Abstract
Abstract A rigid foamed synthetic plastic in a generally spherical shape is provided with a groove around its entire periphery fixedly receiving one end of a line having its intermediate portion generally uniformly wound within the groove. The wound line is covered and securely held within the groove by means of one or more encircling resilient bands, with the opposite end of the line extending between the bands or from underneath one band to its connection with a weight. When marking a spot in the water, the weight will pull the line from beneath the rubber band or bands, which act as an unwinding brake, until the weight strikes the bottom of the body of water with the foamed plastic sphere floating on top of the water; thereafter, the band will resist or prevent further unwinding of the line. To prevent unwinding of the line, a second resilient band may be provided in a plane perpendicular to and encircling the first band. Tabs on the bands will facilitate their removal, when desired.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
125 words
A marking float, comprising: a float body having an average specific gravity substantially less than that of water; a peripheral groove about the exterior of said float body; means for attaching a weight having an average specific gravity substantially greater than that of water; a line having said means for attaching a weight at one end and being wound within said groove about the periphery of said float body; and line unwinding braking means comprising an annular substantially flat resilient band having a width substantially equal to that of said groove, said band overlying said groove and generally covering the wound line for braking and controlling unwinding of the line as the body rotatably floats on water and an attached weight sinks within the water.
Claim 2
Dependent Claim
125 words
A marking float, comprising: a float body having an average specific gravity substantially less than that of water; a peripheral groove about the exterior of said float body; means for attaching a weight having an average specific gravity substantially greater than that of water; a line having said means for attaching a weight at one end and being wound within said groove about the periphery of said float body; and line unwinding braking means comprising an annular substantially flat resilient band having a width substantially equal to that of said groove, said band overlying said groove and generally covering the wound line for braking and controlling unwinding of the line as the body rotatably floats on water and an attached weight sinks within the water.
Claim 3
Dependent Claim
41 words
The marking float of claim 1 wherein said annular resilient band comprises two annular resilient bands extending generally side by side within said groove, and together completely overlying the wound line, with said line extending between said bands to a weight.
Claim 4
Dependent Claim
35 words
The marking float of claim 1, including at least one homogeneously integral outwardly projecting tab on said resilient band to constitute gripping means for assisting in the removal of the band from the float body.
Claim 5
Dependent Claim
43 words
The marking float of claim 1, including a resilient locking band extending around the periphery of said float body generally perpendicular to said first-mentioned band, and overlying said first-mentioned band and wound line to constitute means for preventing the unwinding of the line.
Claim 6
Dependent Claim
40 words
The marking float of claim 4, wherein said locking band includes at least one outwardly projecting homogeneously integral tab means for grasping between fingers to assist in the removal of the locking band immediately prior to using the marking float.
Claim 7
Dependent Claim
29 words
The marking float of claim 4, wherein said body includes two diametrically opposed separate notches separate from said groove, each receiving therein diametrically opposed portions of said locking band.
Claim 8
Dependent Claim
13 words
The marking device of claim 1, wherein said float body is generally spherical.
Claim 9
Dependent Claim
33 words
The marking float of claim 7, wherein said groove is defined by a bottom surface and connecting side surfaces leading outwardly from the bottom surface to the outer surface of the float body.
Claim 10
Dependent Claim
21 words
The marking float of claim 7, wherein said body includes two generally parallel annular outwardly formed ribs defining therebetween said groove.
Claim 11
Dependent Claim
18 words
The marking device of claim 1, wherein said float body is constructed entirely of rigid foamed synthetic plastic.
