Definitions

  • Power driven rotary brushes may utilize a wide variety of brush fill material including wire bristles, Tampico fiber, plastic bristles such as nylon, horsehair, and plastic coated wire or glass fiber filaments as disclosed in Peterson Patent 2,682,734, for example.
  • wire bristles Tampico fiber
  • plastic bristles such as nylon, horsehair, and plastic coated wire or glass fiber filaments as disclosed in Peterson Patent 2,682,734, for example.
  • wire or plastic filaments As the power brushing art has developed, there has arisen an increasing demand for rotary brushes which are true precision tools adapted to be driven at high speeds and having carefully trimmed and often ground brush faces adapted to produce specified predetermined etfects upon the work.
  • wire or plastic filaments as the brush bristle material, it has been conventional to crimp the filaments for a variety of reasons including the damping effect thereby achieved due to the interengagernent of the filaments with one another at intervals along their length.
  • Crimping of the brush material also has certain disadvantages.
  • power driven rotary brushes having crimped brush bristle material par ticularly wheel brushes
  • some of the bristles tend to lengthen under the action of centrifugal force and as a result of their frictional engagement with the work, soon producing a relatively uneven brush face so that other of the bristles are prevented from engaging the work surface to the same degree or even at all.
  • the carefully trimmed and often ground brush face loses its precision contour and the action of the brush on the work becomes correspondingly irregular. It may accordingly become necessary, for precision work, to regrind the brush face.
  • a further object is to provide straight brush bristle material and brushes utilizing the same which will not have the disadvantages encountered in the past, such as long fracture in use, but will instead have the characteristics previously obtained by crimping as well as a new constancy and precision of brushing face.
  • Another object is to provide a power driven rotary brush utilizing straight hard brush bristle material treated in a manner effective properly to space and control such ICC bristles to prevent undue compacting or knifing of the brush face and to assure equal frequency of tip contacts per unit length of face despite surface projections which ordinarily tend to part the fill of conventional brushes so that it does not contact the portions of the work most needing such contact.
  • Still another object of this invention is to provide such brush in which the interaction of the brush bristle material is self-regulated to control the degree and manner of flexing in use.
  • Yet another object is to provide such a brush in which the brush bristle material is resiliently but relatively firmly supported adjacent the base in a manner to assist in maintaining the desired spacing of the bristles and effectively to avoid stress concentration and so improve fatigue life, with such spacing being similarly controlled in the outer portions thereof by individual plastic coatings thereon.
  • FIG. 2 is a side view of an individual novel brush bristle in accordance with this invention, on an enlarged scale;
  • FIG. 3 is a transverse cross-section taken on the line 3-3 on FIG. 2;
  • FIG. 4 is a transverse cross-section taken on the line 4-4 on FIG. 2;
  • FIG. 6 is an end view of a rotary brush utilizing the novel brush material of this invention, the inner end portions of the same being embedded in an elastomeric matrix in the region adjoining the central hub;
  • FIG. '7 is an end view of a modified brushing tool in which such novel brush bristle material is embedded in or encapsulated in a body of elastomeric material extending substantially to the outer working ends of the bristles;
  • FIG. 8 is a side view, partly in section, showing a unitary brush bristle having enlarged portions spaced longitudinally thereof.
  • the brush there illustrated comprises a central annular channelform back or hub I having secured therein generally radially outwardly extending brush bristle material 2.
  • the particular form of hub or back and the mode of securing the brush material therein are not per se a part of the present invention, and reference may be had, for example, to Peterson Patent 2,303,386, Whittle Patent 2,228,337, and Peterson Patent 2,757,400 for typical suitable brush assemblies.
  • the invention is equally adapted for employment in the manufacture of end brushes as shown, for example, in Benyak Patent 2,449,158, wire stern brushes as shown in Peterson Patent 2,895,155, roller brushes and cluster brushes as shown in Peterson Patent 2,682,734, cup brushes, and many others.
