Abstract
Abstract A proximity comparing device for golfers for determining relative distances of golf balls from a flagstick which includes a clamping ring to releasably engage the flagstick while permitting sliding movement of the clamping ring about the periphery of the flagstick in combination with a string which has one end anchored to the clamping ring and another end received in a reel. The reel is preferably formed with an inner opening which is just slightly larger than the diameter of a ball so that adjustable amounts of string are played out or received in the reel making it a relatively simple matter to determine promptly which of two golf balls is farthest from the flagstick.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
121 words
A proximity comparing device for golfers to determine relative distance of golf balls from a flagstick comprising: a clamping ring releasably engageable with said flagstick and having a sufficiently low coefficient of friction to be slidable about the periphery thereof while engaging said flagstick, a string having one end anchored to said clamping ring, and a reel securing the opposite end of said string and providing a variable amount of string for measuring distances from said flagstick, said reel including a pair of concentric inner and outer rings rotatable relative to each other, the other end of said string being wound about said inner ring and said outer ring permitting entry and withdrawal of said string from about said inner ring.
Claim 2
Dependent Claim
121 words
A proximity comparing device for golfers to determine relative distance of golf balls from a flagstick comprising: a clamping ring releasably engageable with said flagstick and having a sufficiently low coefficient of friction to be slidable about the periphery thereof while engaging said flagstick, a string having one end anchored to said clamping ring, and a reel securing the opposite end of said string and providing a variable amount of string for measuring distances from said flagstick, said reel including a pair of concentric inner and outer rings rotatable relative to each other, the other end of said string being wound about said inner ring and said outer ring permitting entry and withdrawal of said string from about said inner ring.
Claim 3
Dependent Claim
24 words
A device according to claim 1 in which: said inner ring has an internal diameter slightly larger than the diameter of a golf ball.
Claim 4
Dependent Claim
23 words
A device according to claim 1 which includes: a pin on said inner ring for rotating said inner ring within said outer ring.
Claim 5
Dependent Claim
53 words
A device according to claim 1 in which: said outer ring has an aperture through which said string extends, and said inner ring has an arcuate groove extending radially inwardly from its outer periphery receiving the string passing through said aperture and functioning to permit level winding of said string within said groove.
Claim 6
Dependent Claim
32 words
A device according to claim 4 in which: said arcuate groove has an aperture therethrough at the inner extremity of said groove, said string passing through said aperture and being secured thereagainst.
Claim 7
Dependent Claim
21 words
A device according to claim 1 in which: said clamping ring is a segmented annulus subtending an angle greater than 180°.
Claim 8
Dependent Claim
141 words
A proximity comparing device for golfers for determining relative distances of golf balls from a flagstick comprising: a C-shaped clamping ring proportioned to be releasably clamped about said flagstick and having a sufficiently low coefficient of friction to be slidable about the flagstick when clamped thereto, a string having one end secured to said clamping ring, a reel consisting of an outer ring and an inner ring disposed coaxially within said outer ring and being rotatable relative thereto, said inner ring having an internal diameter slightly larger than the diameter of a golf ball, said inner ring further having an arcuate groove extending radially inwardly from its periphery, and having an aperture extending through the inner extremity of said groove, the other end of said string being received through said aperture and being seated thereagainst to prevent withdrawal through said aperture.
Claim 9
Dependent Claim
141 words
