To all whom it may concern:

vBe it known that I, EDWARD Hover, a

citizen of the United States, residing'at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain; new and useful Improvements in Land- Workersand Seeders; and I do hereby 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 itappertains to make and use the same.

My invention has for its particularobject to provide aneflicient land worker and in the claims.

- cylinder; Fig. 7 is a side elevation of a seeder, and to such ends, the invention consists of the novel devices and combinations of devices hereinafter described and defined In the accompanying drawings, which illustrate the machine in its complete and preferred arrangement, like characters indicate like parts throughout the 'several views.

Referring to the drawings; Figure 1 is a plan view of the improved machine; Fig. 2

is aside elevation of the improved machine,

with one wheel removed and with oneaxle sectioned on the line x w? of Fig. 1; Fig. 3

H p is i detail view in front elevation showing a supplemental supporting frame .for a driven toothed cylinder or shaft, and also parts of one of the said toothed cylinders; Fig. 4 is a section on the line 02 a of Fig. 3; Fig. 5 is aside elevation of one of the toothed driven cylinders; Fig. 6 is a front elevation 'of one of the sections of the said toothed driving cylinder or shaft ahd 8.is a front elevation of one of the sections of the said. driving cylinder.

rectangular metallic structure, having at the front portions of its sides depending guide brackets 2 equippedwith vertical guide channels 3. 'In the guidechannels 3, vertical adjustable rack bars 4 having teeth 5, are mounted; and the lower portions of these rack bars, are; provided with outwardly projecting trunnions 6, on which" the front wheels ,7 are journaled. The upper ends of the rack" bars tare connected by links 8, to crank armsti), of a rockjshaft 10, v

. journaled in suitablebearings of the frame 1, andvprovided at its intermediate portion with" -an upwardljextehded armll. The

/ arm 11 is connected by a rearwardly extended rod 12, to a latch lever 13 that is pivoted to and cooperates with a toothed lock :segment 14 secured on the central portion of the frame 1. As is evident, by manipulation of the lever 13, the front portion of the frame 1 may be raised andlowered in respect to-the front wheels 7 The numeral 15 indicates a pole, having 1 a pole bracket 16 pivotally connected to the frame brackets 2.

The sides of the frame 1 at-their rear ends are provided with downwardly e gztended legs 17; and the rear portion of the machine is supported'by caster wheels 18, having brackets 19 swiveled on the lower ends of the legs 17. i

In this improved machine I employ toothed driving and toothed driven cylinders or shafts, which are arranged for engagement with the ground, the former servcylinders, as well as the toothed driven cylinders, are preferably divided or arranged in longitudinally spaced axially alined pairs or sections. As shown, each toothed driving cylinder comprises a SllitftQO and a multiplicity of fiat radial blades or teeth 21. At

their ends these cylinder shafts 20 are jour-- naled in the outer frame brackets 2 and in similar innerv frame brackets 25*. Each driven toothed cylinder comprisesa shaft 22 and curved teeth or blades 23, the outer ends of which latter are preferably sharp=.

ened and set obliquely so that they will readily cutinto and disintegrate the ground.

The two axiallyalined shafts or shaft sections 22, (see particularly Figs. 2 and I 3), are journaled in depending vouter'and in- The mainframe 1 of the machine is a brackets 21, These shafts 26"are axially alined transversely of the machine; and each carries two sprockets, 28, 29 and one thereof also carries athird sprocket 30. Sprocket chains 31 run over the sprockets 28 and over Y the sprockets 32, secured on the correspondmg shafts 20 of the toothed. driving cylinders. Sprocket chains 33 run over the sprockets-.29 and over sprockets 34 on the,

75 i ing to drive the latter. The to othed driving outer ends of the shafts '22 of the driven toothed cylinders. The said sprocket and chain drives are so arranged that the driven toothed cylinder. will be given about three 5 rotations for each rotation of the driving toothed cylinder.

Mounted i" suitable bearings on the-main frame 1, overlying the sdpplemental frame 24, is a rock shaft 35, provided at its ends with rearwardly extended arms 36, that are connected by links 37 to the upper end portions of the said.supplemeutal frame 24. At its central portion the rock shaft 35 has an upwardly extended arm 38 that is connected bya ink 39 to. a latch equip ed lever: 40 that cotiperates with and is a apted to be held in different ositions by a notched lock segment 41 rigid tral portion of the main framel. Coiled springs 42, (see Fig. 2) carry a part of the weight of the supplemental frame 24,'and

parts mounted thereon, from the sides of the main frame 1. i

. Loosely journaled on the outer ends of th I shafts 20 of the driving tootlied cylinders are spur pinions that mesh with the teeth 5 of the respective vertical movable rack bars 4. Each pinion 42' carries one member 43 of a friction clutch, the other member 44 of .30 which is mounted to slide on and is keyed or otherwise held to. rotate with the said shaft- 20, and is adapted to be moved to and from operative position by a suitable bell.

{of the said bell cranks, for action in oppo- 45 sition' to the springs 47 are attached operating cables or- Wires 48. These cables 48 run over suitable guide sheaves 49 on the frame 1 and are attached to a common operating latch equ p edlever 50 that is adapted to be 50 held III-d1 erent positions by aeoiiperatmg lock segment5l secured to the central poretion of the framework 1. The'drivers seat 52 is suitably applied to the rear central portion of the frame-work 1. 55 The machine so far described is a complete machine operative to-reducethe ground to condition for planting, that is, it will do the work both of a plow and of a hart-0W, and often the machine will be used forsuch purposes only. i

To adaptthe machine to. simultaneously reduce the soil to condition for seeding and to seed the same, seeding adjustments'are provided, and "these, in the preferred form, will nowbe described.

