    摘要： An arbor press wherein the ram is adapted to be moved by a lever-operated pinion constantly in mesh with a rack attached to a ram carriage, with the ram continuously moved out of the ram carriage by hydraulic pressure. In the application of the hydraulic pressure so as to move the ram out of the ram carriage, a gear-faced lock is initially moved into meshing contact with the rack on the ram carriage so as to lick the same against continuous manual movement while the ram is further moved out of the ram carriage under the force of the hydraulics.

    摘要： A drain valve for a hydraulic shock absorber particularly for use on a large hydraulic press, includes a drain passage carried on a plunger member which is moved downwardly with the movable machine element such as a guide plunger of a press crosshead. The passage defines a valve seat which is closed by a valve disc of relatively great mass under the action of a preset biasing spring. The mass of the valve disc is such that, during a shock movement of the crosshead and the supporting plunger therefor causing a fast movement of the plunger, the seat will move away from the valve disc mass because of the large mass movement of inertia of the disc, and permit flow through the drain valve passage. The plunger will gradually absorb the shock as the fluid in its associated cylinder is displaced out of the drain passage.

    摘要： An overload relief system is provided for a press bolster comprising a ram portion and a cylinder portion. The cylinder portion defines a cavity adapted to receive the ram portion, and the cylinder and ram portions together define a pressure chamber. The pressure chamber is sealed and pressurized, and the relief system functions to relieve the pressure in the chamber in the event of a press overload condition.
