SPECIFICATION forming` part of Letters Patent No. 781,742, dated February '7, 1905.

Application led June 4, 1904. Serial No. 211,216.

To /r/Z wlw/n it 71u01/ concern:

Be it known that l, H ERMANN ROMNDER, a citizen of the United States, and a resident of Milwaukee, county of Milwaukee, State of Illisconsin, have invented certain new and useful lm provenients in Tube-Making Machines or Presses. of which the following is a specification.

My invention relates more particularly to machines or apparatus in which under simultaneous inliucnce of heat and pressure sheets or plates of material, generallyv in the form of two a more ply wood-veneer plates of any desii-ed thickness and curvature, may be pressed and the overlapped portions thereofl forced into intimate union with each other to form practically seamless hollow tubes which may be used for a great variety of purposes.

The objects of my invention are to provide an etlicient, economical, and rapid machine of simple construction and comparativelyv low cost by the use of which, first, the overlapped portions of substantially bent or curved sheets or plates of material, as wood-veneer plates consisting each of a number of layers of wood or wood veneer glued together under heat and pressure with reversed grain by means of any suitable waterproof cementing compositionsuch, for example, as a compound of glue and potash--may be united and glued together under the influence of heat and pressure and by means of any suitable waterproof cementing composition applied to the overlapping parts, and, second, the said plates of material pressed to assume and retain a curved form with a curvature of greater or less pitch, as desired, resulting in the formation of hollow tubes which are practically seamless and combine simplicity and cheapness of construction with greatest strength and durability and which may be used as pipes, conduits, or cylinders or for the mantles of barrels, drums, and other like packages and for various other purposes.

To these ends my invention consists in the Afeatures of construction and devices hereinafter described, and more particularly set forth in the appended claims.

The preferred form of the invention is illustrated in the accompanying drawings, forming part of this specification, wherein like characters of reference indicate like parts throughout the several views.

The drawings illustrate more particularly my improved machine as adapted for the manufacture of barrel-mantles; but l do not, of course, limit myself to the production of this class of articles only, as the same apparatus may also be applied for the purpose of producing tubes rfor a great number of other purposes.

Figure l is a front elevation of a machine embodying my invention, partly in vertical section, showing a tube compressed between the extended inner block or core and the several press-plates. Fig. Q is a vertical sectional view of a portion of the apparatus, showing the tube loosely on the collapsed core and the outer press-plates in reversed position,(whcn the press is open.) Fig. 3 is a vertical section on line :c ,r of Fig. l. Fig. et is a plan view showing the frame work,the hydraulic presses, and the wedge.

A is the framework, consisting chiefly of a suitable casing with a base, side and rear portions, and top plate forminga rigid structure which the movable parts are mounted on and connected to in suitable manner, preferably as hereinafter shown and described.

B, C, and l) are sections or sectors which together form the expansiblc and collapsible inner block or coreI on which the material to be compressed is placed in any suitable manner and which when expanded has an outer circumference equal to the inner circumference of the finished tube. The sector B has an extension E at its rear portion, by means of which it is suitably secured to the rear portion of frame A, and thus becomes rigidly connected thereto. The sectors C and Dare slidably connected with each other and with sector B and movably held in relative position to each other by suitable means, as pins or guiderods b. F is a wedge horizontally movable between the said sectors B,U, and l), supported by the framework A and sector B, and arranged to reciprocate horizontally by suitable means, as the cog-wheel e, suitably mounted on the vframe A and meshing' with the rack or gear-rail (l, provided on the rear portion of IOO wedge F, the said cog-wheel being actuated l by suitable means, as pulleys M, from a source of power. (Not shown.) rPhe surface of wedge F facing the core -scction B is preferably straight or flat, correspondingto the meeting surface of sector B, and the surface of wedge lF facing the core-sections C and D is tapering, corresponding to the tapering meeting' surfaces of sectors C and D. By these means lthe sectors C and D may be raised and lowered and the core expanded and collapsed as the wedge F is moved forward and back, and the sectors B, C, and D and the wedge F may be provided With suitable longitudinally-extending tongues and grooves c or other means to assure a uniform expansion of the core and a true alinement of the said movable parts.

G and H are pistons each adapted to be moved horizontally through the action of Huid-pressure introduced into the cylindercasings I I, both cylinders being fed by one press-fluid supply or feed pipe f, whereby both these presses operate simultaneously. The pistons Gr and H may be arranged to slide horizontally between the base and the top plate of the framework A in any suitable manner, as shown in Figs. 1 and Q, so as to prevent binding.

K is a v-ertically-reciprocating piston movable in cylinder-casing L, which is fed by a separate supply-pipe g, whereby this press may be operated independently of the horizontal hydraulic presses.

