| A portable, handheld envelope opening device is disclosed. The envelope opening device has a head portion and a handle portion. The head portion includes a slot defined by a pair of opposing walls and a base plate. The walls being spaced so as to guide the passage of an envelope and preferably are slightly angled to provide a tapered insertion end. A pair of rotary discs disposed within the head portion adjacent the base plate intersects in partially overlapping fashion along a centerline of said slot. The discs are spaced and positioned adjacent the base plate. The first disc includes a cutting edge, and the second disc is adapted to urge the envelope into engagement with the first cutting disc to sever a marginal edge of the envelope to expose the contents. A motor is coupled through a gearbox to the rotary discs to drive the discs. A switch is used to couple the motor to a battery power supply. In one embodiment, a decorative edge is applied to the envelope but the cutting disc by providing a sawtooth or undulating cutting edge on the disc. | ||||||
| 163 | Dehider regulator valve | US15826906 | 2017-11-30 | US10034480B2 | 2018-07-31 | Timothy Grinaski |
