IMPROVEMENT IN GRAIN-Deuts.-

TO ALL WHOM IT MAY CONCERN:
Be it known that I, JACOB H. SHILEINER, of Camp Hill, Cumberland county, Pennsylvania, have invented a new and useful Improvement-in Grain-Drills; and I hereby certify the following to be a full, clear,\and
exact description of the same, reerencebeing had to the annexed drawings, making a part of this specification,
and to the letters of reference marked thereon.
The nature et' my invention consists -in combining a peculiarly-constructed device for scattering or distributing the seed or grain, with the boot, orconveyer-pipe, substantially as hereinafter set forth. A In the drawings- I Figure 1 is a vertical section of the lower end of the boot, or seed-conveying pipe, showing the improved device in proper position. y
Figure 2 is a transverse section of said boot, immediately above the device. vFigure 3 is a view in perspective of a part of the improved scatterer, or distributor, styled the contractor. In figs. 1 and 2, A. represents the boot or conveying-pipe. This is made of a proper length and size, and is given the form or contour substantially as shown in the transverse section in lig. 2. -At a proper distance from its lower end, upon the inside of said boot A, thc'contractor B is placed. Said contractor is made in the form of an inverted frustum of a cone; it is hollow, and open at both ends; its upper end is made of such relative size to the inside of the boot, as to neatlyt it, a shoulder of proper shape being formed upon the inner surface of the boot to accommodate it, as seen in iig. 1. The said contractor Bean either be cast of the same material and in position in the boot, or be made-separately, and attached by any suitable method. In
fig. 1 it is shown as being made separate, and held in place by pins or rivets.
Upon the inner surface .of the contractor B, a cross-bar, a, is placed, or rigidly fastened, as seen in fig. 1. This bar is so constructed that its upper side shall form anedge, so as to prevent grain or seed from lodging or being impeded in its passage. v p i The cross-bar a is furnished with a boss, or rounded-enlargement, at .its centre, midway between `the walls of the contractor B. Said boss has a hole made through it, of a proper size to receive the bolt or stud c that projects from the apex or crowniof the bell-shaped seed-scatterer C. Said scatterer C is given the form, subv stantially as shown in iig. 1, and,as before stated, has a bolt or stud, c, projecting from its upper'end, that passes through the hole formed for its reception in cross-bar a. .It is secured in said position by a nut, e. At
the rear of the contractorB,lf1-om its lower end, a piece, b, of` peculiar form, shown ,in figs. 1 and 3, projects downward, and bears against the side of the bel shaped distributor C. Said piece 6 is intended to deflect or throwV forward thegrain or seed that'falls on the rear of the scatterer G,`as such grain, if this provision were not made, would be liable to be improperly covered. The piece Z also serves as a support or brace to the seattcrer C.
The boot and'also the distributor and contractor are made of cast iron, or other suitable material.
Figure 3 shows a front view of thc contractor B, and also'of the brace or deector b.
'The several parts of the device being placed together in proper position, as shown in iig. 1, the operation is as' follows: y
,2, The grain being fed into the boot A by the mechanism usually employed in grain-drills, falls down said boot, and is. gathered or conccntratcd,'by the contractor B, toward the centre of the boot, so that it falls directly upon thc crown and'sides of the bell-shaped' distributor C, and is by it evenly distributed over the surface of the ground immediately under it, the guard or brace b preventing it from flying in the rear too far,
and thus be left uncovered. The grain after it is' sown is covered by any suitable attachment that will pperly effect the purpose.
I am awarethat grain-scattering or spreading devices have already been patented, and are in use. But they are defective, from the fact that in using-the machine upon a hill-side, the grain, in the operation of sowing it, falls almost entirely upon the lower side of the scatterer or spreader, and is of course imperfectly distributed.
vThis effect I entirely overcome by the peculiar action of the contractor-B, in combination with the bell-shaped scatteer C, as'the grain will always be concentrated upon the crown of the scatterer C, no matter what degree of inclination the feedpipc or boot A assumes, and will, therefore, be as evenly and perfectly sown upon the side of a. hill as upon level ground.
I do not d esire bioadly to claim the general use of a scattering-device, conical or other shaped, when used alone; but
What I do claim as new, of my invention, and desire to secure by Letters Patent of the United States, s-
The combination and arrangement of' the boot A, with the contractor B and distributor C, when said distributei is sustained in position, substantially as shown and described.
