UNITED STATES JOHN H. P ROCTOR, 0F ANDOVER, MASSACHUSETTS, ASSIGNOE TO GARDNER W. PEAR- SON, OF LOWELL, MASSACHUSETTS.

WOODEN CONTAINER.

Application filed November 28,1923. Serial No. 677,401.

, This invention relates to shipping containers, particularly of the classin which liquids are shipped. It is especially valu-" able for explosives where it is desirable that there should be no metal ofany kind,'butit is also of such. character that it is liquidtight and cannot split or leak even when it is not filled for a considerable time.

Broadly speaking, my preferred form comprises a cylindrical wall of cross-grained or cross-banded plywood with heads formed of crossegrained or cross-banded plywood moulded or shaped so that the edge or rim is bent at right angles to the body, each head being then forced into position inside the wall.

In the drawings, Figure 1 is a sectional elevation of a container of my preferred construction.

1 Fig.2 is a perspective showing one way f building up the veneer before it is rolled to form the cylindrical wall.

{Fig 3 is a perspective view showing anuil ing up the veneer before it is rolled to form the cylindrical wall.

, Fig. at is a perspective view showing a single sheet of veneer before it is rolled,

the grain being positioned so that it will run lengthwise of the finished wall. a

Fig. 5 is a plan View, parts being broken .away, showing layers of veneer as they are put together before being pressed into shape to form a head. In this figure the difference in the diameters of the layers of veneer forming a head are exaggerated.

Fig. 6 is a sectional elevation showing a head as it is formed in a suitable press.

Fig, 7 isa sectional elevation of a barrel with a bulging cylindrical wall having a head of my construction.

' In the drawings, A represents a cylindrical wall formed of a plurality of sheets of wood veneer such as 10, 11, 12, 13, 14, some grain running at different angles from others and with waterproof glue between the sheets. These are preferably rolled together under pressure sufficient to force the glue to penetrate the pores and crevices in the wood, the cylinder being then held in position until the glue firmly sets.

Such a cylinder can be rolled in a manner similar to that shown in my prior Patent N 0. 1,443,196, January 23, 1923, where sheets of veneer 10, 11, 12, 13 and 14 are connected together by tape 15, some having the grain running at different angles from others as see F g. 2, and rolled up on a suitable mandrel in the manner there described, with waterproof glue between the layers.

As shown in Fig. 3, sheets of veneer having the grain running at different angles,

one direction, rolled up on itself as shown at 17, but this construction is not as strong as the cross-banded or 'cross-grainedarrangement shown in Figs. 2 and 3.

The heads are formed by cutting discs of veneer such as 30, 32, 34 and 36, and in the rim of each cutting radial gores ,31, 33, 35, 37 arranged in staggered relation and applying waterproof glue between the discs, then placing the whole on a suitable mould H, as shown in Fig. 6, and then by means of a die K attached to a plunger L upsetting the Wood at the rim and forcing it into the dish=shaped female member 40 between it and the male member 41, and holding it under pressure until the waterproof glue penetrates the pores and crevices in the wood and sets.

The diameter of the inner disc 30 which is to form the inside of the disc-shaped.

head B is the smallest and the diameter of the other .discs is progressively larger to the outside 36 which is the largest. It is clearly shown in Figs. 1 and 6 that after passing through the dies, the outer rims or edges will even up so that no cutting is required, and the gores will take care of the excess of material so that there is little if any crushing of the grain of the wood, and the strength is not impaired.

After this is completed, one head or two heads B are forced inside the circular wall A, as shown in Fig. 1, and fastened in position by wooden pegs C or by glue alone as shown in the top head.

I may use my heads such as B in an ordinary barrel of stave construction with the usual bulging cylindrical wall as shown at M in Fig, 7 or in fact I can use my heads with any container having a wooden, metal or fibre cylindrical wall.

I claim:

1. In a shipping container, the combination of a cylindrical wall formed of a plurality of sheets of wood veneer some having their grain running at different angles from others with waterproof glue between the sheets and penetrating the pores and crevices in the wood; with heads formed of circular sheets of veneer of greater diameter than the inner diameter of the wall and having their grain running at different angles and their rims gored in staggered relation, with Waterproof glue between the sheets, the gored rims having been upset under pressure and the heads having been torced inside the circular wall; and wooden pegs driven through said wall and rims to hold the heads in position.

52. In a shipping container, the comhination of a cylindrical wall formed of plywood; with heads formed of circular sheets of veneer ot greater diameter than the inner diameter of the wall and having their grain running at different angles and their rims gored in staggered relation, with waterproof glue between the sheets, the gored rims hav ing been upset under pressure and the heads having been forced inside the circular wall; and means to hold the heads in position.

3. In a shipping container, the combination of a cylindrical wall formed of wood; with heads formed of circular sheets of veneer of greater diameter than the inner diameter of the wall and having their grain running at different angles and their rims gored in staggered relation with waterproof glue between the sheets, the gored rims having been upset under pressure and the heads having been forced inside the circular Wall; and means to'hold the heads in position.

6t. A head for wooden containers formed of circular sheets of veneer havin their grain running at dilterent angles, their rims gored in staggered relation with waterproof glue between the sheets, the gored rims having been upset under pressure.

5. A head for containers formed of circular sheets of veneer of progressively increasing diameters having their grain running at diilerent angles, and each having its rim gored, such gores being in staggered relation to each other and with glue hetween the sheets, the gored rims havingheen upset under pressure and the largest sheet being on the outside.
