Abstract

A paver machine for applying paving material to narrow paths is disclosed. The machine includes a storage hopper and frame elevated above a roadbed by at least three wheeled unit members. A free-floating screed assembly located beneath the hopper and pivotally attached to the frame applies a paving material matte to the roadbed as the paver machine is moved along by a front end loader or the like.

6. A paving machine according to claim 1 wherein, said at least one third wheeled unit member comprises a dual wheel assembly on a wheel support strut member, said third wheeled unit member positioned in the center of said frame member.

7. A paving machine according to claim 6 wherein, said at least one third wheeled unit member is pivotally connected to said wheel support strut member opposite said storage hopper open bottom end.

8. A paving machine according to claim 1 wherein, said feed hopper means comprises a rectangular feed hopper member with an open top end and a smaller open bottom end, said feed hopper member having front and rear panels and two side panels, each side panel fastened to one connecting arm member.

9. A paving machine according to claim 8 wherein, said adjustable screed plate member is a planar member pivotally secured at one edge to said feed hopper member rear panel at a bottom edge thereof.

10. A paving machine according to claim 9 wherein, said adjusting means comprises threaded turn buckles positioned between said screed plate member and said connecting arm members.

11. A paving machine according to claim 1 wherein, said adjustable screed plate member comprises a hollow member of triangular cross section, said hollow triangular member having a flat bottom side, a vertical front side and an angled top side, said hollow triangular member pivotally secured between said pair of connecting arm members.

12. A paving machine according to claim 11 wherein, said feed hopper means comprises a bottom extended portion of said front panel of said storage hopper member, said vertical front side of said hollow triangular screed plate member, and two side panel members, each panel member reversibly fastened to said screed plate member vertical front side and to a connecting arm member.

13. A paving machine according to claim 1 further comprising, means for adjusting the position of said side panel members relative to said bottom end of said storage hopper member.

14. A paving machine according to claim 1 further comprising, means for elevating said screed assembly relative to the roadbed for transportation of said paving machine.

15. A paving machine according to claim 1 further comprising, means for heating said screed plate member.

16. A paving machine according to claim 15 wherein, said heating means comprises at least one burner head mounted adjacent said screed plate member, with combustible fuel supply means providing fuel to said burner head.

17. A gravity feed free-floating screed paving machine for applying paving material to a roadbed comprising;

(a) a hollow storage hopper member with an open top end and a smaller open bottom end, said hopper member having front and rear panels and two side panels, all panels tapering in width from said hopper member top end to said hopper member bottom end;

(b) first and second wheeled unit members, each wheeled unit member attached to one hopper side panel near said smaller bottom end thereof, whereby said hopper member is elevated a selected distance above said road bed;

(c) a frame member supporting said storage hopper member and wheeled unit members attached thereto, said frame member extending beyond said tapered hopper member front panel, said frame member elevated a selected distance above the roadbed by a third wheeled member unit comprising a pair of wheel members, each wheel member rotatably attached to an axle fastened to said frame member;

(d) a free-floating screed assembly positioned below said elevated storage hopper and elevated frame member and between said first and second wheeled unit members and pivotally connected to said frame member, said screed assembly comprising;

(i) a generally rectangular feed hopper member with an open top end and smaller open bottom end, said feed hopper member having front and rear panels and two side panels, said feed hopper member positioned with open top end in register with said storage hopper open bottom end;
