GRAIN- DRILL.

SPECIFICATION forming part of Letters Patent No. 223,470,`dated January 13, 1880.

Application filed October 23, 1879.

To all whom it may concern Be it known that I, JAMEs S. BoGLE, of Springfield, county of Clarke, State of Ohio, have invented a new and useful Improvement fin Grain-Drills, of which the following is a full, clear, and exact description, reference being had to th'e accompanying drawings, maliing part of this specification, in which- Figure 1 is a perspective view of' a graindrill with `my improvements applied. Fig. 2 is a side elevation, and Fig. 3 a rear elevation, of the same. Fig. 4 represents a vertical longitudinal section through the same. Fig. 5 is a Side elevation, showing the gear-cover removed, With one of the interchangeable gears also removed and shown in reversed perspec` tive View, Fig. 1I. Fig. 6 is a perspective view of a-portion ofthe grain-box inverted, with one Fig. 7 is asimilar View of the distributer-casing detached. Fig.- 8 shows, in side elevation and in perspective, the bracket or hanger and quarter-box for holding the distributer-easing and adjusting Fig. 9 is a side elevation of one of the distributers. Fig. 10 is a perspective view of the inner face of one of the distributer-casin g plates. Fig. l1 is a perspective View of one of the interchangeable gears. Fig. 12 is a side elevation of the gear-lever and cam-yoke; Fig. 13, a similar view of the cam and cam-plate. Fig. let represents a section through one end of the lifting-roller shaft. Fig. l5 is a perspective view of the pivoted funnel or cup intermediate between the distributer and the conductor and drill-tube. Fig. 16 represents a modification in the devices forv locking the beams through which the hoes are adj usted.

Similar letters of reference denote corresponding parts wherever used.

The invention relates to a novel construction of the distributers, and to a novel means for securing them to the grain-box and for retaining the rock-shaft through which the gages are adjusted in position; also, to a novel method of changing the speed of the distributer-wheel shaft Without the aid of extra gears and without change of centers or any adjustment of parts; to the means for raising the hoes or teeth, whereby a backward thrust of the lifting-lever is made to rock the liftingroller upward and forward past its pivotal.

center, adapting` it to suspend the hoes or justment of other parts, while at the same time the cam is made to so fill the lever-yoke as to prevent slack or lost motion ot' the levi-r; to a novel means for suspending the tube-tops or tunnels from the distributer-casin gs, facilitating their adjustment, removal, Src.; to a novel arrangement of pivoted angle-board, which, by a slight rocking movement, is adapted to deposit the grass-seed either in front or in rear of the hoes, as desired, and to the means for holding the hoes or teeth in position when arranged either in single or double rank, all as will be explained.

In the accompanying drawings, A represents the frame of the machine, B B the carrying and driving wheels, and() the grain-box, said parts being constructed and arranged in any usual or preferred way.

The wheel B has a spur-gear, a, connected with it, from which motion is imparted to the distributer-wheel shaft, as follows: Dis a gearlever and yoke, pivoted at its forward end to and turning on the axle b ot' wheel B as a cen-` ter, the rear end of' said lever being expanded in width and provided with an irregular slot, in which a cam, hereinafter described, on one end of the lifting-roller shaft works for raising and depressing said lever. of this lever D is provided with a stud-shaft, upon which is mounted a rtransmitting gear or pinion, a', which engages with the ceiving motion therefrom.

rlhe outer end of the hub of wheel a has a clutch-face formed upon it similar to that shown on wheel a3, Fig. 1l, adapting it to engage a similar clutch on the inner end of the hub or wheel a2, mounted and turning on the same stud-shaft' with wheel a', said.wheel a2 engaging and driving wheel a3 on the distributer-wheel shaft. In Figs. 5 and l1 this wheel a3 is shown removed from its shaft, its posigear a., re-

The outer face Ioo - nal ribs e e, giving it a clutch form, adapting tion when in use on said shaft being indicated by the dotted lines in Fig. 5.

The distributer-wheel shaft E nas secured to its end a rounded extension, E', (see Figs. 1 and 3,) forming af' jrnal which has its bearin gin a sleeve-box, (lijformed in the end standard, G, of the grain-box.

The outer eri/d of journal E has longitudiit to receive and be rotated by the wheel a3, which has a corresponding clutch-face on its hub a". (See Fig. il.)

Y The clutch-faces of wheels a2 and a3 are formed alike, adapting the wheels to be transposed, and being of different diameters, by simply transposing them the speed ofthe distributer-shaft will be changed from a slow to a faster movement, and vice versa, for adapting the machine to sow small or large grain without the aid of extra gears, change of centers, or any adjustment of parts.

The gears c2 a3 when in place are held on their respective shafts by the removable gearcover F.

