Application tiled June 11,1900. Serial No. 19.860. .No model-l To (LZZ whom, 11a/Ly concern:

Be it known that we, OLE OLSEN and HAG- BART EvENsoN, citizens of the United States, residing at Belview, in the county of Redwood and State of Minnesota, have invented certain new and useful Improvementsin Corn- Planters; and we 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 it appertains to make and use the same. A

Our invention has for its object to provide an improved corn-planter; and to this end it consists of the novel devices and combinations of devices hereinafter described, and defined in the claims.

The invention isillustrated in the accompanyingdrawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a plan View of the improved machine, some parts being removed. Fig. 2 is a rear elevation of the machine. Fig. 3 is a side elevation of the same. Fig. 4: is a vertical section approximately on the line fc4 m4 otl Fig. 1. Fig. 5 is a detail, on an enlarged scale, in section on the line @c5 x5 Vof Fig. 1. Fig. 6 is a similar view to Fig. 5, but in section on the line m6 x6 of Fig. l, some parts being broken away. Fig. 7 is a horizontal section on the line @c7 :1:7 of Fig. 5. Fig. 8 is a bottom plan View of one of the shoes. Fig. 9 is a plan view of one ot' the seed-magazines, the cover thereof being removed. Fig. 10 is a horizontal section approximately on the line w10 m10 of Fig. 6, and Fig. 11 is a horizontal section taken approximately on the line mum of Fig. 9.

The machine or wheel frame 1 is pivotally mounted by means of bearings 2 on a driving axle or shaft 3, on the ends of which the traction-wheels 4 are mounted, being preferably connected therewith by pawl and clutch driving devices. (Not shown, but of any ordinary construction.) The forwardly-projected portions or beams oi"A the main frame 1 are pivotally connected by brackets 5 to the forward or intermediate portion of a transversely extended supplemental or runner frame 6. The supplemental or run-ner frame 6 is provided with a pole 7, which is rigidly connected to the intermediate portion thereof, as best shown in Fig. 1.

The planting-shoes, to be hereinafter described, are mounted on or connected to the supplemental frame 6, and to raise and lower the said supplemental frame, together With the part-s carried thereby, a lifting-lever 8 is pivoted, as shown, to the rearwardly-projected end oi' the pole 7 and to a lock-segment 9 by means of a pin or stud 10. The liftinglever 8 is provided with a hand operated latch 11 for cooperation with the lock-segment 9, and the lower end of the said lever is pivotally connected to the main frame 1, as shown, by a link and eye l2. (See particularly Figs. 1 and 4.) As the outer end of the pole will be supported bythe draft-animals When the machine is in operation, it is evident that the supplemental frame may be raised and lowered and held in different vertical positions by means of the latch-levers 8 11 and lock-segment 9.

The dri vers seat 13 is shown as supported from the rear portion of the main frame 1. To keep the peripheries of the traction-wheels clean, Scrapers 14 on a common shaft 15, mounted in the main frame 1, are provided. A spring 16, connected at one end to the main' frame 1 and at its other end to a short arm 17 of the shaft 15, normally holds the Scrapers in contact with the Wheels 4.- Another arm 1S on the shaft 15 is connected by a link 19 to a foot-lever 20, pivoted at 21 to one side of the mainframe, with its upper end in position to be engaged by thefoot of the driver seated on the seat 13. By pressing on the upper end of the lever 20 with the footv the Scrapers 14 may be thrown into inoperative positions.

The marking devices (one at each side of the machine) are connected one to each end of the supplemental frame 6, and as these parts, as Well as the cooperating planting devices, are in duplicate they will be described in the singular. A long counter-shaft 22 is mounted in suitable bearings in the supplemental frame 6, with its ends termin-ated approximately at the ends ofthe said frame 6.

This shaft receives its motion from a sprocket chain 23, which runs over a driven sprocket. 24 on the said shaft 22 and over a drivingsprocket 25 on the driving-axle 3. The driving-sprocket 25 is loose on the `shaft 3 and is provided with a half-clutch 26, with which a IOO coperating half-clutch 27, mounted to slide on but to rot-ate with the shaft 3, cooperates. A spring 28 puts the half-clutch 27 under strain to engage the half-clutch 26. The sliding half-clutch 27 is adapted to be moved and held in eit-her an operative or an inoperative position bya latch-lever 29, pivoted to a latchseginent 30, which in turn is rigidly secured to the main frame l.

