These brackets can be fixed at any height on the uprights e by the device shown in Fig. 4. Toothed metal plates l are fixed to the front of each of the back frame uprights e. These plates have notches or holes m on their inner edges. Sliding plates n embrace each of the uprights e and carry the hinged brackets o. Each of the plates n is provided with a spring t having a stud x adapted to engage the holes m and so fix the bracket o in position.
