| 202 | Folding apparatus for transporting particulate material | US619183 | 1996-03-21 | US5662210A | 1997-09-02 | Robert J. Toews |
| A conveyor for particulate material of the type including a tube with a belt running through the tube and defining a return run of the belt outside the tube provides a folding action by which the length of the tube can be reduced by folding an upper portion back against a lower portion. The folding action is actuated by a hand crank which drives a chain wheel connected to a pivot pin carrying the upper portion. The pivot pin is mounted to one side of the tube which is opposite to the return run of the belt. In order to provide an extension portion of the return run which can be released to provide the length necessary for the folding action, the return run passes over a pair of rollers to form a serpentine section of the return run at the fold line of the tube. Each of the rollers is carried on a respective one of the upper and lower portions on opposite sides of the fold line to release the serpentine portion as the folding action is effected. | ||||||
| 203 | Construction conveyor belt | US274202 | 1994-07-12 | US5511652A | 1996-04-30 | Terry W. McGinnis |
| An improved conveyor belt construction includes lateral edges which fold upwardly and inwardly upon the application of longitudinal directed tension. The tendency of the lateral edges of the belt to curve upwardly and inwardly, coupled with the presence of locked plates, enable the belt to form a series of completely enclosed box-like structures which can move powdery ash-like materials with ease. The construction includes five layers, two of which are reinforced with reinforcing cords laid at differing angles. | ||||||

| A belt conveyor comprises an endless belt (1) with two force-absorbing members (2, 3) extending throughout the entire length of the belt. These members are each connected to a respective edge portion of the belt and project from the same side of the belt when this is the straightened state. Support rollers are disposed for supporting the belt along at least a part of the conveying path. Each force-absorbing member (2, 3) is connected to it belts edge portion via a hinge portion enabling said member to turn through about .+-.90.degree. relative to said belt edge portion for guiding the belt about a deflecting roller (13) whose axis (14) is substantially perpendicular to the plane of the adjacent conveyor belt part, the two force-absorbing members being turned in the same direction relative to the respective belt edge portion and located at substantially the same distance from the axis of the deflecting roller. | ||||||
| 209 | Belt heater for conveyors | US423014 | 1989-10-18 | US5024319A | 1991-06-18 | Steven C. Dixon; James W. Dixon |
| A conveyor belt is provided for carrying granular coal or ore from a mine or a crushing station, together with a belt heater in the form of a fuel burner which turns on to melt ice which as formed on the belt at temperatures below freezing. The belt heater heats the conveyor belt surface to a temperature sufficient to melt the ice film to form water and thereby prevent the granular coal or ore from sliding to impair the conveying operation of the conveyor belt or to cause spillage from the conveyor belt. When the conveyor belt stops, the fuel burner stops and thus prevents damage to the conveyor belt. A preferred fuel burner is an oil heater. An infrared heater can also be used but a fuel burner is preferred in flame contact with the belt. The flame of the fuel burner when used in direct contact with the conveyor belt can be immediately shut off when the conveyor belt stops and thereby prevents damage to the conveyor belt. The flame temperature or air temperature reaches a value of at least about 400.degree. C., preferably about 450.degree. C. to 850.degree. C. An electrical system is provided to shut down the fuel burner as soon as the conveyor belt stops. Belt heater is useful even if no ice film is formed on the conveyor belt by heating the hinge or fold area of the folding conveyor belt. An oil burner housing is provided with an air access door to permit debris dropping from the conveyor belt near the flame to be removed. | ||||||

| A tubular belt conveyor has an endless belt having a substantially flat cross-section with constant thickness over the breadth thereof. The belt is deformed over its breadth in a curved fashion such that the longitudinal side edges of one surface are brought into abutment with each other thus forming a tube, with the adjacent edges constituting a longitudinal lug projecting radially outwardly from the tube portion. The lug is clamped and held on both sides by a pair of guide rollers and pressed at its radially outer end surface by a pressing roller. The tubular form of the belt is maintained by a plurality of tube-forming rollers surrounding the tube portion of the belt. The flat belt is easy to produce and can be coiled in a compact manner for easy packaging. Local wear of the belt due to contact with the axial end edges of the pulley is avoided because the pulley at each end of the conveyor may have an axial length greater than the breadth of the belt, because of the flat cross-section of the belt. | ||||||

| A conveyor for transporting bulk material mainly underground along a closed path traversing at least one loading or unloading zone has a mainly one-level track on the path. This track has a one-level main rail following the path outside the zone and having ends at the zone, respective one-level Y-intersections at the zone each having a central leg connected to the respective rail end and right and left arms extending into the zone, and respective right and left rail branches at the zone extending from the right and left arms of the one Y-intersection to the right and left arms of the other intersection and spaced apart transversely of the path. An endless conveyor belt extends along the path and through the zone and has right and left longitudinal edges. Respective endless rows of longitudinally spaced right and left trucks alternate with one another along the path and each have a lower end attached to the respective belt edge and an upper end riding on and displaceable longitudinally in the main rail. An endless and flexible tension-transmitting drive element extends along the path and through the zone and is connected at least indirectly to the belt and trucks. A drive connected to the drive element advances the belt and trucks along the path in a transport direction. A deflector at the upstream Y-intersection forces the right trucks into its right arm and then into the right branch and forces the left trucks into its left arm and then into the left branch. The belt is closed and tubular outside the zone when its right and left trucks are all in the main rail and is open in the zone when the right trucks are in the right branch and the left trucks are spaced therefrom in the left branch. | ||||||
| 213 | Method and device for preventing a flexible tubular belt from twisting for use in a tubular belt conveyer | US269479 | 1981-06-02 | US4402395A | 1983-09-06 | Kunio Hashimoto |
| A method and device for preventing a flexible tubular belt from twisting for use in a tubular belt conveyer are disclosed. A flexible tubular belt is extended between first and second rollers, positioned at a certain distance away from each other, on which the tubular belt is opened, and the belt moving between the two rollers in the tubular form is supported by sets of support rollers which are radially arranged around the peripheries of the belt in contact therewith and are rotatably mounted to support frames. Twisting of the belt is prevented by means which varies an angle of a correction roller extending in a direction substantially perpendicular to the direction of movement of the belt in contact therewith. The correction rollers may be disposed in contact with the bottom and/or sides of the belt. | ||||||

| A conveyor belt supportable on troughing rollers for conveying bulk material. The belt is capable of sharp lateral curves and includes a main body section with an embedded, central, inextensible, flexible spine formed of cables. Corrugations extend outwardly to the edges from the central section of the body. The central section of the body is rectangular in cross section and constitutes the majority of the belt. The belt is molded flat and has layers of cords or strands, of inextensible material such as wire, embedded therein from edge to edge. The layers are parallel to each other and to the surfaces of the belt adjacent the edges and adjacent the central portion of the body. Along the lines where the corrugations meet the central portion, the layers are positioned closer to each other to thereby define hinges for bending of the belt longitudinally to thereby permit troughing of the belt during the conveying of bulk material. | ||||||
