In harvesting sugar cane l the cane is cut close to the soil. In fact, it is usually cut 05 a short distance under the soil so as to protect the rooted plants or stubs in I order to yield a good stand of cane for the following season and, also. for the reason i that there is more sugar in the cane closer to the roots than at the tops thereof. There- I tore, no stubs are left to project above the t soil, and for the purposes of my invention. l the cut canes or stalks are laid crosswise of i the furrows from hill to hill. Preferably, for convenience in harvesting, to. facilitate handling and loading, and to minimize the costthereof, the canes or stalks cut from i three adjacent hills or rowsare laid in a single row crosswise of the furrow between two adjacent hills so that throughout the I field the cut canes will be symmetrically arranged crosswise in rows with a space of two I open furrows and one unoccup1ed hill be tween each row of cut canes so arranged. 1 This arrangement permits of the passage of l a wagon lengthwise of the open furrows and i also permits of the progressive travel of view partly in side elevation and l the loading machine without disturbing the able platform 1 which is mounted on suit able traction wheels 2. The machine is provided with suitable propelling and steering mechanism hereinafter more fully set forth. The traction wheels 2 are prefe ably spaced apart a distance suliicient to straddle from middleto middle of two adjacent furrows. At the front of the platform is mounted a derrick or crane comprising a rotatable mast 3 which is mounted at one front corner of said platform 1 and at a point to be substantially medially above the furrow when the 'machine is in operation. Preferably, this mast comprises two parallel channel members 4 having their flanges disposed inwardly. At the top of the mast is secured a casting or forging 5 from which projects an upstanding pivot stud or projection (3 to which the upper ends of stay members 7 and 8,,respectively, are pivotally connected. The stay member 7 is secured at its lower end to the rear of the platform 1 while the stay member 8 is likewise secured to the side of the platform opposite to that on which the mast is mounted. The lower ends of the channel members t of the mast are riveted or bolted to a base casting or turn-table 9 which is provided with a central hub or bearing'portion 1t) and a segmental, peripheally toothed worm wheel 11 which is arranged to mesh with a worm screw 12 cured on a driving shaft 13 and whereby the mast may be rotated as hereinafter more fully set forth. The central bearing portion or hub 10 of the turntable is swiveled on a cylindrical tubular projection 1 1 on a. hollow supporting casting or base 15. This supportingmember has a series of grooved pulleys or sheaves ll) journaltal therein and under which the respective operating cables or ropes of the gathering and loading mechanisms are passed.

The gathering and loading mechanism comprises a structural swinging frame or boom which is pivotally connected at one end to the mast 3 and has pivotally motmted on its outer end a carrier frame for the. gathering and dumping devices. lreferably,the boom frame comprises two parallel channel side members 17 which are connected by cross tie members or angles 18. llinge memhere 19 are secured to theinncr end portions of the channel members 17. These hinge members are arranged to fit in vertically bifurcated lugs 20 located on the turntable 9 -,on opposite sides of the mast. The cars or forks of the bifurcated lugs 20 are provided with alining perforations 21. adapted to receive th e.pi.vot bolts 22 for the hinges.

I The boom frame has a depending bracket .l

vide guideways or tracks for a frame at its inner end comprising downwardly extending members or angles 223 at each side which are rigidly connected to the respective channel members 17 and have cross connecting members or angles Preferably, the lowernmst cross connecting angle 24 is secured to the extreme lower end portions of the downwardly extending angles 23 and the intermediate cross angle 241-.islocated a short distance above said lowermost; angle Qet so as to serve as rests and limiting stops for the end portion of a -arrier frame which is pivotally mounted on the outer end of the boom f'ame. Said depending bracket fr: me further comprises diagonal stays or braces 25 which are rigidly connected to the channel members 17 and to the lower end portions of said members .The carrier frame preferably comprises a parallel pair of channel members 26 having their flanges inwardly disposed so as to progathering device as will hereinafter be more fully set forth. The channel side nwmbm's 2b are connected at their inner ends by, cross con necting members or angles 27 and at suitable intervals throughout their lengths by tie members or angles 28. l'tigidly secured to the outer ends of the side memlwrs 526 is an upstanding frame comprising upright side posts or angles 29 and cross members or angles 30. The upper end portions. of the perpendicular side posts are connected to the inclined braces or stay u'iembers 31 which I :urecmnrected at their lower ends to the side members 26 near the inner ends thereof. The two inclined braces 31 are preferably connected by cross tie-members or angles 32, and it is also preferable to provide gusset plates 3 at the joints of both the boom and the carrier. frame structures. So. too. the frames may be. otherwise stillened by pro viding ordinarv lattice work or diagonal cross braces in any obvious arrangennmt. (not shown).

