| 198831000 | Upper and lower runs of same belt travel vertically aligned, laterally bending paths | 9 |
| 20080217139 | Curved Band Conveyor - The invention relates to a curved belt conveyor comprising: a supporting frame ( | 09-11-2008 |
| 20090000920 | Curved Conveyor with Guide for Preventing Radial Belt Migration - A curved conveyor comprises a toothed, endless belt and a slider bed that supports a portion of the belt. The slider bed can include at least one guide in the form of a rail extending along the slider bed in the direction of belt travel. Each of the belt teeth are discontinuous and have at least one gap sized to receive the at least one guide; thus, the at least one guide prevents inward radial migration of the belt during movement of the belt. The conveyor can further comprise a center guide wheel or a guide post to prevent belt radial migration. | 01-01-2009 |

| 20090260957 | Low friction roller belt - A modular conveyor belt having longitudinal grooves on the top and bottom of the belt. Pairs of rollers are installed between the links within these grooves such that the rollers do not project over the surface of the belt but are completely integrated into the body. The rollers may be installed directly onto the pivot rods. The belts are supported by rails that enter into the longitudinal grooves to engage with the rollers to carry the belt as it moves. The grooves on the bottom side of the single modules are curved in such a way that the slots form a circle when the belt moves around a sprocket. This configuration allows for steel disks to be installed between the sprockets on the driving and idling shaft. The disks help to support the belt and to improve smooth running of the belts around the sprocket under a high load by taking the radial forces acting when the belt is under high tension. | 10-22-2009 |
| 20090301844 | Device for and Method of Sampling the Amount of Carryback Material Transferred by a Bulk Material Belt Conveyor System - An assembly comprises a bulk material belt conveyor system and a carryback sampling device. The bulk material belt conveyor system comprises a belt and a structural frame. The belt is supported by the structural frame and has a downwardly facing portion. The belt is configured to traverse relative to the structural frame. The carryback sampling device comprises at least a first support member, a carryback receptacle, and a carryback scraper. The first support member is pivotally attached to the structural frame about an axis. The carryback scraper and the carryback receptacle are attached to the structural frame via the first support member in a manner such that pivotal movement of the first support member about the axis relative to the structural frame brings the carryback scraper into engagement with the downwardly facing portion of the belt with the carryback receptacle positioned therebeneath. | 12-10-2009 |
| 20100122894 | CURVED BELT CONVEYOR - Roller-guided conveyors are described herein. An example roller-guided conveyor comprises a first holder and a second holder and a first guide roller and a second guide roller. The first guide roller has a first axis of rotation and pivotally coupled to the first holder about a pivot axis that is eccentric relative to the first axis of rotation. The first guide roller is spaced a distance from the second guide roller to guide a conveyor belt therebetween. | 05-20-2010 |
| 20110120838 | BELT CONVEYOR - The invention relates to a belt conveyor which comprises a conveyor belt ( | 05-26-2011 |
| 20140262694 | CONVEYOR HAVING A CATENARY IN THE RETURN PATH - Curved conveyors are disclosed herein. An embodiment of a curved conveyor includes a first end and a second end. Items to be conveyed are received onto the conveyor at the first end and the items to be conveyed are removed from the conveyor at the second end. The conveyor forms an arc between the first end and the second end. A continuous belt rotates between the first end and the second end along the arc of the curved conveyor. The belt has a forward path during its travel from the first end to the second end and a return path during its travel from the second end to the first end. A chain is attached to the belt wherein the chain forms a catenary in at least a portion of the return path. | 09-18-2014 |
| 20140367228 | CONVEYOR ASSEMBLY AND ASSOCIATED METHOD - A curved conveyor assembly includes a frame that defines a curved conveyance path. A conveyor belt is positioned on the frame system for travel along the curved conveyance path. At least one hold down guide is mounted to the frame and manually movable between an operating position and an access position. In the operating position a retaining lip of the hold down guide extends into the curved conveyance path proximate an edge of the conveyor belt for limiting upward movement of the edge of the conveyor belt. In the access position the retaining lip is moved away from the edge of the conveyor belt. | 12-18-2014 |
