Abstract: Piston rods (60, 62) of three linear hydraulic motors (36, 38, 40) are connected at their outer ends (64, 68) to two spaced apart transverse frame members (10, 12). A cylinder housing (72) is driven back and forth along each pair of piston rods (60, 62). Three transverse drive beams (48, 50, 52) are provided. Each drive beam (48, 50, 52) is directly connected to an associated one of the cylinder housings (72). Three sets of floor slat members (1, 2, 3) are provided. Each set (1, 2, 3) is connected to an associated one of the transverse drive beams (48, 50, 52). The linear hydraulic motors (36, 38, 40) are operated for moving the floor slat members (1, 2, 3) in one direction, for advancing a load, and for retracting them in the opposite direction. Each cylinder housing (72) has four fluid chambers (82, 84, 86, 88). The first and third chambers (82, 86) are interconnected and the second and fourth chambers (84, 88) are interconnected. This arrangement provides adequate force producting area with a relatively small diameter cylinder housing (72). Fluid passageways (110, 112) are formed in the piston rods (60, 62). Transfer valves (138, 140) and U-shaped tubes (134, 136, 126, 128) are clamped onto the outer end portions of the piston rods (60, 62) by means of a pair of clamp plates (190, 192, 214, 224) and interconnecting nut and bolt assemblies (194, 226).

Abstract: A plurality of drive motors are operated by fluid pressure for reciprocating the floor slats of a reciprocating floor conveyor. A switching valve alternately connects the forward and rear ends of the motors to pressure and return to reciprocate the slats. A forward and a rear control valve each has a closed position in which it blocks direct communication between the switching valve and all but one of the forward and rear ends, respectively. A four-way valve has ports communicating with pressure and return and with the pilot chambers of the control valves. The four-way valve connects one pilot chamber to pressure and the other to return to cause the conveyor to convey a load in a first direction. Reversal of the pressure and return to the pilot chambers causes a reversal of the conveying direction. At least one forward end and one rear end of the motors has an internal control valve positioned to open and close a connecting passageway between adjacent motor ends.

The cylinder housing (30) has end members (34, 36) through which piston rods (12, 18) extend. Four fluid chambers (52, 54, 56, 58) are formed within the linear hydraulic motor. Fluid chambers (52, 56) communicate with each other through conduits (62), and fluid chambers (54, 58) communicate with each other through conduit (64). Piston rods (12, 18) include conduits (68, 70) for fluid communication with chambers (54, 56). A snubber (74) is provided in the divider wall (46) of the cylinder housing (30). The snubber (74) reciprocates within the divider wall (46) and is adapted to abut the inner ends of the piston rods (12, 18) as the divider wall (46) approaches piston heads (16, 26) during the reciprocating process.

Abstract: The ball end (16) of the piston rod (14) of a linear motor (6) is mounted in a ball block (52). The block (52) has mating housing portions (54, 56) that abut along mating surfaces (64) that are substantially parallel to, but slope relative to, the motor axis (X). One housing portion includes an integral rear wall (70) through which the axis (X) extends and which defines a portion of a socket (58) that receives the ball end (16). The other housing portion has a flange (78) that projects into a space between the socket (58) and a sloping extension (74) of the wall (70). The outer surface (76) of the wall (70) is secured to a fixed support (84). The wall (70) transmits loads carried by operation of the motor (6) from the ball end (16) directly to the support (84) and minimizes loads on the fasteners (68) securing the housing portions (54, 56) together. The housing portion that includes the wall (70) is made from a material with a high load carrying capability. The other portion is relatively easy to machine and includes a passageway to deliver fluid to the ball end (16). A reinforcing bar (150) extends rearwardly from the motor (6) through a channel formed by a floor member of a reciprocating floor conveyor.

Abstract: A reciprocating floor (12) is provided at the bottom (22) of a container (10). The conveyor (12) may slope rearwardly from a front end to a rear end. A transverse liquid collection trough (30, 32) is provided at the rear end of the conveyor. Liquid in garbage or other material placed in the container (10) settles down onto the conveyor (12). This liquid is directed rearwardly along the conveyor to the trough (30, 32). It flows in the trough to an outlet (34, 34') which delivers it into a collection and holding tank (24). The tank (24) may include a plastic receptacle into which the liquid is collected.

Abstract: A plurality of piston heads (14, 16, 18) are spaced apart along the length of a single piston rod (12). A travelling cylinder body (20, 22, 24) is associated with each piston head (14, 16, 18). The traveling cylinder bodies (20, 22, 24) and the piston heads (14, 16, 18) define a first fluid chamber (92, 100, 88) on a common first side of the piston heads (14, 16, 18) and a set of second fluid chambers (96, 104, 90) on a common opposite side of the piston heads (14, 16, 18). A separate fluid supply and return tube (94, 102, 82) is provided for each first fluid chamber (92, 100, 88). The tubes (94, 102, 82) extend through the hollow interior (42) of the piston rod (12). A space exists in the hollow interior (42) between and around the tubes (94, 102, 82). This space serves as a supply and return passageway for all three second fluid chamber (96, 104, 90). Passageways (98, 106, 80) extend from interior space (42) to each of the second fluid chambers (96, 104, 90).

Abstract: A conveyor made up of a plurality of groups of floor members (10). Each group includes two movable floor members (1, 2) and a fixed floor member (F). The movable floor member (1 and 2) are moved in unison, from a start position to an advanced position. This moves a load (L) on the floor because the area of the moving floor members (1 and 2) is twice the area of the fixed floor members (F). When the movable floor members (1 and 2) reach their advanced positions, they are stopped. Then, the first floor members (1) are returned to their start positions while the second movable floor members (2) are held stationary. The load (L) does not move rearwardly because it is held by the stationary floor members (2) and the fixed floor members (F). Next, the second movable floor members (2) are returned to their start positions while the first movable floor members are held stationary. Again, there is no movement of the load (L) because it is held by the stationary floor members (1) and the fixed floor members (F). When the second movable floor members (2) reach their start positions, the sequence is repeated.

Abstract translation: 由多组地板构件（10）构成的输送机。 每个组包括两个可移动的地板构件（1,2）和固定地板构件（F）。 活动地板构件（1和2）从起始位置到前进位置一致地移动。 由于移动的地板构件（1和2）的面积是固定地板构件（F）的面积的两倍，因此将地板上的载荷（L）移动。 当可动地板构件（1和2）到达其前进位置时，它们被停止。 然后，第一楼层构件（1）返回到其起始位置，而第二可移动地板构件（2）保持静止。 负载（L）由于被固定的地板部件（2）和固定的地板部件（F）固定而不向后移动。 接下来，第二可移动地板构件（2）返回到其起始位置，同时第一可移动地板构件保持静止。 再次，由于固定的地板部件（1）和固定的地板部件（F）被固定，因此不存在载荷（L）的移动。 当第二可移动底板构件（2）到达其起始位置时，重复该顺序。
