Abstract: Shown is a direction control valve (16) for use in a hydraulic control system having a source of hydraulic pressure (P) and a return passageway (50). The control valve includes a first hydraulic flow pathway (140, 142) and a second hydraulic flow pathway (144, 146). A two-position valve (38) includes four ports (48, 58, 64, 74). First and second pilot-operated poppets (88, 90) each have a pilot chamber (84, 86). When the valve (38) is in its first position, the source of hydraulic pressure (P) is provided to the pilot chamber (86) of the first poppet (88) and the pilot chamber (84) of the second poppet (90) is connected to the return pathway (50). As a result, one hydraulic flow pathway (140, 142) is open and the other hydraulic flow pathway (144, 146) is closed.

Abstract: A replaceable wear plate assembly for a reciprocating floor conveyor that includes a plurality of elongated slat members (12) mounted adjacent each other in a common plane. A replaceable wear plate (42) is provided for each slat member (12) of the reciprocating floor conveyor. The slat members are formed with a ridge (28, 30) and inwardly projecting lip (32, 34) extending along the side edges of each slat member. The ridge and lip portion form a slot (36, 38) along the side edges of the slat members for receiving the side edges of the replaceable wear plates. The ridge and lip portion and the edges of the wear plates form a tongue and groove arrangement whereby the movement of the wear plate is restricted sideways and in a vertical direction. A connector (48) is provided to secure each wear plate to its slat member in order to restrict movement of the wear plate longitudinally along its length.

Abstract: An internal check valve for use in a linear hydraulic motor in the form of a piston-cylinder unit including a cylinder body (38) reciprocally slidable on a piston component (40). The piston component (40) includes a tubular piston rod (52) and a piston head (60) defining first and second working chambers (136, 140) within the cylinder body (38). The tubular piston rod (52) includes a center tube (102) located within the piston rod (52). The center tube (102) provides a fluid passageway (134) through its center which communicates with a first working chamber (136). An annular second passageway (142) is formed by and radially between the piston rod (52) and the center tube (102). A spring biased check valve (116) is positioned within the piston rod (52, 54) and is operatively connected with one of the passageways (134, 126, 130). The check valve (116) has a valve member displaceable from a valve seat (120) by hydraulic pressure to overcome the spring bias (122, 124) and allow flow in one direction. The center tube (102) is axially displaceable relative to the piston rod (52). Displacement is effected by end of stroke movement of the cylinder body (38) and displacement of the center tube (102) causes displacement of the valve member (116) to mechanically open the check valve.

Abstract: A wide floor member (10) is supported by slide bearings (18) which are located on a pair of spaced apart guide beams (12). The floor member has opposite side portions, each of which includes a top portion (38, 40). A liquid collecting channel (46) is located between the top portions (38, 40). Liquid in garbage or some other material which is supported by the floor drains into the channels (46). This liquid flows to a transverse collection trough (94) having an outlet (96). The liquid flows through the outlet (96) into a tank (88). A pump (98) may pump the liquid back onto the material within the container (74).

Abstract: A bulk material such as garbage is introduced into a hopper inlet (14) of a compactor (12). A piston (18) in the compactor moves the bulk material out from the compactor (12) inot a vault (26). In the vault (26) the material is compacted against a barrier wall (66) until an initial body of compacted material is formed between the intlet and the barrier wall (64). Then, the barrier wall (64) is retracted up into a position substantially within the plane of the top wall (32). Then, the compactor (12) is operated to compact additional bulk material (24) into the vault (26), and at the same time move the material (24) lengthwise through the vault (26). When the vault (26) is sufficiently full of compacted material (24), the vault (26) is expanded for the purpose of enlargening the cross sectional dimension of its inner space. A cargo receiving compartment (30) of a road vehicle (10) is positioned in registry with the outlet of the vault (26). Reciprocating floor conveyors (RF1, RF2) in the vault (26) and the cargo receiving compartment (30) are operated together for moving the body of compacted material (24) out from the vault (26) into the cargo receving compartment (30) of the road vehicle (10).

Each floor member has first and second sides (14, 16), each of which may include a longitudinal dovetail groove (24, 56). A first resiliently bendable elongated elastomeric seal (26) is provided for each floor member (10). The first seal (26) has an inboard base portion (28, 50) captured within the first side's dovetail groove (24) and an outboard portion which includes a branch strip (52) extending from the inboard portion (28, 50). The branch strip has a free edge (44, 54) positioned to contact a confronting surface (16) of an adjacent floor member (10) and has a stiff resiliency urging its free edge (44, 54) toward the confronting surface (16). A second bendable elongated elastomeric seal (58) may be provided. The second seal (58) has a retaining base portion (60) formed at a first edge thereof and extends generally upwardly therefrom to a second outer edge (68). The retaining base (60) is shaped to be engaged within the second side's dovetail groove (56) such that the second seal (58) is bendable from a position where it is extending generally outwardly from the second side (16) to a position substantially parallel to and adjacent the second side (16). The outer edge (68) is positioned to contact a confronting surface (14) of an adjacent floor member (10) above a dovetail groove (24) formed in the adjacent floor member's first side (14).

Abstract: Plug-together joints are formed between floor members (10, 10') and drive beams (18, 18'). These connections may comprise a pin or insert (72) secured to the drive beam (18) and a box or socket (52, 54) secured to the floor member (10). Or, it may comprise a box or socket (176, 178) secured to the drive beam (18') and an insert or pin (188) secured to the floor member (10'). The plug-together connection is used in a reciprocating floor conveyor of a type having slide bearings (122) for the floor members (10, 19') which allow the floor members (10, 10') to be snapped into place from above. The floor may also include hold down members (90) which are secured to the guide beams (14) for the floor members (10, 10') and which are also constructed to allow the floor members (10, 10') to be snapped into place from above. The hold down members (90) include hold down wings (100, 102) which, when the floor member is in place, locate lower edges (104, 106) above inner edge portions (84, 82) of the floor member (10, 10'). This puts the hold down wings (100, 102) into positions to block upward movement of the floor members (10, 10').

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 producing area with a relatively small diameter cylinder housing (72). Fluid passageways (110, 112) are formed in the piston rods ( b 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).
