Abstract
A lightweight manually maneuverable, quick-drying paint striper for painting stripes on pavements, in which the hot exhaust gas of an internal combustion engine driving a paint pressurizing unit for the system is used to heat the paint by passing it through a heat exchanger to establish a temperature and viscosity appropriate for painting stripes with an air nozzle or airless nozzle. When an air nozzle is used, the air is heated by the exhaust gas in the same or another heat exchanger in a manner similar to that in which the paint is heated in the exchanger.
Claims15
A portable manually maneuverable paint striper for striping pavements comprising;
- a carriage on which the components of said striper are mounted,
- said carriage having a handle for maneuvering said striper for placement of a stripe on a pavement,
- a striping nozzle for application of paint stripes to a pavement over which said striper is maneuvered,
- said components comprising a paint reservoir for paint supplied to said nozzle,
- a pressure unit for pressurizing paint supplied to said nozzle,
- an internal combustion engine mechanically connected to drive said pressure unit,
- a heat exchanger connected to receive hot exhaust gas of said engine and including a heat receptive passage within said heat exchanger for supply of paint therethrough heated by said hot exhaust gas,
- said passage in heated condition as heated by said hot gas being effective to provide the heat required for striping the paint supplied therethrough to said nozzle,
- said passage being connected directly to said nozzle for striping the paint passed therethrough.
A portable manually maneuverable paint striper for striping pavements comprising
- a reservoir of paint for said striper,
- a stripe producing nozzle,
- a pressure unit for application of pressure to said reservoir to effect supply of paint from said reservoir to said nozzle,
- an internal combustion engine for driving said pressure unit,
- a heat exchanger including a passage therethrough through which the paint supplied to said nozzle is passed, and
- means for supply of exhaust gas of said engine to said heat exchanger to heat the paint passed therethrough.
A method of providing a lightweight manually maneuverable paint striping system for striping pavement by reducing the number of components required comprising;
- feeding paint from a source in a paint supply system to a striping nozzle,
- supplying of flow pressure from a pressurizing unit to the paint in said system,
- supplying driving power to said pressure unit from an internal combustion engine,
- supplying the hot exhaust gas of said engine to a heat exchanger,
- passing the paint in said system through a heat recptive passage in said heat exchanger to effect heating of said paint with said exhaust gas and
- thereupon directly feeding the hot paint to said nozzle for striping said paint,
- thereby substantially eliminating the need for a separate component for heating of paint fed to said nozzle.
