oil will run through hole I3 to said rubbing sur-~
stationary support for said shaft, and 4 is a bear

successively with the holes 9, I3 and-` I0 `in the
40_ ings 4* and 4b which ilt snugly within the sup-_,
. j port 3 and are held against rotary and. creep~
ing movements therein by a suitable locking`
member or key 5. Preferably the ends of these
half bearings meet or abut at diametrically oppo
45 site points slightly offset above and below a hori
zontal center line 5. Both half bearings 4'A and
4b are provided upon opposite sides of this cen- ~
ter line 6 with chamfered portions 1 and 5 respec
tively providing oil sumps 'I‘I and 8*.
The upper v
50 half bearing 4° has two radially extending holes
9 and I0, respectively, approximately one-six
teenth of an inch (11.1") in diameter extending
therethrough approximately eight degrees (8°)
yzabove the center line 6 in communication with
Vthe sumps 1'L and 8‘, and is` provided upon the
main bearing 4.- Foreign matter in theo'il will 40.> I,

Thus, from the foregoing it- will be -apparent
that the oil delivery from the back of the bear- ' ' _
ing 4 to the rubbing surface or contact varea I5
thereof may beeifected without breaking up the
oil fllm on saidsurface or area,Y and that the
oil supply is sufilcient to cause delivery thereof ï
