Camera Stands.

CAMERA STANDS, ARM STANDS.

There are several patterns of these; almost every dealer has some particular style, which, if not for beauty, for his interest, suits his purposes best. Among the assortment, I will present only two illustrations. The first, ssss1, represents one which has an advantage over many others; it is made of cast iron, and of an ornamental pattern:—A, base on castors; B, fluted hollow column, which admits the iron tube C, which has on one side a hollow tooth rack to receive a spiral thread on the inner face of wheel D; this wheel, when turned, elevates or lowers the tube C to any desired height; E, thumb wheel attached to a screw which sets against tube C, to hold it in position, F, a pinion by which the camera can be directed; G G, thumb screws to hold the two plates together when in position. It is quite heavy, stands firm and solid, and is not liable to be moved by the jar from walking over the floor. For permanently located operators these are the most desirable; but for those who are moving about from place to place, and those who wish to take views, a lighter article would be more convenient, such as one represented at ssss1. This stand is made principally of wood, and can be readily taken apart, so as to be packed in an ordinary sized trunk.
