Abstract
294,096. Gridley Machine Co., (Assignees of Montgomery, D. H.). July 16, 1927, [Convention date]. Fluid-pressure. - In hydraulically-operated presses, brakes, work-holding chucks, &c., liquid supplied from an accumulator moves the actuated member rapidly, and thereafter a pump exerts a constant pressure on the member and also supplies the accumulator. The pump 11 delivers to a passage 13 in which is a valve 19 controlling the supply to and exhaust from a cylinder 17. The accumulator 25 is charged through a passage 26 when the pressure in the passage 13 is sufficient to open the adjustablyloaded valve 27, and delivers to the passage 13 through a check valve 36 when the pressure in the passage 13 is reduced by opening the valve 19. A relief valve 40 is provided, and the mechanism may be disposed in a tank 10.
