CULTIVATOR.

Application filed September 22, 1915.

To all whom it may concern Be it known that I, l/VILLIAM FRED LAMP, a citizen of the United States, and a resident of Mohler, in the county of Lincoln and State of Washington, have invented a new and useful Improvement in Cultivators, of which the following is a specification.

My invention is an improvement in culti vators, and the invention has for its object to provide mechanism of the character specified, wherein the cultivating mechanism is a series of co-ncavo-convex disks arranged with their convex faces upward and each provided with a radial vane on its upper face, the disks being mounted in the same plane on a wheel supported frame and being driven from the wheels of the frame, and being mounted on an auxiliary frame which is adjustable vertically with respect to the main frame, the disks being arranged in a row and spaced apart from each other to permit the rows of plants to move between adjacent disks.

In the drawings :Figure 1 is a top plan view of the cultivator, Figs. 2, 3 and 4: are sections on the lines 22, 33 and H respectively, of Fig. 1, Fig. 5 is a section on the line 5-5 of Fig. 4:, Fig. 6 is a perspective view of one of the cultivating tools, Fig. 7 is a perspective view of one of the bearings, and Fig. 8 is a perspective view of one of the adjusting racks.

The present embodiment of the invention comprises a substantially rectangular frame consisting of front and rear members 1 and 2, and end members 3 connecting the front and rear members 1 and 2. A tongue 4: is arranged transversely of the front and rear members at the center of the frame, and an axle 5 is journaled between the front and rear members at the center of the frame.

Wheels 6 are secured to the ends of the axle outside of the frame and the axle is journaled in bearings 7, which depend from the bars 3. Bevel gears 8 are journaled loosely on the axle near the wheels but inside the frame, and each bevel gear carries a clutch section which is adapted to cooperate with a movable section 9, mounted on the shaft adjacent to the bevel gear, and feathered to the shaft as indicated at 10. These movable clutch sections are operated simultaneously to connect the bevel gears to the axle or to disconnect them therefrom by means of a lever 11. This lever 11 is provided with a laterally extending journal Specification of Letters Patent.

pin 12, which is journaled in a bearing 13 on the tongue. The lower end of the lever engages one of the arms 1 1 of a three-armed rock lever, which is pivoted to a bracket 13 on a bearing block 16 secured to the under face of the tongue. The other arms 17 and 17 of the lever extend in opposite directions, and the said arms are connected by links or rods 18 with the movable clutch sections 9. Each section has an annular groove and the outer end of each link is engaged in the groove of the adjacent clutch section. It will be obvious that when the lever 11 is swung in one direction it will simultaneously move the clutch sections toward each other and out of engagement with the fixed section on the adjacent bevel gear 8, while when the lever moves in the opposite direction, it will move the clutch sections away from each other toward the bevel gears and will connect them to the clutch section. Each bevel gear 8 meshes with a bevel gear 19 on a vertical shaft 20, which is journaled in a bearing 21 on the adjacent end bar 3. The upper end of each of the vertical shafts 20 is provided with a sprocket wheel 22.

An auxiliary frame is supported below the main frame, the auxiliary frame comprising front and rear members 23 and connecting cross members 24 and bearings 25 are secured to the members of the frame at regular intervals by means of clips 26. The bearings are on the inner faces of the members 23 and 24, and each bearing 25 contains a bushing 27. It will be noted from an inspection of Fig. 7 that the bearings 25 are sectional, and that they are square in cross section. Each of the bushings 27 is also sectional, having an external polygonal cross section and an internal circular section. The outer section of each bearing 25 has a lateral extension 28 at its lower end, and these extensions as shown in Figs. 2, 3 and 4: engage beneath the adjacent bars of the auxiliary frame. It will be noted that the frames are composed of angle material, each member of the frame consisting of a horizontal and a vertical portion, and the horizontal portion is arranged at the outer side of the vertical portion and at the lower edge of the same.

The outer section of each bearing 25 is provided above the extension 28 with-a pair of vertically spaced laterally extending pins 29 and these pins engage openings in the vertical portions of the frame members.

The inner section of each bearing 25 'is grooved transversely as shown at 30 in Fig."

7 to receive the clips 26.-

A shaft 31 is journaled in the bushing 27 of each of the bearings 25 and in an upper bearing 32 connected with the upper or main frame and in register with the bearing 25. Each of these bearings 32 is similar to the bearing 25 before mentioned, being sectional and having the extension 33 from the outer section, and having the pins 3+: for engaging the openings in the frame members 12 and 3.

