LOCOMOTIVE DRIVING BOX Filed Aug. 12, 1927 2 Sheets-Sheet 2 2 2 22 i7 lNVENTOR 2 6 ATTORNEYS Patented Aug. 1,1933 7 This invention relates to locomotive driving boxes particularly to bearing 111831181011 such boxes below the center of the journal.
. At times certain driving strains in alocom otive have a tendency to move the box upwardly with relation to the journal. Such movements result in abnormal strains on certain parts of thebox, particularly the main bearing when it reseats itself en the journal, and sometimes such movements cause breakage of lubricator and other parts below thejournal.
' Iaimto overcome'such diffi culties by the use of 'bear'infgs carried by the box structure below the center of the journal, l5
in'gs under the main bearing.
How the foregoing objects "and advantages, together with others which will occur tolthose skilled in the art, are obtained will be clear from the description considered in connection with the accompanying drawings which illus tratea preferred embodiment of the invention, and in which. 7

the bearing side of the journal'5 from the bottom 6. A bear- ,ing backing member '7 is provided above the journal and this member and the legs 4: are provided with shoulders. 8 and 9, respectively, which 00- bottom and having upwardly extending legs, a
operate tosupport thebox on the journal. A crown bearingll) is interposed'betweenthe back mg member 8 and the journal. The wedges 11 are adapted to retain the legs of the bearing 10 against the shoulders 12 formed on the dovetail shaped spacing lugs 13 extending inwardly from each leg 4. I
A morespeciiicobjectis the provision of sim pleand effective means for adjustingsuch bear journal 'as 'wear occursin' the tion to this particular type of box as it may be the bottom is provide a lubricator pocket theretree-t; STA PAT T OFFICE between and a bearing pocket on each side of the box between the legs 4.
The lubricator may be er any suitable type. That shown includes a spring 15, a follower plate 16, a grease cake 17 and a perforated plate 18. t A bearing 19 isprovided in'each pocket at the sides of the box and is supported therein by the,
wedge 20 having a tongue and groove engage- .gt ment 2 1 with the bottom 6. The wedge also has a tongue and groove "engagement 22 with the bearing 19. The upper face of the wedge. 20 and the lower'face of the bearing 19 are oppositely inclined and cooperate to s upportthe bearingand retain it adjacent the shoulder 23 formed on the. lug 13. j 'A depending apertured lug2 l is provided at the outer end of the wedge 20 anda bolt 25 secured in the bottom 6 extends outwardly through the aperture in the lug 24. Adjusting and lock nuts 26 and 2'7, respectively, are provided on the bolt 25'. g
When wear occurs in the crown bearing 10 the bearings 19 are advanced by machining off the top' shoulders 28'and advancing the wedge. The adjustment of the bearings should be close enough to almost immediately arrest any up- Ward movement of the box relative tothe jour nal, but these hearings should be far enough away from the journal to allow-a film of lubricant to pass around to the crown bearing.
In the modification of Fig.3 I have provided a recess 29 in which shims 30 are provided. This arrangement may be adjusted by removing one or more shims and advancing the wedge a corresponding distance.
According to the foregoing I have provided bearing means below the center of the journal which are simple and rugged in construction *and which will effectively prevent abnormal movements of the box upwardly withrelation so i to the journal. Furthermore, I have provided 7 simple and effective means forjadjusting such bearings. r
