DISK HARROW AND SEEDER.

SPECIFICATION formingpart of Letters Patent No. 470,363, dated March 8,1892. Application filed August 3l, 1891. Serial No. 404,298. (No model.)

To @ZZ whom, it may concern.-

Be it known that I, GEORGE W. PACKEE, a citizen of the United States, residing at Rock Falls, in the county of Whiteside and State of Illinois, have invented certain new and useful Improvements in Disk-Harrow Seeders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyin g drawings, and to letters or figures of reference marked thereon, which form a part of this specification. 4

My invention has reference to improvements in disk-barrow seeders; and it consists, irst, in mechanism for drivinga rotating seedshaft from the inner disk of each gang by means of friction-wheels adapted to have their tread on the convex side of said disks and lto be actuated thereby; second, in means for adjusting said friction -wheels so as to equalize their speed in the different positions which the disk gangs may assume; third, in the provision of a spring to regulate the degree of traction upon the periphery of said friction-wheels; fourth, in certain improvements in the Scrapers for said disks. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a side elevation, partly in section, of a machine embodying my invention. Fig. 2 is a rear elevation of part of such machine. Fig. 3 shows details of the construction and location of the Scrapers and scraper-bar. Fig. 4 is the same with reference to the aforesaid mechanism for driving the seed-shaft. Fig. 5 is a sectional view through the axle F and friction-wheels E E.

Similar letters and figures refer to similar parts throughout the several views.

A is the usual seed-hopper, suitably supported upon a frame slightly in advance of the transverse draftplank B, to which the disk gangs C are attached pivotally in the usual way. Y

D D are the inner disks of each of the two gangs, which are of the usual convex-concavo conformation. l

F. E are friction-wheels placed upon their common axle F and provided with oblique faces conformable to the convex surface of the disks D, respectively. The disks D are rotated, of course, from and by their contact with the earth, and this rotation is imparted to the axle F of the wheels E thro ugh the traction of the latter upon the disks D.

The axle F is journaled transverselyin the outer end of a frame 2, which is hinged vertically at its inner end to any suitable part of the machine. On the axle F is centrally keyed a sprocket wheel G, from which a sprocket-chain communicates rotation to a sprocket-wheel Il, seated on the short shaft Il in front of the axle F and slightly below and in the rear of the hopper A. On the axle H is rigidly seateda gear-wheel J, which eugages a similar gear-wheel K, seated on the shaft K', which constitutes the axle or shaft of the seed-discharge device. A vertical rod l is pivotally attached at its lower end. to the frame 2, near the outer end of the latter, and is adjustably suspended by being passed vertically through a plate 3, attached to the draft-plank B, and .partially supported on said plate by means of the helical spring 4, coiled around said rod between plate 3 and upper collar 8, the latter being adjustable on rod 1 by the set-screw 9. The spring shown on' rod 1 below the plate 3 is separate and distinct from the spring 4, and said spring below said plate is simply a cushion to relieve the upward jar of the friction-wheels E.

The advantage of driving the seeding mechanism from the inner side of the disk gangs is that there is thereby avoided the refuse of various kinds which collects at the vouter end of the disk gangs. In use in connection with throw-in harrows the axle F would be longer and the bevel on the wheels E on the inner side of the latter. In driving from near the periphery of the upper portion of the disk there is an advantage over driving from the axle or from a sprocket-wheel seated thereon in that the disk gangs in use are often sunk in the earth to their axle, causing more or less interference with and sometimes a breakage of the driving-chain.

In order to equalize the velocity of the friction-wheels E through the variant positions of the disk gangs in use,I provide at each end IOO 1 or out in the end of the hub of the wheel E the space between said wheels may be increased or lessened,in which event the tread of the wheel E will be moved radially to or from the axis of the disk D.

L is a scraper-bar suitably supported in ways from the disk-gang axle and adapted to be moved laterally by the lever M, fulcrumed on the beam B and having its actuating end engaging a vertical clutch N, formed on the upper end of the arm O, the upper end of which projects upward through a slot in the beam B, and by throwing the lever M completely over laterally the barL is moved endwise to or from the disks. Slots are formed in the shoe P, in which the lever M is ful? crumed, (which shoe is fastened by vertical bolts 7 to the upper surface of the beam 13,)

