SEEDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 425,274, dated April 8, 1890.

Application filed August 16, 1389 Serial No; 320,935. (No model.)

To all whom it may concern.-

Be it known that I, WILLARD A. VAN BRUNT, of l loricon, in the county of Dodge and State of Wisconsin, have invented certain new and useful Improvements in Seeding- Machines; 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.

My invention relates to an improvement in seeding-machines, the object being to provide a light-m nnin g m achine which may be quickly transformed into a drill-seeder, a broadcastseeder, or a cultivator, according to choice.

A further object is to furnish a simple and durable machine having few parts capable of easy adjustment.

. A still further object is to provide a machine which may be easily taken apart for shipping and have its various parts renewed in case of breakage or undue wear, and in so doing to produce a machine which may be placed on the market at a comparatively slight cost.

With these ends in View my invention consists in certain novel features of construction and combination of parts, as will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation. Fig. 2 is a plan View. Fig. 3 is a sectional view through the sced-hopper. Fig. 3 is an end view of the device. Figs. 4, 5, and 6 are views of different forms of dragbar holders. Fig. 7 is an enlarged view of the gearing,and Figs. 8 and 9 are detached views of the two forms of tooth-holders.

A represents the frame of the machine, it consisting, preferably, of a pipe bent into U shape to form the sides 1 1 and the front 2. The grain-hopper, made of a pair of sloping sides 3 3 and metal end pieces 4 4, into which the sides are fitted and secured, is furnished with downwardly-projecting legs 5 5, which rest on and are rigidly secured to the rear ends of the sides 1 1 of the U-shaped frame.

' The axle 6 is looselymounted in bearings 7 7,

formed in the front legs 5 5, and the outer ends of the axle are supported in the hubs of the ground-wheels 8 8 in the usual manner. The tongue 9 is hold fast to the frame A and supported on the axle (3 by means of clip-plates 9 and 10, respectively, and the former is provided with a cap 11, on which are formed the depending ears 12 12, while the latter (plate 10) is connected with the seed-hopper, and thus partially supported by means of a strap 13. Corresponding with the depending ears 12 12, and performing the same function, are a series of different forms of drag-bar holders slightly modified to suit the different positions at which they are located on the frame. These different forms are shown in Figs. 4:, 5, and-6, and as they are slightly different a detailed 6; description will follow. The first, Fig. at, consists of a clip-like piece of metal 14, bent to encircle the frame and open at one side,where perforated ears 15 15 are formed to receive a bolt, key, or other device by which the clip is drawn together or tightened upon the frame by the turning of a nut thereon or by upsetting the bolt or rivet. Inside a feat 16 is formed and adapted to enter a hole on the under side of the frame to prevent the cap or holder from turning thereon, A pair of depending ears 17 17, on the lower end of the holders, like the cars 12 12, receive the forward ends of the drag-bars 18 18. The second form, Fig. 5, of holder is provided with a screw-threaded socket 19 to receive the end of the brace-rod 20, which braces the tongue. There are generally two of those used, one on either side of the tongue. Otherwise this form is like the firstone described. The third, 8 5 Fig. 6, is like the first in its essential parts, but, being designed for attachment to the corner of the frame, the depending cars 17 17 are proj ectedout laterally as well as downwardly,

so as to lie parallel and in line with the other 0 cars.

The drag-bars consist each of two narrow strips of metal separated a suitable distance apart at or near the middle by spacing-blocks 21 21, and spread apart at the forward end to 9 5 span the distance between two holders, so i that the adjacent ends of the strips composing the bars are pivoted between the ears of one holder. These dragbars extend backward different distances, the alternate ones :00 being short and long, so that the teeth are brought in two rows in the accustomed manner.

