Abstract
Abstract A golf putting device having an inclined ramp and an abutting normally plane surface having a hole for receiving a golf ball stroked toward the hole and traversing the ramp and plane surface. Lifting rods are disposed for cooperating with the normally plane surface for distorting the normally plane surface. In a typical example, the mat covering the plane surface is slightly elevated at one location by one of the lifting rods disposed underneath the mat. A control handle and slide rod are coupled to the lifting rods to control the amount of elevation as well as the location in the horizontal plane.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
109 words
A golf practice putting device comprising: a support for providing an inclined ramp portion and an abutting normally level portion; a mat covering said normally level portion; an aperture disposed in said mat and support at said normally level portion for receiving therein a golf ball rolling over said normally level portion; means for engaging the underside of said mat coupled to said support for elevating a localized portion of said mat at said normally level portion for distorting said mat from its normally level position, and control means, accessible via said aperture coupled to said means for engaging said mat for controlling the elevation of said localized portion.
Claim 2
Dependent Claim
109 words
A golf practice putting device comprising: a support for providing an inclined ramp portion and an abutting normally level portion; a mat covering said normally level portion; an aperture disposed in said mat and support at said normally level portion for receiving therein a golf ball rolling over said normally level portion; means for engaging the underside of said mat coupled to said support for elevating a localized portion of said mat at said normally level portion for distorting said mat from its normally level position, and control means, accessible via said aperture coupled to said means for engaging said mat for controlling the elevation of said localized portion.
Claim 3
Dependent Claim
115 words
A golf practice putting device comprising: a support for providing an inclined ramp portion and an abutting normally level portion; a mat covering said normally level portion; an aperture disposed in said mat and support at said normally level portion for receiving therein a golf ball rolling over said normally level portion; a movably mounted lifting rod adapted to engage the underside of said mat coupled to said support for elevating a localized portion of said mat at said mormally level portion for distorting said mat from its normally level position, and control means, accessible via said aperture, coupled to said lifting rod for controlling the elevation of said lifting rod relative to said support.
Claim 4
Dependent Claim
115 words
A golf practice putting device comprising: a support for providing an inclined ramp portion and an abutting normally level portion; a mat covering said normally level portion; an aperture disposed in said mat and support at said normally level portion for receiving therein a golf ball rolling over said normally level portion; a movably mounted lifting rod adapted to engage the underside of said mat coupled to said support for elevating a localized portion of said mat at said mormally level portion for distorting said mat from its normally level position, and control means, accessible via said aperture, coupled to said lifting rod for controlling the elevation of said lifting rod relative to said support.
Claim 5
Dependent Claim
45 words
A golf practice putting device as set forth in claim 2, said lifting rod being pivotally mounted with one end to a slide rod, and said control means coupled to said slide rod for controlling the elevation of the other end of said lifting rod.
Claim 6
Dependent Claim
33 words
A golf practice putting device as set forth in claim 2, and means disposed on said support for causing said lifting rod to be rotatable about a substantially vertical axis through said aperture.
Claim 7
Dependent Claim
133 words
A golf practice putting device comprising: a support for providing an inclined ramp portion and an abutting normally level portion; a mat covering said normally level portion; an aperture disposed in said mat and support at said normally level portion for receiving therein a golf ball rolling over said normally level portion; at least one pivotally mounted lifting rod coupled to said support for elevating a localized portion of said mat at said normally level portion for distorting said mat from its normally level position, and control means including a pivotally mounted lever, accessible via said aperture, coupled to one end of said rod lifting rod for causing pivotal motion of said rod responsive to the operation of said lever, whereby to control the elevation of said lifting rod relative to said support.
Claim 8
Dependent Claim
133 words
A golf practice putting device comprising: a support for providing an inclined ramp portion and an abutting normally level portion; a mat covering said normally level portion; an aperture disposed in said mat and support at said normally level portion for receiving therein a golf ball rolling over said normally level portion; at least one pivotally mounted lifting rod coupled to said support for elevating a localized portion of said mat at said normally level portion for distorting said mat from its normally level position, and control means including a pivotally mounted lever, accessible via said aperture, coupled to one end of said rod lifting rod for causing pivotal motion of said rod responsive to the operation of said lever, whereby to control the elevation of said lifting rod relative to said support.
Claim 9
Dependent Claim
24 words
A golf practice putting device as set forth in claim 5, the other end of said lifting rod provided with a substantially spherical member.
Claim 10
Dependent Claim
31 words
A golf practice putting device as set forth in claim 5, and means operative between said support and said mat for urging an elevated portion of said mat toward said support.
