i QPEbIFICATIQN forming part of Letters PatentNo. 252,194, dated January 10, 1882.

1 Application filed May 18, 1881. (ModeL) .To all whom it may concern Be it known that 1, CYPRIAN U. GRANDALL, a citizen of the vUnited States, residing at Sterling, in the county of Whitesides and State of Illinois, have invented certain new and useful Improvements in Corn-Planters and I do hereby declare thefollowing to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which ihappertainsdo make and'use the same, referen'c'e being had to the accompanying drawing-s,and to letters or figures of reference T marked thereon, which form a part ofthis speci-vl fication.

My invention relates to improvements in seed-planters in which perforated, rotating, 'and laterally-moving seed-plates are operated by being geared tothe ground-wheel, and in which the seedrboxes are placed upon the rear frame 'of the machine.

Theobjects ofmy invention are, first, to regulate more closely the number of seeds to be planted in one hill second, to furnish a machine -in which the operator of the dropping devices may be seen by the operator, thus enabling him to drop with greater accuracy, and also to see that the devices are doing their work. I attain these objects by means of the mechanism illustrated in the accompanying drawings,in which- Fig'u're l is a plan view, showing in a general way. the construction of the machine. Fig. 2 is a side elevation of the machine. Fig. 3 isa rearelevation of the front frame of the machine, showing the mode of operating the second drop. Fig.4 is a rear elevation of the seed-boxes and a portion of their attachments, showing the transverse shaft, bevel-gearin gs, and a portion of the self-adjusting shaft which connects the seed-plate with said bevel-gear. Fig. 5 shows the flutter-valve or second drop. Fig. 6 is a vertical section of the boot or heel of the runner, showing the position of the second drop.

Fig. 7isa plan view of the bottom of the seedbox, showing the seed or drop plate with preliminary and final cut-offs. Fig. Sis a viewof the under side of the seed or drop plate and the top-plate with its lugs arranged around the seed-plate. Fig. 9 is a front view of the final cut-oh, with the cover removed to show the sliding bars and the spring at the upper end of such bars. Fig. 10 is a front view and a section of the cover for the sliding bars in the final cut-off. Fig. 11 is a sectional view of the final cut-off through the line as :v in Fig. 7. Fig. 12 is a vertical section of the lower part of the seed box, the seed-tube, and the boot of the runner. Similar letters refer to similar parts throughout the several views.

The body of my machine consists of the two frames A and A, Figs. 1 and 2. The frame A is supported by the ground-wheels B 13, while the frame A is supported bythe runners C O and the governing -wheels D D. The two frames are united by the common hinge N and the swivel-hinge X, Figs. 1 and 2. The hinge N allows the frame A to bend downward or upward to adjust the runners O (J to the undulations in the ground when such undulations extend from side to side of the planter. The

swivel-hinge X allows the frame A to rotate upon its axis, so as to raise or lower butone side of the frame A when the runner on one side meets an elevation or depression which is not met on the other side.

' Beneath the frame A" are set rigidly the bars 9 9, extending backward toward the seat of the driver. To such ends is'attached by a hinge the rack U, which rack is forced up ward or downward by means of the pinion V and the foot-cranks o v. The driver may by means of this mechanism raise or lowerthe frame A at will. The ends of the slide-bar 2Q may be set between the cogs of the pinion V, thus locking the pinion and setting the runners GO rigidly at any desired depth. This.

jectin usingt-his arrangement is to fix the gearing which operates the dropping "devices rig-' idly, so that it may work with greater perfection than would be the case were a partof the gearing seated upon the front frame, A.

E. is a bevel driving-gear'attached to the hub of the ground or covering wheel B, and turns the bevel-gear b on the transverse shaft Gr.

and also to form a bearing for thespring k.

This shaft G is provided with the bevel-gears 0 c, which operate the gears d (1, Figs. 4 and 12. The gears d d are connected with the under side of seed-plate I I by means of the self-adjusting shaft H, which is joined loosely at its ends by means of four-sided sockets to such gears d cl and seed-plates I I, as shown in Fig. 12. When the gearing, as described, is oper ated by the motion of the ground'wlieel B thesecd-plate I is revolved .or rotated. The seedplate I is placed against the under side of the top plate, J, and on the under side of such plate J, and around the seed-plate I, are placed the lugs ffffff. When the drop-plate I is rotated its rounded corners strike the lugsff ffff, thus pushing such plate irregularly from side to side. It will be observed, Fig.8, that I place one corner less on plate I than there are lugsff, &c. This is essential to produce the irregular motion mentioned. When one lugf is met by a corner of the plate the lug opposite is between ,two corners, thus giving the plate room to slide in the direction of the last-named lug to allow the opposite corner to slide by the lug which it has met. Plate Iisprovided with the seed-holes h h h, &c., Fig.- 7. The jarring and the irregular motion of the plate I while it rotates agitates the corn continually, thus preventing it from bridging over the seed-chambers. The result is that the seed-holes are always promptly filled.

