Machine for the pneumatic spreading of granular material
First Claim
1. In a machine suitable for broadcasting of granular material while traveling over an area in which the material is to be distributed, comprising(a) a central reservoir for holding a supply of the material,(b) two side booms for disposition in the working position transversely of the direction of travel with one boom on each side of the reservoir, each boom including an inner boom member and an outer boom member, the inwardly disposed end of each of the inner boom members being interconnected with the reservoir by spaced bearings for pivoting about an axis extending in the direction of travel for swinging of the inner boom members to a generally upright transport position,(c) a plurality of conduits connected to the reservoir for receiving material therefrom and mounted on the side boom for delivery of the material to spaced discharge points disposed along the booms,the improvement which comprises:
- (d) each outer boom member being pivotally mounted on its inner boom member on an axis disposed vertically with the side booms in the working position for folding of the outer boom member into a position aligned with the inner boom member in the direction of travel, for the transport position.

Abstract
A machine for broadcasting material over the ground having booms (15) which carry flexible distributing conduits (10), and extend laterally outwardly from the centrally disposed hopper (2) for broadcasting of the material, and are folded up, about horizontal pivot axes (19), against the hopper for transport of the machine over e.g., roads. Each boom includes an inner boom member (17) and an outer boom member (18) which are pivotally connected at an axis (22) so that the outer boom member can be folded into alignment with the inner boom member in the direction of travel (16). By this construction the width required for the booms when in the transport condition is reduced.
