Abstract
Abstract A method and apparatus are disclosed for coupling a flexible hose to a metal tube. A metal reinforcing sleeve is placed over the outside of the tube, and a metal collar is placed over the outside of the reinforcing sleeve. The tube and reinforcing sleeve and collar are secured together by simultaneously bumping the tube and reinforcing sleeve to form, in a single operation, radially outwardly projecting beads on the tube and reinforcing sleeve on each side of the collar.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
236 words
A hose coupling comprising a metal tube having an interior and an exterior and a free end, a metal reinforcing sleeve having an interior and an exterior and a free end, a metal collar, and a flexible hose, the reinforcing sleeve being separate from the tube and being disposed on the exterior of the tube, the collar being disposed on the exterior of the reinforcing sleeve, the collar having a body portion closely adjacent the exterior of th reinforcing sleeve and spaced axially from the free Ends of the reinforcing sleeve and tube, the collar also having a skirt portion spaced radially outwardly of the exterior of the reinforcing sleeve and extending axially from the body portion toward the free ends of the tube and reinforcing sleeve, the hose being received within the skirt portion over the exterior of the reinforcing sleeve, the tube and reinforcing sleeve each being radially outwardly deflected and providing radially outwardly extending annular beads on at least the side of the collar body portion closest to the hose, and the bead of the tube extending into the bead of the reinforcing sleeve and being arranged such that the exterior of the tube sealingly engages the interior of the reinforcing sleeve at the location of the bead, whereby fluid leakage from the free end of the tube between the exterior of the tube and the interior of the reinforcing sleeve is prevented.
Claim 2
Dependent Claim
236 words
A hose coupling comprising a metal tube having an interior and an exterior and a free end, a metal reinforcing sleeve having an interior and an exterior and a free end, a metal collar, and a flexible hose, the reinforcing sleeve being separate from the tube and being disposed on the exterior of the tube, the collar being disposed on the exterior of the reinforcing sleeve, the collar having a body portion closely adjacent the exterior of th reinforcing sleeve and spaced axially from the free Ends of the reinforcing sleeve and tube, the collar also having a skirt portion spaced radially outwardly of the exterior of the reinforcing sleeve and extending axially from the body portion toward the free ends of the tube and reinforcing sleeve, the hose being received within the skirt portion over the exterior of the reinforcing sleeve, the tube and reinforcing sleeve each being radially outwardly deflected and providing radially outwardly extending annular beads on at least the side of the collar body portion closest to the hose, and the bead of the tube extending into the bead of the reinforcing sleeve and being arranged such that the exterior of the tube sealingly engages the interior of the reinforcing sleeve at the location of the bead, whereby fluid leakage from the free end of the tube between the exterior of the tube and the interior of the reinforcing sleeve is prevented.
Claim 3
Dependent Claim
35 words
A hose coupling as set forth in claim 1 wherein the exterior of the bead of the tube and the interior of the bead of the reinforcing sleeve are squeezed together both axially and radially.
Claim 4
Dependent Claim
84 words
A hose coupling as set forth in claim 1 wherein the tube and reinforcing sleeve are each radially outwardly deflected at axially spaced locations on each side of the collar body portion, thereby providing radially outwardly extending annular beads on both sides of the collar body portion, and the beads of the tube extend into the beads of the reinforcing sleeve and are arranged such that the exterior of thetube sealingly engages the interior of the reinforcing sleeve at the location of the beads.
Claim 5
Dependent Claim
43 words
A hose coupling as set forth in claim 3 wherein the exterior of at least one of the beads of the tube and the interior of at least one of the beads of the reinforcing sleeve are squeezed together both axially and radially.
Claim 6
Dependent Claim
40 words
A hose coupling as set forth in claim 1 wherein the reinforcing sleeve extends axially rearwardly away from the collar body portion in a direction away from the free ends, thereby providing added strength to the tube adjacent the collar.
Claim 7
Dependent Claim
24 words
A hose coupling as set forth in claim 1 wherein the collar skirt portion is deflected radially inwardly to secure the hose in place.
Claim 8
Dependent Claim
290 words
A hhose coupling comprising a metal tube having an interior and an exterior and a free end, a metal reinforcing sleeve having an interior and an exterior and a free end, a metal collar, and a flexible hose, the reinforcing sleeve being separate from the tube and being disposed on the exterior of the tube, the collar being disposed on the exterior of the reinforcing sleeve, the free end of the reinforcing sleeve being adjacent the free end of the tube, the collar having a body portion closely adjacent the exterior of the reinforcing sleeve and spaced axially from the free ends of the reinforcing sleeve and tube, the collar also having a skirt portion spaced radially outwardly of the exterior of the reinforcing sleeve and extending axially from the body portion toward the free ends of the tube and reinforcing sleeve, the hose being received within the skirt portion over the exterior of the reinforcing sleeve, the reinforcing sleeve being of substantially greater axial extent than the collar, the reinforcing sleeve extending axially coextensively with the skirt portion and body portion of the sleeve and extending axially rearwardly beyond the body portion in a direction away from the free ends, the tube and reinforcing sleeve each being radially outwardly deflected and thereby providing radially outwardly extending annular beads on each side of the collar body portion, and the beads of the tube extending into the beads of the reinforcing sleeve and being arranged such that the exterior of the tube sealingly engages the interior of the reinforcing sleeve at the location of the beads, whereby fluid leakage from the free end of the tube between the exterior of the tube and the interior of the reinforcing sleeve is prevented.
Claim 9
Dependent Claim
290 words
A hhose coupling comprising a metal tube having an interior and an exterior and a free end, a metal reinforcing sleeve having an interior and an exterior and a free end, a metal collar, and a flexible hose, the reinforcing sleeve being separate from the tube and being disposed on the exterior of the tube, the collar being disposed on the exterior of the reinforcing sleeve, the free end of the reinforcing sleeve being adjacent the free end of the tube, the collar having a body portion closely adjacent the exterior of the reinforcing sleeve and spaced axially from the free ends of the reinforcing sleeve and tube, the collar also having a skirt portion spaced radially outwardly of the exterior of the reinforcing sleeve and extending axially from the body portion toward the free ends of the tube and reinforcing sleeve, the hose being received within the skirt portion over the exterior of the reinforcing sleeve, the reinforcing sleeve being of substantially greater axial extent than the collar, the reinforcing sleeve extending axially coextensively with the skirt portion and body portion of the sleeve and extending axially rearwardly beyond the body portion in a direction away from the free ends, the tube and reinforcing sleeve each being radially outwardly deflected and thereby providing radially outwardly extending annular beads on each side of the collar body portion, and the beads of the tube extending into the beads of the reinforcing sleeve and being arranged such that the exterior of the tube sealingly engages the interior of the reinforcing sleeve at the location of the beads, whereby fluid leakage from the free end of the tube between the exterior of the tube and the interior of the reinforcing sleeve is prevented.
