Abstract: A reciprocating floor conveyor comprising a support frame (12), a plurality of elongated conveyor slats (?), a plurality of drive motors (40), one for each conveyor slat, for reciprocating the conveyor slats, and a set: of lugs (86,100) and contact blocks (90) for maintaining contact between the drive motors (40) and conveyor slats (CS) should the conveyor slats move relative to the drive motors. The drive motors are mounted on the support frame beneath the conveyor slats. Each conveyor slat (CS) and drive unit (40) includes a set of longitudinally-spaced lugs (86,100). The conveyor slat lugs and drive unit lugs are alternately spaced apart in substantial longitudinal alignment. A set of contact blocks (90) is provided for each drive unit. Each contact block (90) is positioned between and in engagement with an adjacent pair of conveyor slat and drive unit lugs. Each contact block is movable toward and away from a conveyor slat. As the drive motors reciprocate the conveyor slats, should a conveyor slat move relative to its drive unit, the contact blocks move to maintain engagement between the contact blocks and adjacent conveyor slat and drive unit lugs.

Abstract: The piston rods (10, 12, 14) of three linear hydraulic motors (M1, M2, M3) are stationary and include fluid pressure passageways (40, 52, 42, 54, 44, 56) which direct fluid pressure into and out from working chambers (16, 34, 18, 36, 20, 38) on opposite sides of piston heads (22, 24, 26). Movable cylinder barrels (16, 18, 20) are connected to a load, e.g. floor members (FM1, FM2, FM3) of a reciprocating floor conveyor (FIG. 18 ). The outer ends of the piston rods (10, 12, 14) include balls and the balls include ports (46, 58, 48, 60, 50, 62) through which fluid pressure is delivered or removed. Associated with each port is a limit valve LV1, LV2, LV3, LV4, LV5, LV6. Limit valves (LV1, LV2, LV3) are pushed into an open position by a retraction of the motors (M1, M2, M3). Limit valves (LV4, LV5, LV6) are pulled into an open position by extension of motors (M1, M2, M3). The limit valves (LV1, LV2, LV3, LV4, LV5, LV6) include springs biasing them into closed positions. The push and pull forces are in a direction opposite this spring force. Limit valves (LV1, LV2, LV3, LV4, LV5, LV6) are also opened by line pressure when flow is in a direction opposing the spring force. The system includes a two position switching valve (SV) controlled by a two position pilot valve (PV). The system operates to move the motors (M1, M2, M3) in unison, in a first direction, and to retract them sequentially. The system is reversible.

Abstract: A primary valve orifice (26) divides a check valve cavity into first and second portions (4, 6). A valve member (34) closes the orifice (26) in response to higher pressure in the first portion (4) and is unseated to open orifice (26) in response to higher pressure in the second portion (6). An axial passageway (44) extends through the valve member (34). A control rod (50) extends into the cavity (4, 6) and through the passageway (44). The rod (50) carries a secondary valve plug (52) that is biased by a spring (60) to close one end of the passageway (44), and a pull block (78) that engages the opposite end of the valve member (34). A stem (40) extends from the valve plug portion (36) of the valve member (34) through the orifice (26) and is telescopically received in a sleeve (62). The control rod (50) is pulled to cause the secondary valve plug (52) to unseat and the pull block (78) to engage the sleeve (62). This opens the passageway (44) to equalize pressure on the two ends of the valve member (34). Further movement of the control rod (50) moves the valve member (34) and sleeve (62) as a unit to open the orifice (26). The sleeve (62) may be omitted, with the pull block (78) directly engaging the valve member (34).

Abstract: In a reciprocating floor conveyor, a plurality of longitudinal base sections (16) are connected together to form a support and guide structure for the floor members (10). The base structure comprises a plurality of guide beams (18 and 20, 22) which extend longitudinally of the conveyor, and liquid collection channels (14) between adjacent floor members (10). Each floor member (10) is supported on and by an adjacent pair of guide beams (18 and 20, 22). Snap-on bearings (76) are provided, which include cam portions for aiding their snap-on installation onto a top portion (24, 26, 28) of a guide beam (18). The bearings (76) include look flanges (86, 88) which serve to hold the floor members (10) in place. Each floor member (10) includes a pair of outside walls (112, 114) having inwardly directed lips (120, 122) which confront lower edge portions (102). Each floor member (10) also includes a pair of inside Walls (116, 118) having a two stage lock. Inside Walls (116, 118) include laterally inwardly directed shoulders (127, 130) which are at the same level as the lips (120, 122). They also include lips (128, 132) at a lower level. The shoulders (127, 130) and lips (128, 132) are positioned to engage the lower edge portions (104) of lock flanges (88) on the bearings (76). The base sections (16) are connected together in the top regions of certain guide beams (20, 22). Each base section (16) includes on one side a groove portion (34) of a tongue and groove joint. On its opposite side it includes a complimentary tongue portion (40) of the joint. The tongue portion (40) of each base section (16) is united with the groove portion (34) of the adjacent base section (16). The components of the joint are constructed to provide an elongated seal strip chamber in the joint when the tongue portion (40) is within a groove portion (34). An elongated seal member (60) is located within this chamber (54). The seal member is compressed and makes tight contact with both a surface of the 35 groove component (34) and a surface of the tongue component (40).

