Abstract

1,171,051. Endless conveyers. AEROJET-GENERAL CORP. 9 Feb., 1968, No. 6566/68. Heading B8A. A vertical sorting conveyer system comprises a carrier 28 movable on a frame 7 and having a tray 35 movable between an initial position (Fig. 8A) and an extended position (Fig. 8B) for transfer of cargo 45, actuating mechanism for effecting the movement of the tray 35 comprising an abutment 200 movable relative to the carrier frame, an operator controlled abutment 205 disposed to be moved into the path of the abutment 200, and means connecting the abutment 200 with the tray and operative to effect movement of the tray (when the abutment 205 is moved by the operator) to move it into its extended position. There are a plurality of carriers 28 and they are each pivotally connected at 116 (Fig. 5) to an endless traction chain 15. When the cargo 45 waiting on tines at a loading station 43, is intended to be picked up by a rising carrier 28, the abutment 205 at the station 43 is moved by operator control to dot-dash position (Fig. 4). The abutment 200 on an endless chain 90 mounted in the frame of the carrier 28 is then engaged by the abutment 205 as upward travel of the carrier proceeds. Chain 90 is thereby caused to move, and transmits movement to a horizontally disposed chain 127 carrying a pusher 180. The latter is in sliding engagement with a bore in a member 192 rigid with the tray 35. Thus the latter is projected into an article receiving position (Fig. 8B and dot-dash position Fig. 7). After loading has taken place at station 43, the tray is automatically retracted (Fig. 8C) by the action of a stop 225 engaging a fixed stop 230. A similar arrangement results in projection of the tray on the downward travel of the carrier 28 if an operator controlled stop 238 is projected, so as to engage a stop 235 carried by an endless chain 95. Discharge thus takes place on to forks at a station 50. On the vertical upward and downward runs of the elevator the carrier 28 is guided by parallel guide rails 60 (Fig. 4). As the carrier passes across from its upward to its downward run or vice-versa it passes out of the guides 60 and engages vertical rollerways (55), (55), (Fig. 1, not shown).
