Abstract
Unitary system for changing catalyst particles in a catalytic converter mounted in a vehicle exhaust system. The system attaches to and hangs from the converter, applied rotary off-center vibration, and collects the liberated particles in a self-supporting canister. Vacuum means, acting through the exhaust pipe, aids in starting the emptying process and acts to refill the converter.
Claims23
In a system for exchanging catalytic particles in a horizontally disposed catalytic exhaust converter having external longitudinal flanges containing a catalyst bed and a bottom fill hole therein, said system having at least one canister assembly constructed and arranged to selectively receive or supply said catalytic particles, vacuum means for creating negative pressure within said converter, means supported from said converter arranged to engage said canister assembly in connection with said fill hole, and means for shaking said converter,
- the improvement wherein said shaking means is fixedly carried by a removable gripping means arranged to selectively engage said converter at spaced-apart points along a transverse line which is longitudinally spaced from said fill hole, said gripping means comprising a transverse first supporting member spacedly suspended from said converter, a second supporting member affixed to and extending upwardly from said first supporting member, and a second gripping member pivotally attached to and extending upwardly from said second supporting member, said gripping members having their upward ends shaped for engagement with said flanges.
In a system for exchanging catalytic particles in a horizontally disposed longitudinal-flange sloped-bed catalytic exhaust converter having a catalyst bed fill hole in the bottom surface thereof, said system comprising:
- a. a canister assembly arranged to selectively receive and supply said catalyst;
- b. vacuum means arranged for creating negative pressure within said converter;
- c. support means for engaging said canister assembly in mating connection with said fill hole;
- and
- d. means for shaking said exhaust converter, the improvement wherein said support means for engaging said canister assembly in mating connection with said fill hole comprises a transverse supporting member spacedly suspended from said converter carrying said means for shaking said converter and a support arm double pivotally attached thereto providing both vertical and horizontal arcuate movement of said support arm.
