Abstract
A tow point for an asphalt paver, which allows the operator to: (1) select either a fixed or sliding tow point connection; and (2) select from among several possible locations of each, thereby adjusting the distance between the screed and transverse auger of the paver. Combination of these features in a single machine makes it possible to lay down an asphalt mat of uniformly desired thickness, while optimizing use of the aggregate batch particles.
Claims12
A tow point assembly for a finishing paver having a traction unit for providing motive force, a screw auger for laterally distributing paving material onto a roadbed, and a floating screed for leveling and compressing the paving material into a compacted mat, the tow point assembly, comprising:
- (a) a leveling arm extending forward from the floating screed and having a forward end bearing aperture means;
- a row point plate connected to the traction unit and having a rear end bearing aperture means which slideably engages the forward end of said leveling arm;
- and
- (c) fastening means for connecting the forward end of said leveling arm and the rear end of said tow point plate together in a manner such that they may be adjusted into either fixed or sliding connection, and they may be horizontally adjustably engaged prior to such connection so that a selectively variable horizontal distance between the floating screed and the auger is obtained.
A tow point assembly for a finishing paver having a traction unit for providing motive force, a screw auger for laterally distributing paving material onto a roadbed, and a floating screed for levelling and compressing the paving material into a layered mat, the tow point assembly, comprising:
- (a) a leveling arm extending forward from the floating screed, and having attached to a forward end thereof sleeve means;
- (b) a tow point plate connected to the traction unit, and having pivotably connected to its rear end thereof a shaft having a plurality of apertures therein, said shaft slideably engaging said sleeve means;
- and
- (c) containing means for restricting movement of said sleeve means along said shaft in a manner such that they may be adjusted into either fixed or sliding connection and they may be horizontally adjustably engaged prior to such connection so that a selectively variable horizontal distance between the floating screed and the auger is obtained.
