The object of this invention is to provide sugar-cane harvesters constructed in such a manner as to cut and top sugarcane and sorghum, and deposit the cane or stalks in wagons drawn at the side of the harvesters.

The invention consists in a sugar-cane har vester constructed with wheels and axle, and a frame provided with an endless chain of knives, two pairs of vertical shafts having chain-wheels, a horizontal shaft having chainwheels, endless chains having arms carried by the said chain-wheels and moving in guides, and a driving mechanism, whereby the cane will be cut and the stalks raised, brought into a horizontal position,and discharged from the machine. The knives are provided with connecting links orlugs moving in guide-bars attached to the frame, and protected from wear by a steel facing-plate, whereby the said knives are held in place and protected from the stalks. The vertical shafts are held erect by arms having bearings at their-outer ends, and attached to vertical posts of the frame. The links of the lower and middle endless chains of the elevator are provided with U-shaped flanges, to which projecting arms are secured by pins or bolts, whereby the said chains are adapted to carry the stalks. The links of the endless elevator-chains move in recessed guides which have grooves at the sides of their recesses to receive the edges of the said links and guide the said chains. The endless-chain guides are supported from the frame and held in place by forked brackets provided with set-screws. The tops are cut from the stalks by revolving knives working at the side of a stationary knife, and driven by a band and pulleys from the horizontal shaft, as will be hereinafter fully described.

A represents the drive-wheels, the axle B of which is connected with the frame 0 by bearings D.

To the forward part of the frame 0 is attached the tongue E, the connection being strengthened by braces F, attached to the said tongue and to the front cross-bar of the said frame.

To one of the drive-wheels A is attached a gear-wheel, G, the teeth of which mesh into the teeth of the small gear-wheel H, placed upon the rear end of the shaft I. The shaft I revolves in bearings attached to the frame 0, and to its forward end is attached a chain-wheel or pulley, J, around which passes an endless chain or band, K. The endless chain or band K passes around guide-pulleys L, pivoted to the frame 0, around thelower part of a double chain-wheel or a chain-wheel and pulley, M, pivoted to the frame 0, and around the chain wheel or pulley N, attached to the lower end ICC of the rear vertical shaft, 0, so that motion will be given to the said chain-wheel M and vertical shaft 0 from the drive'wheel A.

1? are the knives or cutters, to the shanks of which are attached or upon them are formed lugs or links Q. The lugs or links Q of the adjacent knives P overlap,and are pivoted to each other, forming an endless chain of knives, which passes around the upper part of the double chain-wheel M, and around the chain wheel R, pivoted to the frame 0. The shanks of the knives P and the lugs or links Q slide in recesses in the adjacent sides of the bars a I), attached to the frame 0, and by which the said knives andlinks are guided, and are supported against the pressure of the stalks, the forward parts of the said knives projecting, as shown in Figs l and 5, to cut the stalks as the said knives are carried forward by the advance of the machine. The upper side of the upper bar, I), is faced with a steel plate, 0, to prevent the said bar from being worn by the friction of the stalk-butts.

d is a flanged platform, which forms a continuation of the plate a, and serves to support the butts of the stalks until such time as the said stalks are raised to such a height that when they drop from the upper end of the said platform their tops will be caught by the arms of the upper elevator-chain, and thestalks will be suspended by the said arms with all their tops at the same height, so that only the tops of the stalks will be cut off by the knives hereinafter described.

To the frame 0, in front of the inner sides of the chain-wheels M R are attached forwardprojecting arms S, which are inclined downward and curved outward, as shown in Figs. 1, 2, and 3, to serve as guides to bring the stalks into position to enter the machine.

To the frame 0, a little in front of the inner parts of the chain-wheels M R, are pivoted the lower ends of the vertical shaft T and the forward vertical shaft 0. The lower end ofthe rear shaft, 0, is also pivoted to the frame 0. The vertical shafts O T revolve in bearings in the outer ends of arms U, secured at their inner ends to posts V, placed between the shafts O and at the inner side of the, shaft T, and secured at their lower ends to the frame 0, and strengthened in vertical positions by bracerods W.

To the lower, middle, and upper parts of the vertical shafts O are attached chain-wheels X, around which pass endless chains Y.

