Disk screen or like shaft assemblies and method of making the same
First Claim
1. A disk screen or like rotatable shaft assembly, comprising:
- an elongate metallic shaft member;
a plurality of metallic disks mounted corotatively on said shaft member and having central shaft-receiving openings complementary to said shaft member but of sufficiently larger size so that edges defining said openings can be in substantially uniformly spaced relation to the shaft member;
nonmetallic spacers between said disks and with inner edge surfaces of the spacers extending inwardly beyond said edges defining said openings and engaging the shaft member;
and means for connecting said disks and spacers together into a modular unit which can be slidably mounted on or removed from the shaft member, and the spacers supporting said disks in cooperation with said connecting means on said spacers with said edges defining said openings substantially uniformly spaced from the shaft member.

Abstract
A disk screen or like shaft structure in which screen disks and spacers are connected together in modular relation. The spacers support the disks with inner edges of the disks spaced from inner surfaces of the spacers so that when the modules are supported on a shaft the inner edges of the disks will be maintained spaced from the shaft. The spacers are preferably made from nonmetallic material such as polyurethane. By placing the modules under predetermined endwise compression, the inner surfaces of the spacers are adapted to be extended inwardly from an initial edge relation generally aligned with the inner edges of the disks. Bolts may serve as the connectors for the disks and spacers for the modules, and facilitate assembling of the modules under endwise compression.

8. A module unit for a disk screen or like shaft assembly, the module being slidably mountable on or removable from a shaft member, and comprising:
-
a limited plurality of disks having central openings defined by edges, for receiving the shaft member therethrough, with said edges spaced from the shaft member; spacers between said disks and having holes therethrough which are generally complementary to said shaft member so that surfaces defining said holes can engage the shaft member; and means for connecting said disks and spacers firmly together in the module and with surfaces extending inwardly relative to the edges defining said disk openings so that said spacers in cooperation with said connecting means will support said disks with said edges of said disks spaced from the shaft member. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method of making a disk screen or like rotatable shaft assembly, comprising;
-
providing an elongate metallic shaft member; mounting a plurality of metallic disks corotatively on said shaft member and the disks having central shaft receiving openings complementary to said shaft member but of sufficiently larger size so that edges defining said openings can be in spaced relation to the shaft member; providing nonmetallic spacers between said disks with surfaces of the spacers extending inwardly beyond said edges and engaging the shaft member; connecting said disks and spacers together by a connecting means into a modular unit which can be slidably mounted on or removed from the shaft member; and supporting the disks by means of the spacers acting in cooperation with said connecting means so that said edges will remain spaced from the shaft member. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A method of making for a disk screen or like shaft assembly, a module unit slidably mountable on or removable from a shaft member, comprising:
-
providing a limited plurality of disks having central openings, defined by edges, for receiving a shaft member therethrough of smaller cross section than said openings; providing spacers between said disks and with holes through the spacers which are generally complementary to said shaft member cross sections so that surfaces defining said holes can engage the shaft member; and connecting said disks and spacers firmly together by a connecting means into the module unit, with said surfaces extending inwardly beyond said edges, and said spacers supporting said disks by acting in cooperation with said connecting means so that said edges will remain spaced from said hole surfaces and positively spaced from the shaft member when the module is engaged on the shaft member. - View Dependent Claims (22, 23, 24, 25, 26, 27)

28. A module unit for a disk screen or like shaft assembly, the module being slidably mountable on or removable from a shaft member, and comprising;
-
a limited plurality of disks having central openings defined by edges, for receiving the shaft member therethrough, with said edges spaced from the shaft member; nonmetallic spacers between said disks and having central holes therethrough which are generally complementary to said shaft member so that surfaces defining said holes can engage the shaft member; a plurality of smaller holes through said disks and spacers located in circumferentially spaced relation about said central holes; bolts extending through said smaller holes and connecting said disks and spacers in the modular unit; and said bolts acting with said spacers for supporting said disks with said edges spaced from the shaft member and said surfaces extending inwardly relative to said edges. - View Dependent Claims (29, 30)
