The steering system comprises a handlebar rotatable to steer a wheel, and a speed bar pivotable to control the propulsion system.

Abstract: A mobile thermoplastic applicator comprises a kettle, a main gas burner, a heat exchanger plenum, and a screed die box. The kettle has walls which define an interior space for melting thermoplastic. The main gas burner is situated beneath the kettle, and is configured to heat the kettle. The heat exchanger plenum is situated inside the thermoplastic kettle and is configured to subdivide the interior space and circulate heated air from the main gas burner. The screed die box is configured to receive molten thermoplastic from the kettle and deposit that molten thermoplastic on a surface.

Abstract: A screed die box includes a screed die bucket, a screed die box gate, a screed die box lever, a screed plate, and a positioning member. The screed die box gas is slidably connected at the bottom of the screed die bucket. The screed die box lever is rotatably connected to the screed die bucket and the screed die box gate for sliding the screed die box gate between an open position and a closed position. The screed plate is slidably connected along an aft side of the screed die bucket and includes a positioning aperture. The positioning member is located in the screed die bucket and engages the screed plate, the positioning member sliding the screed plate as the positioning member is rotated.

Abstract: A flame safety system for a thermoplastic applicator comprises a gas burner and a flame indicator. The gas burner expels a jet of pressurized combustible gas from an outlet nozzle, and includes an attachment groove near the nozzle. The flame indicator includes an attachment ring configured to fit into the groove, thereby securing the flame indicator to the gas burner, and a flame path portion extending from the attachment ring into the jet of pressurized combustible gas. The flame path portion is formed from a material which incandescently glows whenever the jet of combustible pressurized gas is lit.

Abstract: A hose reel swivel (10), comprising a shaft (20) having a fluid passage therein, a swivel housing (22) rotatable about said shaft (20) and a plurality of UHMWPE with fluorocarbon o-ring energized seals (24) located between said shaft (20) and said swivel housing (22). The hose reel swivel (10) allows the user to coil a hose (12) with a reel (14) and store on a paint sprayer (16). This eliminates having to coil a hose by hand, which reduces the time to coil the hose, eliminates hose kinks and stores a coiled hose more compactly and securely. The swivel design provides longer life.
