- 1 '0 all whom it may concern:
having tapering rolls fitted to a conical huh Be-it known that 1,- CHARLES S. Loon woon, a citizen of the United States, residing at 289 Market street, Newark, countypf Essex, and State of New Jersey, have 111 vented certain new and useful Improvements in Roller-Bearings Having Grooved Rolls and Tension-Bands, fully described and represented in the following spec fication and the accompanying dra wi.ngs,- forming a part of the same.
This intentionrelates to a roller bearing and embraced b -aconical casing so that the rolls Ina-y e cieiitly sustain end thrust, and the objectof the invention is to .hold the rolls elastically in place upon-the hub while permitting a slight expansive movement of the rolls thereon. This object is attained by forming each rollwith a shallow groove upon its periphery about the middle of its length, and fitting to the-serieso'f rolls an elastic band of greater width than thickness, which embraces the rolls at the several grooves, so as to prevent; any material ex pansive movement of the rolls.
, The tension hand IS 'SO proportioned that any end movement of the rolls tends to are'keptin asuit-able path upon the hub to straighten the curvature of the bandbetween the-peripheries of adjacent rolls, which permits a slightelastlc movement of the rolls when subjected to sufiicient strain-.- The rolls retain the tensionha-nd in the grooves, by
an inwardly facing shoulder formed upon" a collar atthe srmi'ller end of the hub,- the smaller endsof the rolls contacting with such Shoulder in their normal movement "yields sufliciently to permit," the crowding slightly: elevated collar -'which formsfgtheshoulder. at the smaller end of 'tlhe;hub,'while jssah'o'ut the hub. The 'space between a .coni
cal hub and. conical casing is of tapering form, so that end thrust upon the'hub tends to. force the rolls upwardly upon thei'rre- :s'ective conical's'eats, andlgthe elasticity of. t e tension band-produces an elastic resist ance to suehupwardmoirement and prevents the rolls fromyielding' materially, while it' yields 'ys'ufiiciently to avoid abrupt shocks,- when the hub subjected to suddeIi'thrust.-"
The elasticity of the teiisionhand also "perform's another important tunction as it of theseries of rolls upon theihubflo'i er the embre'eedlbi' h a ercnce to the annexed drawing, in which Figure 1 is an elevation of the hearlng with the casing removed; Fig. a longi-.

where. it is shown with conical seata and aform a slight inwardly-facing shoulder r-.'

Each roll e is formed-with a peripheral groove of greater width than depth having a Hatedge f and afhereled edge 7', and'a tension band g is fitted to the grooves and to the saidvedges-andencirclesihe huhis illustrated separately in Fight collar b at its smaller end proportioned to.

The invention will be understood by ref- "The larger end of the hub is r abheted, forming an outwardly-facingshoulder d and a seat 4 upon-the hub. v A. seriesof rolls e is fitted to the hub and encircled by'a casing e all of the rolls, so as to-retainthem-u on. the hub in contact Wit-lithe shoji'ilderscl-v he tension band as shown in Fig,- 3 isfa continw point and it is thereforehensi-blefl t s great Strain pplied internally, Th

lugs areibe'nt-to fit; the sides of "the rollsloosely, asshownrin Fig)? \v r It is obvious that the tension band cannot be-appliedto-thje rolls afterftlieya're assembled upon-the hub, and it is therefore neces;
sary to fit the "rollswithin the cage and apply the tension bandto the. grooves,- before the hub is inserted in the rolls.
In assembling the 'ca e With the rolls, the
tension band is firstp aced over the cage,'
the rolls inserted through the apertures from' the'inner side of the cage and engaged. with the tension band, and-the lugs l upon the cageare then bent to prevent the escapev of 'the rolls, thus inakingthe band, thejcage,
and the -rollsa unitary struct-ure'whiclrcan be handled without the derangement of its parts. The rolls can then'be forced-over the collar b at the smaller end of the hub; as shownin" Fig.5, the tension "band yielding, or in some measurestraightening between .the sereral rolls as indicated in Fig. (5, to
permit such expansion of'the rolls.
The tension band operates when the rolls have been slipped over the collar to draw them into' their, normal position upon the hub \i'itlrthe'ir smaller-ends in cont In Fig. 6, two of the rolls-are shown and the tension band Stretched straight between the rolls, althoughthe-bandis normally ofequal curvature at all points, as. shown in Fig. 3. Such flattening of the curvature between the several rolls is resisted elastically by the metal of the band, Which is madeof greater vldth than thickness so as to be flexed'm some degree between the rolls when snflicient force is applied. Such flexure of the band is not in practice so great as that shown in Fi- 6, 'where the-band-is represented tangential to the rolls merely to illustrate the nature of the fiexure and D not its extent. The construction of the band.
enablesitijto elastically resist. expansion of the rollswith nicreasmg resistance as the rolls move upwardly upon the hub. andforms. rigid obstacle to their movement beyond a certain limit, as the ring embraces the series of rolls positively and is not split.
or divided to permit its yielding indefinitely. Inthis respect it differs n'iaterially from rings which have. been split upon one side and applied to rolls in a manner similar to n'iy divided ring, for the mere. purpose of holdingrolls upon a hub while assembling the parts ofthe bearing.
In such a construt-non, the split in the mug permits it be readily expanded for slipping over a series of rolls after they are assembled upon the hub, which as i'iotpossihle with an unact with s'i'msa' asides. ring, such is" teen-ted, ante efinitely limit the present construction to d outward expansion of; the rolls.
It will be'observed that the tension'liand is applied to the rolls intermediate their ends so that any retarding effect which the- :ban' may have upon the rolls does not tend to. twist'the rollsout of their normal rela'-' tion to the' hub, which sometimes results when'aguiding device is applied to one end only of the rolls.
The present construction is especially adapted to what is termed ahigh-duty bearing in which a heavy load m'ust be sustained by relatively short rolls, for want;
of -space to apply a long bearing; and such short rolls have a greater tendency" than' long rolls to twist outof line within the bearing, Y By applying the tension band to the middle of the roll it has no tendency to retard one end of the roll more than the other, and thus produces"no tendency to twist the rolls out of place.
Having thus set forth-the nature of the invention what is claimed 'herein is 1. In a roller bearing, the combination, with a conical hub havin'gjan inwardly facing shoulder near its smaller end, of a series of tapering rolls fitted to such hub with their smaller ends against such shoulder and having each a shallow .groove' about the middle ofits length, and an undivided annular flexible tension band fitted to such groove and arrangedand operatedt o hold the rolls vagai'nst the said shoulder and to elastically resist certain expansive movements of the rolls upon the hub, and positively prevent the expansion-of the rolls beyond a certain limit.
2. In a roller bearing, the. combination, with a conical hub having an inwardlyfacingshoulder near its smaller end, of a series of tapering rolls fitted to such hub and having-each a groove at the middle (if its length, an annular flexible tension band of greater breadth than thickness fittedto" such grooves, and a cage having a conical shellwith apertures to admit the rolls, and
a flange upon the cage en 'aging such hub, toguide the cage and rolf ment.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
