Letters Patent No. 109,936, dated December 6, 1870.

IMPROVEMENT IN CORN-PLANTERS.

The Schedule referred to in these Letters Patent and making part of the same.

I do hereby declare that the following is a. full, clear,

and exact description thereof, reference being had to the accompanying drawing.

Figure 1 s a perspective view of myimproved cornplanter.

Figure 2 is a bottom view of lig. 1, partly insection.

Figure 3 shows the 'discharge-aperture, the cap bcing removed.

Figure 4 is an inside View of the cap.

Figures 5 and 6 are transverse vertical sections, taken on the line a: n; of' iig. 2, the rst showing the discharge-aperture open, and the latter closed.

Similar letters ofreference refer to indentical parts in each of Ithe figures.

To' enable others skilled in the art to which my invention relates to make and' use the sam-e, I will proceed to describe the construction and operation. Y

In .the annexed drawing forming a part ot' this specificationy A represents a cylinder, within which the seed is to be deposited'which it is desiredto Ahave sown.

It has a tube running through its center for thereception of the hoe-handle.

At the lower under side of the seed-cylinder there' is inserted a bung, B, having an opening in it, which has arranged upon one side-a brush, b, as shown iu tig 3. A

Over these parts the cap C is placed, which has an opening in'its face, as shown in iig. 2, and by dotted lines in fig. 4.

Within this cap rotates the slide D, having an aperture which can be increased or diminished, so as to hold more or less seed, by means of the guide d, which has a slot in it and is secured to the slide, as shown in fig. 4. V

The slidev has a hook or eyelet, which Aprojects i through a slot in the cap C, to the shank of which one end of spring E issecured, the other end `being fastened on the reverse side of the cap.

The action ot' this spring upon the seed-slide D is suoli as to hold it closed, as indicated by dotted lines in tig. 2.

The dotted lines upon the face of the cap C indicate the position of' tbeaperturein the slide D where the same is closed.

The brush b is to act as a scraper to the aperture in the slide D, as also to provide a pliable surface vto prevent the corn from getting between parts B and D, thus clogging and preventing free action.

The operation may be stated as follows:

The parts being in position, as shown in figs. 1 and 6, seed will fall and ll the apertures in the part 'B and the seed-slide D, the slide is then drawn into po,-` sition, as shown in iigs. 2 and 5, the aperture being thus brought immediately over the opening in the face of the cap G, and the seed falls to the ground.

The draft upon the slide is then slackened, when the action of the spring E brings the parts to theirnormal position.

Its simplicity, durability, and certainty of performing the purposefor which it is designed must oommend it to those interested in the branch of industry to which it relates. y,

Having thus described my invention, y

What I claim, and desire to secure by Letters Pateiit of the United States, is-

The arrangement of the cylinder A, bung B, brush b, cap C, -slide D, guided, and spring E, substantially as shown and specified, and for the purpose 'set forth.

In testimony whereof', I have signed my name to this specification in the presence of two attesting' witnesses, this 1st day of August 1870. i

\ HENRY G. PORTER.
