.IMPROVEMENT IN SEED-PLANTERS.

Specification forming part of Letters Patent No. 7.187, dated March 19, 1850.

To all lwhom 'it may concern:

Be it known that I, JOHN P. GRosHoN, of Yonkers, in the county ot' Westchester and State oi' New York, have invented a new and useful Improvementin a Machine f'or Planting l Corn or other Grain, Seed, dto.; and I do hereby declare that thei'ollowingis a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure lis a general view. Fig. 2 is a plan view as seen from above. Fig. 3 is a longitudinal section. Fig. 4. is a detached view ot' the levers. t

Similarletters refer to corresponding partsin all the figures.

The nature of my invention consists in the construction of a machine provided with a hopper into which the corn or other grain to be planted is deposited. rlhe bottom ofthe hopper is provided with a slide having holes perforated therein, through which the grain will fall as these holes are moved over corresponding holes in the bottom ot' the hopper. This slide is worked by studs acting upon jointed levers, said studs being attached to the wheel on which the machine is supported, and which is made to revolve by the drawing power. The maehineis provided with a share for making the t'urrows, and with rakes for closing it after the seed has been deposited; also, with a slide whereby the person operating can shut ott' the grain while the machine is still propelled and the irst-mentioned slide consequently operating.

To enable others skilled in the art to lnake and use my invention, I will here describe its construction and operation.

A A represent the frame of the machine.`

`holes c c for letting out the corn. D is the shaft, mounted in bearings d d on the frameof the machine. E is a lever fast oli the shalt D and jointed by a pin to the connecting-rod F, which connects it with the slide O for the purpose of opening the holes cc. G is another lever fast on the shaft D, and has jointed toit a smaller lever, g. E is a shaft mounted in hearings h h on the frame and carrying the lever 1, which is jointed by a pin to the connectingfrod J, which connects it with the slide O for the purpose oi' closing the holes c c. K is another lever, made fast on the shaft H, and

| has jointed to it a small lever, 7c. L is the wheel, carrying any convenient number ot' pins or studs, l l, on one 'face for Astriking the 1evers G g, and thereby opening the holes c c. l* L* are studs on the opposite face ofthe wheel L for the purpose ot' striking the levers K la and closingthe holes c c. M isaslide provided with holes c c for the purpose ot' opening or closing the supply of corn or other grain at the pleasure ot the person operating the machine. Vis the bottom ot' the hopper, also provided with holes c c. N is a shaft working in hearings n a in the frame. Ois a lever fast on the shaft N and jointedat its lower end by a pin to the slide M, and having at its upper end an arm, o. P is a shalt working in bearings and carrying the lever Q, which has a long rod, B., firmly attached to it. S is a conneeting-linkjointed by a pin at one end to the arm o of thelever O, andatthe other enti to the rod R. -T is a share for opening the furrow, and U U are rakes for closing the earth over the seed. rihese rakes are attached to screwed rods passing through sockets in the frame and secured by nuts on each side. The height may be regulated by merely screwingor unscrewing the nuts, as may be desired. NV are handles for `guiding the machine.

The operation is as follows: The drawing power being attached, the lever Q is pushed forward by the person operating. This will cause the end of the rod l to descend and draw back the upper end of the lever O and open the slide M, so that its holes are over those inthe bottom V ot' the hopper. As the machineis drawn along the furrow will be made by the share T, the wheel L will revolve, and the studs L l and l* l* will strike alternately the levers gandk.- When the lever gis struck by one of the studs Z the lever E Will beraised and the slide O drawn back until the holes c c are over those in the slide M, when a kernel of corn or grain Willt'all out. Bytlhe continued revolution of' the wheel one of the. studs Zt will strike the lever k, and the lever l will then he raised and the slide O pushed forward till the holes c c are removed from those in the slide M, when they will he closed, but will he again opened by the nextstud L in the wheel L. Each stud, by striking one ot' the levers, will leave the other lever in the proper position to be acted upon by the next stud. The fnirows will be closed and the seed covered by the rakes 2 wie@ U U as themachine is drawn along. Should ward the upper end ot' the lever O, thereby any obstacle. present itselt1 in the way of the machine and causea recoil, or should the wheel L be in any way caused to run backward, the levers g and 7c will tiy up on being struck by the studs l or Zi to the position shown in dotted lines at Fig. 4, thejoints between the levers g and 7c and those G and K being formed with shoulders of the shape shown in the drawings. These shoulders will meet and form a rigid lever when the pressure is applied on the upper side.

When the person operating the machine desires to close the holes c c the handle or lever Q, must be pulled toward him, which operation will raise the end of the rod Rand throw forvent the slides from beimg` actuated when the motion of the Wheel is reversed.
