Definitions

  • the present invention relates to rug and carpet scrubbers and more particularly to a rotary brush for attachment to a modied vertical axis two brush floor polisher raving means for dispensing a detergent solution to the brushes.
  • An object of the present invention is to provide a rotary annular brush body having at least one row of brush bristles or other flexible pile contacting elements with the upper ends thereof secured in a downwardly facing recess in the body to permit lateral flexing thereof, with a surface contacting support centrally on one or both sides of the recess with its supporting surface slightly above the ends of the surface contacting elements to limit llexing thereof.
  • an annular detergent receiving recess is formed in the body above the support with detergent dispensing openings in the bottom wall of the recess discharging detergent onto the carpet.
  • the upper ends of the bristles are secured to an annulus of thermoplastic material detachably received in a downwardly facing annular recess formed in an annular brush body of plastic material such as a phenolic compound adjacent to its periphery.
  • the bristles extend below the brush body and the downwardly facing recess is so formed that the bristles have lateral freedom for flexing movement during use.
  • the body is formed with an annular support with its supporting surface positioned slightly above the lower ends of the bristles so that when pressure is applied the supporting surface will limit movement of the bristles into the nap of a rug or carpet.
  • the support is also formed to limit the inward liexing of the bristles.
  • the body Centrally and inwardly of the annular support the body is formed with a through opening, the walls of which are provided with means for detachabtly and drivingly connecting the brush to a vertical axis rotary shaft of a floor polisher.
  • the lower end of the through opening is closed by a metallic plate which supplements the supporting action of the annular support.
  • the body In its upper side between the wall forming the central -through opening and inner wall of the downwardly facing recess, the body is formed with an annular detergent receiving recess having an annular row of detergent dispensing openings formed in the outer perimeter of its lower wall which is formed by the annular support.
  • the outer wall of the detergent receiving recess may be tapered inwardly lto prevent detergent from climbing upwardly due to centrifugal action.
  • the taper may be formed integrally with the outer wall of the detergent receiving recess but for better molding practice it is preferably made as a separate annular tapered ring.
  • the bristle supporting ring may be so made as to be frictionally held in the downwardly facing recess but preferably dimples are formed on the outer edge of the bristle supporting ring which engage over shoulders formed in the outer wall of the downwardly facing recess. ln either case knocloout openings are formed in the upper and outer walls of the downwardly facing recess. When dimples are provided the lower edge of the knock-out openings may form the shoulders which are engaged by the dimples.
  • the bristle supporting ring is also provided with driving lugs which interiit with recesses formed in the outer wall of the downwardly facing recess.
  • FIG. l is a top view of the shampoo brush according to the invention.
  • FIG. 2 is a cross sectional view taken through the center of the brush and one of the knock-out openings.
  • the reference numeral 10 generally represents the brush body and 11 generally represents the removable bristle assembly.
  • the brush body 10 may be made of any suitable plastic material such as a phenolic compound which is rigid enough for the purpose and is easily moldable to the desired shape.
  • the body 1li is annular in shape and is formed with a downwardly facing bristle receiving recess 12 adjacent to its periphery which is formed by an outer annular wall 13, an inner annular wall 14 and a top wall 15.
  • annular support 16 Inwardly of the wal-l 14 is an annular support 16 which also forms the bottom wall of an annular detergent receiving recess 17 formed in the upper side of the body 10.
  • the body 1lb is formed with a through opening 18., the annular wall 19 of which also forms the inner wall of detergent recess 17. lnteriorly the opening is formed with a driving connection 20 of any suitable character for .drivingly connecting the body 10 to a vertical axis drive shaft of a floor polisher.
  • the support 16 is provided with an annular row of detergent dispensing openings 21 which connect the detergent recess 17 to the space beneath the support 16 for a purpose which will presently appear.
  • the outer wall 14 of detergent recess 17 may be tapered inwardly toward the top to prevent detergent from being thrown out by centrifugal acti-on.
  • a separate tapered annulus 22 may be provided for the same purpose.
  • annulus 22 is to be considered as a part of wall 14 whether it be integral therewith or not.
  • the outer wall 13 and the top wall 1S of recess 12 are formed with a plurality of cut-outs 23 which form shoulders 24 for a purpose which will later appear.
  • outer wall 13 of recess 12 is formed with an offset 25, in which is formed a plurality of drive recesses 26 which form a part of a driving connection between the body 10 and the brush assembly as will later appear.
  • the bristle assembly 11 includes an annular ring 27 of suitable thermoplastic material having the necessary strength and into which staples may be driven.
  • the ring 27 is of a suitable outside diameter that it will frictionally engage the inner periphery of wall 13 so as to be held in place by friction alone or dimples 23 may be provided for engaging over shoulders 24 as shown in FIG. 2.
  • the ring 27 is of sufficient resiliency that pressure may be applied to it at the cut-outs 23 to remove the dimples 2S from the shoulders 24 and thus release the brush assembly from the brush recess 12.
  • a plurality of bristle receiving openings 29 are formed in the ring 27 and into each of which are stapled bristle tufts 30 to form an annular row of bristles.
  • the tufts 3d are of sufficient length to extend below the annular support 16 so as to support the brush when no pressure is applied.
  • the recess 12 is wide enough to permit lateral flexing of the tufts 30 when the device is in use, the amplitude of the exing being limited by the lower edge of wall 13 and the outer perimeter of the support 16.
  • Drive lugs 31 are formed on the outer periphery of ring 27 and coact with the drive recesses 26 to positively rotate the bristle assembly 11 with the body 10.
  • a metallic closure plate 32 closes the lower end of central opening ll and aids the annular support lo in its supporting function as will appear.
  • rl ⁇ he lugs 33 are primarily for molding purposes but also will cause the detergent in recess i7 to rotate with the body 1d and thus help guide it to the dispensing openings 2l.
  • the outer annular wall 13 is not absolutely essential but it does prevent detergent from being thrown outwardly to some extent, helps to support the polisher and forms a limiting stop for the outward flexure of the bristles 30.
  • the inner wall 14 forms a limiting stop for the inward iiexure of the bristles.
  • a shampoo brush comprising an integral molding of plastic material, said molding including an inner vertically extending annular wall having a bore formed with means for the attachment of the brush to the drive shaft of a floor polisher, a second vertically extending annular wall spaced radially outward from said first annular wall, a bottom wall connecting the bottom ends of said iirst and second annular walls and formed with openings extending therethrough adjacent the lower end of said second annular wall, the space between said rst and second annular walls forming an upwardly opening deep annular cavity for receiving detergent solution for application to the floor being cleaned, a third vertically extending annular wall spaced radially outward from said second annular wall, a top wall connecting the upper ends of said second and third annular walls, the lower end of said third annular wall being in alignment with the lower surface of said bottom wall, the spaceV between said second and third annular walls forming a downwardly opening annular recess adjacent the periphery of said molding and an annular brush positioned in said annular rece
