ABSTRACT:
For use in establishing the prescribed elevation difference between an adjustably movable deck member and a relatively stationary support member, an elevation gauge comprising a case, a contact carrier disposed in the case and guided for vertical movement, a lead screw for moving the contact carrier, a scale carried by the contact carrier to extend vertically upwardly and to cooperate with an indicator pointer carried by the case to indicated the selected vertical position of the contact carrier, a second contact carrier guided for vertical movement on the case, and a signal device for providing an output when the second contact carrier is in a preselected elevational position relative to the first contact carrier. A plunger coupled to the signal device cooperates between the first and second contact carriers, and the case is adapted to rest on one of the members while the said second contact carrier is adapted to rest on the other of said members. A plurality of bolt assemblies is provided for adjustably supporting the deck member on the support member. Each bolt assembly comprises a vertically extending bolt, a hanger for mounting on the support member, with the upper end of the bolt penetrating through the hanger and being rotatable relative to the hanger. A first nut threadedly engages the upper end of the bolt and restrains the bolt against movement downwardly relative to the hanger. A second nut threadedly engages the bolt and supports the deck member, the second nut being prevented from rotating when the bolt rotates. The first nut and the upper end of the bolt are proportioned and designed to be engaged by a tool and rotated together relative to the hanger to raise and lower the deck member to the prescribed height determined by the said gauge.
