Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 93 words
An anti-pollution apparatus for smoke stacks, comprising, a vertical smoke stack, a plurality of motor and fan blades carried within said stack providing a means of pulling air up through said stack, a charcoal filter carried within said stack providing purifying means for the gases being pulled through said stack, support means for said filter carried within said stack, a plurality of electrodes carried by said stack for producing an intermittent electric arc, high voltage transformer means carried by said apparatus with distributor and motor means for alternating the arcing within said stack.
Claim 2
Dependent Claim 93 words
An anti-pollution apparatus for smoke stacks, comprising, a vertical smoke stack, a plurality of motor and fan blades carried within said stack providing a means of pulling air up through said stack, a charcoal filter carried within said stack providing purifying means for the gases being pulled through said stack, support means for said filter carried within said stack, a plurality of electrodes carried by said stack for producing an intermittent electric arc, high voltage transformer means carried by said apparatus with distributor and motor means for alternating the arcing within said stack.
Claim 3
Dependent Claim 100 words
The combination according to claim 1, wherein said stack is provided with an inlet opening at its lower extremity for smoke to be pulled into said stack and said electrodes produce a high voltage arc which is intermittent between the oppositely opposed electrodes by means of a rotating distributor, said distributor supplying voltage from a power source for the input of said high voltage transformer, the output of said transformers carrying the high tension voltage to said electodes on the interior of said stack and simultaneously as said electrodes are arcing, said fan blades are pulling air through said filter.
Claim 4
Dependent Claim 102 words
The combination according to claim 2, wherein said fan blades are secured to electric motors that are fixedly secured and spaced apart on the interior of said stack and a partial vacuum is created in order to pull said air through said charcoal filter, said charcoal filter serving to remove the noxious gases and smoke particles from said air being drawn through said stack and said high voltage electrodes serve to further break up said smoke particles and to purify said air, said charcoal filter being the final purifying element which will cause substantially clean air to be egressed from said stack.
Claim 5
Dependent Claim 61 words
The combination according to claim 3, wherein repair of said motors and said fan blades within said stack is accomplished by a worker ascending stairs secured to the wall of said stack, said workman having access to said motors by means of a hinged door secured to said stack, said hinged door covering an opening through said wall of said stack.
