A coil eptimg 46 eneircles the shaft 43 Within sleeve 44, one end of seid spring being eonneeted to the Shaft end the Aothel' end to the base 10, An operating); oord 47 ene'ees .eeeve 114 and. is pirovdet' with a hande 48. From the foegong it obvieus that e puit on the cord 47 will rethe a'ltemediete gearing imtaneousy rotate the wenn ehetts, e, eyese mutation tete shaft 43 in one direction, and through emite tion of said sbatte.
