SPECIFICATION forming part of Letters Patent N 0. 633,634, dated September 26, 1899.

Application filed March 9, 1899.

T0 aZZ whom, it may concern;

Be it known that I, LINDLEY, A. WRIGHT, of Ohampaign, in the county of Ohampaign and State of Illinois, have invented certain new and useful Improvements in Seeders, of which the following is a specification.

This invention relates to broadcast seeders. It is designed to provide superior means for interminglin g one seed with another,as cloverseed with oats, preparatory to sowing. It is exemplified in the structure hereinafter described, and it is defined in the appended claims.

The principal feature of the invention is based on the discovery that if the discharge end of a pipe or other conveyer for cloverseed is placed in the current of a moving body of oats or the like the action of the oats will cause the clover-seed to flow freely and commiugle uniformly with the oats. The efficiency of the operation is improved if the discharge-openings of the clover-seed conveyers are presented somewhat in the direction the oats are moving and a downward feed is best; but advantageous results are obtained under various conditions so long as the dischargeopenings of the clover-seed conveyors are in the moving currents of oats and the oats do not move directly against the openings. The currents are formed in the oats some distance above the discharge-openings of the oats-hopper and they continue until the distributer is reached, so that a flow of some little length is provided, in any part of which the cloverseed conveyers may discharge.

In the drawings forming part of this specification, Figure 1 is a central vertical section through an oats-hopper and a clover-seed receptacle supported in the upper end of the hopper. Fig. 2 is an elevation of a hopper, partly broken away, with which is shown clover-seed receptacles in difierentpositions communicating with different parts of the current of oats.

The oats-hopper is shown at 1, the bottom thereof at 2,and the outlet-openings at The clover-seed receptacle is shown at 4, the discharge-pipes of the receptacle are shown at 6, and closure-valves for the discharge-pipes are shown in the bottom of the receptacle at 8.

Serial No. 708,845. (No model.)

In Fig. 1 the receptacle is shown supported in the upper end of the hopper by means of cross-bars 5, while in Fig. 2 the receptacle is shown in solid lines connected to the inner surface of the oats-hopper and in broken lines connected to the outer surface of the hopper in two different positions. In one case the discharge-openings of the clover-seed receptacle communicate with the current of oat-s below the discharge of the oats-hopper, and in the other cases the discharge of the cloverseed is made into the current as it forms above the discharge-openings.

The form of the clover-seed receptacle is immaterial so far as the invention is conoats-ho pper is largel ya matter of choice. The conveyer-pipes 6 must be long enough to extend into the stream of oats and small enough to not impede the stream materially. They are preferably tapered from the receptacle downward, and their number depends on the number of outlet-openings in the oats-hopper. In the upper ends of the conveyers 6, below valves 8, are placed removable cone-shaped cups 7, having openings in their inverted apexes to permit the passage of the cloverseed. These cups are made in sets with openings of various sizes, the largest of which is'somewhat smaller than the discharge-openings in the conveyor-pipes, and their principal object is to regulate the flow of cloverseedfrom the receptacle. They have an other function, however, which is to retain alimited amount of seed to be discharged after the valves 8 are closed, and the purpose of this provision is to permit the clover-seed to be shut off before the oats-outlets are closed without depriving the oats that are planted in the interval of their proper admixture of clover-seed. Both seeds are shut off preparatory to turning around at the ends of the field; but the time for manipulating the valves comes just at the time that the team,

particularly a young or not thoroughlytrained team, needs special attention, and so it is more convenient to operate one set of valves at a time.

The oats-hopper is to be provided with a distributor for the commingled oats and cerned, and its location with reference to the clover-seed, and the discharge may be by gravity or by mechanical means. As the invention relates solely to the commingling of the clover-seed with the oats, the distributing or sowing mechanism is not shown.

Vhile the device is intended to mix cloverseed with oats, it is obvious that its use is not restricted to the particular seeds mentioned.

Vhat I claim is 1. The combination with a principal seedhopper having a discharge-opening, of a secondary seed-receptacle having discharge-openings located in the discharge-current of the principal seed. k

2. The combination with a principal seedhopper having a discharge-opening, of a secondary seed-receptacle having a dischargepipe extended into the discharge-current of the principal seed.

3. The combination with a principal seedhopper having an outlet-opening, of a secondary seed-receptacle, and a pipe extended from the receptacle into the discharge-current of the hopper, such pipe having a discharge-opening presented in the direction of travel of the current.

4. The combination with a principal seedhopper having an outlet-opening through which a downward current is formed by the discharging seed,of a secondary seed-receptacle having a discharge-pipe extending downward into the current of the principal seed and communicating downward therewith.

5. In a seed-feeder, the combination of a receptacle having discharge-openings and valves therefor, pipes extending from the discharge-openings and cups with contracted openings located in the pipes immediately below the valves, whereby alimited amount of seed is retained in the cups for distribution after the valves are closed.

In testimony whereof I sign my name in the lVitnesses:
