  • the charger may comprise a fixed rear wall and the closure means may comprise a pivoted front wall having means to support a removable top wall which constitutes the said removable part.

  • the charger- may be swung about its pivot by mechanism set into operation by a press button or like control, the arrangement being such that the charger swings over to the discharging position and then returns to the tray receiving or loading position whereafter said mechanism 'ceases to operate until the button ispressed again.
  • the pivoted top wall may be held in its operative position by a latch which is trippedwhen the charger arrives at the discharging position whereupon the top wall moves on its pivots under the influence Of a spring.
  • Means may be provided for preventing the operation of the charger swinging mechanism to move the charger from the loading position until the top wall is latched in position.

  • Catches 'or the like may be provided on the pivoted front wall adapted to engage the tray and to carry it with the wall when the latter swings open about its pivots. This provision fa- 3 cilitates rapid operation of the charger when large quentities of cigarettes are being handled.
  • the pivoted top wall may comprise a series of flat springs or pressers adapted to move into contact with the cigarettes along the length of the charger to prevent displacement or rolling of the cigarettes as the charger swings over in its pivoting movement.

  • the lugs pass through holes or slots 83, Figure 2, in the rear wall 5 of the charger, and as the tray cannot fall out, except by a downward movement, which the'lugs prevent, the tray is securely held.
  • the tray is located lengthwise of the charger by guides 86, Figures 2 and 3, fixed to the front wall and which pass between the hooks of the tray.

  • the bar 63 has a notch 65 in it of the same shape as a notch in the block 64 and when the two notches are aligned the arm 48 of the bell-crank lever can pass and the pivoting movement of the stop lever 42 to allow the pawl 43 to engage can take place.
  • a spring 36 returns the bar 63 tothe stop position when the pivoted lever 5'! is free of the arm 58 on the charger, that is, when the framework l3 of the charger is unlatched.
  • ratchet stop device is fitted, also shown in Figures 6 and 7.

  • the pawl 69 clears the cam face 14 and-springs into engagement with the teeth of the ratchet wheel '12, long before there is any overrunm'ng load due to the weight of the charger, and as the wheel 72 is fixed to the wheel 38 the pawl 69 charger is inverted-over theh'opper.
