    摘要： THIS INVENTION IS FOR A DISPENSING DEVICE HAVING A FREELY RESTING SHALLOW HEAD SUPPORTED ON CLIPS SPACED AT 120* INTERVALS AROUND THE PERIPHERY OF A SUPPORTING DISK TO WHICH THE CLIPS ARE ATTACHED. THE HEAD IS REMOVED SIMPLY BY APPLYING LIGHT PRESSURE TO ITS PERIPHERY SO THAT IT PIVOTS ON TWEO OF THE THREE SUPPORTING CLIPS AFTER WHICH IT CAN BE SIMPLY LIFTED OUT OF THE DEVICE THEREBY PERMITTING ACCESS TO THE INTERIOR WHERE THE ADJUSTING MECHANISM IS LOCATED. ADJUSTING OF THE DISPENSING RATE TAKES PLACE SIMPLY BY LOOSENING A WINGNUT AND ROTATING THE UPPER SPRING SUPPORTING DISK IN A CLOCKWISE DIRECTION TO RAISE THE DISK AND THE DISPENSING RATE ON A THREADED STUD OR IN A COUNTERCLOCKWISE DIRECTION TO LOWER THE DISPENSING RATE. THE DISPENSER OF THIS INVENTION ALSO FEATURES A SIMPLIFIED CENTRALIZING AND LOCKING MECHANISM.

    摘要： A DOCKBOARD ASSEMBLY INCLUDING A SUPPORT MEANS WITH A RAMP PIVOTALLY CONNECTED TO THE SUPPORT MEANS AND A LIP PIVOTALLY CONNECTED TO THE RAMP FOR MOVEMENT BE TWEEN A PENDENT POSITION AND AN EXTENDED POSITION TO FORM AN EXTENSION OF THE RAMP. A CHAIN IS CONNECTED AT ONE END TO THE LIP AND IS CONNECTED AT THE OTHER END TO A MANUALLY GRASPABLE HANDLE, BOTH OF WHICH ARE CONNECTED TO A CABLE WHICH RETRACTS THE CHAIN AND HANDLE TO A NONUSE POSITION. THE CABLE IS EITHER ATTACHED TO A RETRIEVER REEL OR A WEIGHT.
