LISTERl CORN-DRILL.

SPECIFICATION forming part of Letters Patent No. 613,525, dated November 1, 1898.

Application iled February 18, 1898. Serial No- 670,858. (No model.)

To a/ZZ whom it Webby 0071.067171.:

Be it known that I, JAMES ALEXANDER PAT- TERSON, a citizen of the United States, residing at Clifton, in the county of Clay and State of Kansas,have invented certain new and useful Improvements in Lister Corn-Drills, of which the following is a specication.

My invention relates to improvements in two-row lister corn-drills in which each of the two sections is complete in itself; and the objects of myimprovements are, iirst, to provide an easily-operated two-row-lister corndrill wherein the carriages are connected by au automatic adjusting device; second, to avoid the difculties heretofore experienced in the irregular movementof such machines by reason of their traveling upon the uneven surface of the ground, and, third, to provide' a steady, simple, and effective device for actuating the seeder. I attain these objects by means of the mechanism hereinafter described, and illustrated in the accompanying drawings, in Which- Figure l is a plan of my invention complete with the exception of one bob; Fig. 2, a section of the adjustable frame, showing the mode of attachment thereto of the coveringshovels n, lever-standard m, and the plate g, with the hoe or furrow-opener h secured thereto; Fig. 8, the carriage-frame, showing attached standard-support and gearing for operating the seeder; Fig. 4, the automatic adjusting device by means of which the two carriages are connected.

Similar letters of reference indicate like parts throughout the several views.

As the two sections of the drill are exact duplicates of each other, a description of one will serve for both.

Each carriage consists of a bob A a, frame b, axle s, and wheels u. j A second frame f extends around the sides and forward end of frame b and is pivoted thereto at e c.

To the rear end of adjustable frame f are secured the co\*eringshovels 'n by means of bolt 0 and break-pin p. A plate g connects the ends of the frame f near the rear thereof. Near the middle of plate gis attached the hoe or furrow-opener h by means of rivets 'it' and break-pin j.

An ordinary ratchet-segment and lever lo are secured to the carriage-frame b and pivotally connected by arm q withthe standard m,attached to the adjustable framef,by means of which the depth of said hoe and shovels is regulated.

A seed-hopper is affixed to the carriageframe b, with the feed-pipej2 extending down just in the rear of the hoe h. Bevel-gear o, rmly secured to the axle s, meshes with the bevel-gear w, secured to the rear end of shaft t. To the opposite end of said shaft is secured the bevel-gear which meshes with another bevel-gear in the bottom of the seedhopper, thus actuating the rotary drop.

In the drawings is shown the rear end of carriage-frame b firmly secured to a rectangular frame r, through the rear extensions of which are provided journal-bearings for the axle s,and through the front cross-beam passes the shaft t. The same object would of course be accomplished by further extending the rear ends ofthe carriage-frame b, providing for journal-bearings through the .same for the axle s, and securin g a cross-beam -to said frame, through which the shaft might pass in the same manner, as shown.

If desired, weed-cutter knives may be attached to the adjustable frame fat Z. The forward end d of the carriage-frame b is pivoted to the bob at c, thus permitting the free lateral motion necessary in turning the machine.

The runners to bob A a converge toward the front till the forward ends unite, as shown, thus causing them to remain in the middle of the furrow and guide the machine. A vertical extension to the forward end of the bob is pivotally connected to the machine both from its top and approximately on a level with the carriage-frame b at c, as shown. The power being attached near the top of said vertical extension, the draft to the machine is thus equalized.

Near the rear end of each of the carriageframes b is firmly secured the bracket standard-support y z, provided with an eye through which is inserted one of the vertical standards supporting the automatic adjusting bar or pipe B. Each vertical standard rests upon a cross-bar secured to the frame b and is provided with a pivot extending into said crossbar, thus forming a pivotal connection between the two sections of the drill. One end of the pipe or bar B is firmly secured to one of the vertical standards, while the other or opposite end passes through a sleeve firmly secured to the other vertical standard. Straps around each end of said sleeve extend below the same and are provided with bearings for the antifrictional rollers D D, said rollers rising just above the lower inner surface of said sleeve and forming an antifrictional bearing for the pipe or bar B, thus preventing binding either from the drivers weight or tilting of the machine. It will readily be seen that the two sections of said drill are thus left free to automatically adjust themselves to the varying distances between the rows. The bracket standard-support 'y z being iirmly secured at its lower ends to the carriage-frame b and the upper ends converging till united, in conjunction with the vertical standards and connecting-bar, also serves to steady said frame b and prevent the same from tilting. The drivers seat C is secured to the said pipe or bar B.

The wheels u travel in the rear of and in the path made by the shovels n, thus having a reasonably level road-bed, and thereby avoiding the tilting and jolting of the drills ordinarily experienced with the machines heretofore in use, which frequently caused them to diverge from the furrow and to feed and plant very irregularly.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A two-row lister corn-drill consisting of two sections connected with each other by means of an automatic adjusting device consisting of a horizontal pipe or bar having one end rmly secured to a pivotal standard, while the other or opposite end passes through a sleeve also secured to a pivotal standard and provided With antifrictional rollers which form a bearing for said connecting-bar, substantially as shown and described.

2. In a lister corn-drill provided with a carriage-frame, the combination therewith, of the adjustable frame extending around the sides and forward end of said carriage-frame to which it is pivoted and provided with a hoe or furrow-opener and covering-shovels attached thereto, the depth of which is regulated by means of a lever, substantially as shown and described.

3. The combination with a lister corn-drill provided with a carriage-frame, of the bob consistingof the two runners the front ends of which converge till they unite, the vertical extension of said front ends pivotally connected with the forward end of said carriageframe, both from the top of said extension and approximately ou a level with said frame, substantially as shown and described.

4. In a two-row lister corn-drill provided with carriage-frames adj ustably connected with each other by means of a horizontal pipe or bar. supported by vertical standards, the bracket-supports to said vertical standards diverging and secured to the sides of said carriageframes for the purpose of preventing tilting of said frames, substantially as shown and described.
