yIn the drawings like characters of reference indicate corresponding parts in eachiigure.

A is the seedbox, and B the end castings, one only of which is shown.

C is the bail, the end bars c of which 'are suitably pivoted on the end castings B.

D is a T-shaped angle-bar which extends crosswise of the machine andl is securely bolted to the end casting B, as indicated.

E is a bracket which is securely bolted to v the cross-bar D substantiallycentrally.

F is a knee-strut which is Securely bolted at the rear to the depending leg e, attached to or forming part of the casting E, and at the front end is provided with a notch f, extending from the upper ledge downwardly. The front end is bent as indicated and is secured by the bolts f to theeXtension-piece F', which is securely bOltedQbyl the bolt f2l to the front cross-bar o f ...the angle-i ron frame 2. The extensionpiece, anotch f3, which extends fromthe botto edge upwardly. The two notches fhandff'form a hole, which forms a bearing fortherod G. The other rodl H eX- tends througliifahole f4 in the extension-bar F. The'bars G and H are journaled in suitable bearings on the ends of the angle-iron mesh with each other, as indicated.

frame 2. Bothbars Gr and Hare operatively.,

connected by the quadrants g `and nwhichg is an arm secured on the end of the bar Gf? and g2 is a lever 'pivpted on the 10015l gs Lt-tha@ rear of .the axle and having the upper enex;

g2 is providedwith afsuitable handle, whichlies ;'105 closely to the end of the seedbox,being dee t.,

' to enable it to be drawn out from between the teeth, and thus provide for the adjustment of the lever in order to produce the desired movement to the bars Gr and H, so as to draw the alternate drill-shoes Jforward or backward, and thus change the angular position of each drill-shoe in relation to the neighboring shoe.

I represents drag-bars which are suitablyl connected to the bars G and H.

J represents the pressure-bars, which are suitably connected to the drag-bars and extend up through the socket-brackets j, secured to the cross-bar C of the bail in the usual manner.

Wev do not describe the means of connect-l ing the pressure-bars to the drag-bars, nor do we describe particularly the socket-brackets connected to the bail, as they form no feature in our invention.

K is a spiral spring which encrcles the pressure-bar J and is held between the socketbr'acket j and the stop L. rlhe stop L is provided with an upwardly-extending portion l, ashoulder Z,'intermediate of its length, and a teat Z2, which is designed to extend into a hole 7c in the pressure-bar. A loop Z3extends from the shoulder around the pressure-bar, as indicated, and is designed to hold the stop onv the bar. There are several holes placed in the pressure-.bar J, and in order to vary the ,pressure on the drag-bars it is simply necessary to push up the spring K beyond the upper end of the stop L, whereupon the stop may be swung outwardly away from the bar and the teat .7,2 inserted into the next hole either above or below, or as may be desired, to produce the desired pressure upon the drag-bars.

The bail C is'raised or lowered by the following means: e is the fulcrum-shaped spindle, which is suitably formed at the end and bolted to the angle-iron cross-bar D. l' is an arm provided at the rear with double bearings e2 e2, intermediate of its length with the quadrant e3, and at the forward end with the boss e4, through which extends the cross-bar D of the bail. @5 is a square bar which is round at the ends and journaled at the rear end in the bearing-bracket M and at the front end in a bearing in the bracket E. N is a quadrantal gear secured on the bar e5 and meshing with the quadrant e3 in the arm E. M' is a quadrant attached to or forming part of the bearing and provided at each end with the teeth m and m2. m3 is a lever secured at the rear end of the bar e5 and provided with a suitable plunger mi, which is designed to coact with the two sets of teeth of the quadrant. It will be seen by manipulating the lever or throwing the lever in the direction indicated by arrow, so as to engage with the teeth m', that the quadrantal gear N will throw the arm E, and consequently the bail, downwardly. As the drag-bars also are neeeSSarily thrown downwardly, the depth at which the hoes are inserted will oi course depend on the position in which the quadrant is placedin relation to the teeth ym. By throwing the lever in the opposite direction, so as to engage with the teeth m, the quadrant N, engaging with the quadrant a, throws the arm E' upwardly, and consequently the bail and drag-bars upwardly, the distance depending, of course, upon the position in which the lever is placed upon the teeth la.

It will be noticed that in the means hereinbefore described of raising and lowering the bail the power is applied between the bail and the fulcrum, and as such fulcrnm is on a line with the pivot-point of the bail wc are enabled to lift the bail with ease and more advantageously than by any means of which we are aware.

O is the pole, which is suitably bolted to the pole-block O. The pole-block, it will be noticed, is bolted to the cross-bar D by bolts (l, is linee shape in form, and provided with a central opening o', whereby such pole-block is made to straddle the gear-wheel l on the driving-axle 3.

The frame 2 is connected at the rear end to the bearing-casting 4, upon which the seedbox is supported and through bearings in which the axle 3 extends. The bearing-casting 4 is connected at each end by the braces 5 to the cross-bar D. 6 represents diagonallyplaced braces, which extend through the sides of the pole-block at one end, being` held in place by nuts, and through the bearing-casting l at the opposite end, being held in the bearing-casting by a nut, as indicated. ',lhe bracing-rods 6 serve to brace the pole-block to the frame.

