Fig. 151.—A special trochoscope (Johnston and Grier)having one pair of legs, situated at themiddle, the end of the top being fastenedto the wall. The tube box moves on apair of tracks parallel with the length ofthe table. A subframe, whose length is placedat right angles to this frame, travels on thetracks on wheels. The subframe in turn hastracks on which the tube-box itself travelscrosswise of the table. The tube-box can bebrought out beyond the end of the table. Tothe subframe is fastened a pair of uprights,which are grooved on their opposing lead-lined board slides up and down in thisgroove like a window sash in the frame. Asecond tube-box is fastened to the back of thisboard and the Avhole thing is second tube-box moves lengthwise alongthe table. When the subframe is moved, bothtubes move lengthwise together.
