- a suitable material transporting line 62 extends from a coupling 60 which is connected to a suitable source of vacuum (not shown) to obtain the transporting of material as hereafter described.
- the cover is removed from the nozzle 4 and the adaptor 2 slipped over the outer end of the nozzle 4 with the free end of the nozzle abutting or substantially abutting the shoulder at the bottom of the bore 10.
- Adaptor 2 is then secured to nozzle 4 by tightening the set screw 12.
- the free end of the outer tube 18 is then aligned with the bore 16 and is slidably inserted therethrough through bore 16, and through nozzle 4 into the material (not shown) in the hopper to a desired length of penetration with the outer end of the outer tube 18 being located outwardly of the adaptor 2.
- the outer tube 18 When the outer tube 18 is properly located it is secured in position relative to the nozzle 4 and the hopper by tightening of the set screw 20.
- the portion of the bore 16 which receives the vent tube 24 is located at the upper portion of the bore 16 to locate the tube 24 such that the lower edges of openings 28 are spaced the same distance above the lowermost edge of the body 22.
- a filter assembly 32 is then inserted over the free end thereof with the opening in the free edge 52 of boss 46 encompassing the outer end of the vent tube 24.
- the inner end of the inner tube 36 is initially located close to the end cap 23, and the coupling 60 with line 62 attached and a suitable vacuum (usually a steady vacuum of between 8 and 20 inches of mercury) applied.
- a suitable vacuum usually a steady vacuum of between 8 and 20 inches of mercury
- air will flow from outside the hopper through the filter 40 into the pocket 38 through passageway 48 into the outer open end of the vent tube 24, along the vent tube 24, through the slot 30, into the interior of the outer tube 18, then through th interior of the inner tube 36 and through the line 62.
- the tube 36 is moved axially outwardly of the outer tube 18 and as its inner end passes outwardly between the openings 28 material within the hopper will be drawn by the air stream fiow into the inner tube 36 and entrained therein and flow through the lin 62 to a location as desired.
- the axial length of openings 28 between the inner end of the inner tube 36 and the end of each opening 28 adjacent the end cap 23 define material entrance areas. As such material entrance areas increase th material flow from the hopper increases; however, as the inner tube 36 is moved towards maximum material entrance areas, surging in the material flow will occur. The area of the entrance areas at which such surging occurs will vary dependent upon the characteristics and condition of the material being conveyed; however, such surging is quickly noticeable during such transporting.
- the inner tube 36 is slipped inwardly of the outer tube 18 until the surging stops and a steady material flow occurs. With the inner tube 36 and outer tube 18 located to obtain steady flow in such manner the inner tube 36 is anchored with respect to the outer tube 18 y Set SCffiW 1' Th; indices 51 are provided to permit duplication of the setting of the inner tube 36 when desired.
- the inner tube 36, outer tube 18, the housing for the filter assembly 32 and the adaptor 2 can be made from any suitable material, such as aluminum tubing and aluminum casting, which is easily positioned and will stand up in service. Further air tight joints can easily be provided with such structure by welding or brazing. Also various portions which engage each other may be provided with suitable gasket means to obtain better air seals.
- the set screws 12, 20 and 41 comprise releasable fasteners and can be of any accessible fastening means as desired.
- vent line 24 is fabricated from aluminum tubing and the filter assembly 32 is an aluminum casting, the filter assembly 32 is welded to the outer tube 18 to provide an air tight joint between the outer end of the outer tube 18 within the bore 34. Desirably the outer end of the vent line 24 is welded to the edge 52 to provide an airtight joint.
- the transporting device as described is particularly desired for railway car hoppers since it can be installed with either nozzle 4 at either side of a hopper car.
- the outer tube 18 is of a length so that it will extend through the entire distance needed to discharge the known hopper car structures.
- the outer tube is adjustably positioned relative to the nozzle 4 to which the adaptor 2 is secured so that the openings 28 are located below a discharge area of a hopper.
- the outer 18 is adjustably positioned, in turn, with each of such discharge openings.
- the filter assembly 32 is located at variable distance from the adaptor 2 during use, or can abut the adaptor 2, if desired.
- the opening 28 can be axially overlapping and of different axial length if desired rather than laterally aligned uniform length openings. Further, if desired, axially spaced pairs of openings 28 can be used.
- the device of this invention can also be modified by replacing the end cap 23 and the vent line 24 with a filtered air entry at the end of the outer tube 18 at which the end cap 23 is show-n.
- a filtered air entry at the end of the outer tube 18 is essential that such end of the outer tube 18 be open to the atmosphere.
