Abstract: A twin wheel caster with a brake assembly formed as an integral part of the caster housing. The housing has a central body defining a notch therein and a resilient braking arm integrally formed with and extending downwardly from the central body movable between an unlocked position, whereby the caster wheels are permitted to rotate, and a locked position, whereby the wheels are prevented from rotating.

Abstract: The invention relates to an ignitor box, or chamber, for use with a gas fired grill wherein a piezoelectric device strikes a spark that ignites the gas from an adjacent burner. This ignitor chamber is of flared form enclosed on three sides with the fourth side open and facing the burner for admission of gas into the chamber directly from the burner. The top and bottom walls of the chamber are also enclosed, but the top wall is provided with a raised cupola open at opposite ends for the circulation of air:(1) to effect the admission of oxygen for mixture with the incoming gas from the burner to provide a more combustible mixture for ready ignition when the spark is struck;(2) also to allow dissipation of combustion gases trapped in the ignitor chamber immediately after combustion.
