Abstract
Abstract The turbine of an automotive torque converter is rotated while its casing is held stationary and solvent is introduced into the converter, thereby to effect a reverse flushing action to remove deposit and potentially injurious particles from the interior of the converter. An adapter fits over and seals upon the converter hub and the upper end of the adapter is provided with a sealed bearing journaling the splined turbine drive shaft, solvent being introduced into the converter through the adapter. An overhead drive is provided for the turbine drive shaft and a single motor is used simultaneously to drive the turbine shaft and a pump for circulating the solvent.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
201 words
A machine for cleansing automotive-type torque converters, comprising in combination, a frame having a well for receiving a supply of solvent liquid and including a support over said well upon which a torque converter may be disposed, said frame including an overhead support having a portion overlying and spaced above said well, drive means carried by said overhead support and including a coupling shaft axially shiftable toward and away from a torque converter supported on said frame over said well, pump means for circulating solvent liquid, means for driving said pump means and said drive means, an adapter assembly including a sleeve adapted to slip over the hub of a torque converter and a turbine drive shaft adapted to be driven by said coupling shaft, a seal carried by one end of said sleeve for engaging around the torque converter hub, bearing means adjacent the other end of said sleeve journaling said turbine drive shaft coaxially of said sleeve and defining with said seal, a chamber communicating with the interior of the torque converter through the hub thereof, and conduit means connecting said pump means to said well and said chamber for recycling solvent liquid from said well to said chamber.
Claim 2
Dependent Claim
201 words
A machine for cleansing automotive-type torque converters, comprising in combination, a frame having a well for receiving a supply of solvent liquid and including a support over said well upon which a torque converter may be disposed, said frame including an overhead support having a portion overlying and spaced above said well, drive means carried by said overhead support and including a coupling shaft axially shiftable toward and away from a torque converter supported on said frame over said well, pump means for circulating solvent liquid, means for driving said pump means and said drive means, an adapter assembly including a sleeve adapted to slip over the hub of a torque converter and a turbine drive shaft adapted to be driven by said coupling shaft, a seal carried by one end of said sleeve for engaging around the torque converter hub, bearing means adjacent the other end of said sleeve journaling said turbine drive shaft coaxially of said sleeve and defining with said seal, a chamber communicating with the interior of the torque converter through the hub thereof, and conduit means connecting said pump means to said well and said chamber for recycling solvent liquid from said well to said chamber.
Claim 3
Dependent Claim
