Abstract: An end of stroke cushion for a linear hydraulic motor. A piston-cylinder unit includes a cylinder body (42) reciprocally slidable on a piston rod (40) having a piston head (64) which defines working chambers (82, 84) within the cylinder body (42). The piston rod (62) is tubular and includes a plurality of sidewall ports (P1-P7). A radially-expandable annular valve ring (106) normally snugly surrounds the piston rod (62) and during axial movement of the cylinder body (42) relative to the piston rod (62), the valve ring (106) will move axially relative to the sidewall ports (P1-P7) in the piston rod (62). Pressure introduction to the working chamber (84) through the sidewall ports (P1-P7) of the piston rod (62) and against the valve ring (106) radially expands the valve ring (106). This allows oil flow to move into the working chamber (84) such that when the chamber (84) expands, the cylinder body (42) and valve ring (106) will move axially relative to the sidewall ports (P1-P7), successively uncovering the ports (P1-P7) during movement. Removal of fluid from the working chamber (84) will cause oil movement out from the chamber (84), through the sidewall ports (P1-P7) into the tubular piston rod (62) such that when the linear motor (10) approaches the end of its stroke, the valve ring will close the sidewall ports (P1-P7) in the piston rod (62) which allows oil flow out from the working chamber (84) in succession.

Abstract: In a reciprocating floor conveyor, elongated inflatable seal members (44, 44') are positioned to seal the gaps (60) between adjacent floor members (16, 16'). A base portion (52, 52') of each seal member (44, 44') is received within a base channel (46, 46') which is formed in a side portion (18) of a floor member (16). Side portion (18) includes a second channel (50, 50') in which a sealing portion (54, 54') of the sealing member (44, 44') is situated. The second side (20, 20') of each floor member (16, 16') includes a third channel (58, 58') which extends longitudinally of the floor member (16, 16') and confronts the sealing portion (54, 54') of the adjacent floor member (16, 16'). When the inflatable portion (54, 54') of the seal member (44, 44') is inflated, it extends into and contacts the inner surface of the third channel (58, 58'). When the sealing portion (54, 54') is deflated, it folds onto itself (FIGS. 11 and 13) and moves away from sealing engagement with the inner surface of channel (58, 58').

Abstract: A plurality of piston heads (P1, P2, P3) are spaced apart along the length of a single piston rod (R). A separate traveling cylinder body (CB1, CB2, CB3) is associated with each piston head (P1, P2, P3). The traveling cylinders bodies (CB1, CB2, CB3) and the piston heads (P1, P2, P3) define first fluid chambers (1A, 2A, 3A) on a common side of the piston heads (P1, P3, P3) and a set of second fluid chambers (1B, 2B, 3B) on a common opposite side of the piston heads (P1, P2, P3). A separate fluid supply and return passageway is provided within the piston rod (R) for each of the working chambers (1A, 1B, 2A, 2B, 3A, 3B). Center members (C1, C2, C3) are secured within the hollow interior of the piston rod (R) and serve to divide the hollow interior into four axial sections (122, 124, 126, 128). The piston rod (R) includes first and second end members (RE1, RE2). The first end member (RE1) includes outer end ports (P1A, P1B, P2A) for the fluid delivery and return passageways for three of the working chambers (1A, 1B, 2A). End member (RE2) includes outer end ports (P2B, P3A, P3B) for the fluid delivery and return passageways for the remaining three working chambers (2B, 3A, 3B). The fluid delivery and return passageways are defined in part by concentric tubes (118, 120, 70, 66) located within piston rod (R) and the inner spacces (122, 124, 126, 128). The control system for transmitting fluid pressure to and from the working chambers (1A, 1B, 2A, 2B, 3A, 3B) includes sequencing valves which are separate units from the piston rod (R), the piston heads (P1, P2, P3) and the cylinder bodies (CB1, CB2, CB3). The sequencing valves are positioned to control the delivery of pressure fluid into the working chambers (1A, 1B, 2A, 2B, 3A, 3B).

Abstract: A plurality of floor members (40, 58, 106) are supported on guide beams (16, 18, 60, 102). The guide beams (16, 18, 60, 102) are spaced apart such that the floor members (40, 58, 106) have spaces between their side portions. The guide beams (16, 18, 60, 102) have oppositely directed flanges (26, 78, 80, 112, 114) secured to their tops. Bearing members (30, 116) slip over these flanges and rest on top of the guide beams (16, 18, 60, 102). Bottom members (20, 64, 98) extend laterally between the guide beams (16, 18, 60, 102), to form channels in the regions between the floor members (40, 58, 106). In one embodiment, refrigerated air is directed through these channels. In a second embodiment, the channel is used to collect small particles of ice and ice water. In a third embodiment, garbage is allowed to enter into the channel space. The sidewalls (108, 110) of the floor members (106) engage this garbage and move it when the floor members (106) are moving and hold it when the floor members (106) are stationary. The floor in which refrigerated air is circulated through the channels, and the floor in which small ice particles and ice water are collected in the channels, is set on an insulated base. The garbage conveying floor may be set on an incline, for lifting garbage up from a lower level to an elevated level above the open top of a container (92) provided for collecting the garbage (96).

Abstract: Piston rod portions (83, 85, 87) of three linear hydraulic motors (10, 12, 14) are connected at their opposite ends to two spaced apart transverse frame members (88, 90). A cylinder (120) is driven back and forth along each piston rod (83, 85, 87). Three transverse drive beams (16, 18, 20) are provided. Each drive beam (16, 18, 20) is directly connected to an associated one of the cylinders (120). 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 (16, 18, 20). The linear hydraulic motors (10, 12, 14) are operated for moving the floor slat members in one direction, for advancing a load, and for retracting them in the opposite direction.

Abstract: A floor member (10) of channel form is pushed downwardly to install it onto bearings (72) and hold down members (16) which were previously installed on longitudinal guide tubes (12) which extend in the same direction as the floor members (10). The bearings (72) have sidewall portions which slope downwardly and outwardly to lower edge (96, 98). These sidewalls (76, 78) are connected at their upper portions to the bearing (72) in such a way that they will flex inwardly, into spaces (112, 114) provided for them, in response to a downward "snap on" movement of the floor members (10). The hold down members (16) have hold down wings (50, 52) which slope downwardly and outwardly to lower edges (54, 56). The hold down wings (50, 52) also flex inwardly, into spaces provided for them, in response to a downward "snap on" movement of the floor member (10). Any upward force applied on an installed floor member (10) will move inner edge portions (28, 30) of its bottom flanges (24, 26) into contact with the lower edges (54, 56) of the hold down wings (50, 52) of the hold down member (16). The hold down member (16) in effect functions to connect the longitudinal guide beam (12) to the floor member (10), so that the stiffness of the longitudinal guide beam (12), and its connection to other frame members (14) will help resist upward movement of the floor member (10) off from its support.
