To ZZ whom z' may concern.'y

Be it knownthat I, HORACE B. VVORLEY,

a citizen of the United States, residing at Lake Arthur, in the county of Chaves and -State ofv New Mexico, have invented new and useful Improvements in Kafir-Corn Headers, of which the following is a speciiication'.

This invention relates to machines for heading` Kair corn, maize, cane and the like, and it has for its object to produce a machine of this class of simple and improved construction whereby the operation of heading may be expeditiously performed in a labor saving manner.

A further object of the invention is to produce a machine of the class described which in a simple and convenient manner may bel adjusted to operate on stalks of different heights.

A further object 0f the invention is to produce a machine of the class described having means whereby the detached heads may be loaded into a receptacle. i

lVith these and other endsy in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter' fully described and particularly pointed out in the claims.

In'the 'accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details thereinv exhibited, but that changes, alterationsand modifications within the scope of the claims may be resorted to when desired.

Corresponding parts in the several iigures of the drawings are denoted by like characters of reference.

The axle of the improved machine comprises an arch 15 having spindles 16, 17 extending from the limbs thereof, said spindles carrying` the ground wheels 18, 19. Supported on the spindles adjacent to the limbs of the axle arch are boxes 2O each having" a forwardly extending arm 21, said boxes being connected together by'a yoke or'arch 22 that extends rearwardly with respect to the axle arch 15 and the particular use of which will be hereinafter" set forth. TheV spindle 16 extends materially beyond the' outer face of the ground wheel 1,8"a'nd uponthe projecting end of the spindle is pivot ally mounted the tongue 23.

The gatherers G are each composed of an upper and a lower member 24, 25, said members converging in a forward direction, being suit-ably secured together at their for# ward extremities while their rearward ends are spaced apart by spacing members 26. The gathering members are also tapered inv a forwarddirection, being beveled on their inner faces to facilitate the admission of stalks therebetween. The gatherers are supported at their rearward ends on a cross bar 27 with which they are suitably connected, but through the greater portion of their length they are spaced apart, being connected together b v arch members 28 se-v cured on the top members 24 of the respective gatherers.` rThe top and bottom memV` bers of the respective gatherers are provided with bearings wherein shafts 29, 30 are supported for rotation, said shafts be# ing` supported adjacent to the inner edges of the top and bottom' members ofthev gath-v erers. The shafts 29 are disposed inter! mediate the front and rear ends and' the sh'afts'30 nearthe rearward ends of the respective gatherers. Trained over the shafts' 29, 30 of each gatherer is a chain conveyer 31 some of the links of which are provided with prongs 32 adapted to engage the corn stalks for the purposeof feeding the same' rearv'va'rdly'vv between the gatherers'. The

rearwardvshafts 30 are extended abovev the top members 24 of the" respective',gatherers,I

one-'of said shafts being provided' with` a" sprrekstf wheel smiA the other' winl-y gear wheel 34, the latter meshing with the gear wheel on an idler shaft 36, the latter being also provided with a sprocket wheel 37 lying in the plane :ofthe sprocket wheel 33 for the purpose of receiving mo@ tion and transmitting such motion inthe proper direction to the shafts 30 by means toy be presently described. The gatherers G are connected with the spindlesVv 16, 17 by means ot braces 38, said braces having boxes engaging the spindles and capable of turning freely thereon. Said gatherers are also provided on'the lower faces of their bottom members 25 with lugs 39 which are connected by links 40 with the forwardly eX- tending arms .21 of the boxes 20. The braces 38, it may be stated, are preferably connected with theV gatherers by pivot members 41. .Additional bracing andsupporting members may be provided, one such member 42 being mounted at one end on one of the pivots 41 and having its other end securely connected with the tongue 23.