The carrier frame is provided with perforated cars or hinge members 34 on opposite sides thereof near its outer end which are adapted to coiiperate with perforated hinge. members 35 secured on the outer end portions of the. boom frame members 17. A rod or shaft 3G is passed through the hinge members fl l and 35 so as to constitute the pivot pin for the hinges and it has a grooved pulley or sheave 37 journalcd thereon about. midway between the sides of the frames. A second pulley or sheave 38 is journaled'above said first mentioned pulley in vertical aline ment therewith and in close relation there to. This second mentioned pulley ismounted on a shaft 39 which is carried by upstanding brackets or arms 40 secured on the shaft 36 on each side of the pulley 37. These pulleys serve to guide the rope for operating the gathering device.

.l'liugedly n'iounted on the front or outer end of the carrier frame is a dumping frame comprising channel side members l1 having their flanges disposed inwardly. hese cham'icl members are of. the shape and size to correspond to the channel members 26 of the carrier frame and are arranged to constitute a. continuation of the same when the dumping frame is in closed position. The dumping frame further comprises a perpendicular inner end portion comgn'ising side posts or angles 42 and cross tie niemhers or angles l3 corrcsptmding substantially to the perpendicular outer end portion of the carrier frame against which it abuts in the closed posi ion of the duu'iping fran'ie. The dumping frame further comprises diagonal braces M which extend from the top of the perpendicular inner end portion down to the outer end portions of the channel members 41.

A cover plate i3 is secured to the channel members ll across the forward portion of the dumping frame and this cover plate is preferably reinforced by an angle 46 secured on its upper face along its front marginal portion. A cross tie member or angle 47 is secured to the channel member 4-1 across the rear portion of the dumping frame. A pair of plates or brackets d8 are secured to this cross mcnihcr 47 and to the lower cross member 43. These plates or brackets support a shaft 49 on which is journaled a grooved pulley or sheave 50 adapted to cooperate with the operating;- rope for the gathering device.

Atthe front of the dumping frame is mounted a rock shaft 51 which is provided with a series of holes diaimtrically' therethrough. Bars or fingers 52 are adtinstahly secured in said holes by et screws 53.

Notchcd dislts 54- are fixedly mounted on the rock shaft 51 so as to cooperate with pivotal dogs or pawls 55 which are fixedly secured on a rock shaft 56 whici journaled on the dumping frame inwardly from the first mentioned rock shaft 51. The dogs 55 are resiliently held in enga ement with the notched portion of the islzs 54 by springs 57 which are interposed between the top of the plate 4-5 and the arms 58 fixedly secured on the rock shaft 56. The notched disks and holding dogs are arranged so that the fingers or prongs 52 are held normally perpendicularly pendent from the dumping frame. The fingers are limited in swinging in one direction by a cross member or angle 5!) which is secured at its ends to the under-- sides of the channel members 4.1.

The tripping device for the dogs or pawls 73 comprises a later 0" arm which is fixedly smeared on the roclt shaft 36. is arm connected by a rod ill to a SllllllQl arm 85.? of a bell crank whose olhcr arm 63 is bifurcated lo li'lHllllP a trigger member l l l l l l l l l which is pirotally mounted on a cross bar in the upper portion of the dumping frame. The trigge member. comprises a yoke or slotted frame in which av cross head 66 is slidahly i'nounted. This cross head is connected to a rod 67 which projects through an opening in the bottom of the yoke or frame U5 and is proyidcd with a loop or eye (33 to which thc dumping rope attached. The cross head projects latcrally from opposite sides of the yoke so as to overhang the forks of the bifurcated arm 63 of the bell crank in order to engage and actuate the same when it is desired to throw the dogs out of cng'ao'cnu-m with the disks it in a manner hereinafter more fully set forth. Jlhe cross head ()6 and rod 67 are held normally retracted by a spring (39 which is coiled about the rod betwccn the cross head and the lower end of the yoke.

The boom and carrier frames are held normally suspended in lowered position with the dumping frame folded back In closed position against the carrier frame by stay chains or cables T0 whicharc [)l'f'ffll ably connected at. one end to the cross bar 61- in the upper part of the dumping frame and have their opposite ends secured to the upper portion of the mast. Preferably, two stay chains are employed and they are arranged in parallel relation so as to evenly balance the suspended frames.

