Trapezoidal Window

Fan oscillating drive mechanism

The Exhibit is made out of 4mm sun board with grey, light grey and black coloured vinyl applied on either sides. The Drive assembly is hung from the roof so that the exhibit is slightly above the eye level. For the slow speed drive we have used the Table fan's osscillating gear box.

SLIT HORSE

Rope winding to drum and the clutch assembly

For the sliding we have used the steel telescopic drawer slide. The slide is moved be a rope wound on a drum. To avoid the strain on the rope when the end of travel is reached , we have added a clutch to slip. The return of the slide is done with the help of a counter weight.
