9D-HL-14098 LUBRICATION SYSTEM FOR TRANSMISSION OF AUTOMATIC CLOTHES WASHING MACHINE ABSTRACT OF THE DISCLOSURE A lubrication system for the transmission of an automatic clothes washing machine is provided which includes a generally vertical hollow shaft arranged to be driven from the transmission. An oil pump includes a cup mounted on the lower end of the shaft for rotation therewith, and a piston slidably positioned on the shaft and receivable within this cup. The piston is arranged for sliding movement on the shaft, but is prevented from rotating with the shaft. The piston is biased toward the cup by a spring positioned on the shaft. The piston is formed to provide an inlet port on the outer wall thereof, and an outlet port on the inner wall, the outlet port being positioned in com- munication with a passage to the interior of a hollow shaft at predetermined intervals during rotation of the shaft. The cup and piston have engaging cam faces formed to cause the piston to move along the shaft against the bias of the spring during a portion of the cycle of rotation of the shaft to open the inlet port and further formed to provide abrupt return move- ment of the piston toward the cup under the influence of the biasing means to close the inlet port and force lubricant through the outlet port into the hollow interior of the shaft. The lubricant is pumped to the top of the hollow shaft and then distributed to the portions of the transmission requiring lubrication.
