JOURNAL BOX AND MOUNTING.

Specification of Letters Patent.

Griginal application filed April 27, 1920, Serial No. 376,971. latentlihflfimfiw, dated March 1, 1921. Divided and this application mea December 14, 1920. S eha1 No. 430,680.

To all whom it concern:

Be it known that I, Lao 'K. Srarronn, a citizen of the United States, residing at New York, in the county of Bronx and State of New York, have invented new and useful .use in connection with anti-frictional bearing meansbetween a car wheel journal and the journal box therefor. In such constructions, it is absolutely necessary that the bearings, and consequently the box carrying the bearings, be at all times retained in longitudinal alignment with the journal. Otherwise the bearings would create friction between the journals and the bdxes which would render the bearings defective, subjectthe same to breakage, and cause injury to be inflicted to both the journal and to the box. As is well-known in railway construetions, it is frequent that the rail on one side of a track is disposed at a greater or less elevation than the rail on the other side of the track, and as the wheels of the rolling stock must at all times follow the rails the truck frame or mounting for the journal,

box must necessarily be of a character which will yield laterally on the box to compensate forsuch irregularities in the rails of the track'and not influence the journal box, with respect to its longitudinal alignment on the axle, to prevent'unnecessary friction between the roller bearings, the journal and the box, or damage which would otherwise be inflioted'to such parts. i

It is therefore to be considered the primary object of the present invention to roduce a. journal box which carries a-nt1- rictional rollers that engage with the jourr'ial or spindle or" the axis for the wheels of rolling stock, and a mounting therefor which is.

susceptible to lateral angular movements n the box without. ailecting the longitudinal alignment of the box on the journal.

It is a still further object of the invention to produce journal box for the journals on the wheels of railway rolling stock and a mounting therefor, in which fulcrum means is provided between the mounting, and the box which will permit the mounting to assume angular" positions with respect to the box, when thawheels of the rolling stock pass over irregular track surfaces, and wherein the degree ot the angle assumed by the mounting will be limited by means between the mountin and the box.

It is a still further objectto produce a ournal box which carries anti-frictional hearings to enga e with the journal on the wheel of a railway rolling stock, wherein a fulcrum engagement between the top of the box and the to of the mounting is produced,

and wherein t e means that secure the box will appear as t e nature of the invention is better understood, may be accomplished by a construction, combination and operative association of parts, such as is disclosed b the drawingswhich accompany andwhic form part of this application.

In the drawings Figure 1 is side elevation of the improvement parts being broken away and parts being in section.

Figure 2 is a side elevation illustrating a slight modification.

Figure 3 is a front elevation of the box shown in Figure 1, with parts broken away and parts in section. Figure 4 is an elevation looking toward the front of a journal box of a slightly moditioned on amounting such as 1s commonly employed for supporting. the journals of 'fied construction, showing the same pom-- it will be seen that anti'frictional rollers at face of the wheel, an

bearings and the mounting of said box on the truck in a manner which will permit of a limiting rocking or lateral angular positions of the mounting on the truck when. irregularities with respect .to the height of the rails on the track are encountered. All such devices which have come under my observation have been worked out in accordance with the theory as applied to the anti-frictional bearings between the spindle of 'a shaft and the ordinary vehicle wheel,

in which spring supports are provided be tween the axles and the body of the vehicle. In railway rolling stock, the journal or spindle of the axle is rejected beyond the the truck frame or hearing support for the journal boxes and for the body of the rolling stock, while yieldable with respect to the said body, are not susceptible to a slight swinging or lateral movement on the boxes. Consequently, the-longitudinal alignment of the roller bearings in the boxes and the journals with which the same engage are materially interfered with, creating friction andd'amage to parts, and rendering the roller bearings not only defective but absolutely inoperative so that the same are positively impractical and detrimental in the use for which they are designed.

As the description progresses, it will'be readily seen by those having knowledge of the art to which this invention relates that I have successfully overcome the deficiencies above referred to, and that also I have provided means whereby friction between the journal and" the journal box of railway stock is reduced to such an extent that the car or coach may carry a far greatrir weight without liability of damage to the wheels, journals, journal boxes and supports therefor, than has heretofore been a'ccom 'ilished.

Referring. now to the drawings in detail, the numeral 1 designates the journal or spindle end (if an ordinary axle for the wheels of railway rolling stock. The journal 1, of course, projects beyond the outer face of the wheel (not shown), and has its spindle end received in a journal box 2.

By reference to Figure 3 of the drawings,

are disposed in circular series between a bushing 5 that is swaged on the journal I spindle 6, and a bushing 7 that is swaged to the inner face of the journal box. Of course, other arrangements of anti-frictional bearings may be providedbetween the box and spindle. v

The box. in the showing, in Figures 1 and 3 of the ,drawings is designed for use on freight carrying cars. The box 2, at its top. and at the center thereof has a lateral projection in the nature of :1 lug 8. and this 1,4.os,oeo

and at its top and bottom. portions is provided with outstanding ears 9 and 10 respectively, and each of the said ears has an elongated opening 11 therethrough. The sides of the box, between the ears 9 and 10 are formed With ribs 12 respectively. These ribs, from the central. portion 13 thereof are inclined outwardly, providing angle walls or shoulders 14 which terminate in the end walls provided by the outstanding ears 10. Thus the centralportions of the confronting faces of the ribs 12 are pointed.

The mounting for the box is in the nature of the usual frame. In this connection, it is thought desirable to state that except for the journal box, no changes are made in the car construction. The upper bar 15 of the mounting rests directly on the lug 8, while the lower bar 16 of the mounting is disposed a slight, but-'sutiicient distance from the bottom of the box to permit of a lateral swinging motion or yielding of the mount-' ing on the box without permitting the lower bar 16 being brought into contact with the box, or otherwise interfering with such movement of the mounting.

