HOE IN G-MA CHINE Application filed November 21, 1907.

T 0 all whom it may concern:

Be it known that I, IVILLIAM A. HARRIS, a citizen of the United States, and a resident of Greenville, in the county of Greenville and State of South Carolina, have invented certain new and useful Improvements in Hoeing-Machines, of which the following is a specification.

My invention is an improvement in hoeing machines, especially designed for chopping cotton, and particularly in that class of such machines illustrated in my former patent No. 873,543 dated Dec. 10, 1907. The present invention relates to means for gaging and regulating the depths of the hoes, means for securing the regulation of the size of the stand left by the hoeing devices, means for shifting the carrier frame laterally along the drive shaft, and other improvements as will be specifically described hereinafter.

In the drawings Figure 1 is a top plan view of a machine embodying my invention. Fig. 2 is a sectional side elevation on about line 22 of Fig. 1. Fig. 3 is a vertical section on about line 3-3 of Fig. 2. Fig. 4 is a detail section on about line 44 of Fig. 2, illustrating the guide in which the front end of the carrier slides laterally. Fig. 5 is a perspective view showing portions of the carrier frame, hoe frame and hoe shaft. Fig. 6 is a detail section on about line 66 of Fig. 1. Fi 7 is a detail section of a part of the revo ving hoe showing the adjustable arms for regulating the size of the bunch or stand, and Fig. 8 is a sectional view illustrating a some- What diflerent construction from that shown in Fig. 7.

In the present machine, I provide a main frame A, to which the tongue may be secured and in which main frame is journaled a drive shaft B, which may be driven in any suitable manner, preferably by means of a wheel B secured thereto, the opposite wheel B being loose on the shaft to facilitate the turning of the machine. On this drive shaft B is pivoted at its rear end a carrier frame C, which frame is slidable along the drive shaft so it and the parts carried thereby may be adjusted to any desired position, and it also rocks on the drive shaft so that one end of the carrier frame and the parts carried thereby may be raised and lowered in the manner more fully described hereinafter. This car rier frame C supports at its rear end the cultivating plows D, the beams F carrying the said parts being pivoted at their front ends in con- Specification of Letters Patent.

Serial No. 403,221.

parts so far described may in general respects be similar to the corresponding parts in the machine described in my former application before referred to.

For adjusting the carrier frame C laterally along the drive shaft, I prefer to provide the said frame with a rack C extending parallel to the drive shaft and engaged by a pinion G on a steering shaft G, journaled in suitable bearings supported from the main frame so the said steering shaft may be turned by its wheel G to adjust the carrier frame laterally to any desired position upon the drive shaft. The rack C is extended at C for engagement by a detent pawl C carried on the main frame and which may be adjusted into engagement with the rack in order to secure the same and the frame 0 in any suitable position upon the drive shaft.

The carrier frame is ivotally and slidably mounted at its rear enff upon the drive shaft and has at its front end a roller C, which operates within a supporting frame C adjustably held at one end C to a slotted bracket C depending from the front bar of the main frame and adjustable at its other end C along a bracket C depending from the front bar of the main frame, and having a plurality of openings C through which the bolt C may be passed in securing the end G of the supporting frame in any suitable adjustment up or down. By this means the carrier frame may be adjusted at its front end to properly level the hoes of the chopper frame, this being especially useful in adapting the machine to the height of the draft animal hitched to the machine, in the practical operation of the invention. The hoeing frame I is pivoted at one edge I on an axis approximately in line with the direction of the motion of the machine, and at its opposite edge has bearings I for the supporting shaft of the chopping hoes.

In pivoting the hoeing frame it is preferred to provide the carrier frame O with a lower forwardly projecting arm C Whose front 5 end is upturned providing the bearing at I for the front end of the hoeing frame I, the pivot at the rear end of the hoeing frame being effected by means of the counte'rshaft J which is ournaled in the hoeing frame and extends at its rear end through the said hoeing frame and into a bearing at T in the car rier frame C. The hoeing frame is provided with an arch P, which extends over the countershaft J, and is provided at its front end with a trunnion I which forms the forward extension of the carrier frame and to which the roller C is journaled, as will be 'understood from the drawings.

