Abstract
Abstract A messenger buoy recovery device which can be attached by a diver to a submerged object including a spool for exteriorly winding recovery cable, the spool having an interior receptacle; an inflatable float which is adapted to be received within said receptacle; means for retaining the float in the receptacle in a deflated condition; and the flat having means for manually pulling the float from the receptacle. The float may be retained within the receptacle by friction between the float and the wall of the receptacle, and means may be provided for automatically inflating the buoy when the buoy is pulled from the receptacle. The recovery device may further include a winding assembly which has a winding spindle which is adapted to be received by the spool receptacle, and means may be provided for retaining the spool to the winding spindle.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
123 words
A messenger buoy recovery device comprising: a spool for exteriorly winding a lifting cable; said spool having an interior receptacle; an inflatable float which is adapted to be received within said receptacle; means for retaining the float in the receptacle in a deflated condition; the float having means for manually pulling the float from the receptacle, and being capable upon inflation, of floating the spool with said lifting cable toward the surface of the water; and means connecting the float to the spool for pulling the spool upwardly in the water with the longitudinal axis of the spool substantially vertical, whereby the lifting cable unwinds from the spool which is in a nonrotative state as the spool and float ascend in the water.
Claim 2
Dependent Claim
123 words
A messenger buoy recovery device comprising: a spool for exteriorly winding a lifting cable; said spool having an interior receptacle; an inflatable float which is adapted to be received within said receptacle; means for retaining the float in the receptacle in a deflated condition; the float having means for manually pulling the float from the receptacle, and being capable upon inflation, of floating the spool with said lifting cable toward the surface of the water; and means connecting the float to the spool for pulling the spool upwardly in the water with the longitudinal axis of the spool substantially vertical, whereby the lifting cable unwinds from the spool which is in a nonrotative state as the spool and float ascend in the water.
Claim 3
Dependent Claim
31 words
A combination as claimed in claim 1 comprising: said means for retaining the float in the receptacle including the float in the deflated condition frictionally engaging the wall of the receptacle.
Claim 4
Dependent Claim
38 words
A combination as claimed in claim 1 comprising: a winding assembly which includes a winding spindle means; said receptacle being adapted to receive the winding spindle means; and means for retaining the spool to the winding spindle means.
Claim 5
Dependent Claim
22 words
A combination as claimed in claim 1 comprising: means for automatically inflating the float when the float is pulled from the receptacle.
Claim 6
Dependent Claim
31 words
A combination as claimed in claim 4 comprising: the automatic inflating means including; said float having a lever actuable CO2 firing mechanism means; and said lever being connected to the spool.
Claim 7
Dependent Claim
46 words
A comBination as claimed in claim 5 comprising: said lever being connected to the spool by a flexible line which is of such a length to restrain the lever for actuation of the firing mechanism after the float has been pulled substantially clear of the receptacle.
Claim 8
Dependent Claim
49 words
A combination as claimed in claim 6 comprising: said spool having a substantially closed end which forms the bottom of the receptacle; and one end of the flexible line being connected to the bottom of the receptacle and the other end of the line being connected to said lever.
Claim 9
Dependent Claim
45 words
A combination as claimed in claim 7 comprising: the float being elongated in a deflated condition; said firing mechanism being connected to one end of the float; and the manual pulling means including a handle which is connected to the other end of the float.
Claim 10
Dependent Claim
31 words
A combination as claimed in claim 8 comprising: said means for retaining the float in the receptacle including the float in the deflated condition frictionally engaging the wall of the receptacle.
Claim 11
Dependent Claim
47 words
A combination as claimed in claim 9 comprising: a winding assembly including: a stand; and a crank and winding spindle means rotatably mounted to the stand; said receptacle being adapted to receive the winding spindle means; and means for retaining the spool to the winding spindle means.
