Abstract
A swivel caster method and apparatus including wheels rotatably coupled to a housing, wherein the wheels include a toothed cog on inner sides thereof. The housing is pivotally mounted to an article by a mounting stem having a keyed aperture. A brake lever bracket is pivotally coupled to the housing and includes a brake pin engageable with the toothed cog to prevent wheel movement relative to the housing. A swivel lever bracket is also pivotally coupled to the housing and includes a keyed shaft engageable with the keyed aperture of the mounting stem to prevent mounting stem movement relative to the housing. The brake pin of the brake lever bracket is engageable with the swivel lever bracket to pivot the swivel lever bracket to engage the keyed shaft with the keyed aperture when the brake pin is engaged with the toothed cog. A biasing member mounted to the housing is engageable with first and second sides of a cam member on the brake lever bracket to disengage the brake pin from the toothed cog and disengage the keyed shaft from the keyed aperture, and alternatively to engage the brake pin with the toothed cog and to engage the keyed shaft with the keyed aperture.
