Patent abstract
Improved slide lock apparatus used in bending apparatus to bend stock to an acute angle. A hydraulic cylinder with a ram extendable under hydraulic pressure provides the bending power. The ram automatically retracts a slide from an first outward location when hydraulic pressure is removed to a second inward location for two separate bends to achieve an acute angle bend. This improved slide lock prevents any possible injury to the operator by covering a stop arranged to prevent the slide from moving outward a greater distance then the first outward location.
