Interesting Patent of the month
Title of the Invention: Electrified table cloth
Publication number: US5107620
Publication type: Granted Patent
Application number: US 07/518,429
Filing date: May 03, 1990
Inventors: Richard E. Mahan
Abstract:
An electrified table cloth for preventing crawling insects from gaining access to the consumer’s food or drink comprises a cloth formed of electrically insulated material which has at least one pair of parallel electrically conductive strips secured to the edge or border of the cloth to completely encircle the cloth and which are connected to a low voltage DC battery also secured to the cloth. The strips of electrical conductive material are spaced apart sufficiently to normally prevent completion of a circuit across the strips and for completion of a circuit across said strips through an insert’s body as the insect attempts to traverse the strips when crawling acorss the edge of the cloth. The current passing through the insect’s body is sufficient to produce a sensation which will discourage further travel across the edge of the cloth. A consumer who may come into contact with the strips will usually not feel the current and, even if the consumer is wet, the current will produce only a slight tingling sensation. The electrical apparatus may also be provided in kit form to be installed on table cloths by the consumer.
