Interference No. 104,067
'( ...continued)
(a) providing a pair of generally cylindrical relatively
movable surfaces disposed in radially spaced converging relation
and defining at least one rubber tire processing chamber
therebetween having an inlet opening into which rubber tire
material is fed and a discharge opening from which pulverulent
rubber tire material is discharged therebetween for movement of
rubber tire material therethrough, said rubber tire processing
chamber having a plurality of circumferentially spaced inclined
wedge surfaces each defining gradually reducing clearance between
said relatively movable surfaces in the direction of rubber tire
material movement within said rubber tire processing chamber;
(b) imparting relative movement to said relatively movable
surfaces causing movement of said rubber tire material within
said processing chamber;
(C) forcing said rubber tire material to move through said
processing chamber and through into said gradually reducing
clearance defined by said plurality of circumferentially spaced
inclined wedge surfaces, during said relative movement of said
surfaces during said relative movement, said inclined wedge
surfaces applying mechanical compression to said rubber tire
material by wedging activity causing said rubber tire material to
be worked against said metal constituent thereof and mechanically
broken down to a pulverulent form; and
(d) discharging pulverulent rubber tire material from said
outlet following pulverization of said rubber tire material.
5Claim 5 of U.S. Patent No. 5,390,861 to Bishop and claim 26
of Application 08/110,909 to Kramp read as follows:
Apparatus for reducing rubber tire material having metal
stranding to a pulverulent form, comprising:
(a) a generally cylindrical housing;
(b) a generally cylindrical member being located within said
generally cylindrical housing and being disposed in radially
spaced relation therewith;
(C) said generally cylindrical housing and generally
cylindrical member defining a pair of relatively longitudinally
movable surfaces being disposed in diverging relation and
cooperatively defining at least one elongate rubber tire material
processing chamber having first and second ends, said first end
