suspension in certain cases. 3. Rope, weights (Figure 3), and pulley (Figure 4). The pulley and pulley clamp shown in Figure 4 are adaptations made by our engineering department. 4. Bar for the foot of the bed, with U screws and wing nuts. The engineering department has devised the apparatus shown in Figure 5 for use on Gatch beds. The cost is small. First there is the long bar of cold rolled steel one-fourth by three-fourths inches cut the width of the beds, in this case thirty-one inches long. This bar is covered with felt and has four five-sixteenths inch holes drilled in it, one on each side of the two spindles :: ;ai-i.?:i;l~cl::?:,?:? :' :? .J "'` ii'ii~i'i.:i'.: ??? ::e\:-us~n~i?e~arPr\~;?? .. ?.?. ..:;:::? :. :-::r~s?:??-?;:;:*-3??r~:aJ%?~*re~*?Lp~
