Description: |
| This motor controller provides on-off functions for an air compressor. According to later court testimony, the inventor said that he later created a three-point switch was designed so that "if a hose blew off, creating an abnormal low pressure, the pump would stop. All these devices were used, chiefly, on beer pumps. He states that about twenty-five of these devices were made and sold... He did not seek for not obtain any patent on this three point modification of his original control." |
