  • Patent number: 3940172
    Abstract: A pencil-size instrument body has a manually operable valve to control an air passage connected to a vacuum source. A first hollow axle projecting forward from the body carries a rotary finger control member. A rigid air tube of small diameter is mounted by one end in a second hollow axle and constitutes therewith a replaceable probe assembly that plugs into the first hollow axle. A rotary hub member on the second hollow axle is operated by the rotary finger control member and is connected to the end of a coil spring that rotatably embraces the rigid air tube. The second end of the coil spring is connected to a rotary tip member on the rigid air tube that picks up small objects by vacuum action and rotates the objects under control of the finger control member.
