IMPROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 134,032, dated December 17, 1872.

f To all whom it may concern:

ence being had to the" annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of a plan view of my invention. Fig. 2 is a longitudinal vertical section of the same. Figs. 3 and 4 are details.

This invention has relation to that class of corn-planters in which the seed-dropping devices ride upon the shoes which are pivoted to the front of the main frame; and it consists in the construction and novel arrangement of the concave couplings connecting the front and rear portions of the main frame, whereby the seed-boxes are brought near the ground, the dropping-tubes and their valves shortened with a view to an increase of angular space between the valve and the tubewall, and ease of movement when operated by the seedslide.

In the accompanying drawing, the letter A designates the main frame of the corn-planter; B, the wheels; C, the axle; andk D, a pivoted bar at the rear end of the frame, holding scrapers d, and operated by a foot-lever,

d. The longitudinal bars A of the main frame are made in two parts and united by concave coupling-plates a, forming notches to receive the transverse bar of the seedingframe when it descends below the level of the frame A. To the forward part of the frame A is pivoted the seeding-frame, consisting of the transverse bar B and arms b. The latter are pivoted to .the ends of the front bar of the main frame. The bar B vibrates in and over -the concave couplings, and supports the seed-boxes E, the seed-dropping devices, seat e, seed-shoes e1, and adjustable guiding-roller e2. F indicates curved plates secured to the seed-shoes and pivoted to the bar A2. Two of these plates are attached to each shoe, and, passing forward parallel with each other, are secured by the pivot-pin on each side of the arm b of the seeding-frame. Between the curved plates of each shoe is pivoted an opening-wheel, Gr. At each end of the bar B', on its upper surface, is secured a plate, c, centrally recessed or channeled to receive the end of the seed-slide d. The plate c is also slotted at its center for the passage of the seed, and at the side of the channel for the passage of the stud a of the valve z ofthe dropping-tube, said stud being connect-ed with said valve by a shank extending horizontallyunder the plates c. This plate is also slotted at its side to permit the passage and play of the arm j' of the slide-ba-r, said arm f bearing on the adjustable forked stop-plate m, which regulates the size of the seed-openings through the slidebar, and is connected to the arm f by means of a clamp-screw. Opposite the arm f are placed, on the slide-bar, two small lugs or projections, o, which extend into the lateral chamber of the recess of the plate c and elnbrace the stud n of the tube-valve, serving to communicate to said valve the reciproeating motion of the slide-bar, causing the same to vibrate regularly in its tube e1. Underneath the bar B are secured stirrups h', in which are stepped the levers or handles which pass through the said bar B and the seed-slide, and serve to operate the latter. Each plate c is provided at its corners with upwardly-projecting pins or studs o', which pass through perforations in the flanches d of the seed-boxes, thus securing said boxes in position, and at the same time permitting them to be easily removed, when necessary, for repairing the seed-slide or other purpose. Each box is provided with a bent plate, under which is secured the seed-brush. Thus the brush is removed from the slide with vthe box, enabling the operator to adjust the stopplate m with facility. The bar B may be raised by means of a lever, H, pivoted to a standard-plate, J1., on the axle, and operated in rear. Underneath this bar B,'and at the inside of each shoe, is secured an adjustable gage-wheel.

Having thus described my invention, what I claim, and desire to secure by Letters Pat- In testimony that I claim the above I have eut., s hereunto subscribed my name in the presence In a seeding-machine having the hinged of two Witnesses.
