Abstract
Abstract A golf putting stroke training device is provided comprising a carriage slideable along a rectilinear guide member supported above ground in a horizontal position, a putter being rigidly attachable to the carriage. Optional locking pivot means are provided for varying and fixing the angle made by the putter shaft with the ground. A locating apparatus is also provided which by repeated placement of an inclined guide and by rolling a ball down the same, permits the training device to be properly positioned with respect to the hole by abutment with a spacer member of the said apparatus.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
157 words
A device for use in striking a golf ball with a putter, and in training a player to develop a correct stroke, which device comprises: (a) a ground-engaging support member; (b) a guide member supportable by the support member and having, when so supported a horizontally disposed rectilinear upper edge; (c) a guided carriage adapted to rest in contact with said upper edge, and free to move to-and-fro along said guide member when vertically lifted clear of said resting contact; (d) means preventing movement of the guided carriage transversely of said upper edge, other than the vertical lift movement; (e) means for rigidly attaching the shaft of a standard golf putter to the carriage with the putter head in ground contact; and (f) means associated with said means for attaching the shaft to the carriage for selecting the angle of elevation of said shaft to the horizontal so that the putter sole is flat upon the ground.
