Abstract
Abstract A chassis having a walking beam undercarriage suspends a carrier in an adjustable manner. The carrier is confined for vertical travel by chassis mounted guides and serves to carry a series of liner members defining multiple burning chambers. Each chamber is served by a low pressure oil burner and exhausts a heat flow downwardly against the passing ground surface. The liner members are detachably mounted by knock-out pins for purposes of periodic servicing the carrier. Repositionable wheel assemblies on the walking beam undercarriage permit travel of the chassis in one direction during operation and lengthwise travel for passage over roadways.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
142 words
A heat generating apparatus for imparting elevated temperatures to the ground and the area immediately there below, said apparatus comprising, a wheel supported chassis, an elongate carrier of wall construction depending from said chassis and defining pin receiving openings, a series of segmented metallic liner members removably mounted in pairs interiorly along the carrier structure and defining multiple downwardly opening burning chambers, said liner members including bosses defining openings for the reception of removable pins interconnecting the liner members to the carrier structure, each pair of liner members additionally including mutually abutting flanges, burners for discharging a pressurized fuel-air mixture into each of said burning chambers, and pin means coupling a liner member with a wall of said elongate carrier, said pin means in removable engagement with said wall and liner member to permit convenient removal and replacement of a liner member.
Claim 2
Dependent Claim

A heat generating apparatus for imparting elevated temperatures to the ground and the area immediately there below, said apparatus comprising, a wheel supported chassis, an elongate carrier of wall construction depending from said chassis and defining pin receiving openings, a series of segmented metallic liner members removably mounted in pairs interiorly along the carrier structure and defining multiple downwardly opening burning chambers, said liner members including bosses defining openings for the reception of removable pins interconnecting the liner members to the carrier structure, each pair of liner members additionally including mutually abutting flanges, burners for discharging a pressurized fuel-air mixture into each of said burning chambers, and pin means coupling a liner member with a wall of said elongate carrier, said pin means in removable engagement with said wall and liner member to permit convenient removal and replacement of a liner member.
Claim 3
Dependent Claim
67 words
The apparatus claimed in claim 1 additionally including a walking beam type undercarriage at each end of said chassis, wheel assemblies mounted adjacent the end of each walking beam undercarriage, a pivotal connection between each undercarriage and its respective end of said chassis, yieldable means interposed between each undercarriage and said chassis to maintain the chassis against fore and aft tipping forces acting about the pivotal connections.
Claim 4
Dependent Claim
28 words
The apparatus claimed in claim 2 wherein each undercarriage includes spindle plates positionable and lockable through 90° to permit alternative travel of the chassis along perpendicularly oriented courses.
