IMPROVEMENT IN THE SEEDING-ROLLER OF SEED-PLANTER.

Specification forming part of Letters Patent No. 7,642, dated September l0, 1850.

YTo all whom it may concern Be it known that I, AARON PALMER, of Brockport, in the county of Monroe and State of New York, have invented a new and Improved Seeding-Wheel for Planting-Machines; and I do hereby declare the followingto be a full and exact description thereof, reference being had to the accompanying drawings, makinga part of this specification, in which- Figure 1 is a side elevation; Fig. 2, a sectional view in the direction indicated by the red lines in Figs. 3 and @and Figs. 3 and 4 are perspective views ot' the two principal component parts of the seeding-wheel detached.

Similar letters indicate like parts in all the ligures.

My improved seeding-wheel for plantingmachines is constructed by the union ot' the two parts which are represented in Figs. 3 and 4.

d is a disk with a hole '1n its center,an d having a series ot' segmental tlanges,e, rising from its periphery, between which iianges are the openingsff, at one extremity of each of the iianges e e. They turn inward toward the center of the disk, as shown at g g, Fig. 3.

tt is a disk, having the iiange b projecting from its outer side, the lugs c c radiating from its periphery, and the tube t' projecting from its center. The disk a is received within the segmental iianges e e rising from the disk d, and the tube t' passes through the hole in the center of d, as shown in Fig. 2. The depth of the disk a corresponds with the height ot the flanges eg, and the lugs c c, radiating from the periphery of a, extend outward to the iuner surfaces of the flanges e e. rlhe ange b, radiating from the outer side of a, bears upon the extremities ot' the segmental flanges e e, rising from d, and its periphery corresponds with the periphery of the said segmental When the parts a and d are thus placed together they are secured by the nuth, which works upon the screw cut upon the tube t'.

rlhe seeding-wheel thus constructed is placed upon the shaft of a planting-machine, within the grain or seed receptacle, in any usual or Well-known manner, the shaft passing through the tube i.

ff are openings to the planting-receptacles in the periphery of the seeding-wheel, the boundaries of which receptacles are formed by the inner surfaces of the segmental anges e e, the outer periphery of a, the lugs c c, and the radial portions g g of the segmental flanges; or, when very shallow planting-receptacles are required, they are bounded by the sides ot' the openingsff and by the extremities of the lugs c c. It will therefore be perceived that by loosening the nut It and turning the part a within the inclosing part d, so as to bring the lugs c c under the openingsff, or by turning the part a in an opposite direction,so that the Wings c c will be carried toward the rear sides of g g, the planting-recesses can be made small and shallow enough for the smallest description of seeds or large and deep enough for any kinds ot' grain, or for depositing a larger or a smaller quantity of' seeds at a time.

What I claim as myinvention,and desire to secure by Letters Patent, is-

The constructing a seeding wheel for a planting-machine by the combination ot' the two parts a and d, ot' the form herein described, in such a manner that by turning one of the said parts within or upon the other in one direction the planting-receptacles will be reduced in depth and size, and by turning the said part of the seeding-wheel in an opposite direction the planting-receptacles will be enlarged in depth and size,substantially as here in set forth.
