Abstract: A carrier of the backpack type is disclosed, for use by firefighters in transporting a smoke ejector to a location within the building where it is to be used in removing smoke from the building interior. A back plate may be quickly strapped to the firefighter's back, and includes a first pair of clamp elements affixed to the back plate. Second and third pairs of movable clamp elements are carried by a pair of transversely spaced bars mounted on the back plate for slidable and rotatable movement. The second and third pairs are spaced longitudinally of the bars, so that either movable pair of clamp elements can be used in cooperation with the fixed clamps, to engage the frame of a smoke ejector. The bars are under spring bias tending to urge the selected pair of movable clamp elements toward the fixed pair, for quickly and securely gripping the smoke ejector frame.
