MACHINES FOR SPREADING ARTIFICIAL FERTILIZERS AND THE LIKE Filed Sept. 1, 1953 2 Sheets-Sheet 2 United States P MACHINES FOR SPREADING ARTIFICIAL FERTILIZERS AND LIKE Herbert Vissers, Nieuw Vennep, Netherlands, assignor to C. V. Machinefabriek H. Vissers, Nieuw Vennep, Netherlands, a Dutch company Application September 1, 1953, Serial No. 377,906

Claims priority, application Netherlands September 11, 1952 1 Claim, (Cl. 222-177) This invention relates to a machine for spreading artificial fertilizers and the like, provided with a number of pans or discs, each located beneath a discharge orifice of a hopper and having a toothed rim meshing with a worm secured on a drive shaft extending across the machine below the hopper, the end walls of the hopper each being united directly or indirectly with the journal of a road wheel and the hopper having its bottom on a lower level than the journals of the road wheels.

The invention has for its object to improve a machine of this kind in such a manner that it may easily be assembled and dismantled in order to be dispatched in parts. According to the invention each end wall of the hopper is formed as a support member and said support members being clamped on the ends of a bar extending in transverse direction below the hopper, a bracket for each pan being clamped on said bar. Said construction not only presents the advantage that it can easily be assembled and dismantled, but also the brackets for the pans and the support members, forming the end Walls of the hopper, may be used for machines of different width. The arrangement of a bar extending below the hopper and uniting the support members of the wheel journals results in a rigid construction and as the bottom and the longitudinal walls of the hopper are not positively connected to said support members the hopper is relieved from forces.

being driven by the' road wheel 7 through the intermediary of a gear 14.

The bottom of the hopper consists of plates which at one of their sides are loosely supported on the angle shaped bar 10 and at its other side are supported on a lug 16 secured at the under side of the bar 8 of T-section. The end walls 17 of the hopper are formed by the support members 4 and the longitudinal walls 18 of the hopper are loosely supported on the bars 8 and 10 respectively and against the flanged edges of the end walls 17. At each end of the longitudinal walls 18 of the hopper a projection 27 is provided which cooperates with alocking arm 28 rotatably secured to the end wall is secured to each lever.

17 and adapted to press on the projections 27 for retaining the walls 18 in their position.

The T-shaped bar 8 at each pan 2 is provided with a projecting arm 19 for supporting a shaft 20 carrying blades 21 above each pan for spreading the fertilizer. To the T-shaped bar 8 further a scraper 22 and a guide 23 for each pan is secured. The shaft 20 is driven from one of the road wheels.

Further a shaft 24 is journalled in the arms 19 and said shaft carries a lever 25 for each pan and a valve for controlling the discharge of the material to be spread On the bar 1 two brackets 26 are clamped for securing the draw means.

What I claim is:

A machine for spreading artificial fertilizers and the like having a plurality of pans, and a hopper having a plurality of discharge orifices and comprising two oppo'sitely disposed end walls, a bottom and longitudinal Walls, each of the said pans being located beneath the corresponding discharge orifice of the said hopper and having a toothed rim, a drive shaft extending across the machine below the said hopper and carrying a plurality of worms, each of the said worms meshing with the toothed rim of its corresponding pan, at least two road wheels and each of the latter having a journal, each of the end walls of the said hopper being united with the journal of the corresponding road wheel, and the said hopper having its bottom on a lower level than that of the journals of the said road wheels, a bar extend- The invention will be further described with'reference to the accompanying drawing, Fig. l of which shows part of a plan view of an embodiment of the machineaccording to the invention.

Fig. 2 is a vertical cross section taken on line IIII of Fig. 1. v 7 On a tubular bar 1 a bracket 3 is secured for each pan or disc 2. A support member 4' is clamped on each end of the bar 1 by means of a bolt 5. Said support member carries a journal 6 for the road wheel 7 and connected to each support member is the end of a bar 8 of T-section by means of a bolt 9 and said bar extends through the Whole width ofv the machine. Connected to each support member 4 is further the end of a bar 10 of angle-shaped section also extending through the whole width of the machine.

Each pan 2 has at its under side a toothing 11 which meshes with a worm 12 arranged on a shaft 13 supported in part of the brackets 3 carrying the pans, said shaft ing across the machine below the said hopper, each of the end walls of the said hopper being constituted by a support member clamped on the ends of the said bar and being provided with flanged edges, supporting bars extending at the bottom of said hopper between said end Walls, the said longitudinal walls and the bottom of said hopper being free from the said end walls thereof and supported by said supporting bars, and the said longitudinal walls being further supported'by said flanged edges of said end walls, a bracket for each pan, and draft means for the said machine being clamped on said bar.
