A pair of bowstring interconnected wings are pivotally connected to the other end of the casing with the wings being normally biased forwardly in aligned position transversely of the casing by a compression spring within the casing moving a flexible element entrained around arcuate portions of the wings longitudinally of the casing. Toggle linkage, contained by the casings, bears against one end of the compression spring to increase its article projecting potential following intital cocking of the bowstring.
