ROLLER ASSEMBLY CALL UP MECHANISM FOR A VEHICLE WASH CONVEYOR
First Claim
1. A roller assembly call up mechanism for a vehicle wash conveyer having an endless chain with a plurality of roller assemblies attached thereto for pushing a vehicle along a slotted track by engaging a tire, the conveyor having a trap door at an entrance end for tire engaging rollers of the roller assemblies to enter the slotted track, the roller assembly call up mechanism being located below the slotted track and comprising:
- a power cylinder;
a crank arm connected to said power cylinder;
an axle connected to said crank arm for rotation therewith and extending parallel to the slotted track in a direction perpendicular to the length thereof;
a ramp connected to said axle for rotation therewith and normally extending generally parallel to the slotted track in a direction lengthwise thereof; and
a link pivotally connected at one end to said ramp and at an opposite end to the trap door whereby when the power cylinder is actuated, the ramp and the trap door are pivoted upwardly.