Abstract: In a housing, there is formed, in series, a first end cavity, a first cylinder cavity, a pressure cavity, a second cylinder cavity and a second end cavity. The cavities are separated by walls which include orifices. Two identical valve members are located in the housing. The first valve member has a piston and a valve plug in the first end cavity and a valve plug in the pressure cavity. The second valve member has a piston and a valve plug in the second end cavity and a valve plug in the pressure cavity. Pressure in the pressure cavity acts on the confronting ends of the two valve members. A two position control rod, in a first position, connects pressure to the piston in the first end chamber and connects the second end chamber to return. The piston has a larger area than the second end of the valve member, creating a force differential which moves the first valve member endwise inwardly. Pressure acting on the second end of the second valve member moves it endwise outwardly. The same control rod, in its second position, connects the second piston with pressure and the first piston with return. Pressure acting on the second end of the first valve member moves it endwise outwardly. Pressure acting on the second piston moves the second valve member endwise inwardly. Such movement of the valve members moves the valve plugs to open and close orifices in the separator walls, to switch pressure and return between two paths leading from the valve assembly.

Abstract: An elongated seal strip (38) is provided between adjacent floor slat members (10, 10', 10") in a reciprocating floor conveyor. The seal strip (38) includes an inboard base (40) which is received in a sidewall groove (30) and an outboard portion (42) which extends laterally outwardly from the groove (30). The outboard portion (42) is composed of a first layer (46) joined to a second layer (48), such as by co-extrusion. The first layer (46) is a relatively hard material with good wear characteristics and a low coefficient of friction. The second layer (48) is a softer but more resilient material. The combined thickness of the two layers (46, 48) is greater than the gap width between adjacent floor slat members (10). As a result, the resilient (48) must be compressed in order to install the outboard portion (42) of the seal strip (38) into the gap between adjacent floor slat members (10). During use, the layer (48) provides a resilient backing for the layer (46), continuously urging it into sealing contact with the confronting side surface of the adjacent floor slat member. The resilient layer (48) continuously changes in thickness to accommodate for changes in the gap width, caused by the relative movement of the floor slat members (10) to each other, for whatever reason.

Abstract: A bulk material such as garbage is introduced into a hopper inlet (14) of a comparator (12). A piston (18) in the comparator moves the bulk material out from the comparator (12) into the 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 inlet 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 comparator (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 receiving compartment (30) of the road vehicle (10).

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).

Abstract: Generally horizontally disposed bracing trusses (44, 46) are interconnected between the bottoms of the longitudinal drive beams (70, 72, 74) and the bottoms of the associated transverse drive beams (100, 102, 104), within a reciprocating floor conveyor. This and other reinforcement particularly adapts the system for use in a stationary installation having a relatively wide floor. Trucks (RV) equipped with reciprocating floor conveyors are backed into a receiving house (H) and the conveyors are used for unloading bulk material (B) from the trucks (RV) into the receiving house (H). The bulk material (B) is conveyed from the receiving house (H) up to an elevated inlet (16) at one end of an elongated enclosure (E). The enclosure (E) includes a reciprocating floor conveyor (24) at its bottom and an elevated screw conveyor (36) at its top. The reciprocating conveyor (24) is operated to move bulk material out from the enclosure (E) at a controlled rate. The elevated screw conveyor (36) is used for rapidly distributing additional bulk material (B) that is being added at the elevated inlet (16) and the trailing portion of a previous deposit of the bulk material (B') which has been moved away from the elevated inlet (16) by the reciprocating floor conveyor (24).

Abstract: Reciprocating floor conveyor floor members (28) are moved by hydraulic cylinders (1, 2, 3) which are slightly tilted so as to exert a vertical component of force onto the ends of longitudinal drive beams (128, 130, 132) to which the cylinders (1, 2, 3) are connected. These beams (128, 130, 132) are made from tubular stock. Each is guided by a pair of longitudinally spaced apart bearings. Each bearing is a part of a bearing assembly (128, 130) which depends from an upper central portion of a transverse truss (80, 82). Each longitudinal drive member (128, 130, 132) is welded to a transverse drive beam (10, 12, 14) by fillet welds on each side of the longitudinal drive tube (128, 130, 132). Each such drive tube (128, 130, 132) is stiffened in the region of the weld by a short tubular insert which is rammed into the drive tube. The floor members (28) of the conveyor run on plastic slide bearings (26) which are snap fitted onto longitudinal guide beams (22). The guide beams (22) are small in size and are welded on both sides to transverse support beams (24). The construction of the slide bearings (26) permits the use of large dimension, strong, undressed fillet welds. The slide bearings (26) include wing portions (68) on each side which abut similar wing portions (68) on sideways adjacent bearings (26). The floor members (28) are held vertically relative to the bearings (26) by the engagement of bottom flanges (36, 38) within side slots (72) formed in the bearings (26). The floor members (28) add strength and stiffness to the bearings (26) and the abutting contact of the wing portions (68) causes the bearings (26) to mutually brace each other.
