Apparatus for forming paved channels

Claim 2

Apparatus for forming paved channels comprising: a hopper section for containing asphaltic composition paving material; a forward wheel section pivotally connected to the hopper section, extending forwardly therefrom, and mounting the hopper section for movement along a predetermined path to be paved; a rearward heater and spreader section pivotally connected to the hopper section, extending rearwardly therefrom and being in communication therewith to receive material therefrom; means in said heater and spreader section for heating and forming said material therein and discharging it in predetermined formed shape onto said path; and means interconnecting said heater and spreader section and its pivotal connection to the hopper section for raising and lowering the heater and spreader section to adjust the proximity thereof to the surface of the path.

Claim 3

Apparatus for forming paved channels comprising the structure claimed in claim 1: in which the last named means comprises a lifting and lowering jack disposed at each opposite rear end corner of the heater and spreader section, and adapted to be independently operated to apply adjusting fore selectively to either side of said section.

Claim 4

Apparatus for forming a paved channel comprising: a ground-engaging support means; a material-dispensing hopper mounted thereon; channeling means operatively connected to said hopper for receiving material dispensed therefrom comprising: a pair of laterally spaced relatively high tunnel structures; an intervening relatively low center section; and said structures and section terminating in an orifice plate vertically disposed at the rear end of the apparatus and having a discharge configuration for forming curbs from material from the tunnel structures and for forming a connecting center pavement from material from the center section; and heating burner means mounted on said center section having flues connected in heating relation to said center section and said tunnel structures for fluidizing material therein and facilitating its discharge in formed configuration from the orifice plate.

Claim 5

Apparatus for forming a paved channel comprising: a ground-engaging support means; a material-dispensing hopper mounted thereon; channeling means operatively connected to said hopper for receiving material dispensed therefrom comprising: a pair of laterally spaced relatively high tunnel structures; an intervening relatively low center section; and said structures and section terminating in an orifice plate vertically disposed at the rear end of the apparatus and having a discharge configuration for forming curbs from material from the tunnel structures and for forming a connecting center pavement from material from the center section; and heating burner means mounted on said center section having flues connected in heating relation to said center section and said tunnel structures for fluidizing material therein and facilitating its discharge in formed configuration from the orifice plate.

Claim 6

Apparatus for forming a paved channel as claimed in claim 3, in which said orifice plate is detachable for replacement by other orifice plates having different discharge configurations.

Claim 7

Apparatus for forming a paved channel as claimed in claim 3: in which said channeling means comprises an integrated structure pivotally connected to said hopper; and in combination with jack means connecting said structure with the hopper for adjusting pressure exerted by said structure on the discharging material.

Claim 8

Apparatus for forming a paved channel comprising: a ground-engaging support means; a material-dispensing hopper mounted on said support means; discharge means beneath said hopper for dispensing asphaltic material therefrom; said discharge means including an orifice for forming the discharging material into a predetermined cross-sectional configuration; channeling means between said hopper and said orifice for conducting material therebetween; heater means surrounding at least a portion of said channeling means to heat material passing therethrough to a formable condition; said heater means comprising a flue structure; and said channeling means including a tunnel structure enclosed within the flue structure and terminating rearwardly in an orifice plate removably attached to and closing the flue structure.

Claim 9

Apparatus for forming a paved channel comprising: a ground-engaging support means; a material-dispensing hopper mounted on said support means; discharge means beneath said hopper for dispensing asphaltic material therefrom; said discharge means including an orifice for forming the discharging material into a predetermined cross-sectional configuration; channeling means between said hopper and said orifice for conducting material therebetween; heater means surrounding at least a portion of said channeling means to heat material passing therethrough to a formable condition; said heater means comprising a flue structure; and said channeling means including a tunnel structure enclosed within the flue structure and terminating rearwardly in an orifice plate removably attached to and closing the flue structure.
