Power driven bottle cap remover

Claim 1

A power driven device for twisting a crown cap loose from a circular head of a neck of a bottle on which said cap is crimped and then separating said cap from said head, said device including: a. a rotational power generating assembly that includes support means, an electric motor mounted on said support means, a driven shaft; a bearing mounted on said support means that rotatably and slidably supports said driven shaft; a plurality of speed reducing gears rotatably supported from said support means and driven by said motor, with a first of said gears being elongate and rotating on an axis parallel to said shaft; electric circuit means for supplying electric power to said motor; and a normally open electric switch that forms a part of said electric circuit, said switch including a spring loaded member that when moved from a first position to a second position closes said electric circuit to energize said electric motor for the latter to drive said plurality of gears; b. a second gear secured to said driven shaft that engages said first gear and may move longitudinally relative thereto, said second gear when said driven shaft moved longitudinally from a first to a second position causing said second gear to pressure contact said spring loaded member and move the same to said second position; c. an inverted cup shaped head that includes a top and a cylindrical sidewall that extends outwardly therefrom, said top secured to an end of said driven shaft opposite from the end thereof that supports said second gear, said head including a tubular centered boss that extends outwardly from said top within said boss having a closed end adjacent said top, and said head having an open end through which said cap and neck may be moved towards said top; d. first spring means that at all times tends to maintain said head in a first position in which said second gear and said switch actuating members are in said first positions; e. a rod slidably mounted in said boss and extending outwardly therefrom; f. second spring means that at all times tend to maintain said rod in a first position in which it is spaced from said closed end of said boss, but said rod capable of being moved to a second position to pressure contact said closed end to move said head in a direction to dispose said second gear and actuating member to said second positions; and g. cap engaging means that grip said cap when the latter is moved towards said top to a degree that it pressure contacts said rod to move said rod to said second position, with said head and cap engaging means being rotated to twist said cap from said head, and said rod as said bottle is thereafter moved away from said head moving from said second to said first position to force said cap that has been removed outwardly from said cap engaging means.
