Abstract
A safety brake for use on presses that provides a positive stop which is positioned so that its braking surfaces will be engaged if the press overtravels its normal home position due to failure of the standard clutch and brake system of the press. The braking surfaces of the emergency brake are moved to a released position when the press is energized to begin a cycle of its operation. Once the released braking surfaces have passed by each other during the normal cycle of press operation, they are returned to their braking positions so as to preclude overtravel of the press past its home position to any substantial degree if the conventional brake of the press should fail.