The gatheriiig device comprises a frame comprising two parallel elongated side memhers 71 which are preferably angles arranged with one flange or leg vertical and having their horizontal flanges or legs disposed inwardly. Rollers 72 are journaled on stub shafts or studs vertical flanges of said. side members 71. These rollers are adapted to travel in the trackways provided by the inwardly disposed llangcs of the channel members 26 and 4-1. respectively, of the carrier and dumping frames. The rear end portions of the angle members 71 are riveted or otherwise rigidly secured to the horizontal portion T? of an angularly bent plate whose cud unn-grinal portion is reinforced by an angle Tl sc cured to the under face thereof. Said bent plate has a downturned perpcndicular portion 75 which is provided with lateral cXtcnsions or wings 75 Preferably. the wings or extensions 75 are bent forwardly at a slight angle with respect to the downturncd portion 77 of the. plate. stiffening members or angles 76 are secured across the front faces of the portions T? and its lateral cxtension 75 on a line with the upper and lower marginal portions of said extensions. Diagonal braces 7? are preferablyconnecteo to the rear of the horizontal and downturned portions 73 and 75, respectively, of the plate o as to further stiffen the structure. The ;'athcring device further com- 72 secured to theprises a series of horizontal prongs or tingers 78 having upturned portions 79 which are secured on the back of the (lownturned portion of the plate. On the backs of the wings or extensions 75 are mounted'down- \vardly projecting lingers 80. These proi'igs or fingers 78 and 80 are prefe ably slidably mounted in yokcs or seats 81 and secured by set. screws orother suitable devices 82 so as to be adjusted vertically to conform to the contour of the furrow as shown in dotted lines in Fig. 8. The fingers or prongs on the. dumping frame' may also be similarly adjusted.

The gathering device. is actuated by a rope or cable which will be referred to as the loading rope. This rope is prefe'ably attached at one end to a rock arm or lever 83 which has a limited movement and is resiliently held norn'i'ally in a rearwai'd position. Preferably, this arm or lever through a slot in the. horizontal plate 73 and is fixedly mounted is journaled in brackets on the underside of said horizontal plate '73. This rock shaft -lhas (logs, or pawls 85 secured on its ends .so as to impinge against the undersides of the channel members QG 'and 41, respectively, of the carrier and dmnping frames. The loading or operating rope so is passed through an eye in a lugor projection 87 on the Vertical, plate 75.

S8 is coiled around said rope between said projection 87 and the rock arm 83 whereby said rock arm is restored to normal or retracted position when the pull upon the loading rope is relinquished, and whereby said dog's are resiliently held in contact with the channel men'lbers 2t and 41.. The loading rope 8b is carried forwardly and over a. pulley 8S) journaled on the middle portion of the shaft 51 at the front of the dumping frame, thence rearwardly over between the pulleys 37 and 38 at the front of the -arrier frame, over a pulley 90 at the bottom, of the mast t, and thence to a suitable winding and controlling mechanism.

Preferably, horizontal for *ardly projecting lingers 78 are provided attt'he top of the gathering device in substantially parallel relation to the middle gathering lingers 78.

A hoisting rope or cablev ttl is secured to the outer portion of the boom frame. preferably near the middle thereof. This rope mav be convtaiiently attached to the shaft 3d at the outer end of the boom frame and carried over the uppermost pulley J2 on the mast. 3. and thence to a suitable winding and controlling mechanism.

A dumping rope. 93 is attached to the tripping device and carried over the intermediate pulley ttlon the mast 3 and thence to a suitable winding and controlling mechanism. The several winding and control- 83 projects on a rock shaft 84: which Preferably, a sprin the pulley 50 at. the rear of said dumping frame,

ling mechanisms are preferably similar and will be hereinafter more fully set forth.

The operation of so much of the machine As hcreinbefore stated the cut *anes or stalks are laid in rows crosswise of a furrow between two adjacent; hills with an open space of two furrows between each row of cut canes so arranged throughout the field. The wagon W upon which the. cane is to be load.- ed, straddles the hills between the two open furrowsto the left of the row of cut canes (see Fig. 2 of the drawi'ngs) The wheels of the rmming gear are preferably spaced apart a. distance to run on the bottoms of the furrows as shown. The traction wheels on the left hand side of the portable plat-form travel behind the gathering device in the furrow across which the row of cut canes 1 being gathered are laid while the wheels on the opposite side of the platform travel in y the furrow on the right of the row of canes 1 being gathered. i The boom and carrier frames are lowered y to a position substantially as shown in Fig.1

