Screed die pivot removal system

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 ).

1 . In a thermo line striper having a direct of travel and a screed box, the improvement comprising a screed box mount allowing pivoting of said screed box along an axis parallel to said direction of travel in order to closely follow the surface under said screed box.