The gear-lever has an irregular slot, D', in its rear end, forming a yoke, and an irregular heart-shaped cam, d, on one end ofthe liftingroller shaft moves in said slot for actuating Athe gear-lever.

The expanded end of the lever D moves in close proximity with the side frame-bar on its inner face, and the cam dhas acheek-plate, d', on its outer face, outside of said lever, which serves to steady the movement of the lever and prevent its lateral displacement.

The lifting-roller is made in crankl form, composed of the transverse rod or bar G, connected to crank-arms Gf, which at their inner or pivoted ends are provided with sleeve-journals rocking in suitable bearings on the main frame. These sleeves are divided into two parts, g g', the part g in each case being formed upon or rigidly connected with one of the crank-arms to, the adjacent ends of said parts g g/ of thel G, and the part g on one side being rigidly connected with the cam d and upon the other side with a gear-wheel, h, hereinafter referred sleeve in each case having clutch or rose plates g2, (see Fig. 13,) permitting their relative ad- 5o justment in the one case for varying the throw ofthe cam d, and thus compensating for any inaccuracies in the construction or adjustment of other parts, and in the other case for regulating or adjusting the throw of the liftinglever. rI he two parts are held in each case at the desired adjustment by a through-bolt, g3. The adjustable gear-wheel h on one end of the lifting-roller shaft engages with a second gear-wheel, h', mounted on a stud shaft, fi, formed upon or secured to a bracket, I, attached to the frame, the wheel h having a lever, H, rigidly connected with it for rotating it and imparting motion to'the wheel hand to the lifting-roller G, connected therewith.

By this arrangement of gears interposed between thelever and the lifting-roller they are made to move in opposite directions, the lever being moved backward and downwardv and the lifting-roller upward and forward for raising the drill-teeth, the lifting-roller in this movement bein g adapted to be thrown forward past its pivotal center against the grain-box or other suitable stop, in which position it is sustained, holding the hoes or teeth out of the ground without the aid of a pawl or catch.

The same action of the lifting-lever rocks forward and downward the cam d on the opposite end of the lifting-roller shaft, and said cam, acting upon the gear-lever or yoke D, depresses the latter and throws the gear-wheel al out of mesh with ythe Wheel a3, thus throwing the distributer-wheel shaft out of action and stoppin g the discharge of the grain.

A reverse movement of the lifting-lever lowers the drill-teeth into the ground and throws the wheel c2 into gear with wheel c3, again setting the distributer-wheel shaft in action.

The forni and arrangement of the cam d in its yoke is such that it acts at the beginning of the throw of the lifting-roller for raising the drill-teeth and near the end of its throw in lowering the same, thus effectually preventing the Waste of grain. I

The construction of the distributer-wheel casing andthe manner of attaching the same to the bottom of the grain-box is shownin the detail views, Figs. 6, 7, 8, 9, and l0. K represents the casing made .in two parts, in the usual form, except in particulars which will befdescribed.

The discharge-openingis protected in front and in rear by wind-guards 7c, formed one 'upon each part of the divided casing, and projecting in parallel lines, or thereabout, on the same side of the casing as the discharge-outlet, and in front and rear thereof, forming, in connection with the casing, a spout or passageway closed in upon three sides and protecting the grain from the action of the wind in its passage from the distributer to the conductor The upper\end of the casing is provided with flanges 7c k2, through which it is secured to the grain-box, on the one side by screws andTi upon the other by a bracket or hanger, L. This hanger islsecured in place by screws, and has a socket formed in it at l, for the reception of the tapering lug or ange 7a2 on the casing, the arrangement being such that after the several distributer-casings have been secured in place they can be readily removed and replaced or renewed when required withf out disturbing the hangers L, the latter serving to determine their position with precision.

The casing has an arm formed upon it, in which is formed a half-bearing at k3 for the reception of the rock-shaft M, by means of which the gages regulating the discharge of the grain are adjusted, and the bracket or hanger L has also an arm, l', overhanging the shaft M, and provided at ZZ with a quarter-bearing for said shaft, which forms an extension of the half-bearing k3, and serves to hold the shaft roo IOS

IIO

snugly thereon. By this arrangement of the bearings in the casin gand their hangers, united as described, any binding or cramping of the shaft,`such as is usually consequent upon the wa-rping, 85e., of the grain-box, is avoided.

One part of the divided casing or shell (see Fig. l0) has afunnel-shaped hopper or seedcup formed in it, and at the side of this, adjacent to the distributing-wheel N, there is a rabbet in the forward wall of the funnel or hopper at K, forming a depressed seat for the flange of the feed-wheel in such manner as to bring theinner face of the ange into the saine plane with the front and lower wall of the seed-cup in the shell or casin g plate.

