As you see, the essential frame consists of six slats, theuprights being hinged to the horizontals so that they may befolded on them. The side slats are retained in position by meansof slotted ends, which are perforated to admit pins. Theuprights have holes drilled in them for the pins, the distancebetween the centers of two adjacent holes being exactly one-half inch. If the first hole be made at the proper distance fromthe top horizontal slat, the spaces, when the slats are adjusted,will be found to fit the plates, whatever be their size, and retainthem without their falling through. The frame is braced by American Quarterly of Roentgenology.
