Abstract
150,964. John, F. Sept. 11, 1919, [Convention date]. Power hammers; metal-working presses.-In reciprocating presses and machines such as power hammers and shearing machines, of the type in which the die or tool is driven from a crankshaft or its equivalent mounted at an intermediate point in a lever or retaining arm adapted to yield under abnormal pressure, the pivot of the lever is made sufficiently large to surround the crankshaft and thus form a bearing-block integral with the arm. Fig. 1 shows the device adapted to a crank-operated machine, the crank-shaft 6 being eccentrically mounted in a journal 8 normally held against rotation by an arm 10 connected to a lug on the framing by an easily breakable bolt 13. Instead of the bolt, a spring may be used. Fig. 7 shows the adaptation to a double toggle press holding a rod 20 in dies 2, 3, the arms of the two journals 8 being connected by the bolt. The device may also be applied to a single toggle press and to the lower parts of the press instead of to the head.