The rear wall, K2, of the seed-cup projects laterally within the iianged feed-wheel N,`and is notched or cut away at n, to form a passageway for the flange on the wheel.

The foot or swinging end of the gage m swings in and out behind the lower end of this wall K2, regulating the size ofthe channel in the feed-wheel, or between the gage and the flange of the wheel, being adjusted by means of an arm, m', made adjustable on the rockshaft M by means of which the series of gages can be simultaneously adj usted for controlling the discharge of the grain as desired.

The gages are pivoted at m2 in suitable lugs on the casing-plate at points in rear of and above the distributer-Wheel shaft, the lower face of the gage acting as the upper wall of the feed-channel, and serving, by its adjustment, to change the size of said channel without materially changing its form, and causing the heel end of the gage, under all adjustments, to strike the grain to the capacity of said channel.

The casing-plates are provided at their lower 'eiids on opposite sides with conical spurs or pivots 7c4upon which the tube-top 0 (see Fig. 15) is suspended. This top is made in funnel shape, with a large open mouth at its upper end, surrounding the wind-guards of the distributer at their lower ends, and tapering thence down to the size of and itting at their lower ends Within the upper end of the ilexible conductor-tubes suspended therefrom in any usual manner. The upper ends of these tube-tops have each a flat spring, p, secured to it, surrounding said end, except in front, where it is recessed or cut away, forming lugs or ears at o, which overhang the pivots kl, said spring p being provided near its ends with perforations or eyes p', which fit over the spurs or pivots 7a4, suspending the tube-tops therefrom, and permitting their longitudinal vibration to accommodate the position of the `.hoes or teeth, whether arranged in single or in double rank.

The ends of the spring extend slightly forward of the eyes p', forming convenient handles, p2, for edecting the adjustment of the spring in applying or removing the tubetop O.

C3 represents the grass-seed box or hopper, arranged by preference in front of the grain-box, and having end pieces in one piece with and forming extensions of the end boards of the grain-box, lat shown, though-they may be made separate and removable, it' desired. By preference, also, I pra ide the bottom of this grass-seed hopper wh a series of forcefeed distributers, Q, similar to those on the grain-box, but smaller, and proportioned to the seed to be operated upon, the shaft for operating the distributer-wheels thereof being connected with the Wheel a5, and receiving motion from the wheel a through the transmittingpinion a4, in a manner that will be readily understood. Underneath the discharge-outlet to the distributers Q is arranged an an gle-board, R, made in V shape inverted, as shown in section in Fig. 4. This board extends transversely of the frame, and is supported upon a pivot, r, upon which it has a slight rocking movement, sufficient to throw its apex either in rear or in advance of the discharge-outlets in the distributers Q, according as it is desired to deposit the grass-seed in frontof or behind the holes or teeth. A shouldered spring-pawl, r', serves to hold the angle-board in either posit-ion.

S S represent the hoes or teeth, connected alternately, by means of drag-bars S', to two rocking parallel beams, T'T, at their lower swinging edges. These-beams are pivoted at their upper edges in the side bars of the main frame, and are provided at one end with one or more ratchet disks or segments, t t.

U is a weighted dog or double pawl, the long Weighted end of which serves as a handle or lever for operating it. Said dog has two teeth or pawls, a u', arranged opposite or nearly opposite each other, as shown, one engaging with teeth on the ratchet disk or segment t, and the other with those of the disk` or segment t. The rocking beams are designed to be adjusted by hand, and when released from the dog U and rocked in such manner as to bring their lower edges together, as shown in Fig'. 4, the several drill-teeth will be brought into the same transverse line, in single rank, in which position only the rear beam need be locked by the dog U, as the drag of the hoes upon the forward beam,T, will hohl said beam rocked back against the beam T. By rocking the beam Tv back and the beam Tl forward, separating said beams, the teeth will be thrown into a zigzag relation or double rank, in which position only the forward beam, T,.need be locked by the dog U against the drag of the hoes connected with it. Separate pawls t2 t3 (see Fig. 16) may be employed for locking the beams T T' in the desired position, or they may be used in connection with dog U, if preferred. -S

The hoes or teeth are connected bychains V with the lifting-roller G, the operation otl` which has been described above. Parts of the machine not particularly described may be constructed and arranged in any usual or preferred manner.

I am aware that a single perforated spring IOO IOS

the weighted has been used on one side of a tube-top in connection with a perforation or'hook on the other side of the tube-top for attaching said tube to the casing. This I do not claim.

Having now described my invention, I claim- 1. The distributer-casing provided with the dan ges through which it is secured to the hopper, in combination with the separate retaining bracket or hanger L, substantially as and for the purpose described.

2. The casing-plate and its retaining bracket or hanger, providedeach with partial bearY ings for the rock-shaft by which the feedgages are adjusted, substantially as described.