The upper bearings are held to the frame members by clips 35, corresponding in character and arrangement to the clips 26. Each of the clips 26 and 35 is passed around. the adjacent bearing or 32, and the ends are passed through openings in the vertical portion of the frame members and are. engaged by nuts The pins 29 and 34 prevent displacement of the bearings and assist in centering the same. Each of the bearings 32 has a sectional bushing 36, and each shaft 31 fits at its upper end in a sleeve 37, which is integral with a sprocket wheel 38, and extends axially therefrom. Keys 38 are arranged in registering key-ways in the shaft and in the sleeve to constrain the sleeve to turn with the shaft, but the shaft may move longitudinally with respect to the sleeve. Each sleeve 37 and shaft31 constitutes a telescoping shaft, the inner member being the shaft 31 and the outer member the sleeve 37. The sprocket wheels 38 are held at the same level and at'the level of the wheels 22 before mentioned, that is, all the sprocket wheels 38 and 22 are in the same horizontal plane, and an endless sprocket chain 39 is supported by the sprocket wheels, and constrains them to move together. This chain 39 engages every sprocket wheel 38 and in addition engages the sprocket wheels 22 and is driven by the said wheels 22 to rotate all of the shafts 31. Each of the shafts 31 has secured to its lower end a concavo-convex disk 40, and the disks 40 are arranged with their convex faces upward. Each disk is provided on its convex or upper face with a radial vane 41. Each vane is segmental in shape, and is provided with a lateral flange 42 at its straight edge which is lapped upon the disk, and is secured thereto by rivets or the like.

The shafts 31 are constrained to move with the auxiliary frame 23-24 by means of fixed collars 43 on the shafts. These collars are arranged above and below the bearings 25, and it will be evident that when the frame is moved vertically, the shafts 31 and the disks 40 must move with the frame. The auxiliary frame is moved by means of shafts 44. These shafts are arranged at the ends of the frame on the inner sides of the frame members 3, and. they are journaled in bearings 15 on bearing blocks'46, secured to the vertical portions of the end members 3 of the main frame.

A pair of gear wheels 47 is secured to each shaft 44: outside of the bearings 45, and each of the gear wheels il-7 engages a rack bar 48, secured to the auxiliary frame. Each of the rack bars is secured to the vertical portion of the adjacent end member 21 of the auxiliary frame and each rack bar meshes with the adjacent pinion. The shafts 44 are oscillated in unison from a shaft 19, which; is journaled longitudinally of the frame in the end members and in the tongue. This shaft i9 is connected to each of the shafts H by a bevel gear connection 50, and the shaft 19 is oscillated by means of a lever 51. The lever is rigid at its lower end with the shaft and it is provided with latch mechanism sector 53 secured to the rear cross member 2. By means of the lever the shaft may be oscillated to rotate the shafts 41. 1- and when these shafts are rotated the rack bars will be moved upward or downward, depending upon the direction of rotation of the shaft 11-9.

A seat 5 1 may be connected with the main frame if desired, the seat being shown in dotted lines in Figs. land l. A double-tree 55 may be connected with the tongue to permit the attachment of draft animals to the cultivator.

In operation, the auxiliary frame is adj usted by means of the lever 51 to cause the disks 40 to enter the ground at the desired depth. lVhen the machine now is driven forward with the clutch sections 9 in mesh with the fixed sections of the bevel gears i it will be evident that the shafts 22 will be rotated and they will drive the chain 39, which in turn will drive the sprocket wheels 38, and the shafts 31 will be rotated through the key connection 38. As the disks -10 are rotated they will cut beneath the surface of the ground and the vanes 42 will stir the ground as indicated in Figs. 2 and L. The weeds, grass and the like will be cut beneath the surface of the ground and the vane will dislodge them and will cover the weeds, grass, and the like, with earth. The shafts 31 and the disks 4.0 are spaced apart from each other to permit the passage of a row of plants without being damaged by the action of the disks.

The cultivator shown is provided with five disks, and it will be obvious that four rows of corn may be cultivated simultaneously with a single machine. \Vhen it is desired to adjust the disks it is only necessary to swing the shaft 51 in the proper di rection. During transportation on the road, the disks may be lifted out of contact with the ground.

It will be noted from an inspection of the drawing that two series of disks is provided,

52, which cooperates with a toothed o a front series and a rear series, and that the members of the series register.
