A frame has a crosspiece with a pair of longitudinal branches, and is used for installing an adapter on earth moving equipment. This equipment has an implement support structure with one or more bearing plates for accommodating azimuthal rotation of a working implement. This working implement is removed from the implement support structure before attaching a frame there. The frame's crosspiece has walls that engage the bearing plates on the implement support structure. An adapter is rotatably mounted on the frame. Any one of a plurality of working accessories can be selected and installed on the adapter. For equipment that originally lacked bearing plates, a cross member with bearing plates is provided in a kit. The frame will then attach to the kit's cross member and to the implement support structure.

Method, apparatus, and kit for providing an adapter on earth moving equipment

A finger seal assembly for use between a stationary member and a movable member is formed of two overlapping metallic members having a solid portion at one end and having fingers at the other end, a layer of high temperature resistant cloth being positioned between said overlapping metallic members; said fingers of one metallic member being bent over the fingers of the other metallic member to hold said fingers together, and said solid portions of said metallic members being welded together, trapping said high temperature resistant cloth between said metallic members. High pressure acts on the inner metallic member to compress the high temperature resistant cloth.

Finger seal assembly

A method for fixing an abradable material of random interlocked metallic fibers sintered and pressed to a specified thickness and density in place on a substrate is set forth where the abradable material bonded to a metal backing plate is placed with the metal backing plate engaging a substrate. The abradable material is compressed without heat to substantially a solid mass at spaced spots; the compressed spots are heated by electrical resistance to a sintering temperature and pressed to form a solid mass. The solid mass of each spot of abradable material is heated to an increased temperature by electrical resistance, welding the solid mass of abradable material to the substrate by completely penetrating the backing plate and forming a weld nugget.
