'A CORPORATION OF NEW YORK conmmaa HEAD Application filed February 23, 1926. Serial No. 90,137.

This inventiomrelatesto a new and improved container head.

An object of the inventionis to provide an improved container head for containers 50f the general type shown in United States Patent No. 1,414,861, issued May 2nd, 1922, entitled Container, in the name of Herbert L. Carpenter. Another objectis to provide a simple, efli-. .10 ient, strong, durable head made of composition material which will provide an effective substitute for a solid wood head or for an all-metal head.

A further object is to provide a head construction as a substitute for wood which will have a rigiditynot possessed by sheet steel or fibre alone. a The invention is illustrated. in the drawings, of which Figure 1 is a perspective view of one end of a container with our head in place.

Figure 2 is a partial vertical section through a container with the head in place. Figures 3to 8 inclusive illustrate the various parts ofthe combination of a container and head and rim separated.

Figures 9 to 13 inclusive illustrate modified forms of heads, all embodying the general principles of our invention.

'- The form of the invention shown in the.

drawings is a preferred form, although it is understood that modifications in the construction and arrangement of the parts and in the character of the materials used may 3; be adopted without departing from the spirit (0 being made of a combination of fibre, plaster or other material which can be molded, cast or compressed into .the desired form'and reinforoed on one or more faces with sheet fibre, fabric, metal or veneer.-

l B In view of the fact that there is an increa's ing demand :t'orsolid heads as a substitute for wood which will have" the rigidity not possessed by sheet steel or fibre alone, the evelopment of such ahead is of extreme im- At the present time container heads are -made up largely under three classes: (1) the regular stamped steel head in various forms; (2) the solid wood head in various forms; and (3) the compressed fibre head which is either rolled in sheets and then cut to the the proper shape, it would be of much more practical utility. Furthermore, if a hollow steel head were used and filled in with a composition, an eflective substitute would be produced. Furthermore, if the head is made on one .side with a lining of steel and on the other side faced with a strong fiber sheet it willmake a commercial substitute for wood which has a greatly improved strength, lightness and nail-receiving quality which are a distinct advance in the art.

Our inventions may take any one of the following general forms:

1. A reinforced, flanged head made of any suitable composition which can be cast or molded or compressed out of any desired material and reinforced with steel on the top face and fiber on the bottom face, or vice versa, or with both steel or both' fiber coveringson top and bottom. I

2. A reinforced, flanged head with a, thin fiber or steel flange and the filler or composition material only in the head proper.

When we talk of composition material we mean any material such as plaster, gypsum, wood pulp, cement, fibre or any other material which can be cast, molded or pressed into the desired shape, and when this .word

isused we intend to cover any such suitable substance.

In the lpreferred form of the invention shown in x e drawin the head is applicable to fill the opening ormed in the head of a container 10. A seal 11 of the form shown in Figure 7 is used. This seal is. of the type shown and descl lbed and claimed in the above mentioned United States Patent No. 1,414,861.

fibre 12 shownin Figure 6, a similarly shaped body portion of composition 13 shown in Figure and a cover portion of thin steel 14 compact head. The lower end of the flange 15 of the steel cover portion is bent as top'iedge of the container.

shown in Figure 2 to lie beneath the flange portion 16 "of the under layer or fibre 12. The cover in this form is preferably held on to the container by means of a flanged ring of steel 17 which acts as a rim and through thelateral flange of which nails 18 are driven into the head as shown in Figure 2. The container head shown in this form therefore comprises a body portion of composition cast, molded or pressed out of any suitable material, provided on one face with a thin layer of steel. and on the other face with a thin layer of fibre. In the particular form shown the steel reinforcing layer is on top of the composition body portion and the fibre reinforcing layer is on the bottom. It is within the scope of the invention to reverse the relative positions of these two reinforcing layers.

In the .form of the invention shown in Figure 9, which is a modified form, the body portion 19. is formed as before with a top reinforcing, layer 20, preferably of steel and a lower reinforcing layer 21, also of steel, but

in this case the lower layer extends up beyond the edge of the flange 22 on the body portion and is. bent inwardly in the formof a tang 23,

to lock with the composition of which the body portion is formed. It is to be under stood throughout the entire specification that wherever we talk of reinforcing-layers of I fibre or steel, that these layers can be interchanged for each other.

' In Figure 10 the body portion 24 made of composition has no flange which lies over the top edge of the container. In this case the flange for the head is formed by extending the top and bottom reinforcing layers and folding the outside edge of the top layer 25 around and under the flange periphery of the bottom layer 26.

In the form shown in Figure 11 the inner wall of the container 10 near the top is provided with a shoulder 27 and on this the head rests. In this case the head 28 of composition is covered entirely by a layer of fibre or steel 29, both on the top and the bottom and the head has no flange which extends over the case rests on the shoulder;

In the form shown in Figure 12 the body portion 30 of composition, is provided with the usual reinforcing layer 31 on its lower face which is provided with a flange 32 extending over the top edge of the container. .The top reinforcing layer 33 is preferably made'of pressed steel and continues in the form of a horizontal flange 34 over the top The head in thisedge of the container, and then down along y the outside of the container in an annular dependent vertical flan e 35. In this form of the head it is provide integrally with a rim' to enga e the container. This rim is formed by the anges 34 and 35.

In the form shown in Figure 13 we provide a body portion 36 of composition and in this case the lower reinforcin layer 37 is .made of pressed steel exten 'ng upward along the side of the inner wall of the container, then across the top in the form of the horizontal flange 38 and then downward along the outside of the container in the form of the vertical flange 39. In this case the top reinforcing layer 40 is preferably of fibre and is held in place by an inwardly protruding rib 41 formed out of the pressed steel layer shown in Figure 13.

It is obvious froma consideration of these.-

with a composition head a plurality of reinforcing layers on the top and bottom thereof of fibre or steel or any combination thereof.

' The device is extremely simple, can be manufactured economically and is a highly efiicient substitute for either wood or steel alone, having much superior qualities with respect to those elements in respect to lightness, strength and nail-receiving qualities.

What we claim is:

1. A container head comprising acomplete unit made of loose material stuck or bound together under suitable pressure, and a covering of sheet material enclosing all surfaces of said combined material and secured thereto, said covering being strong and relatively non-stretchable.

2. A container head comprising apomplete unit and consisting of a body port1on made in the form of loose pieces. of material stuck or bound together under suitable pressure, said body, portion having firmly secured thereto a layer of sheet material of such strength that tensional stress in the layer reinforces the body portion when sub ected to strains.

3. A container head as set forth in 01mm 1, and the edgesof one layer of the cover folded over and under the edges of the other la er.
