. GOLF PRACTICE SET Filed July 2, 1928 INVENTORS 72g ATTORNEY Patented. Oct. 1, 1929 GOLF PRACTICE snr Application filed July 2, 1928; Serial No. 289,769.
This invention relates to new and useful improvements in golf practice sets.
It is one of the principal objects of our invention to provide for those persons who desire to practice the game of golf, a set or unit comprising a pin to which a golf ball is revolvably and resiliently secured by a spring and chain mechanism. The pin is adapted to be fixedly secured in the ground so that when the ball is hit, its flight will be limited by the length of the chain.
If the ball is hit by a straight shot of the club, it will spin around the pin several times; if it is sliced it will go about half way around the pin; and if it is topped, it will travel about one quarter of the distance around the pin.
It is thus possible for one to determine the proficiency of his drives by the distance the ball travels around the pin after it has been hit by the club employed.
Other important and incidental objects will be brought out in the following specification and particularly set forth in the subjoined claims.
Referring to the accompanying drawings for a detailed description of our invention, Figure 1 is a side view of the golf practice unit, showing it ready for use. Figure 2 is an enlarged side view of said practice set.
Figure 3 is a sectional view taken through the yoke and the hook connection of said practice set. And Figure 4 is a cross sectional View taken through the helical spring and guide therefor.
Referring to the accompanying drawings for a detailed description of our invention, the numeral 1 designates a holding member such as the pin 1 which is pointed at its lower end so that it may be easily driven into the ground.
At its upper end the pin 1 is formed with an annular groove 2, to receive the round portion of a yoke 3. (See Figures 2 and 3.)
The yoke 3 has two straight ends formed with registering slots to receive the hook end 4 of a rod 5 having a flanged rear end 6.
Loosely fitted on the front end of the rod 5 is the cylindrical head portion 7 of a wire frame 8 which projects beyond the pin 5.
Surrounding the rod 5 between its flange 6 and the head 7 of the frame 8, is a helical spring 9 against the tension of which the frame is adapted to be drawn outwardly along the rod.
The outer end of the wire frame 8 is formed in V shape to receive a ring 10. To the latter one end of a chain 11 isse'cured. The other end of this chain is connectedto the hook end of aT shaped rod 12 embedded within a golf ball 13. '7
When it is desired to use the practice set just described, the pin 1 is driven vertically into the ground as shown in Figure 1. The ball 13 may then be placed upon a tee 1 1 21 5 desired distance from the pin 1 within the length of the chain 11. When the ball 18 is then hit by a club such as the driver 14*, its normal flight will be limited by the chain. However, if the ball is so driven that it would follow a straight course, the ball will spin around the pin 1 several times. This is made possible by the fact that the yoke 3 is free to turn around the grooved portion 2 of the pin.
If the ball is sliced, it will go approximately half-way around the pin; and when it is" topped, it will make but a quarter turn about the pin.
Thus it is possible, with our set, to test a golfers skill without the inconvenience of ,s0 going or sending after the ball when it is hit, or running the risk of losing it.
The ball will also yield with a certain amount of springiness to the one hitting it, since the wire frame 8, to which the chain 11, is secured, moves outwardly along the rod 5 against the tension of the spring 9.
It is thus seen that our practice set constitutes a simple, resilient and accurate means of testing a golfers skill without risk of losing oo the ball or the inconvenience of going or sending after it each time it is hit.
We do not wish to be limited to the details of construction and arrangement herein shown and described, and any changes 013 modifications may be made therein within the scope of the subjoined claims.
Having described our invention, we claim 1. In a unit of the type described, a pin, an annular element secured to said pin &I1(1 -,l00
free to revolve around it, a rod pivotally secured to the annular element, a stop element on the outer end of said rod, a wire frame loosely fitted at its front end on said rod for a free movement along it, a helical spring secured to said rod between said stop element and the head of the frame, a chain secured to the outer end of the frame, and a golf ball secured to the chain.
2. In a unit of the type described, a pin formed with an annular groove, a yoke secured in said groove and free to revolve around the pin, a rod having a hook end secured to said yoke, a stop element on the other end of said rod, a wire frame loosely fitted at its front end on said rod for a free movement along it, a helical spring secured to said rod between said stop element and the head of the frame, a chain secured to the outer end of the frame, and a golf ball secured to said chain.
In testimony whereof we have hereunto set our hands this 29th day of June, 1928.
