Fluid treating structure for electrostatic precipitators

Claim 1

IN AN ELECTROSTATIC PRECIPITATOR INCLUDING A HOUSING HAVING SPACED OPPOSED GAS INLET AND GAS OUTLET OPENINGS AND GAS CLEANING MASS DISPOSED WITHIN SAID HOUSING INTERMEDIATE SAID GAS INLET AND GAS OUTLET OPENINGS AND EXTENDING THEREACROSS, A FLUID TREATING STRUCTURE FOR SAID GAS CLEANING MEANS COMPRISING SPACED PARALLEL UPPER AND LOWER TRACK MEMBERS MOUNTED IN HORIZONTALLY EXTENDING POSITION ADJACENT TO AND ON OPPOSITE SIDES OF SAID GAS INLET OPENING TO EXTEND BEYOND THE EXTREMITIES THEREOF, FLUID HEADER ASSEMBLY MEANS VERTICALLY EXTENDING BETWEEN SAID SPACED HORIZONTALLY MOUNTED TRACK MEMBERS AND INCLUDING FLUID DISTRIBUTING NOZZLES POSITIONED TO DISTRIBUTE FLUID TO SAID GAS CLEANING MEANS, SPACED ROLLERS ROTATABLY MOUNTED ON SAID FLUID HEADER ASSEMBLY MEANS AT THE EXTREMITIES THEREOF TO ENGAGE WITH AND RIDE ON SAID TRACK MEMBERS, ENDLESS BELT MEANS INCLUDING A PAIR OF SPACED SPROCKETS ROTATABLY MOUNTED ADJAENT THE OPPOSITE EXTREMITIES OF ONE OF SAID TRACK MEMBERS AND HAVING AN ENDLESS BELT ENGAGED THEREON TO PROVIDE UPPER AND LOWER HORIZONTAL FLIGHTS CO-EXTENSIVE WITH SAID TRACK MEMBER, POWER MEANS TO DRIVE ONE OF SAID SPROCKETS AND SAID ENDLESS BELT ENGAGED THEREON, A CONNECTING ARM INCLUDING A BODY PORTION EXTENDING LONGITUDINALLY OF SAID ENDLESS BELT BETWEEN AND CONNECTING THE ADJACENT EXTREMITY OF SAID HEADER ASSEMBLY MEANS WITH ONE OF THE FLIGHTS OF SAID ENDLESS BELT, ONE END OF SAID CONNECTING ARM BEING PIVOTALLY MOUNTED TO SAID FLUID HEADER ASSEMBLY MEANS WITH SAID BODY PORTION OF SAID ARM EXTENDING NORMAL TO THE PIVOTAL AXIS AND ALONG SAID ENDLESS BELT, THE OTHER END OF SAID ARM BEING FIXED TO A PORTION OF A FLIGHT OF SAID ENDLESS BELT, SAID BODY PORTION OF SAID CONNECTING ARM BEING OF A PRESELECTED LENGTH TO INSURE FLUID TREATMENT ALONG THE OVER-ALL BREADTH OF SAID GAS CLEANING MEANS AND YET SUFFICIENT TO ALLOW SAID END FASTENED TO SAID ENDLESS BELT TO CHANGE FROM ONE FLIGHT THEREOF TO THE OTHER, AND STOP MEANS MOUNTED ON SAID HEADER ASSEMBLY IN SPACED RELATION FROM THE PIVOTALLY MOUNTED END OF SAID CONNECTING ARM WHEREBY SAID BODY PORTION OF SAID CONNECTING ARM ENGAGES AGAINST SAID STOP MEANS AT THE MOMENT SAID PORTION OF SAID ENDLESS BELT MEANS TO WHICH SAID CONNECTING ARM IS FASTENED ENTERS ONE FLIGHT OF THE BELT FROM THE OTHER.
