  • Patent number: 6877364
    Abstract: A swing weight scale is presented that measures the swing weight of a golf club by measuring the torque exerted by the club about fixed balance point. The apparatus comprises an elongated torque arm pivotally mounted to a base. At one end of the torque arm a pair of rollers cradle the shaft of the golf club from underneath. At the other end of the torque arm a vertical stop provides a reference for locating the butt of the golf club shaft and provides the mounting surface for a second pair of rollers that cradle the upper surface of the shaft at the butt end. The rollers allow the golf club shaft to freely rotate about its longitudinal axis so that the golf club head will hang down freely. A torque sensor is mounted at the pivot point of the torque arm to measure the torque produced by the golf club as it is supported by the torque arm.

  • Publication number: 20040050594
    Abstract: An apparatus and technique that extend the useful weighing range of a weight scale is provided. A preferred embodiment comprises a screw and a moveable weight. A head of the screw fits into a notch on the weight scale and the location moveable weight is varied in relation to the screw head by driving the screw into or away from the center of the moveable weight via a tapped receiver of the moveable weight. In a second embodiment, a supplemental weight has a base and a movable weight that are associated and positionally adjustable along at least one linear axis. In a preferred embodiment, a threaded screw length is used to adjust the relative positions of the base and the movable weight. The supplemental weight is removably coupled with the weight scale and calibrated into an operating state, wherefrom the weighing range of the scale may be extended.

  • Patent number: 6583368
    Abstract: The invention—Ayurvedic Scale—is a machine that physically represents or models the philosophical essence of the ancient science and philosophy of Ayurveda in the form of a tri-armed scale. The Ayurvedic Scale's primary function is to assist users in determining and visually representing their current spiritual state as well as their underlying Ayurvedic body type, which are both helpful in evaluating immediate choices using Ayurvedic philosophy. It also serves to act as a visual model in helping users to more clearly understand the complexities of Ayurveda, to provide a physical reminder of Ayurveda's suggested foci in the user's life, and to act as a decorative model, which reflects the owner's interest in Ayurveda. The invention is meant to embody two of Ayurveda's core foci—simplicity and balance.

  • Patent number: 6509534
    Abstract: A lightweight, portable scale, including a balance beam pivotally positioned on a fulcrum, contained in a tear-drop shaped carrying case. The portable scale has a load pan on one end of the balance beam and a graduated scale, configured to accommodate sliding weight members, extending toward the opposite end of the balance beam. The fulcrum is positioned between the load pan and the graduated scale. To establish equilibrium, the balance beam includes a stationary counter-weight attached on the load pan side of the fulcrum, which balances the empty load pan against the sliding weight members located at a zero position on the graduated scale. The carrying case has a top portion hingedly attached to a bottom portion, which functions as the base of the portable scale and has sidewalls shorter than the fulcrum, preventing interference by the side walls during the weighing process.

  • Patent number: 6284987
    Abstract: A weighing scale detects and indicates changes in a small weight that is embedded within a much larger residual weight. The scale device has a base and a top weighing pan above it, with a linkage supported between the base and the top pan. A counterbalance weight lever is supported on a pivot member, and has one end connected to the linkage, and a counterbalance weight on the other end. An adjustable tensioning spring provides a balancing force for the counterbalance weight lever within the weight range of the critical weight. A potentiometer of other detecting device can provide an electrical signal to an alarm device to warn the consumer that the weight of a consumable quantity has dropped into the critical weight range.

  • Patent number: 6268573
    Abstract: A portable postal scale for determining whether the weight of a letter exceeds the maximum for a given amount of postage, for example, one ounce. The scale comprises an elongated beam having a letter holder, a fulcrum, a leveling assembly and a preloaded portion and a wedge shaped piece. The letter holder comprises two upward facing arms forming a narrow slot for holding the letter to be weighed in an upright position. The leveling assembly, which allows the scale to be used on an unlevel surface, comprises a leveling bubble with scribe lines. The portion of the beam from the fulcrum to the end opposite the letter holder is the preloaded portion that has sufficient weight to balance the beam when a letter of predetermined weight is placed in the letter holding slot. In use, the end of the beam opposite the letter holder is placed on top of the wedge shaped piece, which is moved forward or backward until the leveling assembly is level.
