Description
~S~
-.
One of the more important aspects of laying a good pipeline i.s the obtaining of a strong and durable coupling between the lengths of.pipe, and, where necessary, providing a watertight seal to prevent any leakage therethrough. In addi~ion, such a coupling should be as economical as possible, both in construction and in time of installation~ The devices currently used for joining two lengths of pipe are called band or split band couplers and generally consist of large band or semicircular band sections (split bands) which are wrapped about the juncture of the adjacent pipe lengths, overlapping a portion of each pipe, and a pair of somewhat large brackets, one being secured to each end of the band or bands. Each bracket has one or more apertures therein for receiving bolt means which extend through the apertures and across the open ends of the band. Upon tightening, the bolt means draws the ends of the band togethèr thereby coupling khe pipe lengths. .:

' While these couplers have been widely used for years on corrugated pipe, applicant has recently developed a channeled band coupler which has several advantages over the conventional band or split coupler. The channeled band coupler has a walled channel therein which fits about radial end flanges formed at the ends of the pipe lengths. The use of a channeled band coupler disposed about the abutting or adjacent flanges not only provides a stronger coupling in that it does not rely solely on radial pressure for its holding force, but is also ~-considerably easier to use in the field and therefore more econ-omical.
In joining lengths of pipe, the pipes must be properly aligned prior to coupling to prevent any leakage through the band. Split band couplers are of little assistance in obtaining a proper alignment. Pipe alignment is greatly facilitated by the channeled band coupler with its use of radial end flanges to secure the pipe length as such flanges are self aligning within the channeled couplers. It is also difficult to obtain a watertight seal using the conventional band couplers as the necessary gaskets are quite difficult to hold in place about the juncture of the pipe lengths. This problem is also alle- `
viated by the use of the channeled band coupler as the walled channel is an ideal means for securing a gasket about the abut-ting pipe ends.
As indicated, the use of the channeled band coupler requires that the pipe lengths be provided with radial end flanges prior to coupling. Accordingly, it may often be nec-essary to maintain different types of coupling devices for use with flanged or non-flanged pipe. r~hile channeled band coup-lers can only be used if the pipe lengths are provided with radial end flanges, band couplers can be used to secure lengths -of flanged pipe, however, the strength of such a coupling is reduced due to the loss of surface area contact between the ','', ~ ~ ; ': , bands and pipe lengths caused by the formation of the radial end flange.
Not only are the ends of the pipe lengths from which the flanges are formed removed from mating contact with the band coupler but the area on the pipe lengths adjacent the flanges are generally flattened out during the flange forming process for about one to two inches into a non-corrugated suface oE generally constant radius which is also removed from contact with the band. The result is a loss of coupling strength when a band coupler is used to secure lengths of flanged pipe. It would be highly desirable to have a single coupling device which retained the benefits of the channel band coupler when used with flanged pipe but which would also provide a strong and durable coupling when used in securing non-flanged pipe.
According to one aspect of the present invention there is pro-vided a pipe coupler for connecting adjacent flanged corrugated pipe lengths and for connecting adjacent unflanged corrugated pipe lengths, said coupler comprising a central portion having a walled channel therein, a pair of lateral wing portions disposed on either side of said central portion and having corrugations therein for mating with the corrugations in said pipe length, a pair of non-corrugated spacer sections extending between said central portion and said lateral wing portions and spacing said central portion from said corrugations in said lateral wing portions such that upon securing said coupler about the ends of axially aligned adjacent pipe sections, said coupler is in continual mating contact with said pipe lengths from the extended ends of said lateral wing portions to said channel, said channel is disposed over the end of said pipe lengths and upon said pipe leng~hs being subjected to a disjunctive force and provided with radial end flanges, said flanges abut the walls of said channel to maintain said pipe lengths in adjacent axial align-ment, and means for securing said coupler about said adjacent pipe lengths.

lengths and for connecting adjacent unflanged corrugated pipe lengths, said coupler comprising a pair of coupling members, each of said members having a central portion and a pair of lateral wing portions, said central portion having a flange receiving channel therein defined by a pair of retaining walls and a spanning member extending therebetween, said lateral wing portions being disposed on either side of said central portions and having corrugations therein for mating with the corrugations in said pipe lengths, said central portion being laterally disposed from s id corrugations in said wing portions such that upon said coupling members being secured about the ends of axially aligned adjacent pipe lengths, said members are in continual mating contact with said pipe lengths from the extended ends of said members to said retaining walls and upon said pipe lengths being subjected to a disjunctive force and provided with radial end flanges, said walls abut said flanges to maintain said pipe lengths in adjacent axial alignment, and means for securing said coup- ~
ler about said adjacent pipe lengths. .
According to a further aspect of the invention there is pro-vided a pipe coupler for connecting adjacent flanged corrugated pipe lengths and for connecting adjacent unflanged corrugated pipe lengths, ;~
said coupler comprising a pair of coupling members, each of said members : :
having a central portion, a pair of lateral wing portions, and a pair ~ :~

said walls abut said flanges to maintain said pipe lengths in adjacent axial alignment, and means for securing said coupler about said adjacent pipe sections.
A gasket can be disposed within the channel of the coupler to provide a strong waterproof seal when desired.

