I CANE- HARVESTER.

, Specificationof Letters Patent. Application filed November 15, 1905. seal No. 287,472.

, Patented Jan. 1,1907.

To all whom it may concern! Be it known that we, Josnrn A.'MELAN- CON and WARWICK C. MAvoR, citizens of the United States, residing at McCall, in the parish of Ascension and State of Louisiana, have invented a new and useful Cane-Harvester, of which the following is a specification.

This invention relates to cane-harvesters, and it has particular reference to machines of this class embodying mechanism for stripping and for topping the cane, as well as for cutting the same and for conveyin it to the point of discharge, the ob'ects of t e invention being to simplify an improve the construction and operation of this class of'machines and to increase the general efliciency of the same.

. -With these and other ends in view, which will readily appear as the nature of the invention is better understood, the invention corisists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.- 4

In the accompanying drawin s has been illustrated a simple and preferre form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited,

but that changes, alterations, and modifications within the scope of the invention may be made when desired.

In the drawings, Figure 1 is a top plan view of a machine constructed in accordance with the principles of the invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view taken on the plane indicated by the line 3 3 in Fig. 2. Fig. 4 is a horizontal sectional view, enlarged, taken on the plane indicated by the line 4 4 in Fig. 3 Fig. 5 is a sectional elevation illustratin the cane-cutting blades. Fig. 6 is a detail view of part of the means for transmitting motion from the tractionwheels to the stripping-arms.

Corresponding parts in the several figures are indicated throughout by similar. characters of reference.

' The frame of the improved machine is constructed, preferably, of channel-iron, which is bent in a horizontal plane to an approximate elongated U shape, including the side members 1 1, which are connected by the bent rear portion 2, the forward extremities of the side members being spaced apart and curved or diverged downwardly and outwardly, 'as shown at 3, so as to form-canegathering guides that will facilitate the admission of the stalks of cane between the side.

members of the frame.

Upon the side members of theframe near their front ends are supported standards 4, 5,

and 6, the upper ends of which are provided with boxes or bearings for shafts 7. These shafts between the standards 4 and 5 are (pg)- vided with hubs 8, havingradially-exten resilient stripping-arms 9, which may be formed of flat steel rods slightly bent or rounded at the ends. These arms are set closely together, so as to engage the stalks and strip the leaves therefrom when the machine is in operation.

10 and 11 are vertical shafts or uprights, the former of which are supported adjacent to the uprights 6, which are provided with laterally-extending brackets 12, engaging and steadying the uprights 10. The uprights 11 are disposed adjacent to braces 13, and the said shafts or uprights 11' are provided with brackets 14. Supported for rotation upon the shafts 10 and 1 1 are combined bevelgears and sprocket-Wheels including hubs 15 16,-tl1e former of which carries a bevel-gear '17 and a sprocket-wheel 18, While the latter carries a bevel-gear 19 and a sprocket-wheel 20. The sprocket- wheels 18 and 20 at each side of the machine are connected by a link 1 belt 21 and the bevel-gears17 meshwithbevelpinions 22 upon the rear ends of the stri per- .carrying shafts 7. In the braces 13 and the brackets 14 are so ported for rotation shafts 23, carryin beve inions 24, mes with the bevel-gEars 19, End the shafts 23 2i provided with sprocket-wheels 25, that are connected by link-belts 26 with sprocket-wheels 27, formed upon sleeves or hubs 28 and 29, mounted upon the driven main shaft 30 of a gasolene or other'motor M, which has been shown supported upon a platform 31 at the rear end of the frame. The sleeves or hubs 28 29 are normally loose upon the main shaft;

but they may be connected therewithfor rotation by means of suitable clutch members 32, for the manipulation of which shippinglevers 33 are provided.

The horizontally-disposed link-belts or chains 21, which are driven by the mechanwith outwardly-extending stalk-en aging pulling-arms or gathering-arms 34, which, as the machine-advances, serve to engagethe stalks of cane and to K ism just described, are provided at intervals IIO impel said stalks in a rearward direction, the purpose of which will presently be made apparent.

