CHECK-ROW CORN-PLANTER.'

SPECIFICATION forming' part of Letters Patent No. 530,259, dated December 4, 1894.

` Application filed June 14, 1894. Serial No. 514,575. (No model.)

struction of planter,whereby the proper check-l ing and regularity of movement of the planting mechanism may be attained without the use of check-wires or cables.

Further objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed ont in the appended claims.

In thedrawings; Figure 1 vis a perspective view of a check-row corn planter embodying my invention. taken parallel with and in the plane of the axis of the operating-wheels. Fig. 3 is a detail vertical section on the line :zz-x of Fig. 2Q

Fig. 4 is a detail View of the h-ubofan operating-wheel. Fig. 5 is a similar view of a seed-box.

Similar numerals of reference indicate corresponding parts in all the iigures of the drawings.

l designates the main or supporting frame of the planter provided at its front end with ,verticalguides 2, in which are fitted standards 3 bearing ground-wheels 4, said standards being connected at their upper ends by a cross piece 5, to the cen-ter ot' which is fulcrumed a lever 6 connected by means of a link or chain 7 with" the front beam of the main or supporting frame. The depression of -the rear end of this lever causes the elevay tion of the front end of thesupporting frame.

a shoulder 12, upon which saidrear bar rests'.

Fixed to this stem'above the plane of the main frame ofthe machine is the drivers seat 13 and by vswinging this seat to the right Aor left theI rider may direct the machine to bring it into proper alignment with the rows.

Eig. 2 is a transverse sectionv ing frame of the machine is an auxiliary or adjustable frame 14 having side bars 15 and a connecting cross-bar 16, and depending from this cross-bar upon opposite sides of its center are standards 17 bearing the dish-shaped covering or hilling wheels 18. Said adjustable or lauxiliary frame is secured inthedesired position with relation to the main frame by means of van arm 19, which extends backward from the cross-bar 16, and is provided with a series of perforations 20, one of which is adapted to be arranged in registration with a socket 21 spider-Wheels 24, which'are of the rimless con- Mounted slidablyv upon the main or supportstruction, and consist of a series of radial spokes 25 connected to a hub 26, .which in the Vconstruction illustrated is common tothe two wheels, whereby said wheels rotate simultaneously. Secured to the outer sides of these operating or spider-wheels are the cylindrical sleeves 27, which are open at their outer ends and receive the cylindrical seed-boxes 28.

The hub of the operating Wheels is mounted rotatably upon the boxing 30 fitted upon an angular shaft 3l, said shaft being extended laterally beyond the aboverdescribed seedboxes, and fitted in angular seats 32 near the front ends vof the side arms of the auxiliary or adjustable frame, and the seed-boxes which arelprovided with closed ends have angular openings 33 formed iu said ends to engage this angular shaft, whereby the seed-boxes are held stationary during the rotation of the v sleeves 27 and the operating-wheels.

Inclosing the sleeves 27are the cylindrical shells 34 having open inner ends and closed outer ends provided With angular central openings 35 which receive and fit the shaft 3l. The construction of both sets of seed-boxes,

contiguous operating wheels, and shells is identical, and therefore a specific description of one will suffice to give a clear understanding of the invention. at its-upper side with an opening 3.6whih is adapted when the sleeve 27 is 'in proper posi- The shell is provided l tion to register with a similar opening 37 in the latter, said opening 36 being permanently in registration with an opening 3S in the upper side of the seed-box, and therefore when said opening 37 in the sleeve registers with the openings 38 and 3G seed may be introduced into the seed-box.

The seed-box is provided in its under side with an elongated opening or slot 39 which registers permanently with an outlet opening 40 in the outer shell, and the sleeve which acts in the capacity of a rotary slide for controlling the outlet of grain from the seed-box is provided at diametrically opposite points with gage openings 41, which are successively brought into registration with the openings 3G and 39 to open communication between said openings, and thus allow the escape of grain. The reason for elongating the opening 39 is to enable the grain within the seedbox to pass out through said opening and into the opening 4l before said opening 4l reaches registration with the outlet opening 40 in order to prevent choking and insure the proper outlet of the grain.

Attached to each operating or spider-wheel are the seed-chutes 42, and in the construction :illustrated in the drawings each operating-wheel is provided with two diametrically opposite chutes, the upper enlarged ends of which are disposed respectively opposite and in the position to receive grain from the gage openings 4l when the latter are brought into registration with the outlet openings 40. Thus as the operating-wheel rotates by the contact of its spokes or arms with the ground, the seed-chutes are brought successively into registration with the outlet opening 40 just as the gage openings are arranged in registration with said openings 40 and 39, and therefore grain is successively fed into the chutes and conveyed by the latter to the ground.

Located in the outlet end of each seed chute is a plunger 44 having a stem 45, upon which is coiled a spring 4G bearing at its upper end against a stop 47. This plunger fits loosely in the outlet 48 of the chute, and its actuating spring is sufficiently light to allow the plunger to be repressed when the end of the chute is brought in contact with the ground, but when the chute is elevated the plunger reassumes its normal position and thus expels any earth which may have remained in said outlet opening which would prevent the choking of said chute. Each seedchute is provided with a marker 49 which indicates the hills as they are planted.

This being the construction of the improved planter, the operation thereof, briefly stated, is as follows:-To avoid running the machine forward or backward or turning the operating wheels by hand in order to place the first hill at the desired point in the row, I employ the auxiliary adjustable frame above described, which may be moved forward or rearward to secure the necessary adjustment. As

the operating or spider-wheels rotate by con` tact with the ground the seed-chutes are alternately brought into registration with the outlet openings of the shells at the same time that the gage-openings in the sleeves carried by said operating-wheel register with said outlet openings, and as the seed descends through the chute the discharge openings at the lower ends of the same are opened by the repression of the plnngers.

It will be understood that in practice, various changes in the form,proportion, and the minor details of construction may be resorted to without departing from the spirit of the invention or sacrificing any of the advantages thereof.

Having described my invention, what I claim isl. In a corn planter, the combination with a supporting framework, of an operating wheel, a seed-chute carried by the operating-wheel, a stationary cylindrical seed-box arranged concentric with the axis of the operating-wheel, and a sleeve carried by the operating-wheel,

3. In a corn-planter, the combination with a supporting-framework, of an operating-wheel, a plurality of seed-chutes carried by said wheel, a stationary cylindrical seed-box provided in its lower side with an outlet-opening, and a sleeve carried by the operating-wheel mounted rotatably upon the seed-box and provided opposite each seed-chute with a gage opening adapted to register with the outletopening in the lower side of the seed-box, substantially as specified.
