JACK STAND

A jack stand comprising a hollow column supported in an upright perpendicular position by a base plate at its lower end with a post telescopically supported within its upper end for extension relative thereto and a saddle at the upper end of the post. A pin mounted in inclined slots in the column by engagement with one of a plurality of notches on the post holds the latter at a predetermined position of extension. The pin is movable in the slots from an operative position supporting the post to an inoperative position to allow the post to be moved upwardly or downwardly relative to the column and back to an operative position in engagement with a different notch. There is a secondary support in the form of a plate at the top of the column movable into engagement with another notch and there is linkage interconnecting the pin and plate such that movement of the pin into and out of operative position is accompanied by movement of the plate into and out of operative position.