and by means of said slots the shoe P mayv eral contact of each of the Scrapers from the eccentricity of contour of the several disks and the impracticability of spacing them precisely uniform makes it a necessity that there shall be an individual flexibility on the adjustment of each of the scrapers R. This I attain by lthe following construction: The scraper R is seated pivotally under bar L by having its inner end formed into a vertical sleeve T, held by an inner sleeve ll, provided with external annular flange l2 on its lower end, which flange extends under sleeve T and supports it loosely. Sleeve 1l is supported by its central vertical bolt 13, passed downward through bar L and provided at its lower end with nut 14, which extends radially outward under sleeve 11. Scraper R is provided with upwardly-extending lug l5, adapted to abut against the rearside of bar L when said bar is at the limit of its outthrow and the cutting end of the scraper therefore not resting against disk D. A spring S, coiled around sleeve T and locked at one end behind bar L and at the other end behind lug l5, holds lug l5 against bar L when the Scrapers are thrown from the disks; but when the scrapers R are thrown toward the disks they engage the disks D before barL has reached the limit of its instroke, and the last part of such instroke therefore withdraws lug l5 from bar L and the scrapers are held against the disks by the resultant compression of the spring S.

By obvious changes the wheels 'E can be placed on other of the disks, and by weighting the frame 2 one wheel E may be sufficient. What I claim as my invention, and desire to secure by Letters Patent of the United States,is A

l. In combination with the disk gangs C,

provided with concavo-convex disks D, a

frame 2, suitably hinged vertically at its forward end to the frame of the machine and projected backward above the inner ends of said disk gangs, friction-wheels E, suitably journaled in the rear end of said frame and adapted to have their tread upon the inner disks of said gangs on the upper portion of the convex side of said disks, and suitable mechanism for communicating the rotation of said friction-wheels to the seeding devices, substantially as shown, and for the purpose described.

2. In adisk-harrow seeder, the combination of a seed-discharging shaft in suitable relation to the seed-hopper, disk gangs, the frame 2, pivotally connected at its forward end to the harrow-frame and projected to the rear and afljustably supported at or near its rear end, shaft F, transversely journaled in the rear-end of frame 2, sprocket-wheel G, seated on shaft F, beveled friction-wheels E, seated on said shaft and adapted to have their tread on the convex side of one of the disks, near the upper edge thereof, shaft I-l, journaled parallel with and slightly below the seed-discharging shaft, sprocket -wheel H, seated thereon, a suitable sprocket-chain connecting wheels G and H, gear-wheel J, seated on shaft H', and gear-wheel K, seated on the seed-shaft aforesaid and adapted to be actuated and rotated by gear-wheel J, substantially as shown, and for the purpose described.

. 3. In a disk-harrow seeder, in combination with the seed-dischargin gshaftsuitablyseated in relation to the seed-hopper, the frictionwheel frame pivotally attached at its forward end to the frame of the machine and extending rearwardly therefrom and provided with beveled friction-wheels adapted to adjustably engage and be actuated by the disk gangs, and suitable mechanism for communicating the rotation of said friction-wheels to the seedshaft aforesaid, substantially as shown, and for the purpose specified.

l. T he combination of the sliding bar L, the scraper R, provided at its upper end with a vertical sleeve T and an upwardly-diverging lug l5 and having its cutting-surface in substantially the vertical plane of the upper portion of said lug, the bolt 13, passed vertically through the bar L and sleeve T and loosely supporting the latter, the spring S, coiled around sleeve T, with its upper end locked behind bar L and its lower end abutting against the inner surface of lug l5, and suitable means for reciprocating said bar, the parts being in such relation that when said scraper is thrown from the disk said lug will strike said bar and limit the expansion of IIO wheels E, adj ustably seated, respectively, on

the ends of said shaft, and set-screws 5, seated in the outer ends of the hubs of Wheels E, with theinner ends of said set-screws bearing, respectively, against the ends of said shaft, whereby the interval between wheels E can be varied to place the tread of said wheels to or from the center of said disks, substantially as shown.

6. In combination with the disk gangs C, provided with the disks D, the frame 2, vertically hinged at its forward end and projected backward above the inner end of said gangs, shaft F, journaled transversely in the rear end of said frame, Wheels E, seated on said axle and adapted, respectively, to have their tread on the convex side of the adjacent disk, a suitably-supported plate 3, rod 1, pivotally attached at its lower end to the rear end of frame 2 and projected upward through plate 3 and provided at its upper end with a nut, and the coiled spring 1l, interposed on said rod between said nut and plate, substantially as shown, and for the purpose described.

In witness whereof I aiiix my hand in the presence of two witnesses.
