Abstract

900,067. Friction drop hammers. BRETT'S STAMPING CO. Ltd. Feb. 21, 1961, No. 6269/61. Class 83 (4). The friction board 10 of a board-type drop hammer has its friction surfaces faced with separate sheets 13 of a tough material having a low flow rate and high coefficient of friction. The sheets 11 are preferably of fibre and are secured in recesses 11, 12 of a laminated board of Danish beech, by an epoxy resin adhesive assisted by countersunk head copper rivets; slight side clearance is provided between the sheets. In another embodiment, Figs. 2, 3 (not shown), the sheets extend diagonally across the board and are fitted in separate recesses separated by lands. The sheets on opposite sides of the board extend in diagonally opposite directions.
