aceessto the rollers for the'roller system; and. a

relative movement of the rolls, and to other features of construction anti arrangement which Will more definitely appear from the following description and claims.

In the appended drawings. which represent a preferred embodiment of invention,'

Figure 1 is a view in elevation;

Fig. 2 is an end view from the left in 3 Fig. 1;

F lg. 4 a vertical transverse section on the line ieit, 1;

Fig. 5 a vertical longitudinal section on the line Fig. 4.;

6 a vertical transverse section through an end view from the right in roll and is turned. about an axis which is fixed relatively to the frame.

The shattS which forms the outer roll or carries a separate roll is mounted in a %ii t able frame 9 normally above the roll 6 so that, the distance between the rolls may be varied as the thickness of the material pressed hetween them fliminishes.

The shiftahle frame 9, which forms a material part of my invention, comprises a cross-web 10 carrying journal-boxes 11 and 5 12, respectively, at its ends. The journalboxes have cylindrical surfaces to slide along; the walls of curved openings 13 and 14, in the upright frames 1' and 2. To form. an extended guide for these journal-boxes, the frames 1 and 2 are formed with flanges i and 16., respectively; The journal-boxes 1 and 12 are preferably made iii separate pieces and attached to the cross-web 10 in any suitable manner. as by bolts 17. it is thus seen that the frame 9 and with it, shaft 8, can be shified toward and away from the shaft 6 for the purpose above specified.

The cross-web is designed as tively brace the shaft or roll. 8 against bending stress. To properly limit the space be tween rolls 6 and 8 and thus determine the thickness of the ring to be pressed, l have provided adjustable stops. As a convenient means for that purpose I have shown bolts 15 and 16, as best shown in These bolts extend from the unilerside offlanges l4 upwardly through the bem'ingliloclrs 7, i of the roller 6. Normally, they are at their upper cud Hush with the upper face of these boaring-blocks. llhen it desired, however, to space the rolls 6 and 8 for a greater thick ness of the hoop. the bolts are advanced so that they protrude above the surf. cc of the bearing blocks 7', 7. a required amount. For the purpose of adjustment the bolts are provided with a smooth portion 13 and a. s :IcW iillI'QtHlPil pol'ijlflllx il adapted to engage a scrmv-tln'czu'l in the flanges 14-. A lock-nut 17" is prorii. al for each bolt to secure the bolts in adjusted position. These stops are importa at, as by their proper adj ustmcnt. the pressure rolling of the blank is stopped just at such time as the outer periphery of the finished ring, IOOQas shown in Fig. 6, comes into engagement with the guide rolls. Dis tortion of the ring is thus prevented and the production of a perfect ring insured.

While any suitable mechanism may be resorted to for operating the journalcarrying frame 9, I have shown as a? preferred fern-i of such mechanism a lever 18 fulcrumiui on a shaft 19,--whicl1 will be more particularly referred to bclow,--said lever haying a short arm 20 connected to the crosswch 10 and its longer arm connect-mi to a source of pressure This source of pressure is pnxferalily a hydraulic engine. but its spccil'l form in immaterial and does not form a. part of my in-- vention. It has the fimction of t shaft 8 towzird the shaft 6 and supplying the power necessary for the rolling procc It is understood that there are means, as customacv. for relcasuiu;- the pressure at will. This feature is not illustrated, since it is well understood. The lever 18 is preferably mounted on shaft 19 by means of a. divided hearing, as clearly shown in dotted lines in Fig. 4, so that the lever can be attached and detached without disturbing other parts of the apparatus.

