I '0 all whom cmwem:

Be itknown that 1, JAMES, R. Film-ems, a, citizen of the Ulilltifiil Ffaaees residing at Scranton, in the county of lfilcku. Jaime anti State of Pennsylvania, have invented certain new and useful lmprmemenis in. Axle Boxes cf which the following is a specification.

This invention relates 63o improvements in axle boxes crl le use in connection with mine cars and trucks; and more especially to lIfflQlOVB'illfiiltS shown and described. in, Letters Patent No. %89'7, iiatetl l ebruai'y 23, 1904, mid N0.' 813,962, 27, 1966; and. my object is m prcvicle a construction cf the parts of the axle be where y the bedy O1. bracket portion of em he's will be relievecl from Wear, therefore, given a longer life; anal whereby the lose motion between Wheel aiicl he); in readily taken up.

I alziain my object lav consti'ucfii ig the box in the manner illustratmi in the accompany-- ing drawings, in which,

Figure 1 presents partial view 03": a car wheelano. axle with my box applied therelo and slwwn in longitudinal section; Fig. 2, an e113; View of the be looking to the the hearing lolocli elei aticn.

Like numerals elesig'aatelilze parts in the several views.

Upon. the eiie; l the car Wheel 2, which pirei fei-alz ly is i'zc upon the axle, althou gh it may he fixed thereon, Without departing hem SQlfill? of this invention. The axle comprises a bracket member 3, which is ts securecl "co the unclersiale of the sill of a mine car, 01'.- the like, 21116. hic is proviolecl With flange 3 imi'ncm L jacenb the wheel. The low l3l16 axle box is in the form of a lTihTlfi 4; holiiiiig chamber, which is removehly mcilfiil to "a we bracket mere-- her in the f rib-eel in 1m Lefizters Patent Ho. 813,969,; '1 i'llS lubri- QETE Wheel is e aisle, is preferably ylinclrical extension a. lubricant cham- "1h ml the Wheel, as ler ent li e" *Zfiflfifil'l lcoselv inouiitecl pro decl Wifli a se 5., which a he?

- My piese i i; invention lies in the construction ancl the manner oft applying the ionsnal block 7, which is eonlainecl in the bracket member of axle box. This journal block provided a; the inward side of the axle box with a segmental or send-annular flange 8, which preferably corresponds in diameter the hub of the whee This flange is fitted into a cone spending segmental recess 9 formeo in. the bracket niemhenancl is hchl against rotary motion therein, both by the flattened top 10 of the body portion ofthe block, anal hy the lips 11, formal the cpposi ce encls the recess on the bracket member, W" i'ch engage the encls 12 of the This flange 8 preferably so mafle as be beyond the face cf the bracket, as shown, iii which case the wheel huh may be of laigei' diameter than. the flange.

This member is usually made of cast steel and the loss occurring by reason of the rliseai-fiiiig; oi a Wei-n hi'aclreh is consiclerable, to say nothing of the time wequirecl. in make the change. "E constructthe hearing: block as herein (lesciiheel, the bracket memher entirely relieved rem this Wear. Preferably I make this hearing block of cast iron, ci'i tlie same gracle as the Wheel so cat the wear will be equal between the hub and the bearing block As Wear in either hub 01' block the lost metioii may be taken up from time, to time,
