摘要： The specification discloses fittings for attachment of boot plates or otherwise closing the end of pipe piling and for coupling vertically superimposed sections of pipe piling, which fittings are readily and quickly installed and which provide a seal with the pipe to prevent water from entering the interior of the piling, as by seepage, while the piling is in the ground prior to being filled with concrete. One type of fitting is in the form of a shallow pan, on the bottom of which is a boot plate, and the walls of which have a portion smaller in diameter than the outer diameter of the pipe piling so as to expand thereover and provide a metal-to-metal seal with the piling. Variations of this type are disclosed wherein the bottom of the pan is a disc of heavy gauge metal welded to a circular tapered sleeve of relatively thin gauge. Another type of fitting is in the form of a sleeve having an annular groove formed internally midway of its ends in which is disposed a drive ring of relatively heavy metal having O-ring seals on opposite sides thereof. The pipe piling expands the opposite ends of the coupling in moving inwardly into contact with the drive ring and is sealed by engagement with the O-ring seals. A variation of the latter type of fitting is adapted to couple pipe piling of different diameters.

摘要： The specification discloses a sleeve type coupling for providing a limited flexible connection between two sections of pipe, particularly large diameter pipe such as shore dredge pipe. The coupling has an overall length in the range of one and a half to two times the diameter of the pipe sections to be coupled and is of uniform wall thickness tapering uniformly from end to end except for a relatively short section intervening between the opposite end sections. The end sections are tapered in the range of 3 1/2 * to 5* with respect to the longitudinal axis and the section intervening between the end sections is of a length approximately 0.15 to 0.20 times the diameter of the pipe sections to be coupled, and is tapered at an angle to the longitudinal axis substantially larger than that of the end sections. Another embodiment of sleeve coupling comprises an inwardly tapered downstream end section, a generally cylindrical upstream end portion closely surrounding the upstream pipe section and an intervening tapered section of relatively steep slope on which the end of the upstream pipe section abuts. The cylindrical end portion is adapted to be sealed by an annular seal to the upstream pipe section. Another embodiment of sleeve coupling is similar to the previously described one except that a wear sleeve is secured inside the coupling sleeve at the intervening tapered section for resisting wear due to effluent abrasion on the coupling itself.

摘要翻译： 本说明书公开了一种套管型联接器，用于在管道的两个部分之间提供有限的柔性连接，特别是大直径的管道，例如岸上疏通管道。 联接器的总长度在待连接的管部分的直径的一倍半到两倍的范围内，并且具有均匀的壁厚度从端到端均匀地逐渐变细，除了介于相对端部之间的相对短的部分 。 端部相对于纵向轴线在31/2度至5度的范围内逐渐变细，并且插入在端部之间的部分的长度为要联接的管道部分的直径的约0.15至0.20倍，以及 与纵向轴线成一定角度地基本上大于端部部分的锥度。 套筒联接件的另一实施例包括向内锥形的下游端部分，大致圆柱形的上游端部分，其紧密地围绕上游管部分以及相对陡峭的斜面的中间锥形部分，上游管部分的端部邻接于该中间锥形部分。 圆筒形端部适于通过环形密封件密封到上游管段。 套筒联接器的另一个实施例类似于前面描述的，不同之处在于，在中间锥形部分处，将耐磨套筒固定在联接套筒内部，以抵抗由于联接器本身上的流出物磨损而引起的磨损。

摘要： The specification discloses a number of pipe coupling devices for sealingly connecting the adjacent ends of two coaxially disposed pipe sections. All of the devices utilize a common principle for effecting compression of a gasket ring seal, namely the transfer of the turns of a spiral or helical band of relatively thin gauge metal from one side to the other of a cylindrical or disc-like radial wall in a housing, through a slotted opening in the housing wall or between two successive roller bearings carried on the housing, by relative rotation of the housing and the spiral or helical band coaxially with respect to the pipes to be joined. All embodiments have a pair of ring seals, one for each pipe section, the ring seals being integrally joined or separate. In certain embodiments, the ring seals are simultaneously or separately compressed by rotation of the housing with respect to the spiral or helical band. In other embodiments the helical band is bonded at opposite ends to a circular sleeve coaxial to the pipe and intervening between the pipe and the housing. In these embodiments, compression of the gasket ring seals may be effected by rotation of the circular sleeves relative to the housing or vice versa.
