' I 9 j The: mechanism for .driving the shafts of the drag from the-shaft '29 ofthe elevator .is shown in Figs. 1', 2*, 5'; 9 and 10;. where" .it"willbe"seen that theshaft 29 has on the o -lter-enditheneof the sprocket-wheel 3$-(lr"iv ing'.

The drag32-is provided with thestraps 61 projecting -.upwardly from the inner end thereof and, terminating; in the 'hooks '62,- best shown in. Figs. 5 and 8,which have the swinging latches (3-3 pivoted thereon so that the ends-of the drag can be hung upon 'the :outer ends of the'shaft58 inside of thecollars 6st. The shaft-58 has on one end thereof a the sprocket-wheel 65 which through the me- 1 V J (hum of the sprocket-chain 66 cooperating t'ion, Ihingeor join-the drag to thebottom and this no matter 'at'wh-at angle the drag may be placed tothe elevator, the placing 'ofthe 'drag at anyposition'being the object of providing the gearing shown. It is to permit the drag to be swung around at either side'thereof that I- employ theofi-set ar-V 'rangement of the sprocket-chains 39 and i3, audit. will :be apparent that I might secure the same result 'by-"'employing' a single sprocket-chain 39', as shown 111 Fig. 3, and

substituting 'for the double sprocket-wheel 4( two sprocket-wheels 40 placed on different shafts, the "sprocket-wheels 4:0 in this -latt er'- construction operating merely as guide-rollers.

A pin 108 projecting up om the rod 100-engages the end piece 107, so that the plate 106 moves back and forth with the side board as it is adjusted longitudinally; 'The forward end of the plate is guided by the angle-iron pieces 109 and 1-10. The piece 109 is secured on the top of the side iece and its vertical flange is ata sufiicient istance therefrom so as to make a guide-way for the top of the plate 106 and the lower angle-iron 110 has its horizontal flange set into the side of the trough as shown, and-its vertical 'fiange at a suitable distance therefrom so as to furnish the channel for thelower' portion of the plate 106. The side of the trough has the 7 channel 111 cut therein, as shown, to accommodate the end of the rod 100 as the side board is shoved toward the discharge end of the drag. I

It will be apparent that the side board '33 of-the cross. conveyer constitutes a shiftable chute on one side thereof, which cooperates with the stationary side portion 88,,which,

with its straps 102' and 105, constitutes a supporting and guiding member (ifv greater I length than the chute sup orted thereby;

and that the opposite side 0 the trough constitutes a vertical .fixed stop. board at the other side of the coiiveyer.
