Abstract
Abstract A recovery buoy which is carried underwater by a diver and comprises an indented spool-like body of lightweight material around which is wrapped a cord. A weight is detachably mounted to the body and is attached to the cord so that the weight end of the cord can be attached to a structure to be recovered or marked, and when the body is released, its buoyancy causes it to rise, thereby unspooling the cord.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
266 words
A recovery and marker buoy, comprising: an enlongated body of buoyant material having axially opposite ends; a first flange member at one of said ends; a second flange member at the second one of said ends; a cylindrical central spindle intermediate said first and second flange members, said flange members including opposed frusto-conical surfaces interconnecting said flange members with said spindle; a location indicating head formed integrally with said first flange member on the axis of said body; a weight associated with said second flange member on the axis of said body; clamp means for detachably mounting said weight on said second flange member and being coupled to said weight; a line wound around said central spindle and having a first end, and a second end, said second end extending through said weight, in looped fashion, and being secured to said clamp means to securely retain said weight on the line second end upon detachment of said clamp means from said second flange member and dislodgement of said weight therefrom; and means for securing said first end of said line to said location indicating head and means for detachably mounting said weight to said second flange, whereby upon release of said weight from said second flange member and said body, anchoring of said weight at a selected location beneath water level may be effected and said line unreels from said central spindle under the buoyant force of said body, enabling the latter to freely float to the surface of the water, in which condition said location indicating head, upon surfacing, is operable to mark a location.
Claim 2
Dependent Claim
266 words
A recovery and marker buoy, comprising: an enlongated body of buoyant material having axially opposite ends; a first flange member at one of said ends; a second flange member at the second one of said ends; a cylindrical central spindle intermediate said first and second flange members, said flange members including opposed frusto-conical surfaces interconnecting said flange members with said spindle; a location indicating head formed integrally with said first flange member on the axis of said body; a weight associated with said second flange member on the axis of said body; clamp means for detachably mounting said weight on said second flange member and being coupled to said weight; a line wound around said central spindle and having a first end, and a second end, said second end extending through said weight, in looped fashion, and being secured to said clamp means to securely retain said weight on the line second end upon detachment of said clamp means from said second flange member and dislodgement of said weight therefrom; and means for securing said first end of said line to said location indicating head and means for detachably mounting said weight to said second flange, whereby upon release of said weight from said second flange member and said body, anchoring of said weight at a selected location beneath water level may be effected and said line unreels from said central spindle under the buoyant force of said body, enabling the latter to freely float to the surface of the water, in which condition said location indicating head, upon surfacing, is operable to mark a location.
Claim 3
Dependent Claim
57 words
The recovery and marker buoy of claim 1, further comprising means on said second flange member for tightly releasably retaining the wound line in position on said central spindle, the retaining member being embedded within the peripheral surface of said second flange member and preventing axial movement of said line second end relative to said central spindle.
Claim 4
Dependent Claim
55 words
The recovery and marker buoy of claim 2, wherein said retaining member on said second flange member is formed by a pair of ears defining a retaining notch therebetween, said notch clampingly engaging said line second end and operable to release said line second end upon disengagement of said weight from said second flange member.
Claim 5
Dependent Claim
28 words
The recovery and marker buoy of claim 1, further comprising marker strips disposed about said first and second flange members, in peripheral relation with the exterior surfaces thereof.
Claim 6
Dependent Claim
18 words
The recovery and marker buoy of claim 1, further comprising marker means on said first and second flange.
Claim 7
Dependent Claim
28 words
The recovery and marker buoy of claim 5, wherein said marker strips are disposed in recesses formed in the outer circumference of said first and second flange members.
Claim 8
Dependent Claim
47 words
The recovery and marker buoy of claim 1, wherein said means for securing said first end of said line to said location indicating head comprises a ring movably positioned in a passage formed in said head and being movably secured to said first end of said line.
Claim 9
Dependent Claim
21 words
The recovery and marker buoy of claim 7, wherein said first end terminates into a looped portion secured to said ring.
Claim 10
Dependent Claim
25 words
The recovery and marker buoy of claim 1, wherein said second end of said line terminates into a looped portion secured to said clamp means.
Claim 11
Dependent Claim
51 words
The recovery and marker buoy of claim 9 wherein said clamp means comprises a pair of unobstructed passages in said weight for the guidance of said second end therethrough, said passages having a diameter dimensioned such as to retain said looped portion in position on the outer face of said weight.
Claim 12
Dependent Claim
57 words
The recovery and marker buoy of claim 10, wherein said clamp means further comprises a stud member on the outer face of said second flange member, and comprising a clip member detachably secured on said stud member, said stud member extending through said weight, the latter being detachably retained on said stud member by said clip member.
Claim 13
Dependent Claim
25 words
The recovery and marker buoy of claim 11, wherein said stud member extends outwardly from said second flange, member on the axis of said body.
Claim 14
Dependent Claim
27 words
The recovery and marker buoy of claim 12, wherein said stud member comprises a cross hole and wherein said clip member is detachably positioned in said crosshole.
Claim 15
Dependent Claim
43 words
The recovery and marker buoy of claim 13, wherein said clip member is movably secured to said looped portion of said second line end, and wherein upon release of said clip member from said stud member, the former is retained on said weight.
Claim 16
Dependent Claim
24 words
The recovery and marker buoy of claim 14, wherein said weight has a circumference of a diameter approximating that of said second flange member.
Claim 17
Dependent Claim
26 words
The recovery and marker buoy of claim 1, wherein said buoyant material of said body is in the form of a foamed synthetic polymer composition material.
Claim 18
Dependent Claim
20 words
