  • Patent number: 4625945
    Abstract: A pry bar wedge member adapted for use in the removal of forms, such as wooden forms, from poured concrete, or the like. The wedge member includes a striking surface thereon for aiding in forcing the member between the form and the poured and hardened concrete, and also includes ratchet means adapted for coaction with a breaker bar lever, for applying leverage force to the wedge member, in the operation of prying the forms loose from the poured concrete. An advantage of the pry bar wedge member is that it is useable in restricted space environments so that leverage force can be effectively applied even though the applicable space available is restricted.
