GOLF CLUB HEAD WITH MOVABLE WEIGHT
Abstract
A golf club head incorporating a hollow interior with a movable
weight supported on a mounting rod which can be oriented in
different angular positions to counteract the tendency of a golfer
to hook or slice the ball and to increase the distance which the
ball is driven due to the additional forces exerted on the ball by
the movable weight. The movable weight is centered on the mounting
rod by spring devices and the overall shape and configuration of
the golf club head is not changed.

Claims
What I claim as new is as follows:
1. A golf club head comprising a body having a substantially flat
golf ball impact surface on the leading surface thereof, a bore in
said body having a longitudinal axis extending from said impact
surface area to the rear of the club head, a mounting rod disposed
in said bore generally along said axis, a weight means mounting
said weight on said rod for slidable movement in response to the
swing of the golf club, and means for adjustably supporting the
mounting rod in said bore so that the longitudinal axis thereof may
be angularly varied in relation to the longitudinal axis of the
bore so that movement of the golf club head in a path to cause the
golf ball to deviate from a straight line flight path will be
compensated for by the shifting of the movable weight.
2. The structure as defined in claim 1 wherein said means mounting
the rod includes opposed recesses in the opposite ends of said
bore, one end of said bore having a plurality of spaced recesses
for selectively receiving the end of a mounting rod to orient the
rod in a selected angular relation to the bore.
3. The structure as defined in claim 2 wherein the plurality of
recesses are oriented in the rear of said bore, an insert plate
mounted on the rear of the club body and forming a closure for the
rear end of the bore, said insert plate having a projecting boss
extending into the bore and provided with a concave inwardly facing
surface, said recesses being disposed in said concave surfaces and
being horizontally disposed for enabling the mounting rod to be
disposed in different angular positions in a horizontal plane to
counteract the out-to-in swing which causes a slice and the
in-to-out swing which causes a hook of a driven golf ball.
4. The structure as defined in claim 3 wherein said golf ball
impact face includes an insert plate forming a closure for the
forward end of the bore, said insert plate including a boss on the
inner surface thereof extending into the bore and including a
recess receiving the forward end of the mounting rod.
5. The structure as defined in claim 4 wherein said mounting rod
includes a reduced end at each end thereof for reception in the
recesses.
6. The structure as defined in claim 5 wherein said bore, mounting
rod and weight are of cylindrical construction, and a coil spring
interposed between each side of the weight and the insert plates to
retain the weight in resiliently spaced relationship to the plates
to enable movement of the weight during acceleration and
deceleration of the golf club head.
Description
The present invention generally relates to a golf club head and
more particularly to a golf club head having a movable weight
incorporated therein with the angular direction of movement of the
weight in relation to the golf club head being adjustable so that
if the golfer has a tendency to hook the ball, slide the ball or
hit a straight ball, the adjustable weight can be preset for the
particular requirements of each individual golfer.
One of the many problems encountered by golfers is the tendency to
engage the face of the club head with the ball in a manner that
causes the ball to deviate from the desired path of flight.
Generally, a golfer will have a tendency to slide the ball, hook
the ball or drive the ball straight and will consistently drive the
ball in the same manner. That is, if a person slices the ball, he
usually will consistently slide the ball on each drive off the tee
or if he has a tendency to hook the ball, he usually will hook the
ball when he drives off each tee. While this tendency can be
compensated for to a degree by varying the position of a golfer in
relation to the golf ball and desired flight path, this does not
effectively serve the problem inasmuch as substantial distance is
lost when the ball is either sliced or hooked.
Accordingly, it is an object of the present invention to construct
a golf club head with a movable weight therein which will
counteract the tendency to slice or hook the golf ball and increase
the distance where the golf ball is driven as well as increase the
degree of accuracy of the flightpath.
Another object of the invention is to provide a golf club head
having a longitudinally elongated mounting rod slidably supporting
a weight in the hollow interior of the golf club with the angular
position of the rod in relation to the club head face being
adjustable so that the characteristics of the golf club head can be
preset to adapt the golf club for each individual golfer depending
upon the tendency of that golfer to either slice, hook or drive the
ball straight.
A further important object of the present invention is to provide a
golf club head in accordance with the preceding objects which is
simple in construction, easy to preset, relatively inexpensive to
manufacture and effective for correcting the tendency to slice or
hook and also impart additional impact forces to the golf ball.
These together with other objects and advantages which will become
subsequently apparent reside in the details of construction and
operation as more fully hereinafter described and claimed,
reference being had to the accompanying drawings forming a part
hereof, wherein like numerals refer to like parts throughout, and
in which:
FIG. 1 is a plan sectional view of a golf club head with the
present invention incorporated therein.
