Abstract
A guard basket for protecting people working near an industrial food mixer for preventing them from placing their hands in the way of a mixing tool. The guard basket is made of massive stainless steel bars which are welded together. On each side of the guard basket, the steel bars rise to a level which form handles for providing a way of sliding the basket either into an operating position or removing the basket. A pin is mounted on the mixer adjacent each of the handles. Latches on the handles receive the pins so that the guard basket may swing down to a safety or guard position or up to give access to the bowl. A sensor prevents the mixer from operating when the guard basket is away from the safety or guard position. Another safety circuit requires the bowl and guard to be in a proper position for continuous operation, while allowing the user to jog the bowl into position.
