Abstract

Abstract The inertia attachment includes an arm on which is a weight adjustable longitudinally of the arm and a clamp adapted to attach the arm to the shaft of a golf club which requires followthrough when swung; the weight has tail fins and is shaped to be directional in the direction into which the shaft is swung and is registerable with the head of the golf club or the like; the arm is pivoted on the clamp so as to be adjustable from an out of the way position parallel with the shaft toward and above the club head. In one embodiment, the weight may include a rotatable propeller mounted in a recess between the tail fins. In another embodiment, the weight is shiftable along a shaft and compresses a spring as the weight moves rearwardly. The weight includes a passage through which the arm extends, and the weight may be secured in various positions along the length of the arm by the provision of a spring clip located in the passage. The spring clip is adapted to selectively engage grooves provided along the length of the arm.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 114 words
In combination, a game club and an inertia device for followthrough practice of said game club, said device comprising, an inertia body, and means to attach said inertia body to said club so as to hold said inertia body to be moved on the same arc As said club is swung thereby to exert momentum for continued movement of said club, said inertia body being approximately spherical, a frusto-conical leading extension on said body, tail fins extended from said body axially oppositely to said leading extension, and means to adjustably connect said inertia body to said attaching means in a position wherein said leading extension is in the direction of movement of said club.
Claim 2
Dependent Claim 114 words
In combination, a game club and an inertia device for followthrough practice of said game club, said device comprising, an inertia body, and means to attach said inertia body to said club so as to hold said inertia body to be moved on the same arc As said club is swung thereby to exert momentum for continued movement of said club, said inertia body being approximately spherical, a frusto-conical leading extension on said body, tail fins extended from said body axially oppositely to said leading extension, and means to adjustably connect said inertia body to said attaching means in a position wherein said leading extension is in the direction of movement of said club.
Claim 3
Dependent Claim 25 words
The combination specified in claim 1, and said club having a striking head, and a shaft extended from the striking head for swinging said head.
Claim 4
Dependent Claim 43 words
The combination specified in claim 1, and said club having a shank and a head, and a striking face on said head for striking a ball, said leading extension being at right angles to the plane of the striking face of the club.
Claim 5
Dependent Claim 25 words
The combination specified in claim 3, and said adjustable connecting means including an arm, and means to adjustably support said inertia body on said arm.
Claim 6
Dependent Claim 46 words
The combination specified in claim 4, and said attaching means including, a clamp adapted to be secured to the shaft of the golf club, said arm being adjustable on said clamp into positions parallel with the shaft and into operative positions parallel with said club head.
Claim 7
Dependent Claim 30 words
The combination specified in claim 4, and said arm being flat, and being in a plane approximately at right angles to the plane of said striking face of said club.
Claim 8
Dependent Claim 52 words
The combination specified in claim 6, and said means to adjustably support said inertia body on said arm including, a plurality of grooves on said flat arm, said body having a passage therethrough slideable on said flat arm, and a spring clip in said passage resiliently and selectively engageable with said grooves.
Claim 9
Dependent Claim 38 words
The combination specified in claim 4, and said tail fins providing an inward recess, and a freely rotatable propeller mounted in said recess so as to be rotated by the airflow during the back stroke of said article.
