CENTRAL MULTI DIRECTIONAL TRANSMISSION SYSTEM
First Claim
1. A dual chassis frame with multi-directional transmission comprising:
- a) a rear chassis frame assembly;
b) a front chassis frame assembly;
c) a central multi-directional mechanism connecting a medial portion of said front chassis to a medial portion of said rear chassis to selectively allow for the independent horizontal and vertical movement of said front and rear chassis when traversing uneven terrain;
d) a pair of hydraulically retractable central bars to selectively connect said front chassis to said rear chassis to form a unified, stable rigid chassis;
e) a pair of fixed wheels disposed on a rear portion of said rear chassis and a pair of wheels disposed on a front portion of said front chassis; and
g) means for increasing the distance between said front chassis and said rear chassis during dual chassis operation.

Abstract
A dual chassis with multi-directional transmission includes a front chassis and a rear chassis that can be united to function as a traditional unitary chassis or can be separated to become two independently, but connected, chassis that can traverse uneven terrain during ground movement. The multi-directional transmission serves to increase the distance between the two chassis and enable them to travel at differing vertical and horizontal angles with respect to the surface of the earth. As part of the multi-directional transmission, a central multi-directional mechanism connects a medial portion of said front chassis to a medial portion of said rear chassis to selectively allow for the independent horizontal and vertical movement of said front and rear chassis when traversing uneven terrain.

13. A dual chassis frame with multi-directional transmission, comprising:
-
a) a rear chassis frame assembly; b) a front chassis frame assembly; c) a pair of hydraulically retractable central bars to selectively connect and disconnect said front chassis and said rear chassis to form a unified, stable rigid chassis to a independently movable, yet coupled multi-directional front chassis and rear chassis, wherein said rear chassis frame assembly comprises side frame members having a means for securing said central bars to said rear chassis frame assembly, wherein said means for securing said central bars is a pair of pressure locks; d) a central multi-directional mechanism connecting a medial portion of said front chassis to a medial portion of said rear chassis to selectively allow independent horizontal and vertical movement of said front and rear chassis for traversing uneven terrain when said front chassis and rear chassis are disconnected from each other by said hydraulically retractable central bars; e) a pair of fixed wheels disposed on a rear portion of said rear chassis and a pair of wheels disposed on a front portion of said front chassis; and f) means for increasing the distance between said front chassis and said rear chassis during dual chassis operation. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A method for using a dual chassis frame with multi-directional transmission including a rear chassis frame assembly, a front chassis frame assembly, a multi-directional mechanism connecting a medial portion of said front chassis to a medial portion of said rear chassis to selectively allow for the independent horizontal and vertical movement of said front and rear chassis when traversing uneven terrain, a pair of hydraulically retractable central bars and pressure locks to selectively connect said front chassis to said rear chassis to form a unified, stable rigid chassis and selectively disconnect said front chassis from said rear chassis to allow independent horizontal and vertical movement of said front and rear chassis, a pair of fixed wheels disposed on a rear portion of said rear chassis and a pair of wheels disposed on a front portion of said front chassis, and a central hydraulic piston with a movable portion comprising a hexagonal bar for increasing the distance between said front chassis and said rear chassis during dual chassis operation, wherein said dual chassis frame is placed into dual chassis mode by the following functions:
-
a) releasing said pressure locks; b) retracting said central bars; c) releasing said disc brake; and d) extending said central hydraulic piston thereby effectively extending said hexagonal bar and said central multi-directional mechanism to increase the distance between said front chassis and said rear chassis.
