(Cl; 64-3.) 2 1 The present invention relates‘ to new and use ‘I provided therefor in said sleeve for engagement ful improvements in steering columns particularly for motor vehicles and has for its primary ob in the groove 3 at a point adjacent to but spaced from the stop 4 (see‘Figure 3). The purpose of the latch 6 will also be presently set forth. Rotatablyr mounted in the housing I is a remov ject to provide, in a manner as hereinafter set forth, a device of this character comprising a novel construction and arrangement whereby the wheel and the shaft may, when desired, be expedi tiously removed from the housing and replaced. Other objects of the invention are to provide a steering column of the aforementioned char acter which will be comparatively simple in con struction, strong, durable, compact and which able shaft which is designated generally by; ref erence character 8. The shaft 8 comprises upper, intermediate and lower sections 9, Ill-and ll, ref spectively. Mounted on the upper end. of the 10 shaft section 9 is a steering wheel I2. The-shaft sections 9 and I0 areoperatively con nected for rotation in unison by complemental clutch members is and I4 on their opposed ends. The lower end of the intermediate section [0 is All of the foregoing and still further objects and advantages of the invention will become ap 15 provided with clutch members l5 which are-en gageable with complemental clutch members l6 parent from a, study of the following speci?ca on the upper end of the section II. Thus, the tions, taken in connection with the accompany may be manufactured at low cost. ing drawings wherein like characters of reference designate corresponding parts throughout the shaft sections 9, l0 and H are connected for re tation in unison butv in a manner to permit them several views, and wherein: 20 to be. readily separated.

Figures 7 and 8 are plan views, respectively, of The section II of the shaft 8 compriseson its the opposed ends of the intermediate and lower lower end a reduction 23 terminating ina taper shaft sections. 24 for receiving a gear or knuckle. -A retaining nut 25 is threaded on the lower end‘ portion of the taper '24. The reduction 23 of the shaft sec tion H is rotatable in the member l8. This re be seen that the embodiment of the invention 40 duction 23 provides a shoulder 26 on the lower end of the shaft 8 which rests on the thrust bear-' which has been illustrated comprises a station ing it. Thus, the shaft 8v is ?rmly supported in ary tubular housing I of any suitable metal. The Figure 9 is a detail view in elevation of the shaft retaining cap member. Figure 10 is a top plan view of the housing. Referring now to the drawings in detail, it will housing I may be secured in position in the vehicle the housing I. A retaining cap member 21 is provided at the in any desired manner. Fixed on the upper end portion of the housing 45 upper end of the housing I for the shaft 8. The retaining nut 21 includes a ?at, circular top 28 ! and rising therefrom is a sleeve 2. having a circular, central opening 29 therein The sleeve is provided with an internal cir which accommodates the shaft section 9. The cumferential groove or channel 3. A stop 4 is pro retaining nut 2‘! further includes lugs 30 which vided in the groove 3, the purpose of which will be presently set forth. The sleeve 2 is further 50 are insertable in the groove 3 through the grooves 5 for anchoring said nut in the sleeve 2. The provided with vertical grooves 5 which extend from the upper end of said sleeve to the circum upper shaft section 9 is formed to provide a ferential groove 3. Pivotally mounted on the shoulder 3| with which the top 28 of the cap sleeve 2 is a spring pressed thumb or ?nger re member 21 is engageable for anchoring said sec tracted latch 6 which is operable in an opening 55 tion 9 in the housing l. ~ 2,409,062 3 4 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. 3. A steering column of the character described end portion of the housing I'. In this manner the shaft section Il may be readily withdrawn from the lower end of the housing I. , The inter including a tubular housing, a removable sec tional shaft rotatably mounted therein, inter mediate section I0 may also be removed in this manner, if desired. As illustrated to advantage locking clutch shoulders on the adjacent ends of said shaft sections, an annular shoulder in Figure 3 of the drawings, the latch 6 is en gageable behind the lug 30 which is engaged with the stop 4 for preventing retrograde rotation of ber formed with opposed outwardly and inwardly formed on the upper shaft section, a cap mem extending ?anges seating on the upper ends of the retaining cap member 21. To remove the wheel l2 and the shaft section 9, the latch 5 is said housing with the inwardly extending ?ange disengaged or withdrawn from the groove 3 for ‘ tion, a sleeve secured to said housing overlying engaging the shoulder on said upper shaft sec the adjacent ends of the same and said cap mem ber and having its upper end engaged by the lug 30 thereon with the grooves 5. The cap mem ber 21 may then be lifted out of the sleeve 2 for 20 outwardly extending ?ange on said cap member, permitting the nut 21 to be turned to align the permitting disconnection of the shaft section 9. 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 socket l1. Of course, to reassemble the steering and oppositely disposed locking lugs on said cap member for locking said parts in assembled rela tion. 4. A steering column of the character described " including a tubular housing, a removable sec column the foregoing operation is substantially 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.
