Trueball Tripod Head for Studio
Professional Cameras Is Invented
A new tripod head for professional motion picture cameras, known as the "Hoefner Trueball Tripod Head, Model B," has been placed on the market by Fred Hoefner, wellknown Hollywood precision mechanic
The new head is a companion creation to Hoefner's "Model A," which, announced in the June issue of this publication, was designed for amateur cameras, among the users of which it has found a wide demand.
Operating Principle
As with the amateur type, the Model B works on the true-ball principle.
"This is the only way," Hoefner states, "that more than one required motion can be made to move simultaneous, making the motion continuous and the tension equally maintained, for the following of a moving object — as there is only one side or surface to a ball.
"Among the other features are: By turning a hand screw, the pan is locked and the tilt moved through a ninety-degree arc; and, by reversing the action of this screw, the tilt is locked and the pan action released. Also, the whole head may be instantly locked, making it more rigid. The drag tension may be adjusted to suit the operator. The operating handle is removable and telescopic. It is adjustable to any angle and length required."
