Abstract
The bar includes two, elongate, rigid members connected together at one end of the bar by a pin and slot connection, and at the opposite end of the bar by a pivotal link, which supports one member for pivotal and translational movement relative to the other member between a retracted position in which the members and link are inclined to each other, and an extended position in which the two members and link are disposed in overlapping, parallel relation. At opposite ends of the bar the two members have pointed ends which are advanced one relative to the other to become imbedded in the confronting surfaces of a pair of adjacent ceiling joists, when the link is swung in a direction to advance the one member relative to the other. A bolt which extends between the two members can be employed to draw the one member into its advanced position relative to the other.
