To all whom t may concern.-

Be it known that We, RICHARD A. BRIGHT and VALTER A. PECIQ-citizens of the United States, residing at Providence, in the State of Rhode Island, have invented a new and uset'ul Improvement in Flexible Rolls foi-'Cigar- Machines, of which the following is a specification.

Our invention relates to that class of tieni-1` ble rolls for cigar-machines which is made of a spirally-wound coil of wire, which is held in a longitudinally-curved position to iit the contour of the cigar-bunch and roll the binder or wrapper thereon. IIeretofore such rolls have been made of uniform diameter throughout, except at the terminating tip, which operates to roll the tapering head end of the cigar, the tuck-forming portion of the roll having a diameter as great as that of the middle portion, which is notthe proper construction for rolling cigar-bunches with tapering tucks, the increased surface movement of the roll at the tuck end of the cigar-bunch tending to twist the bunch, thus causing the cigar to draw hard in smoking. Moreover, it is entirely iinpracticable to wind a continuous spiral coil to form a flexible roll for cigar-machines upon an oppositely-tapered mandrel, so as to reduce the diameter of the tuck-rolling portion, and then to withdraw the inandrel from the spiral coil. We have therefore divided the iiexible roll into two separatelyformed sections, the one tapering from the middle portion toward the head end of the cigar-bunch and the other taperingin the opposite direction toward the tuck end of the same, and have connected these two portions to each other base to base to forni the oppositely-tapered portions of the roll. IVe are thus enabled to make a spirally-wound roll tapered in opposite directions by winding the tapering port-ions of the roll upon separate suitably tapered mandrels, whereby the diameter of the roll at any specific point in its length can be made as desired.

Figure 1 represents a side elevation of a iiexible roll for cigar machines constructed according to our improvement, the two oppositely-tapered sections being connected by interlocking the spiral wires. Fig. 2 represents thesame with the enlarged middle portion of the roll broken away to show a transverse section of the interlocked wires. Fig. 3 represents the roll as shown in Fig. 2, the interlocked wires at the base of the tapering rollsections being supported by means of a coupling. Fig. 4 represents the roll and shows the tapered sections connected base to base by means of a separate spiral coil. Fig. 5 represents the roll and shows the tapered sections connected by means of a screw-threaded sleeve, Fig. 6 is a detail elevation showing one form of the closed joint at the junction of the oppositely-tapered roll portions. Fig. 7 represents the joint of the roll as formed upon a sleeve having a collar at its middle portion.

In the accompanying drawings, A represents a portion of the roll-holding head of a cigar-machine; B, the movable jaw which carries the upper rollor rolls, and C is the curved shaping-core, which is firmly held at the movable jaw B.

The 'spiral roll D is made in two oppositelytapered sections a and b, the wire of which is Wound upon separate tapering mandrels, so that the severaldiameters of the roll .at speciiic points between the head end of the cigar-bunch and the tuck end of the same can, if desired, be made proportionate to the corresponding diameters o'f the bunch at the4 same points. The surface of the roll will thus in its rotation conform to the surface movement of the inclosed bunch, so that the twisting ot' the said bunch will be entirely avoided. The oppositely-tapered roll-sections a and b can be connected to each other base to base, so as to form a continuous flexible roll, by screwing the properly-squared ends of the roll-sections together, so that the wires w w of each respectively will become spirally interloclied, as shown in Figs. l and 2, and then soldering the said wires to each other; and in order to add strength to the joint and to preserve the two roll-sections in their proper axial line With each other while being soldered We preferably employ an interior coupling c, as shown in Fig. 3, which is also soldered to the joint. In the employment of the oppositely-tapered IieXible ci- IOO gar-machine roll D it is desirable to be able to separate the two sections from each other, and to reunite them at pleasure; and in order to provide means for thepractical accomplishment of this object we wind up the roll-sections ct and b of round wire, and also wind of the same size wire aspiral-coil coupling d, as shown in Fig. 4, and then screw the tapering roll-sections a and b onto the coil d, thus forming,` the joint by means of a screwcoupling; and instead of the spiral coil d a rigid coupling CZ, provided with a screwthread e, which is adapted to t the interior couvolutions of the wire, can be employed, as shown in Fig. 5; and instead of tapering the ends of the wire of the opposite sections a and b, as in Figs. l and 2, We prefer when employing the screw-coupling to out the end of the Wire square, as shown atf in Fig. (3; and instead of making the enlarged ends of the tapering roll-sections to rest against each other at the joint they can be separated by a collar g upon the periphery of the coupling` d., as shown in Fig. 7, the end of the wire of the roll-sections being preferably tapered, as in Figs. l and 2,so as to abut squarely against the side of the collar. The roll-section l) is continued at the same diameter from the tuckrolling portion 7L to the head A or movable jaw B, and provided with the attached gear t', which engages With the gear upon the drivin g-shaft E, and serves to impart rotary movement to the roll. The flexible spirally-wound wire roll thus formed is removable from the fixed supporting-core upon which itis caused to revolve, and will tit cores of different shapes.

`We claim as our inventionl. A flexible spirally-wound Wire roll for cigar-machines, made in two tapered sections which are united to each other base to base, substantially as described.

2. A flexible spirally-wound wire roll for cigar-machines, made in two tapered sections which are united to each other base to base, and having,r a connecting-joint strengthened by an interior coupling, substantially as described.

3. A eXible spirally-Wound Wire roll for cigar-machines, made in two tapered sections which are united to each other base to base by means of an interior screw-coupling, substa-ntially as described.

4. A flexible spirally-wound wire roll for cigar-machines, made in two tapered sections which are united to each other base to base by means of an interior coupling provided with an exterior collar, substantially as described.
