Abstract
The invention provides a braking system for a powered oscillating hand tool which tool comprises (i) a housing; (ii) a drive unit (2) having an electric motor (4) and a drive shaft (8); (iii) a bearing (28) mounted on the drive shaft (8) and located radially eccentrically relative to the drive shaft (8), adapted to drive a second drive shaft (26); (iv) means (22) for mounting an oscillating head (24) on the second drive shaft (26) and (v) brake means (30) for providing braking between the oscillating head (24) and the housing (6). The brake means (30) comprises (i) a reaction surface (35, 46); (ii) a resilient support member (32, 40) formed from a resilient material which material, under compression, provides a resultant load on the contact surface and (iii) an abrasion resistant contact layer (34, 44) mounted on the support member (32, 40).
