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: An adjustable spacer plate 12 mounts over the US standard screed box 10 thermoplastic opening 14 of 0.125? and creates a 0.090? opening.[This eliminates the need for the user to buy another costly screed box.] For screeding over stencils, the spacer 12 can be flipped to create a zero clearance opening. This allows the thermoplastic to come out only when an opening in the stencil pattern is present. Also, as the die 14 wears down, the spacer can be removed which lets the standard size opening be used as a substitute for the 0.090? opening.

Abstract: The screed box (12) rides coplanar to the road surface (14) by pivoting independently of the thermo striper machine (16). This allows the user to create more uniform lines and reduces unsightly pooling of thermoplastic caused by “rocking” of the screed box (12). A machined shaft (18) attached to the screed box (12) pivots in the pre-tensioned mounting bracket (20) on the thermo striper (16). The screed box (12) pivots axially in this mount (20) when it travels over a surface (14), which may be non-coplanar to the plane created by the three wheel points on the thermo striper (16) as shown in FIGS. 4 and 5. To remove the screed die (12), the pivot mount (20) is relieved of spring (24) tension by pressing down by hand or foot the handle (22) mounted to the pivot (20).

Abstract: A thermoplastic line striper has a shift box assembly (10) which guides the screed box (12) and bead dispenser box (14) to following positions: 1) the deployed position where the screed box (12) is down and screed gate (18) is open and the bead box dispenser wheel is engaged; 2) non-deployed and down on ground where the screed box (12) is down, the screed gate (18) is closed and the bead box (14) dispenser wheel is disengaged; and 3) non-deployed and raised off the ground where the screed box (12) is raised up, the screed gate (18) is closed and the bead box dispenser (14) wheel is disengaged. In this third position, the stick shift (20) is locked for transport mode by hooking it behind hook (22) in shift plate (24).

Abstract: A bead dispenser 10 for use with a line striper controls the amount of beads being dispensed onto a thermal (or other) stripe or marking, minimizing waste by not dropping excessive beads. The bead box 12 is capable of dropping six to ten pounds of beads per one hundred square feet. An adjustable lever 14 with a spring plunger 16 allows the user to choose the glass bead flow rate by simply moving adjuster to one of four settings 18. The adjustable lever 14 is attached to an offset shaft 20 that applies tension to the polyurethane flap 22 when rotated.