Firmly supported upon the side members of-the frame in rear of the shafts or uprights 10 and between the inner and the'outer leads of the chains 21 are tubular u ri hts 35, which rise to a suitable height and w ich are connected at or near their upper ends by a cross member, such as a bar or plate 36. Mounted slidably upon the tubular uprights 35 are sleeves 37, supporting between them a vertically-movable member which we will designate as the cutter-carrying head or cuttercarrying frame H. This head comprises front and rear plates 38 and 39, which are suitably connected with each other by bolts or connecting members 40, some of which extend through and are securely connected with ribs or flanges 41, formed upon the inner sides of the sleeves 37. The lower edges of the plates 38 39 are cut away to form arched recesses 42. rear lates 38 39 are also provided with vertical s ots 43, in which are adjustably mounted boxes or bearings 44, in which are journaled longitudinally-disposed parallel shafts 45, carrying circular cutters 46, preferably provided with serrated edges 47. The cuttercarrying shafts are three in number, and the cutters have-been shown as overlapping one another and dis osed closely adjacent to the rear side of the out plate 38 of the head or frame H. The latter is connected by flexible elements 48 with counterweights 49, supported within the tubular uprights 35, said acent exi'ble elements being guided over tpulleys 50, which are suitably supported a to the u per ends of the tubular uprights.

The hea j H and related parts being thus counterbalanced will practically float: and

- adjust itself automatically to various positions. It is intended that the head or frame with its related parts shall somewhat overbalance the counterweights, so that some slight force will be required to move the head in an upward direction, this force being in practice derived from contact of the head with the upper ends of the stalks, which are bent under the head by the action of the pulling-arm's 34 upon the chains 21, the object being to enable the head to be automaticallyadjustedas nearly as possible to stalks of varyin lengths, the heads or tops of the stalks eing severed by the rotary cutters,

the edges of which roject below-the recessed lower edge of the out plate 38 of the head. It will be understood that the intention of this device is to rovide an automatic adjustment whereby t e tops will be removed from stalks of cane of various lengths, the object being to avoid the unnecessary waste which would result by severing all the stalks at the level, which Wlll be neccessary in order to remove the tops from the shortest stalks or Said front and from the shortest stalks, which obviously could not be effected by a stationary cutance Where two or more stalks happen to be growing close together than where the stalks are growing singly, in which event the tendency would be for the frame or head to move upward, causing the stalks to be severed nearer their extreme upper ends than would otherwise be the case; but it may be safely asserted that the stalks as a usual thing grow with considerable uniformity, or at least with suflicient uniformity to insure practical efliciency in the operation of the device. It will be furthermore observedthat the normal resistance of the stalks is not altogether depended upon to effect the adjustment of the vertically-movable head or frame, inasmuch as the stalks by the action of the gatherin -arms 34 upon the link-belts 21 will be forci ly bent in a rearward direction beneath the vertically-movable head or frame carrying the cutters, thereby assisting materially in effecting the desired vertical adjustment of the head or frame.

For the purpose of preventing the head from dropping too low upon the guides or uprights 35 stop-collars 51 are mounted u on said uprights, said collars being prefera ly supported upon springs 52, which are coiled or wound upon t e uprights, thus forming yieldable supporting means for the cuttercarrying head.

By properly adjusting the boxes 44 the cutter-carrying shafts may be moved up or down within the head, so as to regulate the extent to which the cutting edges of the blades or cutters shall be permitted toproject. This distance should at all times be sufficient to enable the cutter to operate efficiently to sever the tops from the stalks, and the adjustment is not only rovided in order to compensate for wear, utalso to enable the device to operate efficiently under varying crop conditions.

