"Vintage Machinery" entry for High Speed Hammer Co., Inc.
Description:
The invention relates to riveting machines of the type in which the hammer is cushioned and its helve pivoted to a connecting rod by means of a separate wrist pin. In practice this arrangement is objectionable because of wear of the moving parts and the resultant clatter incident to the play of the parts, especially when the parts become worn. Therefore, it is the purpose of the present invention to minimize the wear, obviate clatter, reduce the number of parts and utilize the cushioning action of the buffers to the best possible advantage. In carrying out the invention the buffers, or cushions, associated with the helve of the hammer and the pitman, are separated by a one piece retainer to which the wrist pin is rigidly connected by means of a pin, or otherwise, to prevent any movement between the said retainer and wrist pin while admitting of said parts being separately formed and readily assembled.
