Abstract
Abstract A yoke for attaching a tank valve to an inlet fitting of the regulator has a threaded base ring telescoped over the inlet fitting, the base ring engaging a lead screw journalled on the base of the fitting. Rotation of the lead screw moves the yoke to clamp or release the tank valve. A ball is clamped by the yoke against the inlet fitting to exclude moisture when the regulator is not in use.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
196 words
In breathing apparatus of the class described cooperable with a valve projection of an air bottle: a. a regulator body having an inlet fitting, there being an inlet opening at the end of the fitting for admission of breathable gases into the regulator body, said regulator body having means forming an outlet; b. a lead screw journalled on the inlet fitting and confined against axial movement; and c. a yoke, said yoke having i. a threaded base ring telescoped over said inlet fitting and engaging said lead screw; and ii. a bridge attached to said base ring, and projecting across said inlet opening at the end of said fitting, and forming a space for the reception of said valve projection; d. angular movement of said lead screw causing said bridge to move toward or away from said inlet opening to clamp or release said tank valve projection; e. said lead screw having a handle part located between the end of said base ring and said regulator body to be removed from a place of possible entanglement with kelp, lines or the like while being of a size adequate to permit easy rotation of said lead screw.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
46 words
The combination as set forth in claim 1 in which said inlet fitting is formed as a part separate from said regulator body, and having a flange at its outer end to confine said lead screw on said fitting, said base ring fitting over said flange.
Claim 4
Dependent Claim
23 words
The combination as set forth in claim 2 in which said base ring is internally threaded and said lead screw is externally threaded.
Claim 5
Dependent Claim
27 words
The combination as set forth in claim 1 in which said handle part is a knurled generally circular flange located at the base of the lead screw.
Claim 6
Dependent Claim
58 words
The combination as set forth in claim 1 together with a ball closure and apertured tether formed as a unitary molded article of neoprene or rubber-like material, said regulator including a hose threaded through said apertured tether, said ball closure being cooperable With said inlet opening and said bridge to seal said inlet opening from entry of moisture.
