Joseph Bramah patented the hydraulic press in 1795. [1] While working at Bramah's shop, Henry Maudslay suggested a cup leather packing. [2] [clarification needed] Because it produced superior results, the hydraulic press eventually displaced the steam hammer for metal forging.

[5] Hydraulic jacks are typically used for shop work, rather than as an emergency jack to be carried with the vehicle.
