Claims
- 1. A scrubbing plate assembly for use on a carpet scrubbing machine, comprising:
- (a) an annular mounting plate having at least one side adapted for mounting scrubbing elements thereon, said mounting plate being further adapted for attachment to a carpet scrubbing machine;
- (b) a plurality of scrubbing elements, positioned about the perimeter of said mounting plate on one side thereof, each of said scrubbing elements further comprising a rigid back and flexible bristles extending from one side of said back, said back having a pivoting point of attachment whereby said back may be attached to said mounting plate, and a mounting aperture which may be made to align with any one of a series of cooperating mounting apertures in said mounting plate when any of said scrubbing elements is pivoted about its said pivoting point of attachment, and
- (c) means to secure rigidly each of said scrubbing elements when its respective said mounting aperture carried by said rigid back and one of said series of cooperating mounting apertures in said mounting plate are aligned.
- 2. The scrubbing plate assembly of claim 1, wherein said assembly further comprises an adapter means which can be attached to said mounting plate to adapt said assembly for use with carpet cleaning drive hubs of reduced diameter.
- 3. The scrubbing plate assembly of claim 1 wherein each of said scrubbing elements, have leading bristles and trailing bristles, and wherein each of said scrubbing elements are secured to said mounting plate in an orientation allowing the leading bristles of a second scrubbing element to extend radially outwardly from said mounting plate a greater distance than the trailing bristles of a first scrubbing element immediately ahead of said second scrubbing element.
- 4. The scrubbing plate assembly of claim 1, further comprising a glide plate comprising a surface capable of bearing a substantial portion of the weight of a carpet scrubbing machine of the type to which the scrubbing plate assembly is likely to be attached, said glide plate being rigidly attached to said annular mounting plate on the same side of said mounting plate as said scrubbing elements, said surface of said glide plate positioned from the central portion of said annular mounting plate a predetermined distance, said predetermined distance chosen to allow desired contact between said flexible bristles and a carpet to be cleaned.
- 5. The scrubbing plate assembly of claim 4, wherein said glide plate position is adjustable.
- 6. A substantially flat, annular mounting plate having a central aperture therein and adapted for attachment to and use with a circular style floor scrubbing machine, said plate having at least one side thereof adapted for constructing a plurality of brush configurations through the selective positioning of a plurality of individual scrubbing elements which are detachably, rigidly, and independently mountable in spaced relation around said central aperture in one of several predetermined configurations, each configuration yielding a different effective scrubbing diameter, said plate carrying a plurality of groups of mounting apertures surrounding said central aperture, each group of mounting apertures being adapted to accept bolts or similar means to position and secure a respective one of said individual scrubbing elements at a specific location and orientation around said central aperture, said mounting apertures being positioned so that said respective scrubbing elements may be collectively positioned to define a brush configuration having one of several overall scrubbing diameters.
- 7. The mounting plate of claim 6 which further comprises a glide plate capable of supporting a substantial portion of the weight of said floor scrubbing machine, said glide plate mounted coaxially with and substantially within the central portion of said mounting plate, and rigidly attached thereto.
- 8. The mounting plate of claim 6 wherein each group of mounting apertures is substantially identical in configuration.
- 9. The mounting plate of claim 6 wherein said mounting apertures are positioned so that said respective scrubbing elements may be positioned and secured in an orientation wherein, assuming a given direction for the rotation of said mounting plate when in use on said circular style floor scrubbing machine, the leading or initial floor-contacting portion of a given scrubbing element extends radially outwardly from said central aperture a greater distance than the trailing or final floor-contacting portion of that scrubbing element immediately preceding said given scrubbing element.