l at the rear end of the carrier frame and beyond the end of the row of cane to be gathl cred. The winding mechanism for the loath ing or operating rope 86 for the gathering l device is operated to draw said gathering de l vice forwardly on the carrier frame with its l horizontal prongs or forks dragging on the ground bentmth the canes suspended across 1 the furrow. v The hinged arrangement of the 1 carrier frame on the boom frame permits of i a limited swinging movement of said carrier t frame so as to permit. the gathering device to' into a tight. bundle. The arrangement of the downwardly projecting fingers 80 on the ftn'wardlv bentlateral wings 75 of the gathering device insures the binding of the bunt die of canes near the Bl'ldStllClQOf. \Vhen the bundle is securely clamped on the gathering dei'ice, the winding mechanism for the hoisting rope 9,1 is operated so as to raise the. boom and :arrier frames. As said frames are being raised the hinged dumping frame will open away from the carrier frame by its own weight. During this actuation of the parts, the stay chains 70 sustain the upper end portion of the dumping frame and limit the dumping position thereof. After the frames have been raised, the mast 'is rotated substantially a quarter turn so as i to swing the dumping frame above the body as has been. herein set forth is as follows:

said gathered -anes are clamped and bound f The machine inaythen be moved forwardly of a wagon ..'disks Set on the shaft 51 which i the gathering bundle of canes, beginning at the point to the side of the machine. as shown in Fig. 2 of the drawings. The dumping rope 93 is then actuated sutlicieinly to trip the mechanism for throwing the carrying the 1 52 at the front of the dumping frame, whereupon said fingers will be free to swing outwardly as shown in dotted lines in said Fig. 5 2 and thereby release the bundle of canes 5 ill then fall into the wagon. After the load is dumped from the gathering device, the dumping rope 93 is further actuated to fold or close the dumping frame back against the carrier frame and the mast may then he turned to bring the frame in front of the platform as shown in Fig. 3 of the drawings. The loading rope 86 is then let. out sutlicientlv to permit the gathering device to return to normal or first position on the carrier frame as shown in said Fig. 3.

and thefram'es lowered into-position so that device may gather another where the depending fingers 52 of the dump ing frame rested during the gatl'iering of the previous bundle.

Any suitable propelling and steering mechanism may be provided for the portable platform 1. Preferably'the front axle 95 is the driving axle. On. this axle is fixedly secured a worm wheel 96 which meshes with worm screw'fi'l' on'a shaft 98. This shaft is jouriialed at one end in a gear casing or housing 99 which surrounds said worm wheel and screw. It extends upwardly at an incline to a point above the platform 1 where it is journaled in a bearing 100. On the upper end of the shaft 98 is fixed a bevel pinion 101' which is adapted to mesh with two oppositely disposed r versing gears of.,a clutch .niechanisin such- 5 is illustrated in Fig. 12 of the drawings. The clutch mechanisms for the propelling. st-turniiig and winding devices are prefera similar, and, therefore, will be shown me -ely diagramiiia-ticallv in Figs. 10 and l l. and in detail in I l "Figs. 12 to 14, inclusive, of the drawings. i jglteferring now more particularly to Figs.

The drivi iiig shaft 103 which is connected to the III() I tor has a bevel gear 104 thereon whichl meshes with a similar gear 105 on a jack shaft 106. This jack shaft operatively connected with the clutch mechanism 107i for the propelling device hereinreferred to, l and it has on itseiid ahevel gear 108 whit meshes with a like. gear 109 on a line she 110. This line shaft has i gear or pi a lllth'crcon which meshes with a gear hereinafter more fullv set forth. shaft 110 extends 110 so as der is provided with ports 140.

compressor suitable construcair compressor any suitable i pipe connection may be made to air receivers 'pawls out of engagenienthvith the notched I l .114 which may supply compressed air to the several controlling devices in a manner The line longitudinalh on one side and i operatively connected with a series of clutch mechanisms 115, 116, HT, 118 for the respective winding devices 119, 120. 121 of the hoisting. gatlu-zring and of the platform dumping mechanisms. and the driving shaft.

1 3 of the mast-turning mechanism.

