Caterpillar Inc. - Peoria IL

International Classification:

F16D 1106

US Classification:

403 57

Abstract:

An improved braked or snubbed joint assembly for use for supporting a grapple, clam shell or like device, is disclosed. The present braked or snubbed joint assembly includes a first member including an element defining an elongate cylindrical bore therethrough having a central axis, and first and second outwardly tapered or conical convex axial end faces. A second member having first and second arms defining a space therebetween receives the first member, and an axial pin rotatably joins the first member and the second member. The second member includes an element located in the space which has a correspondingly tapered or conical concave axial end face positioned in spaced opposed relation to the first outwardly tapered or conical convex axial end face and the second arm includes an element located in the space which has a correspondingly tapered or conical concave axial end face positioned in spaced opposed relation to the second outwardly tapered or conical convex axial end face. Frictional brake elements are disposed between the opposed axial end faces for frictionally resisting or braking relative rotation of the first and second members.

US Classification:

144/336000, 283/067000

Abstract:

In a forestry operation, it is desirable to associate certain information, such as size, species, owner, or the like, with individual logs. Logs are normally stored for a time before processing, and an operator must be able to select certain logs meeting predetermined characteristics from the plurality of stored logs. The present invention provides a method and apparatus for labeling logs in such a way that the information associated with each log may be read from a remote location and the operator need not travel to each log to determine the characteristics of that log.
