SEED-DRILL.
SPECIFICATION forming part of Letters Patent No. 734,049, dated July 21, 1903.
Application filed November 11, 1302. Serial No. 130,849. (No model.)
To all whom it may concern:
Be it known that I, PETER W. EKSTRAND, a
citizen of the United States, residing at C0- and preventing them from becoming clogged while passing through the :feeding mechan- 1sm.
To this end my invention consists in the features of construction, combination, and arrangement of parts hereinafter particularly described and claimed.
In the accompanying drawings, forming part of this specification, Figure l is a side elevation of the drill-shoe, showing my invention arranged in connect-ion therewith. Fig. 2 is a top view of the same. Fig. 3 is a front end view. Fig. 4 is a rear end view. Fig. 5 is a top View of the feeding mechanism. Fig. 6 is a section on line a; :r of Fig. 5. Fig. 7 is a section on line y y of Fig. 5. Fig. 8 is a side view of a segmental block forming a part of my device, and Fig. 9 is a view of the under side of said block.
In the drawings, A represents the drill-shoe or furrow-opener, carried by the framework 2 of the drill. Supported from the rear end of the shoe are the ordinary furrow-covering blades 3. Supported above the rear end of the shoe A is the seed-receptacle B, provided with a downwardly-extending outlet-tube 4. Arranged in the bottom of the receptacle B is the disk 5, secured upon the vertical shaft 6. Upon the lower end of the shaft below the receptacle B is secured a beveled gear 7, intermeshing with a similar gear 8, mounted upon the transverse shaft 9. Uponthe outer end of the shaft 9 is mounted a sprocket-wheel 10, connected by a chain 11 with the driving mechanism of the drill. (Not shown.) The disk 5 is provided inside its outer edge with a series of openings 12, adapted to be brought into registering position with the upper end of the outlet-tn be 4 in the rotation of the shaft 6. Secured within the receptacle 13 directly above the disk 5 is the segmental block 13. The under side of the outer wall of the block 13 is cut away to form an opening 14, a passage 15 being formed in the under side of the block from the opening 14 to the outer edge of one side of the block. Secured to the outer edge of the block above the end of the passage 15 is a brush 16, the bristles of which extend downwardly in front of the outer end of the passage 15. A finger 17 extends downwardly in front of and slightly to one side of the center of the brush 16, the lower end of said finger standing in front of the bristles of the brush and the upper end of the finger being secured to'the block, as shown in Fig. 5. Secured to the block 13 inside the opening 1% is a wheel 18, provided with teeth 19. The wheel 18 is so positioned that one of its teeth will project through one of the disk-openings immediately above the outlet-tube 4. As the disk 5 is turned the wheel 18 will be turned, causing the teeth of said wheel to force the seed out of the disk-openings into the outlettube 4. The framework and driving mechanism of the drill may be of any desired construction and are therefore not shown in the present drawings nor described.
In operation the shaft (-5 will be rotated in the direction indicated by the arrow in Fig. 5. The openings 12 in the dropper-disk are preferably of such size that when the seeds are placed in the receptacle each of said openings will receive and hold one of the seeds. As the disk is rotated the openings 12 will be brought into registering position with the outlet-tn be 4:, the seeds in said openings dropping through said tube to the ground. In order to prevent more than one seed being carried by each of the disk-openings under the block, I provide the brush 16, which willsweep the disk immediately in front of the passage 15 and hold back all of theseeds except the one in each disk opening. In case two seeds become jammed in one of the diskopenings the finger 17, which stands slightly to one side of the center of the brush, will engage with the outer seed and-hold it back. As the disk-openings register with the upper end of the outlet-tube 4 the teeth of the wheel 18 will force the seeds into the outlet-tube.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In dropping mechanism for seed-drills, the combination with a seed-receptacle provided with an outlet-opening, and a rotary disk arranged within said receptacle and provided with seed-openings, of a block secured in the outlet side of said receptacle above said disk, the under side of said block above the outlet-opening being cut away and provided with a passage leading from said cutaway portion to the outer edge of the block, and a brush secured to the outer wall of said block in front of said passage, as and for the purpose set forth.
2. In dropping mechanism for seed-drills, the combination with a seed-receptacle provided with an outlet-opening, and a rotary disk arranged within said receptacle and provided with seed-openings, of a block secured in the outlet side of said receptacle above said disk, the under side of said block above the outlet-opening being cut away and provided with a passage leading from said cutaway portion to the outer edge of the block, means for sweeping the disk at the outer end of said passage, and means supported in the inner end of the passage for removing the contents from the seed-opening registering with the outlet-opening.
3. In dropping mechanism for seed-drills, the combination with a seed-receptacle provided with an outlet-opening, and a rotary disk arranged within said receptacle and provided with seed-openings, a block secured in the outlet side of said receptacle above said disk, the under side of said block being formed with a passage-way leading from the outer edge of the block to said outlet-opening, a brush supported in front of the outer end of said passage-way, and a toothed wheel supported in the inner end of said passageway for forcing the contents from the seedopening registering with the outlet-opening.
4. In dropping mechanism for seed-drills, the combination with a seed-receptacle provided with an outlet-opening, and a rotary disk arranged within said receptacle and provided with seed-openings, of a block secured in the outlet side of said receptacle above the disk, a brush secured to the face of the block in position to sweep the seed-openings, and a finger projecting, downwardly in front of said brush and slightly to one side of the same, for the purpose described.
5. In dropping mechanism for seed-drills, the combination with a seed-receptacle provided with an outlet-opening, and a rotary disk arranged within said receptacle and provided with seed-openings, of a block secured in the outlet side of said receptacle above said disk, the under side of said block above the outlet-opening being cut away and provided with a passage leading from said cutaway portion to the outer edge of the block, a toothed wheel carried by the block and cooperating with'the seed-openings in the disk, a brush secured to the outer wall of said block above said seed-openings, and a finger projecting downwardly in front of said brush slightly to one side of the center thereof.
In testimony whereof I affix my signature in presence of two witnesses.
