A "Flask and Pattern Starter" device, for the purpose of providing a seal-breaking movement of the cope flask and for the matchplate pattern also, as a molder "squeezer molds" in a foundry operation where he is lifting a flask, and a pattern. The apparatus serves as a leverage surface for the hands of the molder as he separates the pattern from cope and drag flasks in a molding operation. The device is placed over guide pins which are normally used on pattern equipment in the foundry operations.
