U A
; the angle
U A W′
is the loss of lift. This angle must be added to the lifting angle of the pallets; we see that in this action there is no loss on the engaging pallet, but on the disengaging the loss amounts to approximately ⅞° in the action illustrated. As we have allowed ¼° of run for the pallets, the discharging edge
P
is removed at this angle from
U A
; we do not illustrate it, as the lines would cause confusion being so close together. The lifting angle on the pallet is measured from the point
P
and amounts to 5½° + the angle of the loss; the angle
