Hand-held wand mixer

InactiveUS6974244B1Easily remove and exchangeLoad be therefore reducedRotary stirring mixersMixer accessoriesHand heldDrive shaft
A wand mixer having a wand assembly that is detachable from the motor assembly as a single unit. The wand assembly includes a drive shaft that is enclosed within a tubular housing having a seal at the lower end for preventing entry of fluids and debris. First and second bearings at the ends of the tubular housing support both ends of the shaft so as to prevent deformation and damage of the seal when the wand assembly is removed from the motor assembly for cleaning. The wand assembly mounts to the motor assembly using a bayonet-type connection, and the motor and drive shafts are interconnected by an externally splined member that is received axially in an internally splined sleeve. The wand assembly can therefore be removed or mounted to the motor assembly by a convenient, manual turning and axial movement of the components.

Timing gear flexible coupling

The invention is a timing gear flexible coupling for operation of a disc valve rotatively mounted in an internal combustion engine cylinder head. Rotation of the disc valve periodically opens and closes a plurality of exhaust and intake ports in the stationary stator of the cylinder head in a sequential manner corresponding to the alternating order of the engine of the engine thermodynamic pressure cycle. The purpose of the flexible coupling is to momentarily slow the rotational velocity of the disc valve during the highest peak pressure of the engine combustion stroke during the ignition spike which exponentially reduces the rubbing contact frictional energy between the disc and stator. The primary purpose of the timing gear flexible coupling is to reduce the shearing impact across the lubricating film at the sliding interface between the disc valve and stationary stator comprising the engine intake and exhaust ports thereby decreasing frictional surface wear and permitting faster engine acceleration.
