Abstract
Abstract A trailer the chassis of which is raised so as to allow its running over rough ground, said chassis being pivotally carried by a turret adapted to be lowered down to ground surface when the trailer is stationary and this lowering being associated with a raising of the wheels above ground as provided by jacks engaging bell cranks fitted between the chassis and the wheels. The turret feet are advantageously adjustable separately in a vertical direction and the chassis carries a tiltable frame.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
232 words
A rocket launcher comprising: a. a chassis; b. a rocket supporting and launching platform pivotally mounted on said chassis; c. means for pivoting said platform relative to said chassis about a horizontal axis; d. a turret having a base and a rotatable portion which is rotatablE about a substantially vertical axis relative to said base, said chassis being mounted on said rotatable portion for 360* rotation relative to said base about said substantially vertical axis; e. a pair of wheels rotatably attached to said chassis on opposite sides thereof; f. means for moving said wheels in a vertical plane from (1) a transport position wherein said wheels contact the ground and support said launcher for high ground clearance, to (2) a launching position wherein said wheels are raised above ground level; g. at least three feet supportingly connected to the turret base, each of said feet having vertically adjustable shoes at the lower ends thereof; h. means for vertically adjusting each of said shoes individually; and wherein when said wheels are in said launching position, said chassis, platform and said wheels are adapted to be rotated 360* about said substantially vertical axis and said launcher is supported on the ground by said feet, and when said wheels are in said transport position, said turret and chassis are elevated above the ground to permit movement of said launcher over smooth and rough terrain.

Claim 3
Dependent Claim
40 words
Rocket launcher as defined in claim 1, wherein each wheel is independently supported by a bell crank on a transverse axis of the chassis and made to move by a fluid operated jack resting on a component of the chassis.
Claim 4
Dependent Claim
54 words
Rocket launcher as defined in claim 1, wherein the three feet of the turret are substantially 120 degrees apart and wherein one of the feet is forward on the longitudinal axis of the launcher while the other two feet are to the rear and on a line parallel to the rear of the chassis.
Claim 5
Dependent Claim
25 words
A launcher as defined in claim 1 wherein the means for pivoting said platform include at least one fluid operated jack secured to said chassis.
Claim 6
Dependent Claim

A launcher as defined in claim 4 wherein the means for adjusting each of the shoes is a fluid operated jack.
Claim 7
Dependent Claim
33 words
A launcher as defined in claim 4 including a sighting telescope mounted on the chassis and a scale mounted adjacent to said jack to define the angle of orientation of said launching platform.
Claim 8
Dependent Claim
40 words
A launcher as defined in claim 1 wherein the means for moving the wheels in a vertical plane comprises an oleopneumatic system, said system also being a suspension system for said launcher when said wheels are in said transport position.
Claim 9
Dependent Claim
56 words
A launcher as defined in claim 1 wherein said substantially vertical axis is longitudinally displaced from a true vertical axis through the point of contact of said wheels with the ground when said wheels are in said transport position and wherein said substantially vertical axis is tilted slightly from the vertical in a vertical longitudinal plane.