Of the parts'of each marking device the numeral 31 indicates an approximately V- shaped frame which is hinged at 32 to the adjacent end of the supplemental frame 6.

33 indicates a shaft journaled iu the outer portion of theframe 3l and hinged to the adjacent end of the driven shaft 22 by a knuckle-joint 34, which is located in transverse line with the pivots 32 of the said frame 31,

so as to permit said frame 31 to be raised.

while the machine is in action. At its outer end the shaft 33 is provided with a wheel 35 and with a radially-projected marker 36.

To enable the operator from his seat to raise and lower the marking devices, or either block 49.

of them, at will, a latch-lever 37 and coperating latch-segment 38 is provided at each side of the machine, and each lever is connected by a cord or flexible connection 39 to the outer end of the cooperating frame 31. The cord 39 is passed over a guide-sheave 40 on the main frame 1 and overa guide-sheave 42 on the upper end of an arm 43, pivoted to the supplemental frame 6 at 44. The outward movement of the arm 43 is limited by the stop 45 on the supplemental frame. For a purpose to be hereinafter noted the lever 43 will be moved inward when the frame 33 is raised, and to accomplish this a cord or connection 39 is provided with a stop 46, which when the frame 33 is raised, .as shown at the left in Fig. 2, positively forces thesaid arm 43 inward. f

A planting-shoe with coperating planting mechanism is, as already indicated, located at each side of the machine. Such plantingshoe 47 works just outside of the tractionwheel at that side of the machine and is pivoted to the forward portion of the supplemental frame 6, as shown at 48. The rear portion of the shoe 47 is divided or flanged and provided with a transversely-extended spacing-block 49 and with a hollow verticallyextended feed leg or spout 50, the lower end of which opens at or just above the inclined rear portion of the block 49. A cut-off blade or dropper 51 is pivoted between the rear flanges of the shoe 47 for' coperation with the Alink 52 connects the upper portion of the blade 51 to the lower end of a triplever 53, which is pivoted between the sides of the shoe and is subject to a spring 54, connecked thereto and to a drag-bar 55, one end of which is secured to the side of the shoe 47 and the other end of which is pivoted to the supplemental frame 6, in line with the shoepivots 48. Preferably there are two bars 55 for each shoe, so arranged as to prevent un- `purpose to be hereinafter noted.

4 due lateral movements of the said shoe. The

spring 54 tends to hold the cut-off blade 51 in its closed position, (indicated at Fig. 5,) in which position it coperates with the block 49 and the sides of the vshoe to hold the kernels of corn dropped through the leg 50.

Just above the shoe 47 the shaft 22 is provided with a crank' portion 56, one side of which crank has a cam extension 57, for a Working on the crank portion 56 is a box or bearing 58, which is mounted to slide between the prongs of a bifurcated link 59, the lower end of which is pivoted between the sides of the shoe 47. A spring 60 is compressed between the box 58 and the lower end of the link 59, tending to force the box upward, or, rather, Y

thelink downward. A pin 6l, passed through the upper ends of the prong of the link 59, limits the downward movement of said link, and hence of said shoe 47.

The shoe above described is normally carried above the ground; but at each hill to be planted it is forced downward and into the ground by the movement of the crank 56. While the shoe is forced into the ground, shown in Fig. 6, the cam projection 57 strikes the upper end of the trip-arm 53, and through the connection 52 moves the cut-off blade 5l into its open position, (indicated in Fig. 6,) and thus drops the corn previously held thereby, as shown in Fig. 5.

