Abstract: A compact clamp system for use with conveyor belt rubber skirtboards utilizes a minimum number of parts and is easy to adjust, even if positioned in areas that are difficult to access. A base member is attached to the steel support plate of a conventional conveyor. A stationary support member having a downwardly extending leg is fixedly attached to the base member, and a depending pressure bar assembly is hingedly attached to the support member. A wedge pin assembly including one or more wedge pins is fixedly attached to the downwardly extending leg of the support member to apply an inward force to the pressure bar assembly to thereby urge it against the conveyor belt skirtboard and to release that force to facilitate repositioning of the rubber skirtboard to accommodate wear, for example.

Abstract: A clamp system for use on a belt conveyer for securing and supporting rubber skirtboards from the skirt plates of the conveyor. The clamp system includes first and second stationary supports secured to the skirt plates, a press bar hinged to the lower end of each stationary support, and pressure adjustment means for applying force against the press bar to bias the press bar against one of the skirtboards. As the lower edge of the skirtboard wears away, the clamp can be loosened to enable the skirtboard to be moved downwardly toward the conveyor belt.

Abstract: A system is described for lining or protecting a working surface of a chute, hopper, trough, etc. or other material-handling equipment with a wear-resistant material. The system includes a framework of parallel elongated rails secured to the working surface and separated by spacer bars which define the spacing between adjacent rails. The framework is tack-welded to the working surface. A plurality of wear-resistant panels having opposing side edges are held in place on the rails. The side edges of the panels have recesses for frictionally engaging the rails, and worn panels can be easily removed and replaced when necessary.

Abstract: A mounting system for removably attaching elongated screen rails to upright side panels of a screen deck for screening crushed rock and gravel. A method for suspending a screen rail within the screen deck is disclosed which avoids the need to remove the screen rails when changing screens. In one embodiment, a plurality of anchors are secured to one side of each screen rail, and bolts are used to secure the rails to the side panels. The anchors each include an opening which is larger at the top than at the bottom to allow the head of the bolt to be readily and easily captured by the anchor. The mounting system is much easier to use and much more rapid than previous systems.

Abstract: This invention relates to a replaceable repair device for use to repair the outer terminal edge of a flat spoke of a wing pulley wheel, in general, and more specifically: to a cross-sectionally T-shaped elongated repair device having a top cross-bar, and a lower parallel pair of spaced apart downwardly extending flat legs secured to the cross-bar underside and with the legs adapted for overlapping abutment relation with and secured to the outer surface sides of a flat spoke adjacent the spoke terminal edge, and to the cross-bar of the T-device a metal base plate, having a rubber strip vulcanized thereon, with the metal base plate replaceably tack-welded at interval spots to the cross-bar of the T unit, and by the interval tack-weld spots thereby to avoid welding heat loosening the rubber vulcanization on its metal base plate.

Abstract: A flexible rubber strip or sheet is described which is useful as surfacing material on an idler pulley or the like. The rubber strip includes a row of openings along each end. A pair of spaced-apart metal strips is secured to each end of the rubber strip. A portion of each metal strip is exposed in the openings to enable it to be welded to the surface of a pulley to secure the rubber strip to the pulley to thereby provide a wear surface.

Abstract: A rubber wear layer is molded to a metal sheet, which is relatively thin, in comparison with a side rail for tensioning a vibrating screen, then attached to the side rail, as above a flange which provides a connection with the screen. The rubber layer and sheet may be wider than the width desired for the rail, in which event the wear layer and sheet are trimmed to the desired width, as by shearing. The rubber layer may also have a width less than the sheet, so as to leave a lip along one edge. The aforesaid attachment is made by pins propelled by an explosive charge through the bonded layer, the sheet and the plate at spaced positions. A head of each pin abuts the sheet and the portion which extends past the plate is removed, as by grinding. The sheet may be additionally attached to the rail by spot welds at spaced psitions on the lip, which prevents the heat of welding from adversely affecting the rubber. The lip is placed on the plate opposite the flange which connects with the screen.

Abstract: A replaceable lagging structure, for a conveyor pulley, and specifically to a flexible lagging structure useable and adaptable on different size pulley drums. The structure preferably has a pair of parallel, elongated, arc shaped metal plates which are connected together by a flexible traction rubber pad. The outer elongated arc plate edges are adapted to be spot-welded to the periphery of a pulley drum surface. The arc shape of each metal section is such that the lagging structure is adapted to fit different sized drum pulleys. The thickness of the metal sections does not restrict or hinder the required flexibility of the lagging structure.