The gear-wheel l) is a face gear-wheel of the usual construction adopted in this class of machine.

Q, is a divided sleeve which is secured together through the lugs q by bolts q. (f is a groove formed between thelugs, and q is a step formed on the opposite portion of the divided sleeve, as indicated. The step q" forms a bearing for the lower rounded end of the spindle p, which carries the gear-pinion M, which is driven by the gear-wheel l), so as to rotate the spindlep and drive the feed-run spindle R by a means which it is not necessary here to describe, as it forms no feature in our invention, nor is it necessary for a like reason to describe the radial adjustm cnt oi the pinion p.

The gear-wheel P is held in contact with the gear-pinion p by means of a spring p, which presses against the hub of the gearwheel P and against a collarjf on the driving-axle 3. The gear of course is secured to the shaft so as to rotate therewith, but is longitudinally adjustable thereon. The sleeve IOO IOS

IZO

consequently the rod Q2 raised, the collar angle turn g5, such extension-arm Q, hereinbefore mentioned, is secured to the shaft, and inside of the sleeve next the gearwheel is located a collar Q', which has an extension-arm g4,- having a substantially rightg* extending through the groove g2.

Q2 is a rod suitably secured at one end to the bail C. The other end q is enlarged and p'rovided with an inclined edge g'. It will now be seen that upon the bail being raised, and

Q will be forced lengthwise on the shaft against the tension of the spring p2, and consequently throw the gear-wheel in'the direction indicated by arrow, and thereby throw such gear-wheel o'ut of mesh with the gearpinion p'. upward adjustment of the bail the gear-wheel and the parts driven by same will be automatically-thrown out of gear.

The grass-feed-run shaft R is driven from the lInain axle from a sprocket-pinion R', connected to a suitable sprocket-gear on the grassseed shaft by a sprocket-chain r. Itis of course necessary to provide means for throwingsuch sprocket-pinion out of and into driving connection with the main axle, and to effect this we provide a toothed clutch 7"', which is designed to engage with =a pin r2, extending through the shaft. We also provide a bellcrank r3, which is pivoted on a bolt r4 on the cross-barD and has a forked lower end r, each member of which extends down on each side of the hub of the sprocket-wheel R', as indicated. The opposite end of the bell-crank r3 is provided with a thumb-latch r1", having an eccentric end, such thumb-latch being pivoted on a pin r, extending through the end of the bell-crank and through the cross-bar D.

On the bolt r* we secure a double arm r', one

end of which extends up underneath the anglebar D and the opposite end of which extends the lower arm of the bell-crank r3 to the rightangular projection Q5 on the end of the arm g4.

It will now be seen by throwing the thumblatch rw in the direction indicated by arrow that the bell-crank will be tilted on its pivoty,bolt r4, and thereby throw the sprocket-wheel R' longitudinally on the shaft, so as to throw the toothed collar 1"' out'of engagement with the pin r2, extending through the'axle 3. At the same time the rod 8 will, by reason of its connection to the arm q of the collar Q', throw the gear-wheel P out of mesh with the gearpinion 10', connected to the feed-run. It will consequently be seen that both the drives for the feed-run R and the grass-seed shaft RX` Ythumb-latch back into the normal position` It will thus be seen that upon every By throwing the sprocket-wheel R' will be operatively con? nected to the axle.- We can also throw the gear-wheel alone out by hand by means of the arm S, which is journaled on the'stud q", forming part ofthe sleeve Q. The arm S is provided with a cam-shaped end s, which is designed to come vin contact with the outwardly-projecting lug Q3, forming part of the collar Q',"and by this means when the arm is turned it throws the gear-wheel away from or close to the gear-pinion p'.

In order to hold the turnover gate or plate T in position, we provide the following'simple device: The turnover plate T is provided with the end pivotpins t, attached to or forming part of the same. One end pivot-pin textends into a notch t' in the side of the hop-55 I per. t2 is a groove which extends longitudinally of the hopper through the notch t', and t3 is a pin or rod which is placed in the groove t2 and extends through the notch t' and over the pin t, and thereby holds the turnover plate securely 'in place, and yet provides a ready means when the pinor rod t3 is withdrawn to remove the turnover plate.

U represents the'wheels of the double-feed run,'and V the gate-valveI of the feed-run, which is secured on. the square rod o and isr provided withhubs V', whereby such gate is journaled in the walls.

'u' is a lug or stop extending from' the side of the feed-run, and c2 is a sleeve on the rod o, such sleeve being provided with a projection o3, which is designed to come in contact with one or other of the ends of the lug lo', (only one end of which is shown.) The sleeve e2 is provided with a handle et for manipulating it.

of is a spiral spring surrounding the rod 'v and extending between the sleeve v2 and a collar o on the shaft. By pressing the handle toward v the spring the sleeve may be moved longitudinally, so as to release the lug 'v3 from the lugv o', whereupon the rod c may be turned, by means of the handle, so as to throw the gate V to the reverse side to that shown in- Fig. 11. By this means it will be seen that 2. In aseeding-machine,thecombination with'the bailand the'drag-bars connected to TOO IIO
