Description
llZ~;~(18 One of the more important aspects of laying a pipe line is the ob-taining of a good seaL between adjacent lengths of pipe. The apparatus used must often provide a water tight seal between each of the joined pipe lengths to prevent any leakage therethrough and must be strong and durable to with-stand high pressures over an extended period of time. Ands of course, it must be economical, both in construction and in time of installation. The devices currently used for joining two adjacent pipe lengths generally consist of a large band which is wrapped about the juncture of the adjacent pipes, over-lapping a portion of each pipe and a pair of somewhat large brackets, one be-ing secured to each end of the band. Each bracket has a plurality of aper-tures therein and; they are connected by bolt means which extend through theapertures and across the openedends of the band. Upon tightening, the bolt means draw the ends of the band together, thus joining the pipe lengths. Due to the size of the bands required, such devices are generally somewhat expen-sive, quite bulky and hence somewhat cumbersome to install. In addition, the pipes to be joined must be properly aligned prior to coupling to prevent leak-age through the band and these devices are of little assistance in obtaining the proper alignment. ~urthermore, because the bands must be of similar diam-eter and configuration to a pipe about which they must be placed, a different 2a size band must be manufactured for each diameter of pipe. If corrugated pipe is used, the band must have the corresponding corrugations. This need for such a variation in band size and configuration further increases the cost of production. In addition to the above shortcomings it is quite difficult to obtain a watertight seal using such a device. Because of the size of the band, quite often dirt or other objects become lodged between the band and the surface of the pipe to be covered, which prevents the obtaining of proper fitting and watertight seal.
V~3 It is therefore the principal object of this invention to provide an improved coupling device for joining lengths of pipe.
According to the invention there is provided a pipe coupling compris-ing flanged pipe sections~ said sections being in abutting relationship, an annular channeled coupling member having a bar and extended wall portions, said member being adapted to be positioned about said abutting flanges, said wall portions being integrally formed with said bar portion and extending perpendicularly from and inwardly of said bar portion along said flanges, the extended edges thereof abutting the adjacent pipe sections and said flanges extending into said annular channeled coupling member a distance greater than one-half the length of said wall portions to restrict lcngitudinal separation thereof, a pair of angle members, one of said anglemembers being secured to each end of said coupling member and each of said angle members having an aperture therein~ bolt means extending through said apertures and nut means adapted for threaded engagement with said bolt means whereby upon tightening said nut means about said bolt means, said angle members are drawn toward each other thereby tightening said coupler about said flanges.

Figure 6 is a plan view of the two-piece embodiment of the coupling ~126~3V8 member.
Referring now in detail to the drawings, the coupling device lO is comprised of a coupling member 12 and a gasket 14. In the preferred embodi-ment of the invention, as seen in Figure 2, the coupling member 12 is "U"
shaped, having a bar portion 16, way bore leg members 18 and defining a chan-nel 20. The ends of the pipe lengths 22, which are to be joined together, are flared, defining flange portions 24. In coupling, the pipe lengths 22 are positioned such that ~lange portions 24 abut each other. Coupling member 12 is rolled into a circular shape corresponding to the diameter of the pipe lengths to be joined. Gasket 14, which is constructed of neoprene of a suit-able rubber-like material, is positioned within channel 20 and the coupling member and gasket assembly is positioned over flange portions 24. The posi-tioning of the coupling member 22 over the flange portions dictates and in fact facilitates the proper alignment of the pipes prior to joining, which is necessary to obtain a proper seal. A tightening means 26 is secured to the open ends 28 of coupling member 12 and is operable to draw the ends 28 to-gether tightening the coupling member and gasket about the outer edges of flange portions 24 and securely coupling the pipe lengths 22. In the prefer-red embodiment, as shown in Figure 5, tightening means 26 consists of a pair of angles 30, each angle having an aperture 32 therein, bolt means 34 and nut 36, whereby upon tightening said nut and bolt means, the ends 28 of coupling member 12 are drawn together thereby forming the above described seal. To further improve and strengthen the seal, a second gasket 38 can be placed between the ends 28 of coupling member 12, as shown in Figure 5. Upon tight-ening, gasket 38 is compressed by said ends being forced together against said second gasket thereby preventing any leakage through the open ends of coupling member 12 and further strengthening the watertight seal of the coupling device ~1~6;3~
lO. The coupling device 10 thus provides an improved means for joining lengths of pipe which is stronger, both quicker and easier to install and provides a superior seal.
In a second embodiment of the invention, shown in Figure 3, a "V"
shaped coupling member 40 is used. The functioning of coupler member 40 is similar to that of coupling member 12 and upon tightening, forms a similar watertight seal. It should be further noted, that in conjunction with either coupling member 12 or coupling member 40 a sealant 42 can be positioned be-tween the open ends 44 of gasket 14 as shown in Figure 5 J thereby eliminating a possible weak point in the gasket and further increase the durability of the coupling device.
Another variation of the invention is shown in Figure 4. This em-bodiment differs from the preferred and second embodiment in that it replaces gasket 14 with gasket 46. Gasket 46, in addition to pressing against the outer surfaces of abutting flange portions 24 J extends between said flange portions and prevents any leakage therethrough. Gasket 46 can be used with either the "U" or "~" shaped channel members. It should be further noted, however, that in situations where watertight seals are not required, coupling member 12 can be positioned over flange portions 24 without any gasket. In 2Q such an embodiment, the coupling device provides a quick, strong and economical means for joining pipe lengths which utilizes the aligning features of the coupling member.
Figures 1, 2 and 3 show coupling device 10 joining corrugated pipe lengths 22. It should be noted that coupling device 10 is, of course, suited for joining all types of pipe lengths, it has an added benefit in joining corrugated pipe lengths in that it avoids the need for a sealing band with matching corrugations, which would increase the cost of production and general-11~63~8 ly provide an interior seal, due to the difficulty in obtaining the propermating surface between the outer corrugated surfaces of the pipc lengths and the inner surface of the band.
Finally, in yet another embodiment of the invention which is shown in Figure 6, the coupling member 12 is divided into two sections 48 and 50.
Each section is semi-circular in shape and has tightening means 26 secured to the open ends thereof. The sections are placed over the flange portions and the ends are drawn together in the same fashion as the open ends 28 in the previously discussed embodiments. A gasket 14 or 46 can be positioned within the channel of sections 48 and 50 to provide a watertight seal. This embodi-ment facilitates the joining of the pipe lengths by the increased case with which the coupling member can be positioned about the flange portions 24.
Various changes and modifications may be made in carrying out the present invention without departing from the scope and spirit thereof. Inso-far as these changes and modifications are within the purview of the appended claims they are to be considered as part of the invention.

Another variation of the invention is shown in Figure 4. This em-bodiment differs from the preferred and second embodiment in that it replaces gasket 14 with gasket 46.
