Claims (1)

The photographic chambers, carried on a belt, hang when they can be held in a free-floating manner on the belt, vertically. Carried in front of the chest but hanging according to the diagonal pull of the belt on the chamber. The invention provides a means that allows the chamber to be perpendicular in any inclined position of the belt ascertain. For this purpose is the ίο appropriately hinged belts attached to the upper end of the chamber housing can be locked in any desired angular position relative to the chamber.
An embodiment of the invention to be viewed as an example is shown schematically in the drawing on a scroll chamber with mirror finder in Fig. 1 in side view, in Fig. 2 in plan and in Fig. 3 in partial side view with the chamber half open. According to this, the strap ends α are suspended from pin c near the upper edge of the chamber b so that they can assume the two positions shown (and also any desired intermediate position) relative to the chamber. In position I, which corresponds to holding the belt with the hand, the chamber hangs vertically. But it also hangs vertically at strap position II, which corresponds to hanging in front of the chest. The belt ends are passed behind clamping rails d of the appropriate length, through which they can be locked in any position. In the example shown, these clamping rails form leaf springs which are attached with such tension that they press the belt α in every position against the chamber wall. The rails d can also be provided with notches β , as indicated in FIG. 4, in which the belt is locked in its end positions, as it were. If the notch edges f are beveled, all that is needed to move the belt from one notch to the other is to pull the belt itself firmly. The clamping rails d offer the advantage that they can be removed for the suspension of the chamber housing cover g, which when the chamber is used for enlargement or the like must, can be made usable. In the example shown, the eyelet plates d are lengthened beyond their fastening points h for this purpose and provided with holes in which pins i of the cover g find their bearings. This lid swivel joint is, as FIG. 3 indicates, made easily detachable in that one spring plate d is designed to be swivelable somewhat, in such a way that the lid g with its pin i can be unhooked as shown in FIG. This cover releasability can also be achieved in other ways, e.g. B. by using open bearings on the fixed rails d in this case, from which the cover pin i can only be lifted with a certain cover position. The rails d, and thus of course the lid joints, can also be retrofitted to existing chambers without any particular effort and expense. It is advantageous to place the fastening pin c as high as drawn (or at least similar), because then the belt α can be positioned at an angle to the chamber within very wide limits with relatively short rails d.