Secured on the ground wheel 18, which also constitutes a bull wheel or tractionl wheel, is a clutch member C comprising a disk 43 and a sleeve 44, the latter surv rounding the spindle. The spindle also carof thespring 49, thereby disengaging it' from the clutch member C, By rocking the.

ries ahub 45 onwhich is mounted a bevel gear 46 and a sprocket wheel 47, said hub having also a clutch member 48 matingv with the clutch member C inthe direction of which the hub is normally pressed' by the action of a spring 49, one end of which abuts on the hubl 45 while the other end of said spring abuts on Voneside member of a frame 50 lwhich ismounted on the spindle, said-,frame being secured by meansot a brace 51 which connects it with the tongue 23. The other side member of the frame 50 has an eye or boxing 52 engaging the sleeve 44 of the clutch member C.. 53 isa lever having a forked head treceiving between the limbs lthereof the sleeve 44 of the clutch member C, and also the clutch end ot the hub 45, said forked head being cam-shaped as shown so that by rocking the lever, which extends rearwardly beneath lthe rear por-l tion of the trame 50, in one direction, the

hubv 45 may be forced against the tension lever in the other direction, the hub will be released and will, Vby the tension of the spring 49, be forcedin engagement with the clutch member'O.I A notched plate 55.

ixed on the under side of the lrearward portion ofthe trame 50, serves to'support the handle portion of. the .lever 53 and also to secure it in adjusted position by` engagement with one ofthe notches 56 in the supporting plate, l

Connected with one limb ot the .adjusting yoke QQ-is a hand lever57 having a stop member or locking device 58V engaging a rack segment 59 which is fixed on the trame 50. By manipulating this lever, the frame 50 may be rocked, causing the forwardly extending arms 2110i the boxes 20 with which the yoke is connected to raise or lower the gathering members through the medium of the links 40, the partsbeing retained in adjusted position by means ofV the lock or stop member 58.

' One of the gatherers G is provided with bearings for a substantially vertical shaftVv 60 which is provided' below the gatherer with a telescopicextensionV 61 for which a suitable bearing 6:2 is provided, said telescopic extension carrying a bevel pinion 63 meshing with the bevel gear-46. The shaft 60 is provided intermediate the top and bottom members of the gatherer G in which it is supported with a crank 641which is con-V nected by a pitman 65 with 'a cutting member 66'supported for reciprocation onV the bottom members of the twogatherrers, and which coperates with a stationary cutting member 67 which is likewise supported on the bottom members of the two gatherersY in the path ot the incoming stalks, the heads ot which willbe severed by the cuttingY apparatuswhen the machine is in operation. Theshatt 60 is extended above-theitop member of the gatherer and carries .a Asprocket wheel 68 from which a chain 69 is trained over the sprocket wheels 33" and V37, thereby driving the chain'conveyers, the cutting apparatus being actuated .by the'rotationY of thefshaft 60 as rwill be readily seen. The tel- 100 escopic downward extension of the lshaft permits the vertical adjustment of the gath'f erers by means of the adjusting lever 57, as e previously described.

VHingedly connected which supports the rearward ends Vof the gatherers, is an elevator 70, the conveyer of which is driven by a suitable transmission including a chain 7l which is trained over the sprocket wheel 47 on'the hub V45. Thello free end of the elevator is supported byv means of a brace bar 72 having its lower end mountedon the spindle 17 andA provided.A near its upper end with a slot 73 for the pasf sage of a bolt 74 that extends from ythe11r5 elevator frame and which is provided with a nut 75 which may be tightened to 'secure the elevator trame in adjusted position. A spring supported tightener Vor j tightening pulley 76 is provided, which constantly en- 120 gages the-transmission chain 71 for the purpose of maintaining said chain under proper tension 4at all adjustments ot the gathering. members. .Y l

From the foregoingr description, takenin 125 connection Vwith the drawings Yhereto fanneXed, the operation and advantages of this invention will bereadilyunderstood. The machine may bedrawnV loya team hitched to' the tongue 23 adjacent to one 'sideglof theage auV soY

machine. The gatherers may be adjusted to elevate down stalks and to guide the same, as well as the standing stalks, between the gatherers where they will be seized upon by the chain conveyers, whereby they will be positively carried in engagement with the cutting apparatus whereby the heads will be severed and thrown on the elevator while the stalks pass beneath the axle arch 15 and the yoke 22. The elevator may be adjusted to discharge into the box of a wagon following the machine, or into a suitable receptacle otherwise provided.
