ROLLING-DISK 'CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 769,822, dated September 13, 1904,

Application filed April 18, 1904, Serial No. 203,729. (No model.)

To a. whom, it may concern.-

Be it known that I, HENRY BRUCE FURR, a citizen of the United States, residing at Day-' ton, in the county of Lasalle and State of Illinois, have invented certain new and useful Improvements in Rolling-Disk Cultivators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to rolling-disk cultivators.

The object of the invention is to provide a machine of this character whereby the soil may be cultivated to a greater or less degree, as circumstances may require, and to provide means whereby the position or direction of the disks may be changed while the machine is in motion.

A further object is to provide means whereby the disks may be raised and lowered to regulate the cut of the same and to raise them above the ground.

WVith these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation of the machine constructed in accordance with the invention. Fig. 2 is a top plan view of the same. Fig. 3 is a rear view. Fig. 4 is a detail vertical transverse sectional view on the line i i of Fig. 1. Fig. 5 is a horizontal sectional view, taken above beams. Fig. 6 is a detail view similar to Fig. 4:, showing a modified construction of the parts shown in that figure. Fig. 7 is a detail sectional view of the lower end of a diskstandard, showing a modified means for connecting the hub of the disks to said standard. Fig. 8 is a detail horizontal sectional View showing a double hub arranged on the lower end of a standard, whereby two disks may be carried by one standard. Fig. 9 is a detail vertical sectional view of the lower end of a standard and a disk-hub, showing the manner in which the same may be lubricated.

Referring more particularly to the drawings, 1 denotes a main frame, consisting of longitudinal side bars 2, the forward ends of which are secured to bars 3, which converge and are bolted to the inner end of a tongue 4:. The rear ends of the side bars are connected by a cross-bar 5, on which is mounted the drivers and operators seat 6. The rear ends of the converging bars3 are bent inwardly at an angle to the front portions thereof, and to said rear ends is bolted a cross-bar 7, which extends between the side bars 2. To the cross-bar 7 are bolted downwardly-projecting brackets 8, in which are secured the upper horizontal portions. of right-angularly bent axles 9, on the lower ends of which are formed spindles on which are journaled the supporting-wheels 10. Suitable brace-bars 12 extend from the lower or spindle end of the axle to the frame 1 to securely brace and hold the axles against movement. On the inner end of the tongue 4 is secured an upwardly-projecting bracket 13, in which is pivoted a doubletree 14, to the ends of which are pivoted short depending rods 15, to the lower ends of which are connected draft-chains 16, which pass under grooved pulleys 17, journaled in hangers 18, secured to the outer ends of a transversely-disposed bracket 19, which is secured to the under side of the tongue 1. On the ends of the draft-chains 16 are connected swingletrees 20.

Arranged beneath the frame 1 are a pair of disk-supporting beams 21, which are adjustably secured to the lower ends of front and rear arched bars 22 and 23, the lower ends of which are bent outwardly at right angles and pass through clips 24, secured to the beams 21. Set-screws 25 are screwed through the clips 24 and engage the bent ends of the arches and hold the beams in their adjusted positions thereon. The front arched bar 22 is secured directly to the forward ends of the beams; but the rear arched bar is secured to rearward extensions 26 of the beams, as shown.

The beams 21 are preferably in the form of an obtuse angle, and each consists of upper and lower fiat parallel bars which are connected thereon a beveled pinion 39.

together and spaced apart by bolts 27, on which are arranged sleeves 28. The forward ends. of the beams are pivotally connected to the lower ends of upwardly and forwardly curved bars or arms 28, which are connected at their upper ends to the ends of a yoke 29, which has at its forward end a universal-joint connection with an adjustable head 30, which is slidably mounted on an upright post or bar 31, secured at its upper end to the lower side of the tongue 4 and at its lower end to a bracket 32, which is bolted to the lower side of the tongue and to a transverse bar 33, secured between the converging bars 3 in rear of the inner end of the tongue 4.