The cutter-carrying shafts are provided with bevel-pinions 53, meshing with bevel pinions or gears 54 upon the lower ends of shafts 55, bearings for which are provided in brackets 56, connected with the rear plate of the head H. The shafts 55 are longitudinally grooved, the grooves 57 extending through the greater portion of the lengths of said shafts. The latter are extended through hubs 58, that are su ported for rotation by the top plate 36, sai hubs being rovided with collars 59, whereby they are field securely against displacement. Said hubs are provided with keys or splines 60, engag ing the grooves 57 in the shafts 55, with otherwise to insure the removal of the tops l which said hubs are thus connected forrota- IIO The top plate 36 is provided with brackets 61, su orting a horizontal shaft 62, carr a s ro dliet-wheel 63, which is connected lin -belt 64 with a sprocket-wheel u on the hub or sleeve 28 on the driven main slihft 30, from which motion may thus be transmitted to the shaft 62. From the latter shaft motion is transmitted to the hubs 58, which are provided with bevel-pinions, as 58*, through the medium of suitably-supported short shafts 59, provided at their front ends with bevel-pini'ons60, meshing with the bevel-pinions 58, and at their rear ends with bevel-pinion 61, meshing with bevel-pinions 62 upon the shaft 62. Other means for transmitting motion may be used, that sufficient speed is developed.

The side members 1 1 of the horizonta main frame of the machine are provided upon their inner'sides with boxes 66, constituting sockets in which bolt members 67 are supported for vertical adjustment by means 0 nuts 68 at their upper ends. Upon the lower headed ends of the bolt members 67 are supported for rotation sleeves 69, having flanges 70, u on which are mounted rotary cutters 71, w ich may be raised or lowered, as may be desired, by simply adjusting the nuts 68 upon the bolt members 67, washers 72 being interposed between the sleeves 69 and the boxes or sockets 66. Thesecntters are rotated only by contact with the stalks of cane which they are designed to sever, and said stalks will readily be severed at the desired height from the ground without splitting or tearing.

Suitably supported upon the rear part of the frame is a carrier or. conveyer including an inclined conveyer-trough 73, having bearings near its upper and lower ends for shafts 74 and 75, cooperating to support a suitablyconstructed endless carrier 76, which is driven by means to be resently described.

The rear end of the ame of the improved machine is supported upon an axle which is mounted for rotation and which has carrying-wheels 78, the rims of which are provided in the usual manner with earth-engaging lugs 79. The'axle has a loose clutch member 80, formed with a sprocket 81, which is connected by a chain 82 with a sprocket 83 u on the driven main shaft 30. The axle a so carries a slidable sprocket member 84,

if preferred, provided suitably keyed thereon and operable by means of a shipping-lever 85 to throw the axle 77 into and out of gear with the driving mechanism. The axle is provided with a spur-wheel 86, meshing with a spur-wheel 87 upon the shaft 75 of the carrier or conveyer, to which motion may be in this manner transmitted.

The front end of the frame is sup orted' by means of carrying-wheels 87, whicii are connected by knuckle-joints 88 with stub-axles 89, securely connected with and supported by the side members 1 1 of the frame. .The steering-knuckles are connected, as by linkrods 90, with the ends of a lever 91, supported upon the rear end of the framein a osition convenient to the operator, a hand e 92 being provided for the manipulation of the steering-gear.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advanta 'es of this improved machine will be read' y understood. The machine is not but all the o erative parts of the machine are driven by the single motor supported upon the rear end of the frame. The parts of the device being automatic in action do not re quire constant attention, and the services of but one man are necessary for the purpose of operating the-machine successfully. As the machine passes over the round the strippers will operate to strip 't e leaves from the stalks, and the latter will be moved by the pulling-arms carried by the endless chains 21 into engagement with the floating cutter-carryin head, which by contact with the stalks will e automatically adjusted to the roper position-to sever the tops from the stalks, the

. tops as Well as the leaves dropping upon the ground. The stalks presently become enaged by the rotary cuttin -disks 71, where.- %y they. are severed and su ered to drop .upon

ried to the point of discharge.
