A bowling alley pit assembly for transferring bowling pins and balls to a pin elevator and ball return includes a base member having a forward and rear portion and a pair of laterally-spaced walls. The base member is disposed in a pit area of the bowling alley with the forward portion adjacent to the pin deck and the rear portion adjacent a pin elevating mechanism. A pair of rollers are disposed between the spaced walls and a motor is operatively connected to one of the rollers. A pit-wide endless belt passes around the rollers for moving fallen pins rearwardly away from the pin deck. The pit assembly also includes a one-piece or unitary, generally hollow, plastic bounce board disposed between the upper and lower portions of the endless belt and between the pair of rollers. The bounce board is transverse to the alley and defines two side-by-side, relatively flat portions which slope downwardly to form a shallow trough with a recessed area at one end thereof. The bounce board also includes a plurality of reinforcing members therein which support the upper panel or surface thereof.
