JAMES a TEAGUE ATTORNEY Aug. 4, 1964 J. D. TEAGUE BULK PRODUCT LOADER Filed Jan. 22, 1962 2 Sheets-Sheet 2 BY L23 J \H I W ATTORNE Y United States Patent 3,143,372 BULK PRODUCT LOADER James D. Teague, 3361 Oak Knoll Drive, Los Alamitos, Calif. Filed Jan. 22, 1962, Ser. No. 167,738 2 Claims. (Cl. 294-41) This invention relates to a bulk product loader whereby granular material may be loaded into a container and transported in that same container to its final destination, and then unloaded from the container at the place of use.

An object of my invention is to provide a novel bulk loader into which granular material may be loaded and kept dry and safe from contamination while the material is being transported from place to place by means of ship, train, truck, or the like.

Another object of my invention is to provide a novel bulk loader which is provided with releaseable doors at the bottom which can be opened to permit the granular material to flow from the load by gravity.

Another object of my invention is to provide a novel bulk loader which is provided with a novel latching means for the doors which can be easily released, either manually or mechanically as might be required.

Still another object of my invention is to provide a novel bulk loader in which the granular material can be loaded through appropriate access holes through the top wall or roof of the loader.

Still another object is to provide a means of lifting and moving the bulk loader from place to place in order to position the loader in the hold of a ship, or in a railway car, truck, or the like.

Other objects, advantages and features of invention may appear from the accompanying drawings, the subjoined detailed description and the appended claims.

In the drawings:

FIGURE 1 is a perspective of my bulk loader.

FIGURE 2 is a top plan view of the same.

FIGURE 3 is a side elevation of the same as viewed from the right-hand side of FIGURE 1.

FIGURE 4 is a side elevation of the same as viewed from the left-hand side of FIGURE 1.

FIGURE 5 is a sectional view taken on line 55 of FIGURE 3.

FIGURE 6 is an enlarged fragmentary sectional view of the area numbered 6 in FIGURE 5.

FIGURE 7 is a view similar to FIGURE 6 but showing the door in open position.

FIGURE 8 is an enlarged fragmentary sectional view of the area indicated at 8 in FIGURE 5.

FIGURE 9 is a fragmentary sectional view taken on line 99 of FIGURE 1.

FIGURE 10 is a sectional view taken on line 1010 of FIGURE 4.

FIGURE 11 is an enlarged fragmentary sectional view of the area indicated at 11 in FIGURE 10.

Referring more particularly to the drawing, my bulk product loader consists of a plurality of side walls 15, which are preferably formed of a suitable metal and are welded or otherwise attached at their abutting edges to form a complete rectangular inclosure. A roof or wall 16 incloses the top of the loader and the roof is slightly domed or curved upwardly for the purpose of drainage. A plurality of access holes 17 are provided in the roof 16 to permit granular material to be poured into the loader to fill the same. Appropriate covers 18 inclose the manholes 17 to seal ofi these access holes during transportation.

In order to lift and move the loader from place to place I may provide transversely extending

angle members

19 and 20, one on each side of the roof 16, and these angles are engaged by a suitable lifting jig 21, the angles of which ice engage the

angles

19 and 20 so that the entire load can be lifted from a boom and carried to an appropriate position in the ship, car, or the like.

To inclose the bottom of the loader I provide two

doors

22 and 23. These doors are both hingedly secured at one edge to one of the walls 15, by hinges 22' and 23 respectively so that they can be swung into open or closed position during unloading and loading of the bulk product within the loader. The door 23 is somewhat shorter than the door 22 and for this reason this shorter door will close first in order that the inner abutting edges of the two doors may partly overlap when closed. The inner edges of the

doors

22 and 23 are tapered, as shown at 24, to provide an overlapping edge, and these overlapping edges are sealed by a flexible sealing strip 25. The space between the

doors

22 and 23 and the bottom edges of the walls 15 may be sealed by a flexible strip 26 attached to the bottom edges of the walls 15, if this is necessary. At the hinged end of the doors 22 and 23 a flexible seal strip 27 may be provided, which is engaged by a solid weather strip 28 attached to the

doors

22 and 23.

In order to hold the

doors

22 and 23 in closed position, I provide a latch mechanism which consists of latch fingers 29, which are attached to each side of the door 22 and project upwardly a suitable distance to be engaged by a latch mechanism, to be subsequently described. The fingers 29 are a rigid part of the door 22 and move arcuately adjacent to a wall 15 of the loader.

A latch mechanism to engage the fingers 29 consists of two

horizontal bars

30 and 31, which extend horizontally and are pivotally mounted to the Walls 15 as follows: an

ear

32 and 33 is formed at each end of the

bars

30 and 31, and these ears are pivotally attached to the side walls 15, as best shown in FIGURE 1. A latch block 34, attached to the inside of the bar 30, is positioned between the finger 29 and a block 35 to hold the finger 29 securely in vertical position and thus hold the doors 2223 closed. A handle 36 extends between the ears 32-33 and this handle may be grasped by the workman to swing the bar 31 either inwardly or outwardly, to either engage the finger 29 and latch the doors 22-23 in closed position, or to release the finger 29 and permit the doors 2223 to open under the weight of the granular material within the bulk loader.

T o prevent the doors 22-23 from accidentally opening in transit, the fingers 29 may be locked in a position to hold the doors closed by means of a hook 37, which is pivotally attached to a side wall 15 of the bulk loader and which hooks over the finger 29, as shown in FIGURES 1 and 4, to hold that finger in vertical position and with the doors 2223 closed.

In Operation The

bulk loader doors

22 and 23 are closed and latched by swinging the doors inwardly until their meeting edges overlap, and with the finger 29 in vertical position. The latch bar 30 is now swung inwardly so that the block 34 engages one edge of the finger 29, thus holding the doors 22-23 closed. At this time the hook 37 may also be swung over the finger 29 to further insure that the doors 2223 will remain closed. The access hole covers 18 are now removed and the entire bin is filled with the desired dry granular bulk material. When the bin is full the access hole covers 18 are replaced and the entire bin or bulk loader can be moved into the hold of a ship or in a car, as might be required. The bins are thus moved from place to place with their granular contents, and these bins are so sturdy and the various joints thereof are so sealed by appropriate packing that the contents will remain dry and uncontaminated.

Having described my invention, I claim: 1. A bulk product loader comprising a bin having side Walls and a top, a pair of bottom doors hingedly mounted on two opposite side walls, the inner edges of said doors overlapping, a finger extending vertically from that one which extends beyond the other, and a latch bar hinged on the side walls of the bin and having a block located thereon to engage behind the finger to prevent swinging thereof and release of the bottom doors, and an additional locking means for the finger in the form of a hook pivoted on a side Wall and eng'ageable about the upper end of the finger.

2. A bulk product loader comprising a bin having side walls and a top, a pair of bottom doors hingedly mounted on two opposite side Walls, the inner edges of said doors overlapping, a finger extending vertically from that one which extends beyond the other, and a latch bar hinged 1;,

on the side Walls of the bin and having a block located thereon to engage behind the finger to prevent swinging thereof and release of the bottom doors, and an additional locking means for the finger in the form of a hook pivoted on a side wall and engageable about the upper end of the finger, said top having an access hole therein.
