Abstract

1,178,346. Speed responsive brakes; clutch control. EATON YALE & TOWNE Inc. 16 May, 1968 [18 July, 1967], No. 23402/68. Headings F2E and F2L. [Also in Division G3] The description is identical with that of Specifications 1,178,345 and 1,178,347, but the claims relate to a method of continually operating a press precisely at any preselected speed within at least a 4 to 1 range of stroking rates with substantially constant energy being suitable per press stroke.
