may be rolled; in which said rings can be reduced to any desired thickness or width by an easy rolling action; in which a beaded or ribbed ring may be rolled and in which a ring may be' flanged.

It is a further object of this invention to provide an arrangement of rolling elements defining substantially a closed way for act ing substantially upon the same cross-section of a ring, that will avoid abrading the metal; that are readily adjustable, and that will avoid fringing or sliver-ing the'metal, and that will avoid bulging or distorting the ring.

It is a still further object of this invention to provide a ring support with rolling elements that are readily adjustable for retaining different sized rings and which is automatically adjustable with respect to curved abutments so designed as to alwaysmaintain said'rolle-rs in proper relation to the ring that is being, rolled.

'lVith these and other objects in view which will become more apparent in the following description and disclosures, this invention comprises the novel mechanism and combinations hereinafter described and more particularlypointedout and defined in the appended claims.

Referring to the drawings,there is shown a suitable frame for supporting the various parts of the machine comprising a horizon tal support or table 1 upon which a ring. support? is s'lidably secured. In the present instance, the ring support has underhanging flanges that engage the side margins of the table 1 as shown in Figure 3. This ring support is formed with a plurality, four in the present instance, of radiating arms'2 which are equally spacedf Guide grooves 3 (Figure 5) are formed in each arm, and slidable shoes 4 and 1 are positioned in said grooves. The inner ends of these shoes are bifurcated in a horizontal plane and rolling element 5 having lower flanges 5 are journalled in said bifurcations. The shoes 4 are provided with outwardly projecting ribs ('3 which are always :111811- gagement with the cam members or curved abut-ments for any adjustment of the shoes and support 2; .-aswill later appear; The curved abutments 7" are bolted to a support constituting afj'part of the machine frame.

These 'gears' areprovided with cylindrical margin. Thering 57 thatit is desiredfto mon driving gear 46 secured'upon a vertical shaft 47 journalled in the bearing 44, and in the movable bearing 25, the upper end being journalled in a bearing lug48 on the machine frame. The vertical shaft supports a bevel gear 49 in mesh with the gear 28 of the upper tapered roll 29 and. forms the drivingineans therefor. The lower end of the vertical shaft 47 supports a second bevelled gear 50 in mesh with a bevelled gear 51 upon the driving shaft 52 to which power may be applied through a gear 53 thereon. The pre-. viously mentioned bevelled gear 54 that meshes with gear 23 is supported intermediate the ends of the shaft 52. It is accord ingly obvious that the drivingshaft 52 with the described gears affords means for simultaneously rotatin the tapered rolls and the exterior roll 43. is there will be more or less of a wedging action between the roll 43 and the friction elements 45 flas above explained on account of the pressure against the roll 43 which is loosely mounted upon its shaft for movement transversely of its axis as shown in Figure 4, the rotatable frictiondriving effect will be ,increased,-so that said friction hubs may exercise a strong rotative effort upon the roll 43 in its operative relation'with the ring to be rolled. The tapered rolls and the outer cylindrical roll 43 are designed to approximately rotate at the sameperipheral velocity so that there will be no; appreciable drag or abradant action upon the ring that is being rolled.

If it is desired to roll av ring with a bead or rib, one of the tapered rolls may be stepped as shown in Figure 7, whereby a reduced conical or tapered portion 24 is formed upon the lower tapered roll 24?. The supporting shaft for the roll 24' is also shown as made in sections just as the shaft 22; the lower roll being-secured upon a section 55 having a mortise and tenon connect on withthe section 56, the juncture being sheathed by a slidable collar 55"; the lower section being freely slidable from its bearing 20. r-Accorch ingly the tapered roll and its stub shaft may be readily substituted for the roll 24 shown in.

Fgure 2, if the rolls 24 and 24? are not readily removable for interchanging, purposes.

In some cases, it may be desired to form a flange upon a ring. In Figures 8 and 9 1.

have illustrated an arrangement for accomplishing such a purpose; In such a case, I

use as a part of the apparatus, a ring member119. having a rabbet extending from one of its margins, preferably the upper .inner flange is positioned in the rabbet of thezring member with the margin to be flanged extending beyond the inner periphery of the ring 19 This extending margin may be.re-. duced asshown if'so desired. Theinterior cylindrical roll 3l has a lower bevelled sur: face and it is shown above the ring'57 with a part extending into the recess in the'end of Y the tapered roll 29. Now by properly. varying the pressure, tl'leroll 31 may be drawn down bending the projecting portion of the ring 57. The roller 31* is adapted to be drawn down into the position shown inFig ure 9. The supporting ring is engaged by the tapered rolls 24 and 29 the latter of which also engages over the-ring 57 and by 'the'exterior cylindrical roll 43, and as these rolls are rotated as before explained the rings 19 and 57 will be rotated conjointly and the interior cylindrical roll 31 will flange the ring 57 against the inner periphery of the'supporting ring 19 as shown in Fig. 9. It will of course be understood that the roller 3B may be substituted for the roller 81 when such a flanging operation is desired. It is for this reason that the tapered roll 29 is shown in Figure 2 as provided with an end recess. 9

In referring to Figures 2, 7'and 10 it will be noted that the interior cylindrical 'roll 331 overlaps the end of the tapered roll 24, and

that it is in turn overlapped by the upper tapered roll 29. The exterior cylindrical roll 43 overlaps the upper tapered roll 29, and is in turn overlapped by the lower tapered roll 24. It will be noted that these four rolls dew 'flne substantially a closed way through which too the ring rotates, and that they act upon the ring in substantially the same plane of crosssection somewhat in thenature of a die. i

This particular structure is important since it prevents outward bulging of tliering, injurious distortions and waste which continually arise wheresuch rollers are circumferentially spaced of the ring. .It is therefore evident that the rolls acting upon the rin that is being-rolled may be readily adjuster of the metal of the ringmay be reducedto any desired size. It will be appreciated that if the rolls were circumferentially. spacedand did not define a closed way, the.

res

ring might bulge between such circumferentially spaced rollsand becomeso distorted that it would result in waste, especially if light rings were being rolled. Such bulging and distortion ofthe rings will be substantially obviated in the use of my improved construction. Such a construction will also avoid fringing and slivering of the rings."

It will of course be understood that the rolls arev contracted and expanded throughuthe fluid operated pistons ormotors, as is" well known in the art. 1
