| A link (10) of a chain conveyor has a plane (12) region terminating at at least one end thereof with an enlarged articulation element (13) projecting downwardly from the plane (12) and passed through by a hole (15) parallel to the plane (12) for the introduction of a pivot pin (11). The enlarged element (13) has at least at one end (17) close to the hole (15) opening, a plug (18) preventing the pivot pin (11) from slipping out of the hole itself. The plug (18) has facing parallel resilient arms (20, 21) terminating with undercut teeth (22, 23) projecting towards each other for fitting in corresponding rectilinear undercuts (29, 30) disposed parallelly on opposite sides of the enlarged element (13) close to the hole (15) opening. The plug (18) further comprises a projection (26) between said arms (21, 21) that is designed to be fitted in the pin-receiving hole (15) for preventing the plug (18) from sliding in at least one direction normal to the pin on fitting of the teeth (22, 23) in the corresponding undercuts (29, 30). | ||||||

| 185 | Modular plastic turn belt conveyor system, module, belt and drive therefor | US872524 | 1992-04-23 | US5217110A | 1993-06-08 | Michael L. Spangler; Thomas O. Perdue |
| A modular plastic conveyor belt with a plurality of modules with interfitting link ends, connected by pivot rods has a rod-retention system with a slidable pivot rod hole blocking member which is inserted from the bottom of the outermost link end of an edge module and is captured in the edge module after insertion while being slidable to blocking and nonblocking positions. The modules are constructed with wide link ends for driving and narrow link ends to create multiple shear planes on one side and constant width link ends on the other side of the module, the constant width link ends being spaced to accommodate the wide and narrow link ends and there being a connecting structure between the link ends for stiffening. | ||||||
| 186 | Conveyor chain assembly | US669195 | 1991-03-14 | US5096053A | 1992-03-17 | William G. Hodlewsky |
| The conveyor chain assembly is made of multiple rows of pivotally connected link modules. Each module has spaced link ends which project between the link ends of the module in the adjacent row. The joint between modules in a row is straddled or bridged by a module in the adjacent row to give a bricked lay-up. Each of the modules on the left side of the conveyor has a solid link end so the pivot rod abuts the inside of the link end. The other end of the pivot rod lies just inside of a spring plug mounted in the arm or link end on the right side module. The modules cannot be end-for-ended and assembled. They must be assembled correctly. Certain link ends are wider than the others to require proper assembly to the modules in the adjacent row and to distribute drive loads over a greater area. Both sides of the conveyor are essentially flush or smooth. | ||||||
| 187 | Removably retaining pivot rods in modular plastic belts | US610751 | 1990-11-08 | US5083660A | 1992-01-28 | Paul L. Horton |
| Headless pivot pins in flexible plastic modular belts for pivoting modular sections are desirable, but pose a problem in that they must be retained axially in place as the belt is loaded and used, generally under tension. This invention provides pivot pin retention means of low construction and installation cost by means of swivelling an interdigital belt module member, preferably of integrally molded plastic material, from a movable toe end to move about a swivel joint at an opposite anchored heel end out of its retention position blocking the pivot pin axial movement. One embodiment of the invention provides for swiveling of an end plate member at the edge of the belt in a plane normal to the belt and pivot pin axis forcibly away from a biased rest position at least partially covering a pivot pin aperture. Another embodiment positions a journalled post in a pivot pin aperture at the edge of the belt for removal by forcibly overcoming a resilient bias, preferably derived from characteristics and structure of the belt module plastic material, to move the journalled post out of the aperture so that the pivot rod can move out. Thus, headless pivot rods are employed without additional belt parts by manual actuation in assembling the belt or removing pivot rods in a simple manner that reduces belt material and assembly costs. | ||||||

| A conveyor belt composed of a plurality of interconnected modules, each of identical construction and end to end mateable. Each module includes a multiplicity of elongated parallel spaced link elements terminating in first and second link ends. An intermediate section between the link ends is of grid-like structure providing a box beam across the width of the module for structural strength. This intermediate section also includes angled surfaces which define sprocket recesses located midway between the pivot axes and which are adapted to mate with corresponding sprocket teeth of an associated sprocket wheel. These intermediate sprocket recesses provide the benefit of minimizing chordal action and scrubbing between the mating surfaces of the module and sprocket. | ||||||

| A plastic conveyor belt is formed of a plurality of non-reversible modules having inter-fitting link ends connected together and hinged by pivot rods having a rod capturing arrangement at each end of the outermost link ends of end module assemblies which is a blocking member insertable into a slot in the widest and outermost link end with the flat surface of the blocking member facing the rod and a projection for cooperating with the rod hole for holding the blocking member in place but allowing it to be removed. The belt also has internal modules in addition to end modules and all modules are constructed such that the narrowest link ends of unequal width link ends are adjacent sprocket cavities but are offset in a direction of another link end to provide additional strength and rigidity. | ||||||
| 191 | Ceramic conveyor belt connector rod end fixation | US380492 | 1989-07-17 | US4911681A | 1990-03-27 | William F. Funkhouser |
| A ceramic conveyor belt including a plurality of ceramic bars is disclosed. The bars have holes disposed through opposite ends, and are aligned to form a plurality of columns of bars. The columns are separated by ceramic spacers having corresponding holes. The aligned holes form a cross-passage through which a ceramic cross rod is disposed. An annular groove is disposed about the ends of the cross rod extending beyond the outer columns. A ceramic end tab includes a hole formed therethrough defined by a peripheral wall. A portion of the peripheral wall fits within the groove, leaving a space between the end tab and the groove on the opposite side of the end tab. A ceramic putty is disposed in the space, and hardens over a portion of the end tab, preventing radial movement of the end tab with respect to the rod, thereby preventing axial movement as well. Since the end tab is prevented from falling off the rod, the outer columns are securely held on the rods as well. | ||||||

| Conveyor belts are made from modular links having offset forward and rearward projecting eye parts to intercalate eye parts from one belt link between eye parts with oval lateral apertures. Connecting rods inserted through aligned apertures hingedly connect adjacent links. Clips restrict lateral turning of the belt links. Clips have general U-shapes with two legs, a bridge portion end, and opposite free ends. Projecting members at the free ends have lengths parallel to the legs and smaller than the lengths of the apertures in the belt links in which the clip is to be installed, and have heights equivalent to or smaller than the heights of the aperture in the belt link in which the clip is to be installed. The lateral distance between the two legs of the U, is larger than the lateral extent of an eye part in the belt link in which the clip is installed. | ||||||
