Abstract

A three-wheeled machine carries a hopper positioned to receive paving material from a dump truck immediately in front of the machine, the hopper being emptied by a conveyor oriented transversely to the path of the machine. A left front wheel, a left rear wheel and a right side wheel support the machine and are so connected to the machine and to actuating mechanisms as to lift or lower the left and right sides of the machine in a selective manner, and thereby enable the machine to be elevated or lowered in level fashion, or to be inclined either toward the left or toward the right. The left rear wheel and the right wheel are independently driven and thus afford "skid steer" capability. Of particular interest is the construction and operation of the left rear wheel which selectively enables it to be moved not only up and down but also in a fore and aft direction between a retracted position, for compactness while the machine is being transported, and a projected position, for maximum stability of the machine while being operated.

Claims

1. Machine for transferring paving material comprising:

a. a frame having a front end, a rear end, a left side and a right side,

said frame including a fore and aft rail extending between said front end and said rear end;

b. a hopper mounted on said frame for the reception and temporary storage of paving material;

c. at least three wheels;

d. means for mounting each of said wheels on said frame wherein there is movement of said wheels between a first lower position relative to said frame and a second upper position relative to said frame;

e. means for mounting at least one of said wheels on said rear end of said frame wherein there is movement between a forwardly retracted position relative to said rear end of said frame and a rearwardly projected position relative to said rear end of said frame,

said means for mounting said one of said wheels including a sleeve translatable on said rail for fore and aft movement, a fore and aft plate, means for mounting said plate on said sleeve wherein there is rotation of said plate about a transverse axis, means on said plate for rotatably mounting said one of said wheels, a first hydraulic ram mounted on said frame and connected to said sleeve, said first hydraulic ram being adapted to translate said sleeve, said plate, said wheel mounting means and said one of said wheels in a fore and aft direction, and a second hydraulic ram mounted on said sleeve and connected to said plate, said second hydraulic ram being adapted to elevate and lower said plate, said wheel mounting means and said one of said wheels; and

,

f. control means on said frame for selectively moving each of said wheels between said first lower position and said second upper position and for moving said one of said wheels between said forwardly retracted position and said rearwardly projected position.

2. A machine as in claim 1 in which each of said wheel mounting means includes a bracket supported by said frame, a bar pivotally mounted on said bracket for rotation about a transverse axis, lever means on each of said bars for rotatably mounting the respective one of said wheels;

and in which said means for moving said wheels between said first position and said second position includes hydraulic rams pivotally mounted on said frame and pivotally connected to said lever means for urging said wheels downwardly and upwardly about the respective transverse axes in response to actuation of said control means.

3. A machine as in claim 2 in which said means for mounting at least one of said wheels on said rear end of said frame includes a sleeve translatably mounted on said frame for fore and aft movement, means for mounting said bracket on said sleeve, and a hydraulic ram pivotally mounted at one end on said frame and at the other end on said sleeve, said ram being oriented in a fore and aft direction so that said sleeve, said bracket and said one of said wheels are moved in a fore and aft direction when said ram is selectively actuated by said control means.

4. Machine for transferring paving material comprising:

a. a frame having a front end, a rear end, a left side and a right side;

b. a left front wheel;

c. means for mounting said left front wheel on said frame adjacent the left front portion of said frame wherein there is movement between a lower position and an upper position;

d. a right wheel;

e. means for mounting said right wheel on the right side of said frame wherein there is movement between a lower position and an upper position;

f. a left rear wheel;

g. means for mounting said left rear wheel on said frame adjacent the left rear portion of said frame wherein there is movement of said left rear wheel between a lower position and an upper position and between a forward retracted position and a rearward projected position;

h. first control means connected to said frame and to each of said wheels for selectively moving each of said wheels between said lower position and said upper position; and

,

i. second control means connected to said frame and to said left rear wheel for selectively moving said left rear wheel between said forward retracted position and said rearward projected position.