In Fig. 7, Z l, 860., are yieldingpreliminary cut-ofis, made of wire or other elastic material. When more than one grain attempts to settle into the holes or seed chambers it they cannot settle below the surface of plate I, the seedchamber being deep enough to receive only one grain below its rim. These preliminary cutoffs l i will then scrape out the grains, so that the chamber may refill properly. When the chamber is once properly filled it passes on wit-h the one grain unmolested by the succeeding preliminary cut-offs, under the final cut-off K, and over the upper end of thetube L, Fig. 12. Figs. 9, 10, and 11 show in detail the construction of the final cut-oft K.

O is a box or arch, attached rigidly to the top plate, J, and the wall of such box, which is toward the approaching seed-chamber, is inclined to the seed-plate 1,as shown in Fig. 11. The angle of such inclination which I find most advantageous is about forty-five degrees. The outer surface of this wall is provided with grooves, in which rest the sliding bars t t 'i, Figs. 9 and 11. The bars it t' are each provided with a shoulder or stop, 6, to prevent the lower'end from bearing upon the seed-plate I,

Q is a cap or cover, placed over bars -i i t and spring to hold these bars in place. Should a large grain or more than one grain bein one of the'seedchambers h when coming to the bars i t t, such bars will yield and slide backward and upward sufficiently to allow'the corn j such valve, the pawls r r, the'gate's,upo thepawls r r are fastened, the'elhdivsj in the chamber to pass. The sprin'gk causes the bars i i 93 to fall again as soon'a-s the chamber has passed. I use several bars i, because by so. doing the opening made to admit the corn in the chamber into the cut-off box 0 will be made just as large as necessary and no larger. \Vhen the corn in'the chamber comes in contact with the cut-off it does so ordinarily at but one point. By using several bars only the particular bar 11 which is met by the corn is pressed upward, while the others remain in place, thus preventing the corn outsideof the seed hole or chamber from passing through the cut-ofi", as would be the case if the whole cut-off were raised. The seed hole or chamber, after passing the final cut-off, K, passes to the opening in the lower or bottom plate, It; were the upper end of the tube L is attached. corn will ordinarily fall ofits own-weight such tube L. Sometimes, however, amay lodge in the seed-hole in such] am an" as not to fallout ofits own'weight. 'To'r this difficnlty I place the ball I loos l the chamber 0, Figs. 11 and'12. The of the seed-plate I will bring the'ballov seed-chamber h and cause its weightto al upon the corn in such seed chamber. weight of such ball P is certain to (ii the corn from the seed-hole. Tube L co n the falling corn from the final cut-off upper part of the boot M. At or near t-h tom of such boot M isfixed transversely h fan-like wheel or flutter-valve S, when the second drop. The first drop 'ahov scribed, it will be observed, is operate 4 means of gearing connecting it with thegroun'dwheel B. The second drop, on the contrary, is operated by means of the lever orcheckrower usually employed in corn-planters. flutter-valve S has the wings m m m,&c. T form troughs or chambers 141,850, V 5

Into the upper part ofthe boot M isk'fiied the vertical transverse 'part'ition p, extending down upon the flutter-valveS in such 7 p as to leave only one chamber-q ope'n atanie to receive the corn as it falls from the 1 or first drop. From the lowerend'o tition p a suitable number of wires eXte'r. ward over the flutter-valve S toke'p from falling out of the chambers'iqprein' I use wires because'they will allow'th' to see the corn as it lies in the chem fore it is discharged, thewir'esheinig just near enough together tokeep t from pa-ssing'between them.

brating bar n is seated against the frame A, near the hinge-joint, and is provided with the One movement of the vibrating bar a will revolve the flutter-Wheel S sufficiently to carry the chamber g (which has been uppermost and is filled with corn) backward far enough to bring the next chamber q uppermost, so as to allow it to receive the corn as itfalls from the seed-plate I. The chamber g which is filled with corn now rests under the wires '0, Fig. 12, and at the next movementit is revolved far enough to discharge the corn into the furrow made by the runner G and the boot M.

Some parts of my machine are not new. For that reason I have deemed it unnecessary to describe such parts in detail.
