ABSTRACT:
A safety guard device for a power tool discharge chute which includes a shaft attached to the chute and extending across the opening of the chute. There are a plurality of elongate spaced-apart blade elements mounted to the shaft for pivoting within the chute and one or more springs or other resilient elements are provided for biasing the blade elements into a closed condition within the chute to prevent operator access through the opening of the chute and permitting the blades to pivot into an open condition so that bulky material may be discharged through the chute.
