Abstract: A conveyor belt cleaner scraper blade for cleaning the surface of a conveyor belt. The scraper blade includes a base member adapted to be attached to a cross shaft of a conveyor belt cleaner and a wear section which extends outwardly from the base member to a scraping tip. The wear section includes a plurality of temperature sensors located along the length of the wear section, a plurality of wear sensors located along the length of the wear section, and one or more strain gage sensors located along the length of the wear section. Each of the sensors is in electrical communication with an electrical transmitter member that is adapted to provide an electrical output signal to a computer. The temperature sensors provide an indication of the temperature of the wear section at the location of each temperature sensor. The wear rate sensors provide an indication of the location of the scraping tip with respect to the base member as the wear section wears away and the tip moves closer to the base member.

Abstract: A conveyor belt cleaner and tensioner assembly adapted to be attached to a cross shaft. The conveyor belt cleaner and tensioner assembly includes a mounting base adapted to be mounted to the cross shaft and an arm member having a first end and a second end. The first end of the arm member is pivotally attached to the mounting base for pivotal movement about a pivot axis. A scraper blade is attached to the second end of the arm member. A gas spring tensioner has a first end pivotally attached to the mounting base and a second end pivotally attached the arm member. The tensioner includes a housing and a ram having a first end located within the housing and a second end located externally of the housing. The ram is extendable and retractable with respect to the housing to thereby pivot the arm member and the scraper blade about the pivot axis. The scraper blade includes a metal scraping tip having an elastomeric wear-in tip.

A base member is adapted to be attached to the scraping member. The base member includes one or more bores adapted to be aligned with a respective aperture in each mounting member. The bore includes inwardly projecting first and second annular ribs. A mounting pin having a shank is adapted to be inserted into the apertures of the first and second mounting members and into the bore of the base member to thereby connect the base member to the mounting members. The shank of the pin includes a first annular groove adapted to receive and interlock with the first rib of the base member and a second annular groove adapted to receive and interlock with the second annular rib of the base member.

Abstract: A vibrator mounting arrangement for attaching a vibrator to an object having one of a plurality of different mounting surface configurations. The mounting arrangement includes a mounting base adapted to receive the vibrator. The mounting base includes first and second downwardly extending curved lips. A first leg having a first foot member and a first curved flange is attached to the first lip. The first flange includes a plurality of slots which allow the first leg to be pivotally rotated to position the first foot member at various different angles as desired. A second leg is attached to the second lip of the mounting base. The second leg includes a second foot member and a curved flange which includes a plurality of slots. The slots of the second flange permit the second foot member to be pivotally rotated to position the second foot member at various different angles as desired.

Abstract: A hinged access door arrangement is provided which includes a flange member adapted to be secured to a housing which defines an aperture therethrough to provide access to the housing. A cover member is adapted to overly the aperture when in a closed position. A plurality of first hinge members are attached to the cover member at a plurality of locations around the cover member. Each first hinge member is adapted to form part of a hinge mechanism to provide selective pivotal movement of the cover member about a respective axis. A plurality of second hinge members are attached to the flange member at a plurality of locations around the flange member. Each second hinge member is positioned to cooperate with a first hinge member to form part of a hinge mechanism. A first hinge pin pivotally connects a selected first one of the first hinge members to a second hinge member to form a first hinge mechanism having a first pivot axis about which the cover member is selectively pivotal.

Abstract: An impact pillow for resiliently supporting a conveyor belt in an impact zone in a conveyor transfer point. The impact pillow includes a base wall, first and second side walls each extending upwardly from said base wall to a top edge, and first and second end walls each extending upwardly from said base to a top edge and between said side walls. A top wall extends from and between the top edges of the side walls and the end walls forming a support surface over which the conveyor belt slides. The top wall, base wall, end walls and side walls combine to form an integral shell having a closed cushioning chamber adapted to receive and contain a cushioning substance. The cushioning substance may be a gas, a fluid or a resilient solid material. The impact pillow resiliently supports the moving conveyor belt as material is loaded onto the conveyor belt at the transfer point and absorbs the impact forces generated on the conveyor belt during the loading process.

Abstract: A tensioning device for imparting torsional bias to a shaft. The tensioning device includes a coupling member of resilient material having a first end and a second end. The first end of the coupling member is connected to the shaft for rotation therewith. A driven member is connected to the second end of the coupling member such that the driven member is relatively rotatable with respect to the shaft. A drive member is associated with the driven member for selectively rotating the driven member to any of a number of infinitely variable positions. The tensioning device is effective to rotate the shaft to a desired position and to store torsional force in the coupling member when the second end of the coupling member is rotated with respect to the first end of the coupling member. The tensioning device includes a torsion indicating member for indicating the amount of torsional force being applied to the shaft by the coupling member.

Abstract: A tensioning device is provided for selecting and imparting torsional bias to a shaft and simultaneously providing a shock absorbing mechanism. The device includes a resilient elastomeric biasing member in the form of a web extending radially between the shaft and an actuator member. The first end of the biasing member is connected to the shaft for conjoint rotation therewith and the second end of the biasing member is connected to the actuator member. A locking mechanism selectively connects the actuator member to a fixed frame after a torsional biasing force is imparted to the shaft.

Abstract: A tensioning device is provided for selecting and imparting torsional bias to a shaft and simultaneously providing a shock absorbing mechanism, the device including a first hub member selectively connectable to the shaft, a second hub member rotatable wiht respect to the first hub member, a torsion coupling of elastomeric material connected at a first end to the first hub and at the other end to the second hub, and a locking mechanism to lock the second hub to a stationary frame member when the desired torque has been reached.

Abstract: A conveyor belt support mechanism comprising a plurality of slider bars, each having multiple low friction wear surfaces with one wear surface in sliding engagement with the conveyor belt and an adjustment mechanism to compensate for wear to said wear surface by moving the slide bar closer to the conveyor belt as the wear surface wears, and a vertical support system for positioning said slider bars. When loads such as impact loads are placed on the conveyor belt, the slider bars support the conveyor belt and prevent the belt from sagging and stretching. As one wear surface of a slider bar becomes worn past an acceptable limit, the slider bar may be removed and repositioned so that a new wear surface engages the conveyor belt.
