Abstract
Abstract Disclosed is a truck with a tube bender mounted on the rear and enclosed in a body which also provides storage for mufflers and tail pipes. The tube bender is pivotally mounted so it can be swung from a storage position normal to the body longitudinal axis outward to position near alignment with the body longitudinal axis for use. The body portion which surrounds the bender opens on three sides to cooperate with the pivotal movement of the bender in permitting the forming of tail pipe configurations without interference from the body.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
141 words
A mobile muffler shop comprising: a mobile chassis; a body mounted on said Chassis and having a pair of oppositely disposed body sides and a pair of oppositely disposed body ends; a tube bender having a proximal end mounted in said body adjacent a first of said body ends, and a distal end with bending jaws, said tube bender being pivotally mounted on said chassis for swinging movement from a stowed position with said bender extending between said body sides to a variety of work positions with said distal end extended outwardly beyond said first body end; and storage compartments formed in said body adjacent said tube bender and disposed to store muffler supplies, said storage compartments being positioned to avoid interference with a tail pipe disposed in said tube bender bending jaws, when said bender is in said work positions.
Claim 2
Dependent Claim
141 words
A mobile muffler shop comprising: a mobile chassis; a body mounted on said Chassis and having a pair of oppositely disposed body sides and a pair of oppositely disposed body ends; a tube bender having a proximal end mounted in said body adjacent a first of said body ends, and a distal end with bending jaws, said tube bender being pivotally mounted on said chassis for swinging movement from a stowed position with said bender extending between said body sides to a variety of work positions with said distal end extended outwardly beyond said first body end; and storage compartments formed in said body adjacent said tube bender and disposed to store muffler supplies, said storage compartments being positioned to avoid interference with a tail pipe disposed in said tube bender bending jaws, when said bender is in said work positions.
Claim 3
Dependent Claim
81 words
A mobile muffler shop as described in claim 1, in which: said pivotal mounting is so disposed with respect to said bender and said body that said bender is pivotally movable from a stowed position laterally disposed with respect to said body and substantially centered between said body sides, to a variety of work positions including a position longitudinally aligned with said body with more than half the length of said bender projecting rearward of said first end of said body.
Claim 4
Dependent Claim
50 words
A mobile muffler shop as described in claim 2, in which: said work positions of said bender further include a position wherein an acute angle is formed between straight lines from the bending jaws of said bender to the most laterally extended portions on each side of said storage compartments.
Claim 5
Dependent Claim
50 words
A mobile muffler shop as described in claim 1, in which: said mobile chassis includes a truck having a load capacity of one ton or less; and which further includes a hydraulic drive system for driving said tube bender including a hydraulic pump driven from the transmission of said truck.
