided with annular recess means thereby reducing the area of engagement of said rubber member with said housing, screw bolt means provided with a head and extending through said holes and said slot means and operable to permit circumferential and simultaneous axial adjustment of said annular rubber member relative to said housing and to support said rubber member on said housing, said heads of the bolt means being in said holes, circular sheet metal means interposed between the heads of said screw bolt means and the outer peripheral surface of said housing and reinforcing said rubber member against distortion in axial direction, and detent means provided between said rubber member and said housing for releasably holding said rubber member in predetermined adjusted positions relative t0 said housing.
