Patent number: 7600290Abstract: The backpack Multi-Blower provides for the first time an apparatus that is unique in that one person manipulates two separate air discharge tubes in either different or unified positions simultaneously at debris. This multi-blower generates air from separate chambers inside the housing having their own discharge air outlet, thereby creating more combined volume as well as the ability to diversify how the air is directed, they're by blowing with greater ease, control, efficiency and effectiveness. Man-hours reduced significantly in that one person using the multi-blower removes the need for a second man to accompany with separate single port blower. Time saved in that one person coordinates two blower tubes, verses the old way of two people trying to think together in a fluid flow of movement as to effectively moving the debris together. These few listed benefits provide a blower apparatus that has improved drastically its function and use, which will save time, money and man-hours.Type: GrantFiled: April 27, 2004Date of Patent: October 13, 2009Assignee: Twindstorm LLCInventor: Clifford Eli Peters
