Abstract
Abstract There is disclosed a self-contained underwater breathing arrangement including a cap or helmet for a skin diver having a hollow walled arrangement wherein air may be stored for rebreathing as needed. Additionally, there is disclosed, with and without such a combination a snorkel attachment for breathing purposes secured to such a cap having an elongated tube adapted and constructed to extend to the surface of a body of water. The tube terminating on a reel mounted on a floating structure whereby the tube may be wound thereon and unwound as desired.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
182 words
Breathing apparatus comprising a float, a reel mounted on said float, said reel having a tubular axle, a hose wound on said reel, one end of said hose connected to means whereby said hose is in internal communication with said tubular axle, a fixed tubular fitting means communicating with one end of said tubular axle, said hose affixed at one end to said fixed tubular fitting, the other end of said hose terminating with one end of a coupling, said other end of said coupling affixed to a first conduit, a flexible cap having an inner lining and an outer cover of relatively elastomeric material hermetically bound together at their peripheral edges thereby defining a space therebetween, said cap having secured thereto a second conduit means having means for unobstructed communication with said defined space, said second conduit terminating in a mouthpiece, said cap further comprising a depending skirt portion adapted and constructed to cover the nape of a diver, said skirt portion having retaining means for said conduit, said first conduit extending forwardly of said cap and terminating in a mouthpiece
Claim 2
Dependent Claim
182 words
Breathing apparatus comprising a float, a reel mounted on said float, said reel having a tubular axle, a hose wound on said reel, one end of said hose connected to means whereby said hose is in internal communication with said tubular axle, a fixed tubular fitting means communicating with one end of said tubular axle, said hose affixed at one end to said fixed tubular fitting, the other end of said hose terminating with one end of a coupling, said other end of said coupling affixed to a first conduit, a flexible cap having an inner lining and an outer cover of relatively elastomeric material hermetically bound together at their peripheral edges thereby defining a space therebetween, said cap having secured thereto a second conduit means having means for unobstructed communication with said defined space, said second conduit terminating in a mouthpiece, said cap further comprising a depending skirt portion adapted and constructed to cover the nape of a diver, said skirt portion having retaining means for said conduit, said first conduit extending forwardly of said cap and terminating in a mouthpiece
Claim 3
Dependent Claim
72 words
The apparatus of claim 1 wherein the coupling means includes an open ended housing attached to said hose and an open ended housing attached to one end of said first conduit, said housings having normally closed valve means with outwardly urged projecting means whereby said valves are opened when said housing are axially brought together in a manner so that said relative projections are in abutment, said housings having means to couple.
Claim 4
Dependent Claim
19 words
The apparatus of claim 1 wherein the other end of said fixed tubular fitting terminates in a check valve.
Claim 5
Dependent Claim
76 words
A diver's cap having an inner lining and an outer cover of highly elastomeric material hermetically bound together at their peripheral edges thereby defining an expansible space therebetween, rebreathing means for said diver including a conduit secured to said cap, means for unobstructed communication between said defined space and said conduit, and a mouthpiece terminating said conduit, whereby air exhaled by said diver may be temporarily stored in said spaced and thereafter inhaled by said diver.
Claim 6
Dependent Claim
76 words
A diver's cap having an inner lining and an outer cover of highly elastomeric material hermetically bound together at their peripheral edges thereby defining an expansible space therebetween, rebreathing means for said diver including a conduit secured to said cap, means for unobstructed communication between said defined space and said conduit, and a mouthpiece terminating said conduit, whereby air exhaled by said diver may be temporarily stored in said spaced and thereafter inhaled by said diver.
