Abstract
Abstract This Patent discloses a hose coupling including a nipple for insertion into a hose, the nipple having circumferentially extending recesses including leading and trailing ramp portions having roughened or serrated surfaces thereon. After insertion of the nipple into the hose, a segmented collar having circumferentially extending projections on the interior thereof, including leading and trailing ramp portions having roughened or serrated surfaces thereon, is positioned to circumscribe the nipple and overlie and press the hose into the recesses. In order to retain or prevent radial disengagement of the collar from the hose, a retaining ferrule is positioned circumferentially of the collar.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
117 words
A hose coupling comprising a nipple for insertion into a hose, said nipple having circumferentially extending recesses, and projections; a segmented, axially floating collar having circumferentially extending corresponding projections and recesses on the interior thereof adapted to circumscribe the nipple, the projections on said nipple and said collar, when operatively assembled overlying, engaging and pressing the hose into said recesses; and a retaining ferrule adapted to circumferentially engage said floating collar to prevent radial disengagement of said collar from said hose, said projections of said nipple interfering in axially spaced relation with the projections on said collar while permitting relative axial movement between said collar and said nipple upon the application of hydraulic pressure in said coupling.
Claim 2
Dependent Claim
117 words
A hose coupling comprising a nipple for insertion into a hose, said nipple having circumferentially extending recesses, and projections; a segmented, axially floating collar having circumferentially extending corresponding projections and recesses on the interior thereof adapted to circumscribe the nipple, the projections on said nipple and said collar, when operatively assembled overlying, engaging and pressing the hose into said recesses; and a retaining ferrule adapted to circumferentially engage said floating collar to prevent radial disengagement of said collar from said hose, said projections of said nipple interfering in axially spaced relation with the projections on said collar while permitting relative axial movement between said collar and said nipple upon the application of hydraulic pressure in said coupling.
Claim 3
Dependent Claim
19 words
A hose coupling in accordance with claim 1 said nipple including leading and trailing ramp portions in said recesses.
Claim 4
Dependent Claim
17 words
A hose coupling in accordance with claim 2 wherein said ramp portions include serrated surface portions thereon.
Claim 5
Dependent Claim
31 words
A hose coupling in accordance with claim 2 wherein said segmented collar includes leading and trailing ramp portions adapted for cooperation in superimposed overlying relation with respective ramps of said nipple.
Claim 6
Dependent Claim
22 words
A hose coupling in accordance with claim 4 wherein said leading and trailing ramp portions of said collar include a roughened surface.
Claim 7
Dependent Claim
30 words
A hose coupling in accordance with claim 4 wherein the slope of the ramps associated with said collar are greater than the slope of the ramps associated with said nipple.
Claim 8
Dependent Claim
19 words
A hose coupling in accordance with claim 4 wherein said ramps of said collar and said nipple are serrated.
Claim 9
Dependent Claim
84 words
A hose coupling in accordance with claim 1 wherein said nipple includes leading and trailing ramp portions defining said recesses; said segmented collar including leading and trailing ramp portions adapted for cooperation in superimposed overlying relation with respective ramps of said nipple, the slope of said ramps of said collar being greater than the slope of the ramps associated with said nipple, the diameter of said collar at its innermost projection being less than the diameter of hose engageable by said nipple and collar.
Claim 10
Dependent Claim
33 words
A hose coupling in accordance with claim 1 wherein said retaining ferrule includes an in-turned shoulder at the leading edge thereof adapted to be axially spaced from the terminal end of said hose.
Claim 11
Dependent Claim
33 words
A hose coupling in accordance with claim 9 wherein said ferrule includes a tapered trailing portion to effect a wedging action against said collar when said ferrule is positioned to circumscribe said collar.
Claim 12
Dependent Claim
99 words
A hose coupling comprising a nipple for insertion into a hose, said nipple having circumferentially extending recesses and projections; a segmented, axially floating collar having circumferentially extending corresponding projections and recesses on the interior thereof to circumscribe the nipple, the projections on said nipple and said collar, when operatively assembled, overlying, engaging and pressing the hose into said recesses; and means to prevent radial disengagement of said floating collar from said hose said projections of said nipple interfering in axially spaced relation with the projections of said collar while permitting axial movement of said collar relative to said nipple.
Claim 13
Dependent Claim
99 words
A hose coupling comprising a nipple for insertion into a hose, said nipple having circumferentially extending recesses and projections; a segmented, axially floating collar having circumferentially extending corresponding projections and recesses on the interior thereof to circumscribe the nipple, the projections on said nipple and said collar, when operatively assembled, overlying, engaging and pressing the hose into said recesses; and means to prevent radial disengagement of said floating collar from said hose said projections of said nipple interfering in axially spaced relation with the projections of said collar while permitting axial movement of said collar relative to said nipple.
Claim 14
Dependent Claim
45 words
A hose coupling in accordance with claim 11 including leading and trailing ramp portions in said recesses, and leading and trailing ramp portions in said collar, said ramp portions of said collar adapted for cooperation in superimposed overlying relation with respective ramps of said nipple.
Claim 15
Dependent Claim
34 words
A hose coupling in accordance with claim 12 wherein the slope of at least some of the ramps associated with said collar are greater than the slope of corresponding ramps associated with said nipple.
