Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 144 words
A fluid-coupling assembly, comprising: a. a pair of rigid housings having faces which confront and engage each other, each having at least one cylindrical rigid bore extending therethrough aligned with the bore of the other housing; b. at least one of said housings being adapted to snugly receive a flexible hose in at least said one of its cylindrical bores; c. a rigid barbed ferrule for being disposed in the end of the hose with its barbs disposed within said one bore for urging said hose against said one housing, said ferrule having a cylindrical portion directly received in and directly engaging a cylindrical portion of said one bore and projecting from said one bore through said faces and directly received in and directly engaging a cylindrical portion of said bore of said other housing; and d. means for detachably holding said housings together.
Claim 2
Dependent Claim 144 words
A fluid-coupling assembly, comprising: a. a pair of rigid housings having faces which confront and engage each other, each having at least one cylindrical rigid bore extending therethrough aligned with the bore of the other housing; b. at least one of said housings being adapted to snugly receive a flexible hose in at least said one of its cylindrical bores; c. a rigid barbed ferrule for being disposed in the end of the hose with its barbs disposed within said one bore for urging said hose against said one housing, said ferrule having a cylindrical portion directly received in and directly engaging a cylindrical portion of said one bore and projecting from said one bore through said faces and directly received in and directly engaging a cylindrical portion of said bore of said other housing; and d. means for detachably holding said housings together.
Claim 3
Dependent Claim 30 words
A fluid-coupling assembly according to claim 1 which includes a plurality of said ferrules respectively disposed in said one housing and for being disposed into a plurality of flexible hoses.
Claim 4
Dependent Claim 30 words
A fluid-coupling according to claim 2, each of said ferrules having a fluid seal on said cylindrical portion engaging the cylindrical portion of the aligned bore in said other housing.
Claim 5
Dependent Claim 56 words
A fluid-coupling according to claim 1 in which each of the aligned bores has a cylindrical counterbore opening into the faces of said housings and with an annular shoulder disposed in each of said counterbores, said ferrule having an enlarged cylindrical portion disposed in both of said counterbores and trapped by and between said annular shoulders.
Claim 6
Dependent Claim 38 words
A fluid-coupling according to claim 4 in which said enlarged cylindrical portion is engaged by both of said annular shoulders, said holding means being adjustable whereby said housings are clamped against said enlarged portion by said holding means.
Claim 7
Dependent Claim 164 words
A fluid-coupling assembly, comprising: a. a pair of rigid housings having faces which confront each other, each having at least one bore aligned with the bore of the other housing, each of said bores of both of said housings having a counterbore terminating at said faces and defining an internal annular shoulder, said housings being adapted to receive a flexible hose in said bores; b. a plurality of flexible hoses having ends respectively disposed substantially at said annular shoulders; c. a plurality of rigid barbed ferrules identical to each other disposed in the ends of the hoses within said bores and also respectively disposed in said counterbores and having enlarged portions engaging said annular shoulders, said ferrules in one of said housings projecting from its said bore through said faces into the aligned counterbore in the other housing; d. a fluid seal between the ferrules of both housings and the counterbores in said other housing; and e. means for detachably holding said housings together.
Claim 8
Dependent Claim 164 words
A fluid-coupling assembly, comprising: a. a pair of rigid housings having faces which confront each other, each having at least one bore aligned with the bore of the other housing, each of said bores of both of said housings having a counterbore terminating at said faces and defining an internal annular shoulder, said housings being adapted to receive a flexible hose in said bores; b. a plurality of flexible hoses having ends respectively disposed substantially at said annular shoulders; c. a plurality of rigid barbed ferrules identical to each other disposed in the ends of the hoses within said bores and also respectively disposed in said counterbores and having enlarged portions engaging said annular shoulders, said ferrules in one of said housings projecting from its said bore through said faces into the aligned counterbore in the other housing; d. a fluid seal between the ferrules of both housings and the counterbores in said other housing; and e. means for detachably holding said housings together.
