Brake shoe salvaging means

A brake shoe salvaging means for removing rivets from a brake shoe table for replacement of the brake lining thereof, the brake shoe table being generally in the form of an arc of a cylinder, to the outer or convex side of which a replaceable brake lining is held by rivet means which extend from the brake lining through holes provided in the brake shoe table in a radial direction with respect to the cylindrical nature of the brake shoe table, the brake shoe salvaging means comprising:

• a plate means;
• means supporting the brake shoe table and plate means in operative juxtaposition as hereinafter set forth;
• the plate means having a pattern of pin means facing the brake shoe table and arranged in a pattern operatively corresponding to the pattern of rivet holes in the brake shoe table;
• the pin means having their outer ends in a plane or in the form of a curved surface whose curvature differs from that of the brake shoe table;
• pressure means urging the brake shoe table and plate means operatively toward one another in a forceful manner operative to force the pin means operatively through the corresponding rivet holes of the brake shoe table to thereby drive the rivets therefrom;
• and
• pressure means causing an operative relative rocking of the brake shoe table and the plate means to cause, sequentially or successively, corresponding portions of the brake shoe table rivet holes and pin means to come into the said forceful manner contact, thereby to successively drive from their rivet holes successive ones or groups of the rivets of the brake shoe table.
