    摘要： The press brake safety device includes a vertically movable guard for moving in advance of the press brake ram, a lightweight protector bar movably positioned on the lower edge of the guard for vertical upward movement and means operably connecting an actuation means for the ram to the ram drive means to control ram actuation. Air operated means connect to these ram drive means to render the same inoperable, and air operated control means connect the protector bar and the air operated means to actuate such last named means when the protector bar is moved upwardly in relation to the guard as the guard is being moved downwardly by actuation of the press brake for work engaging action.

    摘要： A portion of a pneumatic circuit for sensing the breakage of a punch is formed by a normally closed passageway in the punch itself. If the punch is broken, the passageway is opened up and pressurized air in the circuit is vented to the atmosphere through the passageway. A pressure differential switch in the circuit senses the resulting pressure change and, in response thereto, produces an electric signal to indicate breakage of the tool.

    摘要： A safety device for machine tools with a tool advancing member in the form of a tool holder performing a tool operating motion during operation and having mechanism for the interruption of the operating motion in the presence of adverse or anomalous operating conditions. According to important aspects of the invention a primary switching or control means is provided for the purpose of interrupting the tool operating motion of the tool holder during a portion of its operating stroke if there is exerted on the tool member a pressure opposing the operating motion. Additionally, secondary switching or control means bridge the primary switching or control means or prevent such from moving into a breaking position as soon as the portion of the operating stroke of the tool has exceeded a predetermined value.