1y secured on the cen A transversely extended seed box 53, such as used in ordinary seeding machines, is secured on the rearwardly extended portion of the main frame 1 andseed feeding devices of ordinary construction, such as customarily used in seeding machines, are arranged to work within the seed box to'deli'ver the seeds to depending spouts. 54, which are device, it is only necessary, for the purpose of this case, tonote the feed shaft 55, which is provided at one end with a sprocket 56, overwhich and-the sprocket 30 on one of the shafts 26, runs a sprocket 57. The sprocket 56 is loose on the feed shaft 55 and is provided with a half clutch 58 that is preferably flexible. ()f the parts of the feed adapted to be engaged by acoiiperating half clutch 59 that is slidably mounted on said shaft 55 and provided with a cam head 60. (See Fig.1.) A coiled spring 61 compressed betweenthe cam head 60 and the adjacent end of the seed box 53 tends to hold the half clutch 59 engaged with the half clutch 58, thereby coupling the sprocket 56 with the shaft55 for rotation therewith.

The seed spouts 54 deliver into the upper ends of seed boots 62, the lower ends of which are adapted to be inserted into the ground, when lowered. These seed boots 62, near'their upper ends, are provided with horizontal bearing sleeves 63, that are independently ivoted on' a horizontal transverse supporting shaft 64, the ends of which are provided with eyes 65 arranged to slide.

vertically upon the legs 17 of the frame 1. The seed boots 62 are yieldingly held in operative positions, by coiled springs 66 attached to the upper ends thereof, as best shown in Fig. 1, and attached to a rearwardly extended bale 67, the arms of which are rigidly secured to the eyes (35 of the. shaft 64. These springs hold the seed boots in operative positions at all times, except when a rock,.roo't or other abnormal obstruction is encountered. At' such times, they will yield and prevent breakage of the machine...

At itsextreme ends the. bootsupporting shaft 64 is connected by links 68 to the crank formed ends 69 of a transverse rock shaft 70 mounted in suitable bearings on the rear portion of the frame 1 and provided at its intermediate portion with an upwardly extended arm 71. This arm 71 is connected by a link 7 2 to the arm 38 ofv the rock shaft 35, so that vertical movements will be imparted to the seed boots 62 from the lever .40 simultaneously with the vertical movements imparted. to the driven toothed cylinders. 'Preferably. the arm 71 isprovided tents of vertical movements may be imparted to the seed boots'undcr predetermined vertical inovementsof the auxiliary frame 24.

A curved shield or dash-board 73 is secured to the upper rear portion of the frame 1 and extends downward between the upper portions of thevseed boots 62 and the upper portion of the driven toothed cylinder, fora purpose which will presently appear.

To close the furrows made by the" seed boots 62, and to pack the ground over the planted seeds, a roller is preferably arranged to travel at the rear of the said seed boots and back of the caster wheels 18. This roller 74 is preferably made up of a multiplicity of sections journaled on a shaft 75, held by a rectangular frame 76, the front edge of which is ivot-ally connected, for both vertical and orizontal movements, to the lower ends of a pair "of coupling brackets 77,

shown as'of triangular form. The upper and forwardly extended ends of the brackets 77 are detachably pivoted at 78 to rearwardly extended forks 7 9 secured to the rear side portions of the frame 1. These pivots 78 permit the brackets 77 to swing laterally when the machine is turning the corner or traveling on a curved line.

It will be noted that the upper end of the right hand link 68 stands in position to engage the oblique surface of the cam lfead 60, so that when the shaft shall have been given approximtely one-half rotation, un-

der advance movements of the machine, the

sliding half clutch 55 will .be disengaged from the half clutch 58 of the loose continuous driven sprocket 56. The purpose accomplished by this construction is to automatically stop the feeding action when the ,seed boots and toothed driven cylinder are raised into in-operative positions and to automati- I cally throw the feed mechanism into action whenever the said seed boots and cylinders are lowered into operative positions: i

The teeth 21 of the driving tpotheditiylinders are adapted to, be simultaneously'low-.

ered into contact with the ground by a forward movement of ,the lever 13, which al lows the forward portion of the main frame 1 'to lower. 'lhevteeth" 21 will not only en gage the ground, but will enter quite, deeply mto' the ground and underforward movement of the machine will cut' and pulverize the ground to a very considerable extent and turn upward'dnore orless thereof! The r.0-

of thesaid driving or 'front-toothd tatio der. positively rotates the driven or rear cylin toothed cylinder at a relatively high speedin the same direction, to-wit: in the direction ofth'earrow marked the eon 'in 'Fig. 2.

By rearward movement of t e lever 40 the. rear or driven toothed cylinder andthe boots 62 may-be lowered into the griiund to the desired extent, This high i'otat-i on of .the driven toothed cylindenwill cut and finely pulverize the ground and leave, the

- samein as good or better conditon than ground that has been well plowed and well harrowed.. The cylinder teeth 23 will throw the pulverized dirt rearward and upward in a fine shower, most of which will-be intercepted by the dash-board 73, but a part of th1s shower of dirt will be thrown rearward under the dash-board and between the seed boots to properly cover the seed deposited in the furrows formed by the said seed boots. By the roller 74, which follows the seed boots, the furrows will be closed and the ground pro'perly packed over the planted seeds.

As is obvious, the rear toothed" cylinder and the seed boots will be simultaneously raised into in-operative positions by a forward movement of the lever 40. When it is desired to raise the front port-ion of the frame 1 from 'its lowered position, the lever 50 is moved rearward so as to simultane-- to the surface of the ground, .after which the further upward movement of the front portion of the said frame 1 and 'of the said front toothed cylinders must be completed by' rearward movementof the lever 13.
