Abstract
In a twin head dry shaver, the shaver heads are carried at the upper end of a four-bar mounting linkage comprising vertical side members 1A, 1B and bell crank links 2, 3 pivotally connected to the side members at points 7, 8 and 9, 11. The links are pivotally connected to the frame by pivot pins 4 and 6 set above and mid-way between the connections to the side members, thus rendering the heads highly sensitive to cut of balance forces acting on the heads so that they may move vertically, relative to each other to restore the balance.
