Details of a Wall Mounted Candle Lantern are shown in Fig. C-5. The lantern is fitted with a device to raise the candle for ease of lighting. Draw a full size sectional elevation on A-A, showing the parts fully assembled with the height adjustment lever (part 3) in the horizontal position and the candle platform (part 6) in the fully lowered position. (Unless otherwise stated, all fillets are 1.5x45° and any omitted dimensions may be estimated.) (b) Determine and indicate in millimetres on your drawing the maximum height travel of the platform when it is raised by the height adjustment lever.

Answer

To determine the maximum height travel of the platform, calculate the total distance the height adjustment lever can raise the candle platform. Measure the maximum angle through which the lever can operate and translate that into vertical height based on the linkage system in place. Sketch this distance noted in millimeters on the drawing.
