ABSTRACT:
A group of six floor slat members (FS1-FS6) are staggered in position relative to each other. Each is first advanced and then returned by a linear hydraulic motor (M1-M6). Each motor (M1-M6) is provided with a two position directional valve (DV1-DV6). A mechanical connection (56, 58, 60, 62, 66, 68) is provided between one floor slat member (FS1) and a pilot valve (PV1) for the directional valve (DV1), for the motor (M1), and for the first floor slat member (FS1). This mechanical connection and the pilot valve (PV1) function to switch the position of directional valve (DV1) at the end of each advance and return stroke of the floor member (FS1). During the return stroke, the motor (M1) is connected to a pump (P2) designed to return the floor slat member (FS1) within the same amount of time as the floor slat members (FS1-FS6) advance a distance equal to the stagger distance. During its advance, the first floor slat member (FS1) moves an operator (56, 30, 31, 32) of a pilot valve (PV2) and as such operator moves it functions to successively communicate pressure to the directional valves (DV2-DV6) for the remaining floor slat members (FS2-FS6). Delivery of pressure fluid to a directional valve (DV2-DV6) operates to shift the valve in position, from its advanced position to its return position. This occurs substantially at the end of the advance stroke of each floor slat member (FS2-FS6).
