A carriage holder for support of an apparatus includes identical upper and lower support plates having on their outer edge a number of indentations corresponding to the number of apparatus to be supported, said indentations providing aligned radial horizontal grasping surfaces on one side of said apparatus. The carriage holder also includes a series of vertical spring pivot pins joining said upper and lower support plates, adjacent to each said indentation, each such pin bearing a torsion spring loaded retractable clamp member to provide grasping surfaces in retracted position opposite to the grasping surfaces of said indentations. The carriage holder also includes an unobstructed aperture in each of said aligned support plates for mounting said carriage holder on a shaft. The carriage holder further includes a locking mechanism to hold said carriage in a fixed position on the shaft.
