EEDlNG-MACHINES.

February 23, 1869.

To all whom it may concern:

Be it known that I, ALBERT FRANKLIN, of Genoa Cross Roads, in the county of Delaware and State of Ohio, have invented a certain new and useful Improvement in Grain-Drills, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form part of the specification, and in which- Figure 1 represents a side elevation of the machine; Fig. 2, a similar view of the rear portion, but viewed from theopposite side; Fig. 3, a transverse section, looking toward the front through the rear portion of the hopper, and `intersecting the hopper and feed-cylinder through their hindmost delivery-openings, in` connection with which are used fixed and removable dividers for dividing the discharge, top view or plan of the rear portion, showing the hopper uncovered, and the regulating top slide covering the discharge-opening therein removed; and Fig. 5,` a plan of three such regulatingslides, having their openings differently arranged, to suit changes in the feed, as specicombined' in fied hereinafter; Fig. 6, a horizontal section of the rear portion in part through the hopper and feed-cylinder; Fig. 7, a horizontal sectional view, taken below the hopper, mainly of the rear fixed and removable divider arrangement before referred to; Fig. S, a longitudinal outside view of the feed-cylinder detaohed, and Fig. 9 a transverse section of the same.

This machine is designed to be used principally for sowing among standing corn such grains as wheat, barley, or rye, the advantages of which mode of planting with grain to the standing crop, and plowing between the-rows, are well known to farmers, and machines for said purpose have before been constructed. Other planting may also be done.

The machine represented in the accompanying dr, wings vnecessarily embraces details common in their general action and arrangements to other grain-drills, and hence only passing reference will here be made to certain The running wheel A of the machine is arranged in front, and serves to drive, by bevel and spur gear a c b ZJ', the feed-cyl- Y chine being travers yat one side to scatter inder B, which is situated lengthwise of the hopper O in direction of the machines travel. The machine is iitted with two side plows, D and E. The plow D, on the left-hand side,

has two drills, c c', in which are inserted two tubes, d d', to convey the grain to them as fed or discharged by the machine. The dirt rising in front of this plow passes between the two drills as well as on the outsides, the plow having a recess, c, behind the standard f, whichl carries the plow. The plow E, on the right-hand side of the machine, has but one drill-tube, g, behind the standard f,which carries said plow. The grain deposited through this tube is covered by the dirt coming on the landside of said plow,

of the same plow serves to cover or throw up the dirt over abroadcast distribution of grain, which is made on the same right-hand side among the hills by a spout, F, connected with the hopper, and arranged in front of the standard f, that carries the right-hand plow, E. The grain is thus planted in drills on opposite sides, and with a broadcast distributer, certain or relative proportions, as hereinafter explained, a discharge of varying amounts taking place from all simultaneously, and this arrangement I find better equalizes and improves the planting, the maed twice in a row, first down, which of course renders the one broadcast distributer, the grain among the hills on both sides. Ihe grain is led from the hopper Oto the several discharge arrangements before mentioned through inclined triangular or pointing-to-one-side openings h h, 'i

The one opening Z in the bottom of the hopper, to supply the broadcast-distributing spout F, has a fixed discharge, the regulat- Mere regulatingdischarge, I am aware, have before been used. The feed-cv]- inder B has a series of divided cells, m' m', n n), o o', rx, corresponding in number and arrangement to the discharge-openings in the bottom of the hopperthat is, as regards the longitudinal disposition of them along the cylinderthere being any number of said cells in their circular arrangement around the cylinder to each transverse division of it, Figs. 3 and 9 Ashowing four in a circular row, and each circular row of cells constituting one set, working under the same opening in the bottom of the hopper, and the several sets,7 working under different openings. The several cells in each circular row or set are of the same but the several sets m m, n n, o o,:wh'ich supply the drill-tubes, of different capacity, as shown in Fig. 6, so that when the one slideH is used the feed is through the openings h h', to give asupply, say,in connectionwith the broadcast-distributer, of a of grain to the acre. Then the slide Iis inserted instead, and the feed established through the openings il t, a sup-` ply of two bushels to the acre is given, byv reason of the receiving-cells a n', then in op-7 eration, being of greater capacity thanl the cells m m in operation under the use of the slide H; and when the slide K is inserted and the supply established through the open ings 7s 7c and 'different-sized cells o o', a discharge is produced of, say, abushel and three pecks to the acre. The feed from the receiving-cells in the cylinder to the drill-tubes cl, d', and g during the rotation of the feed-cylinder B is effected by connecting-spouts M N. The one spout, M, which supplies the two drilltubes d d on the left-hand side of the niachine, has a removable divider, S, operating in connection with it. (See Figs. l, 3, 4, 6, and 7 This removable divider nts at its lower end a notch, s, in the frame between said drill-tubes d d', and fits in its upper end in either one at pleasure of three stationary dividers, r r r2, arranged in line with or unlof cells, m no, in the feed-cylinder, to divide the grain being discharged from either one of said circular rows equally to the two drill-tubes d d', and prevent choking of the one ofeither of said tubes, one circular row of cells in the feed-cylinder thus supplying two drill-tubes.

in the hopper-bottom and their corresponding cells, m u o, in the feed-cylinder. The several cells m m', n n, o o', and r' of each circular row in the feed-cylinder correspond, as regards triangular form, to the discharge-openings h 7L', i i', 7c k', and Z in the hopper-bottom, but are so arranged round said cylinder as that their apices or points occupy a reversed position to the points or apices of the hopperbottom openings, as the cells, in the rotation of the cylinder, come under said openings during the travel forward of the machine to (See Figs. 4 and 8.) Thus it will be seen that the mechanical arrangement for supply of the feed-cylinder is of a doublewedge character-the one nxed and the other movablethe base of the one wedge (or cell) moving in advance and iirst passing the apex of the other wedge, (or hopper-bottom 0pen-,

ing,) and the apices of the two wedges gradually closing on each other, whereby the grain is drawn from the hopper in the most regular, gradual, and certain manner, without tendency to scatter or crowd at one side of the cells, so that the feed-cylinder operates more easily, and the discharge is more easily distributed. In taking the feed, the final pressure of the grain in veach cell m m', not', o o",

and TX, as it passes its supply-opening in the hopper-bottom, is toward the apex or point of said cell; but as in all seeders which are provided with a cylinder revolving beneath a concavecup or hopper-bottom the grain is liable to be caught and crushed between the two, I provide a passage-way for the surplus grain between the two, which may be located as desired, either in the hopper-bottom or in it being simply necessary to lso arrange the two parts as to leave suiiicient space between the two to allow the excess to pass. In my construction as described I Vpreferably locate the groove in the cylinder.

I form asmall crease, channel, or open connection, z, of sufficient capacity to receive, say, one grain or kernel between the apex of the one cell and the base of the next cell in the same circular row of cells, through'which channel z grain not freely passing the pointed extremities of the openings in the hopperbottom, as the receiving-cells are about colnpleting their traverse under said openings, guided and forcibly but gradually compressed into the next vacant cell in the same circular row, by the combined action of the two wedge-shaped extremities ofder the center of three hindmost circular rows l the feed-cylindercells and openings inthe hopper-bottoln closing on and passingeach other.

Thus the several cells in a row arel Having thus fully described my invention, what I claim7 and desire to secure by Letters Patent of the United States, is-

1. The combination of a hopper bottoni having triangular openings with a revolving seed-cylinder, When said openings are arranged in such relation to the cylinders that the revolution of the latter draws the seed to the apex of the former, as and for the purpose described.
