ABSTRACT:
A mobile applicator for roofing tar having advance spray nozzles followed by spreader brushes carried on a wheeled motorized chassis which also supports a tar hopper which is maintained in heated condition and agitated by the exhaust of an internal combustion engine which drives the apparatus, the engine exhaust being selectively ported to heat the hopper or to by pass the same when the liquid tar becomes sufficiently hot to prevent overheating and also to maintain the lines from the hopper to the spray hot to prevent solidification of the sealant, viz., the tar.
