A target trap having a ratchet and pawl mechanism for partial recocking after a target has been thrown is disclosed. The trap includes a frame having a stationary ratchet wheel with contiguous ratchet teeth along a portion of the perimeter of the ratchet wheel. A biased pawl is mounted onto a throwing arm assembly for interacting with the ratchet wheel to hold the throwing arm assembly in a partially cocked position after the trap has been fired. The ratchet and pawl mechanism is arranged such that the throwing arm assembly can always be rotated in one direction so that an operator can move the throwing arm assembly into a cocked position. From the cocked position the throwing arm can move freely in the opposite direction to throw the target. After the target is thrown, the throwing arm recoils and rotates back in the one direction until the kinetic energy of the throwing arm is converted into potential energy in the spring, at which point the pawl engages the teeth of the ratchet wheel and prevents the throwing arm from rotating in the opposite direction. In this manner, the rotational momentum of the throwing arm assembly is used to partially recock the throwing arm for subsequent operations.
