Abstract: A putter is provided with concentrations of mass in the toe and heel portions, and the putter head is otherwise configured so that its center of gravity is approximately midway between the toe and heel of the putter head. Maximum stability within practical constraints is achieved by an especially configured hosel which slants upwardly and forwardly from proximate the heel of the putter head and positions the putter shaft so that its longitudinal axis intersects an imaginary line at a point forward of the face of the putter with the imaginary line being normal to the face of the putter and passing through the center of gravity thereof.

Abstract: A correlated set of golf clubs the heads of which each have a top ridge that extends longitudinally along the upper part of the head between the heel and toe ends thereof with enlarged mass concentrations being formed to provide upper protuberances at the heel and toe ends of the ridge. The top ridge and the upper heel and toe protuberances are especially configured to locate mass concentrations high on the heads and set back from the striking faces thereof to provide the club heads with an improved ability to resist twisting of the club heads upon laterally off-center impacts with a golf ball and to resist tilting of the club heads upon vertically off-center impacts with a golf ball.

Abstract: A wood type golf club includes a head attached to one end of a shaft. The head has a total head weight which is used in calculating a swingweight for the golf club. A face portion on a body in the club head is arranged for impacting a golf ball, and a sole plate is attached to a bottom portion of the club head. In order to resist twisting movements of the club head when impacting a golf ball at off-center points located on the body face portion, the sole plate has a majority of its weight concentrated around its perimeter by providing a cavity in an interior surface of the sole plate. The body and the sole plate each have an individual weight which is less than the total head weight. The sole plate is selected from a plurality of sole plates formed of identical material but having different weights. The weight of the selected sole plate is equal to the total head weight minus the weight of the body thereby eliminating the use of additional weighted inserts in the body.

Abstract: A golf ball has dimples formed in its outer spherical surface and arranged in a geodesic pattern defined by a plurality of imaginary grid lines which divide the outer spherical surface into an icosahedron having twenty triangular regions. Each triangular region is defined by three of the grid lines which form a spherical equilateral triangle having three sides of equal length and three medians of equal length. The dimples are arranged so that each side of the triangle radially intersects at least seven dimples, and each median of the triangle radially intersects at least six dimples. The golf ball has a total of 362 dimples including 242 dimples with a diameter of 0.140 inch and 120 dimples with a diameter of 0.150 inch.

Abstract: A putter is provided with concentrations of mass in the toe and heel portions, and the putter head is otherwise configured so that its center of gravity is approximately midway between the toe and heel of the putter head. Maximum stability within practical constraints is achieved by an especially configured hosel which extends vertically from proximate the heel of the putter head and positions the putter shaft so that its longitudinal axis intersects an imaginary line at a point forward of the face of the putter with the imaginary line being normal to the face of the putter and passing through the center of gravity thereof.

Abstract: A grip for use on the extending end of the shaft of a golf club is provided with an especially configured array of longitudinally extending grooves which are in direct opposition to the rotation of the golf club about the longitudinal axis of the golf club shaft to resist twisting of the golf club in the golfer's hand resulting from mis-hitting of a golf ball in an off center location toward the toe or heel of the golf club head. The grip may have a visual indicator by which the rotational position of the golf club when being held in a golfer's hands can be determined by visual alignement of the grip with the golfer's hands.

Abstract: A lightweight carry bag for golf clubs is provided with an automatically extensible bag stand which supports the golf bag in a propped-up position whenever the golf bag is set down during the course of playing a game of golf. The bag stand is configured to operate in the manner of a toggle mechanism with the operating force being derived from a partial longitudinal collapsing of the carry bag which occurs when the bag is set down on the ground in a vertical attitude and leaned over slightly in the direction of a partially collapsible side of the golf bag.

Abstract: A mounting device for displaying items on slatwall having grooves of T-shaped cross section formed therein. The mounting device comprises a base having a pin projecting rearwardly therefrom for extending through the open throat of the T-groove of the slatwall. The distal end of the pin has a transverse cross bar thereon which is aligned with the open throat of the T-groove and moved therethrough into the channel portion of the groove when the device is being mounted on the slatwall, and then the entire device is then rotated about its longitudinal axis to turn the cross bar into a transverse position relative to the channel. The cross bar of the mounting device is of special configuration so that a wedging action occurs when the device is rotated to move the cross bar into it's transverse position which firmly and demountably attaches the device to the slatwall. A support fixture is interchangeably carried by the base of the mounting device for supporting various articles to be displayed on the slatwall.

Abstract: A tassel for joining the ends of a draw cord of the type used for closing of a fabric bag, or optionally for mounting on the end of a pull cord of the type used for operating a lamp. The tassel includes a shell having a downwardly opening cavity with a cord end or ends receiving aperture formed through the top. A plug is demountably carried in the cavity of the shell and cord gripping elements are formed in the shell and on the plug for frictionally holding the cord end or ends in the tassel structure.

Abstract: A set of anti-scuff boots for a tile cutter comprises a pair of loops made from a soft, durable material such as leather for demountably mounting on the breaking wings of the tile cutter. The loops are connected to one another and prevented from sliding off the breaking wings by means of a strap or cord which extends over the handle of the device, preferably resting against a thumb screw in the handle which prevents the cord from slipping.

Abstract: A placer mining apparatus for intaking a slurry of water and ore bearing soils and directing the slurry to an ore separating mechanism is provided with a suction nozzle for intaking slurry and an integral puddling nozzle for selectively supplying water to produce the slurry in a dry area. A digging structure is provided at the intake end of the suction nozzle for loosening and/or burrowing into the soil.

Abstract: A tool for treating automotive ignition timing marks includes an elongated handle, a linking member and a holding fixture for holding a stick of chalk for highlighting timing marks or a cloth for cleaning the marks. The linking member is pivotably mounted to the handle, and the holding fixture is pivotably mounted to the linking member so that the elements may be positioned in a wide variety of angular orientations with respect to one another. Tightening means are provided for locking the elements in the desired positions, enabling the device to reach otherwise inaccessible areas in the engine of an automotive vehicle.
