Abstract

1422701 Domestic blender RONSON CORP 11 Jan 1973 [11 Jan 1972] 1626/73 Heading B1C In a domestic blender, housing 10, Fig. 2, encloses a motor having a drive shaft 11. Jar base member 20, Figs. 1 and 2, separably mountable on the housing, rotatably supports a driven shaft 37 coupled to food comminuting blades 39 and has means, such as bayonet-type flange 25a with cut-outs 25 Fig. 3 for receiving and locking the removable jar 21 in position. by relative rotation. The member 20 also has a boss comprising two relatively rotatable parts 41, 44 of complementary shapes and normally biased e.g. by spring 54 into a misaligned position-Fig. 1-wherein the boss cannot be fitted into a cavity 15 in the housing 10 to couple the shafts 11, 37, but are aligned-Fig. 2-by the operation of locking the jar on the base member, this being to ensure that the blades 39 are enclosed by the jar 21 before they can be driven. Alignment is achieved when lugs 23, Fig. 3, on the jar engage in spaces 34 of subassembly 27 and rotation of the jar rotates boss part 41 relative to part 44 which is held stationary because of its connection via handle 30 to fixed ring member 24. Neoprene ring 31 forms a seal between jar 21 and jar base member 20 and a catch 16 in housing socket 15 and releasable by lever 17 locks the boss in the socket.
