Specification of Letters Patent.

Application filed May 25, 1906. Serial No. 318,637.

j Bodies. of which the following is a specification.

The present invention relates to a new method of lining the interior sides, walls, or the like of hollow bodies, which are formed in a known manner of bending layers 5f wood lued together, thefibers of the layers crossmg one another. i The purpose of liningthe hollow bodies is to protect the wood against the action of the contents of the hollow bodies. As lining material thinsheets of any optional metal, galvanized or enameled paper, textile material prepared in the same or similar. manner, linoleum, or any other suitable material may be employed.

Heretofore the hollow bod of wood has been made as an independent ody in a wellknown manner on a bending-machine, the

finished wood vessel bein lined with an indeendent body made of sheet metal, &c. ven by the neatest workmanship it was impossible to fit or adapt the lining closely on all sides of the wood. The lining must therefore, if it is to be durable, be made in a greater thickness of material, thus making the lined cask exceedingl heavy. Such lined bodies have another dzacided defect, in that the different materials of which they are composed, being only in slight relationship to one another, under 0 movements due to said materials quite in ependently of one another. Therefore loose places appear and spread at places of the most difference, conformably to the character of both bodies, and are naturall exceedingly difficult to discover and to c ose. All these defects are only perfectly avoided by firmly gluin the linin material to the fiat plate of woo before ending on the beading-machine. This combined plate being as one piece is then bent on the bending-machine in the form of a hollow body. The lining side of the plate forms the interior of the hollow body.

The plate of wood consists of one or more layers, the fibers of one layer crossin those of another layer. If it is desired to ave a wood, consisting "of one or more layers of wood, is bent around the first plate and glued with the same and in such manner so that the union of the second plate is displaced with relation to the union of the first plate. The connection of the lining material with the wood layers, which on account of the gluing is a very intimate'cne, becomes exceedingly perfect in being bent through the pressure of the different materials on one another which thus takes place. The finished vessel thus appears as being made of one piece. 'The one material strengthens the firmness of the other, and the disturbing influence of difl'erences in temperature is thereb greatly reduced. I

In t 1e drawings accompanying and forminga part of this specification is illustrated one form of construction as showing an example of making a cask in accordance with the presentinvention, and in which Flgure 1 is a plan of a composite sheet for forming part of a vessel. Fig. 2 is atransverse section on the line as y of Fig. '1. Fig. 3 is a plan of the finished vessel, artly in section and Fig. 4 is an end elevation of the finished vessel.

Figs. 1 and 2 show a plan and cross-section of the fiat sheets of wood I), c, and d, glued to the thin sheet of metal a, by bending of which the cask is to be made. The sheet of wood I) is in the present instance narrower than the other sheets, so that the sheet metal is bent up and down at two right angles, as at e and As will be seen from Fig. 3, these bends e and f form a suitable sup ort for mounting the end members 9 and b in the finished bent cask. These members g and it also consist of several layers of wood '8, 7c, and Z, glued together, so that the fibers of one layer cross those o'f another layer, and around the cylindrical part and on the inside of which the sheet-metal covering 'm is attached. The cylindrical part of the sheet-metal covering an lies against the sheet metal a, and both can be soldered to one another, forming an airtight joint. As is usually done, more protective rings n and 0 can be fastened at the inner surface ofthe periphery of the cask.

It will be seen from the cross-section of the cask in Fig. 4 how the unions of the lining and of the sheets of wood, glued on one another, are preferably distributed. The union v IOC ' Oyer that is the union got the sheet of wood,

afiixed to the .sheet -Hmetal casing. The' unions 1 ands of the other sheets of wood are,

however, arranged displaced from union g from one another. While the construction of parts described in the foregoing specification are preferred, it

is to be understood that numerous changes of construction and operation may be made without departing from the spirit and scope of this invention, and it is to be understood a that the same is not limited by the positive terms employed in connection with the description excepting such as the state of the art may require.

What I claim as my invention, and desire to secure-by Letters Patent, is

1 A method of lining the interior of hollow bodies, bent of one or more layers of wood, the fibers of which cross one another,con

sisting in firmly gluing the lining material to a flat plate of wood and as one piece bending the same on the bending rnachine to a hollow body.

2. A method of lining the interior of hollow bodies, bent of one or more layers of Wood,

the fibers of which cross one another, consistmg in firmly gluing and lining material onto afiat plate of wood, and asone piece bend 'ing the same on the bending-machine to a hollow body, the lining material adapted to form the inside surface of said hollow body. 3. A method oflining the interior of hollow senses "bodies, bent of one or more layers of wood, 3,

the fibers of which'cross onejjanother, consistingin firmly gluingthe' lining material onto a flat plate ofrwood', and as onepie'ce bending the sameo'nthe bending machine to a hollow body, the lining material adaptedto form the inside surface of said hollow body and com posed of sheets of imperviousm'a't'erial.

4; The r'nethodofforr'ning a hollow body consisting of gluing together a layer of wood and a layer of sheet metahthen bending such 4 secured layers into the form ofjacylinder, then putting in endmem-berspand joining the longitudinal meeting edges of the metal lining by soldering. I

'. '5. The method of forming a hollow body 5 consisting of gluing together a layer of wood and a layer of sheet metal, then bending such secured layers into the 'form of a cylinder, joining the longitudinal meeting edges of the metal lining by soldering, and then putting 5 in end members composed of a layer of Wood and a layer of sheet metal glued together and uniting the metal lining of such end membars to the metal lining of the hollow body by soldering. I 6

In testimony whereof I have signed my name to this specification in-the presence of the two subscribing witnesses.
