Abstract
Abstract A hose coupling through which extends a passage between two openings one of which is defined by a spigot and the other of which is defined by a sleeve, and wherein the spigot is of approximately the diameter of the spigot with the sleeve being adapted to receive a portion of hose to extend to the sleeve of an adjacent coupling so as to provide a sealing element joining two hose couplings which are attaching two hoses.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
228 words
A hose coupling fixed to the end of a first hose engaging a further coupling of the same configuration fixed to the end of another hose so that the two hoses are sealingly connected, said coupling comprising: a hollow body having a passage extending through it so as to terminate at one end in a first opening communicating with the hose and at the other end in a second opening facing the other coupling, said body having a spigot defining said first opening, said spigot having an outer diameter fitted within the end of the hose so as to to be retained therein, a sleeve defining said second opening, said sleeve having substantially the same outer diameter as said spigot and receiving a portion of hose extending to and over the sleeve of the other coupling so as to sealingly connect the two couplings, said body also having an annular flange co-axial and co-extensive with said sleeve and surrounding said sleeve so as to define an annular cavity between the sleeve and annular flange receiving the hose portion, cooperating locking means engaging the locking means of the other coupling preventing relative axial movement between the two couplings when in use, and wherein said flange projects longitudinally beyond said sleeve so as to support said hose portion between said couplings via cooperation of the flange of said other coupling.
Claim 2
Dependent Claim
228 words
A hose coupling fixed to the end of a first hose engaging a further coupling of the same configuration fixed to the end of another hose so that the two hoses are sealingly connected, said coupling comprising: a hollow body having a passage extending through it so as to terminate at one end in a first opening communicating with the hose and at the other end in a second opening facing the other coupling, said body having a spigot defining said first opening, said spigot having an outer diameter fitted within the end of the hose so as to to be retained therein, a sleeve defining said second opening, said sleeve having substantially the same outer diameter as said spigot and receiving a portion of hose extending to and over the sleeve of the other coupling so as to sealingly connect the two couplings, said body also having an annular flange co-axial and co-extensive with said sleeve and surrounding said sleeve so as to define an annular cavity between the sleeve and annular flange receiving the hose portion, cooperating locking means engaging the locking means of the other coupling preventing relative axial movement between the two couplings when in use, and wherein said flange projects longitudinally beyond said sleeve so as to support said hose portion between said couplings via cooperation of the flange of said other coupling.
Claim 3
Dependent Claim
29 words
The hose coupling of claim 1, wherein said flange projects beyond said sleeve a sufficient distance and abuts the sleeve of said other coupling when the couplings are engaged.
Claim 4
Dependent Claim
54 words
The hose coupling of claim 2 wherein said body has a plurality of angularly spaced abutments and a plurality of longitudinally extending arms with the arms being positioned relative to the abutments so that the arms engage the abutments of the other coupling so as to prevent axial movement between the two hose couplings.
