Adjustable Lip Type Seal For A Crankshaft
US Patent:
4021049, May 3, 1977
Filed:
Dec 15, 1975
Appl. No.:
5/640512
Inventors:
Elmer B. Phelps - Creve Coeur IL
Allen J. Friede - Peoria IL
Allen J. Friede - Peoria IL
Assignee:
Caterpillar Tractor Co. - Peoria IL
International Classification:
F16J 1516
US Classification:
277 11
Abstract:
A lip seal assembly provides an axially adjustable seal between a rotating shaft, such as a crankshaft, and a stationary housing, such as an engine block. The assembly includes a generally ring shaped retainer circumscribing the shaft and having a hollow, cylindrical cavity therein which receives a slidably positioned lip seal mounting member. A plurality of ring shaped spacer gaskets enable the lip seal to be axially adjusted within the cavity such that the point of engagement of the lip seal with a running surface of the shaft may be changed.
Dampener For Impacting Mechanism
US Patent:
4867253, Sep 19, 1989
Filed:
Oct 14, 1988
Appl. No.:
7/257608
Inventors:
Larry G. Eftefield - Edelstein IL
Elmer B. Phelps - Creve Coeur IL
Elmer B. Phelps - Creve Coeur IL
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
B25D 1724
US Classification:
173124
Abstract:
A dampener for cushioning engagement forces of an impacting mechanism. An impacting mechanism has relatively movable members that can be releasably coupled together. The coupling engagement produces forces which tend to deform the coupling members. An impacting mechanism, having an actuator with a releasable coupling member is coupled to a relatively movable impact plunger, contains a dampener which compresses or deforms to cushion the coupling force. An impacting mechanism having a dampener for cushioning the forces during coupling engagement prevents the coupling members from being deformed.
