Abstract
Abstract Footwear, tires and apparatus for manufacturing the same. The articles have untreated traction grooves formed therein and friction-providing surfaces contiguous to said traction grooves. Apparatuses for producing the respective articles include a fiberglass mat or equivalent upon which adhesives and abrasives are embedded on sandpaper manufacturing equipment and further includes a piercing cut out means the cuts out footwear soles from the treated mat to suit design. Apparatus for producing tires having traction and friction surfaces is housed within a pit or well so that a vehicle may be driven into position thereatop so that such apparatus may treat the vehicles tires as desired by harnessing the weight of the vehicle to achieve the desired embedding.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
335 words
An apparatus for improving the friction-related and traction-related qualities of a tire having a tread formed by raised, road-contacting surfaces and depressed, non-road contacting surfaces, comprising, a pit formed in a support surface, a first pair of vertically spaced roller members comprising an upper roller member and a lower roller member, a first belt member disposed in interconnecting relation between said first pair of upper and lower roller members, a second pair of vertically spaced roller members comprising an upper roller member and a lower roller member, a second belt member disposed in interconnecting relation between said second pair of upper and lower roller members, said first and second pairs of roller members longitudinally spaced from one another by a distance sufficient to accommodate therebetween a vehicle tire, said first and second pairs of roller members disposed within said pit so that the respective upper roller members of said first and second pair of roller members are positioned substantially coplanar with said support surface, said vehicle tire contacting said first and second belt members at circumferentially spaced contact-regions thereon, a first reservoir member for the storage of an adhesive, said first reservoir member adapted to discharge said adhesive at preselected rates of discharge onto said first belt member at a point intermediate said first pair of upper and lower roller members, a second reservoir member for the storage of particulate, said second reservoir member adapted to discharge said particulate at preselected rates onto said second belt member at a point intermediate said second pair of upper and lower roller members, said first and second belt members positioned so that their axes of rotation are parallel to the axis of rotation of the tire, and a common belt-rotation means to impart unidirectional and uniform rate rotation to said first and second belt members so that adhesive is applied to said tire by said first belt member and so that said particulate is applied to said tire by said second belt member subsequent to said adhesive application.
Claim 2
Independent Claim
335 words
An apparatus for improving the friction-related and traction-related qualities of a tire having a tread formed by raised, road-contacting surfaces and depressed, non-road contacting surfaces, comprising, a pit formed in a support surface, a first pair of vertically spaced roller members comprising an upper roller member and a lower roller member, a first belt member disposed in interconnecting relation between said first pair of upper and lower roller members, a second pair of vertically spaced roller members comprising an upper roller member and a lower roller member, a second belt member disposed in interconnecting relation between said second pair of upper and lower roller members, said first and second pairs of roller members longitudinally spaced from one another by a distance sufficient to accommodate therebetween a vehicle tire, said first and second pairs of roller members disposed within said pit so that the respective upper roller members of said first and second pair of roller members are positioned substantially coplanar with said support surface, said vehicle tire contacting said first and second belt members at circumferentially spaced contact-regions thereon, a first reservoir member for the storage of an adhesive, said first reservoir member adapted to discharge said adhesive at preselected rates of discharge onto said first belt member at a point intermediate said first pair of upper and lower roller members, a second reservoir member for the storage of particulate, said second reservoir member adapted to discharge said particulate at preselected rates onto said second belt member at a point intermediate said second pair of upper and lower roller members, said first and second belt members positioned so that their axes of rotation are parallel to the axis of rotation of the tire, and a common belt-rotation means to impart unidirectional and uniform rate rotation to said first and second belt members so that adhesive is applied to said tire by said first belt member and so that said particulate is applied to said tire by said second belt member subsequent to said adhesive application.
Claim 3
Dependent Claim
34 words
The apparatus of claim 1, wherein the first and second belt members respectively interconnecting said first and second pair of upper and lower roller members are disposed in substantially parallel relation to one another.
Claim 4
Dependent Claim
74 words
The apparatus of claim 2, further comprising a first nozzle member associated with said first belt member and a second nozzle member associated with said second belt member, said respective nozzle members confluent with their respective reservoir members and positioned to deposit the respective contents of the reservoir members on said respective belt members at a point intermediate the respective upper and lower roller members of said pairs of upper and lower roller members.
