Abstract: Bicycle handlebars and handlebar attachments to provide multiple hand grips when a rider assumes different postures. The handlebars and attachments define three auxiliary hand grip positions. A first auxiliary gripping portion extends forward from a conventional handlebar parallel to a vertical, central common plane and inclined upwardly. A second auxiliary gripping portion parallels the conventional handlebars. A third auxiliary gripping portion parallels the common plane, lies below the handlebars and parallels the first auxiliary portion.

Abstract: A dispenser includes a hollow dispensing tube which reciprocates within a container and which incrementally moves a piston downwardly for forcing paste upwardly through a lower inlet end of the tube and outwardly through a nozzle located at the opposite end of the tube. To facilitate the operation of the dispensing tube, an actuator is employed which is pivotally mounted at one end to a head mounted to the body of the dispenser with the pivot connection located on one side of and adjacent to the dispensing tube. A cam and cam follower extend between the actuator and the dispensing tube for initially providing an increased downwardly applied force to the dispensing tube and subsequently decreasing the force during a dispensing stroke of the actuating lever.
