'lhe nature ot' onrinvention consists in forniing on the under side ot' theipertorated plates ot' rotary-action planting-machines certain curved grooves, to be hereinafter described.

The construction and ope ation ot' the machine are as follows, viz:

To the frame a, which is composed of two pieces meeting in front. and diverging thence to the rear end, the #handles bare attached, also the draft-bar c and elevis-d.

An annular pertbrated plate., e, tits loosely in a circular' rabbet, in the square plate or bed g,V which is bolted to the frame d, and has a circular opening corresponding in size and position with the opening in the plate t'. The hopper ltis placed upon and is attached to the plate g. Q

To the under side ofthe t'ramc u is secured a double inold-boaid plow, t', with cuttingedge in front and double-edged shovel-shaped share 1.',

Under the plate g, and cor-respoiuliug with an oblong opening, l, in the rabbetj', is placed a tube, m, extending thence to the ground between the wings ot' the plow i.

The circular'hopper-bottoni it, a little larger titan the openings in the piates e and g, is fastened to and sustained by a cross-piece, e, at-

tached to the rear end ofthe hopper 11,011 the inside.

To the under side of the cross-piece o, and bearing upon the annular plate c, is attached an elastic brush, p. Another brush, q, is at.- taehed to the inside ofthe hopper li. at t', also bearing upon the. plate e. i l

1n the front end of the hopper It., and having its bearing therein is a small shaft, s, to the inner end of which is attached an elastic scraper,t, the lower end ot which bears upon the perforated plate e. 0n the outside end ot'l the shaft s' is keyed an arm, il, which is furnished with a hole at the end, through which a pin, @passes into 'any one ot' a series ot' holes bored ian the front ofthe hopper it in an are o t' a circle of which the arm n is the radius, thus forming an adjustable apparatus by which tite pressure of the scraper t against the surface of the plate e is regulated according to circumstances. The object ot' the scraper tis to cause the grains of corn or other flat'seeds to lie upon their tlat sides in the holes in the perforated plate e as 'they pass in succession under it, and it' two grains should present them lselves eudwise or upright one will be scraped out and the other laid flat. lt' by accident; both grains should be scraped out, the hole has ample opportunity to tilt again in its passage under the brushes p and q to its outlet at l,- bnt this contingency7 will seldoni'oceur, as the scraper is capable ot` such delicate adjustments b y means of the apparatus above described that its action is tolerably certain, and, it' found necessary', one or more extrascrapers ot' similar construction can be added.

The roller wis tixcd to the. shatft which has its journals attached to the frame c at the rear end of the machine. 'lhe roller '1c serves' close the earth over it, and to act as a drivingwheel tothe internal machinery when the teatri is in motion. This' is eiected by placing on the shaft .r a beveluvhccl, y, which' worlisjinto another bevel-wheel, e, on the end of the longitudinal shalt u. 'This shaft is supported at its rear end by the adjust-able journal-box c', This journal-box is made in the fornrof a rightaugie, the vertical or depending portion containing theI bearing of the shaft a', and the horizontal portion placed transversely on the under side of one ofthe trame-pieces a, where it is held inA position by the hookedvbolt o',

which passes through the frame-piece ai, and,4 by means of the nut and screw-thread on top of the frame, holds the journal-box c firmly in its place, unless it is required to be shifted to accommodate'a larger or smaller wheel, when diterent relative speed is required in the machine, in which ease, the nut being unscrewed, thejournal-box c is readily adj usted andagain secured by screwing down the nut.

The shaft a. is journaled at its forward end in the cross-piece i', attached to the under side of the frame a, and is furnished with a pinion, d', working in the toothed wheel el, fixed on the vertical shattf, which has its journals in the cross-piece i', and another cross-piece,j, attached to the plate g.

Q11 a square ou the top ot' the shaft f is placed a movable cross-piece, g', notched at the ends to iit the projections h on the inside of the revolving` perforated plate c. The plate e has on its under side a seriesoi' curved grooves, as represented in Figs. S and il, which are intended to conduct all dirt, chaii, which may insinuate itselt` between the plates e and g toward the periphery ot' the plate e, whence it'ialls through the opening l into the tube nl. This is an important improvement, and obviates the diiiiculties occasioned by an accumulation of dirt, Sie., between the plates, which, by separating them, may occasion-l derangement and irregularity in the operation ot' the machine in consequence ot' the small end ol' a grain ot' corn getting jammed between the plates.

`The plate e, in the proportion as represented in Fig. 4, is calculated to plant corn in drills by single grains about one foot apart; but by another arran gementof holes, as in Fig. 10, we, are enabled to plant three or four grains about one inch apart, then leave a vacancy of three J or four feet, thus leaving the corn in' hills, which will allow it to be worked both ways, if attention is paid to starting the tirst hills at the end.

of the field in a true line.

When the team attached to the machine is Setin motion, the hopper h being liiled with cern, the plow 'i opens the furrow, and is ibllowed by the roller w, bearing upon the ground, which, by means ot' the shaft a; and wheels 1/ and z, communicate motion to the shaft u and pinion d', which move the wheel e and shaft j", while the cross-bar g', fitted on a square on the upper end of *he shat'tf', causes the annular perforated plate c to revolve in the circular rabbet j', each hole in the plate e beingot suitable size to contain only one grain of corn laid. iiatwise. l't two should enter in any other position, one will he removed by the adjustable scraper tand the other placed in the proper-position. The grain thusplaced in the hole is carried round to the opening t in the plate y, through which it falls into the tube m, which conducts it into the furrow, where it is covered by any ot' the usual contrivauees, and the earth is pressed upon it by the roller io.

What we claim as our invention, and desire to secure by Letters Patent, is-` 'lhe combination ot' annular revolving perforated plate o, with curved grooves on the under side thereof, constructed substantially in the manner and for the purposes described.

In testimony whereot' we have hereunto signed our names before two subscribing.;` wit nesses.
