[Also in Division A4] An electrical floor polisher comprises a forked handle 7 having a stub 8 at each end of the fork which is rotatably mounted in a bearing 9, 10 having an opening of greater diameter than that of the stub and having a bush 12 inserted into the bearing from the side opposite that from which the stub is inserted. Part 15 is attached to the bearing, e.g. by screws to hold the bush in position, and a seal 17, 18 and 19 seals the hood 4 where the handle enters therein. In Fig. 2, the handle may be inserted without deformation of the forks by suitable inclinations. In the embodiment of Figs. 5-7 (not shown), the bearing is shaped so that the handle may be inserted without inclination or deformation of the fork. The cable 16 may be passed down one or both sides of the fork; through the bush or bushes into the housing 3. |