The head 30 consists of upper and lower blocks 34, having formed in their meeting faces at the rear end sockets 35, which are adapted to receive the ball member 36 of the joint which is secured on the yoke 29. The forward portions of the blocks are provided with vertical alined holes, by which they areslidingly engaged with the post or standard 31. The blocks 34 are held together on the post by a clip 37, on the forward side of which is formed a lug or nut having a verticallydisposed threaded aperture which is engaged with a vertically-disposed threaded rod or bolt 38, the upper end of which passes loosely through a hole in the tongue 4 and has fixed The lower end of the rod passes through the bracket 32 and has on its lower end a retaining nut 40. Meshing with the pinion 39 is a similar pinion 41, fixed on the end of a rearwardly-extending inclined rod 42, the forward end of which is journaled in a bracket 43, secured to the tongue, and the rear end of which is suitably supported and provided with a crankhandle 44. Upon the turning of the crankrod 42 the threaded rod or bolt 39 will be turned, which will cause the head 30 to be moved up or down upon the post or standard 31, and thereby raise or lower the forward end of the beams through the yoke 29 and curved bars 28, which connect this end of the beams 21 with the head 30.

In the forward end of each beam is journaled a downwardly-projecting vertical standard 45. In rear of the standards 45 are arranged similar standards 46, the upper ends of which are journaled in brackets which pro ject laterally from the outer sides of each of the beams. Back of the standards46' are arranged other standards 47, which are journaled in the beams 21. The standards 47 are similar to the first-mentioned standards except that they project to a considerable distance above the beams, as shown. In the rear ends of the beams are journaled still another pair of standards 48, which are of the same construction as the standards 45 and 46.

On the lower ends of each of the standards 45, 46, 47, and 48 is fixed a horizontal bearing or support 49, in each of which is journaled a revolving disk 50. These disks are arranged on the inner sides of the standards and bearings 49 and are preferably flat, having their outer edges beveled to an edge,as shown. On each of the standards 47 are arranged upper and lower coiled springs 51 and 52, and on the upper ends of the standards are fixed crankarms 53, which retain the springs in place. Above the standards 47 is arranged a curved bar 54, to which are fixed downwardly-projecting brackets 55, having forwardly-projecting right-angularly bent lugs 56, in which are formed openings through which are adapted to pass the upwardly-extended ends of the standards 47. The lugs 56 engage said standards between the upper and lower coiled springs 51 and 52, as shown.

The curved bar 54 is slidably' supported by hangers 57, which consist of inverted Tshaped plates 58, arranged on one side of the bar, and on said plates are rotatably mounted an upper grooved roller 59, which engages the upper edge of the bar 54, and two grooved rollers 60, which engage the lower edge of the bar, which connection permits said bar to slide laterally in either direction. To the upper ends of the hanger-plates 58 are loosely connected links 61, the upper ends of which are connected to the forward ends of hand-levers 62, pivotally connected to the standard 63 of segmental rack-bars 64, which are mounted on and securely braced to the cross-bar 7 of the main frame. The segmental rack-bars 64 are further braced and connected together by a cross-bar 65, whichrotatably supports the rear end of the inclined crank-rod 42. The hand-levers 62 are provided with retainingpawls 66, which engage the rack-bars 64 and hold said levers intheir adjusted positions. The bar 54 yieldingly supports the rear ends of the beams 21 through the brackets 55, which engage the same between the springs 51 and 52. Upon the operation of the handlevers said rear ends may be raised and lowered, as will be understood.

To each of the standards 45, 46, 47, and 48, between the upper and lower bars of the beams 21, are respectively connected crank- arms 67, 68, 69, and 70. v The crank-arms 67 and 68 of the standards 45 and 46 are respectively connected to the crank-arms 69 of the standard IIO 47 by links 71 and 72, while the crank-arm 7O which is pivotally connected a longitudinallydisposed lever 76, the forward end of which is slotted and has a loose pivoted connection with the front arched bar 22. The rear ends of the lever 76 is adapted to slide on the rear arch 23 and is connected to a cable 77, which extends laterally in each direction and passes downwardly over grooved guide-pulleys 78, journaled on the rear side of the rear arch 23. The lower ends of the cable 7 7 are adjustably connected to foot-levers 79, the forward ends of-which are pivotally connected to the sides of the front arched bar 22. The levers 7 9 are bent or curved laterally for a short distance to avoid interference with other parts of the machine, and the outer ends of the same pass through a guideway formed by the sides of the rear arched bar 23 and a rod or bar 80, arranged adjacent to and secured at its upper and lower ends to said sides. By depressing one or the other of the foot-levers the lever 76 will be actuated to cause the bar 7 5 to turn the crank-arms 53 and the standards 47, and through which motion will be imparted to the other standards to turn the disks carried thereby in one direction or the other to cause the soil to be thrown toward or from the corn.

