Rail drive duct connection system
View Patent ↗An apparatus for joining high pressure ducts has a first and second bar secured to adjacent to be joined ducts. A coupling mechanism having a U-shape is frictionally engaged onto the first and second bar. An end of the coupling mechanism frictionally engages the surface of the bar members so that the coupling mechanism is slidably removably connected to the first and second bars.
1. An apparatus for joining high pressure ducts by welding the apparatus to a pair of ducts comprising:
a first bar welded to a first duct, said first bar including a first member having a surface for welding with the first duct, a second member extending from said first member, said second member having a surface for engaging with a coupling mechanism;
a second bar welded with a second duct, said second bar including a first member having a surface for welding with the second duct, a second member extending from said first member, said second member having a surface for engaging with the coupling mechanism; and
the coupling mechanism having an overall U-shape with legs, said legs opposing one another and including upturned ends for engaging said surface of said second members of said first and second bars, said upturned ends being substantially parallel to the legs and frictionally engaging said surfaces of said second members so that said coupling mechanism is removably connected with said first and second bars such that the coupling mechanism can only be slid onto or off of the first and second bars to couple the first and second bars together.
2. The apparatus of claim 1 , further comprising a sealing gasket to be positioned between said first and second bars.
3. The apparatus of claim 1 , wherein a plurality of first and second bar and coupling mechanisms correspond to a number of sides of the first and second duct.
4. The apparatus of claim 3 , further comprising a plurality of corner connectors, each connector prohibiting overextending of adjacent first and second bars.
5. The apparatus of claim 1 , wherein a second coupling mechanism is coupled with said first coupling mechanism in an inverted position.
6. The apparatus of claim 1 , further comprising the first duct and the second duct weldably connected with the first and second bar members.
7. An apparatus for joining high pressure ducts by welding the apparatus to a pair of ducts comprising:
a plurality of first bar members, said plurality corresponding to a number of sides of the to be joined ducts, each first bar member including a first member having a surface welded to a first duct, a second member extending from said first member, said second member having a surface for engaging with a coupling mechanism;
a plurality of second bar members, said plurality corresponding to the number of first bar members, each second bar member including a first member having a surface welded to a second duct, a second member extending from said first member, said second member having a surface for engaging with the coupling mechanism;
a plurality of coupling mechanisms, each coupling mechanism having an overall U-shape with legs opposing one another and including upturned ends for engaging said surface of the second members of said first and second bar members, said upturned ends being substantially parallel to the legs and frictionally engaging said surfaces of said second members so that said coupling mechanisms are removably connected with said first and second bars, the coupling mechanisms are only slidable onto and off of the first and second bars to couple the first and second bars together; and
a plurality of end connectors, each end connector prohibiting overextending of adjacent ends of said first bar members and second bar members for providing a substantially continuous apparatus about the to be joined first and second ducts.
8. The apparatus of claim 7 , further comprising a seal positioned between said plurality of adjacent first and second bar members.
9. The apparatus of claim 7 , wherein each coupling mechanism includes a second coupling mechanism coupled with said first coupling mechanism in an inverted position.
10. The apparatus of claim 9 , wherein said plurality of end connectors are coupled with said second coupling mechanisms.
11. The apparatus of claim 10 , wherein each end connector includes a housing, a fixed leg and a movable leg.
12. The apparatus of claim 7 , wherein said coupling mechanism is a bar member.
13. The apparatus of claim 7 , further comprising the first duct and the second duct weldably connected with the first and second bar members.
