Patented pr. 10, .1934

PATENT OFFICE UNITED STATES smooth surface on its inner and outer faces;`

which requires no hoops of wood or metal to bind it together; which is of great strength and yet is sufliciently resilient to resist breakage from.

rough handling; which is substantially as strong in the seams as at other points thereof; which is substantially as strong' as and ofi about one-half the weight of the. barrels commonly in use at the present time; which requires no special tools or devices for assembling, closing or sealing; and which will hold its contents securely and adequately protect themfrom damage.

I attain these and other objects by the devices and arrangements illustrated in the accompanying drawing; in which- Figs. 1 and 2 are enlarged-sections showing, respectively, two contiguousedges of two semi- 'cylindrical sections of a barrel, separated; Fig. 3 shows them secured together to vform the joint or seam of the barrel; Fig. 4 is an end` elevation of one such semicylindrical section before being assembled with a complementary section to form a barrel; Fig. 5 is an end view of a nest of such sections ready for storage or shipment; and Fig. 6 is a side elevation of my improved barrel, showing a part of its side broken away to reveal the means of closing the ends thereof. I

Similar numerals of reference refer `to similar parts throughout the several views.

Referring to the drawing, it will be seen that my improved barrel comprisestwo arcuate sections, 1 and 2, built up of the usual construction of plywood, in which the grain of the several layers runs at right-angles to that of the contiguous layers, and each having the inner side of one longitudinal edge -3 and the outer side 4 of the other longitudinal edge cut away to the center '.of the thickness of the plywood (Figs. 1 and 2), for a short distance from said edge, to permit a similar section to be fitted thereto (Fig. 3) to form the two longitudinal joints or seams (Fig. 6) ofV the barrel. As above stated the edges Y, are cut away in complementary manner to give p a wide arcuate or tangential joint between the said parts and to permit the adjacent edges and shoulders to butt against each other. It will be readily understood from a consideration of Fig. 3 that the strength of the barrel at the seam, thus formed, is substantially the same as at other portions thereof because, as is well understood, the grain of the central layer of plywood extends around the barrel while-the grain of the inner and outer layers extends parallel to the axis, Since the central layers of the two sections forming the joint are only partly cut through, it follows that the outer and inner layers are both re- (i5 enforced against splitting by the uncut portion of the central layers. The outer and inner layers of the barrel, therefore, provide the requisite axial strength and stiffness tothe barrel, while the inner layer provides the circumferential TG allel to the axis of the barrel.

Under usual conditions I prefer to secure the two edges of the sections together by means of staples 5, driven in from the outside and clenched on the inside, but nails, tacks, or other securinao means may be adopted if desired.

The ends of the barrel may be closed by solid wood or plywood closure pieces 6, cut to proper size and shape and secured in place by suitable cleats 7, fastened into .the inner edge of the barrel. These cleats 7 may be conveniently made from trimmings of the barrel sections 1 and 2 and may be extended entirely around the inner periphery of the barrel, outside of the head 6, or may be made of shorter pieces, spaced apart, as is desired for the particular use to which` the barrel is put. Thus it will be seen that my improved barrel maybe shipped and stored in nested or knockdown condition, as indicated in Fig. 5 and, when it 95- is desired to' use them, they be assembled by 4placing two such sections in reversed relative positions and stapling the edges together through the lap joint above described. Such a barrel will expose a smooth surface, both to the outside and the inside will occupy the least possible space; will add but little weight to the weight of the material being shipped therein; will be strong and stiff and yet resilient; and will stand a great amount of rough handling without injury.

Although, in the drawing and in the above description, AI have shown and described a barrel constructed of three-ply plywood, itis to be understood that I do not conne myself to any particular number of plies of which such plywood is to il be constructed but that there must be at least three such layers. In practice it may be found that ve or even more layers will be necessary for barrels designed for particular purposes, but for ordinary use it has been found that threeply construction is most satisfactory, It is, of course, to be understood that the several layers of the plywood are properly cemented or glued together in the usual manner. Also, I have shown and described the barrel as made in two semicylindrical sections 1 and 2, but itis to be understood that I do not wish to limit myself to any particular number of such sections as the barrel could be made in three or four sections without materially affecting its strength, but, again, I nd that the semicylindrical construction is most satisfactory. Again, if the knockdown feature of this construction should not be desirableythe barrel may be made in a single section having only one seam.

Having described my invention, what I claim 1. A joint between two bodies of wood, each body comprising two layers of wood cemented together to form a single structure, the rst or contacting layers each having the grain running at right-angles to the bursting stress on the joint and parallel with each other, said contacting layers being reenforced by the second layers cemented thereto, each to each, said second layers having their grain running parallel with the bursting stress on the joint and parallel with each other; and metallic fastening means passing through the four overlapped layers thus formed and adapted to carry the bursting stress from one second layer to the other second layer and to relieve both said rst layers of bursting stress.

2. A joint between two bodies of wood, each body comprising two layers of wood cemented to gether to form a single structure, the rst or contacting layers being each of substantially onehalf the thickness of the second layer and each said first layers having the grain running at rightangles to the bursting stress on the joint and parallel with each other, said contacting layers being reenforced by the second layers cemented thereto, each to each, said second layers having their grain running parallel with the bursting stress on the joint and parallel with each other; and metallic fastening means passing through the four overlapped layers thus formed and adapted to carrythe bursting stress from one second layer to the other second layer and to relieve both said first layers of bursting stress.

3. A longitudinal joint between adjacent edges of contiguous portions of a cylindrical wooden barrel, the edges of the portions being complementarily cut away to substantially the central plane to permit them to overlap; each of said overlapped portions comprising two layers of wood cemented together to form a single structure, the first or contacting layers being each of substantially one-half the thickness of the second layer and each said first layers having the grain running atright-angles to the bursting stress on the joint and parallel with each other, said contacting layers being reenforced by the second'layers cemented thereto, each to each, said second layers having their grain running parallel with the bursting stress on the joint and parallel with each other; and metallic fastening means passing through the fourA overlapped layers thus.

and to relieve both said rst layers of bursting stress.'