To the endless chains Y are attached hori- "zontally-proj eeting arms Z,which,as the shafts O are revolved by the endless chain K, assist in carrying the stalks inward.

To the lower, middle, and upper parts of the vertical shaft T are attached chain-wheels 6, around which pass endless chainsf. The

a hook at one end and an eye at the other end,

and with U-shaped flanges t upon their upper sides to form recesses to receive the bases of the arms j, which are secured in place by bolts or rivets k passing through holes in the side parts of the flanges z and in the said armsj. The linksf of the upper endless chain, f, are made with a lug at one end and a pair of lugs at the other end, which lugs are perforated to receive a pin,f which passes through the pair of lugs of one link and the single lug of an adjacent link inserted between the lugs of the said pair, so as to form a hinged connection between the links. In the body of each linkf are formed holes to receive arms j, so that the said arms j will be sufficiently close together to support the stalks by their tops when they drop from the upper end of the inclined platform d. The links of the endless chainsfslide in reeessesin guide-bars Z, which have grooves in formed in them to receive the side edges of the said links and keep the said links in place in the said recesses. The guide bars Z are secured by set-screws n in recesses in brackets 0, which are attached to various parts of the frame 0 to support the said guidebars andendless chains, and which .must be made of various forms to adapt them to the 5 different positions in which they are to be placed.

Fig. 11 shows a form of bracket for connecting the guide-bars of the two parts of the chains, and Fig. 12 shows a form of bracket for attachment to a post of the frame. The stalks while being carried up the elevator are held down upon the armsj ofthe endless chains f by guide-rods 19, attached to'the frame 0,

and supported in such positions as to be a little above the said endless chains.

To the shaft h is attached a chain-wheel, q, around which passes an endless chain, r. The endless chain 1* also passes around the chain wheel 8, journaled to the frame 0, and with which is rigidly connected a gearwheel, 15. The teeth of the gear-wheel tmesh into the teeth of the gear-wheel u, attached to the end of the shaft 1), which revolves in bearings attached to the frame 0. To the inner end of the shaft 22 is attached a gear-wheel, w, the teeth of which mesh into the teeth of the large gear-wheel rs, attached to or formed upon one of the drive-wheels A, so that the elevator will be driven from the said drive wheel. With this construction, as the stalks are cut by the knives 1? they pass to the carriers in the manner hereinbefore described, are kept in place between the arms j j of the endless chains f by the guide-rods and are carried up by the said endless chains, and dropped over the shaft h, the chain-wheels 9 being so graduated in size that the endless chains carrying the butts and middle parts of the said stalks will travel so much faster than the endless chain carrying the tops of the stalks that the said stalks when they reach the shaft h will be parallel therewith, and will thus be discharged squarely from the elevator.

ICO

To the shaft h is attached a pulley or chain wheel, 3 around which passes an endless bandjournaled to a support attached to atop crossbar of the frame 0.

To the pulley or chain wheel 1 are attached curved knives 2, which, as the said pulley or chain wheel revolves, successively pass the stationary knife 3, attached to the cross-bar of the frame 0 or the support of the pulley or chain wheel 1, so that the tops of the stalks will be cut off by the knives 2 3 as the said stalks are approaching the shaft h. The chain-wheel J and gear-wheel u are placed loosely upon their shafts, and with them are rigidly connected ratchet-wheels 4. With the said shafts are rigidly connected flanged disks or casings 5, whichinclose the ratchetwheels 4, and in recesses in theinner sides of the rims of which are pivoted pawls 6. The pawls 6 are held down upon the teeth of the ratchet-wheels 4 by springs 7, attached to the rims of the said cas ings. With this construction the drive-wheels A can be turned back without giving a rearward motion to the mechanism of the machine.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a sugarcane harvester, the combination, with the wheels Aand axle B and the frame 0, of the endless chain of knives P Q, the vertical shafts O O T, having chainwheels X e, the horizontal shaft 71, having chain-wheels g, the endless chains Y f, having arms Z j j, the guides Z, and a driving mechanism, substantially as herein shown and de scribed, whereby the cane is cut and the stalks raised, brought into a horizontal position, and discharged from the machine, as set forth.
