Abstract
Abstract Apparatus for improving a golfer's putting stroke including a pair of parallel, spring tensioned flexible cables mounted in spaced relation above a horizontal platform constituting a putting surface and on opposite sides of the resting site of the golf ball. The head of the putter is provided with grooves that slidingly receive the cables, or a guide attachment is detachably secured to the putter head that has guided sliding engagement with the cables.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
167 words
A training aid for golfers for improving their putting stroke by urging linearity of movement of the putter head in the vertical plane as it moves to contact a golf ball, said aid comprising a green simulating means defining a horizontal putting surface, and the provision of coacting first and second guide means respectively adapted to be carried by a putter head and mounted on the green simulating means, said second guide means including an elongated and flexible guide element of substantially cylindrical transverse section, spaced support means secured to the green simulating means for supporting the opposite ends of said element with the latter extending freely therebetween in spaced relation above the putting surface, resilient means for yieldingly maintaining said element under tension in its extent between the support means, said element being slidingly engageable by the first guide means and operative during such sliding engagement to yieldingly oppose departure of the first guide means from a path having a straight projection on a horizontal plane.
Claim 2
Dependent Claim
167 words
A training aid for golfers for improving their putting stroke by urging linearity of movement of the putter head in the vertical plane as it moves to contact a golf ball, said aid comprising a green simulating means defining a horizontal putting surface, and the provision of coacting first and second guide means respectively adapted to be carried by a putter head and mounted on the green simulating means, said second guide means including an elongated and flexible guide element of substantially cylindrical transverse section, spaced support means secured to the green simulating means for supporting the opposite ends of said element with the latter extending freely therebetween in spaced relation above the putting surface, resilient means for yieldingly maintaining said element under tension in its extent between the support means, said element being slidingly engageable by the first guide means and operative during such sliding engagement to yieldingly oppose departure of the first guide means from a path having a straight projection on a horizontal plane.
Claim 3
Dependent Claim
33 words
The combination of claim 1, wherein said second guide means also, during sliding engagement by the first guide means, yieldingly opposes downward movement of the first guide means relative to a horizontal plane.
Claim 4
Dependent Claim
36 words
The combination of claim 1, wherein the elongated element has its opposite ends connected to the spaced support means, with the connection of the element to the support means including a spring constituting said resilient means.
Claim 5
Dependent Claim
46 words
The combination of claim 1, including a putter head, with said first guide means including said putter head having a groove in its lower edge when disposed in its position of use for slidingly and guidingly receiving the elongated element of the second guide means therein.
Claim 6
Dependent Claim
124 words
A training aid for golfers comprising a green simulating means presenting a horizontal putting surface, a guide means including a pair of elongated and flexible guide elements horizontally disposed in horizontally spaced parallelism to each other and spaced above the putting surface, resilient means secured to the green simulating means and connected to the extremities of the elements for supporting and maintaining the latter under tension whereby the elements yieldingly oppose lateral displacement vertically and horizontally from a normal position of repose to which position the elements are restored on removal of any displacing force, and said guide means also including a coacting guide means slidably and guidingly engageable with the guide elements for urging a putter head to travel a preselected putting stroke.
Claim 7
Dependent Claim
124 words
A training aid for golfers comprising a green simulating means presenting a horizontal putting surface, a guide means including a pair of elongated and flexible guide elements horizontally disposed in horizontally spaced parallelism to each other and spaced above the putting surface, resilient means secured to the green simulating means and connected to the extremities of the elements for supporting and maintaining the latter under tension whereby the elements yieldingly oppose lateral displacement vertically and horizontally from a normal position of repose to which position the elements are restored on removal of any displacing force, and said guide means also including a coacting guide means slidably and guidingly engageable with the guide elements for urging a putter head to travel a preselected putting stroke.
Claim 8
Dependent Claim
40 words
The combination of claim 6, including a putter head, with said coacting guide means comprising the putter head having a pair of grooves in its lower edge when disposed in its position of use slidably receiving the elongated guide elements.
Claim 9
Dependent Claim
69 words
The combination of claim 6, including means for detachably securing the coacting guide means to a putter head and wherein said coacting guide means is a U-shaped member that includes an elongated web connecting depending flanges that have a spacing about the same as that of the elongated elements for receiving the latter therebetween, and wherein said detachably securing means includes an element adapted to embrace a putter head.
Claim 10
Dependent Claim
44 words
The combination of claim 5, wherein said resilient means includes in association with each of said elongated elements a pair of upstanding posts secured to the green simulating means, with coiled tension springs connecting the opposite extremities of the elongated element to the posts.
Claim 11
Dependent Claim
20 words
The combination of claim 8, wherein the posts are detachably secured to the green simulating means by threaded fastening means.
Claim 12
Dependent Claim
55 words
The combination of claim 8, wherein the posts are L-shaped and include a vertical leg having an integral horizontal leg at its top, each of said coiled tension springs having one end embracing an extremity of an elongated element and its other end embracing an extremity of the horizontal leg of one of the posts.
