Abstract
IMPROVED IRRIGATION PIPE COUPLER
Abstract The specification discloses a torque coupling having two tubular coupling member having flanges with interlocking teeth wedged together by a clamping ring. The flanges have opposed grooves in which are positioned elastomer sealing rings having shallow grooves with sharp edges forming vacuum seals with the bottoms of the grooves in the flanges, the rings being pressed together.

Description
10977~6 This invention relates to an improved irrigation pipe coupler, and has for an object thereof the provision of a new and improved irrigation pipe couplerO
According to the present invention there is provided in an improved irrigation pipe coupler, a pair of pipe coupler members having opposing flanges with annular grooves having substantially planar bottoms, a pair of sealing rings each having in a first side thereof an annular shallow groove therein V-shaped in transverse cross-section and bordered by a single pair of sharp sealing edges, each groove extending entirely around the sealing ring, the side of each ring opposite to the first side being substantially semi-circular in transverse cross-section, and means for pressing the flanges together to press the sealing edges against the planar bottoms of the grooves in the flanges to form vacuums in the grooves in the rings, the rings normally fitting closely in and projecting beyond the grooves in the flanges and being compressed tightly in the grooves in the flanges by the pressing meansO
In the accompanying drawings which illustrate an exemplary embodiment of the present invention:
Figure 1 is a partially sectional view of an improved irrigation pipe coupler forming one embodiment of the invention;
Figure 2 is an enlarged, fragmentary, vertical section of the coupler of Figure l;
Figure 3 is an enlarged, perspective view of a sealing ring of the coupler of Figure l; and Figure 4 is an enlarged, section taken along line 4-4 of Figure 3O
An improved irrigation pipe coupler 10 forming a specific embodimen~ of the invention includes a pair of short, ~,,3 ~
109~
identical coupler members 12 releasably clamped together with a wedging action by a split ring 14 and in sealing and torquing engagement with two irrigation pipes (not shown)O The members 12 include interlocking teeth 16 on flanges 18~ and have annu-lar grooves 20 facing each otherO All the above structure is old and known prior to my inventionO
Two vacuum sealing rings 22 form vacuum seals with bottoms 24 of the grooves 20~ and are compressed against each other to form seals around the entire coupling membersO The sealing rings are composed of a tough, resilient elastomer com- !
poundO One compound well suited for this is a EPDM having a durometer of sixty (60)o As best shown in Figures 2 and 4~ one entire side 26 of each ring is convex or semi-circular in trans-verse cross-sectionO The other side has a continuous shallow groove 28~ In the example shown, the groove is V-shaped in transverse cross-section and subtends an angle of 96 to form sharp edges 30 (90) with bevelled outer surfaces 32 extending from tapered inner and outer surfaces 34 and 36 forming angles of 6 with tangents to the inner and outer circumferences of 20 the ring to enable the rings to be easily inserted into the annular grooves 200 When the split clamping ring 14 is closed, it presses the sealing rings 22 tightly together and against the bottoms 24 of the grooves 20~ thereby forcing air out of the spaces defined by the V-shaped grooves 28 and the bottoms 24 of the annular grooves 200 Thus, any force tending to pull the rings 22 away from the bottoms 24 of the grooves 20 will be opposed by a partial vacuum induced by the tendency of the air spaces defined by the V-shaped grooves to expand with the resilient expansion of the rings 220 The function is somewhat analogous ~;
~ 7~
109~6 to that of the conventional rubber suction cup. The engaging sides of the sealing rings are sealed tightly Logether and the V-vacuum seals are formed with the smooth planar bottoms 24 of the grooves 20~ These seals are so good that adhesive sealing compounds are not necessary to make the joints completely water'ight at high pressures, eOgO 150 poSoio However, the rings 22 easily separate from each other as the coupling members 12 are taken apartO