The shaft .19 is supported at its ends in the upright end portions 1 and of the frame in such a manner that the wear is taken. up principally by hearing caps 93" and 9.1. For this purpose the in a 21 and 2).. a'sis seen in Figs. 2 and '3. cml'srace the nutjor part of the lower bearing the wear becomes excessive, i re ilacecl by to eii'ec- 23 of the frame,

iln-ough gears a new cap with little expense, while the frame itself is little affected. The caps are held in position by bolts 19 and by arms 22" which are in. turn clam )ed in a bifurcation as by olts 90. This form of mountinq makes it possible to take out shaft 19, wien desired, and to give access to tl interior of the machine for purpose of repair. I

For the power transmission for turning the shafts (l and 8 and thermvith the rolls.

have designed a simple set of gears and the particular arrangement-forms an. im port-ant part of my invention.

1e frame presents at its left-hand edge (see Fig. 2) a, substantially vertical wall. This wall is shaped to form three half bearings 23, 24: and The other half for these hearings is provided in the form of detachable caps 26, 27 and 28 (see Fig. 6). bearings are identical on each of the upright end portions 1 and 2 and accommodate shaft- s 29, 30 and 31.

Slmft 29 carries a fly-wheel pulley 32 for a belt :lrixc and a pinion 33. This pinlmi, meshes with a gear 34 on shaft 30, see Fig.

1-. On shaft 30 are two pinions 35 and 36' to transmit the power from shaft 30 to shaft through gears 37 and 38. Gears 3} and 38 in turn mesh with gear-teeth 39 and 4:0, respectively, on shaft 6, as best shown in Fi 4 and 5.

The gear-teeth 39 out directly into the is an important feature, since it reduces the distance between the shafts or rolls 6 and 8 to a minimum and thus makes it possible to roll exceedingly thin rings between the rolls proper. It is of course possible to reduce the distance between the rolling surfaces to any small amount desired by providin rollers larger in diameter than rolls 6 and 8, but I have found that the increase of the rollers in diameter is not desirable. since they have a tenrlenov. due to their high circumferential speed, to tear and dis-- rupt the fibers and texture of the material of the ring. I have avoided i'lis iliiiii-ulty by reducing the distance between the aha-Firs or rolls to the smallest possible amount From shaft 31 the power is also transmitted to shaft 8 through a gear 41 at the end of shaft 31 which projects outside the frame port-ion l, the gear 41 meshing with a gear keyed to shaft 19 (see Fig. 3) and 43 and 44 on shaft 19 cugaging gear teeth 45 and 46, respectively. on sl'iaft'8. It will be noted that these gears +15, 46 are located close to the bearings, and that the bearings are relatively long, so that transver:.-1e and torsional strains are counter noted. The location of the cars 45, 4.6 in the shaft. enables the shafts to be made very strong and of substantially the same the sha or amiable-aim in ill qn'odueet-l on the ed eter. There very little tendency for lateral or side-Wise metal-flew. thott-he Width of the ring remains substun ully the some. Any slight irregnlmiifies whit-h tend 'to he s or the rings are how-- ever prevented by the 1. that the ring us it is rolled is kept with its unis purullel to the axis of the rolls, beeuusr of .ihe faret that its edges bear against; the plates (5:5 and 70, which also prevent any sidewise Web tiling of the ring being rolled. llhe massive structure of the standard and the support 2-, together with the mnple bearings afforded for both ends, and pmrtieuhn'ly the outer ends of each of the rollers insure he pro duction of a substuutially perfect ring with its inner and outer faces in puredelism.

It will be notel'l that the upper roll 51 is slightly larger in diameter than the loud-n. roll 52 end. this feature purp at zulopted, it?? it has been foun that it slightly greater eircumfertmti:rl L l of the outer i or pressure roll (muses more ell'ectire and uniform distribution of the metal.

It "will also be noted that in my muehme the press-n1 1s applied to the outside roll and this is done for the reason that'I have found in practice. that a greatly superior resul t is obtained by this arm.s'igemem'.

' While I have Sl'lOWIl a machine adapted for rolling u plain. or pm'ellehsided ring, it is obvious that many other forms may be rolled, by suitable changes in configuration of the rolls. Exumples'of sueh forms are shown in Figs. 1-11.
