    摘要： A hand/foot dual operated lever mechanism for hydraulic jacks includes a short lever-type foot pedal that can be operated by a movable base of a longer lever and that operates a plunger of a pump. A bolt or shaft extends through the foot pedal and the movable base and a side plate of a hydraulic jack. A hidden spring retracts the foot pedal up so that the plunger of the pump can generate a pumping action to lift lifting arm linkages.

    摘要： A motorized jack assemblage for vehicles. This takes the form of a kit containing a motor and reduction gear linkage adapted to be energized from the cigarette lighter or other source of electrical power in the vehicle. The gear linkage is adapted to drive mechanical coupling means, which keys into and operates a lift jack, which in one case is part of the standard equipment for the vehicle, and in another case is a jack with a specialized base which is part of the kit.

    摘要： A lever connecting mechanism for a horizontal hydraulic jack with tension rod comprises a vertical pumping rod having a traversed U-shape connecting member fixed thereon for receiving a bar provided on a foot pedal which is pivotally connected to the structure of the hydraulic jack, and a lever member pivotally connected to the structure of the hydraulic jack. The lever member has the same axis of rotation as the one of the foot pedal so that said lever member can be used to drive said foot pedal toward a downward direction. Since the foot pedal and the lever member are individually supported by two springs at their upmost position, the foot pedal can be depressed without affecting the lever member, but however, the downward movement of lever member will cause the foot pedal being depressed also.
