Slip form paving machine with outrigger wheel
First Claim
1. A slip form paving machine, comprising a main frame, front wheel means connected to the frame and mounted for movement about a vertical axis, means for pivoting said front wheel means about said axis to steer the machine, first rear wheel means mounted on the frame, second rear wheel means mounted on the frame and spaced laterally from said first rear wheel means, outrigger wheel means pivoted to the frame about a horizontal axis and spaced on the opposite side of said second rear wheel means from said first rear wheel means, a hopper on the frame to receive a paving material, a slip form carried by the frame and communicating with said hopper for discharging said material onto the ground in a desired configuration, and means for raising said second wheel means out of contact with the ground whereby the machine during paving is supported by said front wheel means, said first rear wheel means and said outrigger wheel means.

Abstract
A slip form paving machine including a main frame supported by a front driven steering wheel and a pair of rear wheels that straddle the fore-and-aft center line of the main frame. An open top hopper is mounted on the frame and the lower end of the hopper communicates with an open bottom slip form, so that paving material, such as concrete fed into the hopper, will flow downwardly and be discharged from the slip form as the machine moves over the terrain. An outrigger frame is pivoted to the main frame about a horizontal axis and is located laterally of the rear wheels. The outrigger frame carries an outrigger wheel which is located laterally outwardly of the slip form and an inclined scraper blade is mounted forwardly of the outrigger wheel. When using a relatively wide slip form, the outrigger wheel is engaged with the terrain, and the rear wheel closest to the outrigger wheel is raised above the terrain so that the machine is supported on the outrigger wheel and the other of the rear wheels.

- 1. A slip form paving machine, comprising a main frame, front wheel means connected to the frame and mounted for movement about a vertical axis, means for pivoting said front wheel means about said axis to steer the machine, first rear wheel means mounted on the frame, second rear wheel means mounted on the frame and spaced laterally from said first rear wheel means, outrigger wheel means pivoted to the frame about a horizontal axis and spaced on the opposite side of said second rear wheel means from said first rear wheel means, a hopper on the frame to receive a paving material, a slip form carried by the frame and communicating with said hopper for discharging said material onto the ground in a desired configuration, and means for raising said second wheel means out of contact with the ground whereby the machine during paving is supported by said front wheel means, said first rear wheel means and said outrigger wheel means.
- 14. A slip form paving machine, comprising a main frame, front wheel means mounted on said main frame, rear wheel means mounted on said main frame, outrigger wheel means pivoted to said main frame about a horizontal axis and spaced laterally from said rear wheel means, hopper means on said main frame for receiving a paving material, a slip form carried by the main frame and communicating with said hopper means, said material flowing from said hopper means and being discharged from said slip form on the ground surface in a desired shape, said outrigger wheel means being located laterally outward of said hopper means and said slip form, said outrigger wheel means comprising an outrigger frame pivoted to said main frame about said horizontal axis and an outrigger wheel journaled on said outrigger frame, and first lifting means for pivoting said outrigger frame about said horizontal axis to raise and lower said outrigger wheel relative to said main frame.
- 20. A slip form paving machine, comprising a supporting structure, front wheel means mounted on said supporting structure for movement about a vertical axis to steer said machine, means for pivoting said front wheel means about said vertical axis, first rear wheel means mounted on the supporting structure, second rear wheel means mounted on the supporting structure and spaced laterally from said first rear wheel means, an outrigger wheel assembly attached to a side of said supporting structure and including an outrigger frame pivoted to the supporting structure about a horizontal axis, said assembly also including an outrigger wheel mounted on said outrigger frame and spaced from said horizontal axis, said outrigger wheel disposed on the opposite side of said second rear wheel means from said first rear wheel means, hopper means mounted on the supporting structure for receiving a paving material, a slip form carried by the supporting structure and communicating with said hopper means, said material flowing from said hopper means and into said slip form and being discharged from said slip form in a desired contour, and means for raising said second wheel means out of contact with the ground surface whereby said machine is supported by said front wheel means, said first rear wheel means and said outrigger wheel, said outrigger wheel being disposed laterally outward of said slip form.
- 25. A slip form paving machine, comprising a supporting structure, wheel means for supporting said structure from the ground, hopper means on said supporting structure to receive a quantity of a paving material, slip form means carried by the supporting structure and communicating with said hopper means for receiving said material from said hopper means and discharging the material on said ground in a desired configuration, outrigger wheel means disposed laterally outward of said slip form means and disposed to support the machine from the ground, and sensing means mounted on said outrigger wheel means and disposed to engage a guide member for maintaining said machine in a given path of travel.
- 27. A slip form paving machine, comprising a supporting structure, wheel means for supporting said structure from the ground, hopper means on said supporting structure to receive a quantity of a paving material, said hopper means comprising a main hopper section and a removable side section, slip form means connect to said side section and communicating with said hopper means for receiving said paving material from said hopper means and discharging said material in a desired configuration on a surface, and outrigger wheel means for supporting said structure from the ground and connected to said side section, said slip form means being located between said wheel means and said outrigger wheel means.