  • the brush bristle material may comprise any suitable brush bristles modified in accordance with the present invention but will ordinarily preferably comprise hard wire, especially steel wire having a Knoop hardness of at least 600.
  • the Knoop hardness test is a US. Bureau of Standards test and is particularly suited to measure the hardness of fine filaments. in some cases, the filaments may desirably have a Knoop hardness in excess of 700 and even in excess of 800.
  • Stainless steel brush bristles are greatly improved and their life much extended in use by following the teachings of the present invention.
  • the individual wire bristle 3 may have applied thereto a thin outer plastic coating or sheath 4 of the general type disclosed in Peterson Patent 2,682,734, but with longitudinally spaced enlarged regions which may be conveniently referred to as heads 5 thercalong.
  • the wire core filaments 3 may be crirnped if desired, it is ordinarily much preferred that such filaments e straight, and, in the case of the wheel brush illustrated in FIG. I, extend directly radially outwardly from the central support or hub.
  • bristles in the first place, they enable such straight bristle filaments to be employed with very much more satisfactory results than in the past.
  • the bristles are maintained in relatively uniformly spaced relationship and the bristles also support one another in use in a manner to avoid undue concentrations of stress which would lead to early fatigue and long fracture of the bristles.
  • very hard filaments may be employed with much increased brushing eiiectiveness inasmuch as such bristles do not require to be crimped when treated in the manner just described above.
  • outer plastic coating and beads be bonded to the core filament, and for this purpose various well-known bonding agents may be utilized such as Ty-Ply-S" for bonding rubber and rubber-like materials, and epoxy resins for bonding nylon. Certain other coating materials such as polyurethane may often themselves bond adequately to the core filament without the employment of an adhesive or bonding agent.
  • Polyvinyl chloride has been found satisfactory in producing the beads 5 and 6 and the coating 4, and foamed polyurethane and polyurethane rubber are especially effective.
  • Abrasive granules may, if desired, be incorporated in the plastic coating, and more particularly in the beads 5 to be released at the brush face as the composite bristles wear back in use and there applied to the work by the rotating brush.
  • Such granular abrasive may, for example, include aluminum oxide (Alundum or Aloxite"), silicon carbide (Carborundum, corundum), chrome oxide, natural abrasives (e.g. pumice, emery), and mixtures of these.
  • FIG. 5 of the drawing a further embodiment of the invention is there illustrated wherein the brush bristle filament 3, ordinarily wire, is provided with spaced globules or beads 6 of the plastic material along its length, the wire being uncoated in the intervening regions.
  • the brush fill material may be somewhat more densely packed into the channelform brush back or like supporting element so that a somewhat more dense brush face may accordingly be achieved.
  • the brush is to be operated in a more or less corrosive atmosphere, however, or where the brush filament 3 is of a particularly hard brittle material, it may ordinarily be preferred also to coat such intervening portions of the filaments with a relatively thin film of the protective plastic 4 as shown in FIG. 2.
  • the extreme ends of the filament 3 will in any case ordinarily be exposed at the working face of the brush as shown in FIG. 2 as the coating is quickly abraded away.
  • Such exposed protruding end portion of the filament may ordinarily be as short at for example, or as much as /2 or more in some cases.
  • the spacing of the beads longitudinally of the filament is a matter of choice but may generally preferably be on the order of is" for most purposes although such spacing may likewise vary considerably. Uniform spacing of the beads along the filament is not necessary, and some irregularity of spacing is, in fact, preferred.
  • elastomeric material and preferably foamed elastomcric material 7 may be intruded into the body of brush ma tcrial in the region adjacent the annular hub or support 1 as shown in FlG. 6.
  • Foamed neoprene may be employed in this manner or preferably foamed polyurethane which has proven to be especially satisfactory for the purpose. A so, when a relatively harsh brushing action is desired, such elastomeric material may be thus intruded into the body of brush material between the beaded bristles as at 8 in FIG.