Passing through the upperand lower bars of the mounting, are bolts 17. The respective pairs of bolts pass through the elongated'openings 11 in the ears 9 and 10 and are received in the. channel provided be tween the ribs 12. On the bolts, and having their ends contacting with. the bars 15 and 16 respectively of the mounting, are sleeves 18 respectively, the said sleeves contacting or being only slightly spaced away from the central pointed portions 13 of the angle ribs 12, The btilts 17 are engaged by nuts 19,

The upper hfir pf the mounting has a fulcrum engagement with the, top of the journal box, incident'fto the engagement of the said bar with the-Jug 8. The means which secures the boat-to the mounting, that is, of course, the brilts and the sleeves thereon, being arranged in the channels between the ribs 12, haven fulcrum engagement with the points 13 of; the said ribs. Thus the mounting may rock or yield laterally with respect to the journal box, and such rocking or yielding will be limited by the contacting engagement of the sleeves 18 with the angle walls 14 cf the ribs 12. When the mounting is at its extreme angular positions on the journal box, one side of each of the sleeves 18 will be in contact with either the upper or 1 0 lower angle surface onbne of the ribs 12,

and the opposite side of the said sleeves will he in contact with the diagonal o posite angle surface on the other r1b12. hus when in such position, both sides of the sleeves are engaged by the ribs, but at opposite points.

The sleeves relieve the bolts from undue strain.

ImFigure 2 of the drawings, the journal 1 is received in a journal box 21 of a slightly 380 diilerent construction from that above described. lhe journal box 2 has its sides provided with spaced ribs 12' arranged in opposed pairs. The ribshuve their central portions hickened upon their ,lill'lfil confronting faces and are beveled or arranged at opposite outward inclinations from the central portions l3 thus provided the angle walls to the opposite sides of the central points 13",beinr indiciitcd by? the numeral 1%. topper the box, bets on the spaced pairs of is provided with a projection in the nature of u lug 8" l .ch is rounded from its center to its edges, T he mounting for the box has its ends rovided with yolres, whose?- depending patrol elarms 18 are received between the spacodpairs of ribs 12, the upper element 15' of the yoke resting on the lug 8", and the lower ends of the yoke, which project s suitable distance below the -ournel box 2 being connected by u plate 16. With this construction, the ears 9 and 10 are dispensed with, as are also the untifrictional rollers which surround thcbolts that connect the plates 15 and 16 in the mounting previously described.

Iii the remaining figures of the drawings, the journal box 20 has its sides provided with the spaced pairs of ribs 21, whose inner faces. are disposed at opposite angles from the central point 22 therefor. The ribs 21 are spaced a further distance apart than are the ribs 12, for the reason that the ribs 21 receive therebetween the flat side members 23 of the yoke 24 that is employed in the usual construction of truck frames on passenger coaches. The top of the box 20 has a. transverse cross sectionzrlly rounded lup, thereon, and the said top, at the sides of the lug are provided with upstanding flanges 25. Between these flanges, and resting on the fulcrumed lug 52 i, is the end of the equal iz'ing bar 26 of the mountihg construction. T be lower bar 2'? of the mounting secured, in the usual manner to the ends of the yoke 24, and is spaced from the bottom oi the journal box 20, as clearly disclosed by the drawings, so that's rocking or lateral movement of the mounting on the box will not be interfered with,

.ln both forms of my improvement, it will be noted, ample provision is made for positively retaining the untidrictionel roller bearings carried by the journal boxes in proper and positive engagement with the spindles orjournuls of the wheel carrying axles, as well as the positive longitudinal or parallel arrangement of the box with respectv to both the journal spindle and the roller bearings. With my improvement, the wheel of the rolling stock will, at all times, and under all conditions follow the rails of the track, and as a consequence, the deficicn- "cies above recited are not only effectively overcome but the danger of derailment which is always occasioned by the tread portions of the Wheels of the rolling stock not positively ,engs ingthe heads of the rails, is also eifective y overcome.

While I have illustrated and described a satisfactory embodiment of the improvement as itnow appears to me, it is to be undcrstood thut such departures may be made therefrom as fall within the scope of What is claimed.

Having described the iifientlon, I claim 1..- In combination, a journal box and a, mounting therefor, means on the journal box engaging the mounting, and providing a fulcrum thercbetween, means assing through the mounting and contacting the sides of the box for connecting the box to the mounting, and means on the sides of the box at the opposite sides of the connecting means for engaging the latter for limiting the rocking movement of the mounting on the box.

2. In combination, a, journal box and a mounting therefor, fulcrum means between the upper surface of the journal box and the mounting, means passing through the mountpassing through the members constituting the mounting and contacting with the sides of the boxfor securing the latter on the former, said box having its sides provided with s passage for the reception of said securing means, and the walls of said passage being disposed at an outward angle from the center thereof, as and for the purpose set forth.

4. In combination, a journal box and a: mounting therefor, the latter including members which are arranged over and below the box, a transverse rounded lug on the top of the box contacting the upper member of the mounting sud providing a fulcrum therebetween, ribs arranged in spaced pairs on the sides of the box, and having their l. 3. ll

journal for thewheei of it railway car, and a journal box therefor, in cembination with the jnurnal box and a mounting for the box, of means carried by the b0)? providing a ful- 5 cru m between said box anti mounting, means carried by the mounting securing the journal box thereon and means carried by the jour- 1131 box dispo l sed opposite the conneeting means for e aging the latter when the mounting is e bjeeted to a lateral rocking 1 movement on? the box.

In testimony whereof I aflix my signature.
