APPARATUS FOR SUPPORTING ARTICLES IN A DISHWASHER
First Claim
1. Apparatus for supporting articles in a dishwasher, comprising:
- an open basket having opposite lateral sides;
a pair of wheels on each said side with each pair of wheels vertically spaced to engage opposite sides of a supporting guide track that forms a part of said dishwasher;
a pair of levers each movable about a fulcrum at a said lateral side and each lever rotatably carrying a wheel spaced from the corresponding fulcrum;
linkage means of fixed length interconnecting said levers at areas spaced from said fulcrum for maintaining said vertical spacing of the wheels on moving said levers about their said fulcrums to adjust the position of said pair of wheels relative to their said basket side; and
means for releasably retaining one of said levers in a selected one of a plurality of positions.

Abstract
A wheeled basket for supporting articles in a dishwasher so that the basket rolls on a horizontal track and can be pulled out for loading and unloading and can be pushed into the dishwasher for the washing operation in which a pair of wheels is located on each side of the basket and with each pair of wheels being vertically spaced to engage opposite sides of a supporting guide track that forms a part of the dishwasher, a pair of levers each movable about a fulcrum on the basket at a lateral side with each lever rotatably carrying a wheel spaced from the corresponding fulcrum, a linkage of fixed length interconnecting the levers at areas spaced from the fulcrums and with the levers being movable in vertical planes about their fulcrums for changing the vertical elevation of the wheels while still maintaining the vertical spacing between each pair of wheels. The invention also includes multiple spaced retainers on each side of the basket for holding the levers in adjusted position so that the vertical spacing of the pair of wheels on each side of the basket will be maintained until the levers are changed to a new setting. This varying of the vertical positions of the pair of wheels regulates the elevation of the basket in the dishwasher and permits the basket to accommodate articles of various height.
