Abstract
Apparatus for applying foamed plastic material on a roof deck comprises a wheeled frame moveable along the deck and carrying a foamed plastic dispenser support and drive assembly which extends transverse to the direction of movement of the frame and which includes a carriage reciprocable in opposite directions along a linear carriage path and supporting a foamed plastic dispenser for reciprocation therewith and for pivotal displacement relative thereto at each of the opposite ends of the carriage path about a horizontal axis transverse to the carriage path so as to pivot the dispenser for discharging the foamed plastic material laterally outwardly of the ends of the support and drive assembly.

In apparatus for applying foamed plastic material on a substrate comprising an expandable plastic foam material dispenser having a dispensing axis, a frame, means for relatively displacing said frame and said substrate in a given direction, dispenser support means supporting said dispenser on said frame for reciprocation relative thereto in laterally opposite directions with respect to said given direction and for said dispensing axis to be oriented for directing expandable plastic foam material downwardly onto said substrate, and means for reciprocating said dispenser in said laterally opposite directions and between direction reversing locations in said opposite directions, the improvement comprising:
- said dispenser support means comprising a carriage supporting said dispenser and carriage support means supporting said carriage for displacement in said laterally opposite directions along a linear carriage path, and means interengaging at each of said direction reversing locations for pivoting said dispenser relative to said carriage about a horizontal axis parallel to said given direction for shifting said dispensing axis laterally outwardly of said carriage at the corresponding direction reversing location.
Apparatus for applying foamed plastic material on a substrate comprising an expandable plastic foam material dispenser having a dispensing axis, a wheeled frame for displacement relative to said substrate along a path of movement, a dispenser support and drive assembly on said frame for movement therewith and extending transverse to said path of movement, said support and drive assembly having opposite ends and including a carriage, carriage track means supporting said carriage for sliding displacement in opposite directions along a linear carriage path between said ends, means for reciprocating said carriage in said opposite directions and between direction reversing locations adjacent said opposite ends, dispenser mounting means mounting said dispenser on said carriage for displacement therewith along said carriage path with said dispensing axis in a vertical plane transverse to said carriage path and for pivotal displacement of said dispenser relative to said carriage, and means adjacent each of said opposite ends of said support and drive assembly interengaging with said dispenser mounting means to pivot said dispenser about a horizontal pivot axis transverse to said carriage path for deflecting said vertical plane of said dispensing axis outwardly of the corresponding one of said opposite ends.
