Abstract

A paving surface roller having indentation rumble strips comprising main pipe segments is mounted for support and operation on a frame structure of a paving machine or other vehicle and the drum is movable from operable to inoperable position above the surface by means of hydraulic rams attached to swinging arms on the frame. In one version the drum is supported and moved. In other versions for use with fixed drums, ground engaging wheels are selectively moved into place to elevate or lower the drum.

Claims

1. In a paving vehicle for selectively making indentations on a surface:

paving means on said vehicle for supporting same during paving movement over the surface,

a roller drum on said vehicle comprising means for making indentations when engaged against the surface such as asphalt and the like,

means on said vehicle selectively for raising and lowering said roller drum relative to the surface,

and means for supporting said vehicle for movement over the surface when said drum is in raised position.

2. The device in claim 1 including a support frame mounted on the end of said vehicle for removal therefrom, said support frame comprising vertical frame members,

a respective support arm movably mounted at opposite sides of said frame on opposite sides of said vehicle and means on said support arms for rotatably supporting a respective end of said drum thereon,

and power means on said frame for raising and lowering said drum.

3. The device claimed in claim 2 wherein said arms being provided with a guide member for guiding a respective arm on said frame when raising or lowering said drum.

4. The device claimed in claim 2 wherein there are at least two hydraulic cylinders attached on opposite sides of said frame adjacent opposite ends of said roller drum.

5. The device claimed in claim 3 wherein each of said arms has a journal thereon rotatably supporting a respective member on the respective end of the drum.

6. The device claimed in claim 2 wherein said support frame structure comprises vertical frame members, horizontal frame members and diagonal frame members and there being plates on each side of said frame attached to said vertical frame members.

7. The device claimed in claim 3 wherein there is a slot in each end of the frame and said guide member travels in said slot when said arm is raised or lowered.

8. The device in claim 1 wherein said means for supporting said vehicle comprises a frame support, wheels on said frame support engageable with the surface when said drum is elevated and power means on said vehicle for moving said frame support.

9. The vehicle in claim 3 wherein said roller drum is fixed for rotation on the front of said vehicle and said support frame is mounted in front of said drum on the front of said vehicle.

10. The vehicle in claim 8 wherein said roller drum is mounted for rotation on the rear of said vehicle for steering said vehicle, and said frame support is mounted at the rear of said drum.

11. In a vehicle:

an impression roller drum of one end of said vehicle and a ground support means on the other end thereof,

means on said vehicle for selectively raising and lowering said drum with respect to the ground surface so as to engage and disengage the operation of said drum on said surface, said means comprising a power frame on said vehicle and power means on said frame,

there being means for selectively supporting said vehicle comprising the power frame and wheels on said frame selectively engageable with the surface when said drum is elevated by said power means on said moving said frame.

14. The vehicle in claim 11 wherein the power means comprises at least two hydraulic piston and cylinder units operable between the vehicle and the wheels to raise and lower same.

15. The vehicle in claim 14 wherein said wheels are supported on a transverse axle therebetween, arms on opposite sides of said frame support connected to said axle, said hydraulic units being attached to said arms adjacent opposite ends thereof.

12. In a vehicle:

an impression roller drum on one end of said vehicle and a ground support means on the other end thereof,

means on said vehicle for selectively raising and lowering said drum with respect to the ground surface so as to engage and disengage the operation of said drum on said surface, said means comprising a power frame on said vehicle and power means on said frame,

said drum being fixed for rotation on the front of said vehicle and said frame being mounted in front of said drum on the front of said vehicle.

13. In a vehicle:

an impression roller drum on one end of said vehicle and a ground support means on the other end thereof,

means on said vehicle for selectively raising and lowering said drum with respect to the ground surface so as to engage and disengage the operation of said drum on said surface, said means comprising a power frame on said vehicle and power means on said frame,

said drum being mounted for rotation in the rear of said vehicle for steering said vehicle, and said frame support being mounted at the rear of said drum.

16. In a vehicle:

an impression roller drum on one end of said vehicle and a ground support means on the other end thereof,

means on said vehicle for selectively raising and lowering said drum with respect to the ground surface so as to engage and disengage the operation of said drum on said surface, said means comprising a power frame on said vehicle and power means on said frame,

said drum having a wheel on each end thereof and each wheel having a pneumatic tire which is selectively inflatable or deflatable whereby said drum may be removed from said vehicle and rolled on said tires or said tires may be deflated when said drum is in use on said vehicle.

17. The vehicle in claim 16 wherein each of said wheels is removable from the end of said drum whereby said drum may be supported on said vehicle without the wheels thereon.

18. In a vehicle:

an impression roller drum on one end of said vehicle and a ground support means on the other end thereof,

means on said vehicle for selectively raising and lowering said drum with respect to the ground surface so as to engage and disengage the operation of said drum on said surface, said means comprising a power frame on said vehicle and power means on said frame,

a support frame mounted on the end of said vehicle for removal therefrom, said support frame comprising vertical frame members,

a respective support arm movably mounted at opposite sides of said frame on opposite sides of said vehicle, means on said support arms for rotatably supporting a respective end of said drum thereon,

power means on said frame for raising and lowering said drum,

said support frame structure comprising vertical frame members, horizontal frame members and diagonal frame members and there being side plates on each side of said frame attached to said vertical frame members.

19. In a vehicle:

an impression roller drum on one end of said vehicle and a ground support means on the other end thereof,

means on said vehicle for selectively raising and lowering said drum with respect to the ground surface so as to engage and disengage the operation of said drum on said surface, said means comprising a power frame on said vehicle and power means on said frame,

said power frame being mounted on the end of said vehicle for removal therefrom, said power frame comprising vertical frame members, a respective support arm movably mounted at opposite sides on said frame on opposite sides of said vehicle and means on said support arms for rotatably supporting a respective end of said drum thereon, and said power means on said frame selectively raising and lowering said drum.
