Automatic dispenser for paper towels severable from a continuous roll
First Claim
1. An apparatus for dispensing paper towels severable from a continuous roll comprising:
- a housing having a back plate, and a cover having a lower portion thereof being hingedly connected to a bottom portion of said housing, said cover including a dispensing port on the lower portion thereof;
a support for a paper roll;
a dragging roller and an opposing pressure roller for dragging a paper strip unrolled from said paper roll;
a motor for operating said dragging roller;
a cutting blade mounted in the dispensing port for severing a paper towel from the paper roll;
transmission means provided between said motor and said dragging roller, mounted on a side shoulder integral with said housing,an ON-OFF circuit for supplying power to the motor for an adjustable, predetermined time period;
a photocell for actuating said ON-OFF circuit;
an electronic switch for supplying power to said ON-OFF circuit through a first enable circuit; and

Abstract
An automatic dispenser for paper towels shaped in strips of an appropriate length severable from a continuous feed roll, outputs a portion of paper of an appropriate length cutting it with a stationary blade. The blade is located in a less accessible area of the apparatus for user safety reasons. Dispensing is usually controlled by a photoelectric cell or proximity detector, which actuates an ON-OFF switch for supplying power to a motor during a time period predetermined by a timer, thereby causing rotation of a dragging roller adapted to cause a certain extent of unrolling of the feed roll. In case of saturation of the photoelectric cell caused by improperly keeping it intercepted, an electronic switch disables the photo cell and enables an emergency push-button while also lighting a signal lamp to advise of a change in the operating condition, which requires a push of an emergency button.
