Title: Motor drive hand brush and grinding machine - has two drives coaxially installed and rotating in opposite directions
Inventor: SCHMIDT MARTIN
IPC: A46B13/02
Filed: 1973-10-31
Abstract: Hand brush and grinding machines with drives working forward are known to required manual power intervention. This disadvantage is removed in a simple manner by the invention.
