By means of a sprocket-chain 41 and is provided with a. lever 42 andabrace 6 power is conveyed from the crusher to the 43, as shown more particularly in Fig. 3. rollers 7, which drive the endless traveling Upon the lower end of the lever 42 is an iron hood .44, which isen a r-d by achain 45. This chain passes over pulleys 46 i 48 and chainwhcel -19 and is thereby connected with a f gearing 50, controllable by a hand-wheel it will be seen from Fig. that by turning the hand-wheel 51 to the right or to the left the lever 42 may at will be drawn from its posi tion shown in full lines to that shown in dotted lines. The platform 40 is provided with rails 52, upon which the cane-car 53 is supported. Mounted upon the side of thecar53 is a cleat 54. Thiscleatisdetachablyengaged by a hook 55, provided with a turnbuckle 56 and revoluble head 57., mounted upon the shaft 58, which rests in bearings 59- The shaft 58 is provided with a fork 60, which may be turned within certain limits by lowering the hook to a substantially horizontal position. A hasp ($1 is secured fixedly in position by means of bolts 62. 'hen the operator desi res to dump cane from the car 53, he raises the hook into the position indicated in Figs. Sand thereby causing the hook to engage the cleat 54. B3: manipulating the hand-wheel as above deseribrd the car may be dumped, as indicated by dotted iines in Fig. 3. Thehook by binding firmly upon the cleat 5t prevents the car from leaving the rail. The car being dumped and restored to the position indicated in full lines in Fig. 3, the hook fifiisdetached from the eleat and is lowered to a horizontal position. thereby causing the fork 60 to assumc a vertical position. oneoftheforks, b0", being thereby carried directly beneath the hasp 61 and preventing the platform 40 from being tilted at an inopportune moment so as todumpthecar. The hasp 61 is mounted upon a stationary flooringfif-i. A fender64 depends from the platform, and a bevel 66 is provided for the purpose of facilitating the sliding of th cane downward upon thecarrier 17. The door of the ear is shown at am] alsoconstitutes an inclined surface over which the cane may travel freely. if desired, however, the car 53 need not be used for dumping the cane, which step may b:- performed by hand or by an unloadbig-machine.

It will be seen from Fig. 4 that the traveling apron IT is somewhat lH'Hih'lL! than the traveling apron S. bution'of thccanc is rendered somewhat more effective, because as tlucane passes from the upper apron tothe lower one the tendency is to makithe layer of the cane slightly deeper .j

upon the lower traveling apron. It will be also holed that the guard 67, which is pro- ,vidcd with mutilations 6'5, serves as a fender 'fonprevI-nting the came from lmingdrawn out A somewhat I The purpose of this guard is to prrv nl cane from passing By its use cane is fed f belie-ail: the endless apron 17. similar guard is shown at l3.

over the cutters H. beneath the cutter. |n all cases the cutters have a higher speed than the speed of the traveling cane.

By this means the distril The operation of my device is as follows: i After the cane is dumped by hand or by an uuloading-ruachimit is m rely thrown evenly upon the carrier 17. If. however. it is desired to dump the cane by the mechanism described, the ca 53 is moved out upon therails 59,.the hook 555 is placed upon the chat 54, and the hand-wheel 51 is manipulated for the i purpose of dumping the cane upon the carrier 17. This manipulation (.lispenses with all the laborers heretofore used on the carrier and unloading-machines. Of course some care must be exercised in manipulating the handwheel 51, so that the cane is dumped with considerable uniformity. The fingers 19. together with the motion of the carrier 17. tends to distribute the cane still more equally. The cane is now carried up the incline represented by the uppersurface of the carrier 17, and any excess of cane resting upon the carrier is vigorously manipulated by the fingers 33 upon the belt 32 and also by the knives 3-! upon this belt. The fingers 33 and knives 34 have a motion contra? to that-of the belt 17am also have greater. rapidity. Should a large mass of cane chance tolodge upon any given portion of the carrier 17, the mass upon reaching theouter or free end of the belt Iii-3 and being operated upon by the lingers and knives 33 34 thrown backward, and thus partially scattered down the inclined surface of the carrier 17. Xormallythis is all that occurs in case of a large pile of cane coming up at the same time to the fingers and knives. ()ceasionally it may happen, however, when such a gorge of cane occurs that the fingers and .knives arennable to scatter the accumulation, and'in this event the mass of cane causes the roller 31 to be lifted bodily, thereby preventing breakage of the knives and lingers and allowing the excess of cane to .mss. The cane passes from the upper or left-hand end of the carrier 17 to the lower end of thccarrier-belt8, from w h i ch i t is conveyed upward to the chute 4. lust before passing into the chute, however, the cane is subjected to a second manipulation by the 'revoiubie knives Hfwhich travel in the same direction to that of the cane and render the distribution of the cane still more effective. It will be understood, of course, that all of the knives used have a sullicient speed to cut projecting stalks of cane and that imlcpendently of their cutting function they serve as distributers. The cane next passes into the chute 4, entering at the larger upper crusher. l Having thus described my invention. I claim as new and dcsi re to secu rc by Letters Patent- 1.
