This invention relates to the art of expanding cylindrical sheet metal bodies, such as steel barrels, drums, and other shipping containers, and comprises a new and useful means for producing annular corrugations orribs in the cylindrical wall of such containers to strengthen the same and to facilitate rolling .movements' thereof: The object of the invention in general is to provide a machine which will produce a plural number of such circumferential ribs of" substantial size in separate "zones simultaneously, or in other words, concurrently in a single'expanding operation.
The machineis therefore constructed with separate sets of dies adapted to move outwardly'on radial-lines from a common axis to expand the cylinder uniformly in two places, and'at least one set of dies is adapted to move longitudinally of the axis in that operation, to permit the stock todraw or flow lengthwise of the cylinder. Thus as the cylinder 1 is stretched or expanded circumferentially by the dies in'two sep'arated places or zones the stock flows freely from the opposite ends of the cylinder towardfeach zone'or area of expansion, and drawing of the stock'atthe "middle of the cylinder is also effectively permitted, all 'without impedance or hindrance f from the dies and without causing the middle 'orexpanded portions of the cylinder to be weakened or rupturedl In the" accompanying drawings, Fig. 1 is a side elevation of the machine, and a sectional view of a plaincylindersleeved over the dies, and Fig: 2 isja-similar view with the dies and cylinder expanded. Figs. 3 and 4 are side elevations of aplaincylinder' and a .corrugated'cylinder. Fig." 5 is ahorizontal section of the machine on linef5-5 of'Fig. 6. Figs. 6 and"?arelcorresponding sectional views "of themachine in a vertical plane, showing the dies-contracted and expanded as in Figs.-1and 2, respectively. Fig. Sis a top viewof the machine. Figs. 9'tosl2 are nection with gearing 4 suitably arranged to I 5 with the lower end of a reciprocable shaft orthrust rod' 8 which extends through and is supported verticallywithin a bearing 9 in a bed or base plate 10 at the top of frame 2.
detail elevations and sections-on a larger scale of one of the upper die segmentsand the llft -rotatea crank or cam shaft5 at'a slow speed,
sayone revolution for each cylinder expanding-operation. An eccentric strap 6 connects the crank, cam or eccentric portion of shaft In practice the base part of the machine is placed in a pit with base plate 10 onalevel with the floor of the work shop. The remaining working parts of'the machine are projected above the floor and comprise inpart a relatively long sleeve 11 on was and a flanged nut 12 in screw-connection with the upper screw-threaded end ofrod 8. Tie rods 1 4, coiled springs 15, and nuts 16 secure sleeve 11 in suspensory connection with flanged nut.

Separate sets of toggle linksllSare pivotally secured to channeled pieces '19 screwed arranged radially in respect to-thrust rod 8 and' formingseg'mental parts of a complete circles Members 20 embody'ribbed feet or supporting extensions22adapted to slide in and upon the radially channeled: top of bed 1 plate 10 and these members are secured for slidable movement on the base plate by means of a top bearing-ring 23 and tie, rods 24,see

' bers 20 supports a pair of'dies or die-sections; a fixed die section 25 and a relatively movable die-section 26, the latter being spaced apart and mounted to move toward the first diesection. As shown,eaeh movable die-section 26 is formed with a rabbeted slot 27 extend- "lengthwise to the'fiat-sides or faces-of sleeve 11, and the outer-ends 'ofthe toggle links of each set are pivotally connected toa series of individually movable die-carriermembers. 20
.- lVhen cylinder as shown in Figs. 5 and 6.
ly to the fixed set of die sections 25, as,
delineated in Figs. 1 and 6, and both sets of die sections are ribbed to permit annular beads-or corrugations to be produced in a plain cylinder A whenall suchsections are simultaneously expanded. Thus the fixed die-sections have outwardly-extending ribs 31 arranged in a circlea predetermined distance-above the ribbed feet 22 of carrier members 20, and. the longitudinally slidable' die sections 26 having similar bead forming ribs or projections 31 annularly thereof at or near their. lower ends. The spacing of the ribs 81 and 31' may be varied, but as shown these ribs are. spaced substantially equidistant from each other and the opposite ends 'of a plain cylinder A after it has been sleeved over said dies and placed upright upon the ribbed feet 22, say as shown in Fig.1. I v
A is in place as stated the dies are contracted, that is drawn inwardly Starting of the machine will revolve the eccentric shaft and in the first half revolution thereof draw rod 8 and sleeve 11 downwardly, thereby straightsuing the toggle links 18 and forcing all. of the die-carrying members 20-outwardlyin unison. As the dies move outwardly the bead-forming ribs 31 and 31' engage the inner wall ,of cylinder A and expand the same circumferentially. Such expansion of the sheetmetal simultaneously at the two separated places draws the outer ends aa of the cylinder toward the ribs, and the middle belt or area a of the cylinder is also effected,
Such narrowthat is, it becomes narrower. ing'of the cylinder beltis possible because the slidable dies 26 are free to. move with the stock toward the fixed dies and the neces- -sary'stock for forming relatively deep ani a plain cylinder.
nularbeads or corrugations 6 is also thereby provided without stretching or rupturing the middle area or belt a. of the cylinder. Obviously,-both*sets of dies might be madeto slide relatively to each other, but asingle set has beenfound to function satis- ..factorily where only two beads or corrugations are being expanded simultaneously in The expanding operation is complete'd'in one-halt revolution of the eccentric or crank shaft, and the remaining part of the revolution restores the working parts to the same position as at the beginning with the ribbed cylinder released and free to be removed from the contracted dies.
What I claim, is:

A machine -for expanding cylinders, comprising coacting and radially shiftable rigid devices adapted to, expand a sheet metal cylinder circumferentially at spaced places therein, said devices being arranged to move longitudinally in respect to the 'axisof the cylinder coincidently with the longitudinal flow of the material in the area between the places being expanded.
