To all whom "it may comm:
f-Be it known that'I, Trmnnnus M. Boces resident of Monongahela, in the county of 1n Tools for ,Finishin Washington and State of Pennsylvania, have invented a new and useful Improvement hereby declare the .fdllowing'to be a full, clear, and exact description thereof.
' This invention relates to a tool for finishthe interior of bearings and the like. he object of the invention is to provide a convenient tool which will effectively remove the tool marks and compact and smooth the inner surfaceofthe bearing.
I rough and also softens the same. Usually the bearings are finished with the boring, and no further work is put on the same, exce t filing or scraping by hand.
- y tool is intended to roll down the in- 'ner surface of the bearing after the boring, so as to obliterate the tool'marks and to smooth and compact or' harden the surface so as to reduce friction and wear in'use.
The tool'is so constructed that the roller can be'readil contractedand expanded to fit bearings 0 different sizes.
The invention comprises the construction ,and-arran ement of parts hereinafter deis a side view 0 line Fl 2;.and Fi s is a longitudinal section showing a m ification.
The tool comprises a suitable body or 'ma'ndrel 1 havin a shank 2 preferably ta;
w Newmanai'asrnrmmsfsfia the i 6 so that it can fitted in the chuck of an ordina dril or boring machine. This mandre is provi edwith an enlargement or disk 3 havin a substantially flat outer end face 4. Pro ecting from the disk is a journal portion 5 located eccentrically w1th referencetothe axis of the mandrel; Fitted on this journal portion so as torotate-there onis a roller carrier or sleeve 6 whose-bore is eccentric therein. This slee'veis slotted'in from one end through its bore to form a was: FOR FIIINTISHING'JBEABJZKJQISQ V Specification ot Lett ersratent. Application-filed Kay 14,

seat '7 for the. roller 8, which is-constructd preferably of cylindricalshape 'so' asf to" present a smooth surface to the inner facet of 'the bearing to be polished. I This roll co seat 7'does not extend for the full length; of the sleeve, so as to leave oneend por -J: tion 9 solid. 'The seat 7 is of circulanfo'rm in cross section, asshown in Fi' 5,. oi'that'f the roller 8 cannot escape ra iallyff'lhe'fi roller is inserted by slipping it in endwi'se .before thesleeve is put-onthe journal}; 1 said roller bein held between the soliden df wall 9 of the s eeve and the disk .'onthe'. mandrel. The seat 7 o ens'intdthe b'oriofi thesleeve' fi so thafit cylindrical rollerl I '7 contacts with the journal*portion" 5.

"The" disk 3 is provided withgraduations, 11 to assist in thezadjuetment ofthe r'ol er. I After haviif position the sFeeve is clamped in suitable means, that shown comprising a tap vi screw 12 entering .a threaded openi-ng'in the end of the journal portion 5 and havin'gits head bearing a ainst the end'of, thesleeve' This sleeve is jightly longer than the j0urnal 5', shown in Fig. 2, so that when the tap screw 12 is set tightly thesleeve is clamped between the head of the screw and the disk 4 of the mandrel. I i For the smaller sizes 'the construction so far described willsufiice, and Fig. 6 shows such a too'lf li'or larger sizes it is preferred rte use some special means for adjusting the sleeve dangularly on the journal. This means comprises a worm wheel 14. cut in they surface of the outer end of the journal 5, which worm wheel is engaged by a screw of worm 15 moimted transversely in the sleeve 6 in any suitable manner, as at 16, to provide engagement for a key or the like for turning the same. This worm and worm wheel serve to adjust the sleeve ang-ularly, after which the sleeve is clamped in position by the screw 12.
-been adjusted to' i prop In finishing bearings, they are, as usual,
I bearing offering less friction clamped in the chuck uf a boring machine and the interior then bored out to a true circle. The boring tool is then removed and the tool above described substituted therefor. The sleeve 6 will be adjusted angularly on the journal 5 so as to bring the roller 8 out far enough to finish the particular size of bearing which is bored. This tool is then inserted into the bearing and the boring spindle rotated in the usual Way, thereby carrying the roller 8 around and around in contact with the interior surface of the hearing. The consequence is that all marks of the boring tool are entirely obliterated and the metal thoroughly smoothed, compacted and hardened. This gives a and subject to less wear in use than if the rolling was not resorted to.
What I claim is:
1. A tool for finishing the interior of bearings and the like, comprising a mandrel, an eccentric portion thereon, a roller having a smooth surface adapted to compact the bearing surface, and a roller carrier fitting the eccentric portion and adjustable angularly to thereby move the roller radially with reference to the axis of. the mandrel.
2. A tool for finishing the interior of bearings and the like, comprising a mandrel provided with an eccentric journal portion rigid therewith, a sleeve fitting said eccentric journal portion, a substantially cylindrical roller carried by said sleeve, and means for adjusting said sleeve angularly on said journal portion.
3. A tool .for finishing the interior of bearings and the like, comprising a mandrel provided with an eccentric journal portion, a'sleeve on said journal portion, a substan- :ially cylindrical roller carried by said sleeve, means for adjusting the sleeve angularly on said journal portion, and means for clamping the same in its adjusted position.
4. A tool for finishing the interior of bearings and the like, comprising a mandrel, an eccentric journal portion thereon, a sleeve fitting said journal portion and adjustable angularly thereon, said sleeve being provided With a slot therethrough, and a roller seated in said slot and bearing against the eccentric journal portion.
5. A tool for finishing the interior of bearings and the like, comprising a mandrel provided with a disk, a journal projecting from the disk with its axis eccentric to the axis of the mandrel, a sleeve on said eccentric journal and having a slot extending from one end through to the other endsolid, a roller bearin against the eccentric ournal portion in sai slot be tween said solid end of the sleeve and disk on the mandrel, and means for clamping the sleeve in different angular positions.
6. A tool for finishing the I interior of bearings and the like, comprising a mandrel provided with an enlargement or disk, a journal projecting beyond the disk and being eccentric to, the axis of the mandrel, a sleeve on said journal, a roller carried by said'sleeve, and a clamping means carried by the journal comprising a member overlapping the sleeve and adapted to clamp the slamle between itself and the disk on the man- In testimony whereof, I the said THAD- onus M. Bocos have hereunto set my hand.
