Abstract:
An adjustable spacer plate mounts over the US standard screed box thermoplastic opening 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 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 wears down, the spacer can be removed which lets the standard size opening be used as a substitute for the 0. 090″ opening.

Abstract:
This invention allows a painter to use a sprayer to reach objects or surfaces that would otherwise be out of reach for them. A step is provided on the sprayer which provides a quick and easy solution for users when prepping and cleaning a room. This feature would easily allow an average sized man to reach the ceiling in an 8 foot room and other similar heights. In this function the step would allow the sprayer frame to act as a step stool or step ladder.

Abstract:
The striper has an aluminum die trough and doctor gate components having a black anodized Type 2 Class 2 coating. Other components of the screed box which are not intended to transfer hear are coated with a reflective E-nickel. These components are more likely to be use to lift the screed box and will absorb less heat due to their reflective properties.

US Classification:
404 93
Abstract:
A thermoplastic line striper has a shift box assembly () which guides the screed box () and bead dispenser box () to following positions: 1) the deployed position where the screed box () is down and screed gate () is open and the bead box dispenser wheel is engaged; 2) non-deployed and down on ground where the screed box () is down, the screed gate () is closed and the bead box () dispenser wheel is disengaged; and 3) non-deployed and raised off the ground where the screed box () is raised up, the screed gate () is closed and the bead box dispenser () wheel is disengaged. In this third position, the stick shift () is locked for transport mode by hooking it behind hook () in shift plate ().

Abstract:
A bead dispenser 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 is capable of dropping six to ten pounds of beads per one hundred square feet. An adjustable lever with a spring plunger allows the user to choose the glass bead flow rate by simply moving adjuster to one of four settings The adjustable lever is attached to an offset shaft that applies tension to the polyurethane flap when rotated.

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

International Classification:
E01C 23/20
US Classification:
404 94
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.
