Tov @ZZ whom concern.-

Be it known that I, HUBERT M. PERRY, a at no1s, have inventedcertam new and useful Improvements in Side Bearings for Cars, of which' the following is a speciiication.

This invention relates to improvements in side bearings ofthe antifriction type, and

has for its objectto provideimprovements in thel details of construction, the same general type of side bearing being shown and described in my prior patent,l No. 806,360, issued December 5, 1905.

The objects of the invention, more speciiically stated, are to providea construction in which a singlepiece casting forms at once a; completehousing of the antifriction-rollers in so far as the latter are in'closed, to provide an improved construction which enables the rollers orl supporting-wheels to. be seated within the housing with small portions only oftheir peripheries protrudingwitho'ut providing a removable top for the housing, to provide an improved construction which enables the base ofthe accommodate itself to the su porting-timber u on which it is mounted an avoids liability ci) breaking the bearing by reason of inac'cu rate fitting ofthe base to its support, to prov vide a sim le and eiiicient means for securing in the matters hereinafter described, andy the j ourna -pins upon which the supportingrollers rotate in place withput resorting to threaded or other expensive connections, and in general to provide an improved construction of the character referred to.v

y To the above ends the invention consists more articularly pointed vout in the appended) claims. l

The invention will be readily understood from the following description, reference being had to the accompanying drawing, in which* Figure 1 is a plan view, with parts in hori zontal section, taken in a .plane coincident with the axis of the journals of a preferred embodiment of the invention. Fig;` 2 isl a view partly in side elevation and partly in central longitudinal vertical section. Fi 3 is a transverse vertical sectional view ta en throu h the axis of one of the main supporting-w eels. Fig. 4-is a vertical section on bearing to more readily` line a. b of Fig. 1, omitting the roller and its ,journal-pin.

Referring to said drawing, l designates as a whole a.boxlike base member made open at its lower or base side and provided4 with an integral top or cover portion 2, suitably apertured, as indicatedat 3 3, to permit the peripheral portions of the main supportingrollers 4 to preferred construction shown the main casting is provided with laterally-opposite horizontally-projecting extensions 5, which are epertured, as indicated at 6, to receive the bolts, whereby the bearing is secured to its su port.

he main supporting rollers or Wheels 4, of which there aretwo, are mounted upon cylindric journal-pins 7, which are arranged with their axes inclined sli so'as to respectively coinclde with radii from the pivotal center of the truck. -As a novel feature of construction each of these journal-pins is arranged to extend entirely through one side of the housing, as indicated protrude therethrough-` In. the

ghtly to each other, i

at 8, and into a socket 9 in the opposite side of the housing, which yextends only partly `through the side wall thereof. At the points where the journals are seated in the side Walls of the housing the latter are thickened or provided V which serve the double purpose of affording a larger bearing for the journal-pin and of confining the .supporting rollers or wheels 4 against endwise movement.

The interior of each supporting-wheel is larger than the journal-pin upon which it is supported, and. a series of small cylindric rollers 17 is arranged to occupy the space between said parts and constitute roller-bearings between the same. small rollers is slightly less than the axial length of the main wheel or roller within which they are arranged,

fine the small rollers in position Washer-like plates 11 are seated in each end of the larger roller concentric with the journal-pin, as seen clearly 1n Fig. 3.

The journal-pins ,7

are fxedly seated in the housing and are con` veniently fastened in position by forming a small -recess in the peripheral portion of the `outer end of after the pin is' seated in the housing the adjacent perimeter oi`l 'the aperture is peened The length of the the pin, as indicated at 12, andwith annular ribs I0,

and in order to con- IOO ' down into the recess 12, asindicated at '13 of in position. .once to lock the journal-pin against rotation Fig. 2,*so as to, in`eifect,rivet the journal-pin This simple expedient serves at and to hold it against' endwise movement Withinits seat..

vAs a further detail of improvement make the peripheries of the main supporting-rollers 4 convexin cross-section, as best seen in' the 'sectional view, Fig. 3. Preferably-this `con'- vexity is provided by forming/the periphery of each Wheel .With a central narrow cylindric portion 14 and -inclimng the remaining 'surv1lacesof the periphery to form slightly-conical surfaces' 15. The object of this construction is to insure al vbetter distribution v of the Weight upon the Ijournal-pins and in this manner betterldistributethe Weight to the main supporting-casting. I

The ,fcon'struction describedv has, iamong others,the'following advantages, namely: It 1 vdispensesl With the necessity of making a re.-

movable top plate for-the housing, thereby lesseningthe cost, ,and .it alsoprov'ides acon- 'vexA or turtlefback.' housing upon `Which dirt and detritus-'arenot llikely to accumulate. It provides amplespacefor all dust and dirt to accumulate in theybottom of the housing Without .interfering with the 'freedom of movement of the supporting-Wheels, and when thehousing or base member'is supported upon a timber which is apertured-to correspond with the open bottom of the lhousing, as Will usually be thev case, the dust andl dirtv fall through Without lodging. The parts may the latter, and in generalthe construction is such as to afford high e'fiiciency at a minimum cost.

Mesos I claim as my invention-- l. A side vbearing for cars comprising a box-like base member 'provided with an integral cover portion. apertured for the-periphery of-'the' main supporting-roller and having an opening at itslower'side through which the mainl roller may be inserted, a

journal-pin mounted thereon, and an openended main roller mounted upon said journal 'and having its periphery protruding through and above the cover .portion of the housing, a

'series of rollers mounted Within said main roller-'around said journal-pin, and a pair of f 'Washers mounted' within the ends of said main roller concentricallywith the journal-f pin and confining the smaller rollers.

'Y 2. A. side bearing for cars comprising a,

box-like base member provided with an inte-' gral cover portion apertured for the periphery of the mainsupporting-roller-and'having an opening Vat its lower side through-Which the main roller may be inserted, a journalpin mounted thereon, andan open-ended main roller mounted upon said journal and above thecover porti-on ofthe housing, said journal-pin being inserted through one .side of the housing and into-but not through the opposite side ofthehousing, and suitable means/ for confining said journal-pin immovably in place."

`3. A side bearing for cars', comprising a box-like base member 4provided with lan iiitegralv cover-*portion apertured for .the periphery ofthe main supporting-roller and having an opening in .its lower side through having its periphery protruding, through and. i

which saidmain roller may be inserted, said base memberl having comparatively light side .WallsL thickenedl vjournal-pin bearings4 formed integral with the opposite side Walls in axial alinement, said thickened bearings being formed by 'inwardly-projecting annular bosses.; and a journal-pin, the lends of which are seated within said thickened bear# ings.
