Patent number: 5676221Abstract: A gear case assembly and lubricant retaining device therefore wherein the assembly includes a gear case having a hub and/or shaft receiving opening therein and a lubricant retaining device extending toward the interior of said case to reduce lubricant flow through said opening. A part of said lubricant retaining device acts as a diverter to restrict lubricant flow toward said opening and consequential potential losses therethrough.Type: GrantFiled: June 6, 1996Date of Patent: October 14, 1997Assignees: Carol Ann Mackay, Helen Lou KurtzInventors: Richard J. Renk, Richard M. Ebert
-
Patent number: 5255815Abstract: The cap is for use in closing the end of an opening as may be provided in a container. The cap has an elastomeric top which is deflectable by a presser plate urged toward the top and opening by a biasing spring. Deflection of the elastomeric top enables the cap to seat and adjust around the opening and accommodate variances therein.Type: GrantFiled: December 19, 1990Date of Patent: October 26, 1993Assignees: Carol Ann Mackay, Helen Lou KurtzInventors: Richard J. Renk, Richard M. Ebert
-
Patent number: 5123297Abstract: A resilient sealing device is provided for accommodating tolerance variations between a lubricant holding case and a hub member. The device has a sealing face including deformable lips which are urged toward the hub by a resilient column and deformable legs held in a retaining channel, with both the column and the legs allowing the lips to recede back into the channel while the edges of the sealing face are held by the edges of the channel.Type: GrantFiled: September 20, 1989Date of Patent: June 23, 1992Assignees: Carol Ann Mackay, Helen Lou KurtzInventors: Richard J. Renk, Richard M. Ebert
-
Patent number: 5082089Abstract: A device for applying lubricant to a rotatable journal having a lubricating body is biased for movement toward the journal along a defined path. Movement of the lubricating body toward the journal is controlled by a low wear, fast-disconnect retaining mechanism.Type: GrantFiled: November 14, 1988Date of Patent: January 21, 1992Assignees: Carol Ann Mackay, Helen Lou KurtzInventors: Richard J. Renk, George E. Boller, Richard M. Ebert
-
Patent number: 5038631Abstract: A device for restricting the flow of lubricant from a locomotive traction motor gear case and along an armature drive shaft of the traction motor and into the drive shaft's bearing mounting assembly, portions of which extend into the gear case. The device may also restrict lubricant flow into a return drain port of the drive shaft's bearing mounting assembly as a result of gear generated splash within the case.Type: GrantFiled: November 24, 1989Date of Patent: August 13, 1991Assignees: Carol Ann Mackay, Helen Lou KurtzInventors: Richard J. Renk, George E. Boller, Richard M. Ebert
