IMPROVEMENT IN SEEDING-MACHINES.

1861; reissue No. 7,191.. dated d, which, in the absence of the inclined planes, would be contained in the space below them,` the most of which would not flow into the inelosures formed by the tr a., which, by sliding ansvcrse vertical partitions, land also serve to conduct the seed contained in the seed box or hopper into the inelosures ing-machine of that c seed broadcast or in' close drills; and consists for discharging or disin an improved means tributing the seed, as hereinafter shown and described.`

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

' A represents a seed box or hopper, which is secured to an axle, B,. the wheels C C of which are placed loosely on it. D is a draftpole attached centrally to the axle B. The mainv seed box or hopper A extends the whole length of the axle B, or nearly so, and within the seed box or hopper there are placed transversely vertical partitions ax, which extend nearly down to the bottom ofthe seed box or hopper, and form inelosures for Athe reception of seed-distributing wheels, an ed to admit the seed from the hopper A to the seed-distributin the inelosures tical partition s. which are place by the transverse vertic are fitted'on a shaft, F, th nally through the hopper shaft F there are placed which, G, is larger than t wheels G H gear, respec wheels I J on the hhbs The wheels Gr H are p ends ofthe shaft F, and freely thereon, each whee g wheels in of the wheels C C d are constructseed box or o med by the transverse ver- E are seed-distributing wheels d within the inelosures formed al partitions ax, and

at passes longitudi- A.. At the ends of wheels G H, one of he other, H. These tively, into toothed laced loosely on the are allowed to slide l having a ratchet,

formed by the` transverse vertical partitions, from which it is distributed by the action of seed-distributing wheels. The shaft F is tted with rods or stirrers d, passing through it outside of partitions 01X, which as the shaft revolves, serve to agitate the seed to prevent 'ts passage from the hopit from clogging oni per A to the seed-distributing wheels in the inelosures formed by the transverse vertical partitions a". The wheels E are provided at their peripheries with tubes G','which have a tangential position, as shown in Fig. 2, and each tube is provided with a sliding head, e,` by which its capacity may be cum stances may require.

The peripheries of the wheels E, between the tubes G', are bev inclined planes, as shown at f in Fig. 1, and to the inner side of each partition tx there is attached an inclined trough, g, which extends down to openings h in the back of the seed box or hopper A. (See Fig. 2.) The openings h communicate with the upper parts of s H, which have a ill be seen the wheels eled so as to form doublevE will be rotated, and the tubes G' will carry up the seed and discharge the same at the top of the WheelsV upon the beveled peripheries j', the latter dedecting the seed into the troughs g, which conduct it into the spouts H', the partitions I' dividing the seed, so that it will fall in equal quantities through the passages t' i. The seed falls on the bars J', which scatter it, so that it falls on the ground in a broadcast manner.

The division ofthe seed of each tube G' by the beveled peripheries f of the Wheels E and the Vshaped partitions I',in connection with the scattering-bars J', insure a perfect distribution of the seed.

The quantity ot' seed to be sown on a given area may be regulated as desired by varying the speed ot' shaft F. When the Wheels Gr I are used for rotating shaft F the latter will rotate, of course, slower than when the wheels H J are used. The distribution ofthe seed may also be regulated by adjusting the heads c of the tubes G' so as to vary the capacity of the latter.

When it is desired to soW seed in close drills instead of broadcast, as described, the spouts H' are detached, and spouts K secured in their place. The spouts K are externally ot' the'same form as the spouts H', but the former are provided with a vertical central passage, b", as shown in Fig. 4, and the scattering-bar AJ'is dispensed with. rIhe sides cX of the partition, corresponding to partitions l' in the spout H', are movable or adjustable longitudinally, so as to vary the area of the orifice of the central passage bx, and the area ot' the lower ends of the side passages d", which correspond to 'i in the spouts H'. The spouts K, therefore, it will be seen, discharge the seed at three dii'erentpoints, to wit, at the. lower ends of the passages dx d* b".

I do not claim the employment or use of seed-distributing wheels provided with seedoups having adjustable or movable bottoms, for such device chines; but

I do clailn as new, and desire to secure by LettersPatent- 1. In combination With the Wheels E and troughs g, arranged as shown, the inclined surface or planes c placed at the bottom of the hopper A, and in the described relation with the partitions ax thereof', to operate as and for the purpose set forth.

2. The spouts H' provided with the partitions I' and scattering-bars J', in combination with the seed-distributing Wheels E, partitions et", and troughs g, all arranged as and for the purposeset forth.

3. The transverse vertical partitions ctx in main seed-box A, forming inclosures for the reception of seed-distributing wheels, and constructed to admit the seed from the main seed-box to the seed-distributing wheels in the inclosures formed by the partitions, substantially as described and shown.

4. The stirrers d, in combination with the inclined planes c and partitions ax, for the purpose of agitating the seed to prevent it from clogging on its passage from the main seed-box A to the seed-distributingwheels in the inclosures formed by the partitions ax, substantially as set forth.

'5. The double inclines c, transverse vertical partitions ctx, and seeddistributing Wheels, tted to revolve in the inclosures formed by the partitions, these parts constructed and arranged in the main see'd`box ot' a seedingmachine, and combined for joint action, for the purpose of discharging the seed from the main seed-box as the machineis drawn along, substantially as set forth.
