Abstract
Abstract A high tension withstanding pull hose coupling including a first tubular water inlet pipe assembly mounted on a travelling support and including a rear inlet end opening outwardly in the direction opposite to the direction of movement of the support. The inlet end of the water inlet pipe assembly defines downstream tapering outer frusto-conical wedge surfaces and a wedge sleeve is loosely telescoped over the inlet end and includes downstream tapering inner frusto-conical wedge surfaces. An elongated tubular hose includes an outlet end telescoped over the outer wedge surfaces of the water inlet pipe assembly and the sleeve is telescoped over the hose outlet end with the wall portions of the hose outlet end clamped between the inner and outer conical surfaces of the sleeve and water inlet pipe assembly.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
186 words
In combination with an irrigation hose end portion, a tubular pipe section, one end of said section including tapering outer frusto-conical wedge surfaces over which said hose end portion is telescoped, a wedge sleeve including tapering inner frustoconical wedge surfaces tightly telescoped over said hose end portion, said wedge surfaces being in radial registry with each other, clampingly engaging said hose end portion therebetween and tapering away from said one end of said pipe section, a water inlet supply pipe supported from a traveling support and opening outwardly at its inlet end in a direction opposite to the direction of intended movement of said support, the other end of said tubular pipe section being loosely telescopingly engaged with said inlet end of said supply pipe, pressure responsive seal means disposed between the confronting telescoped inner and outer surfaces of said supply pipe and pipe section, said pipe and pipe section including pairs of axially spaced correspondingly relatively circumferentially displaced outwardly projecting anchor members, and a plurality of elongated tension members removably connected between each pair of corresponding anchor members outwardly of said pipe and pipe section.
Claim 2
Dependent Claim
186 words
In combination with an irrigation hose end portion, a tubular pipe section, one end of said section including tapering outer frusto-conical wedge surfaces over which said hose end portion is telescoped, a wedge sleeve including tapering inner frustoconical wedge surfaces tightly telescoped over said hose end portion, said wedge surfaces being in radial registry with each other, clampingly engaging said hose end portion therebetween and tapering away from said one end of said pipe section, a water inlet supply pipe supported from a traveling support and opening outwardly at its inlet end in a direction opposite to the direction of intended movement of said support, the other end of said tubular pipe section being loosely telescopingly engaged with said inlet end of said supply pipe, pressure responsive seal means disposed between the confronting telescoped inner and outer surfaces of said supply pipe and pipe section, said pipe and pipe section including pairs of axially spaced correspondingly relatively circumferentially displaced outwardly projecting anchor members, and a plurality of elongated tension members removably connected between each pair of corresponding anchor members outwardly of said pipe and pipe section.
Claim 3
Dependent Claim
49 words
The combination of claim 1 wherein the other end of said pipe section includes oppositely tapering outer frusto-conical surfaces, a second hose end portion telescoped over said oppositely tapering conical surfaces, and a second wedge sleeve including inner tapering conical surfaces tightly telescoped over said second hose end portion.
Claim 4
Dependent Claim
22 words
The combination of claim 1 wherein said tension members at at least slightly convergent toward the other end of said pipe section.
Claim 5
Dependent Claim
24 words
The combination of claim 1 wherein said one end of said pipe section is telescoped in the inlet end of said water supply pipe.
Claim 6
Dependent Claim
252 words
In combination with a hose end portion, a tubular pipe section, one end of said section including taperiNg outer frusto-conical wedge surfaces over which said hose end portion is telescoped, a wedge sleeve including tapering inner frusto-conical wedge surfaces tightly telescoped over said hose end portion said wedge surfaces being in radial registry with each other, clampingly engaging said hose end portion therebetween and tapering away from said one end of said pipe section, and anchor means carried by the other end of said tubular pipe section for applying an end-wise thrust thereto to advance said other end of said tubular pipe section in the direction in which it faces, said anchor means including an inlet supply pipe having opposite ends, the other end of said tubular pipe section being loosely telescopingly engaged with one end of said supply pipe, pressure responsive seal means disposed between the confronting telescoped inner and outersurfaces of said supply pipe and pipe section, said pipe and pipe section including pairs of axially spaced corresponding relatively circumferentially displaced outwardly projecting anchor members, a plurality of elongated tension members removably connected between each pair of corresponding anchor members outwardly of said pipe and pipe section, the other end of said inlet supply pipe being supported from a movable support adapted to be moved in the direction in which said other end of said supply pipe faces. is desired to disassemble the sleeve 70. Also, the inside assembly to prevent the sections 56 80 and 98 seizing the liners
