  • Patent number: 4240656
    Abstract: Disclosed herein is an apparatus for the picking up and disposal of animal excrements in a hygienic and simple manner. The apparatus provides for one or more lined shovels to be attached to one end of a telescoping shaft. The shaft is provided with a handle, allowing its use as a walking stick. It is optionally provided with a wheel on the end. By placing the shovel end of the shaft on the ground, and depressing the other end of the shaft, the shaft telescopes, causing the shovels to be tilted from their normally upright position to a position in which they are horizontal with the ground and able to pick up the desired excrements. In order to select which of the shovels attached to the shaft is to be tilted to the ground, a pin and wing nut assembly is provided for each shovel. This assembly permits the coupling or decoupling of the individual shovel's tilting lever from the shaft.
