AIMPROVEMENT'` l-N HAND CORN-PLANTERS.

Specification forming part of Letters Patent No. 36,8 l5, dated October 28, 1862A.

zontal section ot the same, taken in the line Fig-fl i Similar letters! of reference indicate corresponding parts in the two figures.

This invention relates to an improved cornplanter of that class which are designed for manual operation; and vil: cousis'tsin a novel arrangement of a plunger provided with a seed-cell, and used in connection with a cut-oft' or partition, spring-plates, and a stop, arranged in such a' manner that the device may be operatedv and the seed -'111,ea`su'red, dropped,and planted with the greatest facility.

To enable those Skilledin 4the art to fully understand and construct ourinvention, wewll proceed to describe it.

A represents a box, the two `'opposite Vsides a a of which may be of sheet metal, secured to the'other side pieces b' c, which may be of wood, by screws -or nails. The side piece bdoes not extend downto the lower ends of the sidepiecesI a a, audit has a curved metal plate, B, secured to its lower-end, the elasticity of which has a tendency-to keep its lower end in contact with a metal plate, d, which is attached to the inner surface of a wooden strip,

e, secured between the lower partsofthe sides a c, opposite to )late B, asshown in Fig. l. The plate d projects some distance` below the strip c, andto the back side or outer surface ofthe latter a gage, C, is attached, which regulates the depth of the penetration of plate d into the earth. This gage is simply a wooden block secured by screws to the strip e at a greater or less height, as may be desired. The strip e is not in lille with the side c o t' the box; it inclines farther outward, as shown in Fig. 1. D is a plunger, which is fitted in the box A, and is allowed to slide freely up 'and down y therein between the side c and a guide, lf,.iu the upper part of box A. This-plungerD has a recessg,jmade in its surface, in which a slide, h, is fitted and adjusted at any point by a screw,, which passes through a slot,j,. in

the plunger. This recess g is ot' oblong form', l

extending horizontally nearly across'the plunger D, and has its lower edge inclined.

E is an inclined partition'in the box A, having a brush, k, at one'end, Iwhich bears against the inner Surfaceot' the plunger. D. The space in the box A above the partition E isthe seedhopper. In the box A, below the partition E, thereis a curved elastic plate, F, thelower end ot' which bears against the inner surface ot the plunger D. The lower end ot' the plunger D may be shod with metal, as shown at Z. In the inner surfacewf the plungerD there is made a recess,m, which has an inclined bottom, n, as shown in Fig. 1.

" The operation is as follows: When the plunger D is drawn. upward, the recess g, the

capacity of which is regulated by adjusting slide h, will become filled with seed,- andjas the plunger is forced down the recess g'will pass below the brush It', and theseed will then fall from the recess into the space between the partition E and the elastic plate F, the latter serving as a bottom for said space and retaining theseed. When the plunger is again drawn up for the recess. g to be vfilled, the seed previously discharged and retained by the plate F will escape through the recess m into the space below F, said recess arriving at the lower end of F when the recess g passes into the seedhopper. When the plunger is again depressed the recess m passes below F before the recess g passes below the brush k,and hencethe plate F retains the seed until the recess m again .rises toliberate it. At each descent ot' theplunger after being once moved down and up,- the seed in the lower space on plate B is forced into the earth, the plunger forcing outward said plate, which, by its elasticity, returns to its original position eachtime the plunger` rises.

The case Ais adjusted over the spots where the seed is to lie-deposited, and the plunger D operated by hand. The whole arrangement is extremely simple and efficient.

In order to limit the upward movement of the plunger D, a stop, Gr, is 'attached to the o'u'ter surface of the plunger, which comes in contact with the lower ,edge ofthe side c; and

in order to avoid concussions a spring, o, is at-u' tachd-'t-o the upper end ot' G, as shownin Fig. l, which spring breaks the force of the blow and prevents any disarran gement of the working parts l We do not claim separately any of the parts herein shown and described; but

, What we do claim as new, and desire to seonre by Letters Patent, is-

1. The plunger D, provided with the recesses 4to operate as 'and for the purpose herein set forth.

2. The stop Gr, attached to' the plunger` D, and provided with the spring'o, when arranged relatively with the side -o of the box A, and

' used/in combination with the elastic platesvF B,'""inclined partitions l brush 7c, and xed plate d, as and for the purpose set forth.
