Claim:
A jack, comprising: a) a mount that is connected to an article to be lifted; b) a first elongated member, wherein said mount engages a side of said first elongated member, and said elongated member traverses said mount along a side of said first elongated member; c) a second elongated member that slidably engages said first elongated member, wherein a lower end of said second elongated member is extendable from a lower end of said first elongated member and below said first elongated member; d) a lever; e) a first pivotal mounting for mounting said lever in communication with said second elongated member; and f) a pivot arm that is pivotally mounted at one end of said pivot arm to said lever and an opposite end of said pivot arm is pivotally mounted to said first elongated member near an upper end of said first elongated member and below said first pivotal mounting; wherein rotation of said lever by said pivotal mounting pushes said second elongated member and forces said second elongated member to slide downwardly relative to said first elongated member, wherein a lower end of said second elongated member contacts a supporting surface, and pushes said mount upwardly.
