| 221 | CONVERTING A PRE-EXISTING CONVEYOR FRAME INTO A BELT CONVEYOR | US10907981 | 2005-04-22 | US20060237292A1 | 2006-10-26 | Robert Ryan |
| A kit and associated methods for converting a pre-existing conveyor frame into a belt conveyor. The converted conveyor comprises a U-shaped pan mounted to the top of a pre-existing conveyor frame. The U-shaped pan has a pair of side walls flanking a base. A carryway is fastened to the base of the pan to support a modular conveyor belt. Liners extending from the top of the side walls extend into the pan to act as low-friction side rails. Inverted-U-shaped guides attached to the bottom portion of the pre-existing frame at periodically spaced frame supports guide the belt in the returnway beneath the carryway. Spacers interposed between the frame supports and the frame provide vertical and lateral clearance for the belt along the returnway. The kit provides parts for converting a pre-existing conveyor frame into a belt conveyor. | ||||||

| 232 | Conveyor for a clean room | US138285 | 1987-12-24 | US4821866A | 1989-04-18 | Hans L. Melgaard |
| A conveyor for transporting articles to or from a clean room or from one place to another within a clean room. The conveyor has housings extending along either side of the path of conveyor travel. Extending between the housings are conveying members, usually metal rods, elongated perpendicularly to the path of conveyor travel. Each housing is slotted so that the ends of the conveying members may extend therethrough. Within each housing are rollers journaled to the ends of the conveying members and a track. The track receives and guides the rollers. Extending along and in air communication with each housing is a plenum, and between each housing and its plenum is an air restriction sheet that restricts the flow of air. The conveyor also includes a blower for drawing a partial vacuum within each plenum thus drawing a lesser vacuum in the housing. Each housing, plenum, air restriction sheet, and blower are arranged so that a pressure differential is created between the housing and plenum. The pressure differential must be great enough to cause air to flow upwardly through the slot of each housing from the area surrounding the surface of the conveying members. The air flow should flow through the slots of the housing at an average velocity of not less than about one hundred feet per minute. The movement of air through the slots draws with it contaminants on or near the surfaces of the conveying members. | ||||||
| 233 | Apparatus for actuating a breakaway conveyor section | US908710 | 1986-09-18 | US4753337A | 1988-06-28 | Robert M. Grosjean |
| An apparatus for actuating a breakaway conveyor section includes an actuating means positioned below a lower edge of a fire door adapted to move vertically downward along an outside wall of a building to close an opening. A breakaway conveyor section is pivotly connected to an end of a fixed conveyor section outside the building and extends adjacent to an end of a fixed conveyor section inside the building and extending into the opening in the wall. The actuating means includes an actuating plate positioned below a lower edge of the fire door and pivotally connected to a pair of generally vertically extending slides by a pair of lever arms. The slides are maintained in an upper position by a pair of link arms pivotally connected to form an over center mechanism attached between the slides and the conveyor inside the building. A lower end of the slides is slidingly attached to horizontal slides which extend through the opening in the wall to support a free end of the breakaway conveyor section. When the fire door is released, it falls, striking the actuating plate which pivots about the vertical slides to release the over center mechanism and allows the vertical slides to drop. The falling vertical slides actuate the horizontal slides to retract them through the wall and allow the breakaway conveyor section free end to pivot downwardly out of the way of the falling fire door. | ||||||
| 234 | Pressurized explosion containing conveyor | US415250 | 1982-09-07 | US4491215A | 1985-01-01 | Hans J. Meyer |
| A conveyor, e.g. for coal has a conveyor box and a cylindrical housing surrounding this conveyor box. The cavities between conveyor box and housing are sealed by bulkhead(s) in which burst plate(s) are present which seal the cavities dust-tightly, but are destroyed in the case of an explosion so that rapid pressure equalization can occur between the conveyor compartment and the cavities. Preferably there is an aperture with a dust-proof but not pressure tight seal between the cavities and the conveyor box, allowing pressure equalization in normal operation.Advantageously the condition of the burst plate is monitored by suitable means. | ||||||

| A part of the arcuate guides for the hinged belt (13) of the conveyor consists of solid curved pieces (247, 270) which are fastened releasably to parts of the conveyor frame. In the region of the drive station, guide plates (35; 299) which are fastened to the side pieces (17, 18; 220) are assigned to the empty side of the hinged belt. A U-shaped baseplate (20; 232) is connected with its upwardly projecting legs, to the side pieces (17, 18; 220). If the conveyor is a lifting conveyor with a lower and an upper horizontal longitudinal section as well as with a longitudinal section which is directed obliquely upwards, the arcuate guides consist of curved crosspieces (33, 34; 276, 294) which extend between the side pieces (17, 18; 220), in the region of the mutually angled longitudinal sections. The lower and middle longitudinal sections of the conveyor can each be connected partly by means of a welded-in gusset plate, the inner sides, lying opposite one another, of the gusset plates (265) and of adjacent side pieces (220) being welded to the curved crosspiece (276). The baseplate (20; 232) leaves an intervention opening (47) free in the region of the drive station (M). Reversing drums (37; 240) for the hinged belt (13) are located at the reversing station (U). A spring element (66) which smooths out changing tensile stresses is adjustable together with the drive unit when the hinged belt (13) is tensioned. The abovementioned features permit a compact construction, resistant to warping and to bending, of the conveyor, together with a long life. The invention also relates to a process for manufacturing the conveyor. | ||||||

| 237 | Endless belt conveyor system | US847325 | 1977-10-31 | US4128166A | 1978-12-05 | Lawrence H. G. Kovats |
| An endless belt conveyor for heavy materials handling is provided in which shock forces generated by the loading of heavy objects onto the conveyor are absorbed in the vertical, longitudinal and lateral directions with respect to the conveyor by resilient suspension means such as a plurality of rubber shear spring blocks which are associated with the support structure for the track upon which the conveyor belt moves. The belt is comprised of slat links having a central transverse reinforcing beam and slat link covers surrounding the transverse reinforcing beam which converge to either side of the beam at a point intermediate the vertical distance between the top and bottom portions of the beam. Material loaded on top of the conveyor slat links contacts the higher portion of the slat link at the portion of the slat link where the beam is located, the beam acting to distribute the shock from the material loaded thereon along its length and to transmit such shock loadings to the conveyor support structure which absorbs the shock. | ||||||
