Abstract
Abstract Apparatus for use in applying wax to an object and/or polishing the object. The apparatus includes a housing, an electric motor positioned within the housing and an operating shaft driven by the motor. A generally disk-shaped pad holder has a hub connected to the operating shaft with a holder having a first surface facing the housing and a second surface facing away from the housing. The apparatus further includes a pad of sponge-like material carried by the holder and positioned against the second surface of the holder. The apparatus also includes a bonnet of cloth material positioned about the pad and having an elastic band adjacent its periphery for holding the pad to retain the bonnet in its installed position. The pad holder includes an annular lip adjacent the periphery of the holder with the lip extending towards the housing and radially outwardly so that the bonnet can in its installed condition engages the lip to locate the bonnet and limit its inward movement.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
173 words
Apparatus for use in applying wax to an object and/or polishing the waxed object, said apparatus comprising: a housing, an electric motor disposed within said housing, and an operating shaft, driven by said motor; a generally disk-shaped pad holder having a hub connected to said shaft, said holder having a first surface facing said housing and a second surface disposed away from said housing; a pad of sponge-like material carried by said holder and positioned against said holder second surface; a bonnet of cloth material disposed about said pad and having means adjacent its periphery for holding said pad to retain said bonnet installed about said pad, said holder including an annular lip disposed adjacent the periphery of said holder, said lip extending toward said housing and radially outwardly, the bonnet in its installed condition engaging said lip to locate said bonnet and limit its inward movement, said pad extending radially outwardly of said holder, said pad and said lip defining an annular cavity for receiving the means for holding of said bonnet.
Claim 2
Dependent Claim
173 words
Apparatus for use in applying wax to an object and/or polishing the waxed object, said apparatus comprising: a housing, an electric motor disposed within said housing, and an operating shaft, driven by said motor; a generally disk-shaped pad holder having a hub connected to said shaft, said holder having a first surface facing said housing and a second surface disposed away from said housing; a pad of sponge-like material carried by said holder and positioned against said holder second surface; a bonnet of cloth material disposed about said pad and having means adjacent its periphery for holding said pad to retain said bonnet installed about said pad, said holder including an annular lip disposed adjacent the periphery of said holder, said lip extending toward said housing and radially outwardly, the bonnet in its installed condition engaging said lip to locate said bonnet and limit its inward movement, said pad extending radially outwardly of said holder, said pad and said lip defining an annular cavity for receiving the means for holding of said bonnet.
Claim 3
Dependent Claim
48 words
Apparatus as set forth in claim 1 wherein said lip extends closer to said housing than does the installed bonnet so that threads resulting from fraying and unraveling of the material of said bonnet become trapped in said cavity to prevent them from becoming entangled with said shaft.
Claim 4
Dependent Claim
16 words
Apparatus as set forth in claim l wherein the distal end of said lip is bulbous.
Claim 5
Dependent Claim
25 words
Apparatus as set forth in claim 1 wherein said holder further comprises an inner annular strengthening rib extending from said first surface toward said housing.
Claim 6
Dependent Claim
18 words
Apparatus as set forth in claim 1 wherein said pad holder is made of glass filed acrylonitrile-butadiene-styrene (ABS).
Claim 7
Dependent Claim
37 words
Apparatus as set forth in claim 1 wherein said first surface is generally planar and said lip extends with respect to the plane of said first surface of an angle of between 30 degrees and 60 degrees.
Claim 8
Dependent Claim
18 words
Apparatus as set forth in claim 6 wherein said lip extends from said plane at about 45 degrees.
Claim 9
Dependent Claim
173 words
Apparatus for use in applying wax to an object and/or polishing the waxed object, said apparatus comprising: a housing, an electric motor disposed within said housing, and an operating shaft, driven by said motor; a generally disk-shaped pad holder having a hub connected to said shaft, said holder having a first surface facing said housing and a second surface disposed away from said housing; a pad of sponge-like material carried by said holder and positioned against said holder second surface; a bonnet of cloth material disposed about said pad and having means adjacent its periphery for holding said pad to retain said bonnet installed about said pad, said holder including an annular lip disposed adjacent the periphery of said holder, said lip extending toward said housing and radially outwardly, the bonnet in its installed condition engaging said lip to locate said bonnet and limit its inward movement, said pad extending radially outwardly of said holder, said holder terminating in said lip so that said bonnet does not encompass any portion of said holder.
Claim 10
Dependent Claim
173 words
Apparatus for use in applying wax to an object and/or polishing the waxed object, said apparatus comprising: a housing, an electric motor disposed within said housing, and an operating shaft, driven by said motor; a generally disk-shaped pad holder having a hub connected to said shaft, said holder having a first surface facing said housing and a second surface disposed away from said housing; a pad of sponge-like material carried by said holder and positioned against said holder second surface; a bonnet of cloth material disposed about said pad and having means adjacent its periphery for holding said pad to retain said bonnet installed about said pad, said holder including an annular lip disposed adjacent the periphery of said holder, said lip extending toward said housing and radially outwardly, the bonnet in its installed condition engaging said lip to locate said bonnet and limit its inward movement, said pad extending radially outwardly of said holder, said holder terminating in said lip so that said bonnet does not encompass any portion of said holder.
Claim 11
Dependent Claim
175 words
Apparatus for use in applying wax to an object and/or polishing the waxed object, said apparatus comprising: a housing, an electric motor disposed within said housing, and an operating shaft driven by said motor; a generally disk-shaped pad holder formed of a relatively stiff thermoplastic material and having a hub connected to said shaft, said holder having a first surface facing said housing and a second surface facing away from said housing; a pad of relatively soft sponge-like material adhered to said holder second surface and extending radially beyond said holder, said holder terminating radially outwardly in an annular lip extending from said first surface toward said housing and radially outwardly, said pad and lip defining an annular cavity; and a bonnet of cloth material disposed about said pad and having holding means adjacent its periphery for retaining said bonnet in an installed condition, said holding means being received in said cavity, at least one portion of said bonnet being frayed, threads resulting from unraveling of the bonnet material being also received in said cavity.
