Machine for distributing material
First Claim
1. Machine for distributing granular or powdered material and suitable for being pulled by a tractor, comprising a frame, a hopper mounted on the frame, furrow openers mounted on the frame, material conveying tubes connected to the furrow openers and the hopper for the transport of material from the hopper to the furrow openers, the furrow openers having outlet orifices for delivery of said material to the soil, furrow closers connected to the furrow openers for pivoting in vertically extending planes with respect to and behind the furrow openers, each furrow closer comprising a support pivotally connected to the furrow opener and a hiller mounted on the support by a mounting device for projection of the hiller below the mounting device and into the soil for closing of a furrow, the hiller being secured to the mounting device by a releasable fastener so that the length of the projection of the hiller below the mounting device can be adjusted, the furrow openers being movable between a lower position and an upper position with resultant movement of the furrow closers to, respectively, penetrate the ground and raise from the ground, the pivot mounting of the furrow closers and the length of the supports, and the adjustability of the adjustable mounting of the hillers on the mounting devices being such that the hillers can be disposed on the supports so that in the raised position the hillers are disposed beneath the furrow openers so that when the furrow openers and furrow closers are lowered, the hillers contact the ground and support the furrow openers above the ground so that the outlet orifices do not become plugged with soil, and while in the working position the hillers are the only parts of the furrow doses which contact the ground the hiller being formed of a single piece of flexible spring steel strip and consisting essentially of two downwardly projecting fingers, a U-shaped section, and sections joining the free ends of the U-shaped section to the upper ends of the fingers, said U-shaped section being arched to provide the U-shaped section concave when viewed from the forward end of the machine, the hiller being clamped on the mounting device at the arched portion.

Abstract
Machine for seeding designed to be pulled by a tractor and outfitted with seed drills for depositing of the seeds in the soil. A furrow opener is mounted forward of the seed drill, and a furrow closer is mounted aft of the seed drill. The furrow closer is mounted on the frame for pivoting in a vertically extending plane behind the seed drill, and comprises a support pivotally mounted on the frame and a hiller mounted on the support by a mounting device for projection of the hiller below the mounting device and into the soil for closing of the furrow. The mounting device is secured to the support by a releasable fastener so that length of the projection of the hiller below the mounting device can be adjusted.
