Appl. No.:

7/066743

Inventors:

Thomas R. Brown - Plainfield IL
Ronald C. Natzke - Burlington IA
Richard H. Logan - West Burlington IA

Assignee:

J. I. Case Company - Racine WI

International Classification:

G05G 104
G05G 518

US Classification:

74491

Abstract:

An improved adjustable control device for multi-lever hydraulic controls on earth-moving equipment, which conveniently and easily positions the control levers to accommodate different operators. The device includes a pair of spaced supports, a pair of axially aligned end members each movably mounted on one of the supports, a main shaft extending between the end members used for pivot mounting of the levers, and a device to adjust the end members on the supports. Parts are positioned and arranged such that end member adjustment moves the main shaft vertically, which in turn moves the range of control lever motion force or aft as desired.

Abstract:

An anti-theft security system for an off-road vehicle is disclosed. The system includes a master control module, which may be part of the vehicle's instrument cluster, and a remotely located security module, which is directly adjacent to at least one electrically-operated actuator of the vehicle normally operated as part of transporting the vehicle to another location. The security module includes a tamper-resistant housing which obstructs physical access to at least part of the actuator. The master module, which may include a microprocessor and LED display, has an operator interface such as a keypad for entering a first access code known only to authorized operators of the vehicle. When the sequence of entered keystrokes matches the first access code stored within the master module, the module automatically generates and transmits to the security module a signal containing a second and different access code. When the security module determines that the received signal is coded with the same second access code stored within its memory, a power switch within the security module is energized, thereby providing electrical power to the actuator so that the vehicle may be moved.
