Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
214 words
An apparatus for destroying flying insects, comprising: a. a casing having an intake opening and an outlet opening at opposite ends thereof; b. a motor housed in said casing and having a shaft which extends between the two openings of the casing; c. a first rack of teeth mounted on the rotatable shaft of the motor; d. a second rack of teeth stationarily mounted across an opening of the casing and positioned such that the teeth of the first rack, when rotated, pass between the teeth of the second rack to effect a cooperative chopping action which destroys flying insects drawn between the racks; and e. a fan blade wheel mounted on the rotatable shaft of the motor for producing a current of air between the openings of the casing such that flying insects are drawn through said intake opening into the range of action of the racks, f. said first and second racks being located in said housing adjacent said intake opening of the casing, and g. said motor and fan blade wheel being mounted underneath said first and second racks with said fan blade wheel being located in the vicinity of said outlet opening and said motor being downstream of said first and second racks and upstream of said fan blade wheel.
