Definitions

  • My present invention relates to a brush for the cleaning of pipes and other ducts such as, for example, the tubes of a boiler.
  • a more particular object of this invention is to provide means in such brush for conveniently adjusting the shape' and, with it, the degree of flexibility of the bristle-carrying body whenever such resetting is required because of the fatiguing of the elastomeric material.
  • a pipe-cleaning brush whose bristle-carrying cylindrical body is of a tubular construction and rests, at least by its ends, on a rigid cylindrical support between a pair of end members whose axial separation is adjustable for the exertion of axial pressure upon the tubular body whereby the latter bulges outwardly to assume a generally barrel-shaped configuration.
  • This configuration is, of course, also shared by the surrounding set of bristles which advantageously form tufts set in a multiplicity of pits on the outer surface of the body.
  • a flexible but substantially inelastic inner liner such as a fabric sheet, is advantageously bonded to or imbedded in the surface of the body to strengthen it against excessive deformation.
  • the tubular bristle carrier of my improved brush may be made in a single piece, without any scams or joints, and can thus be manufactured not only from natural rubber but also from a variety of synthetic elastomers which are not readily susceptible to heat sealing.
  • the rigid support for the tubular elastomeric body is rotatably journaled on an extension of a brush handle so that the array of bristles may turn freely, e.g. when following a helicoidal channel on the inner wall of a pipe to be cleaned.
  • FIG. 1 is an axial sectional view of a pipe brush embodying my invention
  • FIG. 3 is a view similar to FIG. 2, showing a modification of the previous embodiment.
  • FIG. 4 is a view similar to FIG. 1, illustrating a further embodiment.
  • FIG. 1 shows a cylindrically tubular body 1 of rubber or other elastomeric material whose outer surface is formed with two annular peripheral grooves 10 at the ends and with a multi plicity of pits 11 accommodating tufts of bristles 12 between these grooves.
  • a flexible but practically inelastic textile liner has been shown at 20.
  • Body 1 is mounted on a rigid support which comprises a cylindrical sleeve 2 terminating at a shoulder 29 in a flared skirt with a frustoconical portion 30 and a cylindrical portion 31.
  • a flange 17 of the latter portion bears upon an end face 19' of body 1 and forms one of two end members adapted to exert axial pressure upon that body, the other end member being a collar 3 which is screwed onto a male thread 15 of sleeve 2 and which has a flange 22 bearing upon the opposite face 19" of body 1.
  • Lugs 16 and 18 on collar 3 and support portion 31 facilitate relative manual rotation thereof to change the spacing between the two flanges 17 and 22, thus enabling the exertion of axial pressure upon the body 1 which thereupon bulges outwardly so that the tips of its bristles 12 lie on a generally-barrel-shaped surface 12'.
  • This outward bulging of the body 1 allows the bristles 12 to yield inwardly, without breaking or buckling, whenever the brush encounters an obstruction within a pipe or other duct to be cleaned.
  • Sleeve 2 is rotatably mounted on a central rod 5 forming an axial extension of a handle 9.
  • Rod 5 terminates at one end in a set of peripheral ribs 24 by which it is anchored to a bell-shaped coupling member 4 having a cylindrical mouth 26 with a female thread 23 engageable with a complementary male thread on handle 9.
  • member 4 connected with its mouth 26 through a tapered transition portion 28, bears through a washer 8 upon the shoulder 29 to form one end stop for the latter, another end stop being constituted by a cap nut 13 which engages a male thread 14 on the projecting free end of rod 5 and which is integral with an eye 6; the latter may be used to anchor the brush to a cable for pulling it through a pipe and, during periods of non-use, also serves for suspending the brush from a hook.
  • a cotter pin may be driven through holes 7 in sleeve 2 and aligned holes in cap 13 for preventing any unscrewing thereof.
  • sleeve 2a is formed on opposite extremities with respective male threads 15a and 24a engaged by relatively rotatable end members 3a and 38, these end members being provided with respective lugs 16a and 18a to facilitate their adjustment.
  • a shoulder 33 adjacent thread 24a forms an end stop for member 38 which, in the assembly of the brush, is first screwed onto the sleeve 2a until it reaches its terminal position. Thereafter, member 3a is screwed onto thread 15a until the bristles 12a assume the desired barrel-shaped contour 12a.
  • a hollow coupling member 34 serves to lock the sleeve 2a against axial motion after being slid into an extremity of rod 5a to which it may be secured by a cotter pin passing through aligned holes 36 and 37; this member has rn-ale threads 35 by which it may be fastened to a handle that has not been shown but may be generally similar to handle 9.
  • rod 512 is integral with eye. 6b and with a shoulder 14 forming one end stop for sleeve 2b; another end stop is constituted by a ring nut 59 which is screwed onto a thread 46 on the opposite end of rod b and has an inner flange 47 limiting its axial displacement toward shoulder 41. Bores 69 in the exposed surface of nut 5% facilitate its rotation by a suitable tool.
  • Rod 5b is recessed between its enlarged ends 42 and 43 which alone serve for the rotatable support of sleeve 2b.
  • the bulging shape of bristles 12b has been indicated at 12b.
  • the support for tubular body includes a cylinder 51 which underlies the major part of the inner periphery of tubular body 10 and has an end flange 55 bearing axially upon the latter.
  • Cylinder 51 is threaded at 53 onto a disk 48 which, in turn, is screwed onto a thread 49 of sleeve so as to come to rest against a shoulder 50 thereof.
  • An inner flange 52 of cylinder 51 rides on the remote end of sleeve 20 and confronts a disk 56 which is screwed onto a male thread 57 of the sleeve and has a flange 58 forming the other pressure-exerting end member of the supporting structure for body 1c.
  • the presence of cylinder 51 positively prevents any inward deflection of body 1c whose outward curvature, paralleling the bulging contour 120 of bristles 12c, has been indicated at 10.
  • the assembly of this brush is analogous to that described in connection with FIG. 2.
  • a pipe-cleaning brush comprising a cylindrical tubular body of elastorneric material; rigid cylindrical support means for said body and engaging the ends thereof; handle means connected with said support means; a pair of end members mounted on said support means and having freedom of relative axial adjustment for exerting axial pressure upon said body, thereby causing same to bulge outwardly; and a set of bristles extending generally radially outwardly from the periphery of said body.
  • a pipe-cleaning brush as defined in claim 5, comprising an eye integral with said free end, said eye having a shoulder forming said abutment means.
