While I have described in connection with the blocks having spherical surfaces on their lowex-
resilient means as commonly used in conven
10 tional designs and provides for automatic ad
accompanying drawing, the speciilc form in
which I prefer to embody my invention, it is to
be understood that the invention is not to be lim-~

shown and described, and that, in fact, widely
30 dlil'erent means may be employed in the practice
of the broader aspects of my invention.
What I claim, therefore, and desire to secure
by Letters Patent is:
1. A’ self aligning bearing comprising a sup
porting bracket having a socket, a bearing sleeve
sides to engage said ball portion and 4beveled sur
faces on their upper side, a pin above said blocks
and supported in said side members, a pair of
wedge members mounted on said pin and engag
ing said beveled surfaces. and a spring between
said wedges to automatically urge said wedges in
opposite directions and against said blocks to hold
said blocks in locking engagement with said‘ball
portion.
