Instead of these wheels other gear may 5 be substituted, as represented in Fig. 5. The longitudinal shafts G, G, are for effecting the movements of the racks I and L; and II is the toothed segment for raising the head frame D. I, ascending racks to the top of which the two lateral shafts R are affixed. Those shafts R are for distending the sacking of a bed, if required ; and by means of the racks I, L, the suspended sacking may 10 be raised or lowered, the manner of distending the sacking being shewn in Fig. 4.
