Definitions

  • This invention relates to the centrifugal lining of iron and steel pipes, tubes and other hollow bodies with a bituminous substance such as natural or artificial asphalt, or other bituminous material or composition (hereinafter referred to as substance7) by spinning the pipes or the like, when charged with the bituminous substance in liquid form so that the substance will be uniformly distributed, by centrifugal action, over the interiors of the pipes or the like.

  • the spinningl f the pipes about their own axes may be e ,ected either by upper travelling members and the lower travelling members to move in opposite directions or by causing them to move in the same direction but at differential speeds which eilects the same action.
  • the appartus preferably comprises a plurality of endless, parallel, power driven roller chains and, thereabove, a. plurality of end less, parallel power driven belts whose lower stretches move 'with a linear velocity different from that of the upper stretches of the roller chains so that when the pipes, after having been charged with the bituminous substance in a liquid condition, are fed on to the chains whereon they lie transversely between adjacent rollers, they are translated bodily, while the belts contacting with them cause them to spin simultaneously about thel are fed one causing the 1927, SerialA No. 201,930, and in Great Britain January 1, 1927.
  • a plurality of lower endless power driven belts may be provided, each arranged around one of .the roller chains so that its upper stretch 4is slack and rests upon the upper stretch of the roller chain which moves under the belt in the same direction but relatively slowly so that, when charged pipes arel fed 1n between the upper and lower belts, the latter sag thereunder between the rollers of.x the chains forming hollows by the progression of which'the ⁇ pipes are translated bodily whileat the saine time being acted on by the differentially vmoving adjacent stretches of the upper and lower belts and are thereby spun.

The burners 52 are adapted to project long fiames into the interior of the pipes on the feed rack, or, if desired, on the convey or bands 19. l
  • the distance between the upper belts and the lower belts 5 is adjusted as before described to suit the diameter of the pipes to be lined.
  • the electric motor 6 is then started and drives the shaft 2, the pulleys 3 and the ⁇ surface 48 on the- 75 lower belts 5 in the direction indicated by the arrow.
  • the motor 39 is started to drive the belts 36 inthe direction indicated by the arrows and at the same linear velocity as the lower belts 5, so that the upper lstretches of the lower belts and the lower stretches of the upper belts are moving in opposite directions at the same speeds.
  • T he motor 10 is started and drives the shaft.
  • the chains 13 move in the same sense as the lower belts 5 but at a very low linear speed in comparison with the speed of said belts, so that there is relative motion between the contacting upper stretches of the belts 5 and of the chains.

  • the result is that vwhile being spun rapidlyby the belts to distribute the lining substance centrifugally and also while being cooled, the pipe is being. carried along by the progression of the hollow in which it rests, at the same speed as the chains.
  • the drive of the upper belts 36 is' arranged so that the lower stretches thereof are slack, giving a greater lap of the belts on the pipes.
  • The' temperature of the pipes when bemg charged with hot bituminous substance should be somewhat greater than the temperature of the lining substance.
  • the lower belts 5 are dispensed with, the pipes resting'directly on the rollers of the roller chains 13 by which they are carried along, the hollewsvbetween the rollers forming .cradles for the pipes in which they are spun by the action of the upper belts 86 which travel at a greater linear speed than the chains 13 and their lower stretches move in the same direction as the upper stretches of the chains.
  • the discharge conveyor has been also dispensed with.
  • pipe lining ap# paratus according to this invention'is susceptible of numerous variations. There may e any practicable number of upper belts and lower belts and chains. For treating pipes of varying diameters, the Stoppers on the various conveyors may be adjustably secured on the endless bands. instead of a number of ramps 21 being provided, one only,'located at one side of the feed conveyor, ma be used so that the pi es on being carrie on to the ramp, are tiited to facilitate charging.
