Application filed. January 20, 1913. Serial No. 743,127.

Be it known that I, 'OHARLESIDUNNING, a

citizen of the United States residing at fication, reference beinghad tothe accompanying drawings.

--This invention relates to' new'and' useful improvements in journal bearings for railway cars and the like, the object of the invention being to provide a simple and practical divergent roller hearing which may be readily substituted for theordinary bearings now in general use on steam and electric railway cars, street ca'rs'and similar vehicles'.

Anotherobject of the invention is to'provide" a bearing of this'character which will possess advantages in points of efiiciency and durabilit is inexpensive of manufacture and at t e same time is simple in construction and operation.

the invention consists in the novel features of construction and the combination and arrangement of parts hereinafter more fully described, ointed out in the claim and shown in t e accompanying drawings, vin whicht Figure 1 is a side elevation of a-journal bearing constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view taken on line 2-2 of Fig 4. Fig. 3 is a transverse sectional'view taken on. the line 33 of Fig. 1. Fig. 4 is an end eleva- H v I My-improved journal bearing comprises a bod l which is preferably similar in size and s ape to'the ordinary journal now in 'use' so that it may be readily substituted for the 'same, and it is com osed of two sections 2 and 3, the latter 0 which is adapted to fit in a recess 4 in one end of the former and to be retained therein by a screw, bolt or similar fastening 5.- Formed in the bottom of the body 1 is the usual semi-cylindrical recess 6 adapted to receive the journal or axle, but the latter instead of contacting the wall of said recess is engaged by the anti-friction rollers 7 arranged in cylindrical cavities 8 formed in the inner portion of the section 2 .and having portions in communication with the recess 6 so that the pe- I ripherie's of said rollers project into the latter as clearly shown in Fig. 3. I v

At'the ends of the rollers 7 are reduced trunnions 9 and 10, the former of which are disposed in openings 11 formed in the closedend of the section 2 concentric with the cavities .8.

The other trunnions 10' are arranged in similar openings 12 formed in the other section 3, which latter, as above stated, isaremovably arranged in the recess 4 so as to permit of the insertion of the rollers 7 in the cavities 8 and of their removal therefrom. It will be noticed that the recess 4 is in the form of atransverse channel extending across one end of the section 2 of the body and that the section 3 closes the open ends of the cavities 8. When i the section 3 is in position and secured by the screw 5; its openings are concentric with the cavities 8. v i

Threaded in the openings 11 and 12 are the sleeves l3 which-are'provided upon the interior thereof with the annular raceways i 14 adapted to receive annular series of anti- With the above and other objects in view,

ings.- Arranged between the openings 11 1 and 12 at each end of the body is a substantially rectangular key member 18 having reduced ends '19 proJecting longitudinally thereof and adapted to engage within the recesses 17 when the sleeves are in position to prevent any rotary movementthereof so that the same will not become displaced from within the openings 8. p

Hingedly secured to one side of the an nular flange 16 are the dust proof doors 20 which, when the sleeves are in'position, are adapted to be secured down over the outerends thereof to prevent any dust or any other foreign particles from entering the same. The rollers 7 and trunnions 9 and 10 are provided with a centrally arranged longitudinal opening 21 closed at one end and provided .at the other end with a spring held cap whereby the same may be readily filled with oil or other lubricant, said opening forming a suitable receptacle for retaining the Oil within the rollers. The tr- unuions 9 and 10 are each provided with an opening 20" adapted to communicate with the longitudinal opening 21 so as to permit a continuous flow of oil into the sleeves 13, said flow being sutficient to lubricate the bearing balls 15. Provision is made in this journal ball bearing to oil the bearings,

which will prevent rusting, but otherwise is not requisite to use oil on the balls, as it is,

an anti-friction device. Coagulation of dust or other particles in the ball pockets is enhanced by the application of oil. Therefore, it is altogether optional whether or not to use oil.

From the foregoing description taken in connection with the accompanying draw 'ings, it will be readily apparent that my improved hearing may be quickly and easily substituted for one of the 'ordinaryfljournal bearings now in use upon railway cars and the like and thatit will'preventifriction and last much longer than the ordinary journal bearings. It will be noted that in the event of the roller breaking, there will be no material damage resulting,'.hecause the shape of the recess 6 is such as to-serve as a bearing surface for the journal 01' axle.

it will be apparent that the hearing balls 15. and the sleeves 13 may be readily removed From the openings 11 and 12 for cleaningpurposes without removing the rollers 7.'

While I have shown and described the preferred form of my invention, itwill be obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying my lnventlon into practice without sacrificing any of the novel features or departing from the scope of the appended claim.

.What I claim 15:-

In a journal bearing, the combination with a body having one section formed with a recess to receive the journal and with communicating cavities open at one end, a separate section adapted to close the open ends of, said cavities, antifriction rollers arranged in said cavities and having their peripheries.

the body and disposed between said sleeves,

reduced end portions formed upon said key members and adapted to engage within said recesses to prevent the rotary movement of said sleeves. In testimony whereof I hereunto aflix my signature inthe presence of two witnesses. CHARLES DUNNING. Witnesses: V
