Abstract
Abstract The specification discloses a paint spray booth adapted to provide radiant heat to an object in preparing the object for painting. The booth chamber includes a structure for housing a vehicle or other objects to be painted with tubing fixed in surface contact with the sides of the structure. A system for circulating a heated fluid, such as water, through the tubes is provided to thereby heat the walls of the structure. The heated fluid is circulated through the tubing being heated by a boiler unit and driven by a standard pump acting in conjunction with a thermostat and the boiler. The tubing in the walls is insulated to direct radiant heat into the structure whereby the object to be painted is heated and kept at an optimum drying temperature.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
108 words
A paint chamber for applying radiant heat to an object to prepare the object for painting comprising: a structure for housing the object to be painted; tubing fixed in surface contact with the outside of at least one wall of said structure; means for circulating a heated fluid through said tubing to thereby heat the wall of said structure in which said tubing is in contact; and means for insulating the outside of the wall of said structure in which said tubing is in contact to attach said tubing to said wall and to direct radiant heat into said structure whereby the object to be painted is heated.
Claim 2
Dependent Claim
108 words
A paint chamber for applying radiant heat to an object to prepare the object for painting comprising: a structure for housing the object to be painted; tubing fixed in surface contact with the outside of at least one wall of said structure; means for circulating a heated fluid through said tubing to thereby heat the wall of said structure in which said tubing is in contact; and means for insulating the outside of the wall of said structure in which said tubing is in contact to attach said tubing to said wall and to direct radiant heat into said structure whereby the object to be painted is heated.
Claim 3
Dependent Claim
41 words
The spray chamber according to claim 1 wherein said tubing is formed in a serpentine configuration along substantially the full height of the wall of the structure to increase the surface contact between said tubing and the wall of said structure.
Claim 4
Dependent Claim
18 words
The spray chamber according to claim 1 wherein said means for insulating said tubing and walls is polyurethane.
Claim 5
Dependent Claim
167 words
A paint chamber for applying radiant heat to an object to prepare the object for painting comprising: a structure for housing the object to be painted; tubing fixed in surface contact with the outside of at least one wall of said structure; said tubing including a feeder line; an exhaust line; a plurality of section lines communicating between said feeder line and said exhaust line, said section lines being spaced longitudinally along said structure; valve means within said section lines for restricting the flow of fluid through each section line whereby the heat emitted from each section line may be regulated; means for circulating a heated fluid through said tubing to thereby heat the wall of said structure in which said tubing is in contact; and means for insulating the outside of the wall of said structure in which said tubing is in contact to attach said tubing to said wall and to direct radiant heat into said structure whereby the object to be painted is heated.
Claim 6
Dependent Claim
167 words
A paint chamber for applying radiant heat to an object to prepare the object for painting comprising: a structure for housing the object to be painted; tubing fixed in surface contact with the outside of at least one wall of said structure; said tubing including a feeder line; an exhaust line; a plurality of section lines communicating between said feeder line and said exhaust line, said section lines being spaced longitudinally along said structure; valve means within said section lines for restricting the flow of fluid through each section line whereby the heat emitted from each section line may be regulated; means for circulating a heated fluid through said tubing to thereby heat the wall of said structure in which said tubing is in contact; and means for insulating the outside of the wall of said structure in which said tubing is in contact to attach said tubing to said wall and to direct radiant heat into said structure whereby the object to be painted is heated.
Claim 7
Dependent Claim
45 words
The spray chamber according to claim 4 wherein said section lines are formed in a serpentine arrangement to extend back and forth over at least one wall of said structure thereby increasing the surface contact between said section lines and the wall of said structure.
Claim 8
Dependent Claim
44 words
The spray chamber according to claim 5 wherein said feeder line and said exhaust line extend around the perimeter of the structure and said section lines are attached in surface contact with the outer surface of a plurality of the walls of said structure.
Claim 9
Dependent Claim
123 words
A paint chamber for applying radiant heat to an object in preparation for painting, comprising: a spray booth for housing the object to be painted; tubing including a feeder line and an exhaust line extending along the perimeter of said spray booth; a plurality of section lines attached between said feeder line and exhaust line and attached along the outer surface and in surface contact with at least one wall of said spray booth; pump means for circulating a heated fluid through the tubing and section lines to heat the walls of said spray booth; insulation means for covering the outer surface of the walls of said spray booth and the tubing and section lines to direct radiant heat into the spray booth.
Claim 10
Dependent Claim
123 words
A paint chamber for applying radiant heat to an object in preparation for painting, comprising: a spray booth for housing the object to be painted; tubing including a feeder line and an exhaust line extending along the perimeter of said spray booth; a plurality of section lines attached between said feeder line and exhaust line and attached along the outer surface and in surface contact with at least one wall of said spray booth; pump means for circulating a heated fluid through the tubing and section lines to heat the walls of said spray booth; insulation means for covering the outer surface of the walls of said spray booth and the tubing and section lines to direct radiant heat into the spray booth.
Claim 11
Dependent Claim
42 words
The paint chamber according to claim 7 further comprising: a restrictor valve in each of said section lines permitting the control of the flow of heated fluid through each section line whereby the heat emitted from each section line may be regulated.
Claim 12
Dependent Claim
50 words
The paint chamber according to claim 7 wherein said tubing extends around the perimeter of said spray booth and said section lines are formed in a serpentine configuration substantially along the full height of the outer surface and in surface contact with a plurality of walls of said spray booth.
Claim 13
Dependent Claim
