  • Publication number: 20240123307
    Abstract: A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

  • Patent number: 5950807
    Abstract: A wire belt having increased belt strength includes a plurality of wire links having alternating wide linking portions and narrow linking portions interlocked with respective linking portions of an adjacent wire link. The assembly of the wire belt includes interlocking the wire links, for example, by placing the wide linking portions into an engagement with wide linking portions of an adjacent wire link. The width of the wide linking portions is about equal to the minimum width that will allow the wire link to be interlocked with an adjacent wire link without bending the wire link in excess of the yield strength of the wire link. The width of the narrow linking portions is less than the width of the wide linking portions, and preferably, dimensioned to receive a sprocket for driving the wire belt. The wire links preferably have an undulating shape and include first and second end loops that interlock with adjacent wire links.

  • Patent number: 5894871
    Abstract: A mobile dispensing apparatus capable of onsite bagging of fluent solid materials such as sand. The apparatus includes a hopper supported on wheels and having a trailer hitch. Three augers convey fluent material to three chutes. Each chute has a clamp for supporting a bag being filled. The apparatus has an on-board engine and a transmission selectively driving each auger. A pedal at each chute operates its respective clamp and connects its respective auger to the transmission by an electric clutch. The hopper has side doors and rear doors. A ramp can be removably attached at the rear door of the hopper. An open grate forms a floor within the hopper. Shelves are disposed within the hopper.
