In shearing apparatus comprising a fixed and a movable shear element for shearing work such as wire into desired lengths, a stop member is provided for stopping the wire as same is fed endwise through the fixed shear element. Each time the wire length projecting out of the fixed shear element is cut off, the stop member is pivoted against the force of a spring to relieve the impact of the shearing operation exerted thereon. For adjustably moving the stop member toward and away from the fixed shear element, the stop member is mounted on a carriage having a tapped hole through which extends a threaded first shaft geared to a second shaft. This second shaft can be rotated manually for moving the carriage toward or away from the fixed shear element and can be locked in a desired angular position by a locking pin which is spring biased into engagement in any of several circumferentially spaced indentations formed in a collar on the second shaft.
