Abstract: The hammers provide multiple impact points for debris, by providing impact points via tips at different radii from the axis of rotation of the hammer mill. The tips preferably are at substantially the same radius from the axis of rotation of the hammer about the hammer support shaft, so that efficiency is maintained even as the hammers lay back. The multiple impact points produce a more effective result, by partially sizing the debris on initial impact, before more precise final sizing in the grinding chamber. Angled surfaces on the hammer tips provide more effective shearing and tearing action than with conventional bar hammers. Wear patterns are such that grinding efficiency as the hammers wear down is maintained throughout the life of the replaceable tips. Preferably, the hammers weigh substantially more than conventional hammers, to provide a higher energy impact, and to reduce the tendency of the hammers to lay back.

Abstract: A sortation table having apparatus to gradually slow moving articles to a stop and return the articles to a position for further processing.

Abstract: Apparatus and method for facilitating the replacement of an endless conveyor belt having arcuate outer and inner edge portions. During the operation of the endless conveyor belt a plurality of cooperating pairs of guide rollers are in contact with shoulder portions of the endless conveyor belt adjacent to the arcuate outer edge portion to maintain the endless conveyor belt moving in a desired path. One of each cooperating pairs of rollers is mounted for movement between a first location whereat the cooperating pair of rollers are located to contact the shoulder portions and a second location whereat the cooperating pairs of rollers are spaced apart a distance permitting passage of the shoulder portions therebetween.

Abstract: An adjustable guide assembly for mounting on the upper edge of a longitudinal retaining wall defining a cargo container well of a well car adapted for accommodating containers of different widths in the well, has a base member and a rockable guide member. The guide member has a narrow-container stabilizer surface, a narrow-container loading assistance cam surface, and a wide-container loading assistance cam surface, which are selectively operative by swingably positioning the guide member relative to the base member.

Abstract: A high-rate portable self-contained combination screening/dosing/mixing plant is mounted on a single tractor trailer for highway travel in most states without requiring travel escort vehicles. The plant has a nominal capacity of about 100 tons of soil or dirt per hour, and includes an apparatus train for preliminary separation of large objects, hopper storage, uniform feed rate, shredding-pulverization, particle size screening, additive dosing, mixing and conveyance to an elevated position for transfer to a dump truck, bin or pile.

Abstract: Apparatus wherein an endless moving conveyor belt is trained around two spaced apart shafts and wherein at least one of the shafts is mounted in a bearing that is resiliently urged in a direction away from the other shaft to provide the proper tension in the endless moving conveyor belt, and shock absorbing apparatus is provided for absorbing excessive forces placed on the bearing with or without the resilient urging of the bearing.

Abstract: Apparatus for supporting the guide members for guiding the moving endless chain for moving an endless belt conveyor, and in particular an endless conveyor for a power turn, mounted on a support frame wherein the guide members are mounted on a support member and at least one isolation member comprising a resilient sound and vibration deadening material is provided and the support member and support frame are secured together with the at least one isolation member located therebetween so as to isolate the support member from the support frame.

Abstract: A loading dock range finding system is provided for permitting a driver of a vehicle backing towards a loading dock to determine a distance of the back end of the vehicle from a reference point at the loading dock. An ultrasonic transmitting and receiving transducer is positioned adjacent the loading dock for sending signals towards a back end of the truck, which are reflected and received by the transducer. A display unit is connected to the transducer and is mounted at a location adjacent the loading dock so that a visual display on the display unit can be easily viewed by a driver of the vehicle looking through his rear view mirror. A distance between the back end of the vehicle and the reference point is displayed in reversed image fashion on the visual display so that when the driver views the image through his rear view mirror, it is not a reversed image.
