IVIACHIINE FOM SHPING CAP-BANDS.

Specification of Letters Patent.

Patented Aug. 22, 1905.

Application filed May 1905. Serial No. 259,080.

To LLZZ whom if; may concern.-

Be it known that I, J ULIUs BRENZINGER, a citizen of the United States, residing at Mount Vernon, Westchester county, State of New York, have invented new and useful Improvements in Machines for Shaping Cap-Bands, of which the following' is a specification.

This invention relates to a machine for providing a straightflat strip of metal with a flange along one edge and for bending' the strip into a curved shape. The band thus formed constitutes the means for securing a cover to a bottle, jar, or other receptacle by encircling the bottle-head in such a way that its flange engages beneath the head while its upwardlyextending fiangeless portion is upset against the cover. In this way the band and cover collectively form a cap which by the upsetting operation is securely locked to the bottle.

In the accompanying drawings, Figure l is a front elevation of my improved machine for shaping cap-bands; Fig. 2, a side elevation thereof; Fig. 3, a horizontal section on line 3 3, Fig. l; Fig. a, a detail of the shaft-bearing; Fig. 5, a section on line 55, Fig. l; Fig. 6, an enlarged end view, partly broken away, of the shaping means; Fig. 7, a section on line 7 7, Fig. 6. Fig. 8 illustrates the blank to be shaped by the machine; Fig. 9, a side view of the finished band; Fig. 10, a section on line 10 lO, Fig. 9; and Fig. 11, a plan of Fig. 9.

The blank A, Fig. 8, having a finger-piece A', is by the machine upset along its upper edge to form flange A2 and is also gent into a circular shape with overlappin,5 ends, as shown in Figs. 9 to l1.

To the frame B of the machine are journaled a lower shaft a and an upper shaft Z, such shafts being driven in opposite directions by pulley c and gear-wheels a' b. Upon shaft ci is mounted a cylindrical roller (Z, the hub cZ of which is clamped to the shaft at LZ2. Above roller Z there is mounted on shaft b a coperating roller e, which is held yieldingly against roller ZZ in manner hereinafter de- Roller e is provided with an outer circumferential flange e', that projects slightly beyond the face of roller d, Fig. 7, the distance between the flange and the roller corresponding substantially to the thickness of blank A.

In order to present the blank to the rollers,

a feed-table f is arranged in front thereof and at an elevation corresponding substantially to the top of roller (Z, Fig. 5. The blank is guided along table f to the roller-pass by an outerflangef' and an inner adjustable rail g, Which extends with its end into a circumferential groove e2 of roller c. The blank is held against the surface of table f by a transverse keeper g on rail g, beneath which the blank is inserted. The distance between flange f and the inner face of flange e determines the width of the flange A. In order to set the machine to form flanges of different widths, the table is laterally adjustable by means of slots f, accommodating clampscrews f3.

By the means described the blank A when passed between the rollers Z and e will be provided along its outer edge with a flange A2, Fig. 7. To bend the band thus flanged into a circular form, there is arranged back of roller Z a curved deflector t, the inner Working face t of which is concentric to roller (Z. The deflector i projects above the roller-pass to grasp the front of band A and passes with its upper end into a circumferential groove e" of roller e.

As the band emerges from the pass it will by deflector L be bent concentric to roller Z and will thus be taken along and wound upon the same, Fig. 6. A stripper Z, hav ing a pointed and beveled working edge c, that projects across the end of roller CZ, is encountered by the flange A2 of band A when the latter has partly encompassed rol-ler (Z. In this way the band properly flanged and bent is thrown laterally off the roller and into a suitable receptacle. (Not shown.)

The rollers cZ and e should be driven with the same circumferential speed, to which effect the diameters of gear-Wheels a b/ correspond to those of rollers Z e, respectively.

The roller e, as has already been stated, is held yielding'ly against roller ZZ, so that the blank is taken along by frictional contact with the rollers. To e`ect this result, one of the shafts is journaled in yielding bearings, the' drawings showing the shaft Z) to be so journaled. As represented, the shaft b turns in bearings j and 7c. The bearing 7' is flanged, as at j', and is slidable between upright rails B of frame B. A set-screw f2, tapped into a fixed cross-piece B2, bears against a plate jl, between which and bearing j a cushion j* is 2. A machine for shaping cap-bands provided with a cylindrical roller, a cooperating flanged roller, a deector, and a stripper having a pointed and beveled Working edge projectng across the end of the cylindrical roller, substantially as specied.
