Patent ID: 8201807

Claim:
A jack stand in combination with a hydraulic jack comprising: a jack stand having: a platform for providing stable support; a base attached to the platform, the base defining a receptacle configured to slidingly receive a column; a column having an upper end and a lower end, the lower end slidingly received within the receptacle; a locator member for precise location under an object to be lifted, the locator member being attached to the upper end of the column and including a first planar horizontal surface for contact with the object to be lifted; a plate member connected to the upper end of the column, the plate member extending substantially at a right angle to the column and including a second planar horizontal surface for contact with the object to be lifted; wherein the first planar horizontal surface is substantially co-planar with the second planar horizontal surface; and a hydraulic jack positioned on the platform, the hydraulic jack having: an elongate piston movable upwardly in relation to the hydraulic jack for elevating a load, the piston having a terminal end, wherein, the hydraulic jack is positioned adjacent the jack stand such that the elongate piston is positioned alongside of and parallel with the elongate column; and the terminal end of the piston is positioned in contact with a lower surface of the plate member, whereby, when the piston is moved upwardly under a load in relation to the hydraulic jack, the plate member is moved upwardly to elevate the load, the column is moved upwardly, and the locator member is moved upwardly in unison with the plate member; wherein, the jack stand further includes a means for mechanically holding the column in a selected one of a plurality of different elevated positions in relation to the base; and further wherein, the hydraulic jack is removable from the platform when the column is being held in an elevated position by the means for mechanically holding the column.
