8 Claims.

My invention relates to Spreaders, and more particularly to a type of spreader adapted for usein the loading of grain or the like in the hold of a ship.

An important object of my invention is to provide a spreader that will distribute the material part of this specification, and in which like nu- V merals are employed to designate like parts throughout the same,

Figure 1 is a top plan view of a device embodying my invention.

Figure 2 is a vertical section taken on the line 22 of Figure 1,

Figure 3 is a transverse sectional View taken on the line 3-.-3 of Figure 2, and

Figure 4 is a transverse sectional view taken on the line 4-4 of Figure 2.

In the drawings, wherein for the purpose of iilustration is shown a preferred embodiment of my invention. the numeral it! designates the deck of a ship and removably positioned in the open hatchway thereof is a substantially square frame H formed with an annular flange l2 adapted to rest on the upper surface of the deck around the said hatchway and to hold the frame securely in place. Extending upwardly from the frame 5 I is a superstructure comprising upright members 13 at each of the four corners, and upright members It riveted or otherwise secured to the frame intermediate its corners. A circumfere-ntially extending frame i5 is secured to the upper ends of the upright members i3 and M. The superstructure is provided with a horizontally disposed top It formed with a centrally positioned an nular flange I! over which is fitted a cover i8 having a substantially key-shaped opening it in its top. Extending inwardly from the middle uprights It are right angularly disposed supporting members 2%] joined at their point of intersection to form a bore 2! in which is mounted a shaft 22, the upper end 23 of which extends upwardly through the smaller portion of the key-shaped opening 19 in the cover i8 and carries thereon a clevis member 2 5. The upper portion 23 of the shaft is screw threaded to receive a bolt 25 which bears against the supporting members 2% to immovably position the shaft 22 within the bore 2|.

The lower end of the shaft 22 terminates within the hold of the ship and carries thereon a stationary circular spreading disk 26. Disposed above the disk 26 and spaced slightly therefrom is a rotatable spreading member 21 which is of substantially square formation in plan, and its diagonal width is slightly less than the diameter of the said disk. The spreading member 2'! is provided at each of its four corners with arcuated wings 28 which extend outwardly therefrom. and align with the periphery of the disk 25, and with substantially V-shaped recesses 30 on its upper surface extending from each corner thereof to the middle of each side. Extending vertically from the spreading member 21 and rotatable therewith is a sleeve member 29 which receives the shaft 22 therein and terminates a substantial distance from the supporting members 26. The upper surface of the spreading member 21 is also provided with arcuated fins 3! which extend from the sleeve 29 to each of the corners of the member 21 and curve rearwardly and upwardly therefrom to form a continuation of the V-shaped re cesses 30. Interposed between the upper end of the sleeve 29 and the supporting members 20 is a motor 32 adapted to engage the sleeve 29 and to rotate the said spreading member 2?. While I have here illustrated the rotating means as an electric motor, it is to be understood that I do not wish to be restricted to the same, and that 3! and slides into the V-shaped recesses 30 which A then drops the material onto the stationary spreading platform 26 in a manner to permit the vertically disposed sides of the spreading member 2'! to deflect the same into the path of the arouated wings 28, the rapid rotation of which wiil exert sufficient centrifugal force on the grain particles to distribute them evenly and efficiently Within the hold of the ship. It will be seen that due to the rapid rotation of the spreading member 21, my device is capable of disposing of great 5 quantities of grain, or other like material, within a comparatively short time and that due to the unique construction of the same the particles thereof will be spread evenly and efficiently with in the hold of the ship. The clevis member 24 secured to the upper end 23 of the shaft 22 provides a means whereby a rope or the like may be attached, and the spreader in its entirety removed or positioned in the hatchway of the ship.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of my invention, or the scope of the appended claims.

Having thus described my invention, I claim:

1. A grain loader comprising a frame adapted to engage with the hatchway of a ship; a superstructure forming a part of the frame and extending upwardly therefrom; a shaft immovably carried by the superstructure and depending therefrom into the hold of the ship; a stationary spreading platform secured to the depending end of the shaft; a spreader member rotatably mounted on the shaft, above and spaced from the said spreading platform, comprising a substantially square body portion having arcuated wings at its corners thereof, V-shaped recesses extending from each corner to the middle of each side, and arcuated fins diagonally mounted on the upper surface thereof to direct the grain into the said V-shaped recesses; and means to rotate the said spreader member.

2. In a grain loader, as a sub-combination, a vertically disposed shaft, a stationary platform carried by the shaft, a rotatable spreader mounted on said shaft above and in slight spaced relation with the platform, said spreader comprising a block-like body member having angularly related vertical sides and substantially V-shaped recesses in its upper surface, and dispersing fins projecting laterally from the said sides, the said recesses delivering the grain to the platform and into the path of the vertical sides which sweep the upper surface of the platform to deflect the grain into the dispersing fins.

3. In a grain loader, as a sub-combination, a shaft, a stationary platform carried by the shaft, a rotatable spreader member mounted on said shaft above and in slight spaced relation with the platform, said spreader member comprising a shape having a plurality of circumferential angularly related side walls, and with synclinal formations in the top thereof radiating from the center to the middle of each of the sides, and dispersing fins projecting laterally from the spreader member at the intersections of the said sides the said synclinal formations delivering the grain evenly onto the platform and into the path of the side walls which sweep the upper surface of the platform to initially agitate the grain thereon and to deflect the grain into the said dispersing fins.

4. A grain spreader comprising, as a sub-combination, a stationary support, and a spreader member mounted for rotation relative to said support, said spreader member comprising a substantially square body portion having vertical side walls and lateral fins at its corners thereof, V-shaped recesses in its top radiating from the center and extending from each corner to the middle of each side, and synclastic arcuate fins mounted in the upper surface of the body portion to direct the grain into the V-shaped recesses and onto the said support, the side walls sweeping the said support to initially agitate the grain directed onto the support and to deflect the same into the said lateral fins.