In Fig. 6 of the drawings is shown a modified construction of the hangers 57 and the parts connected thereto. In this instance a hanger 81 is provided, said hanger having two pairs of grooved rollers 82 and 83, the former being arranged below, the latter above, a round. bar 84, which is adapted to take the place of the bar 54 (shown in the other figures) and is curved to correspond with said bar 54. -Below the bar 84- and spaced from the same is arranged a parallel bar 85, the ends of which are bent upwardly and secured to the ends of the bar 84. To the bar 85 is loosely connected, as by pairs of short links 86, the upper ends of downwardlyextending bars 87, which take the place of the brackets 55 and are provided at their lower ends with right-angularly bent apertured lugs 88, through which are adapted to pass the upper ends of the standards 47, as shown and described in connection with the lugs 56 on the brackets 55. The hangers 81 have each pivotally connected thereto the lower ends of a link 89,- the upper ends of which are bifurcated, as shown, and are adapted to be pivotally connected to the operatinghandles 62 to take the place of the links 61.

In Fig. 7 of the drawings is shown a detail vertical sectional View of the lower end of a disk-standard illustrating a modified construction of bearing for the disk-hubs. In

this instance instead of the lower end of the standard and the bearing being cast in one piece said lower end of the standard is split upwardly a short distance, and said split ends are then bent laterally, as at 90, to form the upper portion of the bearing and laterallyprojecting ears or lugs 91, to which are bolted the laterally-projecting ears or lugs 92 of a casting 93, forming the lower part of the hearing.

In Fig. 8 is shown a double form of hub 94, by which two disks may be mounted on the lower end of a standard, it being sometimes desirable to use this arrangement of disks on the two outer or rear standards 48. In this form of hub the two disks mounted thereon are disposed at an angle to each other, with their forward edges touching.

In Fig. 9 is shown an arrangement which may, if desired, be applied to the disk-standards, whereby the bearings on the lower ends of the same may be lubricated. This arrangement consistsin providing hollow or tubular standards closed at their upper ends by a threaded plug 91. Within the standards is disposed a plunger or piston disk 92, having a threadedaperture 93, said disk being mounted on a threaded rod 94, which projects down into the tubular standard and is screwed through the threaded aperture of the plunger-disk 92. The upper end of the rod 94 passes through an aperture in the plug 91 and is provided above and below said plug with stop-pins 95, whereby the rod is held from vertical movement, but is permitted to turn freely in the plug. On the upper end of the rod 94 may be formed a suitable handle for turning the same. The plunger-disk 92 isprovided on one edge with a notch 96,- which is adapted to engage a vertically-disposed rib 97, formed on the inner wall of the tubular standard, thereby preventing said disk from turning with the rod, but permitting the same to be screwed up or down by reason of its threaded engagement with the rod. In the tubular standard below the plunger-disk is placed grease or other suitable lubricant, which when the plunger-disk is screwed down will force said lubricant through a feed-opening 98 in the hub of the disk, and thereby lubricate the same.

In the drawings each beam 21 is shown as having mounted therein four disk-standards. I do not, however, wish to confine myself to this number, as it is obvious that the length of the beams may be increased and any desired number of disk-standards arranged therein, the same number being arranged in each beam.

I do not desire to limit myself to the use of my improved devices hereinbefore described in connection with a wheel-cultivator, as the same may be also used in connection with a walking-cultivator.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion,

' and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