Secured by a shelf or bracket 62 on the supplemental frame 6, immediately over the cooperating shoe 47, is a seed magazine or receptacle 63, provided with a disk or rotary bottom 64 and preferably, also, with a lid 65. The rotary bottom has aplurality of perforavtions 66, which are adapted to be brought successivelyinto registration with a perforation 67 in the bottom of the shelf 62, immediately above the upper end of the shoe-leg 50. As shown, a sleeve 68, secured to the bottom of the shelf 62, surrounds the said perforation 67 and is adapted to telescope into said shoe-leg 50 when the shoe is raised, as shown in Fig. 5. The seed-magazine 63 is provided with an inwardly-projecting segmental section 69, formed with an upwardlybulged channel 70, which overlies the particular perforation 66 of the bottom 64, that stands in registration with or in the vicinity of the perforation 67. Within the raised portion 70 is a spring-cam or cut-off 7l, which directs the kernels of corn which may project from the perforation or pocket 66 downward through the line-perforations 66 67. In the construction illustrated the magazine 63 IIO is supported from the shelf 62 by a plurality shelf 62 engages in succession said notches to temporarily hold the rotary bottom with one or the other of its perforations or pockets G6 alined with the perforations 67 in the shelf 62.

A step-by-step movement is given to the rotary bottom under the advance movement of the machine from a segmental gear77, secured on the driven shaft 22. The segmental gear 77 engages intermittently with an intermediate gear 78, suitably journaled on one of the depending sides of the shelf 62, as best shown in Fig. 5. This gear 78 meshes with gear-teeth 79 on the under peripheral portion of the rotary bottom 64. The segmental gear 77 has only enough teeth to cause byits passing engagement with the intermediate gear 78 the rotary bottom (54 to move the angular distance between its perforations or pockets 66, and this movement is arranged to take place while the shoe 47 and leg 50 are raised, as shown in Fig. 5, at which time the kernels of corn required for one hill are dropped through the leg 50 onto the block 49 and cutoff blade 5l, from whence, as already stated, they will be deposited in the ground while the said shoe is forced downward, as indicated in Fig. 6.

The action of the marking device or checkrow marker will be readily understood by all persons familiar with this class of mechanism. It is, however, evident that the marker on but one side of the machine will be used at one time. I-Ience that mechanism on the inoperative side of the machine should loe elevated and remain idle.

The outer ends of the shaft 22 instead of being rigid are loosely connected, as shown at 8O in Fig. 2, the sections being connected by half-clutches 8l 82, mounted to rotatewith their respective sections and the former to slide on the loose outer section 22L to and from engagement with the cooperating halfclutch 82. A spring 83 tends to hold the halfclutch 8l in engagement with the half-clutch 82; but the said half-clutch 82 is adapted to be moved into an inoperative position by the oscillation of a rock-shaft or rod 84, mounted in suitable bearings 85 on the supplemental frame 6 and provided with a semicircular depending crank-section 86, as shown in Figs. l and 2, which engages a groove 87 in the said half clutch 8l. The above releasing movement of the rock-shaft 84 is automatically produced when the marking-wheel is` raised, as indicated in Fig. 2 and as already described, by the engagement of the arm 43 with a vertical projection 88 at the rear end of the said rock-shaft 84. The action of the machine as a check-row planter should be understood from the foregoing description. The machine is, however, capable of use for planting fodder-corn, in which case the corn should be planted in rows having very closelyspaced hills. For this latter operation a supplemental segment 89 is applied to the segmental gear 77, as indicated by dotted lines in Fig. 5. As shown, this supplemental gearsection 89 has two groups of teeth, which, with the teeth of the gear 77, make a gear having three groups of teeth adapted to move the ro'tary bottom of theseed-magazine three steps of movement for each rotation of the shaft 22. In this action the link 59 should be rendered inoperative, which may be done by disconnecting it from the crank 56 by removing the pin 6I. Then by means of a brace 90 (indicated by dotted lines in Fig. 6) and applied between the shoes 47 'and the downturned sides of the shell' 62 the said shoe is.

held downward, so that it will form a continuous furrow. Also by means of a pin 91, passed through the cut-`oif blade 5l, back of the shoe 47, or by some other suitable device, the said blade 5l is held open against the action of its spring 54, as indicated in Fig. 6. rlhese adjustments having been effected, the machine is adapted for planting fodder-corn.
