Abstract: A bearing for a rotating shaft including a main body with three sections. The first section has a square profile whose sides are dimensioned to be received in a corresponding square slot in a support structure and held against rotation. The second section has a profile with at least five sides with four sides thereof being coplanar with the four sides of the first section. The fifth side falls within the profile of the first section and preferably is substantially the same thickness as the support structure plus a retaining clip. The third section has a profile with a portion greater than any portion of the profiles of the first and second sections wherein the bearing can be inserted into the slot in the support structure and held in place with a retaining clip positioned substantially about the second section.

Abstract: A bearing surface for a hollow link of rectangular cross section including a pair of replaceable axially aligned bushings press-fitted into a pair of seats swaged in opposite sidewalls of the link.

Abstract: An integral housing member for removing magnetic articles from a flow of loosely packed material containing a mixture of magnetic articles and non-magnetic articles is shown. The integral housing member includes an inlet cover having an elongated opening, a hollowed-out central area and an opening located at the bottom of the integral housing member which terminates in a rim engaging lip having substantially the same diameter as the top opening of the trash receptacle. A magnetic article assembly is positioned below the elongated opening and is adapted to be rotated about the longitudinal axis of an elongated support shaft. The magnetic article assembly includes a plurality of triangular shaped metal plates, magnetic members and non-magnetic members, all of which have an aperture formed in the center thereof which has the elongated support shaft passed therethrough.

Abstract: An improved bearing structure for a rod which permits both rotational and axial movement of the rod in conjunction with longitudinal bending thereof. Two semi-cylindrical pieces are assembleable along an axial line of separation to enclose a ring of low friction material and form a first cylindrical bearing half while a second cylindrical bearing half is integrally formed for matingly receiving the first half. The two halves of the bearing each include an outer, radially extending flange and are each passed through opposite sides of an aperture in a wall and are assembled into a complete bearing by threadably engaging one another within the hole. The rod to be journaled is inserted through an axial opening formed through the bearing. The axial opening of the second bearing half is constructed with a larger diameter than the anti-friction ring for permitting a select degree of longitudinal bending within the elastic limits of the materials involved.
