Be .itknorvn that I, SANFORD BncKwITH, of lthe, cityot' Oshkosh, county of Winnebago, and State ofWsi cousin, have invented anew and improved Se'edngMachine; and-I do hereby declare that the following is a full and exact description thereof, reference beinghadto the 'accompanying drawings, 'and to the letterscf' reference marked thereon, the same mallcing a part of these speciiications, in which- Figure lis aperspectivc view. i

Figure 2 is a verticalsection.

Figure 3 is a fragment of a longitudinal section.

Figure 4 is aperspective vien.r ofthe cup m): m is a vertical se'ctiorrof fig.V 4; f is a bearing for the shaft r', figs. 2 and 5. i l l Figure 5 is-a perspective view 0fthe screw-cylinder d.; f is an-end view,'showing'the terminal shape of the screw-threads at f. l A l Af Y l t Figure 6 is a front elevation of the back or part .Zmofjthe scattering-tubes.

Figure 7 is a front elevation ofthe front onpartkof the, scatteringtuhes';`l cis a vertical sect-ion of the top, l" 7c a vertical section ofthe centre, andl"4 c" a vertical section of the bottom off the scatteringtube Ik, seen also-in figs. Zjand 3; hra-g. 6, are slotsfthat admit of al vertical adjustment ofl Z relative to lc; nn, in lc, are ea'rs with bolt-holesfor securing l and 7c to the axle a, as seen in figs. 2 and 3; ting. 6, is ahalf conical shape; the bottom horizontal shape may be seen at Z" the vertical shape maybe seen at l, figs. 2 and 8. Figure 8 is a fragmental view in perspective of a s'eries of adjustable caps or cut-offs, seen in fig. 1, and at e in figs. 2 and 3; z'zis a longitudinal sliding frame; 2" r are supports' permanently secured to the bottomedge of the-seed-box, and hold the sliding frame to service. Y 7

l Figure 9 isv an enlarged view of the lag and cultivator-tooth, seen inlg. 2, with mode of adjusting and securing thetooth relative to the lag; gisa rod or metallic connection between tooth o and lagp; -Sis a hookbolt, and is the medium through which the tooth o is securedand adjusted to the rod q. E. is a view of the hook-bolt attached to a fragmentrof tooth o. The outer third of the rod q is bentto a circular form, correspond ing with the radius descri-bedffrom itsconnection with thelagp bythe tooth o a is an axle; c c is a horizontal frame; b is a seed-box b is ahopper to seed-box. i

The purpose of this .invention is to provide a more uniform, reliable, and eiicient means of feeding the grain tothe scatter-er, or to aUdrill-deliveryf-and toV provide a scatter-cr that is adjustable, and that maybe equally 'well adapted to either wheat or oats,V p Y l The novelty of this'invcntion consists in thel employment andadaptation of certain devices and their use jointly, and in combination with the seed-'b ox, shaft, and other `auxiliaries of a seeding-machine. The shaft has its bearings on a 'framework attached to the axle beneath the seed-box. On the shaft at proper intervals, is provided a series of screw-cylindery seed-distributers, revolving with the shaft. The screw of thecylinder may be'double or single, and of any practical form known,v to the nrt, or ofthe particular form represented in -the drawings; In thelatter form, the space between threads at one end of the cylinder is of a minimum size, both as to width and depth, andgradually increases in size both as to width and depth, until the. thread or threads worm the whole length of the cylinder;` The ends Vof lthe threads are lrounded from the outer 'periphery of the cylinder to thejbott'oin of the space between threads.

Eachcylinder is provided with a cup, of a half cylindrical form, or it may be of any other form ii'nown to the art, wherein the seed-cylinders rotate. AThe diiference in size between the diameter of the cylinder and the inner periphery of the cup is suiiicient to obviate any possible chancey of crushing or bruising the seed when the cylinders are revolving. The discharge-end of'the cup may hc ofany convenient form known to the art, that will admita discharge of the grain, or may-,be as represented in the drawings, wherein the cupl is notched and the ends partially moulded in towards the radial centre, in'such a form relative to the dischargele'nd'of the screw-cylinder, that when'the cylinder is in motion, a continuous and uniform discharge of the grain will be -e'ectefL Over each cylinder are located adjustable seniieircular caps or cut-os, which, together with thev cups, encircle the cylinders. The caps are each secured to aparall'el frame, which in turn is held to service by slidcbearings secured to the bottom of the'seed-box. The parallel frame and the caps are made to slide, and are designed both to cutod entirely the'flow of grain, and are adjustable to regulate the quantity of grain sown' toda, given area. It will be noted that by reason ofthe gradual increase of the space between the screw-threads in tle cylinder, andas you adjust or increase the opening of thefcap or cut-off relative to the cylinder, in-pro# portion you increase the discharge of the grain as to quantity. It may be remarked further, that the scattering of grain is uniform over the area travelled, whetherthe tnachine be driven quickly or moderately.

Beneath the 'seed-distributing cylinders and cups is arranged aseries of tubes or seattcrers, of a semi-` elliptcal form (horizontally.) The lower half of the innerer adjustable partis primarily dat, but has a conical form, with a half-ellipticalshaped angc at the bottom, and aaring or hopper-shape-at thetop. The outer or stationary part, while it is of a semi-elliptical form (hcrizontally,) is largt atthe top, and thus, in conjunction with the part first described, forms a hopper. Iltis smallest in the centre, and of a medium size at the bottom, suiiicient in size, however, to leave ample space between the outer and-stationary part and the inner. or adjustaf ble part for the discharge and scattering of the grain.

The inner partis--piovided centrally with slotted openings, that allow of avertical adjustment, and thus provides for an adjustment of the discharge that adapts the tubes to scatter equally well, over the same area,

wheat and oats.

The cultivator-toothis pivoted atone end of the lag. Dropping diagonally from the lug is a metallic rod or brace, the outer end being bent to a circular form, to allow an adjustmentof-tle tooth. The circular pai-t of the brace intersects the tooth to which the same is secu-rediy a hook-bolt; the hook clasping the brace,

' holding it firmly to the tooth, and is thus secured by a nut on the opposite side ofthe tooth. By loosening the 'nutand slid-ing the tooth, it may be adjusted to any required angle,

What Iclaim asmy invention, and desire to secure by Letters Patent, is 1. The screwcylinder d, cup m, and adjustable cap c, arranged relatively onev to the' other for joint action, lsubstantially as and for the purposes set forth. l

' 21 The screw-cylinder d in combination with cup m, as herein described for the purposes set forth.

3. The semi-elliptical tube or scatterer k Z, as and for the'purposes set forth.v 4. The'slots n n, as a means ofadjusting the part 'Zirelative' to the part k, as and for the purposes set forth.
