  • Patent number: 5209248
    Abstract: A small, portable, battery operated smoking pipe filling and cleaning tool. A series of small stepped plastic tubes are prefilled with tamped tobacco by the user and placed in a row in the case. To load a pipe, a tobacco filled tube is picked up and inserted within a pipe loader having a fixed central tamper surrounded by an annular spring loaded tube holder. The pipe bowl is then inverted over the tube and pressed downward. The tube, driven by the pipe bowl down against the holder, descends. The fixed tamper shoves the tobacco from the tube into the bowl. When the pipe is removed from the device the tube will readily fall free and the pipe is loaded with a charge of tobacco, correctly tamped for the smoker. The entire operation can be done by feel in one single up and down reciprocating motion. A battery operated, motor driven reamer is centrally mounted within an ash receptacle. A switch causes the reamer to rotate and vibrate. The pipe bowl is inverted over the brush and pressed downward.
