Definitions

  • a brush finishing device in the form of an abrasive drum having a sinuous exterior, generally of a sign wave configuration, the drum preferably being utilized by two such drums being tandem mounted in ofiset relationship with respect to one another on opposite sides of a path of brush travel, the two drums being driven in opposite directions relative to each other to toughen the bristles of brush fed through the path of brush travel.
  • This invention relates to abrasive devices and more particularly to a novel abrasive drum well suited for finishing bristle-like articles such as brushes and the like.
  • Still another object of this invention is to provide a new and improved abrasive drum for finishing brush bristles having an undulated exterior which causes the brush bristles to progressively fan out and compact as a brush is moved axially of the drum with the free ends of the bristles in engagement with the periphery of the drum.
  • Yet another object of thi s invention is to provide a new and improved brush finishing machine for abrasively finishing substantially all of the free end surfaces of all the bristles of both sides of a brush.
  • FIGURE 1 is a front elevational view of a brush finishing machine utilizing the finishing means of this invention
  • FIGURE 2 is a top plan view of the machine shown in FIGURE 1;
  • FIGURE 3 is a section view taken along the line 33 of FIGURE 1 showing the lateral offset of the tandem mounted abrasive drums with respect to each other and showing a brush moved through a path which is medial with respect to the axes of the drums;
  • FIGURE 4 is a fragmentary sectional view showing the relative position of a brush and first drum shown in FIGURE 3;
  • FIGURE 5 is a fragmentary sectional view similar to 3,416,262 Patented Dec. 17, 1968 FIGURE 4 showing therelative position of a brush and the second drum shown in FIGURE 3;
  • the brush finishing unit 10 illustrated in FIGURES 1 and 2 includes a generally indicated frame 12 having brush finishing accessories 14 mounted on the frame by means 15 which permits vertical and horizontalmovement of the accessories relative to the frame.
  • the accessories are mounted in tandem in the same general horizontal plane and slightly laterally offset with res pect to their longitudinal axes.
  • the accessories 14 are provided for performing a finishing operation on brushes 16, and in particular, upon the bristles 16a held in the brush handle or heel 1611, as they are fed by a conveyor means 18 through the unit 10 past the finishing accessories 14.
  • a driven shaft 20 which is driven by a motor means 21 is provided for supplying power to drive the conveyor means 18 for advancing the brushes through the unit.
  • Each finishing accessory 14 includes a housing 22 having an exahust duct 22a for carrying away abrasive dust and the like.
  • An accessory drive shaft 24 is rotatably mounted within the housing and driven by a motor means 26 through a. pulley and belt means generally indicated 28 shown in dotted outline in FIGURE 1.
  • the abrasive drum 30 of this invention is mounted within the housing on the shaft 24 by a collar and set screw 30a and 32a, respectively.
  • the conveyor means 18 may include two opposed driven bolts 34, each mounted on a conveyor base 36 and defining a brush driving channel between the belts.
  • a housing 38 may be provided for enclosing the belt assemblies.
  • the brushes are advanced by the facial engagement of the opposed faces of the brush heel or handle 16b with the opposed parallel faces of the driven belts to move the brushes longitudinally of the unit or axially with respect to the shafts 24 of the abrasive drum.
  • Each drum 30 comprises a hollow cylinder 40 having end walls 42 spaced slightly inwardly of each end of the cylinder.
  • the end Walls are provided with openings 42a in which the collar 30 is positioned for fixing the drums to the accessory drive shaft 24.
  • Each cylinder has an undulated exterior which consists of annular relieved portions 48 and raised portions 50 formed generally concentrically about the shaft and parallel to each other in planes which are generally perpendicular to the shaft 24.
  • the raised portions all have the same diameter and the relieved portions likewise have the same diameter.
  • the raised and relieved portions are joined by a smooth interconnecting frustoconical section 52 so that, as illustrated in FIGURE 7, a section view through the wall of the cylinder 40 shows a configuration which is similar to the well-known sine wave.
  • the exterior of the cylinder 40 is coated with an abrasive material, preferably a nickel clad tungsten carbide.
  • an abrasive material preferably a nickel clad tungsten carbide.
  • two such drums are mounted as shown in the drawings so that their axes of rotation are positioned on opposite sides of the brush 16 as it is fed by the conveying means through the brush finishing machine. Furthermore, one of the drums is rotated in a clockwise direction as indicated by arrow C in FIGURES 5 and 6, and the other drum is driven in a counterclockwise direction as indicated by the arrow B in FIGURES 3 and 4.
  • each brush will first contact the periphery of one of the laterally offset drums which will cause the brush bristles to be flipped or fanned to one side as shown in FIGURES 3 and 4 where the drum is driven in a counterclockwise direction indicated by arrow B.
  • the brush As the brush is further advanced in the direction indicated by the arrow A, it will travel beyond the first laterally ofiset drum and con tact the second later-ally offset drum which is rotated in the opposite direction as indicated by arrow C. This will cause the bristles to be flipped to the other side of the path of brush travel.
  • a brush such as a paint brush
  • a finish ing operation wherein the entire peripheral extent of the free ends of all of the brush bristles, from the innermost to the outermost of such bristles, will be subjected to the finishing action of the drum so that the desired fuzzy or velvet-like feel and appearance can be imparted to these bristle ends to provide paint brushes of improved paint holding and paint applicating qualities.
  • a brush finishing machine comprising: a frame; conveyor means on said frame for carrying brushes through a brush finishing path; first and second rotatably driven drums on said frame in tandem relation to each other, both drums being positioned so that portions of the peripheries of each drum intersects the brush finishing path to engage brush bristles of a brush carried therethrough, each of said drums having an uninterrupted sinuous exterior coated with an abrasive material; one of said drums mounted for rotation on an axis which is laterally otfset to one side of the brush finishing path; the other of said drums mounted for rotation on an axis which is laterially offset to the other side of the brush finishing path.
  • a brush finishing machine comprising: a frame; conveyor means on said frame for carrying brushes through a brush finishing path; a rotatably driven drum on said frame, said drum being positioned so that portions of the periphery of said drum intersect the brush finishing path to engage brush bristles of a brush carried therethrough, said drum having an uninterrupted sinuous abrasive exterior with arcuate raised and arcuate relieved portions; said drum being mounted on the frame for rotation on an axis which is laterally offset to one side of the brush finishing path.