  • Granular abrasive may likewise be included in the body of clastorncric material 8 to be released at the working face of the tool as the latter wears back in use, such body of elastomeric material preferably being of a type adapted to erode at a somewhat greater rate under working conditions than the ends of the bristles themselves.
  • Intrusion of the elastomeric material between the individual bristles of the brush element is greatly facilitated by provision of the aforesaid beads 5 and 6 on such bristles inasmuch as such beads serve to prevent undue compacting of the layer of brush bristle material and hold the bristles uniformly spaced as the elastomeric matrix material is intruded therebetween, interconnecting passages for intrusion of the matrix material being thus maintained by such beads.
  • the basic brush bristle ordinarily employed for most purposes will be steel wire with the heads of spacing material adhered thereto at intervals, but the principles of the invention are also adapted to the employment of bristles having similarly spaced bulges therealong as in the case of nylon monofilarnents having integral bulges 9 of the same material at spaced points along their length (FIG. 8).
  • the straight beaded brush bristle material of this invention is considerably easier to handle in brush making operations than is the springy crimped brush bristle material and lends itself more readily to automatic brush making processes. Due to tangling of the crimped wire, many of the filaments may not extend as radially as possible when assembled into a wheel brush and subsequent high speed rotation will cause movement of such filaments to a more truly radial position with consequent alteration of the brushing face. Employment of straight bristle material instead of crirnped material likewise requires considerably less material for the manufacture of a wheel brush of the same diameter, the saving in material ordinarily being on the order of about 12%. More brush material can be packed into the same brush back, e.g.
  • the beaded brush material of this invention may also be intermixed with other types of bristle material such as Tampico fiber, for example, and such brushes may be treated with tacky fluids in the manner taught in Peterson Patent 2,388,867.
  • Glass filament bristles may also be coated and beaded in accordance with this invention.
  • the so called beads while desirably symmetrically disposed relative to the axes of the bristle filaments as shown, need not necessarily be so disposed but may instead be laterally offset therefrom.
  • neoprene polychloroprene
  • heads 5, or embedding matrix 7, 8 such material may be foamed in well-known manner, if desired, by incorporation of an appropriate blowing agent therein and heating to foam prior to curing.
  • the polyurethane may be caused to foam by the presence of moisture during reaction of the constituent ingredients.
  • the coating 4 and heads 5 may be applied in a continuous process, it is, of course, also optional to apply a continuous thin plastic sheath or coating to the bristle filament core and thereafter apply the beads" or enlarged portions of the same or a different plastic.
  • the inner end portions of the coated filaments may be left without such beads to facilitate packing a larger quantity of brush bristle fill into the channelform or other back or support.
  • the beads may be applied to the bristle filaments, ordinarily prior to assembly into the completed brush, by dropping or printing drops of the plastic on the travelling wire or the like and thereafter severing such wire to proper bristle length. Spraying has also been employed successfully for this purpose.
  • the head forming material should ordinarily be capable of withstanding continuously a service temperature of at least F. and preferably between about 200-250 F. for most purposes.
  • Some polyurethanes may be compounded to withstand temperatures of 3004()0 F.
  • These plastics should preferably be self-extinguishing.
  • Non-foamed plastics may have a tensile strength on the order of 5000 p.s.i., whereas satisfactory foamed plastics may have a tensile strength as low as 10 and as high as 1200 psi. While non-brittle elastomeric materials are much preferred to form such beads, other materials such as drops of solder applied to bristle wires are effective to afford certain of the advantages of the invention.
  • a wheel brush was constructed having an annular channel form hub 4 /2 in diameter within which the brush bristle material was retained by means of a wire retaining ring within the channel, the bristles being doubled thereabout with their ends extending radially outwardly of the hub.
  • the over-all diameter of the brush was 12 /2" and the bristles were .0118" carbon steel wire coated with poly vinyl chloride and provided with beads of the same material as set forth in the specifications above for medium diameter brush fill material.
  • the wires were first given a very thin epoxy resin adhesive coating more firmly to bond the polyvinyl chloride thereto. In operation, the brush was driven at 1750 r.p.m.
