Abstract A diving helmet includes a cylindrical portion with a dome shaped top for the head and neck of a user. An air line is attached to a fitting adjacent the dome shaped top and to one side and rear thereof while a slight glass is held in a protrusion extending forwardly from the cylindrical portion. The cylindrical portion terminates in a rim designed to fit over the shoulders, front chest and rear torso of the user, and the rim is weighted with lead weights. The cylindrical portion dome and rim are preferably formed of fiberglass and in the rim the fiberglass completely surrounds the lead. On the under side of the rim on each side thereof there is attached as by gluing flexible pockets consisting of water inpenetrateable leaves stitched together so that one leaf will remain glued to the bottom of the rim while the other leaf is free to open under the pressure of air within the helmet when it is not in use but to close against the other leaf when contacted by the shoulders of a user. The leaves increase the volume of air within the helmet when not in use to provide floatation, but the volume is decreased when in use so that the helmet will remain in place without the necessity of straps.

66 words
A diving helmet comprising a substantially cylindrical member having a domed top; a forwardly protruding member on said cylindrical member and containing a sight glass; a rim connected to said cylindrical portion and contoured to fit the chest, shoulders and rear torso of a diver, said cylindrical member, domed top and rim being formed of fiberglass, and lead weight carried in and surrounded by said rim.
Claim 2
Dependent Claim
66 words
A diving helmet comprising a substantially cylindrical member having a domed top; a forwardly protruding member on said cylindrical member and containing a sight glass; a rim connected to said cylindrical portion and contoured to fit the chest, shoulders and rear torso of a diver, said cylindrical member, domed top and rim being formed of fiberglass, and lead weight carried in and surrounded by said rim.
Claim 3
Dependent Claim
58 words
A diving helmet as set forth in claim 1 in which said rim has a bottom, a pair of leaves stitched together with one of said leaves cemented to said bottom and the other leaf free to open downwardly when no diver is in the helmet to increase the effective volume of the helmet and render it floatable.
Claim 4
Dependent Claim
47 words
A diving helmet as set forth in claim 2 in which said other leaf is arranged to collapse against said cemented leaf when engaged by the shoulders of a diver to render the helmet non-floatable and securely affixed to the diver in the absence of securing straps.
Claim 5
Dependent Claim
41 words
A diving helmet as set forth in claim 1 in which an air fitting is attached to said helmet to one side and to the rear thereof to provide for supplying air so as to clear moisture from said sight glass.
Claim 6
Dependent Claim
41 words
A diving helmet as set forth in claim 3 in which an air fitting is attached to said helmet to one side and to the rear thereof to provide for supplying air so as to clear moisture from said sight glass.
Claim 7
Dependent Claim
19 words
A diving helmet as set forth in claim 3 which is of a bright yellow color for easy recognition.
Claim 8
Dependent Claim