FIG. 2 is a transverse, sectional view taken substantially upon a
plane passing along section line 2-2 of FIG. 1 illustrating the
structural relationship of the movable weight, the mounting rod,
coil spring and hollow interior of the golf club head.
FIG. 3 is an exploded group perspective view of the golf club head
of the present invention.
Referring now specifically to the drawings, the numeral 10
generally designates the golf club head of the present invention
which may be any of the usual wood clubs employed to drive the golf
ball from a tee or from the fairway with the club head being of
conventional shape and configuration and constructed of
conventional materials such as laminated wood or the like with the
club head including a body 12 having a face 14 oriented thereon in
a conventional manner and an upwardly extending shank 16 to which
the usual club handle is attached.
The club head body 12 includes a longitudinal passage or bore 18
extending from front to rear thereof with the bore 18 being
generally cylindrical in configuration and generally having a
central axis coincident with the center of the club face 14. The
club face 14 is provided with an insert plate 20 having upwardly
converging side edges received in a correspondingly shaped recess
22 in the club face 14. Countersunk screw-threaded fasteners 24 are
provided for securing the insert plate 20 in position with this
structure being that found in presently available wood clubs.
The inner surface of the insert plate 20 is provided with a
projecting boss 26 of cylindrical construction having a centrally
disposed recess 28 formed therein for receiving the reduced end 30
of an elongated cylindrical mounting rod 32 with the recess 28
being such that the mounting rod 32 may be angularly disposed in
relation to the surface of the boss 26.
The trailing or rear end of the bore 18 is closed with an insert
plate 34 having an external curvature conforming with the curvature
of the trailing surface of the club head. The insert plate 24 is
secured in place by screw-threaded fasteners similar to the
threaded fasteners 24 and the inner surface thereof is provided
with a projecting boss 36 having a concave inner surface 38 and
three horizontally recesses 40 therein for receiving a reduced end
42 on the mounting rod 32 which is opposite from the reduced end
30. Thus, the rod 32 may be positioned with the longitudinal axis
thereof parallel with the front-to-rear axis of the bore 18 or
disposed in angular relation thereto with the three positions of
the axis of the rod 32 being illustrated in FIG. 1 and designated
as "hook," "straight" and "slice."
Slidably mounted on the rod 32 is a cylindrical weight 44 having a
central bore 46 slightly larger than the rod 32 to enable free
sliding movement thereon. A relatively short compression coil
spring 48 encircles the rod 32 between the sliding weight 44 and
the boss 26 on the insert plate 20 and the relatively longer
compression coil spring 50 encircles the rod 32 and is interposed
between the weight 44 and the concave surface 38 of the insert
plate 34. With this construction, the springs will retain the
weight 44 in a normal position spaced away from both the insert
plate 20 and the insert plate 34 but yet enable relative movement
of the weight 44 as the springs 48 and 50 are compressed during
acceleration of the club head and deceleration thereof.
If the rod 32 and the weight have been reset along the "slice" line
in FIG. 1, upon impact of the club head face with the golf ball,
the weight moves outwardly in an angular path along the rod 32 thus
moving outwardly of the club head and counteracting the out-to-in
swing which originally caused the slice. Correspondingly, when the
weight and mounting rod have been oriented along the "hook" line in
FIG. 1, upon impact with the golf ball, the weight moves along the
rod 32 toward the inside of the club head thus counteracting the
in-to-out swing which causes the hook. When the club head face
engages the ball in a straight line manner and the rod 32 has been
oriented in the center position indicated as "straight" in FIG. 1,
the weight moves forward along the rod 32 thus giving the golf ball
added momentum and the golf club added followthrough.
The angular position of the rod 32 may be preset at the factory
upon custom order of an individual golfer or the retail
establishment or the customer himself may adjust or set the angle
of the rod 32 to solve his particular tendencies.
By actually shifting the weight to counteract the errors in the
swing of the club head which causes the hook or slice, the golfer
will actually change his swing by following the forces of the
weight thus enabling the golfer to more properly swing the club
head in a proper path even when a club is being used that does not
have the movable weight of the present invention incorporated
therein.
The foregoing is considered as illustrative only of the principles
of the invention. Further, since numerous modifications and changes
will readily occur to those skilled in the art, it is not desired
to limit the invention to the exact construction and operation
shown and described, and accordingly all suitable modifications and
equivalents may be resorted to, falling within the scope of the
invention as claimed.
