25,128. Behrmann, J. H., and Sander, H. Nov. 15. Hot-beds.-Relates to means for supporting the lights of hot-beds either for purposes of ventilation or to enable access to be obtained to the bed. The lights are not attached directly to the frame, but are fitted with wire guides 7, 8 and a flat spring 10 carrying a pin adapted to engage one of a series of holes in a flat support 4, secured by a thumb-nut 2 on a screw fastened to the body of the frame. The light may be turned up on its edge, as shown at the left-hand side of Fig. 1, to afford access to the bed, or may be raised to any extent at its upper end, as shown at the righthand side of Fig. 1, for purposes of ventilation.
