Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
189 words
An apparatus for suppressing ink mist in a printing press, comprising: a. an electrically conductive inking roller having an outwardly extending spindle at an end portion thereof, said spindle having a socket formed extending inwardly adjacent a side wall and an end wall formed therein; b. an electrically insulating bushing mounted adjacent said side wall in said socket in said spindle; c. an electrically insulating journal mounted externally of said spindle, said electrically insulating journal having an opening formed therein adjacent said socket in said spindle, said insulating journal further having a rim adjacent said opening for retaining said electrically insulating bushing in said socket in said spindle; d. means for supplying electrical energy to electrify said inking roller, wherein the electrified inking roller attracts and suppresses the ink mist; and e. an electrically insulating cap mounted with the printing press, said electrically insulating cap insulating said means for supplying electrical energy from the printing press, said electrically insulating cap having a portion extending inwardly through said opening in said electrically insulating journal, said inwardly extending portion having an external surface adjacent said electrically insulating bushing in said spindle.
Claim 2
Independent Claim
189 words
An apparatus for suppressing ink mist in a printing press, comprising: a. an electrically conductive inking roller having an outwardly extending spindle at an end portion thereof, said spindle having a socket formed extending inwardly adjacent a side wall and an end wall formed therein; b. an electrically insulating bushing mounted adjacent said side wall in said socket in said spindle; c. an electrically insulating journal mounted externally of said spindle, said electrically insulating journal having an opening formed therein adjacent said socket in said spindle, said insulating journal further having a rim adjacent said opening for retaining said electrically insulating bushing in said socket in said spindle; d. means for supplying electrical energy to electrify said inking roller, wherein the electrified inking roller attracts and suppresses the ink mist; and e. an electrically insulating cap mounted with the printing press, said electrically insulating cap insulating said means for supplying electrical energy from the printing press, said electrically insulating cap having a portion extending inwardly through said opening in said electrically insulating journal, said inwardly extending portion having an external surface adjacent said electrically insulating bushing in said spindle.
Claim 3
Dependent Claim
33 words
The structure of claim 1, further including: an electrically conductive plug mounted in said end wall in said socket in said spindle to receive electrical energy from said means for supplying electrical energy.
Claim 4
Dependent Claim
71 words
The structure of claim 2, wherein said means for supplying electrical energy comprises: a. an electrical power supply; b. an electrical conductor connected with said electrical power supply; c. a contact mounted in said inwardly extending portion of said electrically insulating Cap, said contact being in electrical connection with said electrical conductor; and d. a plunger mounted in said contact and electrically connecting said electrical conductor with said electrically conductive plug.
Claim 5
Dependent Claim
68 words
The structure of claim 3, wherein the printing press is equipped with a plurality of inking rollers and wherein said electrical power supply comprises: a. an alternating current voltage source; and b. a plurality of transformers, each individually connected to one of said plurality of rollers, wherein a malfunction of one of said plurality of transformers does not prevent electrifying of the remainder of said plurality of rollers.
Claim 6
Dependent Claim
56 words
The structure of claim 1, wherein: a. said electrically conductive inking roller further comprises a metal body having a vulcanized rubber coating along a portion of an outer surface thereof and uncovered end portions of said outer surface; and b. sleeve means for electrically insulating said end portions of said inking roller from the printing press.
