It will thus be seen that a steering column has
been provided wherein the wheel and shaft may
be expeditiously removed or replaced. To remove
the shaft 8, the arms 20 are detached from the
ears or lugs 22 thereby permitting the radial bear
ing or bushing l9 to be slipped out of the lower
the shoulder on said upper shaft section, a sleeve
secured to said housing overlying the adjacent
ends of the same and said cap member and hav
ing its upper end engaged by the outwardly ex
tending ?ange on said cap member, and means
for locking said parts in assembled relation.

The intermediate shaft section ID may then be
removed from the housing I at the upper end
thereof by screwing a suitable eye bolt into the

reversed.
It is believed that the many advantages of a
steering column constructed in accordance with
the present invention will be readily understood
and although a preferred embodiment of the de
vice as illustrated and described, it is to be un
derstood that changes in. the details of construc
tion and in the combination and arrangement
of parts may be resorted to which will fall with
in the scope of the invention as claimed.
What is claimed is:
1. A steering column of the character described
comprising a tubular housing, a removable shaft
rotatably mounted in said housing, said shaft in 40
tional shaft rotatably mounted therein, interlock
ing clutch shoulders on the adjacent ends of said
shaft sections, an annular shoulder formed on
the upper shaft section, a cap member formed
with opposed outwardly and inwardly extending
?anges seating on the upper ends of said hous
ing with the inwardly extending ?ange engag
ing the shoulder on said upper shaft section, a
sleeve secured to said housing overlying the ad
jacent ends of the same and said cap member
and having its upper end engaged by the out
wardly extending ?ange on said cap member,
said sleeve being formed with an annular groove,
?xed on the corresponding end portion of the
and oppositely disposed locking lugs on said cap
member engageable in said annular groove for
locking said parts in assembled relation.
5. A steering column of the character described

having an internal circumferential groove and
further having a longitudinal groove therein
communicating with the ?rst-named groove, a
stop projecting into the ?rst-named groove, a
cap member mounted on the shaft and engaged
with the shoulder, a lug on said cap member en

locking clutch shoulders on the adjacent ends
of said shaft sections, an annular shoulder
formed on the upper shaft section, a cap mem
engageable with the stop, and a latch on the
tion, a sleeve secured to said housing overlying
sleeve engageable with the lug for releasably se
curing the nut. against retrograde rotation in
said sleeve.
2. A steering column of the character described
