Suspension idler

Claim 2

A conveyor idler comprising: a. an elongated, flexible, solid molded polymer idler member having a plurality of rollers formed thereon each roller having a friction surface molded therein, said idler member having a pair of enlarged end portions molded thereon; b. a pair of terminal supports, each said terminal support having a pair of polymer members shaped to enclose one said enlarged end portion of said conveyor idler and a casing holding said pair of polymer members therein; and c. mounting means attached to each said terminal support for mounting said terminal support to a conveyor idler support framework whereby a conveyor may be supported by a one-piece flexible and rotatable idler.

Claim 3

The apparatus in accordance with claim 1 in which said one-piece elongated polymer flexible idler member is a one-piece molded, elongated ureathane idler member.

Claim 4

The apparatus in accordance with claim 2 in which each roller friction surface is a tread which alternates with the tread on each adjacent roller.

Claim 5

The apparatus in accordance with claim 3 in which each said terminal support has a water line connected thereinto for feeding water thereinside.

Claim 6

The apparatus in accordance with claim 4 in which said mounting means includes a pin passing through each said terminal support for connecting said terminal support to said mounting framework.

Claim 7

The apparatus in accordance with claim 5 in which said pin is a stainless steel pin adapted to be hooked into a bifurcated stirrup.

Claim 8

The apparatus in accordance with claim 6 in which said terminal supports with polymer members are made from an acetal resin.

Claim 9

The apparatus in accordance with claim 3 in which said terminal supports have a grease fitting for applying grease thereinto.

Claim 10

The apparatus in accordance with claim 7 in which the enlarged end portions of said idler member has radiused surfaces at the connection with said idler member.

Claim 11

A conveyor idler and terminal bearing apparatus comprising in combination: mounting means for mounting a conveyor idler for supporting a movable conveyor belt; elongated, flexible conveyor idler having a plurality of rollers formed thereon and having a pair of end portions each having a bearing member attached thereto; a pair of terminal bearing supports for supporting each said bearing member on each end portion of said elongated, flexible conveyor idler, each said terminal bearing support having a plurality of supporting members at least partially enclosing each said bearing member to support each said bearing member in each said terminal bearing and casing covering said plurality of support members; and at least one pin passing through said casing and support members to said mounting means.

Claim 12

A conveyor idler and terminal bearing apparatus comprising in combination: mounting means for mounting a conveyor idler for supporting a movable conveyor belt; elongated, flexible conveyor idler having a plurality of rollers formed thereon and having a pair of end portions each having a bearing member attached thereto; a pair of terminal bearing supports for supporting each said bearing member on each end portion of said elongated, flexible conveyor idler, each said terminal bearing support having a plurality of supporting members at least partially enclosing each said bearing member to support each said bearing member in each said terminal bearing and casing covering said plurality of support members; and at least one pin passing through said casing and support members to said mounting means.

Claim 13

The apparatus is accordance with claim 10, in which said casing includes a hollow, cylindrical sleeve, closed at one end, for sliding over a pair of semi-cylindrical support members and having a metal pin passing through said cylindrical sleeve casing and support members and connecting the support members onto said bearing member in said idler.

Claim 14

The apparatus in accordance with claim 11 in which said elongated flexible polymer conveyor idler rollers each have a predetermined tread design thereon.

Claim 15

The apparatus in accordance with claim 11, in which said bearing member is an enlarged polymer end portion molded onto each end of said idler.
