FIG. 22. THE ACME TOP.

THE BALANCE STAND.

This style comprises a greater variety of forms than all the others combined, it requiring the least exertion to move the box up or down. The weight of the camera box when placed on the stand top is counterbalanced by weights which rest upon a shelf attached to cords, which pass over pulleys and downwards, to be fastened to uprights which support the top; when properly balanced it requires only a touch of the hand to raise the box or to lower it.

THE BOWDISH STAND.

FIG. 23.

The most popular form of this stand is the Bowdish. See cut 23. The description will be rendered quite intelligible by observing the weights which are in the centre, between the three legs, and the cords which pass over the pulleys to the three supports of the top. From the peculiar construction of this stand it has the most simple p120 means of adjustment; it is raised or lowered by touch, and a binding screw serves to keep it immovably in position.