There are two forms of tooth-h elders shown in Figs. 8 and 9, and they will be described in order. In Fig. 8 it consists of a casting having a socket 22 in one side to receive the double diamond-pointed tooth 23 and a boltand preserve it from wear or injury until the tooth is reversed. The casting or holder is provided with two elongated and

slightlycurved slots

29 and 30, which extend about at right angles to each other. These are intended to receive the bolts by which the holders are adjustably and yieldingly held to the drag-bars. The slot 29 admits of its being pivoted at different inclinations to the dragbar, while the slot 30 allows .the holder to yield in case the tooth is struck by astone or other obstruction. A spring or other device could be connected with the holder to insure its recoil into proper place after being struck. The other form (shown in Fig.9) is substantially the same, but instead of having the two slots it merely has an opening to re ceive a bolt upon which it is supported, and

it has a pair of internally-toothed parallel curved jaws 31 31. These have a link 32 inserted between them at different positions, and the forward end of each link is loosely connected with a vibrating lever 33, pivoted on the drag-bar, and the opposite end of the .lever is pivotally connected with a springactuated slide-rod 34, which is loosely held at one end in aloop 35. By this means the teeth are made yielding, but they are made to regain their normal positions upon being released.

The axle 6 has mounted thereon several levers 36 36, the one on each side of the tongue of which are-bell-crank levers. These levers are all ad j ustably secured in place by means of set-screws 37 37. The rods 38 38, pivoted to the drag-bars, extend loosely through the sockets 39 39, swiveled to the outer ends of these levers. Spiral springs 40 40, mounted loosely on the rods, keep them yieldingly depressed, and keys 41 41 hold them in the sockets.

The axle is oscillated by means of a compound lever. The main portion 43 of this leveris pivoted atits lower end to the rounded segment 43, which is vertically supported on the tongu'e'. This segment is provided with a stop 44 on one side, which limits the forward movement of the lever, and with teeth 45 on its opposite face, with which the latch 46 engages. These teeth extend along only a portion of the segment and the balance is smooth, with a notch at the end to receive the latch. The outer rounded edge 47 forms a track upon which the toothed segment 48, se-

cured to lever 43, rides in its oscillations. A sleeve 49 is formed at one end of this segment 48 to receive the latch, and a spiral spring therein forces the latch outward. A secondary lever 50 is pivoted near the lower end of lever 43, and this lever also is furnished with a spring-actuated latch adapted to engage the teeth of the, segment 48. The levers are both bent backward to bring the handles 51 at their ends within easy reach, and the usual means for operating the latches is provided. Connecting-rods 52.extend from the lower end of lever 50 to the bell-crank levers 36 36, and by this connection the axle is oscillated when one or both of the levers are swung. By means of the levers it is possible to sow the seed at a great variety of depths, as the distance raised or lowered by one-half of either lever is about one-half of the distance the teeth may be raised or lowered with a full sweep of both levers. To accomplish this with a single simple lever the sweep would necessarily be so great that the lever could not be handled. I V

The seed hopper is braced through its middle by means of bracket-plate 53. This plate has flanges at its edges, by which it is secured to the sides of the hopper, and is ribbed to give it strength. A pair of trussrods 54 54 extend from theends of the hopper downward beneath this plate to give sup-- port to the hopper at the middle. The rods may be tightened by turning the nuts 5555 on their ends. Several grain-cups 56 56 are secured to the bottom of the hopper, and to these the spouts for distributing the grain are removably secured. Either broadcast or drill spouts may be used. The force-feed wheels 57 57 are mounted on a shaft, whereby they may be shifted endwise through the cups to feed more or less grain, asrequired, and the guard-plates 58 58 limit the size of the discharge-opening for the grain. A pinion 59 is mounted on this shaft and adapted to turn the force-feed wheels at the requiredspeed. A plate 60, having acollar 61, which is loosely mounted'on a hub 62 on the end plate of the hopper, depends and carries a smaller hub 63 atits lower :end, upon which a gearwheel 64, which meshes with and drives pinion 59, turns. This gear-wheel is normally held in engagement with a similar wheel on the axle, which by means of a spring 65 andthe gear-wheel 66 is rotated with one of the ground-wheels, with which it is connected. This spring 65 is secured to a lug on the plate 60 and bears against one of the legs of the hopper. A lug 67 on one of the legs limits the forward movement of the loosely-mounted IIO plate. A short cam-lever 68 on the axle back of It is evident that slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the particular construction herein set forth; but,