The pistons G, H, and K, as well as the top plate `of the frame A, are provided with suitable pres's-plates M, N, O, and P, integral therewith or detachably connected thereto by suitable means, as bolts or screws, each of the said press-plates having' a concave surface conforming to the convex surface of the portion of the core facing each of the said pressplates. Each of these press-plates M, N, O, and P and the sectors B, C, and D is preferably hollow and provided with flues or openings R R, arranged to be heated by any suitable means, as electricity, gas, steam, or other means. In the drawings the press-plates and sectors are shown to be heated by means of steam entering through inlets it /z/ and discharging through outlets e', whereby the pressing-surfaces may be heated to the desired degree to act upon the material a to be pressed and upon the waterproof cemcnting composition applied to the overlapping portions of the material to be joined under heat and pressure. These press-plates M, N, O, and P and the said core-sections B, C, and D may all be heated to a uniform temperature suiicient to heat the material and permit the bending thereof to the desired form and the joining of the overlapping parts, or the core-sections may be heated to a considerably higher temperature than the press-plates, so much so that the surface of the material e exposed to the said core-sections will become charred to a greater` o r less degree, as desired. Vhen thus charred on the inner surface, the tubes formed of this material may be utilized for mantles of liquor or wine barrels and packages or other purposes requiring charred surfaces. This material a consists, preferably, of a number of waterproof wood-veneer plates or other suitable material with overlapped portions la, which are designed to be glued and pressed together between the pressing-surfaces of the pistons and the core-sections under suflicient heat and pressure, continued thereunder for a suiiicient time to enable them to set and become virtually integral with each other. the waterproof cementingcomposition with which the overlapped portions have been coated binding them together to one practically homogeneous and seamless piece of material. Any suitable waterproof cementiug composition may be used for this purposev-such` for example, as a compound of glue and potash.

Suitable means, as counterweights S S, resting' when released on brackets Z Z, mounted on or detachably connected tothe framework A, may be provided to return the pistons of the horizontal presses as soon as the hydraulic pressure is released.

l/Vhen the material t isv intended to form a tube to be used as a barrel-mantle, suitable hoops fr fr and bung-plates s s may be simultaneously connected and pressed to said material, and in that case I provide suitable recesses n n in the pressing-surfaces of plates M, N, O, and P to accommodate the hoops /1' i' and bung-plates s s, and in practice I preferably place the material so onto the core that the hoops and bung-plate are cemented to and cover the overlapped portions of the mantle and are pressed together therewith by the vertical hydraulic press.

The operation of my improved machine is as follows: The machine standing idle, the wedge F being in its eXtreme outer position, as shown in dotted lines in Fig. 3, the core being in its collapsed position, and the horizontal and vertical presses being open, as shown in Fig. 2, the material a required to form the tube is placed in position over the core, the overlapping portions of the material having' previously been coated with any suitable cementiug composition and the hoops i' i' and bung-plate .v having been tacked on or otherwise placed and held in position on the material in case the tube is to be used as a barrelmantle.

The wedgeF is then moved forward' IOO lIO

by means of the cog-wheel c until it reaches covered by the curved surfaces ot the pressplates N and O against the inner core. Then the vertical press is started by operating teed or supply pipe y. when piston K, with its press-plaie P, compresses the bung-plate s and the hoops` r r and the overlapped portions'A ot` the material against the coie and forces them into intimate union. rI heapparatus then stops and is allowed to stand, exerting this tixeil pressure until the overlapped portions ot' the material/i have assumed permanent union and the material becomes practically one continuous homogenous and seamless tube impervious to moisture and atmospheric intluences and thehoops r r and the biing-plate s have also been glued to or otherwise united with the tube, it being understood that the press-plates M, N, O, and P and the core-sections B, C, and D are sutticiently heated during the pressing operation by means otl steam circulating through the tliies or chests R Ror otherwise to bring aboiittlie desired result under simultaneous heat and pressure, and the tube may be charred to any desired degree on its inner or outer surface, or both, by means ot increasing the temperature of the pressplates )L N. O, and P or the core-sections l, t, and l), or both` suiiiciently to accomplish this purpose. The vertical hydraulic press is then opened, the piston K sliding downward ot' its own weight as soon as the Huid-pressure through pipe y is released. Then the horizontal hydraulic presses are opened, the water-supply through pipef being sluit otl, the pistons G and H returning by means of the ci'ninterweights S S or other means provided tor this purpose. Then the wedge E moves back to its previous outer position by the reverse action ot cog-wheel c, when the core collapses, and the tinished tube may then be taken trom theapparatus by lit'ting it trom the collapsed core, the said material f retaining the exactshape it has assumed between the press-plates and the core-sections under heat and pressure and the overlapped portions ot' the material having practically bef come one homogeneous piece ot' material, the said material thus t'orming a practically continuous and seamless tube ot desired shape. lly inserting and suitably securing to the pistons and the traine A press-plates and coresections having surt'aces with a curvature ot greater or less pitch the same machine may be used tor Yt'orming and pressing' tubes with larger or smaller diameter and ot' cylindrical, oval, or other desired shape.

By means ot this machine I am able to torni two or more ply wood-veneer plates or other suitable material and unite the overlapped portions thereof, so as to produce tubes suitable t'or pipes, conduits, barrel-mantles, or other structures ot' any desired shape and size in which curvature ot' greater or less pitch is desired and to char one or both surfaces ot said tubes to a greater or less degree,

as may be required. when they may be used t'or any ot' the purposes above stated necessitating charred surt'aces.

This invention is susceptible ot many modilications, and the details ot' operation and construction ot' this machine may be varied trom the above description without changing the principle otl my invention so long as sheets or .plates ot suitable material may be bent and pressed therein to assume and retain a curved torni ot' greater or less pitch and the overlapped portions joincd and torced into intimate union with each other` so that the material will t'orm practically continuous and seamless hollow tubes. i do not, thcret'ore, limit this specitication and the claims to the precise Jforms ot' the invention illustrated in the drawings and hereinbet'ore described.