Referring now to Figs. 12 to 14, inclusive, a winding drum 129 is secured on a shaft. 123 which is journaled in a frame 124: which may be mounted on the platform 1. The

shaft 123 also-has secured thereon a Worni wheel 125. The. worm wheel meshes with a worm screw 126 which is secured on a cross shaft 127 which is journaled in said frame 124. This shaft 127 has a bevel pinion 1:28 on its end which meshes with two oppositely disposed bevel gears 129, 130, respectivelv,

which are loosely mounted on said line shaft to rotate freely thereon but are held from moving endwise thereof. lref- Bill-Ebb, the gears 12%), 130, have abutting hub portions 131 which are grooved peripherally so as to cooperate witl'i a counterpart portion of an annular coupling member 132. Said gears are provided with an outwardly flaring circular pocket 133 in their outer ends-1 adapted to receive the tapered clutching portion 134- et oppositely disposed clutch iiien hers 135 which are feathered on the driving shaft llt'l. These clutch members 135 are arranged to be shifted on the shaft; and held in clutching position relative to their respective gears 125)., 130, by pivotally mounted yokes 136 which preferably have a slotand pin connection with the outwardlv projecting rods of pistons 137.138, respec tivelv, in an air cylinder 13!). This cylin- H-l. respectively. at each end thereof which communi cute with air pipes A B respectively. in-

erubl v, these controlling devices are convei'ii'ently arranged in a closely arranged series on a. common supporting frame 143 (see Figs. 17 and 18) which may be mounted in any desirable position on the portable platform so as to be within reach of an operator. Preferably, the respective controllingdevices comprise oppositely disposed, reversing throttle valves, 144, 145, which are preferably mounted on opposite sides of a hollow casting or air duct 146 which is mounted on the sum'iorting frame 143. This air duct. is connected with a supply pipe 147 which communicates with one of the compressed air receivers 114 in any suitable manner. The air duct 146 is provided witha series of openings 148 in its opposite sides which connnunicate with ports 149 in the 'astings for the respective controlling valves 144, 145 which are secured on said air duct. The controlling valve castings have vertical cylindrically' bored chambers with which said ports 14$) communicate. mounted in each of said cylindrical chambers is a cylindrical valve block having enlargements or heads 150, 151 and a reduced intermediate portion 152. The valve blocks have stem portions 153, 154 projecting from opposite ends thereof through central openings in the top and bottom heads, respectively, of said valve cylinders. A spring 155 is coiled around the lower stern of each valve block inside of the cylinder so that the block is resiliently held in normally raised position. The valve blocks are so proportioned that their lower heads 151 normally close the ports 149 in the valve castings, and the reduced intermediate portions of the blocks are of such a length that communication is normally established between an exhaust port156 in the valve casting and a port 157 therein which communicates with an air pipe A. or B according to which one of the pair of va ves is referred to. The distance from the exhaust port 156 to the port 157 is substantially the same as the distance between said port 157 and the port 149 so that when the valve block is depressed communication is established between said two ,last mentioned ports. In the depressed position of the valve block the exhaust port 156 I is closed by the upper head 150 of the valve v block as shown to the right in Fig. 15 of the drawings.

Pivot-ally mounted between pairs of lugs 158,011 the air duct 146 is a series of hand levers 159, there being a single lever for each pair of reversing throttle- valves 144, 145. These hand levers are provided with oppositely extending lateral arms 160 which overhang the upwardly projecting valve stems 1.13. Normally, the hand levers are held in vertical position by the resiliently mounted valve blocks whose stems 153 bear against the undersides of said laterally projecting arms 160 as shown in Fig. 18 of the drawings. By this arrangement, the hand overs may be rocked toward either side of Slidably the air duct as the case ma be to depress the block in the valve it is (T OSlIGd to actuate. Thus, for example when it is desired to actuate one of the clutch mechanisms to drive its companion winding or operating device in one direction, the hand lever for that particular mechanism may be moved as shown in Fig. 15 of the drawings. As illustrated, communication tween the air supply duct 146 and the air pipe A which preferably communicates with a port 161 in a safety valve casting or cyL inderv A (see Figs. 13 and 16 of the drawings). A second air pipe communicates with a port 162 which opens into the valve chamber at a point adjacentto said first mentioned port 161. This air pipe A leads to the port. 140 at the end A of the clutch air cylinder 39. behind the outer, face of the piston 137, said piston will be movedinwardly and thereby the clutch member 135 will be forced into engagement with the gear 1'21). Thus the motion is transmitted from the driving shaft to the bevel gear 128 of the shaft 127 of the winding or operatin case may be. When it is desired to stop the rotation of the driven shaft 127, the hand leverv 159 is moved or restored to normal position thereby permitting the spring to restore the valve block in the throttle-wilve 144 to normal position, whereupon the pressure in the air pipes A, A and the clutch air cylinder is exhausted through the (5X1 haust port 156 in said throttle-valve casing 144.
