Abstract

Apparatus for continuously applying a viscous mass to an object comprises a rigid tube and a flexible housing mounted axially within the tube and spaced radially from the wall thereof. The hose is provided with conveyor means for pneumatically feeding dry material to it. The hose is radially distendable into the annular space about it under action of the flowing material to mix the material and enhance its movement.

Claims

1. Apparatus for continuously mixing and applying a viscous mass to an object, comprising a rigid tube, a flexible hose located co-axially within said tube, said flexible hose being secured to said tube at its rear end and extending substantially freely along the length of said tube radially spaced from the inner wall thereof, means for pneumatically feeding particulate material axially to the rear end of said flexible hose, said flexible hose being swingable and radially distendable under the flow of said material toward its forward end.

2. The apparatus according to claim 1 including means for delivering liquid radially through said pipe and said flexible hose to mix with said dry material.

3. The apparatus according to claim 2 wherein the means for delivering the liquid is arranged perpendicularly to the flow of material.

4. The apparatus according to claim 1 wherein said flexible hose is provided with at least one radially inwardly directed circumferential ring providing an enlarged annular space between said hose and the inner wall of the rigid tube.

5. The apparatus according to claim 1 including a braking element located at the forward end of said flexible hose, said braking element providing a translatory change in velocity to the mass.

6. The apparatus according to claim 5 wherein said braking element comprises a rebound nozzle.

7. The apparatus according to claim 6 wherein said rebound nozzle is provided with an adjustable baffle.

8. The arrangement according to claim 7 wherein said baffle member comprises a disk.

9. The arrangement according to claim 7 wherein the baffle member comprises a concave dish.

10. The arrangement according to claim 7 wherein the baffle member comprises a conical body.

11. The apparatus according to claim 5 wherein the braking element comprises a spin chamber in which the mass is given a rotary component of movement.

12. The apparatus according to claim 11 wherein the spin chamber is provided with a replaceable baffle insert arranged at the exit mouth thereof to lead the mass to the peripheral edge thereof.

13. The apparatus according to claim 11, wherein said chamber is provided with a neck of reduced diameter and a flexible hose secured thereto.

14. The apparatus according to claim 1 wherein the forward end of the flexible hose is radially free of said rigid tube.

15. The apparatus according to claim 1 including a coupling member secured at the rear end of said tube for connection to a supply line, and a sleeve secured in said coupling, said flexible hose being arranged within said sleeve and supported thereby.

16. The apparatus according to claim 1 including a flow directing cap arranged at the forward end of said flexible hose, said cap having an angular flow channel, and a conical impact insert arranged axially of the flow of said material.

17. The arrangement according to claim 16 wherein said insert is made of hardened metal.

18. The apparatus according to claim 1 wherein said flexible hose is of uniform cross section throughout its length.