Figure 2 is a sectional view of the pipe coupler disposed about flanged pipe sections.
Figure 3 is a sectional view of the pipe coupler disposed about abutting non-flanged pipe sections and including a gasket therein.
Figure 4 is a side sectional view of the pipe coupler.
The coupling device 10 is seen to be comprised of a pair of semicircular sections 12 and 14 which are adapted to be disposed about `
the ends of a pair of abutting lengths of corrugated pipe 16 to securely ;
couple the pipe lengths together, as shown in the drawings. While the coupling device could be of a single piece construction for use with smaller diameter pipes, in the preferred embodiment two sections are employed. Each section includes a central portion 18 and a pair of cor-rugated lateral wing portions 20 and 22 on either side thereof. The central portion 18 has a channel 24 therein which is defined by walls 26 and a spanning member 27 extending therebetween. Each lateral portion includes a lateral spacer or extension 28 which is non-corrugated and of a constant radius, integrally joins the wing portions of each section with the central channeled section and displaces the central channeled portion from the valleys 30 of the adjacent corrugations 32 in the lateral portions 20 and 22.
If the ends of the pipe lengths 16 are provided with radlal end flanges 34, as shown in Figure 2, the flanges of the adjacent pipe lengths are placed in abutting or adjacent relationship and the sections 12 and 14 of the coupler are dis-posed thereover with the central channels 24 of the sections being positioned about the flanges 34. An angle brace 36 is welded or otherwise affixed to each end of the coupler section which includes one or more apertures 38 therein for receiving bolt means 40. Upon disposing the coupler sections about the abutting end of the pipe lengths as described, the bolt means are tightened, drawing the ends of the sections together and thereby tightening the coupling device 10 about the abutting pipe length. ~--When the coupling device is secured about lengths of flanged corrugated pipe, the corrugations 32 in the lateral portions 20 and 22 of the coupler sections mate with and bear against the corrugations 42 in the pipe lengths; the lateral extensions 28 of the coupler bear against the flat, cylindrical surfaces 44 on the pipe lengths adjacent the radial end flanges and the base of the channel walls 26 bear against the base of : .
the radial end flanges 34 to provlde a strong and durable coupling. In this regard it should be noted that due to the development of more economical methods of construction, cor-rugated pipe is generally helically or spirally wound as op-posed to annularly. Consequently, the ends of the pipe lengths must be recorrugated to provide annular corrugations therein prior to the use of a band coupler having annular corrugations.
This recorrugating process imparts this non-corrugated flat or constant radius area 44 to the pipe lengths adjacent the radial end flanges. The lateral extensions 28 of the coupler sections which are disposed between the central portions 18 and the cor-rugated wing portions 32 not only displace the central channeled ~-portion from the valleys 30 of the adjacent corrugations in the '' ' ' c ?ler to accommodate the radial end flanges of the plpe lengths and provide a gasket holding means as will be described, but provide continual contact between the coupler and pipe lengths from the mating corrugations to the bases of the radial end flanges thereby increasing the strength of the coupling.
If a pipeline were constructed as above described incorporating flanged pipe and the coupling device 10 were sub-jected to tensile forces sufficient to cause the mating corruga-tions to slide laterally with respect to one another, the linear separation of the separate pipe lengths would be prevented by the radial end flanges bearing against the walls 26 of the central portion of the coupling. If such a pipeline were sub-jected to a substantial loading force which would tend to cause misalignment of the pipe sections, the ~langes on one side of the pipe would be forced together whlle the flanges on the ;~
other side of the pipe, downstream of the loading force, would -tend to separate and bear against the interior walls of the ;~
central channel and thereby prevent further separation and disjunction of the pipeline. In this manner the coupling device 10 utilizes the radial end flanges of the pipe lengths to pre-vent separation or misalignment of the individual pipe lengths or sections comprising the pipeline when subject to disjunctive forces.
In those instances, as shown in Figure 3, wherein the pipe lengths are not provided with radial end flanges, the central portion 18 of the coupling device is disposed over the abutting ends 46 and 48 of the pipe lengths and the two lengths are held together under the force of the corrugated lateral wing portions 20 and 22 pressing against the adjacent corrugated pipe lengths. The lateral extensions 28 of the coupler are also in gripping contact with the reformed end portions 44 of the non-flanged pipe to provide continual gripping contact with the pipe lengths up to the channel walls 26 of the coupler.

In those instances where a watertight seal is desired, a gasket 50, which is constructed of neoprene or a suitable rubber-like material, is positioned within the channel 28 and over the abutting ends 46 and 48 of the pipe. In such an in-stallation, the channel walls 26 act to hold the gasket firmly in place and thereby provide an excellent watertight seal. It is of course understood, that a gasket can be similarly employed when the coupling device 10 is used to secure flanged lengths of pipe whereupon the gasket is disposed between the walls of the channel over the ends of the radial flanges. While a flat gasket 50 is illustrated in the drawings, the gasket when used with flanged pipe also could be of a T configuration and extend between the radial end flanges of the adjacent pipe sections as well as thereover.
Various changes and modifications may be made in carrying out the present invention without departing from the spirit and scope thereof. Insofar as these changes and modifica-tions are within the purview of the appended claims, they are to be considered as part of the invention.
