Abstract
A device for cleaning and lubricating an exterior surface of an asphalt compacting machine includes a support member removably attached to the machine. Positioned on the support member for easy access are a flexible scraper for cleaning the drum and a fluid spray system, for spraying and uniformly distributing a lubricating fluid onto the drum. Elastic spring means on the support member assures positive contact between the drum and the scraper and between the drum and the fluid distributor.
Claims8
A device for cleaning and lubricating an exterior surface of a drum on an asphalt compacting machine comprising:
- a. support member means removably attached to the machine, for supporting a cleaning means and a lubricating means along the width of the drum and spaced from the drum surface, said support member means including a mounting plate spaced above the surface of the drum;
- b. fluid spray means mounted on said mounting plate, for spraying a lubricating fluid onto the surface of the drum;
- c. flexible absorbent mat means mounted on said mounting plate, extending along the width of the drum, for contacting the surface of the drum, to spread fluid from said spray means in a uniform distribution on the drum surface;
- d. flexible scraper blade means mounted on said mounting plate, extending along the width of the drum, for contacting the surface of the drum, to remove debris adhering to the drum surface;
- e. first elastic spring means on said support member, for resiliently urging said scraper blade means into contact with the drum surface;
- and
- f. second elastic spring means on said mounting plate, for resiliently urging said flexible absorbent mat means into contact with the drum surface.