The countershaft carries a pinion J and a sprocket wheel J the pinion J being movable along the countershaft and adapted to be secured in any adjustment thereon so it can be set into and out of engagement with any desired rack K, K or K of the gear K, which is keyed to the drive shaft and movable along the same with the carrier frame ,C so it will always be in position to mesh with the rack on the counter-shaft. By this construction the drive shaft through its rack wheel gives motion to the pinion on the countershaft, and the sprocket wheel on the countershaft gives motion by the sprocket chain J 3 to the hoe shaft L which is journaled in the bearings I at the swinging end of the hoeing frame. The hoeing frame swings up and down at its swinging edge and is partially supported at such edge by a spring M connected at its upper end with the upright M on the carrier frame and at its lower end with the swinging end of the hoeing frame so it will aid in supporting the weight of said frame, and a lever M is secured to the hoeing frame and moves along the arc M on the carrier frame, said arc having a stop at its lower end to limit the downward movement of the lever and the hoeing frame and being provided with one or more notches M for engagement by the awl M of the lever in order to hold the hoeing frame up clear of the ground.

The hoeing frame is provided at its front end with a gage wheel N adjustably sup ported in the manner presently described and adapted to limit the extent to which the hoes may operate in the ground. This gage wheel N has an upright N adjustably connected with a bracket N which bracket bl rocks relatively to the hoeing frame so it can be adjusted with respect thereto and may be secured in any suitable adjustment by the clamping devices l As shown the hoeing frame has its front arm provided with a boxing N forming a bearing for the front end of the hoe shaft and secured to the hoeing frame by a clamping device 1 the bushing being extended at its ends to receive the rocking bracket, and a collar l 6 being fitted on the front end of the hoe shaft in advance of the bushing to secure the hoe shaft from endwise adjustment. By the described construction, it will be noticed the bracket may be adjusted relatively to the hoeing frame in order to accommodate the angle of the gage wheel to the angle of the said hoeing frame and the gage wheel may be set up or down to regulate the depth at different angles, as may be desired in the operation of the invention.

By preference the bracket N is mounted midway between its ends on the bushing and supports at its opposite ends the listers O, the upright O of one of the listers being adjustably connected with the standard of the gage wheel and the upright O of the other lister being adjustably connected with the end of the bracket opposite that supporting the gage wheel, the adjustment of the lister standards being effected by the slotting of the same to receive the securing bolts, as shown in the drawings.

The hoes P are supported by their arms P, P, on the hoe shafts and revolve there-' with. The arms P may be in fixed relation and with a uniform space between the hoes of the fixed arms and at intervals preferably two blades of the hoes are adjustable in the direction of revolution so that I may set these adjustable hoes toward and from the adjacent ones. This operation is important as if the hoes were of such length and so spaced apart as to operate when uniformly placed to cut out the entire cotton row, one or more of the hoes might be either advanced or retracted to increase thespace in the direction of revolution between the hoe blades and thus leave a stand of the size corresponding to the extent to which the said blade or blades were advanced or retracted. As shown in Figs. 3 and 7 this is preferably effected by making two of the arms 1 adjustable in the direction of revolution by pivoting them at their inner ends concentrically with the hoe shaft and having them secured between their ends adjustably in connection with the curved bars P slotted at l? to receive the securing bolts P In this construction the two adjustable hoe arms are independent and made adjustable independently. It may, however, be pre ferred to adjust the diametrically opposite hoeing arms jointly, in which event said arms may be integral, as shown in Fig. 8 of the drawings. This is an important feature of my invention, as by it I am able by a slight adjustment of the hoe blades in a circular direction to regulate the size of the stand or bunch left in the row, and this may be accomplished in a simple manner as will be understood from the drawings, and foregoing description. By properly spacing both of the adjustable arms of the hoe, two bunches may be left for each revolution of the hoe, or if it is desired to space the bunches further apart, one hoe may be adjusted equidistantly between its adjacent hoes, and the other properly set to secure the desired size of bunch, or any suitable number of blades of the revolving hoe may be made adjustable, as will be understood.

I claim 1. A revolving hoe having a series of blades and arms supporting the same and rigid with each other and provided with curved slots, blade supporting arms movable relatively to the other arms of the hoe, and bolts extended from said movable arms through the curved slots of the bars for securing the movable arms in different adjustments.
